Description
FIELD OF THE INVENTION
[0001] Embodiments of the invention relate to a liquid crystal
display (LCD) and a LCD panel.
BACKGROUND
[0002] A configuration of conventional LCDs generally comprises a
display panel having a sub-pixel array disposed thereon, a source
driver for driving source electrodes of the sub-pixels and having
data lines, a gate driver for driving gate electrodes of the
sub-pixels and having scan lines, a timing controller and a
backlight unit.
[0003] In conventional technologies, a Dual-Gate technology and a
Triple-Gate technology respectively increase the data lines by more
than one or two times. Though both technologies may reduce the
cost, the charge time of the pixels is decreased as well, making it
difficult to meet the requirement on charge time for
high-resolution and stereoscopic displays.
[0004] For the purpose of meeting the requirement on charge time
for high-resolution stereoscopic (3D) displays, the Chinese patent
publication CN 101494020 titled "A Display Device" discloses a
solution of halving the scan lines in the gate driver while
doubling the data lines in the source driver, which may double the
charge time of the pixels. However, with the development of 3D
displays having a refresh rate of 240 Hz and higher resolutions, it
requires an ever shorter time for charging hold capacitors when
writing pixels. Therefore, it still can not meet the high quality
requirement of 3D high resolution display with 240 Hz refresh rate
by halving the charge time.
[0005] Moreover, in terms of inversion manners, dot inversion may
provides the best picture quality with the least flicker. However,
for a configuration using the dot inversion as illustrated in FIGS.
2 and 3, with each frame, a polarity of a drive signal on each data
line has to be inverted once after the scan time of each scan line,
thereby consuming much power and easily increasing the temperature
of the source driver on the LCD panel.

and (Ni+N)th rows are all connected to the (i+1)th scan line
G(i+1), i is a non-negative integer less than or equal to (n/N)-1,

blue sub-pixel at the third row and mth column is output at
S(9m);
[0049] . . . .
[0050] when G2 is turned on, data on the 4th, 5th, 6th rows is
written to corresponding pixels via the corresponding data lines.
For example, data R.sub.4,1 corresponding to the red sub-pixel in
the fourth row and first column is output at S1, data R.sub.5,1
corresponding to the red sub-pixel in the fifth row and first
column is output at S2, data R.sub.6,1 corresponding to the red

corresponding to the blue sub-pixel at the fifth row and mth column
is output at S(9m-1), data B.sub.6,m corresponding to the blue
sub-pixel at the sixth row and mth column is output at S(9m);
[0051] when G(n/3-1) is turned on, data on the (n-5)th, (n-4)th,
(n-3)th rows is written to corresponding pixels via the
corresponding data lines. For example, data R.sub.n-5,1
corresponding to the red sub-pixel in the (n-5)th row and first
column is output at S1, data R.sub.n-4,1 corresponding to the red
sub-pixel in the (n-4)th row and first column is output at S2, data
R.sub.n-3,1 corresponding to the red sub-pixel at the (n-3)th row
and first column is output at S3, . . . , data B.sub.n-5,m
corresponding to the blue sub-pixel at the (n-5)th row and mth

the (n-3)th row and mth column is output at S(9m);
[0052] when G(n/3) is turned on, data on the (n-2)th, (n-1)th, nth
rows is written to corresponding pixels via the corresponding data
lines. For example, data corresponding to the red sub-pixel in the
(n-2)th row and first column is output at S1, data R.sub.n-2,1
corresponding to the red sub-pixel in the (n-1)th row and first
column is output at S2, data R.sub.n,1 corresponding to the red
sub-pixel at the nth row and first column is output at S3, . . . ,
data B.sub.n-2,m corresponding to the blue sub-pixel at the (n-2)th

