Display substrate and preparing method thereof and display panel

Abstract

The invention provides a display substrate and a preparing method thereof and a display panel, and relates to the technical field of displaying. The quantity of mask plates in the display substrate preparing process can be decreased. The preparing method includes the steps that a plurality of first shading strips and a plurality of second shading strips intersecting with the first shading strips are formed on a substrate to obtain a black matrix pattern; a plurality of first touch electrode strips are formed on the substrate, wherein orthogonal projection of the first touch electrode strips and orthogonal projection of the first shading strips are overlapped on the substrate; a first insulating layer covering the multiple first touch electrode strips is formed on the substrate; a plurality of second touch electrode strips are formed on the substrate, wherein orthogonal projection of the second touch electrode strips and orthogonal projection of the second shading strips are overlapped on the substrate; a second insulating layer covering the multiple second touch electrode strips is formed on the substrate; the multiple first shading strips and the multiple first touch electrode strips are exposed and obtained through first mask plates; the multiple second shading strips and the multiple second touch electrode strips are exposed and obtained through second mask plates.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a preparation method thereof, and a display panel. Background technique [0002] With the development of touch technology, touch display screens have penetrated into people's work and life. After Apple proposed and used in cell touch (embedded touch) technology, various brand manufacturers have also used in cell touch technology, and in cell touch technology has gradually entered the use of TPC (touch personal computer) products from Mobile (mobile phone), and even NB (Notebook, referred to as notebook computer) products are also beginning to be used in small batches. It can be seen that integrating the touch function into the display panel is an inevitable trend, and it is also a manifestation of a company's product technical capabilities. [0003] At present, the conventional in cell touch process can use ITO (indium tin oxide) or Metal mesh (metal mesh) ...

AI Technical Summary

Problems solved by technology

[0005] However, in the prior art, in the process of forming the black matrix, the touch electrode strips, and the insulating strips covering the touch electrode strips, five different mask plates are required, which is costly and is not conducive to improving the production efficiency of the production line. , and because the number of mask plates used is large, the number of times the exposure machine replaces the mask plates increases the possibility of the exposure machine being polluted by the external environment during the process of replacing the mask plates, thereby increasing the PM of the exposure machine ( Preventive Maintenance, referred to as machine adjustment) time
