Abstract

An electronic device includes a display that includes a first area having a plurality of first pixels arranged with a first density and a second area having a plurality of second pixels arranged with a second density, wherein the display includes at least one layer having an opening formed in at least part of the first area and in at least part of the second area, a first sensor configured to detect incident light through at least part of the first area, and a second sensor configured to generate image data using incident light received through the opening.

Claims (52)

1. An electronic device comprising:

a display including a first area having a plurality of first pixels arranged with a first density and a second area having a plurality of second pixels arranged with a second density, the first area of the display having a lower pixel density than does the second area of the display,

wherein the display includes at least one layer formed in at least part of the first area and in at least part of the second area;

a first sensor configured to detect incident light through at least part of the first area; and

a second sensor configured to generate image data using incident light received through the first area,

at least parts of the first and second sensors being provided in the first area of the display having the lower pixel density,

wherein the first area is not surrounded by the second area,

wherein the at least one layer comprises a cushion layer,

wherein the cushion layer includes a first opening corresponding to the first sensor and a second opening corresponding to the second sensor,

wherein the second opening is larger than the first opening,

wherein the second sensor comprises a light receiving sensor,

wherein the first sensor is at least partially overlapped with at least one sub-pixel included in the plurality of first pixels, and

wherein the second sensor is not overlapped with the at least one sub-pixel.

2. The electronic device of claim 1 , wherein the display further includes a display panel layer.

3. The electronic device of claim 2 , wherein the display further includes a polarization layer.

4. The electronic device of claim 3 , wherein the display further includes a flexible cover glass layer, and

a rigid cover glass layer disposed on the flexible cover glass layer.

5. The electronic device of claim 2 ,

wherein the display panel layer includes a curved area and a substantially flat area, and

wherein at least part of the first sensor is disposed in an area that corresponds to the first area of the display and the curved area.

6. The electronic device of claim 5 , wherein the first opening and the second opening are formed in an area of the at least one layer corresponding to the substantially flat area.

7. The electronic device of claim 5 , wherein the curved area is on a periphery of the display.

8. The electronic device of claim 1 ,

wherein the first opening has a size less than a size of the first sensor as viewed from above.

9. The electronic device of claim 1 , further comprising:

a display driver IC,

wherein the display driver IC is configured to transmit a first image signal to the first area and to transmit a second image signal to the second area.

10. The electronic device of claim 9 , wherein the first image signal includes a signal for indicating a status of the electronic device, and

wherein the second image signal includes a signal for displaying an execution screen of an application.

11. The electronic device of claim 1 , wherein at least some of the first pixels are arranged in a first arrangement having an interval greater than a first distance, and

wherein the second pixels are arranged in a second arrangement having an interval equal to a second distance, the second distance being less than the first distance.

12. An electronic device comprising:

a display including a display panel layer including a first area having pixels arranged in a first structure and a second area having pixels arranged in a second structure, the first area of the display panel layer having a lower pixel density than does the second area of the display panel layer;

a first sensor disposed below the first area; and

a second sensor disposed at least partially in or below the display panel layer and configured to receive light through the first area,

wherein the first area is not surrounded by the second area,

at least parts of the first sensor and the second sensor being provided in the first area of the display panel layer having the lower pixel density,

wherein the display panel layer includes an opening corresponding to the second sensor,

wherein the second sensor comprises a light receiving sensor,

wherein the first sensor is at least partially overlapped with one or more sub-pixels included in the pixels in the first area, and

wherein the second sensor is not overlapped with the one or more sub-pixels.

13. The electronic device of claim 12 , wherein at least part of the first area includes at least one of: an electrode and/or an interconnection wire that is substantially transparent.

14. The electronic device of claim 13 , wherein the at least part of the first area provides a light transmittance over a specified range.

15. The electronic device of claim 12 , wherein the first sensors includes at least one of: a proximity sensor, an illuminance sensor, a gesture sensor, a motion sensor, a fingerprint recognition sensor, and/or a biometric sensor.

16. The electronic device of claim 12 , wherein the display further includes a cushion layer, and

wherein the cushion layer includes a first opening corresponding to the first sensor and a second opening corresponding to the second sensor.

17. The electronic device of claim 16 , wherein

the opening of the display panel layer and the opening of the cushion layer are formed in one body.

18. The electronic device of claim 17 , wherein the display further includes a polarization layer, and

wherein an opening is formed in part of the polarization layer to correspond to the opening of the display panel layer.

19. The electronic device of claim 18 , wherein the display further includes a flexible cover glass layer and a rigid cover glass layer disposed on the flexible cover glass layer, and

wherein an opening is formed in part of the flexible cover glass layer to correspond to the opening of the polarization layer.
