Description

Technical Field

[0001] This invention relates to the field of 3D displays, and more particularly to a method for processing a checkerboard-patterned three-dimensional display film. Background Technology

[0002] With the continuous development of the 3D display industry, 3D display technology is widely used in various fields. However, the higher the market demand, the higher the requirements for 3D displays become. Currently, 3D displays are generally achieved through 3D display screens, which are equipped with three-dimensional display modules that can present images, videos, and other content to people in 3D form.

[0003] However, 3D display modules manufactured using traditional processes are prone to air bubbles, resulting in unclear images and significantly impacting the viewing experience. Furthermore, traditionally manufactured 3D display modules contain an extra layer of film inside. Light emitted from the LEDs in the module is refracted through this film, causing changes in the angle of light emission. Consequently, the colors of the same image displayed on the 3D display module will shift when viewed from different angles. Summary of the Invention

[0004] This invention provides a method for processing a checkerboard-patterned 3D display film, solving the problem that traditional processes easily produce air bubbles in 3D display modules, affecting the viewing experience. It also addresses the issue that light emitted from LEDs in traditionally manufactured 3D display modules is easily refracted, causing changes in the emission angle and resulting in color shifts in the same displayed image when viewed from different angles.

[0005] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is to provide a processing method for a checkerboard-format three-dimensional display film, including the following steps: cutting, wherein the first polarizing film and the second polarizing film are two different types of polarizing films; the first polarizing film is pasted on the first carrier film and cut to form a plurality of first polarizing sheets arranged in an array on the first carrier film; the second polarizing film is pasted on the second carrier film and cut to form a second polarizing mesh, the second polarizing mesh having a plurality of second through holes arranged in an array; and the second carrier film is removed; the shape, size, position and number of the second through holes are adapted to the shape, size, position and number of the first polarizing sheets; combining, wherein the second polarizing mesh is pasted on the first carrier film, and the plurality of second through holes are correspondingly arranged around the periphery of the plurality of first polarizing sheets, the second polarizing mesh and the plurality of first polarizing sheets complement each other to form a checkerboard-format three-dimensional display film; pasting, wherein the three-dimensional display film above the first carrier film is correspondingly pasted onto the surface of the lamp beads of the three-dimensional display module, and then the first carrier film is removed.

[0006] In some embodiments, after the cutting step, the first polarizing film is cut, it further includes a first polarizing mesh having a plurality of first through holes arranged in an array. After the second polarizing film is cut, it further includes a plurality of second polarizing sheets arranged in an array above the second carrier film. Correspondingly, the assembly step further includes attaching the first polarizing mesh to the second carrier film, and the plurality of first through holes correspondingly surrounding the periphery of the plurality of second polarizing sheets. The first polarizing mesh and the plurality of second polarizing sheets complement each other to form another three-dimensional display film in a checkerboard pattern. Correspondingly, the pasting step further includes pasting the three-dimensional display film above the second carrier film to the surface of the LED beads of the three-dimensional display module, and then removing the second carrier film.

[0007] In some embodiments, the shape of the plurality of first polarizers is square, and the shape of the second through hole is also square.

[0008] In some embodiments, the cutting step includes setting layer parameters for the laser machine to activate a checkerboard cutting mode.

[0009] In some embodiments, the cutting method further includes placing a steel mesh on top of the polarizing film to be cut and fixing it, and setting the layer parameters of the laser machine to start the row and column cutting mode.

[0010] In some embodiments, the assembly step further includes an inspection to ensure the assembled three-dimensional display film is qualified; if qualified, the pasting step is performed; if unqualified, the three-dimensional display film is adjusted until qualified.

[0011] In some embodiments, the pasting step further includes brushing on a first adhesive, wherein the side of the three-dimensional display film away from the first carrier film is a first surface, and the side of the three-dimensional display film close to the first carrier film is a second surface; before pasting, a layer of the first adhesive is brushed onto the first surface, and the first adhesive covers the first surface.

[0012] In some embodiments, after the pasting step, the process further includes curing, in which the first colloid is cured using an ultraviolet lamp and the first carrier film is removed.

