The Crack cause of color side problem is: in display panel, usually that there are three types of different colours sub-pixels is (including red for tool
Sub-pixels, green sub-pixels and blue subpixels), arrangement of subpixels is covered with display area；For the sub- picture of most of position
For element, they can cooperate with the sub-pixel of the other colors in periphery, show required particular color；However, for position
For the most marginal sub-pixel in display area, since at least side other than them is there is no other sub-pixels, when
In multiple sub-pixels on the outermost side, continuous three or more sub-pixels can not include red sub-pixel, green simultaneously
When pixel and blue subpixels, that is, it will appear color Bian Xianxiang.
For this purpose, the present invention is for K continuous sub-pixels not simultaneously comprising red sub-pixel, green sub-pixels and the sub- picture of blue
Element, and when difference the case where all blue subpixels, these K continuous sub-pixels for being located at outmost turns are defined as the first son
Pixel, and most of normal sub-pixel is defined as the 6th sub-pixel.When first sub-pixel includes the first red sub-pixel
When, the maximum brightness of first red sub-pixel is the first red luma；The maximum brightness of 6th red sub-pixel is
6th red luma；First red luma is less than the 6th red luma；When first sub-pixel includes first green
When sub-pixels, the maximum brightness of first green sub-pixels is the first Green brightness；6th green sub-pixels are most
Big brightness is the 6th Green brightness；First Green brightness is less than the 6th Green brightness.Since first red is bright
Degree is less than the 6th red luma, and first Green brightness is less than the 6th Green brightness, therefore, is located at outermost edge
The first sub-pixel luminence that color side problem can occur reduces, and color side problem is improved.When using method of the invention, Neng Gouzhun
