Systems and methods described herein may utilize a non-linear scaling relationship to scale brightness of selective portions of the display in a manner that reduces or eliminates perceivable banding effects. By non-linearly controlling changes in brightness of the display, a viewer may perceive a more uniform, linear dimming towards the relatively dimmer region without perceiving banding, leading to improved user experience when viewing the electronic display.

Display panel brightness control based on gaussian edges

An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To increase the apparent resolution of the display in portions of the display panel with the transparent windows, the display may include a light spreading layer that includes a plurality of diffractive elements. The light spreading layer may spread visible light from the array of pixels such that the display resolution at the outer surface of the display is greater than at the display panel. The light spreading layer may selectively spread visible light but not infrared light. The display may also include a lens layer that focuses light onto the transparent windows.

Devices with displays having transparent openings and a diffractive layer

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.
