  Conventionally, this type of electro-optical device functions as a so-called flat panel display by winding up and storing the display portion in a roll shape when not in use and positioning the display portion extended in use in a planar shape ( For example, see Patent Documents 1 and 2.) In this case, the display unit has flexibility, and in the extended state, the display unit is in a free state except for one side on the end side in the extending direction (that is, the roll body side).

JP-A-11-95692 (FIGS. 1 and 2) Japanese Unexamined Patent Publication No. 2000-132122 (FIG. 1)

  In such a conventional electro-optical device, the flexible display unit is easy to sag due to its own weight in the extended state. For this reason, it is necessary for the user to support the display unit by hand during use, or to support the display unit with a plate-like member separately prepared as an accessory so as not to impair the flatness of the display unit. Was cumbersome. That is, the former treatment reduces the workability of other devices, and the latter treatment reduces the portability of the electro-optical device itself.

  An object of the present invention is to provide an electro-optical device having good handling and an electronic apparatus including the same, which can appropriately maintain the flatness of the drawn-out display unit with a simple structure. .

The electro-optical device of the reference example includes a sheet-like display unit configured to be capable of being fed and wound, and a supporting unit that supports two sides along the feeding direction of the fed-out display unit. Along with the feeding operation and winding operation of the display unit, the display unit expands and contracts in the feeding direction.

According to this configuration, when the display unit is extended, the support means is extended along with the display unit to support the two sides along the supply direction of the display unit. Usually, since the display unit is supported for winding on the one end side in the feeding direction, the fed display unit can be supported on at least three sides including the one side. Thereby, the sag of the extended display unit can be suitably prevented structurally, and the flatness can be appropriately maintained. This configuration is particularly useful when the longitudinal direction of the display unit coincides with the feeding direction.
Further, since the support means contracts with the winding operation of the display unit, when the display unit is wound up, the support unit itself does not have to occupy a large device space. Thereby, the electro-optical device itself can be made compact as a whole. Furthermore, since the support means is configured to expand and contract in accordance with the feeding operation and the winding operation of the display unit, it is not necessary for the user to separately prepare a support member, and the handling property of the electro-optical device itself can be suitably improved. it can.
Note that “support” by the support means includes not only supporting the side of the display unit from the lower side, for example, but also supporting it by sandwiching it, and extending the side of the display unit. Not only supporting in the direction but also supporting in part is included.

  The electro-optical device refers to a general display device including an electro-optical element that emits light by an electrical action or an electro-optical element that changes the state of light from the outside. For example, a liquid crystal display device, an organic EL display device, Examples include an electron emission device, a PDP device, and an electrophoretic display device.

  In this case, the support means includes a pair of link mechanisms provided corresponding to the two sides along the feeding direction of the display unit, and each link mechanism has a plurality of links connected to each other so as to be stretchable. In addition, it is preferable that the plurality of links be configured to be able to support one side along the feeding direction of the display unit.

  According to this structure, a support means can be comprised with the link mechanism in which a structure becomes easy easily, and the one side of a display part can be supported with the some link which comprises each link mechanism.

  In this case, each link mechanism includes two links, and the two links are configured to be positioned substantially parallel to one side along the feeding direction of the display unit in accordance with the feeding operation of the display unit. In connection with the winding operation, it is preferable that the connecting portions of both the links are foldable to be mutually foldable inside the display portion.

  According to this configuration, when the display unit is extended, the two links are positioned in a substantially straight line, and one side along the extending direction of the display unit is supported. On the contrary, when the display unit is wound, the two links are bent so as to be folded inside each other with the connecting portion serving as a fulcrum without protruding outside the display unit. Thereby, the handleability of the electro-optical device when the display unit is wound can be improved from the viewpoint of space.

  In this case, each link mechanism has a connecting pin for connecting two links and two fixing pins provided on the base side of the two links, and the connecting pins are displayed with respect to a straight line connecting the two fixing pins. It is preferable that the offset is always arranged inside the portion.

