A method for adjusting the display of a terminal provided with an under-screen image capturing device includes adjusting the brightness of the display above the under-screen image capturing device. First display brightness within a first display region is detected and second display brightness within a second display region is detected when a display screen of a terminal is displaying an image. Grayscale brightness within the first display region is adjusted based on the first display brightness and the second display brightness to allow adjusted grayscale brightness within the first display region to be consistent with grayscale brightness within the second display region.

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.
