Display substrate and display device

Abstract

The invention discloses a display substrate and a display device. At least part of support columns of the display substrate are arranged in black matrix areas, each black matrix area is located between red pixels in every two adjacent rows of pixels and a same column of pixels, the width of black matrixes in the areas where the support columns are located is increased, and therefore compared with the prior art, the phenomenon that the blue points are bad due to the fact that the support columns are arranged in the black matrix areas corresponding to blue pixels can be effectively improved; through chromaticity simulation, it can be known that on the condition that the normal color temperature conditions are met, the influence of red pixel opening ratio decreasing on the color temperature is the least, therefore, the width of the black matrixes corresponding to red pixels can be increased, that is, the opening ratio of the red pixels can be decreased on the condition that the normal color temperature conditions are met. Accordingly, by arranging the support columns in the black matrix areas corresponding to the red pixels and correspondingly increasing the width of the black matrixes in the corresponding areas, the problem that the blue points of the display substrate are bad can be solved, and meanwhile the product with the better color displaying quality can be obtained.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate and a display device. Background technique [0002] In the prior art, such as figure 1 As shown, we generally set the support column P on the black matrix area M corresponding to the blue pixel B in two adjacent rows of pixels. Therefore, disposing the supporting pillars in this area will cause the phenomenon of blue dot defect on the display panel. In order to improve the blue dot problem mentioned above, the relevant technicians generally widen the width of the black matrix in the area occupied by the supporting pillars, but this will reduce the aperture ratio of the blue pixels, which will lead to an increase in the color temperature of the display panel. However, when the color temperature is relatively high, the picture displayed on the display panel will appear bluish. [0003] Therefore, how to improve the problems of poor blue point and hig...
