Patent ID: 10847075

Abstract:
A display device has an image processing unit that determines an error for a pixel location that is based on the difference between an input color dataset and an output color dataset. The error is fed back to the image processing unit to propagate and spread across other neighboring pixel locations. In generating the output color values, the most significant bits (MSBs) and the least significant bits (LSBs) may be treated separately. The display device may extract the MSBs from the input and generate a first output color sub-dataset that is related to the MSBs. The display device may determine the LSBs from a difference between the input color dataset and the output MSBs. The display device may process the LSBs to compensate, adjust, scale, and quantize the values. The MSBs and LSBs may be re-combined to determine an actual color value displayed at the pixel location to determine the error.
