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.
