Touch display panel and display device

Abstract

The invention relates to a touch display panel and a display device. The display panel comprises a touch electrode layer, wherein the touch electrode layer comprises multiple equal-area touch regions; each touch region comprises a touch electrode and a clearance region; a display substrate comprises sub-pixels of multiple colors; the area of sub-pixels of one color among the sub-pixels corresponding to the clearance region of each touch region is same. By virtue of setting same area of color resistance layers of each color corresponding to a slit region in the equal-area touch region, light rays emergent from the slit regions in each touch region do not generate color cast, so as to ensure that the light rays penetrating through the touch electrode layer have no color cast on the whole and further avoid the occurrence of a Newton ring phenomenon.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a touch display panel and a display device. Background technique [0002] In the existing display panel with touch function, although the touch electrode is transparent, it still has a certain influence on the light extraction rate of the display panel. There are generally gaps between the touch electrodes arranged in different directions, and there is a difference of about 10% in the light extraction rate between the gap area without touch electrodes and the area with touch electrodes, which makes the touch electrodes without touch electrodes The light output in the gap area is easily affected by the color of the sub-pixel. [0003] For example, the plane where the touch electrodes are located is divided into several areas with equal areas. The gaps in each area that are not provided with touch electrodes have the same area. If in one area, the area of ​​each color su...

[0002] In the existing display panel with touch function, although the touch electrode is transparent, it still has a certain influence on the light output rate of the display panel.

There are generally gaps between the touch electrodes arranged in different directions, and there is a difference of about 10% in the light extraction rate between the gap area without touch electrodes and the area with touch electrodes, which makes the touch electrodes without touch electrodes The light output in the gap area is easily affected by the color of the sub-pixel

[0003] For example, the plane where the touch electrodes are located is divided into several areas with equal areas. The gaps in each area that are not provided with touch electrodes have the same area. If in one area, the area of ​​each color sub-pixel corresponding to the slit The proportions are different, for example, the red sub-pixel occupies 60% of the area, and the blue sub-pixel and green sub-pixel each occupy 20% of the area, then the light emitted from this area will show rainbow patterns of different colors, thus affecting the viewing effect
