Description

Technical Field

[0001] The present invention relates to a cover plate for a display device that can be easily installed and removed relative to the display device, and a packaging body for the display device using the cover plate. Background Technology

[0002] Patent document 1 describes a protective cover material for a display. Figure 1 The protective cover material shown is installed in a manner that covers the entire surface of the display section of the display module, and a curved portion of the protective cover material is set in a manner that covers the upper and lower surfaces of the bezel. Figure 3 The protective cover material shown is installed to cover the entire surface of the display section of the display module. A portion of the protective cover material covers the lower surface of the bezel and is bent to form a curved portion by wrapping around the back side of the display module. In any embodiment, the protective cover material is fixed to the surface of the display module using adhesive tape.

[0003] Patent Document 2 describes a cover film for a display device. This cover film has a front surface adhesive portion and protruding portions extending outwards from the upper, lower, left, and right edges of the front surface adhesive portion. The front surface adhesive portion of the cover film is adhered to the outer periphery of the display, and each protruding portion is bent in a manner that meanders towards the rear housing side, adhering to the outer surface of the protective component and the rear surface of the base portion.

[0004] Existing technical documents: Patent documents: Patent Document 1: Japanese Patent Application Publication No. 2008-304760 Patent Document 2: Japanese Patent Application Publication No. 2013-190576 Summary of the Invention

[0005] The problem that the invention aims to solve: The protective cover material described in Patent Document 1 is fixed to the surface of the display module by adhesive tape, making the installation and removal of the protective cover material complicated. In addition, in order to reliably fix the protective cover material to the display module, the adhesive force of the adhesive tape must be set to be strong. However, if the adhesive force is strong, the removal of the adhesive tape becomes difficult, and it is easy to cause the adhesive tape to be unable to be completely removed, leaving some adhesive residue on the surface of the display module.

[0006] In Patent Document 2, the cover film is also attached to the outer periphery of the display with a front surface adhesive portion and to the sides and back of the display with a protruding portion. In order to prevent the cover film from detaching, the front surface adhesive portion and the protruding portion need to exert strong adhesive force. Similar to the problem addressed by the invention described in Patent Document 1, it is not easy to peel the cover film off the display. In addition, some of the adhesive is likely to remain on the display.

[0007] The present invention was made to solve the above-mentioned prior art problems, and its object is to provide a cover plate for a display device that is easy to install and remove from the display device and does not produce adhesive adhesion and residue on the surface of the housing, as well as a packaging body for the display device using the cover plate.

[0008] Methods used to solve problems: This invention is a cover plate for covering a display device, the display device having a housing that internally houses a display unit and a transparent panel covering a display screen facing forward of the housing, the cover plate being characterized in that... The housing integrally comprises a front plate portion covering the front surface of the transparent panel, a rear plate portion covering the rear surface of the housing, and a connecting piece extending from the rear plate portion or the front plate portion. The front plate has a joining inner surface and an outer surface, the rear plate has opposing inner surfaces and outer surfaces, and the connecting piece has a joining inner surface and an outer surface. Each joining inner surface and each opposing inner surface is the same plate surface. At least the inner surface of the front plate and the inner surface of the connecting piece are re-peel adhesive surfaces. The inner surface of the front panel can be bonded to the front surface of the transparent panel, and the inner surface of the connecting piece can be bonded to the outer surface of the front panel or the outer surface of the rear panel.

[0009] Preferably, in the cover plate for the display device of the present invention, the entire area of ​​the plate surface, including the joining inner surface and the opposing inner surface, is a re-peeling adhesive surface.

[0010] Alternatively, in the cover plate for the display device of the present invention, the opposing inner surface of the rear plate is a non-adhesive surface.

[0011] For example, the entire area of ​​the plate surface, including the joining inner surface and the opposing inner surface, can be configured as a re-peeling adhesive surface, and a peeling plate is provided on the opposing inner surface.

[0012] Preferably, the cover plate for the display device of the present invention has a PET substrate film.

