  • Display apparatus and control method for power loss thereof
    Patent number: 10802331
    Abstract: A display apparatus is provided. The display apparatus includes a display panel, a backlight module, a power-supply circuit, and a system-control circuit. The display panel is configured to display an image signal. The backlight module is configured to provide backlight to the display panel. The power-supply circuit is configured to convert an alternating current (AC) source to a direct current (DC) voltage. The system-control circuit includes a power-loss-detection circuit and a display controller. The power-loss-detection circuit is configured to detect whether the DC voltage from the power-supply circuit has a power-loss event. The display controller is configured to control the display panel and the backlight module. In response to the power-loss-detection circuit detecting that the DC voltage has the power-loss event, the display controller performs a predetermined shutdown procedure to sequentially turn off the backlight module and the display panel.
