Description

  The present invention generally relates to a mobile device, and more specifically to a mobile device configured by two housings rotatably attached.

  2. Description of the Related Art Conventionally, portable devices that can fold an upper housing and a lower housing represented by a mobile phone have been widely used. In addition, as an auxiliary display unit for the main display unit that cannot be viewed with the upper and lower casings closed, a sub display unit is provided at a position facing the main display unit, such as the back of the upper casing and the hinge unit. There is a known device that displays basic information and the like of the device.

  FIG. 18 shows a conventional mobile phone.

  FIG. 18A shows an external view in a state where the upper and lower cases are opened, and FIG. 18B shows an external view in a state where the upper and lower cases are closed.

  In general, as shown in the figure, one housing 101 is provided with a main display 113, a speaker 104, and the like, and the other housing 102 is provided with an operation button, a microphone 104, and the like.

  In the mobile phone, in order to display the device status that the user always wants to know, such as the electric field strength, the remaining battery level, and the clock, a predetermined area is secured on the main display unit 113 as shown in FIG. The status of is displayed. This predetermined display area 113b is generally referred to as a pict display line, and the display for the pict display line is referred to as a pict display.

  However, the pictogram display line divides the display unit 113 that displays the main application into a display area 113a and a display area 113b and displays the display area 113b on the display area 113b or a part of the display area 113b superimposed on the display area 113a. I am letting.

  For this reason, depending on the application, the main display area 113a is reduced by performing pictogram display, and the liquid crystal size may not be fully utilized. In the case of partial superimposition, the main display area 113a is displayed through the pictographic display row 113b, but part of the data is not visible due to pictographic display.

  On the other hand, the size of the main display unit 113 is limited in consideration of portability. Recently, models capable of reproducing moving images are widely used, and it is desired to use the liquid crystal size effectively as a display area. However, there is a problem that these demands cannot be sufficiently satisfied by pictographic display.

  For example, in the case where the sub display unit 114 can be viewed in parallel with the main display unit 113 as described above, a pictographic display is temporarily displayed on the sub display unit 114 by pressing the switching button in the open state. Some of them are known to be hidden or hidden. However, in this case, a predetermined key operation is required to save the pictogram display, and there is a problem that the operability cannot be improved. In addition, the main display unit 113 and the sub display unit 114 cannot be viewed in parallel in the folded state.

  Thus, in the mobile phone 1, the housing 8 is provided to be rotatable. Therefore, when shooting a subject using the camera unit, the user can select the orientation of the first display unit 13 in accordance with the shooting conditions.

  Referring to FIG. 6, after rotating the housing 8 to the state shown in FIG. 5, the housing 8 is rotated about the rotation shaft 5. Thereby, in the mobile phone 1, the surface 8a on which the first display unit 13 is provided faces the outside, and the surface 8b faces the inside while the first display unit 13 and the second display unit 14 are arranged in parallel on the same plane. Closed to face.

  In this specification, the state in which the first display unit 13 and the second display unit 14 shown in FIGS. 5 and 6 are arranged in parallel on the same plane is referred to as a parallel state, and the other state is referred to as a non-parallel state.

  Referring again to FIG. 1, the mobile phone of the present invention has state detection means 30 in the first housing 2 and the second housing 6. The state detection means 30 detects switching between a parallel state in which the first display unit 13 and the second display unit 14 can be viewed in parallel and a non-parallel state which is the other state. The state detection means 30 of this embodiment includes a first Hall element 30a, a second Hall element 30b, a third Hall element 30c, a first magnet 30d, and a second magnet 30e.

  The first hall element 30 a and the second hall element 30 b are provided in the housing 2. The position is, for example, below the key operation unit 18 on the opposite side of the protrusion 4. The third Hall element 30 c is provided at the end of the hinge portion 7 that contacts the housing 8.

  The first magnet 30d and the second magnet 30e are provided in the housing 8. For example, the first magnet 30d is near the speaker 17 on the opposite side of the hinge portion 7, and the second magnet 30e is close to the third hall element 30c. Provided at the end of the housing 8 on the hinge 7 side. The first magnet 30d is disposed at a position close to the first Hall element 30a or the second Hall element 30b in a closed state, and the second magnet 30e is close to the third Hall element 30c in an opened state as shown in FIG. Place in position. The first and second Hall elements 30a and 30b are turned on / off by the magnetic force of the first magnet 30d, and the third Hall element 30c is turned on / off by the magnetic force of the second magnet 30e. Since the Hall element only needs to be able to sense the magnetic force of the magnet, the state detection means 30 does not have to be exposed on the surfaces of the housings 2 and 6 and may be provided in the housings 2 and 6.