[0013] Furthermore, the present invention provides a packaging for a display device, comprising: a display device having a housing containing a display unit and a transparent panel covering a display screen facing forward of the housing; and a cover plate covering the display device, characterized in that... The cover plate integrally forms a front plate portion covering the front surface of the transparent panel, a rear plate portion covering the rear surface of the housing, and a connecting piece extending from the rear plate portion or the front plate portion. The front plate has a joining inner surface and an outer surface, the rear plate has opposing inner surfaces and outer surfaces, and the connecting piece has a joining inner surface and an outer surface. Each of the joining inner surfaces and the opposing inner surfaces is the same plate surface. At least the inner surface of the front plate and the inner surface of the connecting piece are re-peel adhesive surfaces. The inner surface of the front panel is bonded to the front surface of the transparent panel. The connecting piece extending from the rear panel extends toward the front of the display device, such that the inner surface of the connecting piece is bonded to the outer surface of the front panel; or, the connecting piece extending from the front panel extends toward the rear of the display device, such that the inner surface of the connecting piece is bonded to the outer surface of the rear panel.

[0014] Preferably, in the packaging of the display device of the present invention, the entire surface area of ​​the cover plate, including the joining inner surface and the opposing inner surface, is a re-peel adhesive surface. The surface roughness of the rear surface of the housing is greater than that of the front surface of the transparent panel, and the opposing inner surface of the rear panel is not bonded to the rear surface.

[0015] Alternatively, in the packaging of the display device of the present invention, the entire area of ​​the cover plate surface, including the joining inner surface and the opposing inner surface, is a re-peeling adhesive surface, and a peeling plate is provided on the opposing inner surface.

[0016] Preferably, in the packaging of the display device of the present invention, the cover plate has a PET substrate film.

[0017] Invention effects: This invention enables the simple mounting of a cover plate to a display device by bonding the inner surface of the re-peel adhesive surface of the front panel to the front surface of the transparent panel of the display device, and bonding the inner surface of the re-peel adhesive surface of the connecting piece to the outer surface of the front or rear panel. While the adhesive force of the re-peel adhesive surface is weak, the front surface of the transparent panel has a near-mirror surface roughness, allowing for reliable bonding by ensuring close contact between the inner surface of the front panel and the front surface of the transparent panel. Furthermore, the outer surfaces of the front or rear panel are also smooth and have low surface roughness, enabling reliable bonding by ensuring close contact between the inner surface of the connecting piece and each outer surface. On the other hand, the inner surface of the connecting piece can be easily peeled from the outer surface of the front or rear panel, and the inner surface of the re-peel adhesive surface of the front panel can also be easily peeled from the front surface of the transparent panel, thus facilitating cover plate removal.

[0018] By designating the entire surface area of ​​the panel, including the joining inner surface and the opposing inner surface, as a re-peel adhesive surface, it is not necessary to locally design the re-peel adhesive surface, thus easily constructing the cover plate. That is, the cover plate can be formed by cutting a substrate film with a re-peel adhesive layer covering the entire surface. The re-peel adhesive surface can be bonded by adhering closely to a surface with low surface roughness, such as the front surface of the transparent panel, but it is not easy to bond to a surface with high surface roughness, such as the rear surface of the housing. Therefore, even if the entire surface area of ​​the panel is a re-peel adhesive surface, it will not adhere to the surface of the housing other than the transparent panel, or even if it does adhere to the surface of the housing, its adhesive force becomes extremely weak, and the adhesive force relative to the surface of the housing will not become a resistance when removing the cover plate. Furthermore, no adhesive residue will remain on the surface of the housing. Moreover, since the peeling plate remains on the opposing inner surface of the rear panel, the opposing inner surface of the rear panel can be made a non-adhesive surface.

