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.

Temperature sensing circuit and driving circuit

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&#x2212;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.
