Abstract: A display may have display layers such as liquid crystal display layers having a liquid crystal layer interposed between a color filter layer and a thin-film transistor layer or organic light-emitting diode layers having organic light-emitting diodes formed from thin-film transistor circuitry. The display layers may be configured to form an array of pixels that display images and may include a polarizer. An angle-of-view adjustment layer may overlap the display layers. The angle-of-view adjustment layer may include one or more liquid crystal layers. A first polarizer may be interposed between first and second liquid crystal layers and the second liquid crystal layer may be overlapped by a second polarizer. The first and second polarizers may have pass axes that are aligned with a pass axis of the polarizer in the display layers. One or more liquid crystal layers in the angle-of-view adjustment layer may include dichroic dye.

Abstract: A display may have display layers that form an array of pixels. The display layers may include a first layer that includes a light-blocking matrix and a second layer that overlaps the first layer. The first layer may include quantum dot elements formed in openings in the light-blocking matrix. The light-blocking matrix may be formed from a reflective material such as metal. The second layer may include color filter elements that overlap corresponding quantum dot elements in the first layer. Substrate layers may be used to support the first and second layers and to support thin-film transistor circuitry that is used in controlling light transmission through the array of pixels. The display layers may include a liquid crystal layer, polarizer layers, filter layers for reflecting red and green light and/or other light to enhance light recycling, and layers with angularly dependent transmission characteristics.

By way of example, a display panel includes a data driver, which includes a first DAC configured to provide an internal gamma voltage signal to cause a first adjustment to an image data signal. The first adjustment is configured to selectively adjust the image data signal based at least in part on a refresh rate or a frame rate of the display panel. The data driver includes a second DAC coupled to the first DAC and configured to provide an external gamma voltage signal configured to provide a second adjustment to the image data signal, and an output buffer configured to supply the image data signal to pixels of the display panel, wherein the image data signal comprises the first adjustment and the second adjustment.

Abstract: A display may include an optical film to promote sunglass-friendly viewing of the display. Displays may include linear polarizers. For example, a liquid crystal display may have a linear polarizer above a liquid crystal layer, whereas an organic light-emitting diode display may have a linear polarizer that forms a portion of a circular polarizer to reduce reflections in the display. Displays that emit linearly polarized light may not be compatible with polarized sunglasses. To ensure an optimal user experience for users wearing sunglasses, displays may include sunglass-friendly optical films. A sunglass-friendly optical film may be a film formed from a birefringent material such as a polymer or liquid crystal. The sunglass-friendly optical film may have an optical axis that is at a 45° angle relative to the optical axis of the underlying linear polarizer. The sunglass-friendly optical film may be patterned to have reduced thickness regions.

Abstract: System and method for improving displayed image quality of an electronic display that displays a first image frame by applying a first voltage to a display pixel and a second image frame directly before the first image frame by applying a second voltage to the display pixel. A display pipeline is communicatively coupled to the electronic display and receives first image data corresponding with the first image frame, where the image data includes a first grayscale value corresponding with the display pixel. Additionally the display pipeline determines an inversion balancing grayscale offset based at least in part on the first grayscale value when polarity of the first voltage and polarity of the second voltage are the same and determines magnitude of the first voltage by applying the inversion balancing grayscale offset to the first grayscale value to reduce likelihood of a perceivable luminance spike when displaying the first image frame.

Abstract: A system such as a vehicle, building, or electronic device system may have a support structure with one or more windows. The support structure and window may separate an interior region within the system from a surrounding exterior region. Control circuitry may receive input such as user input and may adjust an adjustable layer in the window based on the input. The adjustable layer may have a polymer matrix layer with embedded cells. The cells may include intermixed guest-host liquid crystal cells and liquid crystal cells. The guest-host liquid crystal cells and liquid crystal cells may have different liquid crystal materials and/or different sizes that allow the guest-host liquid crystal cells and liquid crystal cells to electrically switch states at different respective threshold voltages. Based on the user input or other input the control circuitry can adjust a drive signal across the adjustable layer to change light transmittance and haze.