blue sub-pixel at the (n-1)th row and mth column is output at
S(9m-1), data B.sub.n,m corresponding to the blue sub-pixel at the
nth row and mth column is output at S(9m).
[0053] In the embodiment, FIGS. 5 and 6 are diagrams schematically
illustrating polarity inversion between two adjacent frames in
accordance with the embodiment of the invention. As illustrated in
FIG. 5 (the Yth frame) and FIG. 6 (the (Y+1)th frame), when seen
from the side of the display panel, the inversion manner for the
pixels is 1+2 dot inversion, that is, K rows of pixels are 2 dot
inverted, and the pixels in the remaining rows are dot inverted,
where K is an integer grater than 1 and less than n, and the
remainder of (K-1)/3 is 2 or 0. In terms of the whole picture, of
each row other than the first and the nth row and starting from the
second row, one row is dot inverted, the following two adjacent
rows are two dot inverted, and so on. When seen from the source
driver side, for the Yth frame, drive signals on the same data line
have the same polarity; for the next frame the (Y+1)th frame, drive
signals on that data line have a polarity opposite to that of the
driver signals for the previous frame the Yth frame, and drive
signals on two adjacent data lines are of opposite polarities when
displaying the Yth frame. For example, the first and fourth drive
signals on the first data line S1 of FIG. 5 are both positive. In
the next frame, the first and fourth drive signals on the first
data line S1 of FIG. 6 are both negative. The first data line S1
and the second data line S2 in both FIG. 5 and FIG. 6 are always of
opposite polarities. Therefore, in comparison with the conventional
art in which the polarity of the drive signals on each data line
has to be inverted once after the scan time of each scan line
within one frame, the above technical solution may guarantee the
picture quality while reducing the power consumption and the system
temperature.
[0054] In the embodiment, FIG. 7 is a diagram schematically
illustrating polarity inversion on source lines S(6j+1), S(6j+2),
S(6j+3), S(6j+4), S(6j+5), S(6j+6), S(6j+7) (here j is an integer
larger than or equal to 0) of the source driver between different
frames, where the high/low level indicates the polarities output on
the data lines instead of the specific data output on the data
lines.
Embodiment 2
[0055] As illustrated in FIG. 8, in the embodiment, N is equal to 3
and M is also 3, RGB sub-pixels of the same pixel are disposed
horizontally. There are n/3 scan lines and 9m+1 data lines, that
is, the scan lines for pixels in the (3i+1)th, (3i+2)th, (3i+3)th
row are connected together and then connected to the (i+1)th line
G(i+1) of the gate driver, where i is a non-negative integer less
than or equal to (n/3)-1; sub-pixels in the jth column are
respectively connected to the (3j-2)th, (3j-1)th, (3j)th, (3j-1)th,
(3j)th, (3j+1)th data lines S(3j-2), S(3j-1), S(3j), S(3j-1),
S(3j), S(3j-1), S(3j+1), according to the different (6i+1)th,
(6i+2)th, (6i+3)th, (6i+4)th, (6i+5)th, (6i+6)th rows of the
sub-pixel matrix where the sub-pixels are located; where j is an
integer greater than or equal to 1 and less than or equal to
3m.
[0056] A frame is realized in the following way:
[0057] when G1 is turned on, data on the 1st, 2ed, 3rd rows is
written to corresponding pixels via the corresponding data lines.
For example, data R.sub.1,1 corresponding to the red sub-pixel in
the first row and first column is output at S1, data R.sub.2,1
corresponding to the red sub-pixel in the second row and first
column is output at S2, data R.sub.3,1 corresponding to the red
sub-pixel at the third row and first column is output at S3, . . .
, data B.sub.1,m corresponding to the blue sub-pixel at the first
row and mth column is output at S(9m-2), data B.sub.2,m
corresponding to the blue sub-pixel at the second row and mth
column is output at S(9m-1), data B.sub.3,m corresponding to the
blue sub-pixel at the third row and mth column is output at
S(9m);
[0058] when G2 is turned on, data on the 4th, 5th, 6th rows is
written to corresponding pixels via the corresponding data lines.
For example, data R.sub.4,1 corresponding to the red sub-pixel in
the fourth row and first column is output at S2, data R.sub.5,1
corresponding to the red sub-pixel in the fifth row and first
column is output at S3, data R.sub.6,1 corresponding to the red
sub-pixel at the sixth row and first column is output at S4, . . .
, data B.sub.4,m corresponding to the blue sub-pixel at the fourth
row and mth column is output at S(9m-1), data B.sub.5,m
corresponding to the blue sub-pixel at the fifth row and mth column
is output at S(9m), data B.sub.6,m corresponding to the blue
sub-pixel at the sixth row and mth column is output at S(9m+1);
[0059] . . . .
[0060] when G(n/3-1) is turned on, data on the (n-5)th, (n-4)th,
(n-3)th rows is written to corresponding pixels via the
corresponding data lines. For example, data R.sub.n-5,1
corresponding to the red sub-pixel in the (n-5)th row and first
column is output at S1, data R.sub.n-4,1 corresponding to the red
sub-pixel in the (n-4)th row and first column is output at S2, data
R.sub.n-3,1 corresponding to the red sub-pixel at the (n-3)th row
and first column is output at S3, . . . , data B.sub.n-5,m
corresponding to the blue sub-pixel at the (n-5)th row and mth
column is output at S(9m-2), data B.sub.n-4,m corresponding to the
blue sub-pixel at the (n-4)th row and mth column is output at
S(9m-1), data B.sub.n-3,m corresponding to the blue sub-pixel at
the (n-3)th row and mth column is output at S(9m);
[0061] when G(n/3) is turned on, data on the (n-2)th, (n-1)th, nth
rows is written to corresponding pixels via the corresponding data
lines. For example, data R.sub.n-2,1 corresponding to the red
sub-pixel in the (n-2)th row and first column is output at S2, data
R.sub.n-1,1 corresponding to the red sub-pixel in the (n-1)th row
