The error is fed back to the image processing unit to propagate and spread across other neighboring pixel locations. In generating the output color dataset, an error-modified dataset that includes the input dataset and the error may first be generated. The error-modified dataset is examined to ensure the color values fall within the display gamut. The color dataset is also quantized and dithered to make the output dataset having a bit depth that is compatible with what the light emitters can support. Lookup tables and transformation matrices may also be used to account for any potential color shifts of the light emitters due to different driving conditions such as driving currents."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Error correction for display device","description":"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.
