Abstract

The invention discloses a driving method for a touch display panel and a touch display device comprising the same.The touch display panel comprises at least one first conductive electrode, at least one second conductive electrode and at least one switch selector.The switch selectors are in coupling connection with the corresponding first conductive electrodes respectively.The switch selectors are used for selectively outputting touch induction signals or pressure induction signals received from the first conductive electrodes.According to the touch display panel, on the basis of not changing an existing touch display panel electrode structure, touch induction electrodes can be reused just by adding the switch selectors, and the touch display panel with a pressure induction function is obtained.

Description

technical field [0001] The present invention relates to the field of touch display technology, in particular, to a touch display panel and a driving method of a touch display device including the same. Background technique [0002] The application of touch display devices (such as smart phones, tablet computers, etc.) is becoming more and more popular. In addition to the traditional two-dimensional touch technology, there is also a Force Touch technology that can sense pressure. The pressure touch technology realizes a better human-computer interaction experience for users by sensing pressure information on a touch display device. [0003] At present, components such as sensing electrodes are usually added to the middle frame of the touch display device or the backlight module of the liquid crystal display, and the pressure is realized by detecting the change in capacitance caused by the gap between the display module and the middle frame. induction. Such a design requires...
