Claim 16:
17. An overcurrent protection method, applied to the display apparatus according to claim 16, the overcurrent protection method comprising:
outputting, by the system board of the display apparatus, the power supply signal and the display signal to the driver circuit of the display apparatus;
receiving, by the power supply circuit in the driver circuit, the power supply signal;
supplying, by the power supply circuit in the driver circuit, power to the timing controller and the overcurrent protection circuit in the driver circuit;
receiving, by the timing controller, the display signal;
generating, by the timing controller, the plurality of gate input signals for input to the gate driver circuit of the display apparatus according to the display signal;
acquiring, by the overcurrent protection circuit, the plurality of gate input signals;
continuously detecting, by the overcurrent protection circuit, the plurality of gate input signals;
if overcurrent of a gate input signal is detected, outputting, by the overcurrent protection circuit, the second control signal to the power supply circuit;
receiving, by the power supply circuit, the second control signal; and
under control of the second control signal, the power supply circuit stopping receiving the power supply signal output by the system board.
