The temperature sensing circuit 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. |
