Error correction for display device

A display device, comprising:

• a first set of light emitters configured to emit light for a first pixel location;
• a second set of light emitters configured to emit light for a second pixel location;
• and
• an image processing unit configured to:
• receive a first input color dataset representing a color value intended to be displayed at the first pixel location;
• generate, from the first input color dataset, a first output color dataset for driving the first set of light emitters;
• determine an error correction dataset representing a compensation of color error of the first set of light emitters resulting from a difference between the first input color dataset and the first output color dataset;
• receive a second input color dataset for the second pixel location;
• dither, using values in the error correction dataset, the second input color dataset to generate a dithered second color dataset;
• and
• generate, from the dithered second color dataset, a second output color dataset for driving the second set of light emitters.

An image processing unit of a display device, comprising:

• an input terminal configured to receive input color datasets for different pixel locations, each input color dataset representing a color value intended to be displayed at a corresponding pixel location;
• an output terminal configured to transmit output color datasets to a display panel of the display device, each output color dataset configured to drive a set of light emitters;
• a data processing unit configured to:
• for each pixel location,
• determine, a difference between the input color dataset and the output color dataset corresponding to the pixel location;
• determine an error correction dataset based on the difference;
• and
• adjust input color datasets corresponding to neighboring pixel locations of the pixel location based on the error correction dataset.
