Description

Technical Field

[0001] This disclosure relates to panel bodies and display devices. Background Technology

[0002] For display devices such as monitors used in navigation systems, glass panels are sometimes used. With the desire for larger screen sizes in display devices, the handling of sheet-like components such as glass used in the panels becomes difficult during transportation and assembly. Furthermore, in applications such as display devices intended for automotive use, strict safety standards exist regarding the prevention of breakage and damage to sheet-like components. Avoiding damage caused by slight torsion during assembly of sheet-like components has become a challenge.

[0093] Hereinafter, embodiments of the panel body of this disclosure will be described with reference to the accompanying drawings.

[0094] (First Embodiment)

[0095] (Example of panel structure)

[0096] Figures 1A to 1C This is a schematic diagram illustrating an example of the structure of the panel body 10 according to an embodiment. Figure 1A This is a perspective view of panel 10 as seen from the first side. Figure 1B This is a perspective view of panel 10 viewed from the second side. Figure 1C This is a partially enlarged sectional view of panel 10.

[0097] The panel body 10 has a plate-shaped member 12 and a frame 14.

[0098] The plate-shaped member 12 is a generally flat plate-shaped member. The plate-shaped member 12 is made of materials such as glass, stone, wood, paper, or fabric. The glass is, for example, optical glass. Optical glass is glass that has undergone optical processing to possess characteristics suitable for use as an optical element in a display device, such as low wavelength dependence of transmittance and high refractive index. In this embodiment, the plate-shaped member 12 is described assuming it is a plate-shaped glass made of glass. However, as mentioned above, the material of the plate-shaped member 12 is not limited to glass.

[0099] Due to the characteristics of the frame 14 described later, the plate member 12 can have a thickness of, for example, 3 mm or less. The plate member 12 can also have a thickness of 1.2 mm or more but less than 1.5 mm, or it can also have a thickness of 0.8 mm or less.

[0100] Such thin-walled plate-shaped members 12 are easily damaged and require careful handling. In the panel body 10 of the embodiment, as described below, a frame 14 is integrally provided around the plate-shaped member 12, which protects the plate-shaped member 12.

[0101] Frame 14 is a resin component, for example, made of carbon fiber reinforced thermoplastic (CFRTP). CFRTP is a fiber-reinforced plastic obtained by using carbon fiber (CF) as a reinforcing material in a thermoplastic resin base material. By using a wide range of thermoplastic resins as the base material, it is possible to select resins with desired properties from various series for CFRTP.

[0102] The frame 14 of the panel body 10 in this embodiment has the characteristics of high flame retardancy and a thermal shrinkage rate similar to that of the plate member 12. In addition, compared with magnesium die castings that are often used to protect glass, the frame 14 has a specific gravity that is about 30% lower and has roughly the same strength as magnesium die castings.

[0103] The frame 14 is integrally formed with the plate-shaped member 12, and seamlessly covers the end face of the plate-shaped member 12. That is, the frame 14 has the following structure: it is integrally formed with the plate-shaped member 12 in such a way that it continuously and seamlessly covers the end face of the plate-shaped member 12, and does not have an inlet groove or fitting groove for the plate-shaped member 12 to be inserted.

[0104] The frame 14 is preferably configured to clamp the plate-shaped member 12 from the front and back sides.

[0105] In detail, such as Figure 1C As shown, for example, the frame 14 has a frame-shaped first pressing portion 14A extending from the end face of the plate member 12 toward the first surface 12A and a frame-shaped second pressing portion 14B extending from the end face of the plate member 12 toward the second surface 12B.

[0106] The first pressing portion 14A surrounds the edge of the first surface 12A of the plate member 12 in a frame-like manner. It may extend longer toward the center of the plate member 12 compared to the second pressing portion 14B that surrounds the edge of the second surface 12B of the plate member 12 in a frame-like manner.

[0107] In this way, the frame 14 seamlessly surrounds the plate-shaped member 12 and does not have, for example, a guide groove or fitting groove for the plate-shaped member 12 to be inserted. The frame 14, which does not have seams, is also excellent in terms of appearance design, and for example, it can be directly applied to display devices without surface coating.

[0108] Furthermore, by integrally forming a frame 14 around the plate-shaped member 12, the overall torsional stiffness of the panel body 10 is improved. This suppresses torsion at the diagonals of, for example, the rectangular plate-shaped member 12, facilitating assembly into display devices and the like. Additionally, since the end faces of the plate-shaped member 12 are protected by the frame 14, breakage such as cracks and chips at the end faces of the plate-shaped member 12 is suppressed. Moreover, the overall strength of the plate-shaped member 12 against impacts and collisions is improved. This simplifies the handling of the panel body 10 during transport and assembly.

[0109] In addition, the frame 14 can also be anisotropic.

[0110] The anisotropy of the frame 14 means that the frame 14 includes multiple regions in which the carbon fibers contained in the carbon fiber reinforced resin constituting the frame 14 have different orientation directions. Specifically, for example, in the frame 14, the orientation directions of the carbon fibers contained in the first pressing portion 14A and the orientation directions of the carbon fibers contained in the second pressing portion 14B are different. More specifically, for example, the orientation directions of the carbon fibers contained in the first pressing portion 14A and the orientation directions of the carbon fibers contained in the second pressing portion 14B are mutually orthogonal.

[0111] Thus, the anisotropy of the frame 14 further enhances its strength. Furthermore, by adjusting the orientation of the carbon fibers in each region of the frame 14 after it has been divided into multiple regions according to the strength required for the intended application, a frame 14 with the required strength for that application can be provided. This anisotropy of the frame 14 can be achieved by adjusting the filling direction of the carbon fiber reinforcing resin during manufacturing. The manufacturing method of the panel body 10 including the frame 14 will be described later.

[0112] Alternatively, the frame 14 may be a structure that is at least partially colored. Alternatively, the frame 14 may be a structure comprising multiple regions that are colored with different colors. For example, by using different colors of the carbon fiber reinforced resin for each region during manufacturing, a frame 14 colored with multiple colors can be constructed. A method for manufacturing the panel body 10 including the frame 14 will be described later.

[0113] (Manufacturing method of panel body)

[0114] Next, use Figures 2-6 The manufacturing method of the panel body 10 of the embodiment will be described.

[0115] Figure 2 This is a schematic diagram illustrating an example of the structure of a molding apparatus 60 used for manufacturing the panel body 10 in the embodiment. The molding apparatus 60 of the embodiment is configured as an injection molding apparatus that uses a heating and cooling method, such as heating with a heater and water cooling.

[0116] like Figure 2 As shown, the molding apparatus 60 includes an injection unit 61, a mold closing unit 62, a heating unit 63, a cooling unit 64, and a control unit 65.

[0117] The injection unit 61 includes a hopper 611, a cylinder 612, and a motor 613 for injecting resin materials such as CFRTP. The hopper 611 is the inlet for the resin material. The cylinder 612 is heated by a heater (not shown) or similar device, and the molten carbon fiber reinforced resin material is injected by the motor 613 connected to the cylinder 612.

[0118] The mold-closing unit 62 includes a mold 620 and a mold plate 625, which mold the injected carbon fiber reinforced resin material. The mold 620 has a cavity that mimics the shape of the molded article and is fitted to the movable mold plate 625. The mold 620, which is divided into multiple parts, is opened and closed by the mold plate 625, thereby molding the carbon fiber reinforced resin material filled in the cavity of the mold 620.

[0119] The heating unit 63 includes a heater 631 for heating the carbon fiber reinforced resin material within the mold 620. The heater 631 is, for example, built into the mold 620 to heat the carbon fiber reinforced resin material filling the mold cavity of the mold 620.

[0120] The cooling unit 64 includes a cooler 641, water-cooled hoses 642n and 642s, solenoid valves 643n and 643p, and air piping 644, which cool the carbon fiber reinforced resin material inside the mold 620.

[0121] Cooler 641 controls the refrigerant, such as cooling water, to a specified temperature and uses a pump (not shown) to circulate the refrigerant into mold closing unit 62 via water-cooled hoses 642n and 642s.

[0122] One end of water-cooled hoses 642n and 642s is connected to cooler 641, and the other end of water-cooled hoses 642n and 642s is connected to a flow path (not shown) provided in mold 620. Refrigerant, whose temperature is controlled by cooler 641, is supplied from water-cooled hose 642n to mold 620 and returns from water-cooled hose 642s to cooler 641.

[0123] A solenoid valve 643n is provided in the water-cooled hose 642n. During the period when the mold 620 is heated by the heater 631, the solenoid valve 643n is closed to stop the circulation of refrigerant into the mold 620.

[0124] One end of the air piping 644 is connected to a purge air supply source (not shown), and the other end is connected to a downstream portion of the water-cooled hose 642n, downstream of the solenoid valve 643n. A solenoid valve 643p is also provided on the air piping 644. This solenoid valve 643p opens as needed, thereby supplying purge air via the air piping 644 to the flow paths of the water-cooled hoses 642n, 642s, and the mold 620, and discharging refrigerant from the flow paths of the water-cooled hoses 642n, 642s, and the mold 620.

