Abstract: A display device, a driving method thereof, and a display equipment are provided. The display device includes a driving module. The present disclosure allows a display panel to maintain a same brightness for image display when the display panel refreshes images at different refresh rates by allowing the refresh rates to correspond to gamma voltages and adjusting the gamma voltages to adjust a brightness of the display panel when a current refresh rate of the display panel changes. Serious flickers of the display device caused by the display device being switched at different refresh rates in a short time can be prevented.

Abstract: The present application provides a luminance compensation method, a luminance compensation device, and a display device. Luminance compensation is performed on at least part of consecutive frames satisfying a condition of the luminance compensation, and the luminance compensation is not performed on the consecutive frames not satisfying the condition of the luminance compensation, thereby preventing a problem that the luminance compensation applied to a display device with free synchronization technology of traditional technology causing display of special images to deteriorate.
