Application Serial Number 98107430, filed Mar. 6, 2009, which is
herein incorporated by reference.

[0003] The present invention relates to a displaying apparatus.
More particularly, the present invention relates to a 2D/3D image
displaying apparatus.
[0004] 2. Description of Related Art
[0005] For a conventional display for displaying three-dimensional
(3D) images, it usually produces binocular disparity by temporally
or spatially multiplexing left and right views. However, temporally
multiplexing views easily causes images to flicker, and spatially
multiplexing views easily causes resolution of images to
deteriorate.
[0006] On the other hand, for a conventional display for displaying
two-dimensional (2D) images, in order to solve problems about
viewing angles, a liquid crystal display with multi-domain vertical
alignment (MVA) technique is developed. In the MVA liquid crystal
display, a liquid crystal area is divided into multiple areas so
that liquid crystal molecules incline to multiple directions to
increase viewing angles of the liquid crystal display. Moreover, in
order to further solve problems about color wash-out in the MVA
liquid crystal display, prior arts also provide several
solutions.
[0007] However, for the present art, the liquid crystal displays
are mostly provided for processing only 3D or 2D images so as to
solve respective problems. Thus, it is necessary to provide a
displaying apparatus capable of selectively displaying 2D or 3D
images and solving the foregoing problems of displaying 2D and 3D
images in the meantime.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] In the following detailed description, the embodiments of
the present invention have been shown and described. As will be
realized, the invention is capable of modification in various
respects, all without departing from the invention. Accordingly,
the drawings and description are to be regarded as illustrative in
nature, and not restrictive.
[0021] FIG. 1 illustrates a two-dimensional/three-dimensional
(2D/3D) image displaying apparatus according to an embodiment of
the present invention. The 2D/3D image displaying apparatus 100
includes a plurality of data lines (e.g. D1, D2, . . . ), a
plurality of scan lines (e.g. G1, G2, . . . ), a data driving
circuit 102, a gamma circuit 104 and a pixel array 110, in which
the pixel array 110 is defined by intersecting the data lines D1,
D2, . . . and the scan lines G1, G2, . . . , and the gamma circuit
104 is configured for transmitting gamma signals to the data
driving circuit 102, so as to drive the pixel array 110 through the
data lines D1, D2, . . . by the data driving circuit 102, such that
the pixel array 110 displays images according to data transmitted
through the data lines D1, D2, . . . .
[0022] In the present embodiment, the pixel array 110 includes a
plurality of pixels 111, and each of the pixels 111 includes a
plurality of sub-pixels 112 which can be red, green or blue. In
addition, each sub-pixel 112 includes a first portion 112a and a
second portion 112b, and the first portion 112a and second portion
112b of the sub-pixel 112 are separately coupled to the
corresponding data lines and coupled to the corresponding scan line
together. Specifically, in FIG. 1, the first portion 112a and
second portion 112b of the sub-pixel 112 at the 1.sup.st column and
1.sup.st row are separately coupled to the corresponding data lines
D1 and D2 and also coupled to the corresponding scan line G1
together. For the sub-pixel 112 on the same row and adjacent to the
sub-pixel 112 at the 1.sup.st column and 1.sup.st row, its first
portion 112a and second portion 112b are separately coupled to the
corresponding data lines D3 and D4 and also coupled to the
corresponding scan line G1 together. For the sub-pixel 112 on the
same column and adjacent to the sub-pixel 112 at the 1.sup.st
column and 1.sup.st row, its first portion 112a and second portion
112b are separately coupled to the corresponding data lines D1 and
D2 and coupled to the corresponding scan line G2 together. The rest
of sub-pixels 112 may be deduced by analogy. Therefore, it can be
seen that each sub-pixel 112 is coupled to two data lines and one
scan line. Moreover, in one embodiment, a ratio of the size of the
first portion 112a to the size of the second portion 112b is
approximately 1:1. However, persons skilled in the art can adjust
the ratio in practice.
