Light sensor beneath a dual-mode display
First Claim
Patent Images
1. A method comprising:
- obtaining a correspondence between a sensor placed beneath a selectively addressable region of a dual-mode display and the selectively addressable region;
causing the dual-mode display to become opaque when displaying a display image;
determining a portion of the display image visible to a user by making a measurement by the sensor while the dual-mode display is displaying the display image;
based on the determination of the portion of the display image visible to the user, reducing consumption of computational resources by displaying the portion of the display image visible to the user; and
during said making the measurement by the sensor, causing the selectively addressable region to stop displaying the display image, such that the selectively addressable region is substantially unnoticeable to the user.

Abstract
The technology disclosed here integrates a light sensor with a dual-mode display, thus increasing the size of the dual-mode display. The light sensor can be a camera, an ambient sensor, a proximity sensor, etc. The light sensor is placed beneath the dual-mode display and can detect incoming light while the dual-mode display is displaying a display image. The dual-mode display and the light sensor can operate at the same time. For example, a camera placed beneath the dual-mode display can record an image of the environment, while at the same time the dual-mode display is showing the display image. Further, multiple light sensors can be placed at various locations beneath the dual-mode display.

15. A method comprising:
-
combining a dual-mode display with a lens, wherein the dual-mode display can be transparent or opaque; placing a sensor beneath a selectively addressable region of the dual-mode display and the selectively addressable region; configuring the dual-mode display to become opaque when displaying a display image; determining a portion of the display image visible to a user by making a measurement by the sensor while the dual-mode display is displaying the display image; based on the determination of the portion of the display image visible to the user, reducing consumption of computational resources by displaying the portion of the display image visible to the user; and during said making the measurement by the sensor, causing the selectively addressable region to stop displaying the display image, such that the selectively addressable region is substantially unnoticeable to the user. - View Dependent Claims (16, 17, 18, 19, 20)