  In the present embodiment, the magnet and the Hall element have been described as examples of the state detection means. It may be a pressure-sensitive element made of a semiconductor element to be converted into a switch or another switch.

  An example of the relationship between the Hall element and the open / close state will be described. The first Hall element 30a is turned on by sensing the magnetic force of the first magnet 30d. That is, when the first hall element 30a is on, the first display unit 13 is closed so as to be inside, and this is referred to as a first state (see FIG. 2).

  When the first hall element 30a and the second hall element 30b are in the off state without being close to the first magnet 30d, and the third hall element 30c is in the on state by sensing the magnetic force of the second magnet 30e, the key operation unit 18 and the 1st display part 13 are the states opened so that visual recognition was possible from the same surface side, and this is called a 2nd state (refer FIG. 1).

  In addition, the display orientation of the first display unit 13 with respect to the housing 8 in this state (that is, in a state where normal viewing with the key operation unit 18 is possible) is referred to as a normal image. That is, the display direction in which the speaker 17 direction is “top” and the hinge 7 direction is “ground” is a normal image.

  When all of the first Hall element 30a, the second Hall element 30b, and the third Hall element 30c are off, the housing 2 and the housing 6 are opened and the housing 8 is rotated. (Refer to FIG. 5).

  When only the second hall element 30b is on, the housing 8 is rotated and the housing 6 is closed, which is referred to as a fourth state (see FIG. 6). In this state, the first display unit 13 and the second display unit 14 are exposed to the outside and can be visually recognized even in the closed state. When the third state is changed to the fourth state, the hinge portion 7 is upward and the speaker 17 is downward. Therefore, in the fourth state, the first display unit 13 and the second display unit 14 display in a display orientation in which the direction of the hinge unit 7 is “top” and the speaker direction is “ground”.

  In this way, the display direction is also reversed with respect to the first display unit 13 whose top and bottom are reversed with respect to the second state around the hinge portion 7, so that the user can operate normally without changing the mobile phone even in the fourth state. It can be visually recognized. This display direction is referred to as a reverse image with respect to the normal image.

  In the above states, the parallel state means the third state or the fourth state. At this time, the 1st, 2nd display parts 13 and 14 are displayed in parallel on the same surface side, and the visual recognition from the same surface side is attained.

  The non-parallel state refers to the first state or the second state. At this time, the first and second display units 13 and 14 are not displayed in parallel on the same surface side, but can be visually recognized on one surface side as either the first display unit or the second display unit. A state where the state is not a parallel state in the middle of the transition is also set as a non-parallel state.

  FIG. 7 is a block diagram showing an outline of the configuration of the mobile phone 1. The cellular phone device 1 according to the present embodiment mainly includes a control unit 21, a memory 23, a display driver 24, a first display unit 13, a second display unit 14, a wireless unit 25, a communication control unit 26, a camera unit 27, A key operation unit 18, an antenna 12, and a state detection means 30 are provided.

  The control unit 21 controls the operation of each part constituting the mobile phone 1, and controls, for example, the camera unit 27, the memory 23, the display driver 24, the first and second display units 13 and 14, the communication control unit 26, and the like. To do. For example, when there is an instruction to display image data from the user, the control unit 21 transmits a control signal to the display driver 24 and transmits predetermined image data stored in the memory 23 to the display driver 24.

  The display driver 24 receives a signal from the control unit 21 and applies to each pixel electrode of the first and second display units 13 and 14 according to image data to be displayed on the first and second display units 13 and 14. Apply the drive voltage.

  The camera unit 27 includes an imaging lens 10, an imaging device such as a charge coupled device (CCD) image sensor or a complementary metal oxide semiconductor (CMOS) image sensor, and RGB color filters. The light reflected by the subject and incident on the imaging lens 10 is converted into RGB three-color light through a color filter, and the RGB three-color light is converted into an electrical signal by the image sensor.

  The camera unit 27 amplifies an electrical signal corresponding to RGB, converts the amplified electrical signal (analog) corresponding to RGB into a digital signal, outputs image data, and outputs pixel data to the image data. Signal processing such as interpolation processing is performed. Then, based on the control signal sent from the control unit 21, the image data subjected to signal processing is sent to the memory 23.

