Abstract
A GOA driving panel is disclosed. The GOA driving panel includes a plurality of GOA driving units and a plurality of output capacitors. Each output capacitor is arranged between a GOA driving unit and a corresponding scanning line so that an output waveform of a row scanning signal output by the GOA driving unit is a delay waveform. In the GOA driving unit, a difference among feedback voltages of pixel units in different active areas of the panel can be effectively reduced, whereby image flicker of the panel can be alleviated, and display quality thereof can be improved.
