Abstract

The invention discloses a touch display panel which comprises a first substrate, a second substrate, a first touch electrode, a second touch electrode and a detecting unit, wherein the first touch electrode is arranged on the first substrate; the first touch electrode is arranged as an integrated electrode; the second touch electrode is arranged on the second substrate; the second touch electrode comprises a plurality of second touch sub-electrodes; the detecting unit is used for detecting the capacitance change between the second touch sub-electrodes of the first touch electrode and the second touch electrode and confirming the touch position according to the positions of the second touch sub-electrodes corresponding to the generated capacitance change. The touch display panel can realize multi-point touch while ensuring the panel thinning and can be used for detecting the magnitude of the touch pressure. The invention also discloses a driving method for the touch display panel.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, and in particular relates to a touch display panel and a driving method thereof. Background technique [0002] With the rapid development of display technology, touch display panels are increasingly applied to various electronic products, such as smart phones, notebook computers, and tablet computers. [0003] According to different sensing technologies, touch display panels can be divided into four types: resistive, capacitive, optical, and acoustic. Currently, the mainstream touch technology is capacitive. However, the existing capacitive touch display panels cannot be used in combination of normal touch and pressure touch. [0004] For example, although the known self-capacitive touch display panel has a relatively simple structure, it cannot accurately detect the magnitude of the touch pressure. Contents of the invention [0005] In order to solve one or more aspects of the above pro...