and first column is output at S3, data R.sub.n,1 corresponding to
the red sub-pixel at the nth row and first column is output at S4,
. . . , data B.sub.n-2,m corresponding to the blue sub-pixel at the
(n-2)th row and mth column is output at S(9m-1), data B.sub.n-1,m
corresponding to the blue sub-pixel at the (n-1)th row and mth
column is output at S(9m), data B.sub.n,m corresponding to the blue
sub-pixel at the nth row and mth column is output at S(9m+1).
[0062] In the embodiment, as illustrated in the Yth frame and the
(Y+1)th frame (FIG. 9), when seen from the side of the display
panel, the inversion manner for the pixels is dot inversion. When
seen from the gate driver side, for the Yth frame, drive signals on
the same data line have the same polarity; for the next frame the
(Y+1)th frame, drive signals on that data line have a polarity
opposite to that of the driver signals for the previous frame the
Yth frame, and drive signals on two adjacent data lines are of
opposite polarities when displaying the Yth frame. For example, the
first and seventh drive signals (the seventh not shown in the
figure) on the first data line S1 of FIG. 8 are both positive. In
the next frame, the first and seventh drive signals (the seventh
not shown in the figure) on the first data line S1 of FIG. 9 are
both negative. The first data line S1 and the second data line S2
in both FIG. 8 and FIG. 9 are always of opposite polarities.
Therefore, in comparison with the conventional art in which the
polarity of the drive signals on each data line has to be inverted
once after the scan time of each scan line within one frame, the
above technical solution may guarantee the picture quality while
reducing the power consumption and the system temperature.
[0063] FIG. 7 is a diagram schematically illustrating polarity
inversion on data lines S(6j+1), S(6j+2), S(6j+3), S(6j+4),
S(6j+5), S(6j+6), S(6j+7) (here j is an integer larger than or
equal to 0) of the source driver between different frames, where
the high/low level indicates the polarities output on the data
lines instead of the specific data output on the data lines.
Embodiment 3
[0064] As illustrated in FIG. 10, in the embodiment, N is equal to
3 and M is equal to 4, RGBY sub-pixels of the same pixel are
disposed horizontally. There are n/3 scan lines and 12m data lines,
that is, the scan lines for pixels in the (3i+1)th, (3i+2)th,
(3i+3)th row are connected together and then connected to the
(i+1)th line G(i+1) of the gate driver, where i is a non-negative
integer less than or equal to (n/3)-1; sub-pixels in the jth column
are respectively connected to the (3j-2)th, (3j-1)th, (3j)th data
lines S(3j-3), S(3j-1), S(3j), according to the different (3i+1)th,
(3i+2)th, (3i+3)th rows of the sub-pixel matrix where the
sub-pixels are located; where j is an integer greater than or equal
to 1 and less than or equal to 4m.
[0065] A frame is realized in the following way:
[0066] when G1 is turned on, data on the 1st, 2ed, 3rd rows is
written to corresponding pixels via the corresponding data lines.
For example, data R.sub.1,1 corresponding to the red sub-pixel in
the first row and first column is output at S1, data R.sub.2,1
corresponding to the red sub-pixel in the second row and first
column is output at S2, data R.sub.3,1 corresponding to the red
sub-pixel at the third row and first column is output at S3, . . .
, data Y.sub.1,m corresponding to the yellow sub-pixel at the first
row and mth column is output at S(12m-2), data Y.sub.2,m
corresponding to the yellow sub-pixel at the second row and mth
column is output at S(12m-1), data corresponding to the yellow
sub-pixel at the third row and mth column is output at S(12m);
[0067] when G2 is turned on, data on the 4th, 5th, 6th rows is
written to corresponding pixels via the corresponding data lines.
For example, data R.sub.4,1 corresponding to the red sub-pixel in
the fourth row and first column is output at S1, data R.sub.5,1
corresponding to the red sub-pixel in the fifth row and first
column is output at S2, data R.sub.6,1 corresponding to the red
sub-pixel at the sixth row and first column is output at S3, . . .
, data Y.sub.4,m corresponding to the yellow sub-pixel at the
fourth row and mth column is output at S(12m-2), data Y.sub.5,m
corresponding to the yellow sub-pixel at the fifth row and mth
column is output at S(12m-1), data Y.sub.6,m corresponding to the
yellow sub-pixel at the sixth row and mth column is output at
S(12m);
[0068] . . . . .
[0069] when G(n/3-1) is turned on, data on the (n-5)th, (n-4)th,
(n-3)th rows is written to corresponding pixels via the
corresponding data lines. For example, data R.sub.n-5,1
corresponding to the red sub-pixel in the (n-5)th row and first
column is output at S1, data R.sub.n-4,1 corresponding to the red
sub-pixel in the (n-4)th row and first column is output at S2, data
R.sub.n-3,1 corresponding to the red sub-pixel at the (n-3)th row
and first column is output at S3, . . . , data Y.sub.n-5,m
corresponding to the yellow sub-pixel at the (n-5)th row and mth
column is output at S(12m-2), data Y.sub.n-4,m corresponding to the
yellow sub-pixel at the (n-4)th row and mth column is output at
S(12m-1), data Y.sub.n-3,m corresponding to the yellow sub-pixel at
the (n-3)th row and mth column is output at S(12m);
[0070] when G(n/3) is turned on, data on the (n-2)th, (n-1)th, nth
rows is written to corresponding pixels via the corresponding data
lines. For example, data R.sub.n-2,1 corresponding to the red
sub-pixel in the (n-2)th row and first column is output at S1, data
R.sub.n-1,1 corresponding to the red sub-pixel in the (n-1)th row
and first column is output at S2, data R.sub.n,1 corresponding to
the red sub-pixel at the nth row and first column is output at S3,
. . . , data Y.sub.n-2,m corresponding to the yellow sub-pixel at
the (n-2)th row and mth column is output at S(12m-2), data

