Abstract

A dual image display device, including a first screen display; a second screen display overlapping the first screen display and including a transparent display; and a driving controller to control the second screen display, the second screen display selectively transmitting and displaying an image of the first screen display according to control of the driving controller.

Claims

1. A dual image display device, comprising:

a first screen display;

a second screen display overlapping the first screen display and including a transparent display; and

a driving controller to control the second screen display,

the second screen display selectively transmitting and displaying an image of the first screen display according to control of the driving controller.

2. The dual image display device as claimed in claim 1, wherein the first screen display displays one or more of a clock, global positioning system (GPS) location information, contact information, or health information.

3. The dual image display device as claimed in claim 2, wherein the first screen display is an organic light emitting device (OLED).

4. The dual image display device as claimed in claim 2, wherein the first screen display is an analog watch including an hour hand and a minute hand.

5. The method as claimed in claim 4, wherein the controller includes:

a first driving mode that allows the image of the first screen display to be transmitted and displayed through the transparent display of the first screen display; and

a second driving mode that forms an image on the transparent display such that the image of the second screen display is displayed.

6. The method as claimed in claim 5, wherein the first driving mode is an operation off state of the transparent display.

7. The method as claimed in claim 5, wherein the second driving mode is an operation on state of the transparent display.

8. The dual image display device as claimed in claim 1, further comprising a frame body surrounding edges of the first screen display and the second screen display and simultaneously fixing the first screen display and the second screen display together.

9. The dual image display device as claimed in claim 8, wherein a band portion to be worn on a portion of a user body is connected to sides of the frame body.

10. The dual image display device as claimed in claim 1, wherein the second screen display is a transparent liquid crystal display (LCD), a transparent thin film electroluminescent panel (TFEL), or a transparent OLED.

11. The dual image display device as claimed in claim 1, wherein a light-transmitting passivation layer is attached to a surface of the second screen display.

12. The dual image display device as claimed in claim 11, wherein the light-transmitting passivation layer includes a glass or plastic material.

13. A method for driving a dual image display device, including a first screen display, a second screen display overlapping the first screen display and including a transparent display, and a driving controller to control the second screen display, the second screen display selectively transmitting and displaying an image of the first screen display according to control of the driving controller, the method comprising:

allowing the image of the first screen display to be transmitted through the second screen display by making the transparent display transparent;

selecting, by the driving controller, a driving mode of the second screen display; and

forming an image on the transparent display to display an image of the second screen display.

14. The method as claimed in claim 13, wherein the controller produces:

a first driving mode that allows the image of the first screen display to be transmitted and displayed through the transparent display of the first screen display; and

a second driving mode that forms the image on the transparent display such that the image of the second screen display is displayed.

15. The method as claimed in claim 14, wherein the first driving mode is an operation off state of the transparent display.

16. The method as claimed in claim 14, wherein the second driving mode is an operation on state of the transparent display.
