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: This disclosure relates to image capture devices with the ability to perform adaptive white balance correction using a switchable white reference (SWR). In some embodiments, the image capture device utilizes “true white” information to record images that better represent users' perceptions. In other embodiments, the same SWR and camera that dynamically sample ambient lighting conditions are used to determine “true white” in near real-time. In other embodiments, the image capture device comprises a display screen that utilizes the “true white” information in near real-time to dynamically adjust the display. In other embodiments, face detection techniques and/or ambient light sensors may be used to determine which device camera is most closely-aligned with the direction that the user of the device is currently looking in, and using it to capture a “true white” image in the direction that most closely corresponds to the ambient lighting conditions that currently dominate the user's perception.

The electronic display includes display driver circuitry that display an image frame on the electronic device using a first display pixel and a second display pixel, touch sensing circuitry that detect user interaction with the electronic display, and a timing controller. The timing controller receives image data, in which the image data describes a target grayscale value of the first pixel and the second pixel to display the image frame, instructs the display driver circuitry to display a first portion of the image frame by writing the image data to the first display pixel, instructs the touch sensing circuitry to determine whether a user touch is present on a surface of the electronic display after the first portion of the image frame is displayed, determines grayscale value displayed by the second display pixel to display a previous image frame, and instructs the display driver circuitry to display a second portion of the image frame by writing adjusted image data to the second display pixel when the displayed grayscale value differs from the target grayscale value of the second pixel by more than a threshold amount.

Abstract: A display may have an array of pixels. The display may be controlled using display driver circuitry. The display driver circuitry may analyze image data to be displayed on the array. When static content is detected, the rate at which the pixels are refreshed may be adjusted to conserve power. If a static image is detected, the gate lines may be asserted at a lower refresh rate than if moving content is detected. To avoid visible artifacts, the display driver circuitry may use temporal and spatial refresh rate buffers. Temporal buffers ensure that refresh rates are changed gradually as a function of time, thereby minimizing flicker. Spatial refresh rate buffers are used to provide a smooth transition between low refresh rate and high refresh rate regions in a display as a function of position.

Abstract: A display polarizer may have a polymer layer such as a polyvinyl alcohol layer coated with a dichroic dye such as iodine. A polymer layer such as a tri-acetyl cellulose layer may be formed on the polyvinyl alcohol layer so that the iodine is interposed between the polyvinyl alcohol layer and the tri-acetyl cellulose layer. To provide protection for the iodine layer, an additional polymer layer such as an additional tri-acetyl cellulose layer and a layer of adhesive may be formed on top of the polymer layer. A functional layer such as an antireflection layer may form an outermost layer in the polarizer. Compensation films may be formed beneath the polyvinyl alcohol layer. Additional display layers such as a lower polarizer layer and interposed layers such as a thin-film transistor layer, liquid crystal layer, and color filter layer may be formed below the compensation films.

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.
