Array substrate and preparation method therefor and display apparatus

Abstract

The invention provides an array substrate and a preparation method therefor and a display apparatus. The array substrate comprises an insulating layer; the insulating layer comprises a transparent part and a light shielding part; and the projection of the light shielding part on the substrate of the array substrate covers the projections of a gate line, a source, a drain and a data line on the substrate of the array substrate. Therefore, the light shielding part can replace a conventional black matrix, so that product structure can be simplified and the product thickness can be reduced; and in addition, the dimension of the light shielding part can be smaller than that of the conventional black matrix, so that aperture ratio can be improved.

Description

technical field [0001] The present invention relates to the display field, in particular, to an array substrate, a preparation method thereof, and a display device. Background technique [0002] In the edge field effect (ADS) display mode of high-pixel products or low-temperature polysilicon (LTPS), it is generally necessary to make an acrylic layer to increase the storage capacitor. Acrylic is a plastic polymer material with good permeability and easy dyeing specialty. The acrylic layer can increase the transmittance and flatness, but there are still cases where the opening ratio is insufficient. Moreover, the traditional black matrix light-blocking layer is designed on the color film substrate, and the width of the black matrix light-blocking layer is relatively wide, so that the aperture ratio of the LCD screen is small, which cannot meet the demand for high aperture ratio of high-pixel products. [0003] Therefore, the research on the aperture ratio of display devices ...

The acrylic layer can increase the transmittance and flatness, but there are still insufficient opening ratios

In addition, the traditional black matrix light-blocking layer is designed on the color film substrate, and the width of the black matrix light-blocking layer is relatively wide, so that the aperture ratio of the LCD screen is small, which cannot meet the demand for high aperture ratio of high-pixel products.

[0003] Therefore, research on the aperture ratio of display devices needs to be in-depth