  According to this configuration, with the winding operation of the display unit, a component force is applied to the two links in the direction in which the two links are folded inside the display unit at the connecting pins. Thereby, on structure, it becomes possible to fold two links appropriately inside a display part.

  Similarly, it is preferable that each link mechanism is composed of an elastic link in which a plurality of links are crossed and connected.

  According to this configuration, it is possible to dispersely and partially support one side along the extending direction of the display unit in the extending direction by adopting an extendable link, that is, a pantograph, as the link mechanism.

  Similarly, the support means includes a parallel link mechanism, and the parallel link mechanism is configured to be able to support one side along the extending direction of the display unit, and is connected to each other via the first connection pins. And two second links that are configured to be able to support the other side of the display unit in the extending direction and are connected to each other via the second connecting pins, and the first connecting pin and the first link in the direction orthogonal to the extending direction. The two first links and the two second links are arranged in parallel with each other, and in the feeding direction in accordance with the feeding operation and the winding operation of the display unit. It is preferable to expand and contract in parallel with each other.

  According to this configuration, when the display unit is extended, each of the first and second two links supports two sides along the display unit extension direction, and the support means is configured by a parallel link mechanism as described above. Therefore, the support means can be appropriately expanded and contracted, and accordingly, the display unit can be appropriately extended and wound. That is, the skew of the display unit can be suitably prevented during the feeding operation and winding operation of the display unit.

  Similarly, the support means includes a pair of support units provided corresponding to two sides along the feeding direction of the display unit, and each support unit is telescopically nested with the display unit feeding operation and winding operation. It is preferable to have a plurality of support members connected by a formula, and the plurality of support members are configured to be able to support one side along the feeding direction of the display unit.

  According to this configuration, when the display unit is extended, the plurality of support members extend from the inner side or the outer side in order to advance to the outside in order to support one side along the extension direction of the display unit. On the other hand, when the display unit is wound up, the plurality of support members are shrunk so as to be concealed inside from the inside or the outside. In this way, by configuring the support means with a simple nested structure, it is possible to appropriately support two sides along the feeding direction of the display unit, and to suitably improve the handleability of the electro-optical device itself. Can do.

Electro-optical device of the present invention, the feeding and windable configured sheet-like display unit, provided in the two sides along the feeding direction of the display unit, up feeding and winding capable formed integrally with the display unit comprising a pair of support-like sheet, and each support, in a state where the display unit is fed all those which are configured to be bent in the normal direction of the display unit.

  According to this configuration, when the display unit is extended, the pair of supports are extended integrally with the display unit, but the display unit is bent in the normal direction of the display unit while the display unit is extended. The rigidity in the slack direction can be increased with respect to the two sides along the feeding direction. Thereby, since the display part extended | stretched can support at least 3 sides in total including the one side of the termination | terminus side of the supply direction supported for winding, a slack is suppressed suitably and the planarity is structurally Maintained properly. Moreover, when each support body is bent in the original state and the display portion is wound, each support body is also wound integrally therewith. For this reason, in the state which wound up the display part, an apparatus space does not need to be occupied widely by each support body. That is, similar to the above, the electro-optical device itself can be made compact and easy to handle.

  In this case, it is preferable that each support has the same degree of flexibility and the same thickness as the display unit.

  According to this structure, since the property regarding the flexibility etc. of a support body is substantially the same as a display part, the integrity of a display part and a support body can be improved. Thereby, the feeding operation and the winding operation of the display unit and the support can be performed smoothly and stably.

  An electronic apparatus according to the present invention includes the above-described electro-optical device according to the present invention.

  According to this configuration, it is possible to provide an electronic apparatus equipped with an electro-optical device that is well handled. In addition, as an electronic device, various electric products etc. correspond to this other than a mobile telephone, a personal computer, for example.

According to the electro-optical device of the present invention, since the two sides along the drawing direction of the drawn-out display unit can be supported by a simple structure, the flatness of the drawn-out display unit can be appropriately maintained and displayed. The visibility of the part can be improved, and in particular, the handling properties such as workability and portability can be improved.