[0125] The control unit 65 includes a controller 651 and a transformer 652, and controls the entire forming device 60.

[0126] The controller 651 is configured as a computer having, for example, a CPU (Central Processing Unit), ROM (Read Only Memory), and RAM (Random Access Memory).

[0127] The controller 651 is connected to the heater 631 via cable 653h, and controls the heating temperature and heating time of the carbon fiber reinforced resin material by turning the heater 631 on / off. Additionally, the controller 651 is connected to a solenoid valve 643n located in the water-cooling hose 642n via cable 653c, and controls the cooling temperature and cooling time of the carbon fiber reinforced resin material by opening or closing the solenoid valve 643n, thereby starting or stopping the supply of refrigerant to the mold 620.

[0128] Additionally, the controller 651 is connected to a solenoid valve 643p located in the air piping 644 via a cable 653p. By opening the solenoid valve 643p, refrigerant is discharged from the water-cooled hoses 642n and 642s and the mold 620. Alternatively, the controller 651 can also be connected to the injection unit 61, the mold closing unit 62, and the cooler 641 via cables (not shown) to control these components.

[0129] Transformer 652 steps down the power supplied from a power source (not shown) on the equipment side to the operating voltage of controller 651 and supplies it to controller 651. If the power supply voltage is, for example, 380V, transformer 652 can step it down to, for example, 220V.

[0130] Next, use Figure 3 The detailed structure of mold 620 is explained.

[0131] Figure 3 This is a perspective view showing an example of the internal structure of the mold 620 used for manufacturing the panel body 10 in the embodiment. Figure 3 As shown, the mold 620 has a sprue 621, a runner 622, a gate 623 and a cavity 624 inside.

[0132] The sprue 621 is connected to a nozzle (not shown) at the top of the cylinder 612 of the injection unit 61, serving as an introduction path for the carbon fiber reinforced resin material injected from the cylinder 612. The flow channel 622 is a branching path that directs the carbon fiber reinforced resin material introduced from the sprue 621 in multiple directions. Figure 3 In this example, the flow channel 622 is arranged along one side of, for example, a frame-shaped mold cavity 624, so that the carbon fiber reinforced resin material 13 extends in the width direction of one side.

[0133] The gate 623 connects the runner 622 and the mold cavity 624, serving as the filling port for the carbon fiber reinforced resin material into the mold cavity 624. Figure 3 In this example, the gate 623 is also provided along one side of, for example, a frame-shaped mold cavity 624, so that the carbon fiber reinforced resin material flows into the mold cavity 624 from the entire width of one side. Thus, the film-shaped gate 623 connected to the runner 622 along the molded article is also referred to as, for example, a thin film gate.

[0134] The thin-film gate allows carbon fiber reinforced resin material to flow evenly into the mold cavity, and it also exhibits excellent filling properties of the carbon fiber reinforced resin material. Therefore, it is suitable for use when forming thin-walled and wide molded articles such as the frame 14 in the embodiment.

[0135] As described above, the mold cavity 624 is configured in a frame shape, mimicking, for example, the shape of a frame 14 as a molded article. It is configured to accommodate the plate-shaped member 12 within the frame of the mold cavity 624. By filling the mold cavity 624 with carbon fiber reinforced resin material while the plate-shaped member 12 is pre-accommodated within it, a frame 14 integrally formed with the plate-shaped member 12 is formed.

[0136] In this way, by configuring the mold cavity 624 to accommodate the plate-shaped member 12, it is possible to integrally form dissimilar materials such as glass, cloth, etc. constituting the plate-shaped member 12 and carbon fiber reinforced resin material constituting the frame 14.

[0137] Next, use Figures 4A to 4C To explain the details of the manufacturing method of panel 10.

[0138] Figures 4A to 4C This is an explanatory diagram illustrating an example of a manufacturing method for panel body 10.

[0139] The manufacturing method of panel body 10 includes an insertion process, a heating process, a sliding process, a filling process, and a cooling process.

[0140] Figure 4A This is an explanatory diagram of an example of an insertion process.

[0141] Specifically, mold 620 consists of mold 1 620A and mold 2 620B.

[0142] The first mold 620A has a sliding portion 620A1. The sliding portion 620A1 is configured to slide relative to the main body of the first mold 620A in both directions toward and away from the second mold 620B. During the insertion process, the sliding portion 620A1 is temporarily fixed in a state in which it slides away from the opposing second mold 620B (arrow XA direction). By temporarily fixing the sliding portion 620A1 in this position, a first recess 624A is formed in the first mold 620A. The first recess 624A constitutes a part of the mold cavity, and the depth L of the first recess 624A is pre-adjusted to be deeper than the thickness of the plate-shaped member 12 constituting the panel body 10.

[0143] One or more suction holes 620A2 are provided in the sliding part 620A1. The suction hole 620A2 is a through hole that connects the space inside the first recess 624A and the space outside the first mold 620A. It is a hole for sucking air in the first recess 624A away from the second mold 620B (arrow XA direction).

[0144] The second mold 620B is a mold having a second recess 624B arranged opposite to the first recess 624A, and together with the first mold 620A, it constitutes a mold 620. With the plate-shaped member 12 inserted into the space S formed by the first recess 624A and the second recess 624B, the first mold 620A and the second mold 620B are closed by the closing template 625, thereby the space S functions as a mold cavity 624 for forming the frame 14.

[0145] The second mold 620B is provided with a sprue 621, a runner 622, and a gate 623. Multiple sprues 621, such as sprue 621A and sprue 621B, can be provided in the second mold 620B. Additionally, multiple gates 623, such as gates 623A, gate 623B, and gate 623C, can be provided in the second mold 620B, each with a different filling location.

[0146] The structure can be as follows: Multiple gates 623 pre-installed in the mold 620 are selectively configured to function as filling ports for carbon fiber reinforced resin material through opening and closing control by a controller 651 or similar means. Alternatively, the structure can be as follows: New gates 623 are formed by sliding a portion of the mold 620 components, allowing selective configuration of a particular gate 623 as a filling port for carbon fiber reinforced resin material.

[0147] In the insertion process, with the first mold 620A and the second mold 620B separated in a direction away from each other, the plate-shaped member 12 is inserted into the space S formed by the first recess 624A of the first mold 620A and the second recess 624B of the second mold 620B. A known insertion device can be used for inserting the plate-shaped member 12. Then, using a suction mechanism, air in the first recess 624A is drawn from the suction hole 620A2 in the direction of arrow XA to the outside of the first mold 620A, thereby causing the first surface 12A of the plate-shaped member 12 to adhere to the bottom 624A1 of the first recess 624A and come into contact with it.

[0148] Next, in the heating process, with the plate-shaped member 12 held in the space S between the first mold 620A and the second mold 620B, the first mold 620A and the second mold 620B are closed using the closing template 625. This presses at least one of the first mold 620A and the second mold 620B towards each other. Then, the heating unit 63 heats the mold 620 to a temperature above the temperature at which the plate-shaped member 12 can be formed and the melting temperature of the carbon fiber reinforced resin material. By heating the mold 620, the plate-shaped member 12 held within the mold 620 is heated to this temperature, becoming shape-adjustable.

[0149] In the sliding process, the bottom 624A1 of the first recess 624A of the first mold 620A is slid toward the bottom 624B1 of the opposite second recess 624B until the second surface 12B of the plate member 12 contacts the bottom surface of the bottom 624B1.

[0150] Figure 4B This is an explanatory diagram of an example of a sliding process. The sliding process is performed with the first mold 620A and the second mold 620B closed, clamping the plate-shaped member 12 in the middle, and the molds 620 being heated by the heating process. In the sliding process, the sliding part 620A1 slides toward the bottom 624B1 of the second recess 624B in the direction of arrow XB until the second surface 12B of the plate-shaped member 12 contacts the bottom surface of the bottom 624B1 of the second recess 624B. At this time, the sliding part 620A1 presses and compresses the heated plate-shaped member 12 toward the bottom surface 624B1 with pressure to the extent that it compresses the plate-shaped member 12 between the bottom surface of the sliding part 620A1 and the bottom surface of the bottom 624B1 of the second recess 624B, thus shaping the plate-shaped member 12 into the target shape.

[0151] Therefore, even when there are deviations in the shape of multiple plate-shaped members 12 due to manufacturing conditions, storage conditions, etc., the plate-shaped members 12 can be formed into the target shape, suppressing shape deviations.

[0152] Furthermore, by adjusting the heating temperature of the heating process and the degree of pressing and compression of the plate-shaped member 12 in the sliding process according to the material of the plate-shaped member 12, the plate-shaped member 12 can be adjusted to the target shape regardless of its material.

[0153] Furthermore, as described above, the first recess 624A constitutes a part of the mold cavity, and the depth L of the first recess 624A is pre-adjusted to be deeper than the thickness of the plate member 12 that constitutes the panel body 10. Therefore, it can absorb deviations in shape such as the degree of deformation of the plate member 12 before insertion, differences in the degree of placement on the mold 620 caused by the difference in the weight of the material of the plate member 12, and deviations in the ease of fixing to the mold 620. While the plate member 12 is stably held in the first recess 624A, the plate member 12 is pressed and compressed between the bottom surfaces of the first recess 624A and the second recess 624B.

