IMAGE CAPTURE WITH A CAMERA INTEGRATED DISPLAY
First Claim
1. A method of capturing an image, comprising:
- initiating, by a processor, light emission from a backlight source to illuminate a liquid crystal display (LCD) layer disposed beneath a color filter (CF) layer and a substantially transparent cover layer,wherein the LCD layer comprises an LCD substrate and a plurality of liquid crystals disposed on the LCD substrate, the plurality of liquid crystals configured to assume a first arrangement and a second arrangement,wherein the light emitted from the backlight source is transmitted through the first arrangement and blocked by the second arrangement;
suspending, by the processor, the light emission from the backlight source for a period of time imperceptible to a human observer; and
initiating, by the processor, a camera to capture an image during the period of time the backlight source is suspended,wherein the camera is disposed beneath the CF layer, and proximate to the LCD layer, the camera comprising a plurality of pixels corresponding to a plurality of color regions associated with the CF layer,wherein each pixel in the plurality of pixels is optimized to record a colored light beam passing through a color region associated with the CF layer,wherein each pixel in the plurality of pixels comprises a lens and a photodetector, wherein the lens associated with the pixel is optimized to focus the colored light beam.

Abstract
Certain aspects of the technology disclosed herein integrate a camera with an electronic display. An electronic display includes several layers, such as a cover layer, a color filter layer, a display layer including light emitting diodes or organic light emitting diodes, a thin film transistor layer, etc. A processor initiates light emission from a plurality of display elements. The processor suspends the light emission from the plurality of display elements for a period of time imperceptible to a human observer. The processor initiates a camera to capture an image during the period of time the plurality of display elements are suspended. The processor can capture a plurality of images corresponding to a plurality of pixels and produce an image comprising depth information.