row and mth column is output at S(12m-1), data Y.sub.n,m
corresponding to the yellow sub-pixel at the nth row and mth column
is output at S(12m).
[0071] In the embodiment, as illustrated in the Yth frame (FIG. 10)
and the (Y+1)th frame (FIG. 11), when seen from the side of the
display panel, the inversion manner for the pixels is 1+2 dot
inversion, that is, K rows of pixels are 2 dot inverted, and the
pixels in the remaining rows are dot inverted, where K is an
integer grater than 1 and less than n, and the remainder of (K-1)/3
is 2 or 0. In terms of the whole picture, of each row other than
the first and the nth row and starting from the second row, one row
is dot inverted, the following two adjacent rows are two dot
inverted, and so on. When seen from the gate driver side, for the
Yth frame, drive signals on the same data line have the same
polarity; for the next frame the (Y+1)th frame, drive signals on
that data line have a polarity opposite to that of the driver
signals for the previous frame the Yth frame, and drive signals on
two adjacent data lines are of opposite polarities when displaying
the Yth frame. For example, the first and seventh drive signals
(the seventh not shown in the figure) on the first data line S1 of
FIG. 10 are both positive. In the next frame, the first and seventh
drive signals (the seventh not shown in the figure) on the first
data line S1 of FIG. 11 are both negative. The first data line S1
and the second data line S2 in both FIG. 10 and FIG. 11 are always
of opposite polarities. Therefore, in comparison with the
conventional art in which the polarity of the drive signals on each
data line has to be inverted once after the scan time of each scan
line within one frame, the above technical solution may guarantee
the picture quality while reducing the power consumption and the
system temperature.
[0072] In the embodiment, FIG. 7 is a diagram schematically

