Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0031] figure 1 It is a driving schematic diagram for realizing different display refresh rates in the prior art, such as figure 1 As shown, as users’ demands for display and touch become more and more diverse, for display products with integrated touch functions, in order to meet the needs of different application scenarios, different display refresh rates are often switched, but it is necessary to maintain Higher touch refresh rate and constant frequency. At present, in the display terminal, it is generally ad...

Abstract

The invention discloses a touch display panel, a driving method of the touch display panel and a touch display device. The touch display panel comprises a display area and a non-display area. The display area comprises a plurality of sub-pixels and a plurality of touch electrodes; the non-display area comprises a driving chip and a display multi-path selection circuit; the working stage of the touch display panel comprises a plurality of working refreshing stages, and the working refreshing stages comprise a first refreshing stage and a display intermittent stage; the first refreshing stage comprises a display refreshing sub-stage and a first touch refreshing sub-stage; the driving chip is used for transmitting display signals to the sub-pixels in the display refreshing sub-stage, transmitting a touch signal to the touch electrode in the first touch refreshing sub-stage, and transmitting an enabling clock signal to the display multi-path selection circuit in the display intermittent stage, and controlling the display multi-path selection circuit to be switched on. The display multi-path selection circuit is controlled to be switched on to release electrostatic charges in the display intermittent stage, the touch load difference in the first refreshing stage and the display intermittent stage is reduced, and the touch detection effect is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of touch technology, and in particular, to a touch display panel, a driving method thereof, and a touch display device. Background technique [0002] With the popularization and application of electronic devices (such as mobile phones, tablet computers, etc.), electronic devices can support more and more applications, and their functions are becoming more and more powerful. Indispensable electronic supplies. [0003] Touch technology has also become a standard technology for electronic equipment. The touch technology in the prior art has a technical problem that the load corresponding to the touch frame is different under different display frequencies, which affects the touch effect. Contents of the invention [0004] The present invention provides a touch display panel, a driving method thereof, and a touch display device, which solve the technical problem in the prior art that the touch eff...