[0023] When the 2D/3D image displaying apparatus 100 displays 2D
images, the gamma circuit 104 transmits gamma signals to the data
driving circuit 102 such that the data driving circuit 102
separately and dependently drives the first portion 112a and the
second portion 112b of each sub-pixel 112 through the data lines
D1, D2, . . . . Specifically, when 2D images are displayed, the
gamma circuit 104 transmits different gamma signals having
dependent relationships therebetween to the data driving circuit
102, such that the first portion 112a and the second portion 112b
of each sub-pixel 112 are driven by the data driving circuit 102,
resulting in that the corresponding first portion 112a and second
portion 112b display images with different illumination. For
example, when the sub-pixel 112 is about to display the image
having a certain gray level, the gamma circuit 104 would transmit
different but matching gamma signals to the data driving circuit
102, such that gray-level images displayed by the first portion
112a and the second portion 112b are just matched to be the
gray-level images which the sub-pixel 112 is about to display, even
if the first portion 112a and the second portion 112b display
different gray-level images.
[0024] On the other hand, when the 2D/3D image displaying apparatus
100 displays 3D images, the gamma circuit 104 transmits gamma
signals to the data driving circuit 102 such that the data driving
circuit 102 separately and independently drives the first portion
112a and the second portion 112b of each sub-pixel 112 through the
data lines D1, D2, . . . . Specifically, when 3D images are
displayed, the gamma circuit 104 transmits a single gamma signal to
the data driving circuit 102, such that the first portion 112a and
the second portion 112b of each sub-pixel 112 are driven by the
data driving circuit 102, resulting in that the corresponding first
portion 112a and second portion 112b display different and
independent gray-level images.
[0025] The 2D/3D image displaying apparatus 100 further includes a
patterned optical phase retarder 120 which is selectively arranged
corresponding to the first portions 112a or the second portions
112b of the sub-pixels 112, so as to modulate the light passing
through the first portions 112a or the second portions 112b. In the
present embodiment, the patterned optical phase retarder 120 is
exemplarily arranged corresponding to the first portions 112a of
each row of the sub-pixels 112, as shown in FIG. 1, so as to
modulate the light passing through the first portions 112a, such
that the first portions 112a can produce different polarization
from that of the second portions 112b and display desired
images.
[0026] FIG. 2 illustrates a block diagram of the 2D/3D image
displaying apparatus according to one embodiment of the present
invention. The 2D/3D image displaying apparatus 200 includes a
splitter 202, timing controllers 204a and 204b, drivers 206a and
206b, a display panel 208 and a gamma circuit 210, in which the
display panel 208 can include the data lines, scan lines and pixel
array as shown in FIG. 1, and the timing controllers 204a and 204b
or the drivers 206a and 206b can be integrated into a single
circuit for processing signals. After receiving and distributing a
TV video signal with full high definition (FHD) and a frequency of
120 Hz, the splitter 202 transmits the processed signals to the
timing controllers 204a and 204b respectively. Then, the drivers
206a and 206b are controlled respectively by the timing controllers
204a and 204b and separately transmit data to the display panel 208
according to the processed signals received from the timing
controllers 204a and 204b and different gamma signals (or gamma
voltages) A and B transmitted from the gamma circuit 210,
respectively, such that the display panel 208 is capable of
displaying 2D images with a frequency of 120 Hz without causing
color wash-out problems.
