The one or more second transmit levels are less than or equal to the first transmit level. The first pixels cooperating at the first transmit level and the second transmit levels selectively presents the backlight to the second display with a declining intensity pattern in the neighboring pixels.

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.
