ENCODING DEMURA CALIBRATION INFORMATION

Abstract:

A system and method for encoding, transmitting and updating a display based on demura calibration information for a display device comprises generating demura correction coefficients based on display color information, separating coherent components from the demura correction coefficients to generate residual information, and encode the residual information using a first encoding technique. Further, the image data may be divided into data streams, compressed and transmitted to from a host device to a display driver of a display device. The display driver decompresses and drives subpixels of the pixels in based on the decompressed data. The display driver updates the subpixels of a display using corrected greyscale values for each subpixel are determined from the decompressed data.
