A kind of touch sensor and its manufacturing method, touch display panel

Abstract

The present invention provides a touch sensor, a manufacturing method thereof, and a touch display panel, comprising: a base material, the base material includes a plurality of grooves, the plurality of grooves are strip-shaped, and the grooves intersect to form a grid; the first The wettability adjustment layer, the first wettability adjustment layer is arranged on the inner wall surface of the groove; the touch electrode, the touch electrode fills the groove, the first wettability adjustment layer is located between the groove and the touch electrode; the touch electrode In the solution state, the wetting angle with the first wettability adjustment layer is α, and the wetting angle between the touch electrode and the substrate in the solution state is β, wherein α and β are not equal; the formation of the touch electrode in the present invention can realize Better control reduces the difficulty of making the touch electrodes, enhances the process stability of the touch electrodes, and makes the touch electrodes evenly spread in the groove, greatly reducing the possibility of disconnection of the touch electrodes, thus improving the touch The touch reliability of the control electrode.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a touch sensor, a manufacturing method thereof, and a touch display panel. Background technique [0002] At present, in order to realize the touch function of the flexible display panel using organic light-emitting diodes, it is usually necessary to attach a layer of touch film on the basis of the display panel, so that the flexible display panel cannot be thinned. In order to realize the thinning and thinning of touch-sensitive flexible display panels, integration technology is used to replace the traditional film assembly technology. The current integration technology mainly includes the following two types: [0003] One is to integrate the touch electrodes into the protective film, polarizer or glass cover. Although this method reduces the thickness of flexible display products to a certain extent, it requires more production of the protective film, polarizer and gl...

Problems solved by technology

[0003] One is to integrate the touch electrodes into the protective film, polarizer or glass cover. Although this method reduces the thickness of flexible display products to a certain extent, it requires more production of the protective film, polarizer and glass cover. high

[0004] The second is to integrate the touch electrodes on the surface of the thin film encapsulation layer. The touch electrodes need to undergo photolithography and wet etching processes, but the yellow light effect of the photolithography process will damage the light-emitting layer of the organic light-emitting display panel. The acidic or alkaline chemical solution in the process is easy to damage the film layers in the thin film encapsulation layer
