Electronic devices with light sensors and displays
First Claim
1. An electronic device, comprising:
- a light sensor; and
a display formed over the light sensor, the display comprising;
a substrate layer;
a first electrode layer;
a second electrode layer;
a layer of organic emissive material between the first electrode layer and the second electrode layer; and
a layer of light-blocking material interposed between the first electrode layer and the light sensor, wherein the layer of light-blocking material comprises an opening that is aligned with the light sensor, and wherein the light sensor receives light through the opening in the layer of light-blocking material.

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.
