Flexible touch sensor and flexible touch display panel

Abstract

The invention provides a flexible touch sensor. The flexible touch sensor comprises a plurality of first touch electrodes and a plurality of second touch electrodes, a folding region and a non-folding region, a third touch electrode and an insulating layer; the third touch electrode is arranged in the folding region, and the first touch electrodes are arranged in the non-folding region; the third touch electrode does not overlap with the parts of the second touch electrodes on the folding region; the insulating layer is arranged in the non-folding region, and the first touch electrodes and the second touch electrodes are insulated through the insulating layer. According to the flexible touch sensor and a flexible touch display panel, the folding region and the non-folding region are arranged, the insulating layer is only arranged in the non-folding region, a stacking film layer of the folding area is thinned, and the folding region is not provided with the insulating layer where cracks are easily generated; the stability of the bending performance of the folding region is enhanced, and therefore it is ensured that the flexible touch sensor has good touch performance after repeated bending.

Description

technical field [0001] The invention relates to the display field, in particular to a flexible touch sensor and a flexible touch display panel. Background technique [0002] As an input medium, the touch screen is currently the simplest, most convenient and natural way of human-computer interaction. Integrating a touch function on a display device has become a research and development hotspot of more and more flat panel display manufacturers. [0003] With the development of flexible display technology, more flexible display panels with touch functions are developed and used. Since flexible display panels can be bent, folded or even rolled, this requires touch sensors to have flexible characteristics. When the flexible touch sensor in the prior art is bent, folded and curled, film cracks, film breakage and film separation are likely to occur in the folded area, resulting in failure of the touch function of the touch sensor. Contents of the invention [0004] In view of t...

[0003] With the development of flexible display technology, more flexible display panels with touch functions are developed and used. Since flexible display panels can be bent, folded or even rolled, this requires touch sensors to have flexible characteristics. When the flexible touch sensor in the prior art is bent, folded and curled, it is easy to have film cracks, film breakage and film separation in the folded area, which leads to the failure of the touch function of the touch sensor.
