Abstract: A display driver circuit receives externally-encoded image data and processes the data using a memory (graphic RAM), an internal encoder, and an external decoder configured to operate on the externally-encoded image data. The processed data is provided to a display device by a source driver of the display driver circuit. Data is processed through the graphic RAM and an internal decoder or the external decoder depending on whether a slice of the data is a currently received update slice, a recently received standby slice, or a still slice.

Abstract: An electronic device includes a display panel that includes a first region including first pixel groups and a second region including second pixel groups, and a compensation circuit. The compensation circuit may receive first image data. The compensation circuit may compensate to generate second image data in response to a determination that the first image data corresponds to at least one of one or more particular first pixel groups that are adjacent to a boundary between the first region and the second region or one or more particular second pixel groups that are adjacent to the boundary. The compensation circuit outputs the second image data to the display panel.