[0154] Figure 4CThis is an explanatory diagram of an example of the filling process. In the filling process, carbon fiber reinforced resin material 13 is filled into the space S between the first mold 620A and the second mold 620B, which is in a closed state as described above, into the gap between the plate member 12 and the mold 620, and into the space covering the end face of the plate member 12.

[0155] In the filling process, carbon fiber reinforced resin material 13 is filled into the space (mold cavity) through a sprue 621 (not shown) connected to a nozzle at the top of the cylinder 612 of the injection unit 61 via a runner 622 and a gate 623.

[0156] During the cooling process, heating of heating unit 63 is stopped, and cooling unit 64 is used to cool mold 620. By cooling mold 620, panel body 10 is manufactured by integrally molding dissimilar materials such as glass constituting plate member 12 and carbon fiber reinforced resin material 13 constituting frame 14.

[0157] Thus, the manufacturing method of the panel body 10 in this embodiment includes an insertion process, a heating process, a sliding process, a filling process, and a cooling process. Therefore, in the manufacturing method of the panel body 10 in this embodiment, it is possible to integrally form dissimilar materials such as glass, cloth, etc. constituting the plate-shaped member 12 and carbon fiber reinforced resin material 13 constituting the frame 14 into an insert forming process.

[0158] Furthermore, during the filling process, the carbon fiber reinforced resin material 13 can be filled in such a way that the frame 14 has anisotropy. Additionally, during the filling process, the carbon fiber reinforced resin material 13 can be filled in such a way that at least a portion of the frame 14 is colored.

[0159] As described above, the second mold 620B is provided with a sprue 621, a runner 622, and a gate 623. Multiple sprues 621, such as sprues 621A and sprues 621B, can be provided in the second mold 620B. Additionally, multiple gates 623, such as gates 623A, gate 623B, and gate 623C, can be provided in the second mold 620B, each with a different filling position. Gates 623, 623A, 623B, and 623C are examples of filling ports for the carbon fiber reinforced resin material 13. These multiple gates 623 ensure that the starting positions for the carbon fiber reinforced resin material 13 filling the aforementioned space S are different.

[0160] In the filling process, under the control of controller 651, carbon fiber reinforced resin material 13 is filled into the mold cavity through a sprue 621 and runner 622 connected to a nozzle (not shown) at the top of the cylinder 612 of injection unit 61, and flows in a direction that aligns the carbon fiber orientations to the target direction. Therefore, by selecting and switching the sprue 623 for filling the carbon fiber reinforced resin material 13 under the control of controller 651, the carbon fiber reinforced resin material 13 is filled into the mold cavity for the frame 14 in such a way that the orientation direction of the contained carbon fibers is the target direction. Thus, the frame 14 can be structured to include multiple regions containing carbon fibers in the carbon fiber reinforced resin material 13 that have different orientation directions.

[0161] Alternatively, during the filling process, carbon fiber reinforced resin materials 13 of various colors can be prepared as carbon fiber reinforced resin materials 13. Furthermore, the controller 651 can select a gate 623 for each color to fill the area to which the coloring object is to be colored, and control the filling of carbon fiber reinforced resin material 13 of that color from the gate 623.

[0162] Therefore, the frame 14 can be made into a structure containing multiple regions that are colored with different colors.

[0163] Figures 5A to 5C This is an illustrative diagram of an example of a frame 14 that is anisotropic and colored in multiple colors. Figures 5A to 5C An enlarged view of the corner of frame 14 is shown.

[0164] For example, such as Figure 5A As shown, by performing the above-described filling process, a frame 14 with multiple regions E1 and E2 having different colors and carbon fiber orientations can be formed. Furthermore, as... Figure 5B As shown, it is also possible to form a color and carbon fiber orientation direction. Figure 5A The frames 14 for different regions E3 and E4. Additionally, as... Figure 5C As shown, it is also possible to form a color and carbon fiber orientation direction. Figure 5A and Figure 5B The frames 14 for different regions E5 and E6.

[0165] The anisotropy of the frame 14 further enhances its strength. Furthermore, by adjusting the orientation of the carbon fibers in each region of the frame 14 after dividing it into multiple regions according to the application of the frame 14, the required strength of the application can be achieved, thus providing a frame 14 with the strength required by the application.

[0166] In addition, by making the frame 14 a structure that is at least partially colored, the frame 14 can have the desired appearance design.

[0167] Next, the temperature conditions of the forming apparatus 60 when the frame 14 and the plate member 12 are integrally formed will be described in detail.

[0168] Figure 6 This is a diagram showing an example of the temperature conditions of the forming apparatus 60 when the frame 14 and the plate member 12 are integrally formed according to the embodiment.

[0169] Figure 6 The horizontal axis of the graph shown represents the forming time (seconds), and the vertical axis represents the temperature of the mold at 620°C (°C). Additionally, in Figure 6 The graph shows the temperature conditions of a steam-heated molding apparatus, which is a comparative example of a molding apparatus, together with the molding apparatus 60.

[0170] like Figure 6 As shown, in the molding apparatus of the comparative example, since the temperature conditions of the mold are changed by utilizing the state change of the refrigerant between high-temperature, high-pressure water vapor and cooling water, the heating / cooling cycle requires a certain amount of time. Furthermore, because water vapor heating is used, it is difficult to heat the mold to a temperature above the melting point Tg of the resin material.

[0171] On the other hand, in the molding apparatus 60 of the embodiment, by utilizing the independent control of the heating unit 63 and the cooling unit 64, heating and cooling can be switched quickly, and the heating / cooling cycle can be shortened. In addition, since heating is performed by electrothermal means, heating control at a temperature higher than the melting point Tg of the carbon fiber reinforced resin material 13 can be achieved.

[0172] The CFRTP used in the frame 14 of the embodiment has high strength, but on the other hand, it has less deformation and is a difficult-to-form material. By heating at high temperature using an electrothermal heating method, even the difficult-to-form CFRTP can be oriented, and a thin frame 14 that matches the thin-walled plate-like member 12 as described above can be easily formed.

[0173] Furthermore, the randomization of CFRTP orientation due to high-temperature heating can suppress molding defects such as weld lines that form linear marks at the junctions of molten resin. Additionally, residual stress is reduced, thus decreasing warpage of the molded product. This further enhances the strength of the frame 14. High-gloss molding is also achieved through high-temperature heating, allowing for greater design flexibility.

[0174] Furthermore, by making the heating / cooling of the molding device 60 multi-channel, it is possible to control the temperature at different points within the mold cavity 624. This makes it easier to reduce residual stress and further reduce warpage of the molded product.

[0175] Furthermore, as described above, the CFRTP used in the frame 14 of the embodiment has a thermal shrinkage rate similar to that of the plate member 12. Therefore, when the molded article is demolded from the mold 620, damage to the plate member 12 caused by the thermal shrinkage of the frame 14 can be suppressed. Thus, as described above, even for plate members 12 with thin walls, such as 3 mm or less, 1.2 mm or more but 1.5 mm or less, or 0.8 mm or less, it is possible to integrally mold them with the frame 14.

[0176] (Summary)

[0177] With the increasing size of display devices, the transportation and assembly of plate-shaped components 12, such as glass, have become more difficult. In addition, the number of various display devices installed in vehicles, such as monitors for navigation systems, is also increasing.

[0178] When the display device is used as an in-vehicle device, when the display device is installed in a vehicle, there may be slight twisting at the diagonal of the plate-shaped member 12 such as glass due to vehicle brackets, other interior components, etc. In this case, there is a concern that the plate-shaped member 12 may break instantly or break over time.

[0179] On the other hand, display devices used as in-vehicle equipment are also required to meet collision safety standards such as the U.S. Federal Motor Vehicle Safety Standards, and regulations for interior fittings in Japan and Europe.

[0180] Therefore, techniques exist for increasing the strength of glass components by attaching stamped or die-cast metal parts. In recent years, lightweight and high-strength magnesium die-cast parts, for example, have attracted attention. However, the manufacturing cycle time for metal components such as magnesium is long, limiting production quantities. Furthermore, the extensive use of deburring and other finishing processes also presents a costly challenge.

[0181] According to the embodiment, the panel body 10 includes a plate-shaped member 12 and a CFRTP frame 14 integrally formed with the plate-shaped member 12, the frame 14 seamlessly covering the end face of the plate-shaped member 12.

[0182] In this way, by integrally molding the CFRTP frame 14 into the plate member 12, a high-strength panel body 10 can be obtained. Furthermore, the overall torsional stiffness of the plate member 12 can be improved. Therefore, cracking and damage to the plate member 12 can be suppressed, and processing becomes easier.

[0183] Furthermore, since the frame 14 seamlessly covers the end face of the plate member 12, the panel body 10 can have an appearance design, and can be directly applied to a display device without surface coating.

[0184] Furthermore, by using a CFRTP frame 14 instead of metal components such as magnesium die castings, it is possible to achieve further weight reduction while maintaining strength.

[0185] In addition, by using CFRTP with thermal shrinkage properties similar to those of the plate member 12 in the frame 14, damage to the plate member 12 caused by thermal shrinkage of the frame 14 can be suppressed when demolding from the mold 620.

