  The Hall element 113a of the present embodiment can output a signal corresponding to the direction of magnetic flux and the magnetic flux density.

  Further, as illustrated in FIGS. 1A and 1B, the arrangement of the magnet 123 a with respect to the Hall element 113 a is different between the horizontally developed state and the vertically developed state of the display device 100. Further, as illustrated in FIG. 1C, in the folded state of the display device 100, the magnet 113b and the magnet 123a face each other with the hall element 113a interposed therebetween. That is, in each state of the display device 100, the positional relationship between the Hall element 113a, the magnet 113b, and the magnet 123a changes.

  Therefore, the Hall element 113a can output different signals depending on the direction of the magnetic flux and the change in magnetic flux density that are different for each state of the display device 100. 3 to 12, the Hall element 113a and the magnets 113b and 123a are not shown in order to simplify the description.

In this case, the operation of each panel is comprehensively controlled by a display control circuit provided on the one panel.

  In addition, the display device 100 according to the present embodiment is configured such that the first panel 101 and the second panel 102 perform communication between the panels by wireless communication, but is not limited thereto. For example, a communication cable or the like is provided inside each wire, which will be described later, which is a connecting means between the first panel 101 and the second panel 102, and the first panel 101 and the second panel are connected using the communication cable. It may be configured to perform communication with the panel 102.

  Hereinafter, the configuration of the first panel 101 and the second panel 102 of the present embodiment will be described in detail with reference to FIG. FIG. 3 is a three-view diagram illustrating the configuration of the first panel 101 and the second panel 102 of the display device 100 which is the first embodiment of the display device embodying the present invention.

  As shown in FIG. 3, the first panel 101 has a surface on which a groove 101c1 and a groove 101c2, which will be described later, are provided as a left side and a surface on the opposite side as a right side. And the 1st panel 101 makes the surface where the groove part 101b1 and the groove part 101b2 mentioned later are provided a lower side surface, and makes the surface of the opposite side the upper side surface.

  Note that the side (long side) on the lower surface side of the first panel 101 when viewed from the display unit 101a direction is the side 1 (first side), and the right side side (short side) of the first panel 101 is short. Let side 2 be side 2 (second side). As described above, the side 1 and the side 2 are orthogonal to each other.

  Further, as shown in FIG. 3, the second panel 102 has a surface on which a groove 102c1 and a groove 102c2 described later are provided as a right side and a surface on the opposite side as a left side. And the 2nd panel 102 makes the surface in which the groove part 102b1 and the groove part 102b2 mentioned later are provided a lower side surface, and makes the surface on the opposite side the upper side surface.

  Note that the side (long side) on the lower surface side of the second panel 102 when viewed from the direction of the display unit 102a is the side 3 (third side), and the side (short side) on the left side of the second panel 102 is short. Let side 4 be side 4 (fourth side). As described above, the side 3 and the side 4 are orthogonal to each other.

  The first panel 101 and the second panel 102 can be changed to a plurality of states by changing the relative arrangement of the panels. For example, when the display device 100 is in a horizontally developed state, the first panel 101 and the second panel 102 are in a state where the left side surface of the first panel 101 and the right side surface of the second panel 102 are in contact with each other. (Horizontal display state). In addition, when the display device 100 is in the vertically developed state, the first panel 101 and the second panel 102 are developed such that the lower surface of the first panel 101 and the upper surface of the second panel 102 are in contact with each other. State (vertical display state).

  That is, in the relative arrangement of the first panel 101 and the second panel 102, the state in which the side 3 of the second panel 102 is positioned on the extension line of the side 1 of the first panel 101 is the horizontal display state. It is. Further, a state in which the side 4 of the second panel 102 is positioned on an extension line with the side 2 of the first panel 101 is a vertical display state.

  As described above, in order to place the display device 100 in the horizontally developed state, the relative arrangement of the first panel 101 and the second panel 102 needs to be in the horizontally displayed state. In order to place the display device 100 in the vertically expanded state, the relative arrangement of the first panel 101 and the second panel 102 needs to be in the vertically displayed state.

  Next, in the relative arrangement of the first panel 101 and the second panel 102, the A surfaces of the first panel 101 and the second panel 102 face each other, and the B surfaces face each other in different directions.

That is, the state in which the first display portion 101a of the first panel 101 and the second display portion 102a of the second panel 102 face each other is the storage state.

  As the storage state, the relative arrangement of the first panel 101 and the second panel 102 can be changed to two states, a storage state A and a storage state B. The storage states A and B described above are different from each other on the first panel 101 and the second panel 102 in the groove portions through which each wire described later is guided. Details of this will be described later.

