Abstract

The invention discloses a substrate and a display panel. The substrate comprises a substrate, a signal line, an electrostatic protection device and a common electrode line. The electrostatic protection device comprises a plurality of first semiconductors and second semiconductors, the first semiconductors and the second semiconductors are alternately arranged, the adjacent first semiconductors and the second semiconductors are in contact connection, and the types of the first semiconductors and the types of the second semiconductors are different. In the alternate arrangement and extension direction of the first semiconductors and the second semiconductors, the electrostatic protection device is provided with a head end and a tail end, the signal line is connected with the head end, and the common electrode line is connected with the tail end. The electrostatic protection device provided by the invention is very small in size, and is favorable for realizing a narrow frame of the display panel.

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...