  As described above, the key operation unit 18 includes a cross key for moving and enlarging / reducing the display image.

  The antenna 12 transmits and receives voice data, character data, image data, and the like when performing wireless communication with the base station via wireless radio waves. The wireless unit 25 demodulates data received from the base station via the antenna 22 at the time of reception, and modulates and amplifies character data and image data sent from the communication control unit 26 at the time of transmission, Transmit to the base station via the antenna 12. The communication control unit 26 sends received data such as character data and image data demodulated by the wireless unit 25 to the control unit 21 based on a predetermined communication protocol. Received data from the other party received via the wireless unit 25 and the communication control unit 26 is stored in the memory 23.

  As described above, the state detection unit 30 detects the fourth state from the first state by the Hall elements 30a to 30c and the magnets 30d and 30e.

  Furthermore, the control unit 21 of the present embodiment includes display control means 35. The display control means 35 acquires the opening and closing and rotation states of the casings 2 and 6 detected by the state detection means 30, and in accordance with the state, the related data of the data displayed on the first display unit 13 is 2 is displayed on the display unit 14. The data displayed on the first display unit 13 is deleted from the first display unit 13 and displayed on the second display unit 14. Further, it is deleted from the second display unit 14 again according to the state of the casing, and is displayed again on the first display unit 13. Further, the data of the first display unit 13 and the second display unit 14 is subjected to processing such as switching between normal image and reverse image, and a control signal is transmitted to the display driver 24.

  With reference to FIG. 8, the 1st display part 13, the 2nd display part 14, and display data are demonstrated. 8A shows a non-parallel state (second state), and FIGS. 8B and 8C show a parallel state (third and fourth states). The third state is a view seen from the display units 13 and 14 side.

  As shown in FIG. 8A, in the non-parallel state, the first display unit 13 includes at least two display areas, a display area 13a and a display area 13b. The display area 13a is a main display area that serves as a finder when displaying an application or shooting a still image or a moving image, and the display area 13b is an area (pict display line) for performing pictographic display, for example.

  The display area 13b may be provided as an area divided from the display area 13a as shown in the figure, or may be an area secured by partially overlapping the display area 13a.

  The pictogram display is a display of the basic state of the device that the user always wants to know, such as the electric field strength, the remaining battery level, and the clock. In addition, in this specification, for example, an icon display for notification of incoming mail / phone is also included.

  Further, in addition to pictographic display in the display area 13b, shooting information such as shooting date and time and shooting time during still image or moving image shooting as related data in the display area 13a, and playback time and the like when playing back a moving image, etc. Is also displayed. Furthermore, an operation guide key associated with the input key or the operation key may be displayed.

  Here, shooting information, playback time, or operation guide key display other than the basic state of the device may be displayed in a display area that is further separated from the display area 13 b in the first display unit 13. However, in this specification, the display area other than the display area 13a will be described as an example of two areas as the display area 13b.

  The display content of the second display unit 14 changes according to the open / close state of the housing. For example, although illustration is omitted, only basic information is pictically displayed on the second display unit 14 in a state where the casing is closed and the first display unit 13 is not visible (first state). Play an important role. In the non-parallel state of FIG. 8A, the second display unit 14 is turned off.

  In this embodiment, as shown in FIGS. 8B and 8C, in the parallel state (the third state or the fourth state), related data of data displayed on the first display unit 13 is displayed on the second display unit. indicate. The related data is the data attribute information of the data displayed on the first display unit 13 as well as the above-mentioned pictogram display data, other data displayed in the display area 13b, and data displayed in the display area 13b. This is information associated with the data of the first display unit 13 (note that, in the following, a pictographic display will be mainly described as an example, and specific examples of related data will be described later).

  That is, when the state detection unit 30 detects the third state or the fourth state, the display control unit 35 deletes all or part of the pictogram display displayed in the display area 13b of the first display unit 13, and 2 is displayed on the display unit 14. That is, the first display unit 13 can automatically use the display area 13a and the display area 13b as one display area according to the state of the housing without performing key operations, and the liquid crystal size of the first display unit 13 can be changed. Can be used in full size.

  Further, the state detection means includes a first parallel state (third state: FIG. 8B) due to the rotation of the housing 8 and a second parallel state (fourth state: FIG. 8 (FIG. 8) due to the rotation and folding of the housing 8. C)) is detected. The display control means changes the normal image data displayed on the first and second display units 13 and 14 in the first parallel state to the reverse image data in the second parallel state.