According to the electronic apparatus of the present invention, since the electro-optical device is provided, it is possible to provide an electronic apparatus that is excellent in visibility and handling of the display unit.

  Hereinafter, an electro-optical device and an electronic apparatus including the same according to preferred embodiments of the present invention will be described with reference to the accompanying drawings. This electro-optical device is a display device that uses a display unit housed in a roll shape, and can keep the flatness of the display unit in a structurally appropriate state when the display unit is extended. .

  As shown in FIGS. 1 and 2, an electro-optical device 1 includes a sheet-like display unit 2, a roll 3 that winds the display unit 2 so that the display unit 2 can be unwound and wound, and a storage case that stores the roll 3 therein. 4, a gripping case 5 provided at the feeding end of the display unit 2, and support means 6 for supporting two sides 11 and 11 along the feeding direction of the fed display unit 2.

  The display unit 2 includes a substrate made of, for example, plastic, has a predetermined thickness as a whole, and has flexibility. The display unit 2 functions as a display area on the surface (upper surface) side for displaying various information. As the display method of the display unit 2, various methods can be used. That is, as the electro-optical device 1, a liquid crystal display device, an organic EL display device, an electron emission device, a PDP device, an electrophoretic display device, or the like can be used.

  The display unit 2 is fixed to the roll 3 with its end portion in the feeding direction extending in the extending direction (a direction perpendicular to the feeding direction). Moreover, the display part 2 is being fixed to the holding | grip case 5 over the extending direction in the start end part (feeding end) of the feeding direction.

  The gripping case 5 is formed in a box shape, and includes a driving unit 21 having a driver for driving the display unit 2 and a control unit 22 that controls the entire electro-optical device 1 including the driving unit 21. And are built in. A part of the support means 6 is fixed inside the gripping case 5, and a first storage port 25 for storing a later-described link mechanism 40 of the support means 6 is provided on the side surface 24 on the storage case 4 side. It is formed in a slit shape.

  The storage case 4 has a box shape with a dome-shaped top surface, is formed slightly larger than the gripping case 5, and holds the roll 3 rotatably therein. Similarly to the gripping case 5, the storage case 4 fixes a part of the support means 6 inside thereof, and stores a later-described link mechanism 40 of the support means 6 on the side surface 32 on the gripping case 5 side. The second storage port 31 is formed in a slit shape. The second storage port 31 also serves as a feed-out port for feeding the display unit 2 wound around the roll 3 out of the storage case 4.

  When the electro-optical device 1 is not used, the display unit 2 is wound around the roll 3 and stored in the storage case 4 (see FIG. 5). At this time, the support means 6 is stored in the storage case 4 and the gripping case 5 via the first storage port 25 and the second storage port 31, and the electro-optical device 1 has the side surface 32 of the storage case 4 of the gripping case 5. It will be in the state contact | abutted to the side surface 24. FIG. That is, when the electro-optical device 1 is not used, the electro-optical device 1 is downsized to a size that combines the storage case 4 and the holding case 5.

  On the other hand, when using the electro-optical device 1, the gripping case 5 is pulled away from the storage case 4. Then, the display unit 2 is drawn out of the storage case 4 from the roll 3, and the display area is exposed to be visible to the outside. When the feeding operation of the display unit 2 is completed, the electro-optical device 1 is ready for use. At this time, the four sides of the display unit 2 are fixed or supported by the roll 3, the gripping case 5, and the support means 6. Thus, the flatness of the display unit 2 is appropriately maintained (described later).

  The feeding operation of the display unit 2 can be performed manually, but may be automated using an actuator such as a motor. The winding operation of the display unit 2 can be similarly automated. For example, the winding operation of the display unit 2 can be performed by incorporating, for example, a spring that constantly urges the roll 3 in the winding direction of the display unit 2 into the storage case 4. May be executed. In this case, however, the storage case 4 is provided with a lock mechanism that maintains the state of the display unit 2 that has been extended. Needless to say, the storage case 4 and the holding case 5 may be of any size, and of course, the control unit 22 or the like may be incorporated on the storage case 4 side.

