Abstract

A mobile computing device is disclosed for displaying backlight and diffuse reflecting information. The mobile computing device is configured to include a processor, a first LCD display unit connected to the processor, and a second diffuse reflecting display unit connected to the processor. The mobile computing device is further provided with a display panel interface, such as a mouse or a gravity detecting device like an accelerometer, configured to detect a property for activating a display type. The processor is configured to send information to be displayed to the first display unit or the second display unit or both depending on the display type property detected.

Claims

1. A terminal, comprising;

a display part comprising;

a backlit display unit;

a diffuse reflecting display unit configured to display a dashboard of information with life data of the terminal that is always visible;

a keyboard part;

a swivel member connecting the display part to the keyboard part to allow the display part of the terminal to swivel about an orthogonal axis of the swivel member when the display part is substantially orthogonal to the keyboard part of the terminal such that in a first position of the display part, the backlit display unit is allowed to face in a direction of the keyboard part of the terminal and in a second position of the display part, the diffuse reflecting display unit is allowed to face in the direction of the keyboard part of the terminal;

a sensor configured to detect a property for activating a display type; and

wherein the terminal is configured to send information to be displayed to the backlit display unit or the diffuse reflecting display unit or both depending on the property detected by the sensor.

2. The terminal of claim 1, wherein the diffuse reflecting display unit is based on e-ink technology.

3. The terminal of claim 1, wherein:

the sensor is a touch activated sensor comprising a first touch activated sensor associated with the backlit display unit and a second touch activated sensor associated with the diffuse reflecting display unit;

wherein the property detected by the touch activated sensor is a touch detected by the first touch activated sensor or a touch detected by the second touch activated sensor; and

wherein the touch detected by the first touch activated sensor activates the backlit display unit and the touch detected by the second touch activated sensor activates the diffuse reflecting display unit.

4. The terminal of claim 1, wherein the sensor is a gravity detecting device and the property detected for activating the display type depends on which of the backlit display unit or the diffuse reflecting display unit is facing in an upward direction.

5. The terminal of claim 1, comprising a memory configured to store properties of the backlit display unit and the diffuse reflecting display unit.

6. The terminal of claim 1, wherein the diffuse reflecting display unit is configured to serve as a mouse pad or a mouse.

7. The terminal of claim 1, wherein the backlit display unit and the diffuse reflecting display unit are located on a front side of the terminal.

8. The terminal of claim 1, wherein the diffuse reflecting display unit overlays the backlit display unit.

9. The terminal of claim 1, wherein the backlit display unit overlays the diffuse reflecting display unit.

10. The terminal of claim 1, wherein a display unit comprising one of the backlit display unit and the diffuse reflecting display unit facing toward the keyboard part of the terminal is used in a first set of operations.

11. The terminal of claim 10, wherein the display unit facing away from the keyboard part of the terminal is used in a second set of operations.

12. The terminal of claim 11, wherein the second set of operations that are being performed using the display unit facing away from the keyboard part of the terminal are performed contemporaneously with the first set of operations that are being performed using the display unit facing toward the keyboard part of the terminal.

13. The terminal of claim 11, wherein the display unit facing away from the keyboard part of the terminal is configured to provide a display face of the terminal when the display part is closed onto the keyboard part of the terminal.

14. The terminal of claim 13, wherein the display face of the terminal serves as a tablet when the display part is closed onto the keyboard part of the terminal.

15. A method, comprising:

detecting, with a sensor in a terminal, a property for activating a display type;

sending information to be displayed to a backlit display unit of the terminal or a diffuse reflecting display unit of the terminal or both depending on the property detected;

wherein the diffuse reflecting display unit is configured to display a dashboard of information with life data of the terminal that is always visible;

wherein the terminal comprises;

a display part comprising the backlit display unit and the diffuse reflecting display unit;

a keyboard part; and

a swivel member connecting the display part to the keyboard part to allow the display part of the terminal to swivel about an orthogonal axis of the swivel member when the display part is substantially orthogonal to the keyboard part of the terminal such that in a first position of the display part, the backlit display unit is allowed to face in a direction of the keyboard part of the terminal for use in a first set of operations and in a second position of the display part, the diffuse reflecting display unit is allowed to face in the direction of the keyboard part of the terminal.

16. The method of claim 15, wherein (i) the sensor comprises a first touch activated sensor associated with the backlit display unit and a second touch activated sensor associated with the diffuse reflecting display unit and (ii) detecting, with the sensor in the terminal, the property for activating a display type comprises detecting a touch with the first touch activated sensor or detecting a touch with the second touch activated sensor, the method comprising:

in response to detecting a touch with the first touch activated sensor, activating the backlit display unit; and

in response to detecting a touch with the second touch activated sensor, activating the diffuse reflecting display unit.

17. A terminal, comprising;

a processor;

a display part comprising;

a first display unit configured to provide a backlit display connected to the processor; and

a second display unit configured to provide a diffuse reflecting display connected to the processor and display a dashboard of information with life data of the terminal that is always visible on account of the diffuse reflecting display holding its data;

a display panel interface configured to detect a property for activating a display type;

a keyboard part;

a swivel member connecting the display part to the keyboard part of the terminal to allow the display part of the terminal to swivel about an orthogonal axis of the swivel member when the display part is substantially orthogonal to the keyboard part of the terminal;

wherein the processor is configured to send information to be displayed to the first display unit or the second display unit or both depending on the display type property detected; and

wherein the display panel interface is a sensor and the property detected for activating the display type is a property detected by the sensor;

wherein the swivel member allows, in a first position of the display part, the first display unit to face in a direction of the keyboard part of the terminal for use in a first set of operations and in a second position of the display part, the second display unit is allowed to face in the direction of the keyboard part of the terminal.

18. The terminal of claim 17, wherein the diffuse reflecting display is based on e-ink technology.

19. The terminal of claim 17, wherein:

the sensor is a touch activated sensor comprising a first touch activated sensor associated with the backlit display and a second touch activated sensor associated with the diffuse reflecting display;

wherein the property detected by the touch activated sensor is a touch detected by the first touch activated sensor or a touch detected by the second touch activated sensor; and

wherein the touch detected by the first touch activated sensor activates the backlit display and the touch detected by the second touch activated sensor activates the diffuse reflecting display.
