Electronic devices with light sensors and displays
First Claim
1. An electronic device having a display and a light sensor mounted beneath the display, the display comprising:
- a substrate;
a first electrode layer formed on the substrate;
a layer of organic emissive material formed on the first electrode layer;
a second electrode layer formed on the layer of organic emissive material such that the layer of organic emissive material is interposed between the first and second electrode layers, wherein the second electrode layer comprises conductive traces having modified portions that are aligned with the light sensor to allow for light to pass through the second electrode layer onto the light sensor; and
a layer of light absorbing material interposed between the first electrode layer and the light sensor, wherein the layer of light absorbing material comprises openings that are aligned with the modified portions of the conductive traces such that the light passes through the openings and between the modified portions of the conductive traces onto the light sensor.

Abstract
An electronic device is provided with a display and a light sensor that receives light that passes through the display. The display includes features that increase the amount of light that passes through the display. The features may be translucency enhancement features that allow light to pass directly through the display onto a light sensor mounted behind the display or may include a light-guiding layer that guides light through the display onto a light sensor mounted along an edge of the display. The translucency enhancement features may be formed in a reflector layer or an electrode layer for the display. The translucency enhancement features may include microperforations in a reflector layer of the display, a light-filtering reflector layer of the display, or a reflector layer of the display that passes a portion of the light and reflects an additional portion of the light.
