Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0052] Existing in-cell touch display devices integrating pressure-sensing technology are usually based on in-cell touch display devices, and a film electrode with pressure-sensing function is attached to the outside. , it is necessary to increase the corresponding external paste process, increase the production cost, and add a layer of structure on the display side of the display device, which will reduce the light transmittance of the embedded touch display d...

Abstract

The invention provides a touch display panel, a driving method thereof and an embedded touch display. The touch display panel comprises an array substrate, a plurality of first electrodes arranged on the array substrate, and second electrodes arranged on the same layer of the first electrodes, wherein the second electrodes are electrically insulated from the first electrodes; the first electrodes are used for detecting touch positions in the first time slot; the first electrodes and the second electrodes are used for detecting touch pressure in the second time slot; and the first time slot and the second time slot are not superposed in a time sequence. When the touch display panel is touched, the first electrodes serve as pressure sensing electrodes, the new second electrodes serve as pressure reference electrodes, and a pressure sensing unit is formed by the first electrodes and the second electrodes; and under the action of different pressures, the first electrodes and the second electrodes have different deformations, and the capacitance changes of touched positions are different, so that pressure is sensed according to the detected capacitance changes.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display panel, a driving method thereof, and an embedded touch display. Background technique [0002] Embedded touch display refers to the structure of embedding the touch panel function into the display panel, that is, embedding the touch sensor function inside the display screen, which can make the screen thinner and lighter. [0003] In recent years, with the development of embedded touch display technology, people's expectations for touch panels are not limited to the detection of the touch position, but also hope that the pressing force can be detected when touching, that is, the pressure touch function can be realized. . The pressure touch technology integrates a pressure-sensing function on the touch panel. Lightly touching the screen with a finger and pressing hard will bring different interactive effects. That is to say, the screen can sense diffe...