[0031] Figure 1 and Figure 2 The packaging body 1 of the display device according to the first embodiment of the present invention, Figure 3 and Figure 4 This indicates the display device 10 and the cover 20 that constitute the packaging body 1. Figure 5 and Figure 6This illustrates the structure of cover plate 20. In each figure, the Y1-Y2 direction represents the front-to-back direction, with Y1 representing the front and Y2 representing the rear. The X1-X2 direction represents the horizontal direction, with X1 representing the left and X2 representing the right. The Z1-Z2 direction represents the vertical direction, with Z1 representing the top and Z2 representing the bottom.

[0032] Figure 3 and Figure 4 The display device 10 shown is for vehicle use. Alternatively, the display device 10 can also be for home use, gaming, theater use, etc. The display device 10 has a housing 11. The housing 11 has a front surface 11a facing forward (Y1 direction) and a rear surface 11b facing backward (Y2 direction). In addition, the housing 11 has an upper side surface 11c facing upward (Z1 direction), a lower side surface 11d facing downward (Z2 direction), a left side surface 11e facing left (X1 direction), and a right side surface 11f facing right (X2 direction).

[0033] A display component is housed inside the casing 11. The display component consists of a display unit and an electronic circuit unit for driving the display unit. The display unit may be a liquid crystal display unit or an organic EL display unit, etc. Figure 3 As shown, a rectangular display window 12 opens onto the front surface 11a of the housing 11, and the display image of the display unit appears inside the display window 12. The display image faces forward (Y1 direction). A transparent panel 13 is provided on the front surface 11a of the housing around the display window 12, and the display image is covered by the transparent panel 13. The transparent panel 13 is formed of a transparent glass plate or a transparent resin plate such as an acrylic plate.

[0034] The housing 11 is die-cast from a lightweight metal material such as magnesium alloy. The rear surface 11b, upper side 11c, lower side 11d, left side 11e, and right side 11f are matte-finished surfaces, such as matte black surfaces. The front surface 13a of the transparent panel 13 is approximately mirror-like, so the surface roughness of the rear surface 11b, upper side 11c, lower side 11d, left side 11e, and right side 11f is sufficiently large compared to the front surface 13a of the transparent panel 13.

[0035] exist Figure 5 In this case, the cover 20 is unfolded into a flat shape, and the inner surface facing the display device 10 during packaging is shown towards the front. For example... Figure 6As shown in the cross-sectional view, the cover plate 20 has a substrate film BF. A re-peel adhesive layer AL is laminated on the inner surface of the substrate film BF, and the inner surface of the cover plate 20 becomes the re-peel adhesive surface. The substrate film BF of the cover plate 20 is made of a resin material with high bending rigidity, so that the re-peel adhesive surface of its inner surface is not easily in close contact with the uneven surfaces such as the matte-coated surface, i.e., the rear surface 11b of the housing 11. Preferably, the substrate film BF constituting the cover plate 20 has a bending strength of 90 MPa or more as measured by "ASTM: D790", and more preferably, it has a bending strength of 100 MPa or more as measured by "ASTM: D790". The substrate film BF that meets this condition is PET, PMMA, PA66, etc. The thickness of the substrate film BF is preferably 0.03 mm or more and 0.1 mm or less. In the embodiment, the substrate film BF of the cover plate 20 is a PET film with a thickness of 0.05 mm.

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, the cover plate 20 has a front plate portion 21, a rear plate portion 22, and a longitudinal intermediate portion 23 located between the front plate portion 21 and the rear plate portion 22. The front plate portion 21, the longitudinal intermediate portion 23, and the rear plate portion 22 are sequentially arranged longitudinally. Figure 5 As shown, a perforation line (perforation) 24 extending laterally (X1-X2 direction) is formed at the boundary between the front plate portion 21 and the longitudinal middle portion 23, and a perforation line 25 extending laterally is formed at the boundary between the longitudinal middle portion 23 and the rear plate portion 22.

