Description

Technical Field

[0001] The utility model relates to the technical field of 3D display, and in particular to a 3D display calibration device and a 3D film product packaging structure. Background Art

[0002] The real world is three-dimensional. When the human eye views an object, the images it sees have a positional difference. This deviation between the two images is called parallax. It is this parallax that allows people to distinguish the distance of objects and create a sense of three-dimensionality. Depending on the value of parallax, parallax can be categorized as positive, negative, and zero. Positive parallax creates the impression that objects are deep within the screen, while negative parallax creates the impression that objects are floating outside the screen. Zero parallax is the boundary between positive and negative parallax, where objects appear to be projected precisely onto the screen, often referred to as the zero plane. The human brain is an extremely complex nervous system that generates a three-dimensional perception by integrating two images with parallax into the optic nerve center and generating visual and psychological responses. Utilizing this principle, two images with parallax are displayed on a monitor, sent to the left and right eyes respectively, creating a 3D experience. The principle of naked-eye 3D display is generally to split the image displayed on the display through a grating or lens, so that the human eye receives different images to achieve 3D display. Among them, the slit grating display blocks the displayed content by placing a slit with appropriate parameters in front of the display panel. After passing a certain distance, the light reaching the human eye can be separated, and the two eyes receive two images with parallax; the cylindrical lens type also uses the same principle, but the implementation method is replaced by a lens instead of a slit. The lens's refraction of light is used to refract different display contents to different places in space. When it reaches the human eye, the displayed content is separated, so that the human eye receives two images with parallax, thus producing a three-dimensional effect.

[0003] Glasses-free 3D display technology is gaining popularity because it allows 3D viewing without the need for 3D glasses. The principle behind this technology is to cover the display screen of a display device (such as a mobile phone, tablet, or television) with a 3D film (e.g., a 3D film for mobile phones, tablets, or televisions). The displayed content is then rearranged to meet 3D display requirements, allowing the user's left and right eyes to see the left and right images, respectively, through the 3D film, achieving a 3D display effect. In practice, after attaching the 3D film to the display device, the display's layout needs to be calibrated to ensure that it matches the film's placement, resulting in the best 3D viewing experience.

[0004] 3D film products typically include a 3D film or a film applicator or a film applicator equipped with a 3D film. Existing 3D film products are typically sold in packaging boxes, which are typically equipped with a blister tray. To facilitate calibration, the prior art discloses a number of 3D calibration devices. Using a 3D calibration device facilitates more convenient calibration of a display device after a 3D film has been applied. For example, Chinese patent CN 108366248 A discloses a 3D calibration device, Chinese patent CN 213342499 U discloses a 3D display calibration device, and Chinese patent CN 207706339 U discloses a packaging box and a 3D self-calibration system, all of which can calibrate a display device after a 3D film has been applied. However, the existing technology usually uses the box body and / or box lid of a packaging box (such as a packaging box for a 3D film) to construct a 3D calibration device. On the one hand, the box body and box lid of the existing packaging box are usually made of cardboard. As the outer packaging of the product, they are very easy to be deformed or even damaged during actual transportation. When used in the calibration process, it will affect the calibration effect and is not conducive to improving the calibration accuracy. On the other hand, since the packaging box is the outer packaging of the product, it needs to have a certain strength and deformation resistance, so the box body and box lid in the packaging box are relatively large in mass and heavy in weight. When using them to construct a 3D calibration device, it is necessary to configure them with supporting components with greater load-bearing capacity and thicker thickness, which makes the cost of the existing 3D calibration device higher and is not conducive to improving economic efficiency. In addition, the existing 3D calibration device also has the problem of cumbersome construction process, which makes it inconvenient to use, and needs to be solved urgently. Utility Model Content

[0005] The first aspect of the present invention aims to solve the problems of the prior art of using a packaging box to build a 3D calibration device, which are higher cost, inconvenient to use, and easily affect the calibration accuracy. A new 3D display calibration device is provided, which has a more reasonable structural design, is not only lower cost and more convenient to use, but also can effectively ensure the calibration accuracy. The main concepts are:

[0006] A 3D display calibration device includes a tray for supporting a product, and a light reflecting component is provided on the back of the tray.

[0007] The two opposite sides of the back of the tray are respectively connected with supporting components, and the supporting components include a first connecting plate connected to the tray, a second connecting plate connected to the first connecting plate, and a third connecting plate connected to the side of the second connecting plate.

