    摘要: 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.

    摘要: An n-stage driving module with a common control node according to the present invention is revealed. The n-stage driving module comprises a plurality of output units, a forward input unit and a reverse input unit. The output units are all coupled to a control node to share the control node. The output units output forward scanning signals sequentially according to the charge of the control node when the control node is charged by the forward input unit. The output units output reverse scanning signals sequentially according to the charge of the control node when the control node is charged by the reverse input unit. Thus, the present invention is provided to output forward or reverse scanning signals from the output units by sharing the control node so as to decrease the circuit area in the n-stage driving module.