[0186] According to the embodiment of the panel body 10, the frame body 14 is configured to clamp the plate-shaped member 12 from the front and back sides. That is, the frame body 14 has a first pressing portion 14A extending from the end face of the plate-shaped member 12 towards the first surface 12A and surrounding the edge of the first surface 12A in a frame shape, and a second pressing portion 14B extending from the end face of the plate-shaped member 12 towards the second surface 12B and surrounding the edge of the second surface 12B in a frame shape.

[0187] In this way, the first pressing portion 14A of the first surface 12A of the plate-shaped member 12 can more reliably protect the end face of the plate-shaped member 12, further improving the strength of the panel body 10. Furthermore, by holding the plate-shaped member 12 from both the surface and back sides by the frame 14, the strength of the plate-shaped member 12 can be uniformly improved. Therefore, even if the plate-shaped member 12, made of glass or the like, breaks due to impact or collision, it is less likely to shatter. This is because, generally, glass shattering is caused by uneven strength.

[0188] According to the embodiment of the panel body 10, the thickness of the plate-shaped member 12 is 3 mm or less, 1.2 mm or more but 1.5 mm or less, or 0.8 mm or less. By providing the frame 14 as described above on the plate-shaped member 12, even with such a thin-walled plate-shaped member 12, cracking and defects can be suppressed, and processing becomes easier. In addition, it is possible to suppress the plate-shaped member 12 from breaking due to the thermal shrinkage of the frame 14 during demolding.

[0189] According to the manufacturing method of the panel body 10 in the embodiment, the frame body 14 is formed by heating and cooling at a temperature exceeding the melting point Tg. Furthermore, a thin-film gate is used for the gate 623 of the mold 620.

[0190] Therefore, the frame 14 can be formed using CFRTP, a difficult-to-form material. Furthermore, the orientation of the CFRTP can be controlled to form a thin frame 14. Additionally, the random orientation of the CFRTP can suppress forming defects such as weld lines, further improving the strength of the frame 14. Furthermore, residual stress can be reduced, thus decreasing the warpage of the frame 14. This allows for thinning of the plate-like member 12. Additionally, the surface of the frame 14 can be made highly glossy, enhancing its aesthetic appeal.

[0191] (Variation Example 1)

[0192] Next, use Figures 7A to 8C The panel bodies 2 and 3 of the modified embodiment 1 will now be described. The panel bodies 2 and 3 of the modified embodiment 1 differ from the panel body 10 of the above-described embodiment in that they possess curved plate-like members 210 and 310. Furthermore, in the following... Figures 7A to 8C In this document, the same reference numerals are used to refer to the same structures as those in the panel body 10 of the above-described embodiment, and their descriptions are omitted.

[0193] Figures 7A to 7C This is a schematic diagram showing an example of the structure of the panel body 2 of a modified embodiment 1. Figure 7A This is a perspective view of panel 2 as seen from the first side. Figure 7B This is a perspective view of panel 2 as seen from the second side. Figure 7C This is a top view of panel 2.

[0194] like Figures 7A to 7C As shown, panel body 2 has plate-shaped member 210 and frame 220.

[0195] The plate-shaped member 210 is a rectangular optical glass with a curved surface. The curved surface of the plate-shaped member 210 can have, for example, a generally uniform curvature. In this case, Figures 7A to 7C In the example, the first surface 211 of the plate-like member 210 is a convex surface, and the second surface 212 of the plate-like member 210 is a concave surface. Furthermore, Figures 7A to 7C An example is shown where the curvature of the plate member 210 is relatively small.

[0196] The frame 220 is a CFRTP resin component integrally formed with the plate member 210, seamlessly covering the end face of the plate member 210. Furthermore, the frame 220 is configured to clamp the plate member 210 from its surface and back, and has a frame-shaped first pressing portion 221 extending from the end face of the plate member 210 towards the first surface 211, and a frame-shaped second pressing portion 222 extending from the end face of the plate member 210 towards the second surface 212.

[0197] The first pressing part 221 surrounds the edge of the first surface 211 of the plate member 210 in a frame-like manner. It may be that the width extending in the direction of the center of the plate member 210 is shorter than that of the second pressing part 222, which surrounds the edge of the second surface 212 of the plate member 210 in a frame-like manner.

[0198] Figures 8A to 8C This is a schematic diagram illustrating another example of the structure of panel body 3, which is a modified example of the embodiment. Figure 8A This is a perspective view of panel 3 as seen from the first side. Figure 8B This is a perspective view of panel 3 as seen from the second side. Figure 8C This is a top view of panel 3.

[0199] like Figures 8A to 8C As shown, panel body 3 has plate-shaped member 310 and frame 320.

[0200] The plate-shaped member 310 is a rectangular optical glass with a curved surface. The curved surface of the plate-shaped member 310 can have, for example, a generally uniform curvature. In this case, Figures 8A to 8C In the example, the first surface 311 of the plate member 310 is a convex surface, and the second surface 312 of the plate member 310 is a concave surface. Furthermore, Figures 8A to 8C An example of a plate-shaped member 310 with a relatively large curvature is shown.

[0201] The frame 320 is a CFRTP resin component integrally formed with the plate member 310, seamlessly covering the end face of the plate member 310. Furthermore, the frame 320 is configured to clamp the plate member 310 from its surface and back side, and has a pressing portion 321 as a frame-shaped first pressing portion extending from the end face of the plate member 310 towards the first surface 311, and a pressing portion 322 as a frame-shaped second pressing portion extending from the end face of the plate member 310 towards the second surface 312.

[0202] The pressing part 321 surrounds the edge of the first surface 311 of the plate member 310 in a frame-like manner. It may be that the width extending towards the center of the plate member 310 is shorter than that of the pressing part 322, which surrounds the edge of the second surface 312 of the plate member 310 in a frame-like manner.

[0203] When the frame 220 and 320 are integrally formed from plate-shaped members 210 and 310 with such curved surfaces, it can be addressed by using a mold capable of accommodating curved glass.

[0204] As mentioned above, the demand for display devices for various applications, such as automotive, has been increasing in recent years. Furthermore, it is foreseeable that the practical application of organic EL (Elastic Optical Cell) will generate expectations for designs using curved glass. It is believed that because glass has a curved surface, issues such as the handling of glass components during transportation, assembly, and installation in vehicles, as well as the suppression of torsion during assembly and installation, will become more complex.

[0205] According to the panel bodies 2 and 3 of Modified Example 1, the plate-shaped members 210 and 310 have curved surfaces. As described above, the plate-shaped members 210 and 310 with such curved surfaces can be applied to the panel bodies 2 and 3 by integrally forming them with the frames 220 and 320.

[0206] In addition, the panel bodies 2 and 3 according to Modified Example 1 have the same effect as the panel body 10 of the above-described embodiment.

[0207] (Variation Example 2)

[0208] Next, use Figures 9A to 10D The panel bodies 4 and 5 of the modified embodiment 2 will now be described. The panel bodies 4 and 5 of the modified embodiment 2 differ from the panel body 10 of the above-described embodiment in that the plate-shaped members 410 and 510 are curved glass. Furthermore, in the following... Figures 9A to 10D In this document, the same reference numerals are used to refer to the same structures as those in the panel body 10 of the above-described embodiment, and their descriptions are omitted.

[0209] Figures 9A to 9D This is a schematic diagram illustrating an example of the structure of panel body 4 in modified embodiment 2. Figure 9A This is a perspective view of panel 4 as seen from the first side. Figure 9B This is a perspective view of panel 4 as seen from the second side. Figure 9C This is a top view of panel 4. Figure 9D This is an enlarged sectional view of the bent portion 413 of the plate-shaped member 410.

[0210] like Figures 9A to 9D As shown, panel body 4 has plate-shaped member 410 and frame body 420.

[0211] The plate-shaped member 410 is a curved glass formed by bending a generally flat rectangular optical glass in multiple parts. That is, the plate-shaped member 410 has a plate-shaped portion 410a as a first surface, a plate-shaped portion 410b as a second surface adjacent to the plate-shaped portion 410a at one end, and a plate-shaped portion 410c as a third surface adjacent to the plate-shaped portion 410a at the opposite end to the plate-shaped portion 410b.

[0212] Plate-shaped portions 410a and 410b are connected at a predetermined angle by a curved portion 413, which serves as a first curved portion. Plate-shaped portions 410a and 410c are connected at a predetermined angle by a curved portion 414, which serves as a second curved portion. At this time, in... Figures 9A to 9D In the example, the first surface 411 of the plate member 410 becomes the valley side of the curved portions 413 and 414, and the second surface 412 of the plate member 410 becomes the mountain side of the curved portions 413 and 414.

[0213] also, Figures 9A to 9D Examples are shown where the bending angles of the bends 413 and 414 are obtuse. Figures 9A to 9D In the example, the angle between plate-shaped portions 410a and 410b, and the angle between plate-shaped portions 410a and 410c, are, for example, 135°. However, these angles may also be different from each other.