[0008] There are folds between the first connecting plate and the second connecting plate, and between the second connecting plate and the third connecting plate, respectively, and the supporting component is folded and unfolded through the folds.

[0009] The third connecting plate is provided with a connecting portion. When both supporting members are unfolded, the two third connecting plates are interlaced with each other and connected via the connecting portion.

[0010] The tray is supported by at least two second connecting plates.In this solution, a tray is configured so that the tray can be used to support products such as 3D films; a light-reflecting component is provided on the back of the tray so that the light-reflecting component does not affect the tray's support of the 3D film products. Not only can the light-reflecting component be used in conjunction with the display device for calibration, but the light-reflecting component is not placed on the box body and box lid of the packaging box, and the entire calibration process does not require a packaging box, thereby effectively solving the drawbacks of using a packaging box to build a 3D calibration device in the prior art; supporting components are connected to opposite sides of the back of the tray, and creases are reserved on the supporting components so that the supporting components can be folded and unfolded through the reserved creases, which is convenient for production and assembly, as well as for user use, and makes the folding and unfolding actions of the supporting components more regular and uniform, thereby The folding and unfolding effects can be effectively controlled, so that users with different experience levels can unfold the support component to a predetermined position, ensuring more stable calibration accuracy; by configuring the support component to include a first connecting plate, a second connecting plate and a third connecting plate that are interconnected, on the one hand, the support component can be integrally formed, the process is simpler and the cost is lower; on the other hand, the first connecting plate can be used to conveniently connect the tray, and the second connecting plate that has been unfolded into place can support the tray at a certain height so that the light reflecting component faces downward, and at the same time, space for placing the display device can be formed on the two second connecting plates. When in use, the display device to be calibrated only needs to be placed flat between the two second connecting plates, and the display device can correspond to the upper The light reflecting component can realize the automatic calibration function through the cooperation of the light reflecting component and the display device, which is very simple and convenient; by configuring the third connecting plate in the supporting component and configuring a folding line between the third connecting plate and the second connecting plate, so that the third connecting plate can be rotated relative to the second connecting plate, it is convenient to fold and unfold the third connecting plate, and at the same time, a connecting part is configured on the third connecting plate so that the two third connecting plates that are unfolded into place can be connected together through the connecting part. On the one hand, since the unfolded third connecting plate and the unfolded second connecting plate are in different orientations, the third connecting plates connected to each other can play a structural reinforcement role for the unfolded supporting component, which can effectively improve the bearing capacity and structural stability of the supporting component, and is more conducive to High-precision calibration; on the other hand, the two second connecting plates can be connected together by a third connecting plate, which can limit and constrain the second connecting plates, and ensure that the spacing between the two second connecting plates after unfolding can be kept constant, which is conducive to the light reflecting component being in a horizontal state, ensuring that users of different experience can easily and simply make the light reflecting component in a horizontal state when using this device, so that it can better calibrate with the display device below, and can effectively guarantee or even improve the calibration accuracy and calibration effect; therefore, compared with the existing 3D calibration device, the structural design of this device is more reasonable, and has the characteristics of being lighter, lower cost, more convenient to use, and better calibration accuracy and calibration effect, which better meets market demand.

[0011] To solve the problem of improving calibration stability, the tray further includes a top and a side portion connected to the outer edge of the top, the side portion extending downward in a direction away from the upper surface of the top, and the top is constructed with an inwardly recessed lower groove, the lower groove being used to accommodate the product, and the light reflecting component is connected to the back of the lower groove. By constructing the tray to include a top and a side portion extending downward in a direction away from the upper surface of the top, and constructing an inwardly recessed lower groove on the top, not only can the lower groove be used to position and restrain the product, but the design of the entire tray is also more conducive to lightweighting the tray, thereby greatly reducing the load-bearing capacity requirements of the supporting components, so that the supporting components can more stably support the tray and form a more stable calibration device, which in turn is conducive to improving the stability and reliability of the calibration device.

[0012] The second aspect of this invention addresses the problem of adapting to different product models. Furthermore, the top structure includes at least two inwardly recessed lower grooves, each with a different length and depth. This allows the use of lower grooves of varying lengths and depths to accommodate different 3D film product models, significantly improving the tray's versatility.

[0013] Preferably, the widths of the lower grooves are the same, for the sake of molding and cost saving.