[0037] like Figure 5 As shown, the left connecting piece 26 extends to the left (X1 direction) from the rear plate portion 22, and the right connecting piece 27 extends to the right (X2 direction) from the rear plate portion 22. A horizontal intermediate portion 28 is provided between the left connecting piece 26 and the rear plate portion 22, and a horizontal intermediate portion 29 is provided between the right connecting piece 27 and the rear plate portion 22. The rear plate portion 22, the horizontal intermediate portion 28, and the left connecting piece 26 are sequentially continuous in the left direction (X1 direction), and the rear plate portion 22, the horizontal intermediate portion 29, and the right connecting piece 27 are sequentially continuous in the right direction (X2 direction). A perforation line 31 extending longitudinally (Z1-Z2 direction) is formed at the boundary between the left connecting piece 26 and the horizontal intermediate portion 28, and a perforation line 32 extending longitudinally is formed at the boundary between the horizontal intermediate portion 28 and the rear plate portion 22. Similarly, a perforation line 31 is formed between the right connecting piece 27 and the horizontal middle portion 29, and a perforation line 32 is formed at the boundary between the horizontal middle portion 29 and the rear plate portion 22. The protrusion 33 protruding to the left from the left connecting piece 26 and the protrusion 34 protruding to the right from the right connecting piece 27 are integrated.

[0038] exist Figure 5In the inner surfaces of the cover plate 20 shown, the inner surface of the front plate portion 21 is the joining inner surface 21a, the inner surface of the left connecting piece 26 is the joining inner surface 26a, and the inner surface of the right connecting piece 27 is the joining inner surface 27a. The inner surface of the rear plate portion 22 is the opposing inner surface 22a. The inner surface of the longitudinal middle portion 23 is the middle inner surface 23a, the inner surface of the transverse middle portion 28 is the middle inner surface 28a, and the inner surface of the transverse middle portion 29 is the middle inner surface 29a. The joining inner surfaces 21a, 26a, 27a, the opposing inner surface 22a, and the middle inner surfaces 23a, 28a, and 29a form the same plate surface of the cover plate 20 (substrate film BF).

[0039] On the inner surfaces 21a, 26a, 27a of the cover plate 20, the opposing inner surface 22a, the intermediate inner surface 23a, 28a, 29a, and the inner surfaces of the tabs 33 and 34, such as Figure 6 As shown, a re-peel adhesive layer AL is provided on the surface of the substrate film BF, and the cover plate 20 appears in Figure 5 The entire inner surface of the cover plate 20, i.e., the entire surface of the plate, becomes the re-peel adhesive surface. The re-peel adhesive layer AL constituting the re-peel adhesive surface is a micro-adhesive layer, which is a silicone-based adhesive or an acrylic adhesive. Preferably, the re-peel adhesive layer AL has an ultra-micro adhesive force of about 0.5-30 mN / 25 mm as measured by "ASTM: D3330". The entire inner surface of the cover plate 20 is the re-peel adhesive surface, but when the surface opposite to the inner surface is installed on the display device 10, the outer surface facing outward is a non-adhesive surface without the re-peel adhesive layer AL.

[0040] like Figure 6 As shown in (B), at the tab 34, an adhesive tape 35 is adhered to the inner surface of the re-peel adhesive layer AL. The adhesive surface 35b of the adhesive tape 35 is bonded to the re-peel adhesive surface, and the non-adhesive surface 35a of the adhesive tape 35 appears on the inner surface side of the cover plate 20. The tab 33 on the left side has the same structure, and the inner surfaces of the left and right tabs 33 and 34 are non-adhesive surfaces.

[0041] Next, the installation and removal of the cover plate 20 in the packaging 1 of the display device will be described.

[0042] like Figure 3 and Figure 4 As shown, in the cover plate 20, by applying creases to the substrate film BF at the positions of the perforation lines 24 and 25, the front plate portion 21 and the rear plate portion 22 can be positioned opposite each other in the front-to-back direction (Y1-Y2 direction). In addition, by applying creases to the substrate film BF at the positions of the perforation lines 31 and 32 on the left and right sides, the left connecting piece 26 and the right connecting piece 27 extending from the rear plate portion 22 to the left and right can be positioned facing forward (Y1 direction).

