And the wiring in the effective display area of the display screen is also influenced by static electricity, so that bad display is caused, and the display quality of the mobile phone is influenced. In the process of manufacturing a display panel, static electricity causes many defects, so the design of an electrostatic discharge (ESD) prevention structure on the display panel such as LCD, OLED, and mini/micro is important.

The main purpose of taking thinning as a design idea is as follows: when static electricity occurs, the static electricity signal is conducted to GND/Com and other large-capacity signals through the discharging circuit, thereby protecting the easily damaged circuit. The main purpose of taking the plug as a design idea is as follows: when static electricity occurs, the fuse at the port is fused by instantaneous large current generated by the circuit, so that the static electricity signal is prevented from entering the panel to cause damage.
Although both designs can be used for ESD protection, there are disadvantages. Specifically, the tip discharge type circuit has poor discharge capability and poor ESD protection effect. Although both the floating gate TFT discharge type circuit and the TFT diode discharge type circuit discharge by using the TFT, the circuit design is complex, the TFT has the risk of electric leakage in a normal working state, and meanwhile, a TFT device occupies a certain space, so that the width of a non-display area is increased, and the floating gate TFT discharge type circuit and the TFT diode discharge type circuit are not suitable for the current mainstream narrow frame, ultra-narrow frame or spliced display products. The design of setting the fuse at the port, although the fuse needs a certain time to blow, may also have the risk of not blowing completely, leads to the anti-ESD circuit to explode and hinder the risk higher.
