Samsung patents display that captures HDR images using built-in light sensors

Samsung describes an electronic device with a display that contains both light-emitting pixels and light-receiving pixels. The device uses different voltage levels to read data from two separate groups of these light-receiving pixels to create a high dynamic range (HDR) image.

Why it mattersThis approach could allow devices to capture detailed images with better contrast without needing a separate camera sensor, potentially improving screen-based photography or scanning features.

In the filing’s own words

An electronic device including: a display device; memory storing instructions; and at least one processor including processing circuitry, wherein the display device includes: a pixel layer including: light-emitting pixels; and light-receiving pixels including: first-group light-receiving pixels; and second-group light-receiving pixels; and a lens layer on the pixel layer and including lenses respectively corresponding to the light-receiving pixels, and wherein the at least one processor individually or collectively executes the instructions to cause the electronic device to: obtain, by applying a first driving voltage to the first-group light-receiving pixels and applying a second driving voltage having a voltage value different from a voltage value of the first driving voltage to the second-group light-receiving pixels: first light-reception signals from the first-group light-receiving pixels; and second light-reception signals from second-group light-receiving pixels; and generate an HDR image based on the first light-reception signals and the second light-reception signals.

What exactly they claim (claim 1)

1. An electronic device comprising: a display device; memory storing instructions; and at least one processor comprising processing circuitry, wherein the display device comprises: a pixel layer comprising: a plurality of light-emitting pixels; and a plurality of light-receiving pixels comprising: first-group light-receiving pixels; and second-group light-receiving pixels; and a lens layer on the pixel layer and comprising a plurality of lenses respectively corresponding to the plurality of light-receiving pixels, and wherein the at least one processor individually or collectively executes the instructions to cause the electronic device to: obtain, by applying a first driving voltage to the first-group light-receiving pixels and applying a second driving voltage having a voltage value different from a voltage value of the first driving voltage to the second-group light-receiving pixels: first light-reception signals from the first-group light-receiving pixels; and second light-reception signals from the second-group light-receiving pixels; and generate a high dynamic range (HDR) image based on the obtained first light-reception signals and the obtained second light-reception signals.
