Abstract:
The disclosure provides a GOA driving circuit comprising a plurality of GOA driving unit stages. When power is turned off, the pull-up control module controls the pull-up output module to stop outputting the clock signal, the pull-down control module controls the pull-down output module to stop outputting the low potential signal, the first global control module outputs the high potential signal, the reset module stops outputting the reset signal, and the second global control module stops outputting the low potential signal. Generation of the residual image on the liquid crystal screen is prevented when power is turned off.
