[0010] Hereinafter, the embodiments will be specifically described with reference to the drawings.

[0011] The embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection configurations, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components not described in the independent claims are described as optional components.

[0012] Furthermore, each drawing is a schematic diagram and is not necessarily an exact illustration. In addition, in each drawing, substantially the same components are denoted by the same reference numerals, and duplicated explanations may be omitted or simplified.

[0013] Furthermore, in this specification, terms indicating the relationship between elements, such as parallelism, terms indicating the shape of elements, such as rectangle, and numerical ranges are not expressions that only express a strict meaning, but are expressions that also include a substantially equivalent range, for example, a difference of about a few percent.

[0014] In addition, in the drawings showing the display, the x-axis, y-axis, and z-axis represent the three axes of a three-dimensional Cartesian coordinate system. The z-axis is a direction parallel to the thickness direction of the display panel of the display. Furthermore, the surface on the positive side in the z-axis direction is referred to as the "top surface," the surface on the negative side in the z-axis direction is referred to as the "bottom surface," and the surface parallel to the z-axis is referred to as the "side surface." However, these correspondences indicate relative positional relationships and do not limit the orientation of the display according to the present disclosure during manufacture or use.

[0015] In the following description, unless otherwise specified, the "front surface" of a component in an information display device is the surface on which ambient light or external light is incident, and is the surface closer to the user viewing the information display device (i.e., the surface facing the same direction as the display surface of the display panel). Also, the "rear surface" of a component in an information display device is the surface opposite the "front surface" that faces away from the "front surface."

[0016] (Embodiment) A display according to an embodiment and an information display device including the display will be described below.

[0017] [composition] Fig. 1 is a schematic diagram for explaining an overview of an information display device according to the present embodiment. In Fig. 1, the outlines of a display 100 installed in a wall 20 and a display panel 121 of the display 100 are shown by dashed lines.

[0018] As shown in FIG. 1 , an information display device 10 according to this embodiment is disposed on a wall 20 and includes a surface member 30 and a display 100. The wall 20 is part of the interior of a moving object, such as a wall separating seats. The moving object is, for example, an airplane, but is not particularly limited as long as it is a vehicle capable of carrying people. The moving object may be a vehicle, a ship, or the like. The vehicle may be, for example, an automobile or a railway vehicle. The location where the information display device 10 is disposed is not limited to the wall 20, but may also be a seat, ceiling, floor, shelf, desk, or the like.

[0019] The information display device 10 displays information on the surface member 30 to provide the information to a user. The user is, for example, a passenger on a vehicle, such as a crew member. The information is, for example, content information, text information, images, and videos. In the information display device 10, light from the display panel 121 of the display 100 coming from the back side of the surface member 30 passes through the surface member 30, and the information is displayed on the surface member 30. The information display device 10 may display an operation screen on the surface member 30. In this case, the user can operate the operation screen displayed on the surface member 30 to change the information display and make requests to the crew, etc.

[0020] When the information display device 10 is powered on, the display panel 121 lights up and displays information on the surface of the surface member 30. At this time, only the information displayed on the display panel 121 is visible to the user through the surface member 30. On the other hand, when the information display device 10 is powered off, the display panel 121 turns off. At this time, the display 100 is almost invisible to the user through the surface member 30, that is, it is in an invisible state. Furthermore, even when the information display device 10 is powered on and the display panel 121 is lit, the portion of the display panel 121 on which no information is displayed (background color portion) is almost invisible to the user through the surface member 30, that is, it is in an invisible state.

[0021] When the information display device 10 is used inside an aircraft, examples of information and operations presented to a user (e.g., a passenger or a crew member) include transfer information, seat lighting control, audio control, Do not Disturb setting, entertainment device control, seat reclining, attendant call and its cancellation, weather information, information such as flight time and local time, presentation of seat number, display of lavatory availability, seat belt sign, door mode status display, etc. The information display device 10 may also have a function of lighting up the display panel 121 only when a user approaches using a touch panel or a motion sensor, etc.

[0022] The surface member 30 is a member arranged on the surface of the wall 20, and is at least a part of the member that constitutes the surface of the wall 20. There may be a boundary between the surface member 30 and the part of the surface of the wall 20 other than the surface member 30. The surface member 30 has a curved surface. The surface member 30 is larger than the display panel 121 (the display surface of the display panel 121). In other words, the display panel 121 is covered by the surface member 30, which has a surface area larger than the surface area of ​​the display panel 121. As a result, the edge of the surface member 30 is not positioned in a position that overlaps with the display panel 121, making the presence of the display 100 less noticeable to the user. The surface member 30 may be larger than the display 100.

[0023] The information display device 10 can be installed in a structure arranged inside a wall 20. FIG. 2 is a schematic perspective view for explaining installation of the information display device according to this embodiment in a structure. As shown in FIG. 2, the information display device 10 is installed in the structure 40 by fixing the display 100 so that it is sandwiched between the surface member 30 and the structure 40. The display 100 has a fixed portion 110 fixed to the structure 40, and a variable display portion 120 a portion of which is fixed to the fixed portion 110. The variable display portion 120 is a portion that has the above-mentioned display panel 121, and displays information via the surface member 30. The variable display portion 120 is also deformable in shape.

