Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to the field of display
technology, and in particular to a pixel structure.
[0003] 2. The Related Arts
[0004] Tablet display devices, such as liquid crystal displays
(LCDs) and organic light emitting diode (OLED) displays, are the
main streams of today's market.
[0005] A display panel is an important constituent part of the
tablet display devices, such as LCDs and OLEDs. In a conventional
display device of LCD and OLED, the display panel comprises a
plurality of pixels arranged in an array. Each of the pixels
comprises a plurality of sub-pixels. For example, each pixel
comprises red (R), green (G), and blue (B) sub-pixels. Each pixel
display colors through color mixture. To improve visual effect,
people have placed increasingly high demand for resolution of the
display panel. This makes the size of the sub-pixels increasingly
reduced. However, the constraints of the manufacturing techniques
make it not possible to unlimitedly reduce the size of the
sub-pixels. To improve the effect of displaying under the same size
of sub-pixels, heretofore a so-call Pen Tile structure has been
proposed for the display panels.
[0006] The pen tile structure reduces the number of sub-pixels by
having sub-pixels commonly shared by adjacent pixels so that an
effect of mimicking a high resolution with a low resolution may be
achieved. In a display panel of the pen tile structure, an image to
be displayed is divided into multiple theoretic pixel units
according to the resolution of a screen and then each sub-pixel is
provided with a sampling zone. The displaying illumination of the
sub-pixel is determined by calculating the surface area of the
sampling zone and the overlapping condition of the theorectic pixel
units that are covered thereby, as well as the color component of
the sub-pixel contained in each theoretic pixel unit. In the pen
tile structure, some of the sub-pixels of a display panel are
shared so that a resolution that is higher than the actual
resolution can be achieved for visual effect.
[0007] As shown in FIG. 1, a commonly used pen tile structure
adopts a rectangular design, in which red sub-pixels (R) and blue
pixels (B) alternate each other in rows in the horizontal direction
and also in columns in the vertical direction. This arrangement,
although providing an effect of mimicking a high resolution with a
low resolution, makes the design of drive circuit (particularly,
the design of arrangement of data lines) and software
rendering.
SUMMARY OF THE INVENTION
[0008] An object of the present invention is to provide a pixel
structure, which achieves an effect of mimicking a high resolution
with a low resolution and also reduces the difficulty of designing
a drive circuit so as to help simplify the manufacturing process

lattice exhibiting a honeycomb configuration comprising honeycomb

1/2 of a surface area of one second color sub-pixel and the surface
area of each of the second color sub-pixels is identical to a
surface area of one third color sub-pixel.
[0015] Each of the first color sub-pixels and three other
sub-pixels that are arranged with the first color sub-pixel as a
center and are spaced from the first color sub-pixel by a distance
a in different directions of edges of a hexagon collectively form a
pixel.

of a known pen tile structure;
[0033] FIG. 2 is a schematic view illustrating a pixel structure