  When folded from the third state to the fourth state, the top and bottom of the display is reversed for the user holding the mobile phone if the display direction with respect to the housing 8 remains the same. Therefore, by automatically displaying the display data of the first display unit 13 and the second display unit 14 in reverse image, the user can normally view both display units without changing the mobile phone 1. Thereby, the normal image data is displayed to the user holding the mobile phone 1 in any of the second, third, and fourth states.

  Since the third state is often the user's own photographing, this state may be detected and displayed in a mirror display.

  An example of the display control flow of the present embodiment will be described with reference to FIGS. FIG. 9 is a flowchart, and FIG. 10 is an example of the first and second display units 13 and 14 in each state.

  First, the control unit 21 determines whether there is a change in the first to third Hall elements (step S1), and if there is a change, determines the state of the first Hall element (step S2). Since the first hall element is in the first state, the display control unit 35 transmits a control signal to the display driver 24 to turn off the first display unit 13 (step S3). Then, the display control unit 35 turns on the second display unit 14 and transmits a control signal to the display driver 24 so as to display a basic device status display on the second display unit 14 in reverse (step S4). The basic device status display includes, for example, the remaining battery level, radio wave status, clock, incoming call notification, and the like (FIG. 10A).

  When the first hall element is off, the control unit 21 determines the state of the second hall element (step S5). When the second Hall element is on, it is in the fourth state. In this case, since the state is actually changed from the second state, the third state to the fourth state, the display control means 35 turns on the first display unit 13 to display the reverse image of the data, and the display area 13b is pictographed. Remove the display. The first display unit 13 displays the data on the entire screen with the display areas 13a and 13b as one display area (step S6). Further, the display control means 35 also turns on the second display unit 14, and displays the pictographic display removed from the first display unit 13 on the second display unit 14 (step S7).

  Further, for example, when the operation guide key is displayed in the display area 13b in the second state and the third state, and the key operation in the fourth state is not particularly required, the key is displayed on the first display unit 13. The operation guide key may be deleted and the second display unit 14 may not display the operation guide key. That is, instead of displaying all the data deleted from the first display unit 13 in the parallel state on the second display unit 14, it is preferable to select and display necessary information according to the state (FIG. 10B). ).

  When the first and second Hall elements are off, the control unit 21 determines the state of the third Hall element (step S8). Since the third Hall element is in the second state, the display control means 35 turns on the first display unit 13 to display the data as a normal image, and displays the data in the display area 13b (step S9). Moreover, since the 2nd display part 14 turns into a back surface in this case, it turns off (step S10) (FIG.10 (C)).

  Since the first to third Hall elements are in the third state, the display control means 35 turns on the first display unit 13 and displays data as a normal image. Further, the pictographic display is removed from the display area 13b, and the data is displayed on the full screen with the display areas 13a and 13b as one display area (step S11). Further, the display control unit 35 turns on the second display unit 14 to display the pictogram display removed from the first display unit 13 as a normal image (step S12) (FIG. 10D).

  At this time, the key operation unit 18 and the first and second display units 13 and 14 are on the opposite side, and the camera lens 10 and the display units 13 and 14 are on the same side. For example, when the user takes a picture of himself / herself, the first display unit 13 may be a normal image and may be a mirror display.

  The example in which the pictographic display is automatically moved to the second display unit 14 according to the open / closed state of the housing has been described above. However, as described above, the data displayed on the second display unit 14 in the present embodiment is the pictographic display. However, other related data may be displayed. Hereinafter, an example of data and related data displayed on the first and second display units 13 and 14 will be described with reference to FIG. In each figure, the first and second display units 13 and 14 in parallel are shown on the left side, and a correspondence table of display examples is shown on the right side.

  FIG. 11C: The data displayed on the first display unit 13 is data classified in a plurality of layers, and as related data, data on the upper or lower layer of the data displayed on the first display unit 13 When displaying.

  The contents of the selected folder are displayed on the first display unit 13, and the folder list of the upper hierarchy is displayed on the second display unit 14. Alternatively, the folder list is displayed on the first display unit 13, and the contents of the folder (lower layer folder or file) selected by the cursor are displayed on the second display unit 14.

  In this way, if only the data of the current layer can be displayed on the first display unit in the non-parallel state, the data of the upper or lower layer that was not displayed can be simply displayed by setting the parallel state, and the data is stored. The situation can be made easier to see.