[0214] Such curved portions 413 and 414 are composed of minute curved surfaces. That is, by having minute curved surfaces in the curved portions 413 and 414, the plate-shaped portions 410a to 410c are connected at a predetermined angle. In this case, the local curvature at the curved portions 413 and 414 is greater than the curvature of the plate-shaped members 210 and 310 of the above-described modified example 1, which are curved as a whole.

[0215] like Figure 9D As shown, if the curvature at the bend 413 is expressed as the distance from the bend position of the plate member 410 to the center point of the bend, i.e., the bend radius (bend R), then the bend R of the plate member 410 at the bend 413 can be, for example, 5 mm or less.

[0216] In addition, Figures 9A to 9D In the example, plate-shaped portions 410b and 410c are of equal size, while plate-shaped portion 410a is smaller than these plate-shaped portions 410b and 410c. However, the dimensions of these plate-shaped portions 410a to 410c can be varied according to the appearance design of the display device to be assembled.

[0217] The frame 420 is a CFRTP resin component integrally formed with the plate-shaped member 410, seamlessly covering the end face of the plate-shaped member 410. Furthermore, the frame 420 is configured to clamp the plate-shaped member 410 from its surface and back side, and has a pressing portion 421 as a frame-shaped first pressing portion extending from the end face of the plate-shaped member 410 towards the first surface 411, and a pressing portion 422 as a frame-shaped second pressing portion extending from the end face of the plate-shaped member 410 towards the second surface 412.

[0218] The pressing portion 421 surrounds the edge of the first surface 411 of the plate member 410 in a frame-like manner. It may extend longer toward the center of the plate member 410 compared to the pressing portion 422 that surrounds the edge of the second surface 412 of the plate member 410 in a frame-like manner.

[0219] Figures 10A to 10D This is a schematic diagram illustrating another example of the structure of the panel body 5 of the modified embodiment 2. Figure 10A This is a perspective view of panel 5 as seen from the first side view. Figure 10B This is a perspective view of panel 5 as seen from the second side. Figure 10C This is a top view of panel 5. Figure 10D This is an enlarged sectional view of the bent portion 513 of the plate-shaped member 510.

[0220] like Figures 10A to 10D As shown, panel body 5 has plate-shaped member 510 and frame body 520.

[0221] The plate member 510 is a curved glass formed by bending a generally flat rectangular optical glass at one point. That is, the plate member 510 has a plate portion 510a as a first surface and a plate portion 510b as a second surface adjacent to the plate portion 510a at one end.

[0222] Plate-shaped portions 510a and 510b are connected at a predetermined angle by a curved portion 513, which serves as a first curved portion. At this time, Figures 10A to 10D In the example, the first surface 511 of the plate member 510 becomes the valley side of the bend 513, and the second surface 512 of the plate member 510 becomes the mountain side of the bend 513.

[0223] also, Figures 10A to 10D An example is shown where the bending angle of the bend 513 is a smaller angle. Figures 10A to 10D In the example, the angle between the plate-shaped portion 510a and the plate-shaped portion 510b is, for example, 92°. Thus, the frame 520 can also be applied to curved glass with an angle close to a right angle, for example, less than 95°.

[0224] Such a curved portion 513 is also composed of a small curved surface. That is, by having a small curved surface in the curved portion 513, the plate-shaped portions 510a and 510b are connected at a predetermined angle. In this case, the local curvature at the curved portion 513 is further increased compared to the curvature of the curved portions 413 and 414 of the plate-shaped member 410 described above.

[0225] like Figure 10D As shown, if the curvature at the bend 513 is expressed as the aforementioned bending radius (bending R), then when the bending angle of the plate member 510 is less than 95°, the bending R can be, for example, less than 1.5 mm. Figure 10D In the example, when the bending angle of the plate member 510 is 92°, the bending radius R can be, for example, 1 mm.

[0226] The frame 520 is a CFRTP resin component integrally formed with the plate-shaped member 510, seamlessly covering the end face of the plate-shaped member 510. Furthermore, the frame 520 is configured to clamp the plate-shaped member 510 from its surface and back side, and has a pressing portion 521 as a frame-shaped first pressing portion extending from the end face of the plate-shaped member 510 towards the first surface 511, and a pressing portion 522 as a frame-shaped second pressing portion extending from the end face of the plate-shaped member 510 towards the second surface 512.

[0227] The pressing portion 521 surrounds the edge of the first surface 511 of the plate member 510 in a frame-like manner. It may extend longer toward the center of the plate member 510 compared to the pressing portion 522 that surrounds the edge of the second surface 512 of the plate member 510 in a frame-like manner.

[0228] When the frame 420 and 520 are integrally formed from plate-shaped members 410 and 510 having the above-mentioned curved portions 413, 414 and 513, the problem can be solved by using a mold capable of accommodating curved glass.

[0229] It is foreseeable that the practical application of organic EL will also generate expectations for the use of curved glass in display devices. Undeniably, the use of curved glass in display devices will further complicate issues such as the transportation, assembly, and installation of glass components in vehicles, as well as the suppression of torsion during assembly and installation.

[0230] According to the panel body 5 of Modified Example 2, the plate-shaped member 510 has a plate-shaped portion 510a, a plate-shaped portion 510b adjacent to the plate-shaped portion 510a at one end, and a curved portion 513 connecting the plate-shaped portion 510a and the plate-shaped portion 510b at a predetermined angle. As described above, the plate-shaped member 510 having such a curved portion 513 can be applied to the panel body 5 by integrally forming it with the frame body 520.

[0231] According to the panel body 5 of Modified Example 2, the angle between the plate-shaped portion 510a and the plate-shaped portion 510b is less than 95°. In this way, even for curved glass with an angle close to a right angle, the frame body 520 can be integrally formed with the curved glass in accordance with the curved glass.

[0232] According to the panel body 4 of Modified Example 2, in addition to the plate-shaped portions 410a, 410b and the curved portion 413, the plate-shaped member 410 also includes a plate-shaped portion 410c adjacent to the plate-shaped portion 410a on the opposite end to the plate-shaped portion 410b, and a curved portion 414 connecting the plate-shaped portions 410a and 410c at a predetermined angle. In this way, even for curved glass with a complex shape that bends on both sides, the frame 420 can be integrally formed with the curved glass in accordance with the curved glass.

[0233] In addition, the panel bodies 4 and 5 according to Modified Example 2 have the same effect as the panel body 10 of the above-described embodiment.

[0234] Furthermore, in the above-described embodiments and variations 1 and 2, the frames 14, 220, and 520 that surround the end faces of the plate-shaped members 12, 210 to 510 in a frame-like manner were described. However, the frame provided with the panel body may also have, for example, a shape that extends partially together with the frame-shaped portion surrounding the end faces of the plate-shaped members, thereby constituting part of the appearance design of the second panel and housing of the display device at the assembly destination.

[0235] Furthermore, in the above-described embodiments and variations 1 and 2, examples of panel bodies 10, 2 to 5 having generally rectangular plate-shaped members 12, 210 to 510 were given for illustration. However, the plate-shaped members used for the panel body may also be shapes other than rectangles, such as circles, ellipses, or other polygons.

[0236] (Second Implementation)

[0237] Next, a display device having panel bodies 10, 2 to 5 as described in the above embodiments and variations will be described. Furthermore, in this embodiment, the display device is described as having a structure having panel body 10. However, the display device may also have a structure having any of panel bodies 2 to 5.

[0238] Figure 11 and Figure 12 This is a schematic diagram illustrating an example of the display device 100 in this embodiment. Figure 11 This is a schematic diagram showing an example of the overall structure of the display device 100. Figure 12 This is a schematic diagram showing the display device 100 broken down into its constituent parts.

[0239] Display device 100 is a display device that displays various information.

[0240] The display device 100 includes a panel body 10, a holder body 20, a liquid crystal panel 30, and a main body 40.

[0241] The panel body 10 is a component provided on the panel portion of the display device 100. The panel body 10 includes a plate-shaped member 12 and a frame 14. The plate-shaped member 12 provided on the display device 100 is a plate-shaped glass made of glass.

[0242] The retainer 20 is a component that holds the panel body 10. The retainer 20 is, for example, a decorative frame. The decorative frame is a component used to hold or cover the panel body 10 for protection.

[0243] The liquid crystal panel 30 is a display that shows various images. The liquid crystal panel 30 is, for example, a liquid crystal display, an organic EL (Electro-Luminescence) display, etc.

[0244] The main body 40 includes control units for controlling the various parts of the display device 100.

[0245] The display device 100 is manufactured, for example, by assembling a holder 20, on which a panel body 10 and a liquid crystal panel 30 are assembled, onto a main body 40.

[0246] As described above, the display device 100 of this embodiment includes a panel body 10. The panel body 10 has a plate-shaped member 12 and a CFRTP frame 14 integrally formed with the plate-shaped member 12 and seamlessly covering the end face of the plate-shaped member 12.

[0247] In recent years, with the increasing size of display devices, the transportation and assembly of the plate-shaped component 12 have become more difficult. In addition, the number of plate-shaped components 12 mounted on various display devices 100, such as monitors for vehicle navigation systems, is increasing.