[0034] FIG. 3 is a schematic view illustrating an arrangement of

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0035] To further expound the technical solution adopted in the
present invention and the advantages thereof, a detailed
description is given to a preferred embodiment of the present
invention and the attached drawings.
[0036] Referring to FIG. 2, the present invention provides a pixel
structure, which comprises a plurality of sub-pixels. The plurality
of sub-pixels is arranged in the form of a point lattice exhibiting
a honeycomb configuration comprising honeycomb cells each showing a
regular hexagon having edges that have a length a. The sub-pixels
are respectively located at vertices of the plurality of regular
hexagons.
[0037] The plurality of sub-pixels comprises a plurality of first
color sub-pixels 1, a plurality of second color sub-pixels 2, and a
plurality of third color sub-pixels 3.
[0038] For two rows of the sub-pixels that are adjacent to each
other in an up-down direction, the sub-pixels of one of the rows
are arranged in a horizontal direction such that spacing distances
therebetween are of an alternate arrangement of a and 2a, wherein
for every two sub-pixels of which the spacing distance therebetween
is a, the one of the sub-pixels that is located at the right-hand
side is a first color sub-pixel 1, while the one of the sub-pixels
that is located at the left-hand side is a second color sub-pixel
2; and, the sub-pixels of the other one of the rows are arranged in
a horizontal direction such that spacing distances therebetween are
of an alternate arrangement of 2a and a, wherein for every two
sub-pixels of which the spacing distance therebetween is a, the one
of the sub-pixels that is located at the right-hand side is a first
color sub-pixel 1, while the one of the sub-pixels that is located
at the left-hand side is a third color sub-pixel 3.
[0039] For each column of the sub-pixels, multiple ones of the
sub-pixels having the same color are arranged in a straight line in
a vertical direction, while two columns that are adjacent to each
other in a left-right direction comprise sub-pixels of different
colors.
[0040] Further, a sub-pixel column that is formed of multiple first
color sub-pixels 1 arranged in the vertical direction, a sub-pixel
column that is formed of multiple second color sub-pixels 2
arranged in the vertical direction, a sub-pixel column that is
formed of multiple first color sub-pixels 1 arranged in the
vertical direction, and a sub-pixel column that is formed of
multiple third color sub-pixels 3 arranged in the vertical
direction are arranged, in such an order, from left to right. Since
the sub-pixels that are located in the same column have the same
color and are arranged in a straight line in the vertical
direction, it is possible to design a data line for a column of the
sub-pixels for driving purpose so that, compared to the known
rectangular pen tile structure, the difficulty of designing a drive
circuit can be reduced thereby helping simplify the manufacturing
process and lower down costs.
[0041] The first color sub-pixels 1 each have a surface area that
is one half (1/2) of a surface area of one second color sub-pixels
2 and the surface area of each of the second color sub-pixels 2 is
identical to a surface area of one third color sub-pixel 3.
[0042] A pixel is formed of a first color sub-pixel 1 and three
other sub-pixels that are arranged with the first color sub-pixel 1
as a center and are spaced from the first color sub-pixels 1 by a
distance a in different directions along the edges of the hexagon.
As shown in FIG. 2, the pixel 112 is formed of one of the first
color sub-pixels 1 and one of the second color sub-pixels 2 and two
of the third color sub-pixels 3 that are arranged with said one of
the first color sub-pixels 1 as a center and are spaced from said
one of the first color sub-pixels 1 by a distance a in different
directions of the edges of the hexagon; and the pixel 121 is formed
of one of the first color sub-pixels 1 and two of the second color
sub-pixels 2 and one of the third color sub-pixels 3 that re
arranged with said one of the first color sub-pixels 1 as a center
and are spaced from said one of the first color sub-pixels 1 by a
distance a in different directions of the edges of the hexagon. The
structure that each honeycomb cell is of a regular hexagon makes
each of the second color sub-pixels 2 shared by three pixels and
each of the third color sub-pixels 3 shared by three pixels, so as
to provide, visually, a resolution higher than the actual
resolution thereby achieving an effect of mimicking a high
resolution with a low resolution.
[0043] Specifically, the first color sub-pixel 1, the second color
sub-pixel 2, the third color sub-pixel 3 can be any one of various
combinations and permutations of a red sub-pixel, a green
sub-pixel, and a blue sub-pixel. Preferably, the first color
sub-pixel 1 is a green sub-pixel; the second color sub-pixel 2 is a
red sub-pixel; and the third color sub-pixel 3 is a blue sub-pixel.
As reflected in FIG. 2, each of the pixels 112 that is centered at
each of even-column green sub-pixels shows a ratio of 1:1:2 among
the numbers of the green sub-pixels, the red sub-pixels, and the
blue sub-pixels; and each of the pixels 121 that is centered at
each of odd-column green sub-pixels shows a ratio of 1:2:1 among
the numbers of the green sub-pixels, the red sub-pixels, and the
blue sub-pixels.
[0044] It is noted here that when each of the pixels 112 centered
at each of the even-column green sub-pixels, which is the pixel
that shows the ratio of 1:1:2 among the numbers of the green
sub-pixels, the red sub-pixels, and the blue sub-pixels, display
white color, the green sub-pixels and the red sub-pixels show
brightness that is set at 100%, while the blue sub-pixels show
brightness that is set at 50%; and when each of the pixels 121
centered at each of the odd-column green sub-pixels, which is the
pixel that shows the ratio of 1:2:1 among the numbers of the green
sub-pixels, the red sub-pixels, and the blue sub-pixels, display
white color, the green sub-pixels and the blue sub-pixels show
brightness that is set at 100%, while the red sub-pixels show
brightness that is set at 50%.
[0045] As shown in FIG. 3, to accommodate the pixel structure
according to the present invention, multiple scan lines 10 that are
respectively connected to the rows of the sub-pixels are arranged
from top to bottom with identical spacing distances therebetween
and multiple data lines 20 that are respectively connected to the
columns of the sub-pixels are arranged from left to right with
alternate spacing distances of a/2 and a therebetween. In other
words, a data line is provided for each column of the sub-pixels
for driving so that the design difficulty of the drive circuit can
be reduced.
[0046] The pixel structure according to the present invention can
be expanded to sub-pixels of four different colors in an alternate
arrangement.
[0047] In summary, the present invention provides a pixel
structure, which comprises a plurality of sub-pixels arranged in
the form of a point lattice exhibiting a honeycomb configuration
comprising honeycomb cells each showing a regular hexagon having
edges that have a length a; for two rows of the sub-pixels that are
adjacent to each other in an up-down direction, the sub-pixels of
one of the rows are arranged in a horizontal direction such that
spacing distances therebetween are of an alternate arrangement of a
and 2a, wherein for every two sub-pixels of which the spacing
distance therebetween is a, the one of the sub-pixels that is
located at the right-hand side is a first color sub-pixel, while
the one of the sub-pixels that is located at the left-hand side is
a second color sub-pixel; and, the sub-pixels of the other one of
the rows are arranged in a horizontal direction such that spacing
distances therebetween are of an alternate arrangement of 2a and a,
wherein for every two sub-pixels of which the spacing distance
therebetween is a, the one of the sub-pixels that is located at the
right-hand side is a first color sub-pixel, while the one of the
sub-pixels that is located at the left-hand side is a third color
sub-pixel; for each column of the sub-pixels, multiple ones of the
sub-pixels having the same color are arranged in a straight line in
a vertical direction. Such a pixel structure achieves an effect of
mimicking a high resolution with a low resolution and also reduces
the design difficulty of a drive circuit thereby helping simplify
the manufacturing process and lower down costs.
[0048] Based on the description given above, those having ordinary
skills of the art may easily contemplate various changes and
modifications of the technical solution and technical ideas of the
present invention and all these changes and modifications are
considered within the protection scope of right for the present
invention.
