DETAILED DESCRIPTION
Hereinafter, the preferred embodiments of the invention are described in detail with reference to the accompanying drawings. It is noticed that in the specification and accompanying drawings, substantially same steps and elements are represented by same reference numbers, and the repetitive explanation on these steps and elements would be omitted.
Hereinafter, the mobile terminal of the embodiment of the invention is explained with reference to FIG. 1. FIG. 1 is an exemplary block view showing the structure of the mobile terminal 100 according to the embodiment of the invention. As shown in FIG. 1, the mobile terminal 100 of the embodiment comprises; a first display unit 110 and a second display unit 120. The first display unit 110 and the second display unit 120 may comprise display screens of same type, and may comprise display screens of different types. For example, the first display unit 110 may comprise a display screen of type such as TFT, OLED or the like, and the second display unit 120 may comprise a display screen of low power consumption such as a display screen of type of Memory LCD, E-Ink or the like.
As shown in FIG. 1, the first display unit 110 is provided on the first surface 1100 of the mobile terminal 100, and may be used to display first data along a first direction with respect to the mobile terminal 100 in a first space status. The second display unit 120 is provided on a second surface 1200 of the mobile terminal 100, and may be used to display second data along a second direction with respect to the mobile terminal 100 in a second space status, for example, the first space status may be a space status of the first surface 1100 facing the user when the user holds the mobile terminal 100. The second space status may be a space status of the second surface 1200 facing the user when the user holds the mobile terminal 100. In the first space status and the second space status, the bodies of the mobile terminal 100 may be perpendicular to each other with respect to the user. Further, the first direction in the first space status and the second direction in the second space status of the mobile terminal can be preset. Alternatively, the current space status of the mobile terminal can be determined by providing a sensor in the mobile terminal, so as to execute corresponding operation according to the result of the determination. The first space status and the second space status of the mobile terminal are described in detail hereinafter.
The first direction and the second direction are perpendicular to each other. However, as understood by those skilled in the art, due to the reason such as fabricating process or the like, the perpendicularity in the embodiment is not absolute. The first direction and the second direction being perpendicular to each other may comprise the first direction and the second direction being perpendicular to each other with a tolerance, for example, an error of ±5 degree or ±10 degree is allowed.
Further, in the embodiment of the invention, the first data and the second data may be data of same type, and may be data of different types. For example, the first data may be text data and the second data may be image data, or both of the first, data and the second data are text data or image data. And the image data may be still image data, and may be motion image data, for example video stream. And, the first data and the second data may be data of same type with same content.
Further, the first surface 1100 and the second surface 1200 may be two different outer surfaces of the mobile terminal 100. For example, the first surface 1100 and the second surface 1200 are two opposite outer surfaces of the mobile terminal 100. Alternatively, the first surface 1100 and the second surface 1200 are two adjacent outer surfaces of the mobile terminal 100.
According to the embodiment of the invention, it can display with two display units under different space statuses of the mobile terminal, and when the user carries out switch under two space statuses, the finger holding the mobile terminal need not to move with respect to the mobile terminal, and it only need the rotation of the wrist. Thereby, the switch of the space statuses is more convenient, and at the same time it can prevent slip-out of the mobile terminal caused by such relative movement, and the watching experience of the user is improved.
Hereinafter it will explain taking the first surface and the second surface as the two opposite outer surfaces of the mobile terminal as example. FIG. 2a and FIG. 2b are schematic views showing the first surface 2100 and the second surface 2200 of the mobile terminal 200 according to the embodiment of the invention. FIG. 2a is a front view perspective of the mobile terminal 200, and FIG. 2b is a back view perspective of the mobile terminal 200. As shown in FIG. 2a and FIG. 2b, in a reference coordinate system with the mobile terminal 200 as reference (for example, as shown in FIG. 2a, the bottom left corner of the first surface in the front view perspective is the origin O of the coordinate system, and it is same for the following figures), it assumes that the width direction of the mobile terminal 200 is X-axis, and the thickness direction is Y-axis, and the height direction is Z-axis. The first display unit 210 is provided on the first surface 2100 of the mobile terminal 200, and the second display unit 220 is provided on the second surface 2200 of the mobile terminal 200. The first surface 2100 and the second surface 2200 are two opposite outer surfaces of the mobile terminal 200.
