Abstract: An organic light-emitting diode display may have an active area that contains pixels and an inactive area. The inactive area of the display may be provided with opaque masking layer structures having an appearance that matches the active area of the display when the pixels are off and are not displaying images. The opaque masking layer structures may include a polymer layer coated with a layer of metal. The display may have pixels with anodes and a cathode layer. The anodes may be formed from metal pads. Dummy structures such as a dummy cathode and dummy anodes may be formed in the inactive area. A circular polarizer in the display may overlap the active area and the inactive area or may overlap the active area without overlapping some or all of the inactive area.

Abstract: An electronic device includes a transparent surface, a light emitting device that emits light through the transparent surface, and a light sensor for receiving ambient light and providing an ambient light value. A retarder and a linear polarizer are placed between the transparent surface and the light emitting device. The retarder and linear polarizer may attenuate internal reflections from the transparent surface. The light sensor may have two channels and a second linear polarizer may attenuate the ambient light directed toward a second channel. A second retarder may be used with the second linear polarizer to attenuate the ambient light directed toward the second channel. A light detection circuit may use the difference between the two channels of the light sensor to provide the ambient light value.
