Abstract
The present invention relates to a display driving circuit, which comprises a power circuit a panel driving circuit. The power circuit receives an input voltage, which is the electrical potential difference between a first input electrical potential and a second input electrical potential, and produces a first supply electrical potential and a second supply electrical potential according to the first input electrical potential and the second input electrical potential for providing a supply voltage. The supply voltage is the electrical potential difference between the first supply electrical potential and the second supply electrical potential. The first supply electrical potential is higher than the second supply electrical potential. The second supply electrical potential is between the first input electrical potential and the second input electrical potential. The panel driving circuit is coupled to the first supply electrical potential and the second supply electrical potential for receiving the supply voltage and generating a plurality of driving signals.
