Abstract
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.
