摘要:
A display device is provided that includes a plurality of pixel circuits that are arranged in a matrix and supplied with power through a first power supply line maintained at a first voltage and a second power supply line maintained at a second voltage having a positive value less than the first voltage. The display device also includes a first power supply circuit of a synchronous rectification type that outputs the first voltage to the first power supply line by chopping an input voltage. The display device further includes a second power supply circuit of the synchronous rectification type that outputs the second voltage to the second power supply line by chopping the first voltage.
