Title:
GOA SIGNAL DETERMINING CIRCUIT AND DETERMINING METHOD, GATE DRIVING CIRCUIT, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/219763
Kind Code:
A1
Abstract:
A GOA signal determining circuit and determining method, by which the GOA output anomaly caused when part of output signals of a GOA are lost in a frame can be avoided. The GOA signal determining circuit is connected to an input end (input) of a GOA unit, at least two clock signal ends (CLK1, CLK2, CLK3 and CLK4) of the GOA unit and a control end (Tot-RST) of a reset unit of a PU node in the GOA unit. The GOA signal determining circuit is used for detecting signals of the input end (input) of the GOA unit and the at least two clock signal ends (CLK1, CLK2, CLK3 and CLK4) of the GOA unit; when it is determined that the signals of the input end (input) of the GOA unit and the at least two clock signal ends (CLK1, CLK2, CLK3 and CLK4) of the GOA unit are all abnormal, a control signal is sent to the reset unit of the PU node, so as to control the reset unit to output a reset signal to the PU node and turn off an output transistor (Tup) of the GOA unit, signals inputted by at least one pair of clock signal ends in the at least two clock signal ends (CLK1, CLK2, CLK3 and CLK4) being supplementary with each other.
