Abstract

An electronic device is provided. The electronic device includes a display device configured to display an optical image on a front side of the display device. Further, the electronic device includes at least one sensor configured to measure electromagnetic radiation received from a scene in front of the front side of the display device. The display device includes a first display region using a first display technology and exhibiting a first transmissivity for the electromagnetic radiation. The display device further includes a second display region using a second display technology and exhibiting a second transmissivity for the electromagnetic radiation. The first transmissivity is higher than the second transmissivity. The at least one sensor is arranged on a back side of the display device and faces the first display region.

Claims (33)

1. An electronic device, comprising:

a display device configured to display an optical image on a front side of the display device; and

at least one sensor configured to measure electromagnetic radiation received from a scene in front of the front side of the display device,

wherein the display device comprises a first display region using a first display technology and exhibiting a first transmissivity for the electromagnetic radiation,

wherein the display device further comprises a second display region using a second display technology and exhibiting a second transmissivity for the electromagnetic radiation, the first transmissivity being higher than the second transmissivity, and

wherein the at least one sensor is arranged on a back side of the display device behind the first display region and faces the first display region, such that the display device is arranged between the at least one sensor and the scene.

2. The electronic device of claim 1 , wherein a pixel density of the first display region is equal to a pixel density of the second display region.

3. The electronic device of claim 1 , wherein the first display technology uses micro light emitting diodes, and wherein the second display technology uses organic light emitting diodes.

4. The electronic device of claim 1 , wherein the first display region comprises a plurality of first light-emitting elements configured to display a first part of the optical image on the front side of the display device, and wherein the second display region comprises a plurality of second light-emitting elements configured to display a second part of the optical image on the front side of the display device.

5. The electronic device of claim 4 , wherein the first light-emitting elements are of smaller individual size than the second light-emitting elements.

6. The electronic device of claim 4 , wherein distances between neighboring ones of the second light-emitting elements in the second display region are smaller than distances between neighboring ones of the first light-emitting elements in the first display region.

7. The electronic device of claim 4 , wherein a number of the first light-emitting elements per unit area in the first display region is equal to a number of the second light-emitting elements per unit area in the second display region.

8. The electronic device of claim 4 , wherein each of the first light-emitting elements comprises at least one respective micro light emitting diode, and wherein each of the second light-emitting elements comprises at least one respective organic light emitting diode.

9. The electronic device of claim 4 , wherein the display device comprises a third display region, wherein the third display region comprises a mixed arrangement of the first light-emitting elements and the second light-emitting elements.

10. The electronic device of claim 1 , wherein the display device comprises a first display using the first display technology and a second display using the second display technology, wherein the second display extends over the second display region, wherein a recess is formed in the second display so that the second display does not extend into the first display region, and wherein the first display is arranged on a backside of the second display and faces the recess.

11. The electronic device of claim 1 , wherein the electronic device comprises a plurality of sensors, wherein the first display region comprises a plurality of sub-regions, and wherein the plurality of sensors is arranged on the back side of the display device facing different ones of the plurality of sub-regions.

12. The electronic device of claim 1 , wherein the at least one sensor is an optical sensor, and wherein the electromagnetic radiation comprises light.

13. The electronic device of claim 1 , wherein the at least one sensor is one of a radar sensor and a radio frequency receiver, and wherein the electromagnetic radiation comprises radio waves.

14. The electronic device of claim 1 , further comprising at least one emitter configured to emit the electromagnetic radiation, wherein the at least one emitter is arranged on the back side of the display device and faces the first display region.

15. The electronic device of claim 1 , wherein the electromagnetic radiation comprises infrared light, and wherein the first display region comprises at least one light-emitting element configured to emit the infrared light for illuminating the scene.

16. The electronic device of claim 1 , wherein the at least one sensor is a Time-of-Flight (ToF) sensor.

17. The electronic device of claim 1 , wherein the first display region and the second display region are formed on separate substrates.

18. An electronic device, comprising:

a display device configured to display an optical image on a front side of the display device; and

at least one sensor configured to measure electromagnetic radiation received from a scene in front of the front side of the display device,

wherein the display device comprises a first display using a first display technology,

wherein the display device further comprises a second display using a second display technology,

wherein the first display is more transparent for electromagnetic radiation than the second display,

wherein the first display and the second display are separate displays,

wherein a recess is formed in the second display,

wherein the first display is arranged on a backside of the second display and faces the recess,

wherein the at least one sensor is arranged behind the first display and faces the first display.

19. The electronic device of claim 18 , wherein the recess is filled with a transparent material.