[0024] 3A, 3B, and 3C are schematic side views showing an example of a state in which an information display device according to the present embodiment is installed on a structure. When the information display device 10 is installed on the structure 40, the fixed unit 110 is fixed to the structure 40. Furthermore, the surface member 30 is installed on the structure 40, so that the variable display unit 120 is disposed between the surface member 30 and the structure 40, and is disposed in a shape that follows the curved shape of the surface member 30. Specifically, the variable display unit 120 is deformed into a shape that follows the shape of the surface member 30 due to the force that presses the variable display unit 120 with the surface member 30, and is disposed in a shape that follows the shape of the surface member 30. On the other hand, the fixed unit 110 has higher rigidity than the variable display unit 120, and is not deformed by the force that presses the variable display unit 120 with the surface member 30. Furthermore, the surface member 30 is disposed on the surface 128 side of the variable display unit 120, and the structure 40 is disposed on the back surface 129 side of the variable display unit 120.

[0025] The surface member 30 can be installed on the structure 40, and is detachably fixed to the structure 40 with, for example, bolts, pins, hook-and-loop fasteners, or the like. When the surface member 30 is installed on the structure 40, a force is generated in the surface member 30 that presses the variable display unit 120.

[0026] The surface member 30 is a plate-like or film-like member and has a curved surface 39. The thickness of the surface member 30 is, for example, constant. The curved shape of the surface 39 is not limited to the convex curved shape shown in Fig. 3A, but may also be a concave curved shape as shown in Fig. 3B or a wavy curved shape as shown in Fig. 3C, and is not particularly limited.

[0027] The surface member 30 is a member having a surface that is the same as or similar to the member that constitutes the surface of the wall 20. Light from the variable display unit 120 is incident on a rear surface 38 of the surface member 30, and information is displayed on a front surface 39 of the surface member 30. In other words, the rear surface 38 of the surface member 30 is the surface on the variable display unit 120 side, and is the surface onto which light from the variable display unit 120 is incident. The front surface 39 of the surface member 30 is the surface opposite the variable display unit 120 side, and is the surface that is viewed by the user.

[0028] The back surface 38 of the surface member 30 is in close contact with at least the area (area corresponding to the display surface of the display panel 121) on the surface 128 of the variable display unit 120 where information is displayed. In this case, a cushioning material (not shown) may be placed on the back surface 129 of the variable display unit 120, and the surface 128 of the variable display unit 120 may be pressed against the back surface 38 of the surface member 30 by the repulsive force of the cushioning material.

[0029] Furthermore, the variable display unit 120 is not adhered to the surface member 30. In other words, there is no adhesive force between the variable display unit 120 and the surface member 30 due to adhesive or the like, and the variable display unit 120 and the surface member 30 can be separated without damaging the variable display unit 120 or the surface member 30. This makes maintenance easy, and for example, when the display 100 breaks down, the display 100 can be easily repaired or replaced.

[0030] The surface member 30 has a predetermined light transmittance. By embedding the display 100 in the wall 20 (see FIG. 1 ) and covering it with the surface member 30, information can be displayed on the wall 20 without the user being aware of the presence of the display 100. The light transmittance of the surface member 30 is, for example, 8% to 15%. By configuring the surface member 30 to have such a light transmittance, light passing from the front surface 39 to the back surface 38 of the surface member 30 is suppressed, making the display 100 itself invisible from the outside, while allowing the display on the display 100 to be sufficiently visible even through the surface member 30. In other words, when the variable display unit 120 is lit, only the information displayed on the variable display unit 120 of the display 100 can be seen through the surface member 30. Furthermore, the surface member 30 may be configured so that some parts are light-transmitting and other parts are opaque, allowing only necessary parts to be displayed. For example, by providing a light-transmitting portion in a specific symbol shape, symbols can be displayed more clearly.

[0031] The variable display unit 120 (specifically, the display panel 121) has a screen brightness of 50 cd / m when lit, for example, after light is transmitted through the surface member 30. 2 More than 200cd / m 2 As a result, the display 100 itself is not visible from the front side of the surface member 30, while the display by the variable display unit 120 is sufficiently visible even through the surface member 30, and the display is not too dazzling to the user.

[0032] In order to make the display 100 invisible from the surface 39 side of the surface member 30, the light transmittance of the surface member 30 is, for example, about 10% (specifically, 8% to 15%) as described above. In this case, in order to keep the screen brightness after passing through the surface member 30 within the above range, the screen brightness of the variable display unit 120 (specifically, the display panel 121) itself should be, for example, 400 cd / m 2 More than 3000cd / m 2 The following is the result.

[0033] The surface member 30 can be made of, for example, real materials such as wood grain, cloth grain, leather, or stone, or resin materials that imitate these, or transparent or translucent resin materials that have been decorated by painting or printing on the surface, so that information can be displayed without the presence of the display 100 being noticeable.

[0034] The surface member 30 may have a certain hard coating (not shown) on the surface 39. The surface 39 of the surface member 30 may be frequently touched by users. For example, when the information display device 10 is used in equipment on an aircraft, it may be touch-operated by an unspecified number of people. Therefore, the hard coating preferably has a hardness of 2H (JIS standard) or higher, for example. This makes it possible to prevent scratches. The hard coating may be a thin layer to maintain the feel of the surface member 30. The thickness of the hard coating is, for example, 5 μm or more and 20 μm or less.

[0035] The surface member 30 may also have a reflective layer (not shown) on the rear surface 38. The reflective layer is made of a material such as a half mirror, and has the property of reflecting external light but transmitting light from the display 100. By disposing the reflective layer on the rear surface 38 of the surface member 30, the display 100 can be made less visible. The external light reflecting property of the reflective layer prevents the presence of the display 100 itself from being seen through the surface member 30, while the light transmitting property of the reflective layer makes it possible to present the display content of the display 100 to the user.

