Abstract
A global dimming display device and its control circuit and an operation method are provided. The global dimming display device includes a display panel module, a backlight panel module, and a control circuit. The backlight panel module provides backlight to the display panel module. The control circuit checks an image frame. In response to the image frame not being a dark picture, the control circuit performs global dimming on the backlight panel module to set backlight brightness of backlight to normal backlight brightness. In response to the image frame being a dark picture, the control circuit performs global dimming on the backlight panel module to dim the backlight brightness from the normal backlight brightness to dark picture backlight brightness, and gains the image frame of the display panel module to enhance a pixel gray level of the image frame.