[0027] FIG. 3 illustrates a block diagram of the 2D/3D image
displaying apparatus according to another embodiment of the present
invention. The 2D/3D image displaying apparatus 300 includes a
mixer 302, a splitter 304, timing controllers 306a and 306b,
drivers 308a and 308b, a display panel 310 and a gamma circuit 312,
in which the display panel 310 can include the data lines, scan
lines and pixel array as shown in FIG. 1, the timing controllers
306a and 306b or the drivers 308a and 308b can be integrated into a
single circuit for processing signals, and the gamma circuit 312
can be the same as the gamma circuit 210 as shown in FIG. 2. After
receiving and superimposing a left-eye and right-eye video signal
with full high definition (FHD) and a frequency of 60 Hz, the mixer
302 transmits the processed signals to the splitter 304. Then,
after receiving and distributing the signal from the mixer 302, the
splitter 304 transmits the processed signals to the timing
controllers 306a and 306b respectively. After that, the drivers
308a and 308b are controlled respectively by the timing controllers
306a and 306b and transmit data to the display panel 310 according
to the processed signals received from the timing controllers 306a
and 306b and single gamma signal C transmitted from the gamma
circuit 312, such that the first portions and second portions of
the sub-pixels in the display panel 310 are capable of respectively
displaying left-eye and right-eye 3D images with frequency of 60
Hz, for users wearing polarized glasses to view the 3D images
displayed on the display panel 310, without causing resolution of
3D images to deteriorate.
[0028] FIG. 3A illustrates the switch of gamma signals outputted by
the gamma circuit operating under 2D and 3D image modes according
to one embodiment of the present invention. As shown in FIG. 3A,
when the gamma circuit operates under the 2D image mode, the gamma
circuit outputs different gamma signals A and B having dependent
relationships therebetween, such that the driving circuit can
separately drive the first portions 112a and the second portions
112b of the sub-pixels 112 according to the different gamma signals
A and B, and the first portions 112a and the second portions 112b
of the sub-pixels 112 display the images corresponding to the gamma
signals A and B having dependent relationships therebetween, to
solve color wash-out problems. The gamma signal D represented by
the dotted line is equivalent to the ultimately outputted gamma
signal (corresponding to the gray-level image on the display screen
and viewed by human eyes) after the gamma signals A and B are
superimposed. On the contrary, when the gamma circuit operates
under the 3D image mode, the gamma circuit outputs single gamma
signal C, such that the driving circuit can separately drive the
first portions 112a and the second portions 112b of the sub-pixels
112 according to the gamma signal C, and the first portions 112a
and the second portions 112b of the sub-pixels 112 separately
display different and independent images according to the gamma
signal C, to prevent from deteriorating resolution of 3D
images.
[0029] In other words, when the display device operates under 2D
and 3D image mode respectively, the switch between 2D and 3D image
modes can be performed by using a programmable gamma circuit or
gamma IC to transmit required gamma signals corresponding to 2D or
3D images to the driving circuit, for the display device to display
2D or 3D images.
[0030] On the other hand, for the timing controllers shown in FIGS.
2 and 3, they transmit timing control signals with different
frequencies to the driving circuit when 2D and 3D images are
displayed respectively, so as to control the driving circuit. In
one embodiment, the frequency of the timing control signal
transmitted by the timing controller when the 2D image is displayed
is larger than the frequency of the timing control signal
transmitted when the 3D image is displayed. Taking the embodiments
in FIGS. 2 and 3 for example, the timing control signal transmitted
by the timing controller when the 2D image is displayed is two
times the frequency of the timing control signal transmitted when
the 3D image is displayed. As a result, the displaying apparatus
can separately display 2D images with frequency of 120 Hz or 3D
images with frequency of 60 Hz by being switched to operate with
different frequencies.
[0031] Moreover, in another embodiment, the foregoing splitter 304
further can transmit the processed signals to the timing
controllers 306a and 306b respectively for follow-up process after
distributing one multi-view image signal, such that the first
portions and the second portions of the sub-pixels in the display
panel 310 separately display the corresponding portions of the
multi-view image, for viewers with naked eyes to view the displayed
3D images on the display panel 310. Therefore, the foregoing
embodiments in FIGS. 2 and 3 are employed with different data
streaming manners to respectively transmit different frame data to
different regions of each sub-pixel, to further achieve the effect
of enhancing resolution of images.