[0036] The structure 40 is a block made of resin, metal, or the like. The structure 40 is held in a predetermined position inside the wall 20 (see FIG. 1) by, for example, supports or the like. The surface member 30 and the display 100 are installed on the structure 40.

[0037] The structure 40 has a curved shape in at least a portion of its surface 49 that corresponds to the curved shape of the surface member 30. In the illustrated example, a step is provided on the surface 49 of the structure 40 for installing the fixing part 110. The fixing part 110 is fixed to the structure 40. In the illustrated example, the fixing part 110 has a hole for inserting a bolt 50 therethrough, and the fixing part 110 is detachably fixed to the structure 40 by the bolt 50. The method for fixing the fixing part 110 to the structure 40 is not particularly limited. The fixing part 110 is not fixed to the surface member 30.

[0038] Furthermore, the variable display unit 120 is not adhered to the structure 40. In other words, there is no adhesive force between the variable display unit 120 and the structure 40 due to bonding with an adhesive or the like, and the variable display unit 120 and the structure 40 can be separated without damaging the variable display unit 120 or the structure 40. In the illustrated example, the surface 49 of the structure 40 is in close contact with the back surface 129 of the variable display unit 120, but a gap may exist between the surface 49 and the back surface 129.

[0039] Next, a detailed configuration of the display 100 included in the information display device 10 will be described. FIG. 4 is a schematic top view of the display according to this embodiment. FIG. 5 is a schematic side view of the display according to this embodiment. FIG. 6 is a schematic cross-sectional view of a variable display unit in the display according to this embodiment. FIG. 4 is a plan view of the display 100 as viewed from the positive side in the z-axis direction (in other words, the surface 128 side of the variable display unit 120). FIG. 5 is a plan view of the display 100 as viewed from the negative side in the y-axis direction. FIG. 6 shows a cross section taken along line VI-VI in FIG. 4. In FIG. 4, the outline of the display surface 121a of the display panel 121 disposed inside the variable display unit 120 and the outline of the fixed unit 110 at a position covered by the variable display unit 120 are indicated by dashed lines. In FIG. 4, a dotted pattern is applied to the area corresponding to the display surface 121a. In FIG. 5, the outline of the rigid substrate 111 disposed inside the fixed unit 110 is indicated by dashed lines. Furthermore, for ease of viewing, the length in the z-axis direction is exaggerated in Fig. 6. That is, the thickness of each component is exaggerated in Fig. 6.

[0040] As shown in FIGS. 4 and 5, the display 100 has a fixed portion 110, a variable display portion 120, and a connection cable .

[0041] The fixed unit 110 is a rigid housing. The fixed unit 110 has higher rigidity than the variable display unit 120. The fixed unit 110 cannot be bent manually. The shape of the fixed unit 110 is, for example, a rectangular parallelepiped, but is not particularly limited. The material forming the fixed unit 110 is also not particularly limited as long as it is a material with sufficient rigidity to prevent easy deformation. The fixed unit 110 includes, for example, a metal plate or resin plate that forms the bottom plate of the housing, and a resin frame that forms side walls that stand upright from the bottom surface. The positive side of the fixed unit 110 in the z-axis direction is covered by the variable display unit 120. The fixed unit 110 is disposed on the back surface 129 side of the variable display unit 120 and is fixed to the back surface 129. The fixed unit 110 has a rigid substrate 111 inside. The rigid substrate 111 is a substrate on which a circuit for driving the display panel 121 is provided.

[0042] The variable display unit 120 is a flexible, plate-like display component. The variable display unit 120 can be bent, for example, manually. Information is displayed on a surface 128 of the variable display unit 120. The variable display unit 120 can be deformed, for example, by elastic deformation, to conform to the curved shape of the surface member 30. The variable display unit 120 has a plate-like shape. The thickness of the variable display unit 120 is, for example, smaller than the length of the fixed unit 110 in the thickness direction (z-axis direction) of the variable display unit 120. The thickness of the variable display unit 120 is, for example, 1 mm or more and 5 mm or less. The shape of the variable display unit 120 in a planar view is, for example, rectangular, but is not particularly limited. In this specification, a planar view refers to a view perpendicular to the surface 128 when the variable display unit 120 is not bent.

[0043] A portion of the variable display unit 120 is fixed to the fixed unit 110. Specifically, one end of the variable display unit 120, which is the end on the negative side in the x-axis direction, is fixed to the fixed unit 110. There are no particular limitations on the method for fixing a portion of the variable display unit 120 to the fixed unit 110, and for example, double-sided adhesive tape or adhesive (not shown) may be used.

[0044] The variable display unit 120 includes a portion that extends outward in the x-axis direction from the position of the end surface 110a of the fixed unit 110. The end surface 110a of the fixed unit 110 is the end surface on the positive side in the x-axis direction.

[0045] For example, in a plan view, the variable display unit 120 is divided into a variable area A1, which is a deformable area that is not fixed to the fixed unit 110, and a fixed area A2, which is a area that is fixed to the fixed unit 110. In the variable area A1, the back surface 129 of the variable display unit 120 is not constrained by the fixed unit 110. The variable area A1 is an area that includes the other end of the variable display unit 120, which is the end on the positive side in the x-axis direction, and this other end is not fixed to anything, so the variable area A1 in the variable display unit 120 deforms due to an external force. On the other hand, the fixed area A2 in the variable display unit 120 does not deform even when subjected to an external force and remains fixed to the fixed unit 110. The length of the variable area A1 in the x-axis direction is longer than the length of the fixed area A2 in the x-axis direction.