S(6j+3), S(6j+4), S(6j+5), S(6j+6), S(6j+7) of the source driver
between different frames, where the high/low level indicates the
polarities output on the data lines instead of the specific data
output on the data lines.

3 and M is equal to 4, RGBY sub-pixels of the same pixel are
disposed horizontally. There are n/3 scan lines and 12m+1 data
lines, that is, the scan lines for pixels in the (3i+1)th,
(3i+2)th, (3i+3)th row are connected together and then connected to
the (i+1)th line G(i+1) of the gate driver, where i is a
non-negative integer less than or equal to (n/3)-1; sub-pixels in
the jth column are respectively connected to the (3j-2)th,
(3j-1)th, (3j)th, (3j-1)th, (3j)th, (3j+1)th data lines S(3j-2),
S(3j-1), S(3j), S(3j-1), S(3j), S(3j-1), S(3j+1), according to the
different (6i+1)th, (6i+2)th, (6i+3)th, (6i+4)th, (6i+5)th,
(6i+6)th rows of the sub-pixel matrix where the sub-pixels are
located; where j is an integer greater than or equal to 1 and less
than or equal to 4m.
[0074] A frame is realized in the following way:
[0075] when G1 is turned on, data on the 1st, 2ed, 3rd rows is
written to corresponding pixels via the corresponding data lines.
For example, data R.sub.1,1 corresponding to the red sub-pixel in

For example, data R.sub.4,1 corresponding to the red sub-pixel in
the fourth row and first column is output at S2, data R.sub.5,1
corresponding to the red sub-pixel in the fifth row and first
column is output at S3, data R.sub.6,1 corresponding to the red
sub-pixel at the sixth row and first column is output at S4, . . .
, data Y.sub.4,m corresponding to the yellow sub-pixel at the

corresponding to the yellow sub-pixel at the fifth row and mth
column is output at S(12m), data Y.sub.6,m corresponding to the
yellow sub-pixel at the sixth row and mth column is output at
S(12m+1);
[0077] . . . .
[0078] when G(n/3-1) is turned on, data on the (n-5)th, (n-4)th,
(n-3)th rows is written to corresponding pixels via the
corresponding data lines. For example, data R.sub.n-5,1
corresponding to the red sub-pixel in the (n-5)th row and first
column is output at S1, data R.sub.n-4,1 corresponding to the red
sub-pixel in the (n-4)th row and first column is output at S2, data

S(12m-1), data Y.sub.n-3,m corresponding to the yellow sub-pixel at
the (n-3)th row and mth column is output at S(12m);
[0079] when G(n/3) is turned on, data on the (n-2)th, (n-1)th, nth
rows is written to corresponding pixels via the corresponding data
lines. For example, data R.sub.n-2,1 corresponding to the red
sub-pixel in the (n-2)th row and first column is output at S2, data

