Embodiment 1

[0031] figure 1 It is a schematic structural diagram of an implementation manner of a touch display panel in an embodiment of the present invention. Such as figure 1 As shown, this embodiment provides a touch panel 100, which includes a touch area 110 and a non-touch area. A signal line 120 and at least two GND lines 130 are arranged in the non-touch area. The GND lines 130 are set In the peripheral area of ​​the signal line 120 , the GND line 130 is electrically connected to the ground terminal of the external driving circuit 140 .

[0032] In this field, a more commonly used electrostatic protection method for touch display panels is: setting a GND line around the touch area 110 on the peripheral edge of the touch area 110, and the GND line is connected to the ground terminal of the drive circuit of the touch panel. electrical connection. When static electricity is generated on the touch panel, the static charge flows to the ground terminal of the drive circuit through th...

Embodiment 2

[0043] figure 2 It is a structural schematic diagram of another implementation manner of the touch display panel in the embodiment of the present invention. Such as figure 2 As shown, this embodiment provides a touch panel 100, which includes a touch area 110 and a non-touch area. A signal line 120 and at least two GND lines 130 are arranged in the non-touch area. The GND lines 130 are set In the peripheral area of ​​the signal line 120 , the GND line 130 is electrically connected to the ground terminal of the external driving circuit 140 . Before all the GND wires 130 are electrically connected to the ground terminal of the external driving circuit 140 , they are combined into a GND bus through conductive glue, and the GND bus is electrically connected to the ground terminal of the external driving circuit 140 .

[0044] In this embodiment, when the number of GND traces is large, before the GND traces are electrically connected to the ground terminal of the external drive c...

Embodiment 3

[0054] image 3 It is a structural schematic diagram of another implementation manner of the touch display panel in the embodiment of the present invention. Such as image 3 As shown, this embodiment provides a touch panel 100, which includes a touch area 110 and a non-touch area. A signal line 120 and at least two GND lines 130 are arranged in the non-touch area. The GND lines 130 are set In the peripheral area of ​​the signal line 120 , the GND line 130 is electrically connected to the ground terminal of the external driving circuit 140 . Adjacent GND wires 130 are short-circuited through conductive material 131 .

[0055] In this embodiment, two adjacent GND traces 130 can be short-circuited through the conductive material 131 . Optionally, when designing the GND wiring, each adjacent GND wiring can be short-circuited through the metal conductive layer. This method can realize the rapid shunting of static electricity.

[0056] It should be noted that this embodiment do...

Abstract

The invention provides a touch display panel and a touch display device. The touch display panel comprises a touch panel and a display panel, the touch panel comprises a touch area and a non-touch area. A plurality of parallel touch electrodes are arranged in the touch area, a signal line connected with the touch electrodes and at least two GND routing lines are arranged in the non-touch area, theGND routing lines are arranged in the peripheral area of the signal line, and the GND routing lines are electrically connected with the grounding end of an external driving circuit. According to thetouch panel, the electrostatic discharge problem of the touch panel can be solved, and the influence of static electricity on the internal signal lines and the touch electrodes connected with the signal lines is reduced.

Description

technical field [0001] The invention relates to a touch display panel and a touch display device, belonging to the technical field of organic light emitting displays. Background technique [0002] With the development of touch technologies, more and more terminals are equipped with display panels with touch functions. In the touch display panel, electrostatic discharge will affect the normal operation of electronic devices, thus causing abnormal touch operation of the touch display panel. [0003] In an existing touch display panel, a GND line is provided in a non-touch routing area around the touch area of ​​the touch screen, and the GND line is adjacent to the signal line for discharging static electricity. [0004] However, when static electricity is generated outside the touch display panel, the static electricity is quickly released through the outer GND line, which easily breaks down the signal line, resulting in abnormal touch operation of the touch display panel. ...
