Abstract:
A power supply configured to receive at least one of a first input voltage and a second input voltage and to generate a voltage of a first pixel power and a voltage of a second pixel power, includes: a voltage sensing unit for generating voltage sensing signals corresponding to the first input voltage and the second input voltage; a first power generating unit for receiving the first input voltage and generating the voltage of the first pixel power corresponding to the voltage sensing signals; a second power generating unit for receiving the second input voltage and generating the voltage of the first pixel power corresponding to the voltage sensing signals; and a third power generating unit for receiving the first input voltage and the second input voltage, utilizing the first input voltage or the second input voltage, and generating the voltage of the second pixel power corresponding to the voltage sensing signals.