[0043] In the process of installing the cover plate 20 onto the display device 10, the inner surface 21a of the front panel 21, which serves as the re-peel adhesive surface, is bonded to the front surface 13a of the transparent panel 13, and the rear surface 11b of the housing 11 is covered by the rear panel 22. The left connecting piece 26 extending to the left and the right connecting piece 27 extending to the right from the rear panel 22 extend towards the front of the display device 10, as shown... Figure 1 As shown, the re-peeling adhesive surface of the left connecting piece 26, i.e., the inner surface 26a of the joint, is bonded to the outer surface 21b of the front plate portion 21, and the re-peeling adhesive surface of the right connecting piece 27, i.e., the inner surface 27a of the joint, is bonded to the outer surface 21b of the front plate portion 21. Through this operation, as... Figure 1 and Figure 2 As shown, the packaging body 1 is formed by covering the display device 10 with a cover plate 20.

[0044] The re-peel adhesive surface of the inner surface of the cover plate 20 is a micro-adhesive layer with extremely weak adhesion. However, since the front surface 13a of the transparent panel 13 is close to a mirror and has extremely low surface roughness, the front panel 21 can maintain its adhesive bonding with the front surface 13a when the inner bonding surface 21a of the front panel 21 is pressed against the front surface 13a. In addition, the outer surface 21b of the front panel 21 facing forward (Y1 direction) is the film surface of the substrate film BF, which, like the front surface 13a of the transparent panel 13, is a smooth surface with extremely low surface roughness. Therefore, even though the adhesive force of the re-peel adhesive surfaces of the inner bonding surfaces 26a and 27a is extremely low, by pressing the inner bonding surface 26a of the left connecting piece 26 and the inner bonding surface 27a of the right connecting piece 27 against the outer surface 21b of the front panel 21, the state in which the left connecting piece 26 and the right connecting piece 27 are pressed against the outer surface 21b of the front panel 21 can be maintained.

[0045] exist Figure 1 and Figure 2 In the packaging 1 of the display device 10 shown, the front panel 21 of the cover plate 20 is in close contact with the front surface 13a of the transparent panel 13. Furthermore, the rear surface 11b of the housing 11 is covered by the rear panel 22 of the cover plate 20, the upper side 11c of the housing 11 is covered by the longitudinal middle portion 23 of the cover plate 20, and the left side 11e and right side 11f of the housing 11 are covered by the transverse middle portions 28 and 29 of the cover plate 20. This allows the display device 10 to be installed inside a vehicle with most of it covered by the cover plate 20, preventing damage to the display panel and housing 11 of the display device 10.

[0046] When removing the cover plate 20 from the display device 10, such as Figure 1As shown, the protrusions 33 and 34, which are located on the outer surface 21b of the front plate portion 21 of the cover plate 20 and are not engaged with the outer surface 21b, are used to peel the left connecting piece 26 and the right connecting piece 27 forward. Since the inner surface 26a of the left connecting piece 26 and the inner surface 27a of the right connecting piece 27 are re-peeling adhesive surfaces with very weak adhesive force, the left connecting piece 26 and the right connecting piece 27 can be easily peeled off from the outer surface 21b of the front plate portion 21 with relatively weak force.

[0047] Next, holding the left connecting piece 26 and the right connecting piece 27 by hand, lift the rear plate 22 from the rear (Y2 direction) upward (Z1 direction). The rear surface 11b of the housing 11 is coated with a matte finish, etc., and its surface roughness is greater than that of the front surface 13a of the transparent panel 13. In addition, the substrate film BF constituting the cover plate 20 is a film with high rigidity such as PET, which does not match the fine uneven shape of the rear surface 11b of the housing 11 and is difficult to adhere tightly. Therefore, even if the opposing inner surface 22a of the rear plate 22 is a re-peel adhesive surface, the opposing inner surface 22a will not stick to the rear surface 11b, and even if it is temporarily stuck, the rear plate 22 can be easily separated from the rear surface 11b. The inner surface 23a of the longitudinal middle portion 23 and the inner surfaces 28a and 29a of the transverse middle portions 28 and 29 of the cover plate 20 are also re-peeling adhesive surfaces. However, the surface roughness of the upper side 11c, left side 11e, and right side 11f of the housing 11 is greater than that of the front surface 13a of the transparent panel 13, so there is almost no adhesion, allowing the longitudinal middle portion 23 and the transverse middle portions 28 and 29 to separate from the housing 11. In addition, no adhesive layer will adhere to and remain on the rear surface 11b, upper side 11c, left side 11e, and right side 11f of the housing 11.

