[0019] Please also see figure 1 and figure 2 , which respectively show a schematic cross-sectional structure diagram of the touch display panel and a structural schematic diagram of the pressure-sensitive detection layer of the touch display panel according to the first embodiment of the present invention. Such as figure 1 As shown, in an optional embodiment of the present invention, the touch display panel may be a touch liquid crystal display panel or a touch OLED display panel. The touch display panel includes a first substrate 1 , a plurality of gate signal lines 2 and a pressure sensing layer 3 .
[0020] exist figure 1 In the illustrated embodiment, the first substrate 1 is optionally an array substrate. A plurality of gate signal lines 2 are disposed on the first substrate 1 . Such as figure 1 As shown, a plurality of gate signal lines 2 are arranged parallel to each other on the first substrate 1 . In the embodiment of the present invention, the gate signal lin...

[0039] The third embodiment of the present invention is another implementation of the touch display panel of the present invention, please refer to Figure 5 , which shows a schematic structural diagram of the pressure-sensitive detection layer of the touch display panel according to the third embodiment of the present invention. with the above figure 2 The difference of the first embodiment shown is that in this embodiment, the pressure-sensitive detection layer 3 includes a first electrode 31" corresponding to the size of the area where the plurality of gate signal lines 2 are located. Specifically, as Figure 5 As shown, the pressure-sensitive detection layer 3 is only formed by a large-sized first electrode 31" corresponding to the area where the plurality of gate signal lines 2 are located (ie, the display area of the touch display panel). This embodiment can realize the above-mentioned figure 1 and figure 2 The first embodiment shown has a similar effect, and since...
