[0045] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.
[0046] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs.

Figure 1 As shown, Figure 1 is a schematic plan view of a peripheral area of a display panel in the related art; Figure 2 It is a partial cross-sectional schematic diagram of the peripheral area of the display panel in the related art; the touch layer 300 in the display panel is located above the cathode layer 200, and the cathode signal of the cathode layer 200 is provided by the low-level voltage signal (ELVSS signal) 110 of the array substrate (LTPS) 100, that is, the cathode signal of the cathode layer 200 is below the touch signal in the display area; in the non-display area, the touch signal line is concentrated and runs directly above the low-level voltage signal routing (ELVSS) 110 / high-level voltage signal routing (ELVDD) 120 of the array substrate (LTPS) 100. Considering reliability, large pieces of metal usually need to be opened for water vapor release.
