Array substrate, preparing method thereof, display panel and display device

Abstract

The invention relates to the technical field of display, and discloses an array substrate, a preparing method thereof, a display panel and a display device. The array substrate comprises a substrate body, a plurality of grid wires and a plurality of touch control electrode wires, wherein a plurality of pixels are arranged in a pixel area of the substrate body in arrays, the grid wires extend on the substrate body in the first direction of the pixel arrays, the touch control electrode wires extend on the substrate body in the first direction of the pixel arrays and are insulated from the grid wires, and the positive projection of the touch control electrode wires on the substrate body and the positive projection of the grid wires on the substrate body are at least partly overlapped. Compared with similar array substrates in the prior art, the array substrate has the advantages that the display area occupied by signals wires is small, the opening rate of the pixels is large, the short-circuit situation between the touch control electrode wires and the data wires cannot easily happen, the opening rate of the array substrate is high, and the x-line failures can be avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a preparation method thereof, a display panel, and a display device. Background technique [0002] Products with full in-cell touch structure (FIC, Full in Cell), high pixel (PPI), and high aperture ratio are the main development direction of low temperature polysilicon liquid crystal display panel (LTPS LCD). However, with the increase of PPI, The existing Fullin Cell LCD product design will inevitably face the dilemma of insufficient aperture ratio; specifically, in the existing panel design, the data line (Date signal line) and the touch electrode line (TPM signal line) are arranged on the same layer , and the signal line uses Ti / AL / Ti light-shielding material, which leads to a great reduction in the aperture ratio of existing products; at the same time, due to the small distance between the Date signal line and the TPM signal line, it is often ...

However, with the increase of PPI, The existing Fullin Cell LCD product design will inevitably face the dilemma of insufficient aperture ratio; specifically, in the existing panel design, the data line (Date signal line) and the touch electrode line (TPM signal line) are arranged on the same layer , and the signal line uses Ti / AL / Ti light-shielding material, which leads to a great reduction in the aperture ratio of existing products; at the same time, due to the small distance between the Date signal line and the TPM signal line, it is often due to the remaining material (remain ) or particles cause a short circuit, which leads to the voltage of the Date signal line being pulled down during driving, so that the Data signal line cannot drive the pixels normally, resulting in a bad x-line
