Touch control sensor, flexible touch control display panel and electronic equipment

Abstract

The invention discloses a touch control sensor, a flexible touch control display panel and electronic equipment. The touch control sensor comprises a first touch control electrode layer, a substrate and a first moisture blocking layer, wherein the substrate has two opposite surfaces, and the two opposite surfaces are provided with groove structures respectively. Due to the fact that the groove structures are formed in the surfaces of the two sides of the substrate of the touch control sensor, stress which is generated when a touch control electrode is formed in the coating process and can cause curling deformation of the substrate can be effectively buffered, and the degree of curling deformation of the substrate is effectively reduced. According to the flexible touch control display panel and electronic equipment adopting the touch control sensor, due to the fact that the substrate is provided with the groove structures, substrate curling stress generated in the high-temperature film forming process can be buffered, and then the degree of curling deformation caused by height can be reduced.

Description

technical field [0001] The present invention relates to the technical field of touch devices, and more specifically, to a touch sensor, a flexible touch display panel and electronic equipment. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with touch function are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become the Indispensable and important tool. The touch panel is the main component of the electronic device to realize the touch function, and the touch sensor has become a more commonly used touch panel at the present stage due to its good touch control. [0003] refer to figure 1 , figure 1 It is a schematic structural diagram of a flexible touch display panel commonly used in the prior art. The flexible touch display panel includes: a flexible substrate 11; a first touch electrode 12 arranged on one side surface of the fl...

AI Technical Summary

Problems solved by technology

[0004] In general, the flexible substrate 11 is generally made of flexible plastic material, which has a large coefficient of thermal expansion and is easily deformed by heat.

The first touch electrodes 12 and the second touch electrodes 14 are usually made of metal or metal oxide materials, and their thermal expansion coefficients are small, and the first touch electrodes 12 and the second touch electrodes 14 require relatively high The temperature has a process of heating and cooling, and in the process of heating and cooling, it is easy to cause curling and deformation of the flexible substrate 11, which in turn leads to curling and deformation of the flexible touch display panel.
