Title: PROTECTIVE CIRCUIT FOR GATE DRIVER ON ARRAY UNIT, AND ARRAY SUBSTRATE
Abstract:
A protective circuit for a gate driver on array unit, which relates to ESD or EOS protection for the gate driver on array (GOA) unit. The protective circuit comprises: a first voltage gating module (21), which is configured to output, when a gate line signal output end (VG) should output a valid driving voltage of a gate driving signal, an output voltage (VDD1) of an output end of the first voltage source; and a first protective module (22), an input end of which is connected to an output end of the first voltage gating module (21) and an output end of which is connected to a gate line, wherein in the case where the output voltage (VDD1) of the first voltage source and a current output voltage of the gate line signal output end (VG) satisfy a first predetermined condition, the first protective module (22) outputs the output voltage (VDD1) of the output end of the first voltage source as an adjusted gate driving signal (VGG).
