Abstract
In one embodiment, a computing system may access an image to be displayed on a display. The system may perform compensation operations on the display to compensate for degradation effects of the display. The system may determine a change in an electric signal level associated with one or more light-emitting elements of the display. The change may be caused by the compensation operations. The system may determine a wavelength shift of the light-emitting elements of the display. The wavelength shift may be caused by the change of the electric signal level. The system may adjust values of RGB color components of the pixel values of the image based on the wavelength shift of the light-emitting elements of the display. The system may output the pixel values with the adjusted values of the RGB color components to the display.