[0080] In the embodiment, as illustrated in the Yth frame (FIG. 12)
and the (Y+1)th frame (FIG. 13), when seen from the side of the
display panel, the inversion manner for the pixels is dot
inversion. When seen from the gate driver side, for the Yth frame,
drive signals on the same data line have the same polarity; for the
next frame the (Y+1)th frame, drive signals on that data line have
a polarity opposite to that of the driver signals for the previous
frame the Yth frame, and drive signals on two adjacent data lines
are of opposite polarities when displaying the Yth frame. For
example, the first and seventh drive signals (the seventh not shown
in the figure) on the first data line S1 of FIG. 12 are both
positive. In the next frame, the first and seventh drive signals
(the seventh not shown in the figure) on the first data line S1 of
FIG. 13 are both negative. The first data line S1 and the second
data line S2 in both FIG. 12 and FIG. 13 are always of opposite
polarities. Therefore, in comparison with the conventional art in
which the polarity of the drive signals on each data line has to be
inverted once after the scan time of each scan line within one
frame, the above technical solution may guarantee the picture
quality while reducing the power consumption and the system
temperature.

equal to 0) of the source driver between different frames, where
the high/low level indicates the polarities output on the data

[0083] A frame is realized in the following way:
[0084] when G1 is turned on, data on the 1st, 2ed, 3rd rows is
written to corresponding pixels via the corresponding data lines.
For example, data R.sub.1,1 corresponding to the red sub-pixel in