[0014] Preferably, one side or both sides of the lower tank are further provided with grooves, so as to utilize the grooves to form a clearance space on one side or both sides of the lower tank, making it easier for users to take products on the tray.

[0015] In order to solve the problem of reducing calibration errors and improving calibration effects, the tray is further constructed as a rectangular structure, with two first connecting plates respectively connected to the sides of the tray at both ends, and the second connecting plate folding and unfolding along the length of the tray. By constructing the tray as a rectangular structure and connecting the two supporting components to the two ends of the tray respectively, the spacing between the two supporting components is increased, and the length of the second connecting plate in the supporting component is increased. When calibrating, the spacing between the light reflecting component and the lower end of the second connecting plate is increased. The larger the spacing, the smaller the calibration error, thereby effectively reducing the calibration error and improving the calibration effect. At the same time, the second connecting plate is folded and unfolded along the length of the tray so that the length of the second connecting plate can adapt to the length of the tray, thereby maximizing the length of the second connecting plate without affecting the folding and unfolding.

[0016] Preferably, the length of the second connecting plate is greater than or equal to 12 cm. This ensures that during calibration, the distance between the lower end of the second connecting plate and the light-reflecting component is greater than or equal to 12 cm, thereby facilitating that the distance between the display device to be calibrated and the upper light-reflecting component is greater than or equal to 12 cm, thereby effectively reducing calibration errors and improving calibration results.

[0017] Preferably, the length of the second connecting plate is 18-30 cm, which can take into account both calibration accuracy and production, transportation and cost.

[0018] Preferably, the light reflecting component is attached to the back of the lower groove, which is not only convenient for production and assembly, but also simple in process and lower in cost.

[0019] Preferably, the tray is a blister tray, which is easy to shape and helps reduce costs, and can also greatly reduce weight, which is more conducive to lightweighting of the device.

[0020] To improve stability and reliability, it is preferred that the two second connecting plates be parallel to each other after the two third connecting plates are connected by the connecting portion. This not only allows the two parallel second connecting plates to more reliably and stably support the tray, but also effectively ensures the horizontality of the light reflective component, making it easier to keep the light reflective component parallel to the display screen. This makes calibration easier and more convenient, and effectively improves calibration accuracy and effectiveness.

[0021] Preferably, the two supporting components have the same structure and are symmetrically connected to the tray, which is beneficial for simplifying the structure and keeping the substrate in a horizontal state during calibration.

[0022] Preferably, the first connecting plate is adhered to the pallet. Adhesive connection of the first connecting plate and the pallet not only simplifies and facilitates assembly, but also provides a cost-effective solution to the connection problem between the first connecting plate and the pallet. Furthermore, the reliability of the connection between the first connecting plate and the pallet is effectively and cost-effectively improved, thereby providing stable support for the pallet during calibration.

[0023] Preferably, the connecting portion is a double-sided tape or glue layer. There is no need to process the third connecting plate, which is conducive to simplifying the process and reducing costs.

[0024] Preferably, the connection portion includes a socket configured on one of the third connection plates and a plug configured on the other third connection plate, and the connection is achieved by inserting the plug into the socket, which is conducive to reuse.

[0025] Preferably, the lower edge of the third connecting plate is flush with the lower edge of the second connecting plate. This effectively increases the contact area between the support component and the underlying tabletop and improves the stability of the support component, allowing it to more stably support the tray above. Furthermore, the third connecting plate can be used to block light from one side of the display device. By cooperating with the second connecting plate, the display device can be shielded from light on three sides, preventing external light from interfering with the calibration process, thereby further improving calibration accuracy and effectiveness.

[0026] The third aspect of this utility model addresses the existing issues with using glass lenses as light reflective components, such as heavy weight, fragility, and the risk of breakage and scratching. Furthermore, the light reflective component comprises a substrate and a reflective mirror layer disposed on the side of the substrate facing away from the tray. In this solution, the light reflective component is not a glass lens, but rather a substrate with a reflective mirror layer. This makes it lighter, less prone to breakage, and less prone to the risk of breakage and scratching.

[0027] Preferably, the substrate is a plastic plate, and / or the reflective mirror layer is an electroplated reflective mirror layer. Using a plastic plate as the substrate reduces weight and cost while also providing flexibility, making it less prone to breakage and scratching. Using an electroplated reflective mirror layer allows the reflective mirror layer to be formed directly on the substrate surface via single-sided electroplating, effectively reflecting light to meet calibration requirements while also significantly reducing costs.

