Abstract
The invention provides a bidirectional scanning driving circuit, which comprises N stages of driving modules. Driving module comprises an output unit, a forward input unit, and a reverse input unit. For the n-th stage driving module, the forward input unit receives a first input voltage and a front forward scan signal of any of the driving modules lower than or equal to (n−2)th stage for charging or discharging a control node of the output unit. The reverse input unit receives a second input voltage and a back reverse scan signal of any of the driving modules higher than or equal to (n+2)th stage for charging or discharging the control node of the output unit. When the forward input unit is charging the output unit, the output unit outputs a forward scan signal; when the reverse input unit is charging the output unit, the output unit outputs a reverse scan signal.
