Abstract
A pixel driving circuit includes a first driver and a second driver. The first gate driver includes a plurality of stage units connected to odd-numbered gate lines. The second gate driver includes a plurality of stage units connected to even-numbered gate lines. Each of the stage units of the first and second gate drivers includes an input unit, a first signal output unit, and a second signal output unit. The input unit outputs a driving control signal according to a previous stage driving signal output from the previous stage unit and a next stage driving signal output from the next stage unit. The first signal output unit outputs a stage driving signal according to the driving control signal and a driving clock signal. The second signal output unit outputs a gate voltage signal to the corresponding gate line according to the driving control signal and a gate clock signal.
