Samsung patents chip that combines camera and screen
Samsung has been granted a patent for a semiconductor device that stacks an image sensor directly under a display panel. The design uses vertical connection paths to link camera pixels to screen pixels, allowing the device to capture and show video in a single component.
In the filing’s own words
Provided is a semiconductor device for video transmission display including a display unit including a plurality of light emitting elements constituting a plurality of unit display pixels, an image sensor unit disposed on the display unit so that the plurality of unit image sensor pixels corresponding to the same color and the plurality of unit display pixels overlap each other at least partially in a vertical direction, and a plurality of connection paths each including at least one through electrode and electrically connecting the plurality of unit image sensor pixels corresponding to the same color to the plurality of unit display pixels.
What exactly they claim (claim 1)
1. A semiconductor device for video transmission display, the semiconductor device comprising: an image sensor unit including a semiconductor substrate, a plurality of light sensing elements in the semiconductor substrate and constituting a plurality of unit image sensor pixels, a first wiring structure on a first surface of the semiconductor substrate, the first wiring structure including a plurality of first wiring patterns and a first inter-wiring insulating layer surrounding the plurality of first wiring patterns, a plurality of color filter layers on a second surface of the semiconductor substrate such that the plurality of color filter layers at least partially overlap corresponding light sensing elements of the plurality of light sensing elements, and a plurality of microlenses on the plurality of color filter layers; a display unit including a second wiring structure on the first wiring structure and including a plurality of second wiring patterns and a second inter-wiring insulating layer surrounding the plurality of second wiring patterns, and a plurality of light emitting elements on the second wiring structure and constituting a plurality of unit display pixels; and a plurality of connection paths electrically connecting each of the plurality of unit image sensor pixels to a corresponding one of the plurality of unit display pixels, the plurality of connection paths each including at least one through electrode.
