Array substrate and manufacturing method thereof and touch screen

Abstract

The invention provides an array substrate and a manufacturing method thereof and a touch screen. The array substrate comprises a touch electrode layer, a first protective layer and a filling layer, all of which are sequentially arranged from top to bottom, wherein the touch electrode layer is provided with hollowed-out parts which correspond to sub pixel units in position; one part of the hollowed-out parts and gaps form special-shaped hollowed-out parts; the filling layer corresponds to the special-shaped hollowed-out parts in position, and the filling layer and the special-shaped hollowed-out parts overlap partially so that the shapes of the portions, not overlapping with the filling layer, of the special-shaped hollowed-out parts are consistent with the shapes of the hollowed-out parts; the first protective layer is provided with first open holes, and first connection parts are arranged in the first open holes and used for connecting the touch electrode layer with the filling layer. The array substrate can overcome the defect that black stripes appear on a display panel under the condition that a module displays a gray-scale picture.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to an array substrate, a manufacturing method thereof, and a touch screen. Background technique [0002] In the existing manufacturing process of TFT-LCD products, whether it is HIC or FIC mutual capacitive touch screen, when performing time-sharing driving, the ITO layer as the common electrode is used to transmit public signals and touch signals respectively. Products (embedded touch panel) as an example, such as figure 1 As shown, the common electrode arranged inside the touch panel doubles as the transmitting electrode (Tx) 1. After the box is formed, the receiving electrode (Rx) 2 is made on the back of the color filter substrate, wherein the transmitting electrode 1 and the receiving electrode 2 The patterns are all strips and perpendicular to each other. [0003] Such as figure 1 As shown, the ITO layer of the above-mentioned emitter electrode 1 is provided with ...

AI Technical Summary

Problems solved by technology

Since the shape and size of the special-shaped hollow part are different from those of the hollow part 11, there is a difference between the electric field and the transmittance formed at the special-shaped hollow part and the hollow part 11, resulting in In the grayscale screen, black stripes and other defects appear on the display panel.
