  • Publication number: 20220199046
    Abstract: Example systems and related methods for adjusting a backlight of a display based on a position of a viewer are disclosed. In an example, the system includes a display including an outer surface, and a backlight assembly to emit light in a direction that is perpendicular to the outer surface. In addition, the system includes a controller coupled to the backlight. The controller to adjust a brightness of light emitted from a first portion of the backlight assembly relative to a brightness of light emitted from a second portion of the backlight assembly to provide a substantially uniform brightness for the display at a position of the viewer relative to the display.

  • Publication number: 20220050314
    Abstract: In example implementations, a display is provided. The display includes a collimated back light unit (BLU) comprising a light guide plate and a plurality of light emitting diodes (LEDs), a polymer dispersed liquid crystal (PDLC) layer formed over the collimated BLU, a thin film transistor (TFT) substrate, a liquid crystal layer formed over the TFT substrate, a color filter (CF) substrate, and a controller. The PDLC layer is to provide selective privacy areas on the display. The TFT substrate is to control emission of light from the plurality of LEDs. The CF substrate is to control a color of the light emitted from the plurality of LEDs. The controller is communicatively coupled to the plurality of LEDs and the POLO layer to activate a selected area of the PDLC layer to enable a privacy area on a corresponding area that is selected on the display.

  • Publication number: 20220011607
    Abstract: Example electronic devices including a display are disclosed. In an example, the display includes a backlight, and an image generator to form an image from light emitted from the backlight. In addition, the display includes a first privacy panel and a second privacy panel disposed between the backlight and the image generator. The first privacy panel includes a first set of parallel lines, and the second privacy panel includes a second set of parallel lines that are perpendicular to the first set of parallel lines. The first set of parallel lines is to actuate to selectively adjust a first viewing angle of the display in a first plane, and the second set of parallel lines is to actuate to selectively adjust a second viewing angle of the display in a second plane that is perpendicular to the first plane.
