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.

An electronic device is provided. The electronic device includes a display including a plurality of display pixels, a memory, and at least one processor, wherein the at least one processor may be configured to drive the display by variably adjusting a first display region and a second display region in which visual information is to be displayed on the display, based on an operation state or a display structure state of the electronic device, calculate a difference in usage of the display between the first display region and the second display region, variably determine a size of a boundary compensation region between the first display region and the second display region, based on the difference in usage, and compensate for an image of the boundary compensation region.

An electronic apparatus using a liquid crystal display device, a display control method used in the liquid crystal display device, and a non-transitory recording medium for storing a display control program, sets a region having a larger area of an information display region and a background region as a transmission region and a region having a smaller area as a shielding region. A tint change of the shielding region caused by a TN type liquid crystal and a light source for backlight is reduced, and thus, it is possible to make the tint change depending on the viewing direction unremarkable.

An electronic-drum module for connection to one or more electronic-drum pads is provided. The module includes an electronic display; a first memory storing audio files for playback when the playback is triggered by a signal received from a pad; and one or more processors coupled to the display and the memory. The processors are configured receive an instruction to transfer a set of samples. The set of samples is associated with a priority-instruction and includes a first subset of samples and a second subset of samples. The processors are also configures to transfer the first subset of samples from a second memory to the first memory based on the priority-instruction before transferring the second subset of samples and to transfer the second subset of samples from the second memory to the first memory.

A display driver includes an image processing circuit and a driver circuit. The image processing circuit is configured to: receive input image data corresponding to an input image; generate first subpixel rendered data from a first part of the input image data for a first display region of a display panel using a first setting; and generate second subpixel rendered data from a second part of the input image data for a second display region of the display panel using a second setting different from the first setting. The first pixel layout is different than the second pixel layout. The driver circuit is configured to update the first display region of the display panel based at least in part on the first subpixel rendered data and update the second display region of the display panel based at least in part on the second subpixel rendered data.

According to an example, a system for electronic display illumination comprises a display, a sensor communicatively coupled to the display to detect a user and a user eye gaze, and a processing resource communicatively coupled to the sensor. In some examples, the processing resource may determine an active screen area and an inactive screen area of the display based on the user eye gaze; instruct a display controller to adjust a display value of the inactive screen area; and transmit active screen area data to a secondary display.

A method to improve display performance at edges of a circular display screen is provided. The method comprises determining an edge area and a central area of the circular display screen, the edge area surrounding the central area; along a direction from a geometric center of the circular display screen to the edge area of the circular display screen, dividing the edge area into n display regions each having a different luminance-level, where n is a positive integer larger than 1; and according to luminance of pixels in the central area and the luminance-level of each of the n display regions, adjusting the luminance of the pixels in each of the n display regions to corresponding target luminance. Along the direction from the geometric center to the edge area of the circular display screen, the corresponding target luminance of the pixels in the n display regions sequentially decreases.

A display device is provided, the display device includes a first display portion, a second display portion not in a same plane with the first display portion, and a side display portion connected between the first display portion and the second display portion, a brightness of the second display portion is less than a brightness of the first display portion and a brightness of the side display portion.

A display substrate, a method for driving the same, a display device, and a high-precision metal mask are provided. The display area includes a first display sub-area in which pixels are distributed at a high density (e.g., a high resolution), and a second display sub-area in which pixels are distributed at a low density (e.g., a low resolution), and a transition display sub-area, with a distribution density of pixels (a resolution) between the distribution density of pixels in the first display sub-area and a distribution density of pixels in the second display sub-area, is arranged between the first display sub-area and the second display sub-area.