  Next, the support means 6 will be described in detail with reference to FIGS. The support means 6 includes a pair of link mechanisms 40 and 40 corresponding to the two sides 11 and 11 along the feeding direction of the display unit 2, and each link mechanism 40 is accompanied by a feeding operation and a winding operation of the display unit 2. The display unit 2 is configured to be extendable and contractible as a whole in the feeding direction.

  Each link mechanism 40 is provided on two links 41 and 42 having a substantially oval shape in plan view, a connecting pin 43 that connects both links 41 and 42, and a base side of the link 41, and the link 41 is attached to the storage case 4. A fixing pin 44 to be fixed and a fixing pin 45 provided on the base side of the link 42 and fixing the link 42 to the gripping case 5 are provided. The connecting pin 43, the fixing pin 44, and the fixing pin 45 constitute a turning pair of each link mechanism 40.

  The link 41 and the link 42 have the same length and shape, and expand and contract as a whole with the feeding operation and the winding operation of the display unit 2. That is, the two links 41 and 42 are positioned in parallel to and directly below the side 11 along the feeding direction of the display unit 2 in accordance with the feeding operation of the display unit 2, and the one side 11 of the display unit 2 is placed on the lower side ( Support from the back side.

  In this embodiment, as shown in FIGS. 1 and 3, the outer end surfaces of the two links 41 and 42 aligned in a straight line are the end surfaces of the side 11 along the extending direction of the display unit 2 that has been extended. It is located almost directly below. Of the links 41 and 42, the link 41 located on the upper side actively supports the side 11 of the display unit 2. Instead of this configuration, the end face of the side 11 along the feeding direction of the display unit 2 that has been fed out may be configured to face directly above the axial line of the two links 41 and 42 aligned in a straight line. Good.

  On the other hand, as shown in FIG. 4, with the winding operation of the display unit 2, the link 41 and the link 42 are mutually folded to the inside of the display unit 2 with the connecting pin 43 as a fulcrum. In this case, the base side of the link 41 is configured to be able to contact the opening edge of the second storage port 31 so that the links 41 and 42 are bent inwardly of the display unit 2, and the link 42. It is preferable that the base side is configured to be able to contact the opening edge of the first storage port 25.

  Then, at the final stage when the winding operation is completed, as shown in FIG. 5, each link mechanism 40 is housed across the housing case 4 and the gripping case 5 around the connecting pin 43. The link 41 is stored in the storage case 4 mainly through the second storage port 31, and the link 42 is stored in the gripping case 5 mainly through the first storage port 25.

  As described above, according to the present embodiment, in the use state of the electro-optical device 1 in which the display unit 2 is extended, the opposite sides 11 and 11 along the extending direction of the display unit 2 are connected to the pair of link mechanisms 40 and 40. Partially supported. In this state, the remaining opposite sides of the display unit 2 are fixed to the storage case 4 and the holding case 5, respectively. Accordingly, the four sides of the extended display portion 2 can be supported in a frame shape including fixation, and thus the flatness of the extended display portion 2 can be appropriately maintained in structure.

  Further, when the electro-optical device 1 is wound around the display unit 2, the display unit 2 is stored in a roll shape in the storage case 4, and each link mechanism 40 protrudes outside the display unit 2. Instead, it is stored between the storage case 4 and the gripping case 5. Thereby, the handleability of the electro-optical device 1 in the unused state can be enhanced from the viewpoint of space. Although the number of links constituting each link mechanism 40 has been described as two, it is of course not limited to this, and may be two or more.