row and mth column is output at S(15m-2), data W.sub.5,m
corresponding to the white sub-pixel at the fifth row and mth
column is output at S(15m-1), data W.sub.6,m corresponding to the
white sub-pixel at the sixth row and mth column is output at
S(15m);
[0086] . . . .
[0087] when G(n/3-1) is turned on, data on the (n-5)th, (n-4)th,
(n-3)th rows is written to corresponding pixels via the
corresponding data lines. For example, data R.sub.n-5,1
corresponding to the red sub-pixel in the (n-5)th row and first
column is output at S1, data R.sub.n-4,1 corresponding to the red
sub-pixel in the (n-4)th row and first column is output at S2, data
R.sub.n-3,1 corresponding to the red sub-pixel at the (n-3)th row
and first column is output at S3, . . . , data W.sub.n-5,m
corresponding to the white sub-pixel at the (n-5)th row and mth
column is output at S(15m-2), data W.sub.n-4,m corresponding to the
white sub-pixel at the (n-4)th row and mth column is output at
S(15m-1), data W.sub.n-3,m corresponding to the white sub-pixel at
the (n-3)th row and mth column is output at S(15m);
[0088] when G(n/3) is turned on, data on the (n-2)th, (n-1)th, nth
rows is written to corresponding pixels via the corresponding data
lines. For example, data R.sub.n-2,1 corresponding to the red
sub-pixel in the (n-2)th row and first column is output at S1, data
R.sub.n-1,1 corresponding to the red sub-pixel in the (n-1)th row
and first column is output at S2, data R.sub.n,1 corresponding to
the red sub-pixel at the nth row and first column is output at S3,
. . . , data W.sub.n-2,m corresponding to the white sub-pixel at
the (n-2)th row and mth column is output at S(15m-2), data
W.sub.n-1,m corresponding to the white sub-pixel at the (n-1)th row
and mth column is output at S(15m-1), data W.sub.n,m corresponding
to the white sub-pixel at the nth row and mth column is output at
S(15m).
[0089] In the embodiment, as illustrated in the Yth frame (FIG. 14)
and the (Y+1)th frame (FIG. 15), when seen from the side of the
display panel, the inversion manner for the pixels is 1+2 dot
inversion, that is, K rows of pixels are 2 dot inverted, and the
pixels in the remaining rows are dot inverted, where K is an
integer grater than 1 and less than n, and the remainder of (K-1)/3
is 2 or 0. In terms of the whole picture, of each row other than
the first and the nth row and starting from the second row, one row
is dot inverted, the following two adjacent rows are two dot
inverted, and so on. When seen from the gate driver side, for the
Yth frame, drive signals on the same data line have the same
polarity; for the next frame the (Y+1)th frame, drive signals on
that data line have a polarity opposite to that of the driver
signals for the previous frame the Yth frame, and drive signals on
two adjacent data lines are of opposite polarities when displaying
the Yth frame. For example, the first and seventh drive signals
(the seventh not shown in the figure) on the first data line S1 of
FIG. 14 are both positive. In the next frame, the first and seventh
drive signals (the seventh not shown in the figure) on the first
data line S1 of FIG. 15 are both negative. The first data line S1
and the second data line S2 in both FIG. 14 and FIG. 15 are always
of opposite polarities. Therefore, in comparison with the
conventional art in which the polarity of the drive signals on each
data line has to be inverted once after the scan time of each scan
line within one frame, the above technical solution may guarantee
the picture quality while reducing the power consumption and the
system temperature.
[0090] In the embodiment, FIG. 7 is a diagram schematically
illustrating polarity inversion on source lines S(6j+1), S(6j+2),
S(6j+3), S(6j+4), S(6j+5), S(6j+6), S(6j+7) of the source driver
between different frames, where the high/low level indicates the
polarities output on the data lines instead of the specific data
output on the data lines.
Embodiment 6
[0091] As illustrated in FIG. 16, in the embodiment, N is equal to
3 and M is equal to 5, RGBYW sub-pixels of the same pixel are
disposed horizontally. There are n/3 scan lines and 15m+1 data
lines, that is, the scan lines for pixels in the (3i+1)th,
(3i+2)th, (3i+3)th row are connected together and then connected to
the (i+1)th line G(i+1) of the gate driver, where i is a
non-negative integer less than or equal to (n/3)-1; sub-pixels in
the jth column are respectively connected to the (3j-2)th,
(3j-1)th, (3j)th, (3j-1)th, (3j)th, (3j+1)th data lines S(3j-2),
S(3j-1), S(3j), S(3j-1), S(3j), S(3j-1), S(3j+1), according to the
different (6i+1)th, (6i+2)th, (6i+3)th, (6i+4)th, (6i+5)th,
(6i+6)th rows of the sub-pixel matrix where the sub-pixels are
located; where j is an integer greater than or equal to 1 and less
than or equal to 5m.
[0092] A frame is realized in the following way:
[0093] when G1 is turned on, data on the 1st, 2ed, 3rd rows is
written to corresponding pixels via the corresponding data lines.
For example, data R.sub.1,1 corresponding to the red sub-pixel in
the first row and first column is output at S1, data R.sub.2,1
corresponding to the red sub-pixel in the second row and first
column is output at S2, data R.sub.3,1 corresponding to the red
sub-pixel at the third row and first column is output at S3, . . .
, data W.sub.1,m corresponding to the white sub-pixel at the first
