Liquid crystal display realizes colored display using addition colour mixture, i.e., R (red is red), G (green green), B
(blue blue) three primary colors restore other various colorss after being directly superimposed mixing.Design for liquid crystal display, color taste
It is the critically important design factor of item, specifically can is in by ClE1931 chromaticity coordinates (chromaticity coordinate)
It is existing.So-called ClE1931 chromaticity coordinates is that color can be described by plane space, and by three primary colors RGB stimulation value
(Tristimulus Values) X, Y, Z is converted into chromaticity coordinates, and conversion formula is as follows:
X=X/ (X+Y+Z) y=Y/ (X+Y+Z) z=Z/ (X+Y+Z)=1-x-y

How a kind of liquid crystal display is provided, and the color dot coordinate of the adjustable white light deviateed is to improve the partially yellow problem of white light, actually
The important topic of those skilled in the art.
Below with reference to the accompanying drawings the invention will be further described with optional embodiment.
As shown in Figures 1 to 6, the embodiment of the present invention discloses a kind of display panel, including the first sub-pixel 111, second
Sub-pixel 112 and third sub-pixel 113 all include: common line 114；The pixel electrode 115 being formed in above the common line；
The storage capacitors 116 formed by the pixel electrode 115 and 114 lap of the common line；The third sub-pixel 113
Storage capacitors 116 are less than the storage capacitors 116 of first sub-pixel 111 and second sub-pixel 112；The third picture
The corresponding blue of element 113.
Its smaller corresponding sub-pixel charge rate of storage capacitors 116 will be bigger, makes the storage of the third sub-pixel 113
Capacitor 116 is less than the storage capacitors 116 of first and second sub-pixel 112, then the charge rate of third sub-pixel 113 is with respect to the
One and second sub-pixel 112 charge rate improve, improve third sub-pixel 113 luminance gain, improve display panel white light
Yellow problem partially.
In one embodiment, the overlapping area of the pixel electrode 115 of the third sub-pixel 113 and the common line 114
Corresponding pixel electrode 115 less than first sub-pixel 111 and second sub-pixel 112 is overlapping with common line 114
Area.
The size of storage capacitors 116 depends on the overlapping area size of common line 114 and pixel electrode 115, overlapping area
Smaller storage capacitors 116 are smaller, its smaller corresponding sub-pixel charge rate of storage capacitors 116 will be bigger, and storage capacitors 116 are got over
Small, the current potential that corresponding sub-pixel is filled is also higher, and charge rate is also bigger, thus opposite to improve third sub-pixel 113
Charge rate, make third sub-pixel 113 luminance gain be higher than the first sub-pixel 111 and the second sub-pixel 112 luminance gain.
First sub-pixel 111, the second sub-pixel 112 and corresponding 114 shape of common line of third sub-pixel 113 and line
It is wide consistent；The area of the pixel electrode 115 of the third sub-pixel 113 is less than first sub-pixel 111 and second son
The area of the corresponding pixel electrode 115 of pixel 112.
If changing simultaneously common line 114 and pixel electrode 115, compared to only changing, one such meeting is comparatively laborious, and
The material of pixel electrode 115 is usually plastics, and shape is a monolith, and the material of common line 114 is metal, and shape is to hand in length and breadth
Wrong, so the area that the area ratio for changing pixel electrode 115 changes common line 114 wants easier, the picture of third sub-pixel 113
The area of plain electrode 115 is less than the area of the pixel electrode 115 of first sub-pixel 111 and second sub-pixel 112, can
So that the charge rate of third sub-pixel 113 is greater than the charge rate of the first, second sub-pixel 112, the bright of third sub-pixel 113 is improved
Spend gain.
The area of the pixel electrode 115 of first sub-pixel 111 and second sub-pixel 112 is equal to third
The area of the corresponding pixel electrode 115 of pixel 113, the line width of the common line 114 of the third sub-pixel 113 is than first son
Pixel 111, the line width of the corresponding common line 114 of the second sub-pixel 112 are small.
The size of storage capacitors 116 depends on the overlapping area size of common line 114 and pixel electrode 115, overlapping area
Smaller storage capacitors 116 are smaller, reduce the line width of 113 common line 114 of third sub-pixel to reduce the storage of third sub-pixel 113
Capacitor 116 can not only improve the charge rate of third sub-pixel 113 since the line width of common line 114 becomes smaller in this way, improve white
The partially yellow problem of light can also increase the aperture opening ratio of display panel, improve display effect.
