The invention provides a display equipment, an operation method thereof, and a backlight control device. The display equipment includes a display panel, a backlight module, an image processing circuit, a panel control circuit, a first backlight control circuit, and a second backlight control circuit. The image processing circuit provides a VRR video frame to the panel control circuit. The first backlight control circuit generates a main dimming signal to the backlight module during a valid data period of the VRR video frame according to a first timing information of the image processing circuit. The second backlight control circuit generates a compensation dimming signal to the backlight module during a blank period of the VRR video frame according to a second timing information of the image processing circuit. In particular, a peak current value of the compensation dimming signal is less than a peak current value of the main dimming signal.

Display equipment and operation method thereof and backlight control device that solves flicker phenomenon of variable refresh rate video frame

A liquid crystal display panel is provided. The liquid crystal display panel includes a liquid crystal display panel, a backlight module and a control circuit. The control circuit is coupled to the liquid crystal display panel and the backlight module. The control circuit is configured to control the liquid crystal display panel to display a corresponding image according to image data, and control the backlight module to provide backlight to the liquid crystal display panel. The control circuit determines a turn-on time point of each of a plurality of zones of the backlight module according to a response time of the liquid crystal display panel and a writing period of at least one target display area of the liquid crystal display panel. The control circuit further determines the turn-on time length of each zone according to the image data corresponding to the grayscale data of each zone.

Liquid crystal display panel and image display method

An electronic device and a power adjustment method thereof are provided. The electronic device includes at least one data connection port, a charge controller, at least one charging connection port, and a power controller. The charge controller controls charging power of the at least one charging connection port. The power controller is directly or indirectly electrically coupled to the at least one data connection port and the charge controller. The power controller assigns a first idle power corresponding to the at least one data connection port not connected to an external data load to the charging controller for use in response to determining that the at least one charging connection port is connected to an external to-be-charged load and one of the at least one data connection port is not connected to the external data load.