[0048] By lifting the rear panel 22 of the cover plate 20 upwards, the front panel 21 can be peeled off from the front surface 13a of the transparent panel 13, allowing the cover plate 20 to be removed from the display device 10. The inner bonding surface 21a of the front panel 21 is a re-peel adhesive surface, thus it can be easily peeled off from the front surface 13a of the transparent panel 13.

[0049] Figure 7 and Figure 8 This illustrates a modified example of the cover plate 20 used in the packaging body 1 of the display device according to the first embodiment. Figure 5 In the cover plate 20 shown, the entire area of ​​the inner surface facing forward is a re-peel adhesive layer. Therefore, the entire area of ​​the re-peel adhesive surface (except for the tabs 33 and 34) is covered by a peeling plate (release film). The peeling plate is peeled off before the operation of covering the display device 10 is performed, exposing the entire area of ​​the inner surface of the cover plate 20. Figure 7 and Figure 8In the modified example of the cover plate 20 shown, the peeling plate 38 remains only on the portion covering the opposing inner surface 22a of the rear plate portion 22, and the opposing inner surface 22a of the rear plate portion 22 with the remaining peeling plate 38 is designated as a non-adhesive surface. Even if a slightly stronger adhesive layer is used as a re-peel adhesive layer AL provided on the inner surface of the cover plate 20, since the opposing inner surface 22a of the rear plate portion 22 is a non-adhesive surface, the opposing inner surface 22a will not adhere to the rear surface 11b of the housing 11. Alternatively, an adhesive tape, such as the same adhesive tape 35 adhered to the inner surface of the tabs 33 and 34, can be applied to the opposing inner surface 22a of the rear plate portion 22 instead of the peeling plate 38, thus designating the opposing inner surface 22a as a non-adhesive surface.

[0050] Figure 9 and Figure 10 The packaging body 101 represents the display device according to the second embodiment of the present invention.

[0051] The cover plate 120 of the packaging body 101 in the second embodiment is formed continuously in the longitudinal direction by a front plate portion 21, a longitudinal middle portion 23, and a rear plate portion 22. Two longitudinal connecting pieces 126 extend downward (in the Z2 direction) from the left and right sides of the rear plate portion 22. The longitudinal middle portion 128 is located between the rear plate portion 22 and each of the longitudinal connecting pieces 126, and the rear plate portion 22, the longitudinal middle portion 128, and the longitudinal connecting pieces 126 are formed continuously in the longitudinal direction. Perforation lines 131 are formed at the boundary between each of the longitudinal connecting pieces 126 and the longitudinal middle portion 128, and perforation lines 132 are formed at the boundary between the longitudinal middle portion 128 and the rear plate portion 22. Figure 10 The cover plate 120 shown also has a re-peel adhesive surface covering the entire area of ​​the inner surface facing the display device 10, and the mating inner surface 126a of the longitudinal connecting piece 126 is also a re-peel adhesive surface. Each longitudinal connecting piece 126 has a downwardly protruding tab 133 integrally formed thereon, and adhesive tape is attached to the inner surface of each tab 133.

[0052] In the packaging process using the cover plate 120, after the inner surface 21a of the front panel 21 is bonded to the front surface 13a of the transparent panel 13 located in front of the display device 10, the rear panel 22 is positioned opposite the rear surface 11b of the housing 11 of the display device 10. Furthermore, the two longitudinal connecting pieces 126 extending downwards from the display device 10 are pulled forward, as...
