  • Patent number: 10210828
    Abstract: 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.

    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.