  As mentioned above, although an example of the data displayed on the 1st display part 13 and the 2nd display part 14 was shown, not only this but the data with big information amount are displayed on the 1st display part 13, and it is related with the data, and The amount of information is relatively small, and important information can be displayed on the second display unit 14.

  In addition to moving part of the data displayed on the first display unit to the second display unit, information that cannot be displayed on the first display unit 13 in a non-parallel state, such as a folder hierarchy, is placed in a parallel state. Thus, the second display unit 14 can be used for display.

  Further, in the first embodiment described above, the display of the second display unit 14 is not performed in a state where the key operation unit 18 and the first display unit 13 are opened so as to be visible from the same plane side (second state). However, the present invention is not limited to this. For example, in the shooting mode using the camera unit 27, a message indicating that shooting is in progress may be displayed. With such a configuration, It is possible to make the subject side recognize that shooting is in progress.

  Further, in the first embodiment described above, when the parallel state (third and fourth states) of the first display unit 13 and the second display unit 14 is detected, the related data of the first display unit 13 automatically. Is displayed on the second display unit 14, but when the user performs an operation in this parallel state (third and fourth states), the second display unit 14 is not displayed, The related data of the first display unit 13 displayed on the display unit 14 may be displayed on the first display unit 13. With such a configuration, it is possible to reduce power consumption in the second display unit 14 when the first display unit 13 does not need to be largely used without impairing the convenience of the user. Can extend the usage time.

For example, when there is no user operation or application execution operation for a predetermined time or longer, the display by the first display unit 13 may be interrupted. With such a configuration, power consumption in the first display unit 13 can be reduced, the usage time of the portable device can be extended, and the pictorial information on the second display unit 14 can be continuously displayed. is there. In order to interrupt the display by the first display unit 13, the backlight is turned off when the first display unit 13 is configured by a liquid crystal display, the drive of the first display unit 13 is stopped, the running application is forcibly terminated, etc. These operations may be performed simultaneously, or each operation may be performed in stages.

  Next, a second embodiment will be described with reference to FIGS. The second embodiment is a mobile phone having a rotation / folding mechanism similar to that of the first embodiment, and has a structure in which the second display unit 14 is arranged on the protrusion 4.

  This structure also includes a first housing 2 and a second housing 6 that is pivotally connected to the first housing 2 around a rotation shaft 5. The housing 2 includes a base portion 3 having a substantially rectangular surface 3a and a protruding portion 4 formed to protrude from a predetermined position on the surface 3a, and a second display portion is disposed on the protruding portion as shown in the figure. The The second housing 6 includes a hinge portion 7 and a housing 8, and the shape of the mobile phone 1 is shown in FIG. 12 by moving the second housing 6 with respect to the first housing 2 so as to be angularly displaceable. 14 and the open state shown in FIG. 14 and the closed state shown in FIGS. 13 and 15.

  In the second embodiment, the second display unit 14 is fixed to the first housing 2 side, and even if the second housing 6 is rotated with respect to the first housing 2, the second display unit 14. The structure itself does not rotate.

  That is, since the second display unit 14 is provided on the surface of the projecting portion 4, the screen of the second display unit 14 is exposed even when the housing 6 is closed with respect to the housing 2 and can be visually recognized as it is. It is.

  In this case, since the arrangement of the second display unit 14 is different, the determination of the display control unit is different, but the state detection unit and other components and operations of the mobile phone are the same as in the first embodiment. The description is omitted.

  With reference to FIGS. 12 to 15, the open / close state of the housing and the first and second display units will be described.

  1st state (FIG. 13): It is the state folded so that the housing | casing 6 was closed and the 1st display part 13 might become inside. Only the second display unit 14 is turned on, and the data of the second display unit 14 is displayed in a normal image so that the hinge unit 7 is on the upper side and the microphone 20 is on the lower side.

  2nd state (FIG. 12): It is the state which opened the key operation part and the 1st display part so that visual recognition was possible from the same surface side, and the 1st display part 13 and the 2nd display part 14 will be in a parallel state. That is, both display units are turned on and displayed as normal images.

  3rd state (FIG. 14): It is the state which rotated the housing | casing 8 180 degree | times, and the 1st display part 13 and the 2nd display part 14 will be in a non-parallel state. In this case, the lens 10 of the camera and the first display unit 13 are on the same surface side, and the photographer can shoot confidence. In this case, only the first display unit 13 is turned on to display a normal image. Moreover, it is good also as a mirror image display with a normal image.

That is, both display units are turned on, and the first display unit 13 is displayed in reverse image. Since the second display unit 14 is fixed to the housing 2, it is a normal image display.