[0046] 4 and 5, the variable area A1 is an area of ​​the variable display unit 120 that does not overlap with the fixed portion 110 in a planar view, and the fixed area A2 is an area of ​​the variable display unit 120 that overlaps with the fixed portion 110 in a planar view. Note that, of the area of ​​the variable display unit 120 that overlaps with the fixed portion 110 in a planar view, not all of it needs to be fixed to the fixed portion 110; for example, only a portion of the variable area A1 may overlap with the fixed portion 110 in a planar view.

[0047] 6, the variable display unit 120 has a display panel 121, a cover material 122, a flexible housing 123, a touch panel 124, and a transparent adhesive sheet 125. It is sufficient that the variable display unit 120 has at least the display panel 121, the cover material 122, and the flexible housing 123.

[0048] The display panel 121 has light-emitting elements and displays information by the light emitted by the light-emitting elements. The display panel 121 is, for example, an OLED (Organic Electro Luminescence Diode) panel or a matrix LED (Light Emitting Diode) panel.

[0049] The display panel 121 has a display surface 121a, which is a surface on which light from the light-emitting elements is emitted and information is displayed. The information displayed on the display surface 121a is displayed on the surface 128 of the variable display unit 120. The display surface 121a is at least a part of the surface of the display panel 121. For example, the display panel 121 has light-emitting elements arranged in a matrix, and the display surface 121a corresponds to the area where the light-emitting elements arranged in the matrix are located. The display panel 121 is housed in a flexible housing 123. In the example shown in FIG. 4, the display surface 121a slightly overlaps with the fixed part 110 in a planar view, but it does not have to overlap with the fixed part 110. The area where the display surface 121a overlaps with the fixed part 110 is, for example, 5% or less of the area of ​​the display surface 121a. Furthermore, the display surface 121a does not overlap with the rigid substrate 111 in a planar view, for example. By overlapping the end of the display surface 121a with the fixed part 110, it is possible to reduce the load applied to the connector (not shown) that connects the rigid substrate 111 and the display panel 121 when the variable display part 120 is deformed, while maintaining the deformation area of ​​the variable display part 120. This makes it possible to reduce the failure of the display panel 121.

[0050] The display panel 121 is a flexible panel and has flexibility. In the display panel 121, for example, light emitting elements and electrodes that supply voltage to the light emitting elements are arranged on a flexible substrate such as a resin film substrate.

[0051] The cover material 122 is disposed on the display surface 121a side of the display panel 121. The cover material 122 faces the display surface 121a of the display panel 121 and completely covers the display surface 121a of the display panel 121. The light transmittance of the cover material 122 is higher than the light transmittance of the flexible housing 123. This allows the variable display unit 120 to display information more clearly. It also makes it possible to lower the screen brightness of the display panel 121, thereby reducing power consumption. Note that the light transmittance here refers to the light transmittance in the region that overlaps with the display surface 121a in a plan view.

[0052] The cover material 122 is, for example, an amorphous resin film made of an amorphous resin. Examples of amorphous resins include polycarbonate resin, acrylic resin, and urethane resin. The amorphous resin contains an amorphous polymer as a base material and, if necessary, a resin additive such as a flame retardant. The cover material 122 may be made of polycarbonate resin, among the above amorphous resins. This allows for high light transmittance and high flame retardancy. The cover material 122 has, for example, a flame retardancy of V-2 or higher according to the UL94 standard. The cover material 122 may also have a flame retardancy of V-0 according to the UL94 standard.

[0053] The elastic modulus of the material making up the cover material 122 is, for example, higher than the elastic modulus of the material making up the flexible housing 123. The elastic modulus of the material making up the cover material 122 may be 10 times or more the elastic modulus of the material making up the flexible housing 123. The elastic modulus of the material making up the cover material 122 is, for example, 1000 MPa or more and 5000 MPa or less. The elastic modulus of the material making up the flexible housing 123 is, for example, 0.5 MPa or more and 100 MPa or less. Note that the elastic modulus here is the tensile elastic modulus at room temperature (specifically, 25°C).

[0054] At a position overlapping the display panel 121 in a plan view, the thickness L1 of the cover material 122 is thinner than the thickness L2 of the flexible housing 123. This thin thickness L1 of the cover material 122 allows the light transmittance of the cover material 122 to be increased. Furthermore, the thin thickness L1 of the cover material 122 makes the cover material 122 more flexible and easier to bend, allowing it to conform to the curved shape of the surface member 30. Furthermore, the increased thickness L2 of the flexible housing 123 allows the flexible housing 123 to improve its ability to protect the display panel 121. The thickness L1 of the cover material 122 is, for example, 0.1 mm or more and 0.5 mm or less. The thickness L2 of the flexible housing 123 is, for example, 0.5 mm or more and 3 mm or less.

[0055] The flexible housing 123 is a flexible container that houses the display panel 121. The flexible housing 123 covers the display panel 121 from the side opposite to the display surface 121a of the display panel 121. The flexible housing 123 is provided with a recess 123a that houses the display panel 121. The display panel 121 is disposed above the bottom surface of the recess 123a, and is entirely located in the internal space of the flexible housing 123 formed by the recess 123a. The recess 123a of the flexible housing 123 houses the touch panel 124 and the transparent adhesive sheet 125 together with the display panel 121.