[0028] Preferably, the first connecting plate is made of cardboard, and / or the second connecting plate is made of cardboard, and / or the third connecting plate is made of cardboard, which can reduce weight and cost while facilitating folding and unfolding.

[0029] A 3D film packaging structure includes a packaging box and a 3D display calibration device, wherein the 3D display calibration device is placed in the packaging box. Using the packaging box to store and wrap the 3D display calibration device not only protects the 3D display calibration device but also facilitates stacking and transportation.

[0030] Compared with the existing technology, the 3D display calibration device and 3D film product packaging structure provided by the utility model have a more reasonable structural design, which is not only lower in cost and lighter in weight, but also simpler and more convenient for users to use, and can effectively ensure the calibration accuracy, which is conducive to obtaining better calibration results.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0045] Example 1

[0046] This embodiment provides a 3D display calibration device, including a tray 1, a light reflecting component 2, and two supporting components 3, wherein:

[0047] The tray 1 is mainly used to support the product. In this embodiment, the product can preferably be a 3D film product. For example, the 3D film product can be a 3D mobile phone film or a film applicator (or a film applicator device, such as a hand-pull film applicator) or a film applicator provided with a 3D film or a 3D flat film. In implementation, the shape of the tray 1 can be adapted to the shape of the product. For example, when the product is a rectangular 3D mobile phone film or a film applicator or a film applicator provided with a 3D mobile phone film, the tray 1 is also preferably constructed in a rectangular structure, such as Figure 1-Figure 3 shown.

[0048] During implementation, the tray 1 can adopt an existing tray 1. In this embodiment, the tray 1 includes a top 12 and a side 13 connected to the outer edge of the top 12. The top 12 is configured with an inwardly concave lower groove 121. Figure 1 and Figure 2 As shown, the lower groove 121 is used to accommodate products, and the side portion 13 extends downward in a direction away from the upper surface of the top 12, as shown in FIG. Figure 1-Figure 3 As shown, the side portion 13 and the back of the lower groove 121 may not be connected. In implementation, the lower depth of the lower groove 121 may be equal to the height of the side portion 13 or less than the height of the side portion 13. The lower groove 121 is mainly used to position and restrain the product. The pallet 1 with this structure makes the entire pallet 1 lightweight and can greatly reduce the bearing capacity requirements of the support component 3, so that the support component 3 can support the pallet 1 more stably and form a more stable calibration device, which is beneficial to improve the stability and reliability of the calibration device. In implementation, the lower groove 121 is formed to adapt to the shape of the product, such as Figure 1-Figure 2As shown, in this embodiment, the lower groove 121 preferably adopts a rectangular structure, and the corners of the lower groove 121 are constructed as arc transitions. In implementation, the tray 1 can preferably adopt a blister tray 1, which is easy to form, helps reduce costs, and can greatly reduce weight, which is more conducive to the lightweighting of the device.

[0049] In this embodiment, the light reflecting member 2 is arranged on the back of the tray 1 so that the light reflecting member 2 does not affect the tray 1 in supporting the product. Figure 5 and Figure 6 As shown, in implementation, the light reflecting component 2 can be attached to the back of the lower groove 121 by glue or double-sided tape 35, which is not only convenient for production and assembly, but also simple in process and low in cost. In implementation, the light reflecting component 2 can be implemented using existing technology, for example, the light reflecting component 2 can be an existing glass lens or other reflective mirror surface.

[0050] In this embodiment, the two opposite sides of the back of the tray 1 are respectively connected to the supporting members 3, and the supporting members 3 include a first connecting plate 31 connected to the tray 1, a second connecting plate 32 connected to the first connecting plate 31, and a third connecting plate 33 connected to the side of the second connecting plate 32. Figure 4 and Figure 5 As shown, a fold 34 (or indentation) is preset between the first connecting plate 31 and the second connecting plate 32. At the same time, a fold 34 is also preset between the second connecting plate 32 and the third connecting plate 33, so that the support member 3 can realize the folding and unfolding functions through the fold 34. Figure 5-Figure 8 As shown, it is convenient for production and assembly, and convenient for users to use. It also makes the folding and unfolding actions of the support component 3 more regular and unified, so that the folding and unfolding effects can be effectively controlled, so that users with different experiences can unfold the support component 3 to a predetermined position, ensuring more stable calibration accuracy.

