ABSTRACT:
A display driving circuit includes a temperature compensation adjustment circuit, a control circuit, a full bridge circuit, and a transformation circuit. The temperature compensation adjustment circuit provides a current signal for the control circuit. The value of the current signal changes along with environment temperature changes. The control circuit controls the full bridge circuit based on the current signal. An output voltage signal of the full bridge circuit decreases as the current signal increases, and when the environment temperature decreases. The transformation circuit amplifies the output voltage signal of the full bridge circuit to drive a display.
