Problems solved by technology

[0004] However, the driving method of the existing touch display panel to realize pressure sensing is relatively complicated. In a period of time, it is necessary to first obtain the signal amount of touch sensing, and then obtain the total signal amount of touch sensing and pressure sensing, and then obtain the total signal amount of touch sensing and pressure sensing. Through algorithm processing, indirectly obtain the semaphore of pressure sensing detection
It can be seen that this driving method cannot directly receive the semaphore of pressure detection, and the effect of pressure detection is not good.

Abstract

The invention discloses a touch display panel and a driving method thereof and a touch display device. The touch display panel comprises a first substrate, multiple grate signal wires arranged on the first substrate and reused as grate scanning wires and pressure driving wires when the grate signal wires are divided, a pressure testing layer used for receiving pressure testing signals when the grate signal wires are configured as the pressure driving wires so that pressure magnitude can be detected according to capacitance changes between the grate signal wires and the pressure testing wires. The touch display panel has a pressure testing function so that detection of external pressure by the touch display panel can be achieved. The touch display panel and the driving method thereof can directly obtain signal amount of pressure testing and optimize pressure testing effect.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel, a driving method for the touch display panel, and a touch display device with the touch display panel. Background technique [0002] With the rapid development of display technology, touch display panels have gradually spread in people's lives. Especially with the emergence of the pressure sensing technology, the touch display panel can sense the strength of light pressure and heavy pressure, and call out different corresponding functions, so that the touch display panel has more applicability. [0003] In the existing touch display panel, in order to realize the function of pressure sensing, a plurality of first common electrodes disposed on the array substrate are usually used, and the first common electrodes are multiplexed as touch electrodes and pressure sensing electrodes. That is, during the touch sensing period, the first common electrode ...
