Touch display panel, preparation method thereof and display device

Abstract

An embodiment of the invention discloses a touch display panel, a preparation method thereof and a display device. The touch display panel of the embodiment comprises a grounding wire and an electronic switch, wherein the grounding wire is used for releasing static electricity; and the electronic switch is arranged on the grounding wire and is switched on or switched off according to the working state of the touch display panel. By optimization of routing and a working mode of the grounding wire of the display panel, switch-on and switch-off of the grounding wire are separately controlled whendisplay and touch functions are carried out on the display panel, and the displaying property and the touch property of the overall display panel are uniform.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel, a manufacturing method thereof, and a display device. Background technique [0002] Multi-touch function As the display and touch integration of small-sized display panels is getting higher and higher, and due to the increasingly stringent requirements of users for display and touch performance, currently various display panels are willing to use touch The control function is integrated inside the panel, that is, the off-screen touch effect of the display panel is realized. However, with the increase of integration level, many display panels also have many problems, such as the decrease of sensitivity and accuracy of touch performance. attribute to judge whether the touch function is complete and whether there is any abnormality. Since the capacitive properties of current display panel products are not stable enough, there is a phenomenon of unev...

AI Technical Summary

Problems solved by technology

However, with the increase of integration level, many display panels also have many problems, such as the decrease of sensitivity and accuracy of touch performance, because the existing display panel realizes the touch function under the screen through the capacitance of the panel itself. attribute to judge whether the touch function is complete and whether there is any abnormality

Since the capacitive properties of current display panel products are not stable enough, there is a phenomenon of uneven distribution of capacitance values ​​across the entire panel, which makes the uniformity of the touch effect across the panel poor.