Hereinafter, the first space status and the second space status of the mobile terminal 200 will be described in detail with reference to FIG. 3a and FIG. 3b and FIG. 4a and FIG. 4b. FIG. 3a and FIG. 3b are schematic views showing one example of the first space status and the second space status of the mobile terminal 200. In this embodiment, it will explain by taking the first data as text data and the second data as image data as example.
As shown in FIG. 3a, when the mobile terminal 200 is in the first space status, the first surface 2100 faces the user longitudinally (for example, Z-axis upward). The first display unit 210 displays the first data along the negative direction of Z-axis in a plane on which X-axis and Z-axis are under the first space status, i.e., as shown by the arrow 310 in FIG. 3a. 
As shown in FIG. 3b, the mobile terminal 200 is rotated by 90 degree from the first space status with Y-axis as axis of rotation, then the mobile terminal 200 is rotated by 180 degree with the rotated Z-axis as axis of rotation, resulting in the second space status of the mobile terminal 200. That is, in the embodiment, when the user holds the mobile terminal 200 longitudinally with the right hand under the first space status, the user turns the right hand and holds the mobile terminal 200 transversally, so that the mobile terminal 200 is made switch to the second space status from the first space status. While the mobile terminal 200 is in the second space status, the second surface 2200 faces the user transversally (for example, Z-axis leftwards). The second display unit 220 displays the second data along a positive direction of X-axis in a plane on which X-axis and Z-axis are under the second space status, i.e., as shown by arrow 320 in FIG. 3b. In term of the reference. i.e., the mobile terminal 200, the directions shown by the arrow 310 and 320 are perpendicular to each other (i.e., the negative direction of Z-axis is perpendicular to the positive direction of the X-axis).
FIG. 4a and FIG. 4b are schematic views showing another example of the first space status and the second space status of the mobile terminal 200 respectively. Similar to the examples shown in FIG. 3a and FIG. 3b, in the embodiment, it will explain by taking the first data as text data and the second data as image data as example.
As snow in FIG. 4a, when the mobile terminal 200 is in the first space status, the first surface 2100 faces the user transversally (for example, Z-axis leftwards). The first display unit 210 displays the first data along the negative direction of X-axis in a plane on which X-axis and Z-axis are under the first space status, i.e., as shown by the arrow 410 in FIG. 4a. 
As shown in FIG. 4b, the mobile terminal 200 is rotated by 90 degree from the first space status with Y-axis as axis of rotation, then the mobile terminal 200 is rotated by 180 degree with the rotated Z-axis as axis of rotation, resulting in the second space status of the mobile terminal 200. That is, in the embodiment, when the user holds the mobile terminal 200 transversely with the right hand under the first space status, the user turns the right hand and holds the mobile terminal 200 longitudinally, so that the mobile terminal 200 is made switch to the second space status from the first space status. While the mobile terminal 200 is in the second space status, the second surface 2200 faces the user longitudinally (for example, Z-axis upward). The second display unit 220 displays the second data along a negative direction of Z-axis in a plane on which X-axis and Z-axis are under the second space status, i.e., as shown by arrow 420 in FIG. 4b. In term of the reference, i.e., the mobile terminal 200, the directions shown by the arrow 410 and 420 are perpendicular to each other (i.e., the negative direction of X-axis is perpendicular to the negative direction of the Z-axis).
In the embodiments shown in FIG. 3a and FIG. 3b and FIG. 4a and FIG. 4b, the first space status and the second space status of the mobile terminal 200 are interchangeable. For example, the status shown in FIG. 3b may be the first space status, and the status shown in FIG. 3a may be the second space status. Similarly, the status shown in FIG. 4b may be the first space status, and the status shown in FIG. 4a may be the second space status.
