Description

technical field

[0001] The present application relates to the field of display technology, in particular to a substrate and a display panel. Background technique

[0002] Electro Static Discharge (ESD) is a common phenomenon, and the electrostatic problem directly affects the production yield of the display device. Usually, a static protection circuit is arranged around the display substrate to release or equalize high-voltage static electricity, so that the display device is protected from static electricity damage during production, transportation and operation.

[0003] Among them, the electrostatic protection circuit usually uses a thin film transistor as the main device for electrostatic protection. Currently, existing discharge device designs include diode-connected transistors (Diode TFTs) and floating transistors (Floating TFTs). However, in order to meet the requirement of electrostatic protection, the size of the thin film transistor will be designed relatively l...
