Abstract
Embodiments of the present disclosure relate to a display assembly with color calibration for improving accuracy of displayed colors under thermal shifts. A data processing circuit of the display assembly determines color compensation coefficients corresponding to an operating temperature of a display panel, each color compensation coefficient accounting for a thermal shift of a respective color component at the operating temperature. The data processing circuit applies the color compensation coefficients to color transform elements corresponding to an initial temperature to determine a corrected version of the color transform elements corresponding to the operating temperature. The data processing circuit processes pixel values of color components in a first format associated with the display panel at the operating temperature by applying the corrected version of the color transform elements to generate corrected pixel values of the color components in a second format for presentation on the display panel at the operating temperature.
