Problems solved by technology

However, the metal in the TFT area reflects light strongly, and the reflectance of the light-transmitting area is also higher than that of the CF side facing outward, resulting in a significant increase in the reflectance of the display panel to ambient light, which will reduce the image quality of the display panel.

Abstract

The invention provides an array substrate and a display panel. The array substrate comprises a substrate, a transparent insulating layer, a light absorption layer, a thin film transistor layer, a first protective layer and a color film layer. By arranging the light absorption layer in the array substrate, the problem that the reflectivity of the area where the thin film transistor layer is arranged is high is solved. Meanwhile, a whole transparent insulating layer is arranged between the substrate and the light absorption layer. According to the transparent insulating layer, on the one hand, the problem of high reflectivity of the corresponding area of the color film layer can be solved, and on the other hand, the adhesive force between the light absorption layer and the substrate can be enhanced, so the structure of the array substrate is more stable. Due to the fact that the transparent insulating layer and the light absorption layer are additionally arranged in the array substrate,the problem that a display panel emitting light from the side of the array substrate is large in reflectivity can be solved, the image quality of the display panel is improved, and the display panel can better meet the full screen requirement of the market.

Description

Technical field[0001]The present invention relates to the field of display technology, in particular to an array substrate and a display panel.Background technique[0002]Contrast is one of the important indicators for evaluating the image quality performance of liquid crystal display (LCD). In a real use scene, due to the influence of ambient light, the reflectivity of the display panel will affect the contrast of the picture, as shown below:[0003][0004]Lon / Loff Respectively indicate the brightness of the display panel in the bright state / dark state, RLIndicates the reflectivity of the display panel. Therefore, if you want to improve the contrast of the display panel, you can start from two aspects: 1. Increase the brightness of the display panel.on ; 2. Reduce the reflectivity R of the display panelL.[0005]At the same time, as the market's demand for borderless products grows, the TFT-side-out scheme is conducive to improving the module yield of four-sided borderless products.