row and mth column is output at S(15m-2), data W.sub.2,m
corresponding to the white sub-pixel at the second row and mth
column is output at S(15m-1), data W.sub.3,m corresponding to the
white sub-pixel at the third row and mth column is output at
S(15m);
[0094] when G2 is turned on, data on the 4th, 5th, 6th rows is
written to corresponding pixels via the corresponding data lines.
For example, data R.sub.4,1 corresponding to the red sub-pixel in
the fourth row and first column is output at S2, data R.sub.5,1
corresponding to the red sub-pixel in the fifth row and first
column is output at S3, data R.sub.6,1 corresponding to the red
sub-pixel at the sixth row and first column is output at S4, . . .
, data W.sub.4,m corresponding to the white sub-pixel at the fourth
row and mth column is output at S(15m-1), data W.sub.5,m
corresponding to the white sub-pixel at the fifth row and mth
column is output at S(15m), data W.sub.6,m corresponding to the
white sub-pixel at the sixth row and mth column is output at
S(15m+1);
[0095] . . . .
[0096] when G(n/3-1) is turned on, data on the (n-5)th, (n-4)th,
(n-3)th rows is written to corresponding pixels via the
corresponding data lines. For example, data R.sub.n-5,1
corresponding to the red sub-pixel in the (n-5)th row and first
column is output at S1, data R.sub.n-4,1 corresponding to the red
sub-pixel in the (n-4)th row and first column is output at S2, data
R.sub.n-3,1 corresponding to the red sub-pixel at the (n-3)th row
and first column is output at S3, . . . , data W.sub.n-5,m
corresponding to the white sub-pixel at the (n-5)th row and mth
column is output at S(15m-2), data W.sub.n-4,m corresponding to the
blue sub-pixel at the (n-4)th row and mth column is output at
S(15m-1), data W.sub.n-3,m corresponding to the blue sub-pixel at
the (n-3)th row and mth column is output at S(15m);
[0097] when G(n/3) is turned on, data on the (n-2)th, (n-1)th, nth
rows is written to corresponding pixels via the corresponding data
lines. For example, data R.sub.n-2,1 corresponding to the red
sub-pixel in the (n-2)th row and first column is output at S2, data
R.sub.n-1,1 corresponding to the red sub-pixel in the (n-1)th row
and first column is output at S3, data R.sub.n,1 corresponding to
the red sub-pixel at the nth row and first column is output at S4,
. . . , data W.sub.n-2,m corresponding to the white sub-pixel at
the (n-2)th row and mth column is output at S(15m-1), data
W.sub.n-1,m corresponding to the white sub-pixel at the (n-1)th row
and mth column is output at S(15m), data W.sub.n,m corresponding to
the blue sub-pixel at the nth row and mth column is output at
S(15m+1).
[0098] In the embodiment, as illustrated in the Yth frame (FIG. 16)
and the (Y+1)th frame (FIG. 17), when seen from the side of the
display panel, the inversion manner for the pixels is dot
inversion. When seen from the gate driver side, for the Yth frame,
drive signals on the same data line have the same polarity; for the
next frame the (Y+1)th frame, drive signals on that data line have
a polarity opposite to that of the driver signals for the previous
frame the Yth frame, and drive signals on two adjacent data lines
are of opposite polarities when displaying the Yth frame. For
example, the first and seventh drive signals (the seventh not shown
in the figure) on the first data line S1 of FIG. 16 are both
positive. In the next frame, the first and seventh drive signals
(the seventh not shown in the figure) on the first data line S1 of
FIG. 17 are both negative. The first data line S1 and the second
data line S2 in both FIG. 16 and FIG. 17 are always of opposite
polarities. Therefore, in comparison with the conventional art in
which the polarity of the drive signals on each data line has to be
inverted once after the scan time of each scan line within one
frame, the above technical solution may guarantee the picture
quality while reducing the power consumption and the system
temperature.
[0099] FIG. 7 is a diagram schematically illustrating polarity
inversion on data lines S(6j+1), S(6j+2), S(6j+3), S(6j+4),
S(6j+5), S(6j+6), S(6j+7) (here j is an integer larger than or
equal to 0) of the source driver between different frames, where
the high/low level indicates the polarities output on the data
lines instead of the specific data output on the data lines.
[0100] What are described above is related to the illustrative
embodiments of the disclosure only and not limitative to the scope
of the disclosure. As N increases, the number of needed scan lines
of the gate driver is 1/N, the charge time for each pixel is N
times the original charge time, while the needed data lines is
multiplied by N. The choosing of N may be determined in
consideration of various factors such as cost, process, and revenue
and so on. For example, N may also be an odd number such as 5 and
7. Moreover, N may be selected as multiple values for the same
display device, according to the value of n, such as, n=8, a
combination of N1-3 and N2=5. The above description is only
directed to the preferable case of N=3, and n being an integer
multiple of N. however, the invention is not limited to the case of
N=3 and n being an integer multiple of N.
[0101] What are described above is related to the illustrative
embodiments of the disclosure only and not (imitative to the scope
of the disclosure; the scopes of the disclosure are defined by the