[0056] In the example shown in Fig. 6, a gap is formed between the bottom surface of the recess 123a and the display panel 121. This reduces the resistance to deformation of the variable display unit 120, making it easier for the variable display unit 120 to deform. Gaps are also formed between the side wall surfaces of the recess 123a and the display panel 121, the touch panel 124, and the transparent adhesive sheet 125. Note that at least some of these gaps may be filled with a flexible material such as an elastic body. Alternatively, the display panel 121, the touch panel 124, and the transparent adhesive sheet 125 may be housed in the recess 123a so that at least some of these gaps are not formed.

[0057] A cover material 122 is arranged to cover the recess 123a of the flexible housing 123, and the recess 123a of the flexible housing 123 is covered by the cover material 122. The display panel 121 is covered from all directions by the cover material 122 and the flexible housing 123. The flexible housing 123 and the cover material 122 are bonded together by, for example, double-sided adhesive tape or an adhesive (not shown).

[0058] The flexible housing 123 is made of an elastic material such as rubber or elastomer. The rubber used in the flexible housing 123 may be silicone rubber, which provides high flame resistance. The flexible housing 123 is formed as a single unit, but may also be formed by joining multiple members together.

[0059] The outer shape of the variable display unit 120 is roughly determined by the flexible housing 123. In a plan view, the shape of the variable display unit 120 matches the shape of the flexible housing 123, for example. The outer shape of the variable display unit 120 is determined by the flexible housing 123 and the cover material 122, for example.

[0060] The touch panel 124 detects user inputs based on changes in capacitance, pressure, or light, etc. The touch panel 124 is disposed between the display panel 121 and the cover material 122. A specific example of the touch panel 124 is a capacitance-type touch panel. Note that a touch sensor may be disposed instead of the touch panel 124.

[0061] The transparent adhesive sheet 125 is arranged so that no gap is formed between the display panel 121 and the cover material 122. In the example shown in Fig. 6, the variable display unit 120 includes a transparent adhesive sheet 125 arranged between the display panel 121 and the touch panel 124 to adhere to the display panel 121 and the touch panel 124, and a transparent adhesive sheet 125 arranged between the touch panel 124 and the cover material 122 to adhere to the touch panel 124 and the cover material 122. The transparent adhesive sheet 125 is, for example, an OCA (Optical Clear Adhesive) made of a transparent resin such as a silicone resin, an acrylic resin, or a urethane resin.

[0062] 4 and 5, the connection cable 130 is connected to the fixed part 110. The connection cable 130 is a cable for connecting the display 100 to an external device. Power and signals required for driving the display 100 are supplied to the display 100 via the connection cable 130. Note that the display 100 does not necessarily have to have the connection cable 130, and may have a connector to which an external cable is connected instead of the connection cable 130.

[0063] [Effects, etc.] As described above, information display device 10 according to this embodiment includes surface member 30 having a curved surface 39 and installed on structure 40, and display 100. Display 100 includes fixed portion 110 fixed to structure 40, and variable display portion 120 that displays information and is shape-deformable, with a portion of variable display portion 120 fixed to fixed portion 110. Variable display portion 120 is disposed between surface member 30 and structure 40 so as to display information via surface member 30, and is disposed in a shape that conforms to surface member 30. Display 100 according to this embodiment is a display used in information display device 10.

[0064] With this, while the display 100 is fixed to the structure 40 by the fixing portion 110, the variable display portion 120, which is the portion that displays information, is deformable and is arranged in a shape that conforms to the surface member 30. Therefore, in the information display device 10 that displays information via the surface member 30, it is possible to accommodate the curved shape of the surface member 30.

[0065] In the information display device 10 according to the present embodiment, the variable display unit 120 may be fixed to the fixed unit 110 at one end of the variable display unit 120 .

[0066] This makes it easy to increase the movable range of the variable display section 120.

[0067] Furthermore, in the information display device 10 according to the present embodiment, the variable display unit 120 does not have to be adhered to the surface member 30 and the structure 40.

[0068] This makes it possible to separate the variable display unit 120 from the surface member 30 and the structure 40 without damaging the variable display unit 120, the surface member 30, and the structure 40. Therefore, the display 100 can be easily removed for maintenance.

[0069] Furthermore, in the information display device 10 according to the present embodiment, the variable display unit 120 may be arranged in a shape that conforms to the surface member 30 by the force with which the surface member 30 presses the variable display unit 120 .

[0070] According to this, by pressing the variable display section 120 with the surface member 30, it is possible to prevent a gap from being formed between the surface member 30 and the variable display section 120, and it is possible to prevent blurring of the information display.

[0071] Furthermore, in the information display device 10 according to this embodiment, when the variable display section 120 is turned on, only the information displayed on the variable display section 120 of the display 100 may be visible through the surface member 30.

[0072] This allows information to be displayed without making the user aware of the presence of display 100.

[0073] Furthermore, in the information display device 10 according to this embodiment, the variable display unit 120 has a display panel 121 that has light-emitting elements and displays information by emitting light from the light-emitting elements, and the surface member 30 may be larger than the display panel 121.

[0074] According to this, the edge of the surface member 30 is not disposed in a position overlapping with the display panel 121, so that the presence of the display 100 is less noticeable to the user.

[0075] Furthermore, in the information display device 10 according to this embodiment, the variable display unit 120 may include a display panel 121 having a light-emitting element and displaying information by emitting light from the light-emitting element, a cover material 122 covering a display surface 121a of the display panel 121, and a flexible housing 123 having a recess 123a for accommodating the display panel 121, which is flexible and covers the display panel 121 from the side opposite the display surface 121a of the display panel 121.

[0076] This makes it possible to realize a deformable variable display section 120 without exposing the display panel 121.

