Title: ELECTROSTATIC PROTECTION CIRCUIT, ARRAY SUBSTRATE, DISPLAY PANEL AND DISPLAY APPARATUS
Abstract:
Provided are an electrostatic protection circuit, an array substrate, a display panel and a display apparatus. The electrostatic protection circuit is located in a peripheral region (a) of an array substrate, and comprises: a first ground wire (1) arranged on the same layer as a source electrode and a drain electrode of a thin film transistor located in a display region (b) of the array substrate, and a second ground wire (2) arranged on the same layer as a gate electrode of the thin film transistor, wherein the first ground wire (1), and a printed circuit board (3) arranged in the peripheral region (a) form a first loop, the first loop surrounds the display region (b); and the second ground wire (2) and the printed circuit board (3) form a second loop, and the second loop surrounds the display region (b). Since the two ground wires are respectively arranged on the same layer as the source and drain electrodes and the gate electrode of the thin film transistor located in the display region of the array substrate, no process for manufacturing the array substrate is added.