[0248] As described above, when the display device is used as an in-vehicle device, slight twisting may sometimes occur diagonally in the plate member 12 due to vehicle brackets, other interior components, etc. In this case, there is a concern that the glass may break instantly or break over time.

[0249] On the other hand, display devices used as in-vehicle equipment are also required to meet collision safety standards such as the U.S. Federal Automotive Safety Standards and passenger compartment protrusion limits in Japan and Europe.

[0250] Therefore, techniques exist for increasing the strength of glass components by attaching stamped or die-cast metal parts. In recent years, lightweight and high-strength magnesium die-cast parts, for example, have attracted attention. However, the manufacturing cycle time for metal components such as magnesium is long, limiting production quantities. Furthermore, the extensive use of deburring and other finishing processes also presents a costly challenge.

[0251] Furthermore, structures have been disclosed that include protective components such as buffers and protective members to prevent breakage of glass parts. Structures have also been disclosed that include metal components such as stamped parts and castings to improve product strength. Additionally, as a countermeasure against unforeseen circumstances, measures such as attaching a protective film to the glass surface to prevent scattering have been implemented. However, in such structures, the number of components in the display device increases, sometimes complicating the device structure. Therefore, in conventional display devices, difficulties sometimes arise in handling breakage and increasing device complexity.

[0252] On the other hand, the display device 100 of this embodiment includes a panel body 10 and a retainer body 20. The panel body 10 has a plate-shaped member 12 and a frame 14 made of carbon fiber reinforced resin that is integrally formed with the plate-shaped member 12 and seamlessly covers the end face of the plate-shaped member 12.

[0253] In this way, by constructing the panel body 10 from the plate-shaped member 12 and the frame 14 made of carbon fiber reinforced resin integrally formed with the plate-shaped member 12 and seamlessly covering the end face of the plate-shaped member 12, it is possible to achieve high strength of the panel body 10 and improve the overall torsional stiffness of the plate-shaped member 12.

[0254] In detail, by integrally forming a frame 14 around the plate-like member 12, the overall torsional stiffness of the panel body 10 is improved. This suppresses torsion at the diagonals of, for example, a rectangular plate-like member 12, thus preventing breakage of the plate-like member 12. Furthermore, since the end faces of the plate-like member 12 are protected by the frame 14, breakage such as cracks and defects at the end faces of the plate-like member 12 can be suppressed. In addition, the overall strength of the plate-like member 12 against impacts and collisions is improved.

[0255] Furthermore, since the overall torsional stiffness of the panel body 10 is increased, the assembly of the panel body 10 to the holder 20 during manufacturing becomes easier. In addition, since the overall torsional stiffness of the panel body 10 can be increased and the breakage of the plate member 12 can be suppressed, it is possible to prevent breakage such as cracking or damage to the plate member 12 during transportation, assembly of the panel body 10 to the holder 20 during manufacturing, and installation on vehicles, etc.

[0256] Furthermore, even when the structure is designed to omit at least one of the following components: a buffer, a protective member, a metal part for improving the strength of the product, and a protective film for preventing scattering, the strength of the plate member 12 can still be improved, and the complexity of the device structure can be suppressed.

[0257] Therefore, in the display device 100 of this embodiment, the handling during transportation and assembly becomes easier.

[0258] Therefore, this embodiment can provide a display device 100 that is easy to process.

[0259] Furthermore, the display device 100 of this embodiment can suppress the breakage of the plate-shaped member 12 without adding protective members or the like for suppressing breakage. Therefore, in addition to the effects described above, the display device 100 of this embodiment can also simplify the device structure and manufacturing process.

[0260] Furthermore, the display device 100 of this embodiment can be configured to have a panel body 10 with a frame 14 made of CFRTP instead of metal parts such as die-cast magnesium. Therefore, in addition to the effects described above, the display device 100 of this embodiment can also achieve a lighter weight while maintaining the strength of the panel body 10.

[0261] Furthermore, in this embodiment, the frame 14 of the display device 100 seamlessly covers the end face of the plate-shaped member 12, thus enabling the panel body 10 to have an aesthetic design. For example, the frame 14 of this embodiment can be directly applied to the display device 100 without surface coating or the like.

[0262] (Third Implementation)

[0263] In this embodiment, the frame 14 in the above embodiment is described as having an assembly section. The assembly section refers to the part used for assembling with other components constituting the display device 100.

[0264] Figure 13A and Figure 13B This is an explanatory diagram of an example of the display device 101 according to this embodiment. The display device 101 has the same structure as the display device 100 of the above embodiment, except that the frame 15, which corresponds to the frame 14 of the display device 100 of the above embodiment, also has an assembly portion, and the holder 21, which corresponds to the holder 20, also has an assembly portion. For structures identical to those in the above embodiment, the same reference numerals are used, and detailed descriptions are omitted.

[0265] Figure 13A and Figure 13B This is a schematic diagram of an example of the display device 101A according to this embodiment. The display device 101A is an example of the display device 101. Figure 13A This is a perspective view of display device 101A. Figure 13B This is an enlarged view of a portion (area A) of the display device 101A.

[0266] like Figure 13A As shown, the display device 101A includes a panel body 11, a holding body 21, a liquid crystal panel 30, and a main body 40. The liquid crystal panel 30 and the main body 40 are the same as in the embodiment described above, so they are omitted from the illustration.

[0267] The panel body 11 is the same as the panel body 10 in the above embodiment, except that it has a frame body 15 with an assembly part 14C instead of a frame body 14. The frame body 15 is the same as the frame body 14 in the above embodiment, except that it has an assembly part 14C. That is, like the frame body 14, the frame body 15 is a CFRTP frame that is integrally formed with the plate-shaped member 12 and seamlessly covers the end face of the plate-shaped member 12.

[0268] Assembly part 14C is a partial part of frame 15, used for positioning and fixing during assembly with retainer 21. Assembly part 14C is integrally formed with frame body 14Z of frame 15. Frame body 14Z is a frame-shaped part of frame 15 that seamlessly covers the end face of plate member 12 and follows the shape of the outer periphery of plate member 12. Assembly part 14C engages or fits with assembled part 20C provided on retainer 21.

[0269] Except for the fact that it has the assembly part 20C, the retainer 21 is the same as the retainer 20 in the above embodiment. The assembly part 20C is a part of the retainer 21 that engages or fits with the assembly part 14C of the frame 15.

[0270] like Figure 13A As shown, one or more assembly parts 14C1 are provided on the frame 15 of the panel body 11. Assembly part 14C1 is an example of assembly part 14C. Additionally, as... Figure 13A As shown, one or more assembled parts 20C1 are provided in the holding body 21. The assembled part 20C1 is an example of the assembled part 20C.

[0271] exist Figure 13A As an example, a structure is shown in which four assembly parts 14C1 are respectively provided on the four sides of the outer perimeter of the rectangular frame 15. Furthermore, in Figure 13A As an example, a structure is shown in which four assembly parts 20C1 are respectively provided on the four sides of the outer periphery of the opening P provided in the holding body 21. The opening P is an opening provided in the holding body 21, which is the area for assembling the panel body 11.

[0272] The positions of the assembly part 14C1 and the assembled part 20C1 are only required to be mutually engaged, and are not limited to specific locations. Figure 13A The method shown. Furthermore, the number of assembly parts 14C and assembled parts 20C is not limited to the number of at least one pair of assembly parts 14C1 and assembled parts 20C1 engaging. Figure 13A As shown in the diagram.

[0273] like Figure 13BAs shown, the assembly part 20C1 of the retainer 21 and the assembly part 14C1 of the panel body 11 are engaged when the panel body 11 and the retainer 21 are assembled in the correct position.

[0274] For example, such as Figure 13B As shown, the assembly part 14C1 protrudes outward from the rectangular frame body 14Z and toward the side of the frame 15, forming a claw shape that, after assembly, is locked onto the assembly part 20C1 in a fixed state. Furthermore, the assembly part 20C1 is provided on the outer peripheral surface of the holder 21 facing the rectangular opening P for assembling the panel body 11, and is recessed in a direction away from the opening P. Additionally, the assembly part 20C1 is in a locked state where the assembly part 14C1 is locked in place when the panel body 11 is assembled. That is, the convex assembly part 14C1 and the recessed assembly part 20C1 are engaged.

[0275] As explained above, in the display device 101A of this embodiment, the frame 15 has an assembly portion 14C1 that is assembled to the retainer 21. Furthermore, the retainer 21 has an assembly portion 20C1 that engages with the assembly portion 14C1.

[0276] Therefore, when assembling the panel body 11 to the holder 21, the panel body 11 can be easily and correctly assembled to the holder 21 by engaging the assembly part 14C1 of the frame body 15 with the assembly part 20C1 of the holder 21.

[0277] Therefore, in addition to the effects of the above-described embodiments, the display device 101A of this embodiment can also be a structure that facilitates the assembly of the panel body 11 to the holder 21.

[0278] Furthermore, in the display device 101A of this embodiment, the user can assemble the panel body 11 to the retainer 21 by engaging the assembly part 14C1 of the frame 15 with the assembly part 20C1 of the retainer 21. Therefore, in addition to the effects described above, the display device 101A of this embodiment does not require additional user manuals, double-sided tape, adhesive, screws, or other components for assembly, and the panel body 11 can be easily and correctly fixed and assembled to the retainer 21.