[0051] In practice, the two first connecting plates 31 can be connected to the side portions 13 at both ends of the tray 1, respectively. Figure 5 and Figure 6 As shown, during implementation, the shape of the first connecting plate 31 is adapted to the side portions 13 at both ends of the pallet 1. For example, the first connecting plate 31 can adopt a rectangular structure, and the width of the first connecting plate 31 is adapted to the width of the pallet 1. The first connecting plate 31 is adhered to the pallet 1. For example, the first connecting plate 31 is connected to the side portions 13 at both ends of the pallet 1 with double-sided tape 35 or glue, which not only makes the assembly simpler and more convenient, but also can solve the connection problem between the first connecting plate 31 and the pallet 1 at a low cost. At the same time, it can also effectively and cost-effectively improve the reliability of the connection between the first connecting plate 31 and the pallet 1, so as to stably support the pallet 1 during calibration.

[0052] In practice, the second connecting plate 32 may preferably adopt a rectangular structure, such as Figure 4-Figure 6 As shown, the upper end of the second connecting plate 32 is connected to the first connecting plate 31, and the upper end of the second connecting plate 32 is used to contact the support table during use. In this embodiment, the fold 34 between the first connecting plate 31 and the second connecting plate 32 is distributed along the width of the tray 1, so that the second connecting plate 32 can be folded and unfolded along the length of the tray 1. Therefore, during implementation, the width of the second connecting plate 32 can be configured to adapt to the width of the tray 1, and the length of the second connecting plate 32 can be configured to adapt to the length of the tray 1. This can maximize the length of the second connecting plate 32 without affecting folding and unfolding. During calibration, the distance between the light reflecting component 2 and the lower end of the second connecting plate 32 is larger. The larger the distance, the smaller the calibration error, thereby effectively reducing the calibration error and improving the calibration effect. At the same time, the second connecting plate 32 is folded and unfolded along the length of the tray 1, so that the length of the second connecting plate 32 can adapt to the length of the tray 1.

[0053] During implementation, the length of the second connecting plate 32 can be determined based on actual needs. However, since the distance between the light-reflecting component 2 and the display device below (such as a mobile phone 5, tablet, etc.) during calibration is related to the length of the second connecting plate 32, in a preferred embodiment, the length of the second connecting plate 32 can be preferably configured to be greater than or equal to 12 cm, so that during calibration, the distance between the lower end of the second connecting plate 32 and the light-reflecting component 2 is greater than or equal to 12 cm, thereby facilitating the distance between the display device to be calibrated and the light-reflecting component 2 above to be greater than or equal to 12 cm, thereby effectively reducing calibration errors and improving calibration effects. In a more preferred embodiment, the length of the second connecting plate 32 can be 15-30 cm, which can take into account both calibration accuracy and better production, transportation, and cost.

[0054] Since the third connecting plate 33 is connected to the side of the second connecting plate 32, when the second connecting plate 32 is unfolded to the vertical direction, the fold 34 between the third connecting plate 33 and the second connecting plate 32 is exactly in the vertical direction. Figure 4 and Figure 5As shown, the third connecting plate 33 can be rotated in the vertical direction to achieve the folding and unfolding function. During implementation, the two third connecting plates 33 connected to the two second connecting plates 32 are arranged relative to each other so that the two third connecting plates 33 can cooperate with each other after unfolding. In a further embodiment, the third connecting plate 33 is also provided with a connecting portion. When the two supporting parts 3 are unfolded, the two third connecting plates 33 can be connected together through the connecting portion. On the one hand, since the unfolded third connecting plate 33 and the unfolded second connecting plate 32 are in different orientations, the third connecting plates 33 connected to each other can play a structural reinforcement role for the unfolded supporting part 3, which can effectively improve the bearing capacity and structural stability of the supporting part 3, and is more conducive to high-precision calibration; on the other hand, the two second connecting plates 32 can be connected together through the third connecting plate 33, which can play a role of limiting and constraining the second connecting plate 32, and can ensure that the spacing between the two second connecting plates 32 after unfolding can be kept constant, which is conducive to the light reflecting part 2 being in a horizontal state, ensuring that users of different experiences can easily and simply make the light reflecting part 2 in a horizontal state when using this device, so that it can better calibrate with the display device below, and can effectively guarantee or even improve the calibration accuracy and calibration effect.

