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： The present invention provides a temperature sensing circuit, which comprises a switching circuit, a charging circuit, and a judging circuit. The switching circuit receives a supply voltage for generating a switching signal. The charging circuit is coupled to the switching circuit and receives the supply voltage. The switching signal controls the charging circuit for generating a voltage signal according to the supply voltage. The judging circuit is coupled to the charging circuit for generating a judging signal according to the level of the voltage signal. The levels of the switching signal and the voltage signal are related to a temperature state; and the judging signal represents the temperature state. The temperature sensing circuit can be applied to the driving circuit of a display panel for detecting the temperature state. Hence, the level of the driving signal of the driving circuit can be adjusted for improving the image quality.

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.
摘要翻译： 揭示了具有根据本发明的公共控制节点的n级驱动模块。 n级驱动模块包括多个输出单元，正向输入单元和反向输入单元。 输出单元都耦合到控制节点以共享控制节点。 当控制节点由正向输入单元充电时，输出单元根据控制节点的电荷依次输出正向扫描信号。 当控制节点由反向输入单元充电时，输出单元根据控制节点的电荷依次输出反向扫描信号。 因此，本发明被提供用于通过共享控制节点来输出来自输出单元的正向或反向扫描信号，以便减少n级驱动模块中的电路面积。
