Abstract:
A display device includes a display panel, a power supply, and a driving circuit. The display panel includes a plurality of pixels. The power supply is configured to supply a first power voltage and a second power voltage to the display panel. The driving circuit is configured to determine, based on a viewing angle information signal, whether to operate the display device in a general mode or a low power mode. If the display device is operated in the low power mode, the driving circuit is further configured to deactivate the power supply, and supply a first subsidiary power voltage and a second subsidiary power voltage to the display panel.
