[0030] Example 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. like figure 1 As shown, the present embodiment provides a touch panel 100, which includes a touch area 110 and a non-touch area. The non-touch area is provided with a signal line 120 and at least two GND lines 130. The GND lines 130 are provided with 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 the art, a more commonly used electrostatic protection method for touch display panels is to set a GND line around the touch area 110 at the peripheral edge of the touch area 110 , and the GND line is connected to the ground terminal of the driving circuit of the touch panel. electrical connection. When the touch panel generates static electricity, the electrostatic charge flows to the ground termin...

[0042] Embodiment 2
[0043] figure 2 It is a schematic structural diagram of another implementation manner of the touch display panel in the embodiment of the present invention. like figure 2 As shown, the present embodiment provides a touch panel 100, which includes a touch area 110 and a non-touch area. The non-touch area is provided with a signal line 120 and at least two GND lines 130. The GND lines 130 are provided with In the peripheral area of the signal line 120 , the GND trace 130 is electrically connected to the ground terminal of the external driving circuit 140 . All GND lines 130 are combined into a GND bus by conductive glue before being electrically connected to the ground terminal of the external driving circuit 140 , 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 lines is large, before the GND lines are electrically connected to the ground terminal...

[0053] Embodiment 3
[0054] image 3 It is a schematic structural diagram of still another implementation manner of the touch display panel in the embodiment of the present invention. like image 3 As shown, the present embodiment provides a touch panel 100, which includes a touch area 110 and a non-touch area. The non-touch area is provided with a signal line 120 and at least two GND lines 130. The GND lines 130 are provided with 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 . The adjacent GND traces 130 are short-circuited through the conductive material 131 .
[0055] In this embodiment, two adjacent GND traces 130 can be short-circuited through the conductive material 131 . Optionally, when designing GND lines, each adjacent GND line may be short-circuited through a metal conductive layer. In this way, fast shunting of static electricity can be achieved.