Further the embodiments shown in FIG. 3a and FIG. 3b and FIG. 4a and FIG. 4b are only examples of the first space status and the second space status of the mobile terminal. For example, the first space status or the second space status can be symmetrical to the specific space status shown in the FIGS. In such cases, the first direction is still perpendicular to the second direction with respect to the mobile terminal. In one embodiment, when the user holds the mobile terminal 200 longitudinally with the left hand under the first space status shown in FIG. 3a, the user turns over the left hand and holds the mobile terminal 200 transversally, so that the mobile terminal 200 is made switch from the first space status to the second space status (i.e., Z-axis rightwards, the orientations of the X-axis and the Y-axis are same as those in FIG. 3b) that is dot-symmetrical to the status shown in FIG. 3b (being symmetrical with respect to the O point in X-Z plane).
In another embodiment, when it takes the status shown in FIG. 4a as the first space status, and the user holds the mobile terminal 200 transversally with the left hand under such status, the user turns over the left hand and holds the mobile terminal 200 longitudinally, so that the mobile terminal 200 is made switch from the first space status to the second space status (i.e., X-axis rightwards, Z-axis downwards, and the orientation of the Y-axis is same as that in FIG. 4b) mirror-symmetrical to the status shown in FIG. 4b (being symmetrical to the O point in the X-Z plane).
When the user browses a webpage including text data and image data, with the mobile apparatus of the embodiment, text information can be displayed on the first display unit 210, and image information can be displayed on the second display unit 220. In this way, the user can view the content displayed on the webpage clearly only through turning over the wrist.
In an alternative embodiment, the first data and the second data can be both text data. When the text information included in the data displayed to be viewed by the user is relatively more, all of the text information may not be possible to be displayed on the first display unit. In this case, the text information that can not be displayed on the first display unit can be displayed on the second display unit. In this way, the user can view the display data only through turning over the wrist without a page turn operation.
In the mobile terminal of another embodiment of the invention, it further comprises a receiving unit (not show) for receiving the first data and the second data. A first data interface for receiving the first data and a second data interface for receiving the second data can be configured in the receiving unit, in the case that the content provider provides two streams of data of the first data and the second data respectively, the first data and the second data can be received through the first data interface and the second data interface respectively, and provided to the first display unit and the second display unit.
In an alternative embodiment, the mobile terminal may further comprise a receiving unit and a processing unit (not show). The receiving unit may receive the data to be displayed. The processing unit may process the data to be displayed received by the receiving unit to obtain the first data and the second data. In the case that the content provider only provides data to be displayed (for example, the data included in the above webpage) but not classifies it into the first data (for example, the text information) and the second data (for example, the image information), the processing unit may process the data to be displayed according to a preset processing, and provide the obtained first data and second data to the first display unit and the second display unit respectively. In case that the webpage to be displayed includes a relatively large image, the processing unit may compress the image information to obtain the second data. Furthermore, in case that the webpage to be displayed includes dynamic image, the processing unit may treat the dynamic image information as the second data, and may pick out one picture of the dynamic image as the second data.
The direction of display of the first display unit and the second display unit of the mobile apparatus can be preset according to the manner of general rotation of the wrist. For example, in the embodiment shown in FIG. 3a and FIG. 3b, it may preset that the first display unit 210 displays the first data along the negative direction of the Z-axis in the plane on which X-axis and Z-axis are in the operational mode that two display units are turned on to display. The second display unit 220 displays the second data along the positive direction of X-axis in a plane on which X-axis and Z-axis are.
Further, it may be possible to provide a sensor in the mobile apparatus to detect the current space status of the mobile terminal and display according to the detection result. Hereinafter, it will be explained in detail.
Hereinafter, the electronic apparatus according to another embodiment of the invention will be explained with reference to FIG. 5. FIG. 5 is an exemplary block view showing the structure of the mobile terminal according to another embodiment of the invention. As shown in FIG. 5, similar to the electronic apparatus 100, the electronic apparatus 500 comprises a first display unit 510 and a second display unit 520. The first display unit 510 is provided on the first surface 5100 of the mobile terminal 500, and may be used for displaying the first data along the first direction in the first space status. The second display unit 520 is provided on the second surface 5200 of the mobile terminal 500, and may be used for displaying the second data along the second direction in the second space status. The first direction and the second direction are perpendicular to each other with respect to the mobile terminal 500. In the embodiment, the first surface 5100 and the second surface 5200 are two opposite outer surfaces of the mobile terminal 500.