  FIG. 16 shows an example of the display control flow, and FIG. 17 shows a schematic diagram of the mobile phone 1 in each state.

  First, the controller 21 determines whether there is a change in the first to third Hall elements (Step S11), and if there is a change, determines the state of the first Hall element (Step S12). Since the first hall element is in the first state when it is on, the display control means 35 turns off the first display unit 13 (step S13). Then, the second display unit 14 is turned on, and the basic device status display is displayed as a normal image on the second display unit 14 (step S14). The basic device status display includes, for example, the remaining battery level, radio wave status, clock, incoming call notification, and the like (FIG. 17A).

  When the first hall element is off, the control unit 21 determines the state of the second hall element (step S15). When the second Hall element is on, the display control means 35 turns on the first display unit 13 to display the image in reverse image and removes the pictographic display from the display area 13b because it is in the fourth state. As a result, the first display unit 13 displays the data on the entire screen with the display areas 13a and 13b as one display area (step S16). Further, the display control unit 35 also turns on the second display unit 14, and displays the pictographic display removed from the first display unit 13 as a normal image on the second display unit 14 (step S17).

  Further, for example, when the key operation in the fourth state is not particularly required, the operation guide key pictically displayed on the first display unit 13 is deleted, and the operation guide key is not displayed on the second display unit. Also good. That is, instead of displaying all the data deleted from the first display unit 13 in the parallel state on the second display unit 14, it is preferable to select and display information necessary according to the state (FIG. 17B). ).

  When the first and second hall elements are off, the display unit 21 determines the state of the third hall element (step S18). When the third Hall element is on, it is in the second state, so the display control means 35 turns on the first display unit 13 and displays data as a normal image. Further, the pictographic display is removed from the display area 13b, and the data is displayed on the full screen with the display areas 13a and 13b as one display area (step S19). Further, the display control means 35 turns on the second display unit 14 and displays the pictogram display removed from the first display unit 13 as a normal image (step S20) (FIG. 17C).

  Since the first to third Hall elements are in the third state, the display control means 35 turns on the first display unit 13 to display the data as a normal image and pictically displays it on the display area 13b ( Step S21). At this time, the key operation unit 18 and the first display unit 13 are opposite surfaces. For example, when the user takes a picture of himself / herself, the first display unit 13 may be a normal image and may be a mirror display. Since the second display unit 14 is the back side in this case, it is turned off (step S22) (FIG. 17D).

  In the second embodiment described above, when the parallel state (second state and fourth state) of the first display unit 13 and the second display unit 14 is detected, the association of the first display unit 13 is automatically performed. The data is displayed on the second display unit 14, but when there is a user operation in this parallel state (second and fourth states), the second display unit 14 is not displayed, The related data of the first display unit 13 displayed on the second display unit 14 may be displayed on the first display unit 13. With such a configuration, it is possible to reduce power consumption in the second display unit 14 when the first display unit 13 does not need to be largely used without impairing the convenience of the user. Can extend the usage time.

  In the second embodiment described above, when the parallel state (second and fourth states) of the first display unit 13 and the second display unit 14 is detected, the related data of the first display unit 13 is automatically displayed. Although it is made to display on the 2nd display part 14, it is not limited to this. For example, the display of the second display unit 14 is performed in a state where the first display unit 13 is closed so as to be inside (first state), and in the other states (second to fourth states), the second display is performed. Display on the display unit 14 is not performed, and related data of the first display unit 13 is displayed on the second display unit 14 when a user operation is performed in the parallel state (second and fourth states). You may do it. With such a configuration, when it is not necessary to use the first display unit 13 largely, power consumption in the second display unit 14 can be reduced, and the usage time of the portable device can be extended.

  Furthermore, in the above-described second embodiment, information is displayed on both the first display unit 13 and the second display unit 14 in a state where the first display unit 13 is closed so as to be on the outside (fourth state). However, the present invention is not limited to this. For example, when there is no user operation or application execution operation for a predetermined time or longer, the display by the first display unit 13 may be interrupted. With such a configuration, the power in the first display unit 13 can be reduced. Consumption can be reduced, the usage time of the portable device can be extended, and there is also an advantage that the pictogram information on the second display unit 14 can be continuously displayed. The display interruption by the first display 13 includes turning off the backlight, stopping the driving of the first display unit 13 and forcibly terminating the running application when the first display unit 13 is configured by a liquid crystal display.
