Abstract

The invention provides a touch display module with pressure detection. The touch display module comprises a plurality of pixel units arrange in an array manner and a three-dimensional sensor, wherein the three-dimensional sensor comprises a plurality of touch units and at least one pressure sensitive unit; the multiple pixel units receive a grid driving scanning pulse to control the grid driving scanning pulse to display a color updating time sequence; the multiple touch units receive a touch scanning pulse to control and detect a time sequence of touch points; the at least one pressure sensitive unit receives a pressure scanning pulse to control and detect a time sequence of pressure; potential switching points among the grid driving pulse, the touch scanning pulse and the pressure scanning pulse are staggered. The invention further provides a driving method of the touch display module with pressure detection. According to the method, the potential switching points among the grid driving pulse, the touch scanning pulse and the pressure scanning pulse are staggered. The touch display module with pressure detection and the driving method of the touch display module have the advantages of high anti-noise property and the like.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of touch control, in particular to a touch display module with pressure detection and a driving method thereof. [0003] 【Background technique】 [0004] With the advancement of manufacturing technology, the touch display module has successfully integrated the touch panel and the display panel, so that the user can directly instruct the electronic device to perform the desired work through the touch panel. Generally speaking, the touch sensing units and pixel units on the touch display module are arranged in a matrix on a two-dimensional plane, and the timing of updating the display screen and detecting touch points is determined according to the scan pulse signal. [0005] For a general flat display panel, its display screen is composed of two-dimensional pixels, and a TFT-LCD display panel composed of a thin film transistor (TFT) liquid crystal display (LCD) module is taken as an example for illustration. Th...
