Abstract: A display driver includes image processing circuitry and drive circuitry. The image processing circuitry is configured to receive a foveal image, a full frame image, and coordinate data that specifies a position of the foveal image in the full frame image. The image processing circuitry is further configured to render a resulting image based on the full frame image independently of the foveal image in response to detection of a data error within the coordinate data. The drive circuitry is configured to drive a display panel based on the resulting 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.

Abstract: A display driver includes image processing circuitry, driver circuitry, and test circuitry. The image processing circuitry is configured to generate first output data during a first display update period and generate second output data during a second display update period. The driver circuitry is configured to update a display panel based on the first output data during the first display update period and update the display panel based on the second output data during the second display update period. The test circuitry is configured to test the image processing circuitry during a test period disposed between the first display update period and the second display update period.

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.