[0077] In the information display device 10 according to the present embodiment, the light transmittance of the cover material 122 may be higher than the light transmittance of the flexible housing 123 .

[0078] This allows the variable display section 120 to display information more clearly. Also, it becomes possible to lower the screen brightness of the display panel 121, thereby reducing power consumption.

[0079] In information display device 10 according to the present embodiment, cover material 122 may be made of polycarbonate resin, and flexible housing 123 may be made of silicone rubber.

[0080] This allows the variable display section 120 to have high light transmittance and high flame retardancy.

[0081] Furthermore, in information display device 10 according to the present embodiment, thickness L1 of cover material 122 may be thinner than thickness L2 of flexible housing 123 at a position overlapping display panel 121 in a plan view.

[0082] According to this, the thickness L1 of the cover material 122 is small, which increases the light transmittance of the cover material 122 and makes the cover material 122 more flexible, allowing it to more easily follow the curved shape of the surface member 30. Furthermore, the thickness L2 of the flexible housing 123 is large, which increases the protection performance of the flexible housing 123 for the display panel 121.

[0083] Furthermore, the information display device 10 according to this embodiment may be installed in a mobile body.

[0084] According to this, the information display device 10 is installed on a mobile body which often has curved walls or the like.

[0085] [Another example of how to arrange the variable display section] In the above description, the variable display unit 120 is arranged in a shape that conforms to the surface member 30 by the force that presses the variable display unit 120 with the surface member 30, but this is not limiting. Below, another method for arranging the variable display unit 120 in a shape that conforms to the surface member 30 will be described.

[0086] First, a first alternative example of a method for arranging the variable display unit 120 in a shape that conforms to the surface member 30 will be described. Fig. 7 is a schematic perspective view for explaining a surface member and structure having another configuration according to this embodiment. Fig. 8 is a schematic side view showing a state in which the display according to this embodiment is installed on a structure having another configuration.

[0087] 7 and 8, the surface member 30A is formed integrally with the structure 40A, and the surface member 30A is installed on the structure 40A in advance. A gap 60 is formed between the surface member 30A and the structure 40A, and the gap 60 has a shape that follows the curved shape of the surface member 30A. The gap 60 may be a through gap or a gap with a bottom.

[0088] 7 and 8, the display 100 is inserted into the gap 60 while the variable display unit 120 is deformed to fit the shape of the gap 60, so that the variable display unit 120 is arranged in a shape that conforms to the surface member 30A. The variable display unit 120 is brought into close contact with the surface member 30A by, for example, the elastic force of the variable display unit 120. The fixed unit 110 is fixed to the structure 40A within the gap 60 by bolts 50 or the like.

[0089] Next, a second example of a method for arranging the variable display unit 120 in a shape that conforms to the surface member 30 will be described. FIG. 9 is a schematic cross-sectional view showing a state in which the variable display unit according to this embodiment is arranged along a guide provided on a structure. FIG. 10 is a schematic cross-sectional view showing a state in which the variable display unit according to this embodiment is arranged along a guide provided on a surface member. FIGS. 9 and 10 show cross sections of the variable display units 120B and 120 at positions corresponding to FIG. 6. Also, detailed internal cross-sectional structures of the variable display units 120B and 120 are omitted from FIGS. 9 and 10.

[0090] In the example shown in FIG. 9, a guide 41 is provided on the structure 40B. A portion of the surface of the structure 40B protrudes, and the guide 41 is a groove provided in the protruding portion of the structure 40B, and extends to correspond to the curved shape of the surface member 30. The guide 41 is provided at a position separated from the surface member 30 when the surface member 30 is installed on the structure 40B. The guide 41 may have a rail. Two guides 41 are provided facing each other so that the variable display unit 120B can be sandwiched between them.

[0091] 9 has the same configuration as the variable display unit 120, except that it has a guided portion 127 having a shape corresponding to the guide 41. The guided portion 127 is a protruding portion formed on the side surface of the variable display unit 120B. The guided portion 127 is thinner than the central portion of the variable display unit 120B because the surface member 30 side of the variable display unit 120B is recessed. The guided portion 127 is, for example, a part of the flexible housing 123 (see FIG. 6). Note that the guided portion 127 may be formed of a separate member from the flexible housing 123 and connected to the flexible housing 123.

[0092] 9, the guided portion 127 of the variable display unit 120B is arranged along the guide 41, and thus the variable display unit 120B is arranged in a shape that follows the surface member 30. Since the position and shape of the variable display unit 120B are determined by the guide 41, it is possible to deform and arrange the variable display unit 120B so that it comes into close contact with the surface member 30 depending on the design of the guide 41.

[0093] 10, a guide 33 is provided on the surface member 30B. The surface member 30B has a plate- or film-shaped main body 31 having the same configuration as the above-described surface member 30, and a guide portion 32 for forming the guide 33 on the back surface side of the main body 31. The guide portion 32 extends in accordance with the curved shape of the surface member 30B. The guide portion 32 has an L-shaped cross section in a direction perpendicular to the extension direction of the guide portion 32, and is formed on the back surface of the main body 31, thereby providing a groove-shaped guide 33 on the surface member 30B. Two guides 33 are provided facing each other so that the variable display unit 120 can be sandwiched therebetween.

[0094] 10, the variable display unit 120 is arranged in a shape that follows the surface member 30B (specifically, the main body 31) by arranging the ends along the guides 33. Since the position and shape of the variable display unit 120 are determined by the guides 33, it is possible to deform and arrange the variable display unit 120 so that it comes into close contact with the main body 31 of the surface member 30B depending on the design of the guides 33.

