Embodiment 1

[0032] An embodiment of the present invention provides a touch display panel (hereinafter referred to as a touch display panel), referring to figure 1 , 2 As shown, the touch display panel is provided with driving electrodes 1 and sensing electrodes 2, and is also provided with: a patterned anti-static layer 3, which is correspondingly distributed in the area outside the sensing area 4 on the touch display panel, and the sensing area 4 includes: the overlapping area of ​​the driving electrode 1 and the sensing electrode 2; a controllable switch (not shown in the figure), and the antistatic layer 3 is grounded through the controllable switch.

[0033] In the prior art, the antistatic layer is a transparent conductive film covering the entire touch display panel, and the antistatic layer is grounded, but the antistatic layer in this embodiment is only distributed outside the sensing area, and the sensing area referred to here refers to the touch display. The area where the touc...

Abstract

Embodiments of the present invention disclose a touch display panel and a touch display device, which relate to the field of display and can realize the function of protecting against electrostatic damage without affecting the touch function. The touch display panel of the present invention is provided with driving electrodes and sensing electrodes, and is also provided with an anti-static layer corresponding to the area outside the sensing area on the touch display panel, where the sensing area includes: the driving electrode and the overlapping area of ​​the induction electrode; a controllable switch, and the anti-static layer is grounded through the controllable switch.

Description

technical field [0001] The invention relates to the display field, in particular to a touch display panel and a touch display device. Background technique [0002] The touch display screen is developing rapidly. The current mainstream products adopt the structural design of the external touch screen (Add on), but the traditional Add on touch screen has a thick overall structure and high cost. (In Cell) LCD screen has become an important development direction in the field of touch display. [0003] In-Cell refers to the method of embedding the touch panel function into the liquid crystal pixel, that is, embedding the touch sensor function in the liquid crystal box, which can make the screen thinner and lighter. Existing In Cell touch screens generally use capacitive sensing, specifically: touch drive electrodes (Tx electrodes) and sensing electrodes (Rx electrodes) manufactured to realize the touch function are set in the liquid crystal cell, and the Tx electrodes and Rx ele...