The mobile terminal 500 in the embodiment further comprises a first sensor 530 and a control unit 540. The first sensor 530 can determine the space status of the mobile terminal 500. The first sensor 530 can comprise a gyroscope for detecting the turn of the mobile terminal 500, a terrestrial magnetism sensor for detecting the angle of tilt of the mobile terminal 500 or a photosensor for sensing the motion of the mobile terminal 500 by detecting the variation of the reflected light, etc. The control unit 540 can control the display mode of the first or the second display unit according to the space status determined by the first sensor 530.
It will be described with reference to the embodiments shown in FIG. 3a and FIG. 3b by taking the first sensor 530 comprising a gyroscope for example, it assumes that the first space status of the mobile terminal 500 is shown in FIG. 3a, the second space status is shown in FIG. 3b, and the first space status of the mobile terminal 500 is an initial status of the gyroscope in the first sensor 530. When the first sensor 530 determines that the mobile terminal 500 is in the initial status, the control unit 540 controls the first display unit 510 to display, and control the second display unit 520 to be in close status to save power consumption. Further, when the first sensor 530 determines that the mobile terminal 500 is in the initial status, the control unit 540 can further control the first display unit 510 to display the first data along the negative direction of Z-axis in a plane on which X-axis and Z-axis are.
When the user holds the mobile terminal 500 with the right hand and turns over, the mobile terminal 500 is switched from the first space status to the second space status, the first sensor 530 determines the space status of the mobile terminal 500 by detecting the angle of rotation detected by the gyroscope, that is, the mobile terminal 500 carrying out the turn can be determined by detecting the varied angle of the gyroscope and thus the direction of the turn can be determined. The control unit 540 can control the second display unit 520 to display according to the space status determined by the first sensor 530, and control the first display unit 510 to be in close status to save power consumption. Further; according to the direction of the turn determined, the control unit 540 can further control the second display unit 520 to display the second data along the positive direction of X-axis in a plane on which X-axis and Z-axis are.

When the first sensor 530 determines that the mobile terminal 500 is in the initial status, the control unit 540 controls the first display unit 510 to display, and controls the second display unit 520 to be in close status to save power consumption. Further, when the first sensor 530 determines that the mobile terminal 500 is in the initial status, the control unit 540 can further control the first display unit 510 to display the first data along the negative direction of Z-axis in a plane on which X-axis and Z-axis are.
When the user holds the mobile terminal 500 with the left hand and turns over, the mobile terminal 500 is switched from the first space status to the second space status, the first sensor 530 determines the space status of the mobile terminal 500 by detecting the angle of rotation detected by the gyroscope, that is, the mobile terminal 500 carrying out the turn can be determined by detecting the varied angle of the gyroscope and thus the direction of the turn can be determined. The control unit 540 can control the second display unit 520 to display according to the space status determined by the first sensor 530, and control the first display unit 510 to be in close status to save power consumption. The display unit being in the close status comprises for example turning off the power supply of the display unit; or the display unit being in a sleep status of low power consumption. Further, according to the direction of the turn determined, the control unit 540 can further control the second display unit 520 to display the second data along the negative direction of X-axis in a plane on which X-axis and Z-axis are.
Though in the embodiment, it is described by taking an example that the first sensor 530 determines the space status of the mobile terminal 500 by detecting the angle of rotation of the mobile terminal 500 with respect to the first space status through the gyroscope, the invention is not limited thereto. For example, the first sensor 530 may comprise a gravity sensor, and detect the angle of tilt of the mobile terminal 500 with respect to the gravity direction by the gravity sensor, and the control unit 540 can control the display mode of the first or the second display unit according to the space status determined by the first sensor 530.
Hereinafter, the electronic apparatus according to yet another embodiment of the invention will be explained with reference to FIG. 6.

And the gravity sensor in the second sensor 650 detects that the posture of the body is transversal, so as to determine that the angle between the body of the mobile terminal 600 and the gravity direction is 90 degree. The control unit 640 can control the second display unit 620 to display the second data along the positive direction of X-axis in a plane on which X-axis and Z-axis are and control the first display unit 610 to be in close status to save power consumption according to according to the determination result of the first sensor 630 and the second sensor 650.
