Abstract: A display driver includes interface circuitry, image processing circuitry, and drive circuitry. The interface circuitry is configured to receive a full frame image and a foveal image from a source external to the display driver. The image processing circuitry is configured to: upscale the full frame image; render a foveated image from the upscaled full frame image and the foveal image. The foveated image includes a foveal area based on the foveal image, a peripheral are based on the upscaled full frame image, and a border area based on the foveal image and the upscaled full frame image. The border area being located between the foveal area and the peripheral area. The drive circuitry is configured to drive a display panel using the foveated image.

Abstract: A display driver includes: a receiver configured to receive image data of each line of a display panel from an external device; a line latch circuit having a line latch configured to latch the image data of each line received by the receiver in response to a strobe signal; a driving circuit section which drives the display panel in response to the image data latched by the line latch; and a timing controller configured to generate the strobe signal. The receiver is configured to detect occurrence of transmission error in data transmission about each line. The timing controller is configured to generate the strobe signal in response to a detection result of the occurrence of transmission error.