[0032] Thus, when the 2D/3D image displaying apparatus in the
embodiment of the present invention has the display panel shown in
FIG. 1, the 2D/3D image displaying apparatus can include the
circuits shown in FIGS. 2 and 3 and can switch when displaying 2D
or 3D image, so as to process the 2D or 3D image data.
[0033] FIG. 4 illustrates a pixel array according to another
embodiment of the present invention. Compared to FIG. 1, the pixel
array 410 includes a plurality of pixels 411, each of which further
includes a plurality of sub-pixels 412, and each sub-pixel 412
includes a first portion 412a and a second portion 412b, in which a
ratio of the size of the first portion 412a to the size of the
second portion 412b can be approximately 1:1, in which persons
skilled in the art can adjust the ratio in practice, and the first
portion 412a and the second portion 412b can be separately coupled
to the corresponding scan lines and coupled to the corresponding
data line together.
[0034] Specifically, in FIG. 4, the first portion 412a and the
second portion 412b of the sub-pixel 412 at the 1.sup.st column and
1.sup.st row are separately coupled to the corresponding scan lines
G1 and G2 and coupled to the corresponding data line D1 together.
For the sub-pixel 412 on the same column and adjacent to the
sub-pixel 412 at the 1.sup.st column and 1.sup.st row, its first
portion 412a and second portion 412b are separately coupled to the
corresponding scan lines G3 and G4 and also coupled to the
corresponding data line D1 together. For the sub-pixel 412 on the
same row and adjacent to the sub-pixel 412 at the 1.sup.st column
and 1.sup.st row, its first portion 412a and second portion 412b
are separately coupled to the corresponding scan lines G1 and G2
and coupled to the corresponding data line D2 together. The rest of
sub-pixels 412 may be deduced by analogy. Therefore, it can be seen
that each sub-pixel 412 is coupled to two scan lines and one data
line.
[0035] As a result, the first portions 412a and the second portions
412b in the pixel array 410 also can be analogous to the first
portions 112a and the second portions 112b in FIG. 1 and display
corresponding 2D or 3D images according to the driving circuit and
its operations. Similarly, the 2D/3D image displaying apparatus 400
can further include a patterned optical phase retarder (not shown)
which is selectively arranged corresponding to the first portions
412a or the second portions 412b of the sub-pixels 412, so as to
modulate the light passing through the first portions 412a or the
second portions 412b.
[0036] Based on the concepts in FIGS. 1 and 4, a single sub-pixel
further can be designed to include a plurality of portions. FIG. 5
illustrates a single sub-pixel according to yet another embodiment
of the present invention. The sub-pixel 512 can be red, green or
blue. Compared to the sub-pixel in FIGS. 1 and 4, the sub-pixel 512
in the present embodiment includes a plurality of portions 516
which are defined by intersecting a plurality of (e.g. M) data
lines and a plurality of (e.g. N) scan lines; that is, each
sub-pixel 512 is coupled to M data lines and N scan lines and has a
plurality of portions 516, and the sizes of the portions 516 can
all be approximately the same.
[0037] Notably, although the multiple portions of the sub-pixel
shown in FIGS. 1, 4 and 5 are exemplarily illustrated as
quadrangles, they can be designed as triangles or other shapes in
practice by persons skilled in the art and not limited to the
shapes illustrated in FIGS. 1, 4 and 5.
[0038] For the foregoing embodiments of the present invention, the
2D/3D image displaying apparatus can be employed to not only
improve the color wash-out when the displaying apparatus displays
2D images but also enhance resolution of 3D images displayed on the
displaying apparatus when the displaying apparatus displays 3D
images.
[0039] As is understood by a person skilled in the art, the
foregoing embodiments of the present invention are illustrative of
the present invention rather than limiting of the present
invention. It is intended to cover various modifications and
similar arrangements included within the spirit and scope of the
appended claims, the scope of which should be accorded the broadest
interpretation so as to encompass all such modifications and
similar structures.