  Next, with reference to FIG. 6, the support means 6 according to the second embodiment of the present invention will be described focusing on the differences from the first embodiment. In the present embodiment, the two links 41 and 42 are more suitably folded inside the display unit 2 during the winding operation of the display unit 2. Specifically, as shown in FIG. 6, the connecting position of the two links 41 and 42 by the connecting pin 43 is slightly eccentric to the inside of the display unit 2 with respect to the first embodiment.

  That is, the connecting pin 43 is always offset and arranged inside the display unit 2 with respect to the straight line connecting the two fixing pins 44 and 45. As a result, the two links 41 and 42 are positioned substantially in parallel and directly below the one side 11 of the display unit 2 that has been extended, and at the position of the connecting pin 43 during the winding operation. A component force is applied in the direction of folding inward. Therefore, even if there is no relationship between the link 41 and the second storage port 31, it is useful.

  As shown in FIG. 7, the support means 6 according to the third embodiment is constituted by a parallel link mechanism. In addition to the pair of link mechanisms 40, 40 in each of the embodiments described above, the parallel link mechanism is a moving plate 51 in which the connection pins 43, 43 (first connection pin and second connection pin) of the pair of link mechanisms 40, 40 are fixed. Is further provided.

  The moving plate 51 is provided between the storage case 4 and the gripping case 5 and arranges a pair of link mechanisms 40 and 40 in parallel. The storage case 4 and the holding case 5 have outer shapes corresponding to the moving plate 51. That is, in a state where the display unit 2 is wound up, both are configured in a mutually complementary shape so that the moving plate can be accommodated between the storage case 4 and the gripping case 5 without a substantial gap.

  According to the present embodiment, the link 41 and the link 42 (two first links) of the one link mechanism 40 and the link 41 and the link of the other link mechanism 40 in accordance with the feeding operation and the winding operation of the display unit 2. 42 (two second links) extend and contract in parallel with each other. Thereby, the expansion / contraction of the support means 6 in the pay-out direction can be performed as a whole.

  In addition, since the fixing pins 44 and 45 of each link mechanism 40 are fixed to the storage case 4 and the gripping case 5, respectively, when the display unit 2 is extended to separate the gripping case 5 from the storage case 4, The display unit 2 can be properly fed out without being skewed, and the roll 3 can be moved without skewing the display unit 2 even during the winding operation of the display unit 2 to bring the gripping case 5 close to the storage case 4. Can be wound properly. Furthermore, it becomes possible to support the center part of the display part 2 extended | stretched from a lower side with a moving plate.

  As shown in FIG. 8, the pair of link mechanisms 40, 40 of the support means 6 according to the fourth embodiment are each configured by an elastic link that crosses a plurality of links 61 and is connected by a plurality of connecting pins 62. . Each telescopic link 40 is a pantograph, and slide pins 63 and 63 are provided at the bases of the two links 61 and 61 on the storage case 4 side, and the bases of the two links 61 and 61 on the gripping case 5 side. Are provided with slide pins 64, 64, respectively.

  The storage case 4 is provided with slide grooves 71, 71 for guiding the slide pins 63, 63 in a direction orthogonal to the expansion / contraction direction, corresponding to the pair of expansion / contraction links 40, 40. Similarly, the holding case 5 is provided with slide grooves 73 and 74 for guiding the slide pins 64 and 64, respectively. Therefore, the plurality of links 61 of each of the telescopic links 40 can support the side 11 along the extending direction of the extended display unit 2 in a dispersive and partial manner over the extending direction.

  Next, the support means 6 according to the fifth embodiment will be described with reference to FIG. In the present embodiment, a mobile phone will be described as an example of an electronic device on which the electro-optical device 1 is mounted. As shown in the figure, in the cellular phone 100, the storage case 4 of the electro-optical device 1 is built in a main body 102 in which a plurality of numeric keys 101 are distributed. The gripping case 5 of the electro-optical device 1 is provided so as to be able to be drawn out and stored with respect to the main body 102.

