Abstract
A display system includes a display panel, a display driving circuit and a power management circuit. Display panel includes a plurality of pixel circuits. Display driving circuit is coupled to the display panel and configured to periodical signals and a data signal to the display panel. Data signal is configured to assign a gray level to each of the pixel circuits. Power management circuit is coupled to the display driving circuit and the display panel and is configured to provide a first operating voltage and a second operating voltage to the pixel circuits. The first operating voltage is higher than the second operating voltage. Display driving circuit is configured to provide a first horizontal synchronizing signal to the power management circuit. Power management circuit is configured to adjust at least one of the first operating voltage and the second operating voltage in response to the first horizontal synchronizing signal.
