Abstract

A terminal and a method for charging and discharging is described. The terminal includes a first hardware system and a second hardware system. The first hardware system includes a first processing unit, a first charging unit, a first switching unit, and a first battery unit. The second hardware system includes a second processing unit and a second battery unit. On the basis of a first status information piece and/or a second status information piece, the first processing unit controls the first charging unit to charge the first battery unit and/or the second battery unit via the first switching unit, or, the first processing unit controls the first switching unit to select the first battery unit or the second battery unit to supply the first hardware system with electricity.

Claims

1. A mobile terminal, comprising:

a first display unit provided on a first surface of the mobile terminal for displaying first data along a first direction with respect to the mobile terminal in a first space status;

a second display unit provided on a second surface of the mobile terminal, for displaying second data along a second direction with respect to the mobile terminal in a second space status,

wherein, the first direction and the second direction are perpendicular to each other, and

the first surface and the second surface are two different outer surfaces of the mobile terminal.

2. The mobile terminal according to claim 1, wherein, the first direction and the second direction being perpendicular to each other comprises the first direction and the second direction are perpendicular to each other with respect to the mobile terminal with a tolerance.

3. The mobile terminal according to claim 1, further comprising:

a first sensor for determining the space status of the mobile terminal;

a control unit for controlling the display mode of the first or the second display unit according to the space status determined by the first sensor.

4. The mobile terminal according to claim 3, wherein, controlling the display mode of the first or the second display unit according to the space status determined by the first sensor comprises:

controlling on or off of the first display unit according to the space status determined by the first sensor, and

controlling on or off of the second display unit according to the space status determined by the first sensor.

5. The mobile terminal according to claim 3, wherein, controlling the display mode of the first or the second display unit according to the space status determined by the first sensor comprises:

controlling the first or the second direction according to the space status determined by the first sensor.

6. The mobile terminal according to claim 3, wherein, the first sensor determines the space status of the mobile terminal by detecting the angle of rotation of the mobile terminal with respect to a predetermined space status,

the mobile terminal further comprises a second sensor for determining an angle between the mobile terminal and the gravity direction,

the control unit further controls the first direction and/or the second direction according to the angle determined by the second sensor.

7. The mobile terminal according to claim 1, further comprising:

a receiving unit for receiving the first data and the second data.

8. The mobile terminal according to claim 1, further comprising:

a receiving unit for receiving the data to be displayed, and

a processing unit for processing the data to be displayed to obtain the first data and the second data.

9. The mobile terminal according to claim 1, wherein

the first surface and the second surface are two opposite outer surfaces of the mobile terminal.

10. A display method for a mobile terminal having a first display unit and a second display unit, the method comprising the following steps:

receiving the data to be displayed;

processing the data to be displayed according to a preset to obtain first data having a first type and second data having a second type, wherein, the first type and the second type are different; and

displaying the first data in the first display unit and displaying the second data in the second display unit.

11. The method according to claim 10, wherein

the first type is a text type,

the second type is an image type.

12. The method according to claim 10, wherein,

a first display unit is provided on a first surface of the mobile terminal for displaying first data along a first direction with respect to the mobile terminal in a first space status;

a second display unit is provided on a second surface of the mobile terminal, for displaying second data along a second direction with respect to the mobile terminal in a second space status,

wherein, the first direction and the second direction are perpendicular to each other, and

the first surface and the second surface are two different outer surfaces of the mobile terminal.

13. The method according to claim 12, further comprising:

determining the space status of the mobile terminal;

controlling the display mode of the first or the second display unit according to the determined space status.

14. The method according to claim 13, wherein, controlling the display mode of the first or the second display unit according to the determined space status comprises:

controlling on or off of the first display unit according to the space status determined by the first sensor, and

controlling on or off of the second display unit according to the determined space status.

15. The method according to claim 13, wherein, controlling the display mode of the first or the second display unit according to the determined space status comprises:

controlling the first or the second direction according to the determined space status.

16. The method according to claim 13, wherein, determining the space status of the mobile terminal comprises determining the space status of the mobile terminal by detecting the angle of rotation of the mobile terminal with respect to the predetermined space status,

the method further comprising:

determining the angle between the mobile terminal and the gravity direction; and

controlling the first direction and/or the second direction according to the angle between the determined first direction and/or the second direction and the gravity direction.