[0279] Furthermore, the assembly part 14C1 and the assembled part 20C1 are positioned and shaped to engage when the panel body 11 and the retainer 21 are assembled in the correct positions. Therefore, in addition to the effects described above, the display device 101A of this embodiment can also help reduce and simplify the positioning work when assembling the panel body 11 into the retainer 21.

[0280] Furthermore, in the display device 101A of this embodiment, the assembly part 14C1 is integrally formed with the frame body 14Z of the frame 15. Also, in the display device 101A of this embodiment, the frame body 14Z and the assembly part 14C1 of the frame 15, like the frame 14 of the above embodiment, seamlessly cover the end face of the plate-shaped member 12 and are made of CFRTP. Therefore, this embodiment can provide a display device 101A that, in addition to the effects of the above embodiments, also suppresses damage to the plate-shaped member 12 and facilitates assembly.

[0281] (Variation Example 3)

[0282] In the above embodiment, the assembly part 14C is described as protruding outward from the rectangular frame body 14Z and toward the side of the frame 15. In another embodiment, the assembly part 20C is described as being recessed on the outer peripheral surface of the retainer 21 facing the opening P, and recessed toward the side away from the opening P.

[0283] However, the assembly part 14C and the assembled part 20C can be any structure that interlocks or fits into each other, and the protruding direction or recessed direction and shape are not limited to the above embodiments.

[0284] For example, assembly part 14C and assembled part 20C can also be Figure 14A and Figure 14B The structure shown.

[0285] Figure 14A and Figure 14B This is an explanatory diagram of an example of the display device 101B in this modified example. The display device 101B is an example of the display device 101. Figure 14A This is a perspective view of display device 101B. Figure 14B This is an enlarged view of a portion (region B) of the display device 101B. For structures identical to those described in the above embodiments and variations, the same reference numerals are used, and detailed descriptions are omitted.

[0286] In this modified example, the frame 15 of the panel body 11 has an assembly part 14C2 instead of an assembly part 14C1. Furthermore, the retainer 21 in this modified example has an assembly part 20C2 instead of an assembly part 20C1. The assembly part 14C2 is an example of the assembly part 14C, and the assembly part 20C2 is an example of the assembly part 20C.

[0287] exist Figure 14A As an example, a structure is shown in which three assembly parts 14C2 are respectively provided on two parallel sides of the four sides of the outer perimeter of the rectangular frame 15. Furthermore, in Figure 14AAs an example, a structure is shown in which three assembly parts 20C2 are respectively provided on two parallel sides of the four sides constituting the outer periphery of the opening P of the retaining body 21. The positions and numbers of the assembly parts 14C2 and the assembly parts 20C2 are not limited as long as they are mutually engaging. Figure 14A As shown in the diagram.

[0288] like Figure 14B As shown, the assembly part 20C2 of the retainer 21 and the assembly part 14C2 of the panel body 11 are engaged in the correct position and shape.

[0289] For example, such as Figure 14B As shown, the assembly part 14C2 protrudes from the rectangular frame body 14Z toward the retainer 21 and, after assembly, forms a claw-shaped locking state that is fixed to the assembly part 20C2. The assembly part 20C2 is provided on the opposite surface of the retainer 21 opposite to the panel body 11 and is a recessed shape formed in a direction away from the panel body 11. Furthermore, the assembly part 20C2 is in a locking state that is fixed by locking the assembly part 14C2 when the panel body 11 is assembled. That is, the convex assembly part 14C2 and the concave assembly part 20C2 are configured to engage.

[0290] Thus, as long as the assembly part 14C2 of the frame 15 and the assembly part 20C2 of the retainer 21 are interlocking structures, one can be convex and the other concave along the installation direction. With such a shape, the same effect as in the second embodiment described above can be obtained.

[0291] (Variation Example 4)

[0292] In this modified example, an assembly part 14C and an assembly part 20C with shapes different from those in the second embodiment and the modified example described above are explained.

[0293] Figure 15A and Figure 15B This is an explanatory diagram of an example of the display device 101C in this modified example. The display device 101C is an example of the display device 101. Figure 15A This is a perspective view of display device 101C. Figure 15B This is an enlarged view of a portion (region C) of the display device 101C. For structures identical to those described in the above embodiments and variations, the same reference numerals are used, and detailed descriptions are omitted.

[0294] In this modified example, the frame 15 of the panel body 11 has an assembly part 14C3 instead of an assembly part 14C1. Furthermore, the retainer 21 in this modified example has an assembly part 20C3 instead of an assembly part 20C1. The assembly part 14C3 is an example of the assembly part 14C, and the assembly part 20C3 is an example of the assembly part 20C.

[0295] exist Figure 15A As an example, a structure is shown in which an assembly part 14C3 is provided at two of the four vertices formed by the four sides constituting the outer periphery of the rectangular frame 15. Additionally, in Figure 15A As an example, a structure is shown in which an assembled part 20C3 is provided at two of the four vertices formed by the four sides constituting the outer periphery of the opening P of the retaining body 21, respectively, at positions opposite to the assembly part 14C3 during assembly. The positions and numbers of the assembly part 14C3 and the assembled parts 20C3 are not limited to any positions and numbers that interlock with each other. Figure 15A As shown in the diagram.

[0296] like Figure 15B As shown, the assembly part 20C3 of the retainer 21 and the assembly part 14C3 of the panel body 11 are the positions and shapes in which they fit together when the panel body 11 and the retainer 21 are assembled in the correct positions.

[0297] For example, such as Figure 15B As shown, the assembly part 14C3 protrudes from the rectangular frame body 14Z toward the retainer 21, and after assembly, forms a fitted state with the assembled part 20C3. Figure 15B As an example, the assembly part 14C3 is shown as a cylindrical region that protrudes from the frame body 14Z toward the retainer 21.

[0298] The assembled portion 20C3 is provided on the opposing surface of the retainer 21 opposite to the panel body 11, and is a recessed shape formed in a direction away from the panel body 11. Furthermore, the assembled portion 20C3 is in a fitted state where it is engaged with the assembled portion 14C3 when the panel body 11 is assembled. That is, the convex assembled portion 14C3 and the recessed assembled portion 20C3 are fitted together. In other words, the outer peripheral surfaces of the assembled portion 14C3 and the assembled portion 20C3 are in a shape where they abut against each other and their outer peripheral surfaces are smoothly continuous when the panel body 11 is assembled to the retainer 21.

[0299] Thus, the assembly portion 14C3 of the frame 15 and the assembled portion 20C3 of the retainer 21 can also be a mutually fitting structure. For example, the assembly portion 14C3 and the assembled portion 20C3 can be one convex and the other concave. With such shapes, the same effect as in the second embodiment described above can be obtained.

[0300] (Variation Example 5)

[0301] In this modified example, an assembly part 14C and an assembly part 20C with shapes different from those in the second embodiment and the modified example described above are explained.

[0302] Figure 16A and Figure 16B This is an explanatory diagram of an example of the display device 101D in this modified example. The display device 101D is an example of the display device 101. Figure 16A This is a 3D view of the display device 101D. Figure 16B This is an enlarged view of a portion (region D) of the display device 101D. For structures identical to those described in the above embodiments and variations, the same reference numerals are used, and detailed descriptions are omitted.

[0303] In this modified example, the frame 15 of the panel body 11 has an assembly part 14C4 instead of the assembly part 14C1. Furthermore, the retainer 21 in this modified example has an assembly part 20C4 instead of the assembly part 20C1. The assembly part 14C4 is an example of the assembly part 14C, and the assembly part 20C4 is an example of the assembly part 20C.

[0304] exist Figure 16A As an example, a structure is shown in which an assembly part 14C4 is provided at each of the two ends along the length of one of the four sides of the outer perimeter of the rectangular frame 15. Additionally, in Figure 16A As an example, a structure is shown in which assembled parts 20C4 are provided at positions opposite to each assembled part 14C4 on the four sides of the outer periphery of the opening P of the retaining body 21, opposite to the side of the panel body 11 where the assembled parts 14C4 are provided. The positions and numbers of the assembled parts 14C4 and the assembled parts 20C4 are not limited as long as they are mutually interlocking. Figure 16A As shown in the diagram.

[0305] like Figure 16B As shown, the assembly part 20C4 of the retainer 21 and the assembly part 14C4 of the panel body 11 are the positions and shapes in which they fit together when the panel body 11 and the retainer 21 are assembled in the correct positions.

[0306] For example, such as Figure 16B As shown, the assembly part 14C4 is located on the outer peripheral surface of the rectangular frame body 14Z, and is a convex shape protruding in a direction away from the outer peripheral surface. Figure 16B As an example, the assembly portion 14C4 is shown as a convex region protruding from the frame body 14Z toward the side. That is, the assembly portion 14C4 is shaped to be fitted together with the assembled portion 20C4 when assembled to the retainer 21.

