Abstract

A display device, and a method of operating and manufacturing the display device may receive input light from an object to be scanned that is positioned in front of a display for displaying an image, and may perform scanning of the object to be scanned.

First claim

What is claimed is:

1. A display device, comprising:
a pattern panel comprising display pixels;
a sensor panel configured to sense N images from input light that is received in association with an object to be scanned and is received through a portion of the display pixels, N being a natural number, wherein the portion of the display pixels allows the input light to pass and another portion of the display pixels does not allow the input light to pass;
an image creator configured to create a full image of the object to be scanned based on the N images;
a display controller configured to control at least the portion of the display pixels to emit light toward the object to be scanned, wherein the emitted light is reflected from the object to be scanned, and is converted to the input light;
a front display comprising the pattern panel to display the created full image; and
a rear display positioned on the opposite side of the pattern panel to display at least a portion of the created full image,
wherein the image creator creates the full image of the object to be scanned by partially overlapping adjacent images among the N images, and wherein the pattern panel comprises organic light emitting pixels, each of which comprises an infrared (IR) unit to emit IR light.

2. The display device of claim 1 , wherein the display pixels is arranged based on a predetermined arrangement rule, depending on whether the display pixels allows the input light to pass.

3. The display device of claim 2 , wherein, among the display pixels, a display pixel that does not allow the input light to pass is disposed around a display pixel that allows the input light to pass.

4. The display device of claim 2 , wherein the display pixels are arranged in a modified uniformly redundant array (MURA) pattern.

5. The display device of claim 4 , wherein the image creator creates a depth image of the object to be scanned based on the N images.

6. The display device of claim 1 , wherein the at least a portion of the display pixels comprises a transparent window.

7. The display device of claim 6 , wherein a display pixel, excluding a display pixel comprising the transparent window from among the display pixels, comprises an opaque window.

8. The display device of claim 6 , wherein the sensor panel senses the N images from the input light that is received through a display pixel comprising the transparent window among the display pixels.

9. The display device of claim 1 , wherein the display pixels comprises an organic light emitting diode pixel.

10. The display device of claim 1 , further comprising:
a light emitter to emit light toward the object to be scanned.

11. The display device of claim 1 , wherein the control is configured to display the full image on at least a portion of a front display or display the full image on a rear display based on a position of the object to be scanned.

12. The display device of claim 1 , wherein a number of imagining patterns is determined based on a size of a front display to receive the input light, a number objects to be scanned, and positions thereof.

13. A display device, comprising:
a pattern panel comprising display pixels;
a substrate disposed below the pattern panel;
a sensor panel disposed below the substrate configured to sense N images from input light that is received through a portion of the display pixels, N being a natural number, wherein the portion of the display pixels allows the input light to pass and another portion of the display pixels does not allow the input light to pass;
a display controller configured to control at least the portion of the display pixels to emit light toward the object to be scanned, wherein the emitted light is reflected from the object to be scanned, and is converted to the input light,
an image creator to create a full image of the object by partially overlapping adjacent images among the N images;
a front display comprising the pattern panel to display the created full image; and
a rear display positioned on the opposite side of the pattern panel to display at least a portion of the created full image, and wherein the pattern panel comprises organic light emitting pixels, each of which comprises an infrared (IR) unit to emit IR light.

14. The display device of claim 13 , wherein the pattern panel further comprises a thin film transistor (TFT) array.

15. The display device of claim 14 , wherein each of the organic light emitting diode pixels comprises one of a transparent window and an opaque window.

16. A method of operating a display device, the method comprising:
sensing N images from input light that is received in association with an object to be scanned and is received through a portion of display pixels, N being a natural number, wherein the portion of the display pixels allows the input light to pass and another portion of the display pixels does not allow the input light to pass;
creating a full image of the object to be scanned based on the N images; and
displaying the created full image in a front display comprising a pattern panel, and displaying at least a portion of the created full image in a rear display positioned on the opposite side of the pattern panel,
controlling at least a portion of the display pixels to emit light toward the object to be scanned using an infrared (IR) unit to emit IR light, wherein the emitted light is reflected from the object to be scanned, and is converted to the input light,
wherein the creating comprises creating the full image of the object to be scanned by partially overlapping adjacent images among the N images.

17. The method of claim 16 , further comprising:
displaying at least a portion of the created full image on a rear display that is positioned on an opposite side of the display pixels.

18. A non-transitory computer readable recording medium storing a program to implement the method of claim 16 .

19. A method of manufacturing a display device, the method comprising:
forming a pattern panel comprising display pixels;
forming a substrate disposed below the pattern panel; and
forming a sensor panel disposed below the substrate to sense N images from input light that is received through a portion of the display pixels, N being a natural number, wherein the portion of the display pixels allows the input light to pass and another portion of the display pixels does not allow the input light to pass;
controlling at least a portion of the display pixels to emit infrared (IR) light, using an IR unit, toward the object to be scanned, wherein the emitted light is reflected from the object to be scanned, and is converted to the input light,
creating a full image of the object to be scanned by partially overlapping adjacent images among the N images; and
displaying the created full image in a front display comprising the pattern panel, and displaying at least a portion of the created full image in a rear display positioned on the opposite side of the pattern panel.

20. The method of claim 19 , wherein the pattern panel comprises organic light emitting diode pixels and a thin film transistor (TFT) array.

21. The method of claim 20 , wherein each of the organic light emitting diode pixels comprises one of a transparent window and an opaque window.

22. A method for capturing an image using a display screen, the method comprising:
capturing an image on a sensor panel by receiving light that has passed through a transparent display pixel in a display panel comprising t
