Abstract

A dual display including: a first display for displaying first visual information and receiving a touch input; a second display including a double-sided emission display for displaying second visual information through a first surface or a second surface opposite to the first surface, and receiving a touch input; a sensor for sensing relative locations of the first and second displays; and a controller for determining whether or not the second display is covering the first display according to a signal of the sensor, and for controlling the first and second displays. Here, the controller is configured to receive the touch input from the second display when the second display unit covers the first display, and to receive the touch input from the first display when the second display does not to cover the first display.

Claims

1. A dual display apparatus comprising:

a first display configured to display first visual information and comprising a first touch unit;

a second display comprising;

a second touch unit; and

a transparent display configured to display second visual information and comprising a first surface and a second surface opposite to the first surface;

a sensor configured to sense relative locations of the first display and the second display; and

a controller configured to determine whether or not the second display is covering the first display according to a signal of the sensor, and configured to control the first display and the second display,

wherein the sensor comprises;

a first sensor at one side of the first display to face the second display when the second display covers the first display; and

a second sensor at one side of the second display to face the first display when the second display covers the first display, and

wherein the controller is configured to detect an angle between the first display and the second display according to signals received from the first sensor and the second sensor.

2. The dual display apparatus of claim 1, wherein the transparent display comprises a double-sided emission type display.

3. The dual display apparatus of claim 1, wherein the controller is further configured to receive a touch input from the second display when the second display covers the first display, and to receive a touch input from the first display when the second display does not cover the first display.

4. The dual display apparatus of claim 1, wherein the second touch unit is on the first and second surfaces of the transparent display.

5. The dual display apparatus of claim 1, wherein the second display is coupled to the first display and configured to rotate and move with respect to the first display.

6. The dual display apparatus of claim 1, wherein the first sensor and the second sensor comprise gyro sensors.

7. The dual display apparatus of claim 1, wherein the controller is further configured to activate one of the first display or the second display and to inactivate another one of the first display or the second display when the second display covers the first display, and configured to activate both the first display and the second display when the second display does not to cover the first display.

8. The dual display apparatus of claim 7, wherein the controller is further configured to inactivate the first display, to activate the second display, and to control the second display to display menu icons when the second display covers the first display.

9. The dual display apparatus of claim 1, further comprising:

a sound sensor configured to sense a sound signal for controlling the dual display apparatus.

10. The dual display apparatus of claim 9, wherein the controller is further configured to activate the first display, to inactivate the second display, and to control the sound sensor to be activated when the second display covers the first display.

11. The dual display apparatus of claim 1, wherein the controller is further configured to activate the first display and the second display to output third visual information by overlapping the first visual information and the second visual information when the second display covers the first display.
