  • Patent number: 11882752
    Abstract: An electronic device display may have an active area with pixels. An optical sensor may be formed under a sensor region in the active area. During operation, ambient light and/or other light associated with the optical sensor may pass through the sensor region. To ensure that the light for the optical sensor can pass through the display, the display may have one or more layers with sensor openings such as a metal layer and a pressure sensitive adhesive layer that attaches the metal layer to the pixels of the display. To help minimize visibility of the openings in the sensor region, the pressure sensitive adhesive layer may be configured to have a reflectivity that matches the appearance of the display in the sensor region to surrounding areas. Undesired light output uniformity can be reduced by ensuring that the substrate material in the display has a low light absorption coefficient.

  • Patent number: 11762490
    Abstract: An electronic device may have a display with an active area configured to display images and an inactive area that is free of pixels and that does not display images. Touch sensor sense lines may have portions located in the active area and portions located in the inactive area. The active and inactive areas may be characterized by respective reflectivity values. To match the reflectivities of the active and inactive areas and thereby avoid undesired visually distinguishable differences in the appearances of these areas, the touch sensor circuitry in the inactive areas may be configured to match the reflectivity values of the active and inactive areas. Sense line portions in the inactive area may have metal traces of enhanced reflectivity and/or uneven surface topology to enhance ambient light reflections through a circular polarizer that overlaps the active and inactive areas.