  In addition, among the relative arrangements of the first panel 101 and the second panel 102, the B surfaces of the first panel 101 and the second panel 102 face each other, and the A surfaces face each other in different directions. It is a double-sided state. That is, the state in which the first display unit 101a of the first panel 101 and the second display unit 102a of the second panel 102 are exposed and facing each other is a double-sided state.

  When the first panel 101 and the second panel 102 are housed and double-sided, the side 1 of the first panel 101 and the side of the second panel 102 are viewed from the direction (display direction) perpendicular to the A plane. The sides 3 overlap (match) each other. Further, when the first panel 101 and the second panel 102 are housed and double-sided, the side 2 and the second panel of the first panel 101 are viewed from the direction (display direction) orthogonal to the respective A planes. The sides 4 of 102 overlap (match) each other.

  Further, the state of the first panel 101 and the second panel 102 is changed while the relative arrangement of the first panel 101 and the second panel 102 is changed to each state described above. State.

  Note that the relative arrangement of the first panel 101 and the second panel 102 may not be changed to the above-described storage state depending on the state of the third panel 201 or the fourth panel 202. For example, in a state where the display unit 101a and the display unit 201a face each other, the state of the first panel 101 and the second panel 102 cannot be set to the storage state. Further, when the display unit 102a and the display unit 202a face each other, the state of the first panel 101 and the second panel 102 cannot be set to the storage state.

In the first panel 101, the length (horizontal width) of the side 1 is Wp, the length (vertical width) of the side 2 is Hp, and the length (horizontal width) of the side of the first display portion 101a parallel to the side 1 is set. When the length (vertical width) of the display portion 101a parallel to Wd and side 2 is Hd, the relationship of the following expression (1) is satisfied.
Wp> Hp, Wd> Hd (1)

That is, the length Wp in the longitudinal direction of the first panel 101 is larger than the length Hp in the lateral direction of the first display unit 101a. The length Wd in the longitudinal direction of the first panel 101 is larger than the length Hd in the longitudinal direction of the first display portion 101a. Further, the first panel 101 of the present embodiment satisfies the relationship of the following formula (2).
Wp: Hd = 3: 2 (2)

The above is the description of the second panel 102.

  Hereinafter, the details of the wires 103 to 106 that are connection means (first connection means) in the display device 100 of the present embodiment will be described. The wires 103 to 106 are linear connection means formed of synthetic fiber or a metal material, and connect the first panel 101 and the second panel 102 in a foldable manner.

  Each of the wires 103 to 106 has elasticity in the linear direction and flexibility in the bending direction. Moreover, the both ends of each wire are connection means in a shape in which the ends are not joined to each other. That is, the wires 103 to 106 of the present embodiment have a non-loop shape.

  The wires 103 to 106 described above are fixed to the fixing portions in a state where both ends are pulled so that tension is generated in the wire direction of the wires. For example, in the case of the wire 103, the wire 103 is fixed to the fixing portion 101e1 and the fixing portion 102f1 so that the wire 103 is not bent in each of the unfolded state and the folded state (stored state or double-sided state) of the display device 100. With this configuration, the wires 103 to 106 pass through paths that have the shortest lengths while being led into the corresponding groove portions.

  Note that the tension of each wire is adjusted in consideration of the third panel 201 and the fourth panel 202. Therefore, even when the display device 100 is in the folded state described above, the wires 103 to 106 that connect the first panel 101 and the second panel 102 do not bend.

  The wires 103 to 106 are subjected to external force applied when the user changes (expands or folds) the state of the display device 100. In order to prevent the wire from falling off the groove due to the external force, it is desirable to increase the tension of the wire and reduce the looseness. Specifically, in order to prevent the wire from being broken by the external force described above, it is desirable to reduce the tension of the wire to a predetermined value or less calculated from the tensile strength of the wire. That is, it is necessary to keep the tension of each wire within a desirable range in order to ensure reliability in consideration of dropping of the wire from the groove and breakage of the wire. However, the tension of each wire varies from the design value depending on the processing accuracy and assembly accuracy of the parts.

  Therefore, in the display device 100 of the present embodiment, a tension adjustment mechanism that can adjust the tension of each corresponding wire is provided in each fixing portion. Furthermore, each of the wires 103 to 106 according to the present embodiment is an independent member, and is fixed to different fixing portions.

  As the tension adjusting mechanism described above, for example, a hole portion into which each wire can be inserted is provided at each position of the first panel 101 and the second panel 102 corresponding to each fixing portion described above. And the fixing pin for fixing the edge part of a wire to a hole is inserted in the state where the wire was inserted in the said hole. If it is this structure, the tension | tensile_strength of a wire can be adjusted by changing the quantity of the wire inserted in a hole, and the insertion degree of a pin. In this case, each fixing portion corresponds to the tension adjusting mechanism described above.