In one embodiment, as shown in figure 3, the common line includes the first common line 117, the second common line 118 and the
The shape of three common lines 119, first common line 117, the second common line 118 and third common line 119 is all rectangle, institute
It states the first common line 117 and the second common line 118 is arranged in parallel relatively, the third common line 119 and first common line
117 and second common line 118 it is vertical and intersect, the shape of the pixel electrode 115 is rectangle, 115 axis of pixel electrode
Symmetrical part overlaps in first common line 117, the second common line 118 and third common line 119, and the axis is described
The central axis of first common line 117 and 118 distance of the second common line, the first common line 117 of the third sub-pixel, the
The line width of the line width of two common lines 118 or third common line 119 common line more corresponding than first sub-pixel, the second sub-pixel
It is small.
Similar " H " type of the common wire shaped, since pixel electrode 115 is that local first common line 117, second that overlaps is total to
On logical line 118 and third common line 119, third common line 119 and the first common line 117 and the second common line 118 are vertical simultaneously
Intersection, the wide of the first and second common lines 118 has part not Chong Die with pixel electrode 115, so needing to reduce first and second
The width of common line 118 and 115 lap of pixel electrode could reduce the storage capacitors 116 of third sub-pixel, and third is total
The wide and pixel electrode 115 of logical line 119 is completely overlapped, so the width of third common line 119 no matter how is reduced, it can
Improve the charge rate of third sub-pixel.
In one embodiment, the common line includes the first common line 117, the second common line 118 and third common line
119, the shape of first common line 117, the second common line 118 and third common line 119 is all rectangle, and described first is total
Logical line 117 and the second common line 118 are arranged in parallel relatively, the third common line 119 and first common line 117 and second
Common line 118 is vertical and intersects, and the shape of the pixel electrode 115 is rectangle, the axisymmetric part of the pixel electrode 115
It overlaps in first common line 117, the second common line 118 and third common line 119, the axis is first common line
117 are less than described with the central axis of 118 distance of the second common line, the area of the pixel electrode 115 of the third sub-pixel
The area of first sub-pixel and the corresponding pixel electrode 115 of second sub-pixel.
Since pixel electrode 115 is that overlap first common line 117, the second common line 118 and third common for part
Among line 119, and pixel electrode 115 is not in hollow out under normal circumstances, so howsoever reducing third picture
The area of the pixel electrode 115 of element, can all reduce the area of the lap between pixel electrode 115 and common line, to drop
The storage capacitors 116 of low third sub-pixel promote the charge rate of third sub-pixel.
In one embodiment, as shown in Figure 4 and Figure 5, the common line includes the first common line 117, the second common line
118, third common line 119 and the 4th common line 1110, first common line 117, the second common line 118, third common line
119 and the 4th the shape of common line 1110 be all rectangle, first common line 117 and the second common line 118 are relatively parallel
Setting, the third common line 119, the 4th common line 1110 are arranged in parallel relatively, the third common line 119 and described first
Common line 117 and 118 middle section of the second common line are vertical and intersect, the end and described first of the 4th common line 1110
The end vertical of common line 117 and the second common line 118 and intersection, the shape of the pixel electrode 115 are rectangle, the picture
The axisymmetric part of plain electrode 115 overlaps first common line 117, the second common line 118, third common line 119 and
In four common lines 1110, the axis is the central axis of first common line 117 and 118 distance of the second common line, described
The line width ratio of first common line 117 of third sub-pixel, the second common line 118, third common line 119 or the 4th common line 1110
First sub-pixel, the line width of the corresponding common line of the second sub-pixel are small.
Since pixel electrode 115 is that part overlaps the first common line 117, the second common line 118, third common line 119
In the 4th common line 1110, the end vertical of the 4th common line 1110 and the first common line 117 and the second common line 118 is simultaneously
Intersection, first, second and the 4th the wide of common line 1110 have part not Chong Die with pixel electrode 115, so needing to reduce the
One, second and the 4th common line 1110 and 115 lap of pixel electrode width, the storage that could reduce third sub-pixel is electric
Hold 116, and the wide and pixel electrode 115 of third common line 119 is completely overlapped, so no matter how reducing third common line
