Abstract
A display compensating method, display compensating device, and display device are provided, which relates to field of display and addresses the issues of poor screen uniformity, grayscale relationship change of sub-pixel due to ambient temperature change, and display screen brightness affected by ageing offset of threshold voltage corresponding to the sub-pixel. The display compensating method is applied to the display device, including: converting a received grayscale signal into a brightness signal; performing an optical compensation on a display brightness of the display device based on the brightness signal; converting a corresponding brightness signal on which the optical compensation is performed into a voltage signal; compensating for a threshold voltage corresponding to each sub-pixel in the display device based on the voltage signal; and compensating for operating parameters of the display device for the display device at different operating temperatures.