  The support means 6 has a different structure from the above embodiments. That is, the support means 6 includes a pair of support units 111 and 111 corresponding to two sides along the feeding direction of the display unit 2, and each support unit 111 is fed out along with the feeding operation and the winding operation of the display unit 2. A plurality of support members 112 are connected in a telescopic manner so as to expand and contract in the direction.

  The plurality of support members 112 are configured to be smaller in size from the main body 102 side toward the gripping case 5 side. Each support member 112 is formed, for example, in a “U” shape in cross section, and is configured to be able to sandwich one side 11 along the feeding direction of the display unit 2. Among the plurality of support members 112, the support member 112 having the largest size is fixed to the main body 102, and the support member 112 having the smallest size is fixed to the gripping case 5.

  According to the present embodiment, as each display unit 2 is extended, the other support members 112 are pulled out from the support members 112 having a large size in each support unit 111, and finally the display units 2 are displayed by the plurality of support members 112. The one side 11 along the feeding direction is supported. Therefore, as in the above embodiment, the flatness of the extended display unit 2 can be maintained appropriately, and a large display area can be secured for the mobile phone 100.

  Further, with the winding operation of the display unit 2, each support unit 111 is housed so that the other support member 112 is concealed by the support member 112 having a large size. Therefore, the display unit 2 having a large display area can be stored in the main body unit 102 when the mobile phone 100 is talking or waiting, and management of storage / transportation of the mobile phone 100 is facilitated. .

  This embodiment is a modification of the fifth embodiment. As shown in FIG. 10, the electro-optical device 1 can be appropriately attached to the main body 102 of the mobile phone 100. In this case, for example, the connector part 121 provided in the main body part 102 of the mobile phone 100 and the connector part 122 provided in the electro-optical device 1 are connected by a cable 123 or the like, and the side surface of the main body part 102 is connected to the electro-optical device 1. The storage case 4 is incorporated. According to this embodiment, the versatility of the electro-optical device 1 can be improved. In addition, FIG. 10 has shown the state which extended the display part 2. As shown in FIG.

  Next, a seventh embodiment of the present invention will be described with reference to FIG. 11 focusing on differences from the first embodiment. FIG. 11 is a diagram schematically showing the electro-optical device 1 of this embodiment in a simplified manner as compared with the first embodiment. As shown in the figure, the electro-optical device 1 includes a pair of supports 131 and 131 configured to be able to be fed and wound integrally with the display unit 2 instead of the support means 6 of the first embodiment. Yes.

  Each support 131 has the same degree of flexibility and the same thickness as the display unit 2. Each support 131 has a predetermined width in a direction orthogonal to the feeding direction of the display unit 2, and is provided on one side 11 along the feeding direction of the display unit 2. Both ends in the longitudinal direction of each support 131 are in a free state, one end faces the roll 3 with a predetermined gap, and the other end contacts the side surface 24 of the gripping case 5 with a predetermined There is a gap. Each support 131 is configured to be bendable in the normal direction of the display unit 2 when the display unit 2 is extended.

  Therefore, when the display unit 2 is wound on the roll 3, each support body 131 is positioned in the same plane as the display unit 2. Thereby, each support body 131 can be wound around the roll 3 integrally with the display section 2, and the display section 2 and each support body 131 can be stored in the storage case 4. On the other hand, when the display unit 2 is unwound from this state, each support 131 is unwound from the roll 3 integrally with the display unit 2. In a state where the display unit 2 is completely extended, each support 131 can be bent in the normal direction of the display unit 2. In this state, when the pair of supports 131, 131 are bent so as to hang down from two sides along the feeding direction of the display unit 2, both ends of each support 131 are side surfaces 32 of the storage case 4 and the gripping case 5. , 24 so that they are sandwiched between them.

  Thereby, about two sides along the extended direction of the display part 2 extended, the downward slack can be suppressed and it becomes possible to maintain the flatness of the display part 2 structurally appropriately. As described above in the first embodiment, when the winding operation of the display unit 2 is performed by a spring, a lock mechanism is provided, but the pair of supports 131 and 131 also function as a part of the lock mechanism. be able to.