[0095] Next, a third alternative example of a method for arranging the variable display section 120 in a shape that conforms to the surface member 30 will be described. Fig. 11 is a schematic top view showing a display with another configuration according to this embodiment.

[0096] A display 100C shown in FIG. 11 has a configuration in which a fixed portion 140 is added to the above-described display 100. In the display 100C, the fixed portion 140 is connected to the other end of the variable display unit 120 in the x-axis direction, which is the end on the positive side in the x-axis direction. The fixed portion 140 is a rigid plate or block made of resin, metal, or the like. The fixed portion 140 has higher rigidity than the variable display unit 120. The fixed portion 140 cannot be bent by human force. For example, the fixed portion 140 has holes formed therein, and the fixed portion 140 is fixed to the structure 40 by bolts or the like inserted through the holes. In the display 100C, the variable display unit 120 is arranged in a shape that conforms to the surface member 30 by fixing the fixed portions 110 and 140, which are arranged at both ends of the variable display unit 120, to the structure 40.

[0097] [Variations] Next, a modified example of the embodiment will be described. The following description will focus on the differences from the above embodiment, and the description of the commonalities will be omitted or simplified.

[0098] FIG. 12 is a schematic bottom view of a display according to this modification. FIG. 13 is a schematic side view of a display according to this modification. FIG. 12 is a plan view of the display 101 when viewed from the negative side in the z-axis direction (in other words, the rear surface 129 side of the variable display unit 120). FIG. 13 is a plan view of the display 101 when viewed from the negative side in the y-axis direction. In FIG. 12, the outline of the reinforcing unit 150 at the position covered by the fixing unit 110 is indicated by a dashed line. In FIG. 12, the density of dots added in the region of the reinforcing unit 150 on the positive side in the x-axis direction from the end surface 110a corresponds to the rigidity of the reinforcing unit 150, with a higher dot density indicating a higher rigidity. In addition, although the connection cable 130 shown in FIGS. 4 and 5 is omitted in FIGS. 12 and 13, the display 101 may include the connection cable 130.

[0099] The information display device according to this modification has a configuration in which the display 100 of the information display device 10 described above is replaced with a display 101. As shown in Figures 12 and 13, the display 101 according to this modification is different from the display 100 described above mainly in that it further includes a reinforcing portion 150. The display 101 has a configuration in which the reinforcing portion 150 is added to the configuration of the display 100.

[0100] The reinforcing portion 150 is a plate-shaped reinforcing member. The reinforcing portion 150 is made of, for example, wood, resin, or metal. In the example shown in FIG. 12 , the reinforcing portion 150 has a rectangular shape in a planar view. The reinforcing portion 150 is disposed on the back surface 129 of the variable display unit 120. The reinforcing portion 150 overlaps the variable display unit 120 in a planar view. The rigidity of the reinforcing portion 150 is lower than that of the fixed portion 110, and the reinforcing portion 150 is deformable together with the variable display unit 120. The arrangement of the reinforcing portion 150 is not particularly limited as long as it is deformable together with the variable display unit 120 and does not interfere with the display of information by the variable display unit 120. For example, the reinforcing portion 150 may be disposed so as to be embedded in the back surface 129 of the variable display unit 120. The reinforcing portion 150 may be embedded in the flexible housing 123 (see FIG. 6 ) of the variable display unit 120.

[0101] The reinforcing portion 150 includes a portion that extends in the x-axis direction from the position of the end surface 110a of the fixed portion 110 so as to move away from the fixed portion 110. In the example shown in Fig. 12 and Fig. 13, in the x-axis direction, the tip of the reinforcing portion 150 on the positive side of the x-axis direction, which is the distal end of the reinforcing portion 150 with respect to the fixed portion 110, is closer to the fixed portion 110 than the tip of the variable display portion 120 on the positive side of the x-axis direction. Note that in the x-axis direction, the tip of the reinforcing portion 150 on the positive side of the x-axis direction may be in the same position as the tip of the variable display portion 120 on the positive side of the x-axis direction, or may be farther from the fixed portion 110 than the tip of the variable display portion 120 on the positive side of the x-axis direction.

[0102] 12 and 13, a portion of the reinforcing portion 150 overlaps with the fixed portion 110 in a plan view, and is sandwiched between the fixed portion 110 and the variable display portion 120. The reinforcing portion 150 extends outward from the fixed portion 110 in the x-axis direction from the position of the end surface 110a of the fixed portion 110. At least a portion of the reinforcing portion 150 is fixed to at least one of the fixed portion 110 and the variable display portion 120. The reinforcing portion 150 may be integrated with the fixed portion 110 or the variable display portion 120.

[0103] The stiffness of the reinforcement part 150 decreases in the x-axis direction as it moves away from the position of the end surface 110a of the fixed part 110 (in other words, as it moves toward the distal end of the reinforcement part 150 relative to the fixed part 110). The stiffness here refers to stiffness against bending in the thickness direction (z-axis direction) of the variable display part 120. In other words, the reinforcement part 150 becomes more easily bent in the x-axis direction as it moves away from the position of the end surface 110a of the fixed part 110.