  Note that the outer diameter of the fixing pin described above is set slightly larger than the inner diameter of the hole. In this state, the inside of the hole portion and the outside of the fixing pin slide with each other while generating a predetermined frictional force, so that the fixing pin can be prevented from falling out of the hole portion.

  With the configuration described above, the display device 100 of this embodiment can independently adjust the tension of each wire. Therefore, it can prevent that each wire falls out from the corresponding groove part, or is damaged.

  Even if the tension of the wire 103 is adjusted using the tension adjusting mechanism of the fixing portion 101e1, the tension of the other wires 104 to 106 does not change. Therefore, in the display device 100 of the present embodiment, only the tension of the wire that needs to be adjusted can be adjusted independently. The above is the description of the wires 103 to 106.

  In the present embodiment, the groove portions and the fixing portions of the first panel 101 and the second panel 102 are centered on the side 2 and the side 4 when the display device 100 is in a horizontally developed state. It is provided at a position having a line symmetry relationship. Further, the groove portions and the fixing portions of the first panel 101 and the second panel 102 have a line-symmetric relationship with the sides 1 and 3 as the center line when the display device 100 is in a vertically developed state. It is provided in the position.

  In the display device 100 according to the present embodiment, as a method of fixing each wire corresponding to each fixing portion, various methods such as adhesion, heat caulking, crimping, hooking, etc. can be used in addition to the above-described fixing pins. Can be adopted.

The above is the change in the relative arrangement of the panels accompanying the operation of changing the display device 100 from the folded state to the vertically expanded state.

  As described above, the display device 100 according to the present embodiment displays a plurality of different states such as a horizontally expanded state, a vertically expanded state, and a folded state by changing the relative arrangement of the plurality of panels. The state of the device 100 can be changed. That is, the display device 100 of the present embodiment can change the relative arrangement of the panels so that the sides positioned on the extension line are different between the panels.

  For example, if the state of the display device 100 is changed to the folded state, the size of the entire device can be reduced, and thus a display device with improved portability can be provided to the user.

  Further, if the state of the display device 100 is changed to the expanded state, a display device having an enlarged display area can be obtained by dividing a single image (original image) into a plurality of images and displaying them on each display unit. It can be provided to the user. That is, the display device 100 of the present embodiment can reduce the size of the device itself and the size of the display area depending on the state, so that the display area on the same plane can be expanded while improving portability. .

  Here, the shape of the display image is generally rectangular. Therefore, when a single image is divided into a plurality of parts and displayed on each display unit, if the outer shape of each display unit is rectangular, the display image is displayed as large as possible in the display area including each display unit. Can be made.

  On the other hand, when the shape of the outer shape combined with each display unit is a shape other than a rectangle such as an L shape, each display unit is compared with the case where the outer shape combined with each display unit is a rectangle. The size of the image that can be displayed in the display area combined with is reduced. That is, in a display device that can change the relative arrangement of a plurality of panels each provided with a display unit, when a single image is divided into a plurality of images and displayed on each display unit, the shape of the entire display region It is desirable to change the state of the display device so that becomes rectangular.

  As described above, the display device 100 of the present embodiment has a configuration in which each of a plurality of panels each having a display unit is connected by two different types of connecting means. Specifically, the display device 100 includes first hinges 203 and 204 that can change the relative arrangement of the panels around a single rotation axis, and each panel facing a plurality of directions that are orthogonal to each other. And wires 103 to 106 that can change the relative arrangement of each other.

  Then, the first panel 101 and the second panel 102 are connected by the wires 103 to 106 described above, the first panel 101 and the third panel 201 are connected by the first hinge 203, and the second hinge 204 is connected. The second panel 102 and the fourth panel 202 are connected to each other. In other words, the first panel 101 and the second panel 102 of the present embodiment are arranged in a state in which the display portions of the panels face in the same direction, and the relative arrangement of the panels is set so that the adjacent sides are different. Can be changed. In addition, the first panel 101 and the third panel 201, and the second panel 102 and the fourth panel 202 are in a state in which the display portions of the panels face each other in the same direction. The relative arrangement of the panels can be changed so that they are adjacent to each other.

  With this configuration, the relative arrangement of the first panel 101 and the second panel 102 can be changed to the horizontal display state and the vertical display state described above. Further, with the above-described configuration, the relative arrangement of the first panel 101 and the third panel 201 can be changed to a state in which the side 5 is positioned on the extension line of the side 1. Further, with the above-described configuration, the relative arrangement of the second panel 102 and the fourth panel 202 can be changed to a state in which the side 7 is located on the extension line of the side 3.

