ABSTRACT:
A power driver circuit for a display panel. The power driver circuit includes a power controller, and a resident power system, which is coupled to an alternating power source and provides resident power for the power controller. When receiving an external on/off signal, the power controller will output driving signals to initiate or close the low-voltage power converter system and the high-voltage power converter system to determine whether a low-voltage power and a high-voltage power are output to drive the display panel. Thereby, when the display panel is in an off state, only the resident power system works. Thus, the power-saving demand of environmental protection is satisfied.
