Title:

ELECTROSTATIC PROTECTION CIRCUIT, ARRAY SUBSTRATE, AND DISPLAY DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/080577

Kind Code:

A1

Abstract:

Provided are an electrostatic protection circuit, an array substrate, and a display device. The electrostatic protection circuit comprises at least one first transistor (M1) and at least one second transistor (M2). A gate (11) and a first electrode (12) of the first transistor (M1) are connected to a first signal line (P1), and a second electrode (13) of the first transistor (M1) is connected to a second signal line (P2). A gate (21) and a first electrode (22) of the second transistor (M2) are connected to the second signal line (P2), and a second electrode (23) of the second transistor (M2) is connected to the first signal line (P1). Because the first transistor (M1) can discharge static electricity generated by the first signal line (P1) to the second signal line (P2) and the second transistor (M2) can discharge static electricity generated by the second signal line (P2) to the first signal line (P1), short circuit caused by static electricity and other defects can be avoided, and the electrostatic protection circuit does not need to require additional wiring on the array substrate, and accordingly, occupies a small space.