  Furthermore, with the above-described configuration, the display device 100 according to the present embodiment allows each panel to have a rectangular shape with the outer shape of each display unit being always in a state where the display units face the same direction. The relative arrangement can be changed. Therefore, the display device 100 according to the present embodiment can display a display image as large as possible in a display area including the display units when a single image is divided into a plurality of images and displayed on the display units.

  Here, a display image display method according to the state of the display device 100 will be described with reference to FIG. The signal output from the Hall element 113a when the display device 100 is in the horizontally expanded state is the signal A, the signal output when the display device 100 is in the vertically expanded state is the signal B, and is output when the display device 100 is in the folded state. Let the signal be signal C.

In the flowchart of FIG. 12, it is assumed that the display device 100 is set in advance so that a single original image can be divided into a plurality of images and displayed on each display unit of the display device 100.

  When the display control process is started in response to the power supply of the display device 100 being turned on or the state of the display device 100 being changed, in step S1201, the first display control circuit 110 displays the Hall element. The signal output from 113a is received. The signal is information regarding the magnetic force (the direction of the magnetic flux, the magnitude of the magnetic flux density, etc.) of the magnet 113b and the magnet 123a detected by the Hall element 113a.

  In step S1202, the first display control circuit 110 determines whether or not the magnitude of the signal received in step S1201 is greater than or equal to a predetermined signal (threshold signal). The threshold signal described above may be set to any value as long as it is at least smaller than the signals A to C described above.

  When the first display control circuit 110 determines that the received signal is smaller than the threshold signal (NO in step S1202), the first display control circuit 110 stops the display by each display unit in step S1206. .

  If the first display control circuit 110 determines that the received signal is equal to or greater than the threshold signal (YES in step S1202), the first display control circuit 110 received from the hall element 113a in step S1203. Determine the type of signal.

  If the first display control circuit 110 determines that the received signal is the signal A, in step S1204, the first display control circuit 110 displays a display image corresponding to the laterally developed state of the display device 100. It is displayed on each display unit of the apparatus 100 (hereinafter referred to as horizontal display). The horizontal display of the display image refers to the size of the display image displayed on each display unit so that the original image can be displayed in the maximum in the display area where the display units are combined in the horizontal development state of the display device 100. This is the state to be set and displayed.

  When the first display control circuit 110 determines that the received signal is the signal B, in step S1205, the first display control circuit 110 displays a display image corresponding to the vertically developed state of the display device 100. The information is displayed on each display unit of the apparatus 100 (hereinafter referred to as vertical display). The vertical display of the display image refers to the size of the display image displayed on each display unit so that the original image can be displayed in the largest size in the display area where the display units are combined in the vertically expanded state of the display device 100. This is the state to be set and displayed.

  When the first display control circuit 110 determines that the received signal is the signal C, in step S1206, the first display control circuit 110 stops the display by each display unit. Note that the processing in step S1206 described above may not be configured to end display of the display image on each display unit, but may be configured to display the entire original image on each display unit.

  The first display control circuit 110 ends the current display control process after the above-described steps S1204 to S1206 are completed. The display control process described above may be configured to start a new process every time the state of the display device 100 is changed. Specifically, in response to a change in the value of the signal output from the Hall element 113a, the first display control circuit 110 executes display control processing based on the value of the newly detected signal. The above is the display control process of this embodiment.

  As described above, the display device 100 according to the present embodiment displays the largest display image in the entire display area in accordance with the state of the display device 100 when a single image is divided and displayed. be able to.

By changing, it is possible to view a display image corresponding to the size of the display image.

  For example, when the ratio of two orthogonal sides (for example, the long side and the short side) of the original image is a ratio frequently used for a photograph (or an image sensor) such as 3: 2 or 16: 9, the display device 100 is used. The state of is changed to a vertically expanded state. In addition, when the ratio of two orthogonal sides of the original image is a horizontally long ratio (for example, a ratio of 2: 1 or more) such as a scope size frequently used for movies or a so-called panoramic image, the display device 100. The state of is changed to the horizontally expanded state.

  As described above, the display device 100 according to the present embodiment changes the relative arrangement of the panels according to the ratio (aspect ratio) of the two sides of the original image that are orthogonal to each other by the user. It can be displayed as large as possible.

  Here, in the present embodiment, the wires 103 to 106 are employed as the connecting means for connecting the first panel 101 and the second panel 102.