[0307] The assembly portion 20C4 is provided on the opposing surface of the retainer 21 opposite to the panel body 11, and is a recessed shape formed in a direction away from the panel body 11. Furthermore, the assembly portion 20C4 is in a fitted state where it is engaged with the assembly portion 14C4 when the panel body 11 is assembled. That is, the convex assembly portion 14C4 and the recessed assembly portion 20C4 are fitted together. In other words, the outer peripheral surfaces of the assembly portion 14C4 and the assembly portion 20C4 are in a shape where they abut against each other and their outer peripheral surfaces are smoothly continuous when the panel body 11 is assembled to the retainer 21.

[0308] Thus, the assembly portion 14C4 of the frame 15 and the assembly portion 20C4 of the retainer 21 can be mutually fitted structures, for example, one can be convex and the other concave. With such shapes, the same effect as in the second embodiment described above can be obtained.

[0309] (Variation Example 6)

[0310] In this modified example, a frame 14 and an assembled part 20C with a shape different from the second embodiment and the modified example described above are described.

[0311] Figure 17A and Figure 17B This is an explanatory diagram of an example of the display device 101E in this modified example. The display device 101E is an example of the display device 101. Figure 17A This is a cross-sectional view of the perspective view of the display device 101E. Figure 17B This is an enlarged cross-sectional view of a portion (region E) of the display device 101E. For structures identical to those described in the above embodiments and variations, the same reference numerals are used, and detailed descriptions are omitted.

[0312] In this modified example, the frame 15 of the panel body 11 has an assembly part 14C5 instead of an assembly part 14C1. Additionally, the retainer 21 in this modified example has an assembly part 20C5 instead of an assembly part 20C1. The assembly part 14C5 is an example of the assembly part 14C, and the assembly part 20C5 is an example of the assembly part 20C.

[0313] exist Figure 17A As an example, a structure is shown in which an assembly part 14C5 is provided over the entire circumferential area of ​​the outer periphery of a rectangular frame 15. Additionally, in Figure 17A As an example, a structure is shown in which the assembled part 20C5 is provided along the entire circumferential region of the opening P provided in the retainer 21. The positions and ranges of the assembly part 14C5 and the assembled part 20C5 are not limited to any position or range where they interlock. Figure 17AAs shown in the diagram.

[0314] like Figure 17B As shown, the assembly part 20C5 of the retainer 21 and the assembly part 14C5 of the panel body 11 are the positions and shapes in which they fit together when the panel body 11 and the retainer 21 are assembled in the correct positions.

[0315] For example, such as Figure 17B As shown, the assembly part 14C5 is a strip-shaped area with a convex cross section that protrudes from the opposite side of the rectangular frame body 14Z toward the retainer 21 and is continuously formed along the outer periphery of the frame body 14Z.

[0316] The assembly portion 20C5 is disposed on the opposing surface of the retainer 21 opposite to the panel body 11, and is a recessed shape that clamps the strip-shaped assembly portion 14C5 with a convex cross-section from two directions intersecting the protruding direction relative to the convex shape. That is, the assembly portion 20C5 is a strip-shaped area disposed on the opposing surface of the retainer 21 opposite to the panel body 11 and with a recessed cross-section.

[0317] Thus, the assembly portion 14C5 of the frame 15 and the assembled portion 20C5 of the retainer 21 can be mutually fitted structures. For example, one could be a strip with a convex cross-section and the other a strip with a concave cross-section. Alternatively, the assembly portion 14C5 could be disposed over the entire circumferential region of the outer periphery of the frame 15, and the assembled portion 20C5 could be disposed along the entire circumferential region of the opening P of the retainer 21. That is, the assembly portion 14C5 and the assembled portion 20C5 could be a structure in which they fit together along the entire circumferential region of the outer periphery of the frame 15.

[0318] By adopting such a shape, the display device 101E of this modified example can achieve the same effect as the second embodiment described above, and can also achieve waterproofing.

[0319] (Variation Example 7)

[0320] In this modified example, a frame 14 and an assembled part 20C with a shape different from the second embodiment and the modified example described above are described.

[0321] Figure 18A and Figure 18B This is an explanatory diagram of an example of the display device 101F in this modified example. The display device 101F is an example of the display device 101. Figure 18A This is a perspective view of display device 101F. Figure 18B This is an enlarged view of a portion (region F) of the display device 101F. For structures identical to those described in the above embodiments and variations, the same reference numerals are used, and detailed descriptions are omitted.

[0322] In this modified example, the frame 15 of the panel body 11 has an assembly part 14C6 instead of an assembly part 14C1. Additionally, the retainer 21 in this modified example has an assembly part 20C6 instead of an assembly part 20C1. The assembly part 14C6 is an example of the assembly part 14C, and the assembly part 20C6 is an example of the assembly part 20C.

[0323] like Figure 18A As shown, the assembly part 14C6 may be a part in which one of the four corners of the four sides of the outer perimeter of the rectangular frame 15 is formed into a specific shape. Figure 18A As an example, one of the four corners of the outer perimeter of a rectangular frame 15 is shown to have a different shape from the other three corners. Specifically, as... Figure 18B As shown, for example, assembly part 14C6 is one corner of surface C, which is 45 degrees away from the four corners of the outer periphery of the rectangular frame 15. Furthermore, the angle of surface C is an example and is not limited to 45 degrees.

[0324] In addition, such as Figure 18A and Figure 18B As shown, the assembly portion 20C6 is one of the four corner portions located on the outer periphery of the opening P of the retainer 21, and is a portion that follows the shape of the outer periphery of the assembly portion 14C6. The assembly portion 20C6 is located at the position where the assembly portion 14C6 should be positioned when the panel body 11 is correctly assembled to the retainer 21.

[0325] In addition, such as Figure 18A As shown, the shapes of the other three corners of the outer periphery of the opening P of the retaining body 21, which are not the objects to which the assembly part 14C6 is configured, are different from the outer periphery of the assembled part 20C6. They are the shapes of the outer periphery of the three corners other than the assembly part 14C6 along the outer periphery of the frame 15.

[0326] By adopting such a shape, the display device 101F of this modified example can achieve the same effect as the second embodiment described above, and can prevent the panel body 11 from being assembled to the holder body 21 at an incorrect angle.

[0327] (Fourth implementation)

[0328] In the above embodiments and variations, the panel body 10 (panel body 11) and the holder 20 (holder 21) are described as being separately constructed and assembled during the manufacture of the display device 100 (display device 101).

[0329] In addition, panel body 10 and retainer 20, or panel body 11 and retainer 21, can also be integrally formed structures.

[0330] Figure 19This is a schematic diagram of an example of the display device 102 of this embodiment. Figure 19 This is a schematic diagram showing the display device 102 broken down into its constituent parts.

[0331] The display device 102 is the same as the display device 100 of the above embodiment and the display device 101 of the above modified example, except that it has an integral molded body 50 formed by integrally molding the panel body 10 and the retaining body 20.

[0332] In addition, Figure 19 As an example, the display device 102 is shown to also include an accessory component 66. The accessory component 66 is a component provided with a button for accepting user operation. In addition, the display devices 100 and 101 described above can also be structures that include other components such as the accessory component 66.

[0333] The one-piece molded body 50 is formed by integrally molding the panel body 10 and the retainer body 20. Alternatively, the one-piece molded body 50 can also be formed by integrally molding the panel body 11 and the retainer body 21.

[0334] The integral molded body 50 can be manufactured, for example, by using insert molding or the like. For example, the integral molded body 50 can be manufactured by using insert molding or the like: the panel body 10 or panel body 11 manufactured in the same manner as in the above embodiment is again housed in the mold, and heated molten resin material of the retainer 20 or retainer 21 is injected into the mold.

[0335] As described above, the display device 102 of this embodiment includes a panel body 10 and a retainer body 20, or a one-piece molded body 50 obtained by integrally molding a panel body 11 and a retainer body 21.

[0336] Therefore, this embodiment can provide a display device 102 that further suppresses damage and is easier to handle, in addition to the effects of the above-described embodiments and their modifications. Furthermore, by providing a one-piece molded body 50, the panel body 10 and the holder 20, or the panel body 11 and the holder 21, can have an aesthetic design.

[0337] Furthermore, in the above embodiments and modifications, the frame 14 and frame 15 that surround the end face of the plate member 12 in a frame-like manner have been described. However, the frame provided by the panel body 10 and panel body 11 may also have, for example, a shape that extends together with the frame-like portion surrounding the end face of the plate member 12. Thus, it may also constitute part of the appearance design of the first panel and housing of the display device 100, display device 101 and display device 102 manufactured by assembly.

[0338] Furthermore, in the above embodiments and variations, examples of panel bodies 10 and 11 having plate-shaped members 12 with a generally rectangular shape have been described. However, the plate-shaped members 12 used in panel bodies 10 and 11 may also be shapes other than rectangles, such as circles, ellipses, or other polygons.

[0339] While some embodiments of this utility model have been described, these embodiments are shown by way of example and are not intended to limit the scope of the utility model. These embodiments can be implemented in various other ways, and various omissions, substitutions, and modifications can be made without departing from the spirit of the utility model. These embodiments and their variations are included in the scope and spirit of the utility model, and likewise included in the technical solutions described in the claims and their equivalents.
