    Abstract: A layer of liquid crystal material may be interposed between display layers. The display layers may include thin-film transistor circuitry having subpixel electrodes for applying electric fields to subpixel portions of the layer of liquid crystal material. Subpixels of different colors may have different shapes and may have different liquid crystal layer thicknesses. These subpixel differences may be configured to slow the switching speed of subpixels of a certain color relative to other subpixels to reduce color motion blur when an object is moved across a black or colored background. The subpixels may have chevron shapes. Subpixels of a first color may have chevron shapes that are less bent than subpixels of second and third colors. In configurations with varying liquid crystal layer thicknesses, the subpixels of the first color may have thicker liquid crystal layers than the subpixels of the second and third colors.

    Abstract: Systems and methods for reducing or eliminating image artifacts on a dual-layer liquid crystal display (LCD). By way of example, a system includes a first display panel and a second display panel. The system includes a processor coupled to the first display panel and the second display panel, and configured to generate a first image, and to generate a second image to be displayed on the first display panel based on the first image. The processor is configured to interpolate the second image. Interpolating the second image includes adjusting the second image according to a generated objective function bounded by a first constraint. The processor is configured to filter the second image, and to generate a third image to be displayed on the second display panel based on the first image and the second image. The third image is generated to prevent image artifacts on the second display panel.

    Abstract: Systems and methods for operating a display by dynamically determining a refresh rate for the display. In certain implementations, a processor determines a number of pixels having medium grayscale levels from a histogram for the image. If the number does not exceed a threshold, the processor sets a refresh rate for the display to a first refresh rate. In certain implementations, if the number exceeds a threshold, the processor may set the refresh rate for the display to a second refresh rate. Moreover, the first refresh rate may be lower than the second threshold. In some implementations, the image may be analyzed by subdividing the image into blocks and determining a refresh rate based on grayscale levels or distributions in the blocks. Based on the analysis of the blocks, a corresponding refresh rate may be selected.

    Abstract: An electronic device may include a display having an array of display pixels. The display pixels may include red, green, blue, and white subpixels. Pixel mapping circuitry may convert red-green-blue pixel values in a frame of display data to red-green-blue-white pixel values using a brightness adjustment factor. The brightness adjustment factor may be determined based on ambient lighting conditions. The brightness adjustment factor be determined such that any color distortion resulting from applying the brightness adjustment factor is maintained under a just-noticeable-difference (JND) threshold. White subpixel values may be determined based on the brightness adjustment factor. Pixel rendering circuitry may be used to render red-green-blue-white pixel values onto the physical pixel structure. When a display pixel does not include a subpixel of a particular color, the pixel rendering circuitry may compensate for the missing color using nearby subpixels.

    Abstract: An electronic device may include a display having an array of display pixels and having display control circuitry that controls the operation of the display. The display control circuitry may adaptively adjust the spectral characteristics of display light emitted from the display to achieve a desired effect on the human circadian system. For example, the display control circuitry may adjust the spectral characteristics of blue light emitted from the display based on the time of day such that a user's exposure to the display light may result in a circadian response similar to that which would be experienced in natural light. The spectral characteristics of blue light emitted from the display may be adjusted by adjusting the relative maximum power levels provided to blue pixels in the display or by shifting the peak wavelength associated with blue light emitted from the display.
