Electronic devices with light sensors and displays

摘要

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.

主权项

1. An electronic device, comprising:
an enhanced translucency display having a layer of reflective material having a first translucency enhancement feature and a thin-film transistor layer having a second translucency enhancement feature, wherein the first and second translucency enhancement features allow light to pass through the enhanced translucency display; a light sensor configured to receive the light that passes through the first and second translucency enhancement features; and masking material interposed between the layer of reflective material and the light sensor, wherein the masking material comprises an opening that is aligned with the first and second translucency enhancement features.
