摘要:
The present application discloses a method for preventing false output of a GOA circuit in a display panel. The method includes providing N clock signals respectively to N GOA units in each of M groups of GOA units cascaded in series. The N clock signals are outputted time-sequentially from a 1st clock signal to a N-th clock signal. The method additionally includes counting a first total number of pulses of the 1st clock signal and a second total number of pulses of the N-th clock signal, comparing each of them to M, and generating a reset signal based on a determination that at least one of the first total number of pulses and the second total number of pulses is smaller than M. The method furthermore includes releasing residual charges of the GOA circuit without outputting any gate-driving signal for a duration of time.
