The invention provides a display panel with an electrostatic protection function. The display panel comprises a substrate, a first metal wire, a second metal wire, an insulating layer and at least one first electrostatic protection assembly and at least one second electrostatic protection assembly, wherein the first metal wire, the second metal wire and the insulating layer are arranged on the substrate; the insulating layer is arranged between the first metal wire and the second metal wire to electrically isolate the first metal wire and the second metal wire; at least one first electrostatic protection assembly is electrically connected with at least one of the first metal wire and the second metal wire; and the second electrostatic protection assembly is arranged in the region where the first electrostatic protection assembly is located, so that the static generated on at least one of the first metal wire and the second metal wire is guided to the regions where the first and the second electrostatic protection assemblies are located to detonate. According to the display panel, due to the first and the second electrostatic protection assemblies, the static generated by the display panel can be guided to the regions where the first and the second electrostatic protection assemblies are located to detonate, thereby reducing damage to the display panel from the static, and further protecting the display panel.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display panel with an electrostatic protection function. Background technique [0002] In the planar display technology, low temperature polysilicon LTPS (Low Temperature Poly-Silicon, "LTPS" for short) has a characteristic of ultra-high carrier mobility, and has a good market prospect. [0003] Since the LTPS process is more complicated and there are many steps in the process flow, the probability of electrostatic ESD (Electro-Static discharge, "ESD") is relatively high, and the area where ESD is prone to occur is usually the overlapping area between different layers of lines or the same layer Areas with small line spacing. When ESD occurs on the display panel, the lines close to the ESD melt the insulating layer due to the instantaneous strong current, and after the insulating layer cools down, the lines that should not be connected are connected together, thereby aggravati...
