Abstract

Disclosed is a method for preparing a drive substrate. The method comprises: obtaining a first thickness value of a first dielectric layer based on a difference value between the load of all first storage capacitors in a special-shaped display drive region and the load of all second storage capacitors in a normal display drive region; providing a base, and depositing a first metal layer on a surface of the base; and controlling a film forming process parameter by means of a film thickness control model, and depositing the first dielectric layer and a second dielectric layer on a surface of the first metal layer such that the thickness of the first dielectric layer reaches the first thickness value, and the thickness of the second dielectric layer reaches a second thickness value, the first thickness value being less than the second thickness value. Further disclosed are a drive substrate and a display apparatus.

Description

technical field

[0001] The present application relates to the display field, in particular to a method for preparing a driving substrate. Background technique

[0002] With the continuous development of the mobile phone industry, the screen body of a full-screen mobile phone has the advantages of a large screen-to-body ratio and a narrow frame, which greatly improves the visual effect of the viewer and has attracted widespread attention.

[0003] In the production process of the full screen, the special-shaped display area is usually formed by special-shaped designs such as slots on the screen body. The number of pixels at the slot is less than the number of pixels in the normal display area. Therefore, the load of the pixel driving signal in the special-shaped display area is very different from that of the normal display area, resulting in different RC delays of driving signals such as pixel scanning, resulting in different brightness between the special-shaped display ar...