[0055] In practice, the connection portion can be implemented in a variety of ways. For example, in one embodiment, the connection portion can be a double-sided tape 35 or a glue layer, thereby eliminating the need to process the third connection plate 33, which is beneficial for simplifying the process and reducing costs. In practice, the sum of the lengths of the two third connection plates 33 needs to be configured to be greater than the distance between the two second connection plates 32 when they are in a vertical state, so that when the two third connection plates 33 are staggered, as shown in FIG. Figure 5 As shown, the two third connecting plates 33 are connected together via double-sided tape 35 or a glue layer. In this case, both third connecting plates 33 can preferably have a rectangular structure. For example, in this embodiment, double-sided tape 35 is provided on the side of one of the third connecting plates 33, and the double-sided tape 35 is covered with release paper. When the two third connecting plates 33 need to be connected, simply tear off the release paper, which is very convenient.

[0056] For example, in another embodiment, the connection portion may include a socket 331 configured on one of the third connection plates 33 and a plug 332 configured on the other third connection plate 33. The length direction of the socket 331 may be parallel to the length direction of the fold 34. Figure 9As shown, when in use, the connection can be achieved by inserting the plug 332 into the socket 331. This design is more conducive to the repeated use of the device. Similarly, it can be understood that in this case, the sum of the lengths of the two third connecting plates 33 needs to be constructed to be greater than the distance between the two second connecting plates 32 when they are in a vertical state, so that the two third connecting plates 33 can be staggered with each other, as shown in FIG. Figure 9 shown.

[0057] During implementation, the position of the third connecting plate 33 along the height direction of the second connecting plate 32 can be determined according to actual needs. Preferably, the lower edge of the third connecting plate 33 can be flush with the lower edge of the second connecting plate 32. Figure 5 、 Figure 6 and Figure 9 As shown, the second connecting plate 32 and the third connecting plate 33 are used to jointly support the tray 1, which can effectively increase the contact area between the support component 3 and the table below, and can effectively improve the stability of the support component 3, so that the support component 3 can more stably support the tray 1 above; in addition, it is also beneficial to use the third connecting plate 33 to block the light on one side of the display device. By cooperating with the second connecting plate 32, the effect of shading the three sides of the display device is achieved, preventing external light from interfering with the calibration process, which is more conducive to improving the calibration accuracy and calibration effect. Of course, during implementation, the lower edge of the third connecting plate 33 can be higher than the lower edge of the second connecting plate 32, such as Figure 10 As shown, at this time, only the second connecting plate 32 is used to support the tray 1 .

[0058] To improve stability and reliability, in a preferred embodiment, after the two third connecting plates 33 are connected through the connecting portion, the two second connecting plates 32 can be exactly parallel to each other, such as Figure 5 and Figure 6 As shown, not only can the two mutually parallel first connecting plates 31 be utilized to more reliably and stably support the tray 1, but the horizontality of the light reflecting component 2 can also be effectively ensured, which is more conducive to the light reflecting component 2 being parallel to the display screen. This allows the calibration work to be started more simply and conveniently, and can effectively improve the calibration accuracy and calibration effect.

[0059] During implementation, the structures of the two supporting components 3 can be identical, and the two supporting components 3 can be symmetrically connected to the tray 1, which is beneficial for simplifying the structure and ensuring that the substrate 21 is in a horizontal state during calibration.

[0060] In practice, the first connecting plate 31 , the second connecting plate 32 and the third connecting plate 33 may preferably be made of cardboard, which can reduce weight and cost and facilitate folding and unfolding.