[0104] In the example shown in FIGS. 12 and 13 , the reinforcement portion 150 is a member having a constant thickness (length in the z-axis direction) and a constant width (length in the y-axis direction). The bending strength of the material constituting the reinforcement portion 150 decreases with increasing distance from the end surface 110a of the fixed portion 110, resulting in a decrease in rigidity. The reinforcement portion 150 has, for example, a plurality of slits extending in the y-axis direction. The density of the slits formed in the reinforcement portion 150 per unit area increases with increasing distance from the end surface 110a of the fixed portion 110. As a result, the number of slits in the material constituting the reinforcement portion 150 increases with increasing distance from the end surface 110a of the fixed portion 110, resulting in a decrease in bending strength. Note that the method for decreasing the strength of the material of the reinforcement portion 150 with increasing distance from the end surface 110a of the fixed portion 110 is not limited to the formation of slits, and is not particularly limited. For example, the density or elastic modulus of the material of the reinforcement portion 150 may decrease with increasing distance from the end surface 110a of the fixed portion 110.

[0105] As described above, display 101 according to this modification has fixed portion 110 which is a rigid housing, variable display portion 120 which displays information and is capable of changing its shape, a portion of which is fixed to fixed portion 110 and which extends outward from end face 110a of fixed portion 110 in the x-axis direction, and reinforcing portion 150 which overlaps variable display portion 120 in a plan view and is capable of changing shape together with variable display portion 120. Reinforcing portion 150 includes a portion which extends away from end face 110a of fixed portion 110 in the x-axis direction, and its rigidity decreases with increasing distance from end face 110a of fixed portion 110.

[0106] The vicinity of the position of the variable display unit 120 overlapping with the end surface 110a of the fixed unit 110 in a plan view is a portion that is likely to locally bend when the variable display unit 120 is deformed. In the display 101, the reinforcing unit 150 is disposed, including a portion that extends from the position of the end surface 110a of the fixed unit 110 away from the fixed unit 110, and the reinforcing unit 150 can make the variable display unit 120 less likely to locally bend. Furthermore, if the rigidity of the distal end of the reinforcing unit 150 relative to the fixed unit 110 is high, that is, if the reinforcing unit 150 is less likely to bend, the variable display unit 120 is more likely to locally bend at the distal end of the reinforcing unit 150 relative to the fixed unit 110. However, in the display 101, the rigidity of the reinforcing unit 150 decreases with increasing distance from the position of the end surface 110a of the fixed unit 110, and therefore the variable display unit 120 is less likely to locally bend even at the distal end of the reinforcing unit 150 relative to the fixed unit 110. 13, even if a voltage is applied to the end of the variable display unit 120 on the positive side in the x-axis direction, the variable display unit 120 is prevented from bending locally, and the variable display unit 120 is more likely to bend overall. Therefore, damage to the variable display unit 120 can be prevented.

[0107] The form of the reinforcing portion 150 is not limited to the examples shown in FIGS. 12 and 13. FIG. 14 is a schematic bottom view of a display having a reinforcing portion of a first example according to this modified example. FIG. 15 is a schematic bottom view of a display having a reinforcing portion of a second example according to this modified example. FIG. 16 is a schematic bottom view of a display having a reinforcing portion of a third example according to this modified example. FIGS. 14, 15, and 16 are plan views of displays 101A, 101B, and 101C, respectively, as viewed from the negative side in the z-axis direction (in other words, the rear surface 129 side of the variable display unit 120). In FIGS. 14, 15, and 16, the outlines of the reinforcing portions 150A, 150B, and 150C at positions covered by the fixed portion 110 are indicated by dashed lines.

[0108] 14, 15, 16 and 17 show displays 101A, 101B, 101C and 101D having a configuration in which the reinforcing portion 150 in the display 101 is replaced with reinforcing portions 150A, 150B, 150C and 150D, respectively.

[0109] 14, 15, and 16, the width (length in the y-axis direction) of the reinforcement parts 150A, 150B, and 150C decreases in the x-axis direction as they move away from the end surface 110a of the fixed part 110, thereby decreasing their rigidity. In the example shown in FIGS. 14, 15, and 16, the width of the reinforcement parts 150A, 150B, and 150C at the position of the end surface 110a of the fixed part 110 in the x-axis direction is the same as the width of the variable display unit 120.

[0110] 14 and 15 are linear and narrow in width as they move away from the end face 110a of the fixed part 110, forming a triangle in plan view. Reinforcement part 150C shown in Fig. 16 is curved and convex on the side farther from the fixed part 110, narrowing in width as they move away from the end face 110a of the fixed part 110, forming a semicircle or semiellipse in plan view.

[0111] 15, a portion of the reinforcing portion 150B extending from the end surface 110a of the fixed portion 110 in the x-axis direction so as to move away from the fixed portion 110 is divided into two. In the reinforcing portion 150B, the width of each of the two divided portions decreases with increasing distance from the end surface 110a of the fixed portion 110. Note that the above portion of the reinforcing portion 150B may be divided into three or more portions. The above portion of the reinforcing portion 150B may also be curved and have a narrower width, like the reinforcing portion 150C.

[0112] 15, in a plan view, the tip of each of the two divided parts of the reinforcement part 150B on the positive side in the x-axis direction is located at the outer edge in the y-axis direction of the variable display part 120. Note that in a plan view, the tip of each of the two divided parts on the positive side in the x-axis direction may be located inside the outer edge in the y-axis direction of the variable display part 120.

[0113] Fig. 17 is a schematic side view of a display having a reinforcing portion of a fourth example according to this modification. Fig. 17 is a plan view of the display 101 as viewed from the negative side in the y-axis direction.

[0114] 17, the thickness (length in the z-axis direction) of the reinforcement portion 150D decreases with increasing distance from the end surface 110a of the fixed portion 110 in the x-axis direction, thereby decreasing rigidity.
