Problems solved by technology

[0003] As the market has higher and higher requirements for the thickness and display accuracy of the touch display panel, the number of touch driving electrodes on the array substrate of the touch display panel and the number of touch sensing electrodes on the color filter substrate are increasing. The larger the number, the smaller the area of ​​each touch driving electrode or touch sensing electrode, and the more serious the influence of the parasitic capacitance of the data signal lines, scanning signal lines, liquid crystal capacitors, etc. on the display panel, resulting in touch signal Affected greatly, the touch accuracy drops

Abstract

The invention discloses a touch display panel, a driving method and a touch display device. The touch display panel comprises a shift circuit, a control signal line, a control circuit, multiple scanning lines, multiple data lines, multiple touch driving electrodes, a switching control signal end and a switching control switch unit. During a touch period of a frame cycle, all switching control switches are switched on under the control of a first control signal output by the switching control signal end, so that all the touch driving electrodes are electrically connected with at least one data line through at least one switching control switch; the control circuit enables the scanning lines to be suspended based on the first control signal output by the switching control signal end and a signal at the output end of the shift circuit. Through the touch display panel, coupling between devices on the touch display panel is lowered, stray capacitance between the scanning lines and other devices is eliminated, and the signal detection precision of the touch display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, specifically to the field of organic light-emitting display technology, and in particular to a touch display panel, a driving method, and a touch display device. Background technique [0002] With the continuous improvement of the application field and technology of touch display technology, more touch driving electrodes can be arranged on the array substrate of the touch display panel, and more touch sensing electrodes can be arranged on the color filter substrate to improve the touch Control the accuracy of the display panel to sense the touch signal. [0003] As the market has higher and higher requirements for the thickness and display accuracy of the touch display panel, the number of touch driving electrodes on the array substrate of the touch display panel and the number of touch sensing electrodes on the color filter substrate are increasing. The larger the number, the smaller...