[0061] The 3D display calibration device provided in this embodiment can not only utilize the cooperation between the light reflecting component 2 and the display device for calibration, but also the light reflecting component 2 is not placed on the box body and the box cover of the packaging box, and the entire calibration process does not require the box body and the box cover of the packaging box, thereby effectively solving the disadvantage of using the packaging box to build a 3D calibration device in the prior art. When the tray 1 supports a 3D mobile phone film, the process of using this 3D display calibration device to calibrate the mobile phone 5 can be: first install the 3D mobile phone film supported by the tray 1 on the screen of the mobile phone, then unfold the support component 3, and connect the third connecting plate 33 through the connecting part, and place the 3D display calibration device on the desktop 4 (a support table), as shown in FIG. Figure 11 As shown, at this time, the light reflecting component 2 in the 3D display calibration device is facing the desktop 4 and is parallel to the desktop 4; then the mobile phone 5 is placed between the two second connecting plates 32, and the screen of the mobile phone 5 is facing the light reflecting component 2 above and is parallel to the light reflecting component 2, and then the automatic calibration program installed on the mobile phone 5 is started, and the calibration work can be completed through the cooperation of the mobile phone 5 and the light reflecting component 2, which is very convenient, efficient and accurate. Similarly, when the tray 1 supports a film applicator provided with a 3D mobile phone film, the process of calibrating the mobile phone 5 using this 3D display calibration device can be: first take out the film applicator provided with a 3D mobile phone film from the tray 1, use the film applicator to stick the 3D mobile phone film to the screen of the mobile phone, then unfold the support component 3, and connect the third connecting plate 33 through the connecting part, and place the 3D display calibration device on the desktop 4 (a support table), as shown. Figure 11 As shown, at this time, the light reflecting component 2 in the 3D display calibration device is facing the desktop 4 and is parallel to the desktop 4; then the mobile phone 5 is placed between the two second connecting plates 32, and the screen of the mobile phone 5 is facing the light reflecting component 2 above and is parallel to the light reflecting component 2, and then the automatic calibration program installed on the mobile phone 5 is started, and the calibration work can be completed through the cooperation of the mobile phone 5 and the light reflecting component 2.

[0062] Example 2

[0063] In order to solve the problem of adapting to different models of products, the main difference between this embodiment 2 and the above embodiment 1 is that in the 3D display calibration device provided by this embodiment, the top 12 of the tray 1 is constructed with at least two inwardly concave lower grooves 121, and the lower grooves 121 are stacked in the vertical direction, such as Figure 1-Figure 3 As shown, one lower layer groove 121 is processed at the bottom of another lower layer groove 121, and the lengths of the lower layer grooves 121 are different. The depths of the lower layer grooves 121 can be the same or different, as shown in FIG. Figure 1-Figure 3 As shown, different lengths and depths of the lower slots 121 can be used to adapt to different types of products, which can significantly improve the versatility of the tray 1. In practice, the number of the lower slots 121 can be determined according to actual needs. For example, Figure 1-Figure 3 As shown, the top 12 of the tray 1 is constructed with three inwardly recessed lower grooves 121 to meet the supporting requirements of three different models and specifications of products.

[0064] In practice, the width of each lower groove 121 can be the same to facilitate molding and cost saving. In a more complete solution, a groove 122 is further provided on one or both sides of the lower groove 121. Figure 1-Figure 3 As shown, the groove 122 is used to form a clearance space on one side or both sides of the lower groove 121 to facilitate users to take the products on the tray 1.

[0065] Embodiment 3 is to solve the problem that the existing calibration device uses glass lenses as the light reflecting component 2, which is heavy, easy to break, and has the risk of breakage and scratching. The main difference between this embodiment 3 and the above embodiments is that in the 3D display calibration device provided by this embodiment, the light reflecting component 2 includes a substrate 21 and a reflective mirror layer 22 provided on the side of the substrate 21 away from the tray 1, such as Figure 9 and Figure 8 As shown, the light reflecting component 2 is not a glass lens, but a substrate 21 provided with a reflective mirror layer 22 is used as the light reflecting component 2, which is lighter in weight, has no problem of breakage, and has no risk of breakage and scratching.

[0066] In practice, the substrate 21 can preferably be made of a plastic plate, such as an acrylic plate or a polystyrene plate (PS plate). This reduces weight and cost while also providing flexibility, making it less prone to breakage and scratching. In this embodiment, the reflective mirror layer 22 can preferably be an electroplated reflective mirror layer 22. In practice, the reflective mirror layer 22 can be formed directly on the surface of the substrate 21 through single-sided electroplating. This not only effectively reflects light to meet calibration requirements, but also effectively reduces costs.

[0067] Example 4

[0068] This embodiment provides a 3D film product packaging structure, including the above-mentioned 3D display calibration device and a packaging box. During implementation, 3D film products such as a 3D mobile phone film or a film applicator or a film applicator provided with a 3D film or a 3D flat-panel film can be placed on a tray 1, and the supporting component 3 is folded under the tray 1. The entire 3D display calibration device can be placed in the packaging box, so that the packaging box can be used to store and wrap the 3D display calibration device, which not only protects the 3D display calibration device, but also facilitates stacking and transportation.

[0069] During implementation, the packaging box may be an existing packaging box, and the size of the packaging box only needs to be adapted to the size of the 3D display calibration device.

[0070] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
