POWER MANAGEMENT DRIVER AND DISPLAY DEVICE HAVING THE SAME

摘要

A power management driver includes a boost converter, a plurality of regulators, a sequence controller, and an operation controller. The boost converter converts an input voltage to a source drive voltage for drive a source driver based on a drive enable signal. The regulators regulate the source drive voltage to generate a plurality of drive voltages. The regulators corresponding to a respective number of predetermined devices. The sequence controller controls the timing for providing the source drive voltage to the source driver. The operation controller adjusts active periods of first and second control signals to control the regulators and the sequence controller.
