Abstract

A method of calibrating a display panel includes making measurements of color components produced by the display panel, receiving an input image signal consisting of one or more pixel represented by input color component values, applying a first non-linear transform to the input color component values of the pixel to produce transformed color component values, wherein the first non-linear transform is either based upon the measurements and the panel design or a ratio of values of color components based upon the measurements, applying a crosstalk correction transform to the transformed color component values to produce crosstalk corrected color component values, applying a second non-linear transform to the crosstalk corrected color component values to produce final color component values, and sending the final color component values to the display panel. A method of calibrating a display panel, includes making measurements of color components displayed on the display panel, using the measurements to generate at least one non-linear crosstalk correction transform, receiving an input image signal consisting of one or more pixel represented by input color component values, changing parameters used in the at least one crosstalk correction transform based upon a current of the panel, and applying one of the at least one crosstalk correction transform having parameters that are a closest fit to the measurements.