[0013] In some embodiments, after the curing step, a second colloid is applied to the second surface of the three-dimensional display film, and the second colloid covers the second surface.

[0014] In some embodiments, the step of applying the second colloid further includes attaching a protective film, which is applied over the second colloid to protect the three-dimensional display module.

[0015] The beneficial effects of this invention are as follows: This invention discloses a processing method for a checkerboard-format three-dimensional display film, comprising the following steps: cutting, wherein the first polarizing film and the second polarizing film are two different types of polarizing films; the first polarizing film is pasted on top of the first carrier film and cut to form multiple first polarizing sheets arranged in an array on top of the first carrier film; the second polarizing film is pasted on top of the second carrier film and cut to form a second polarizing mesh, the second polarizing mesh having multiple second through holes arranged in an array; and the second carrier film is removed; the shape, size, position, and number of the second through holes are adapted to the shape, size, position, and number of the first polarizing sheets. Assembling, the second polarizing mesh is pasted on the first carrier film, and the multiple second through holes are correspondingly arranged around the periphery of the multiple first polarizing sheets; the second polarizing mesh and the multiple first polarizing sheets complement each other to form a checkerboard-format three-dimensional display film. Pasting, the three-dimensional display film above the first carrier film is correspondingly pasted onto the surface of the LED beads of the three-dimensional display module, and then the first carrier film is removed. Using the above method, air bubbles on the 3D display module manufactured by traditional processes can be eliminated, improving the appearance quality of the 3D display module and making the display image clearer, thereby enhancing the user's viewing experience; in addition, removing the first carrier film after pasting can effectively solve the problem of color shift in the display image of the 3D display module when viewed from different angles.

[0028] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0029] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0030] Figure 1 This is a schematic flowchart of the processing method for the checkerboard-patterned three-dimensional display film provided by the present invention. Figure 1 As shown, the processing method of the checkerboard-patterned 3D display film includes:

[0031] Step S1: Cutting. The first polarizing film and the second polarizing film are two different types of polarizing films. The first polarizing film is pasted on the first carrier film and then cut to make multiple first polarizing sheets arranged in an array on the first carrier film. The second polarizing film is pasted on the second carrier film and then cut to make a second polarizing mesh. The second polarizing mesh has multiple second through holes arranged in an array. At the same time, the second carrier film is removed. The shape, size, position and number of the second through holes are adapted to the shape, size, position and number of the first polarizing sheets.

[0032] Step 2 S2: Assembly. The second polarizing mesh is attached to the first carrier film, and multiple second through holes are correspondingly arranged around the periphery of multiple first polarizers. The second polarizing mesh and multiple first polarizers complement each other to form a checkerboard pattern three-dimensional display film.

[0033] Step 3 S3, Adhere: Adhere the 3D display film above the first carrier film to the surface of the LED beads in the 3D display module.

[0034] Step 4 (S4): Curing. Using a UV lamp, the first colloid is cured and the first carrier film is removed.

[0035] Step 5S5: Apply a second colloid. Apply a layer of the second colloid to the second surface of the 3D display film, covering the second surface.

[0036] The processing method of the checkerboard-patterned three-dimensional display film provided by this invention can eliminate air bubbles on the three-dimensional display module manufactured by traditional processes, improve the appearance quality of the three-dimensional display module, and make the display image clearer, thereby improving the user's viewing experience; in addition, removing the first carrier film after pasting can effectively solve the problem of color shift in the display image of the three-dimensional display module when viewed from different angles.

[0037] The processing method of the above-mentioned chessboard-patterned three-dimensional display film is described in detail below with specific embodiments. (See reference...) Figures 1 to 12 The steps include:

[0038] S1: Cutting. The first polarizing film 1 and the second polarizing film 2 are two different types of polarizing films. The first polarizing film 1 is pasted on the first carrier film 3 and then cut to make multiple first polarizing sheets 11 arranged in an array on the first carrier film 3. The second polarizing film 2 is pasted on the second carrier film 4 and then cut to make a second polarizing mesh 22. The second polarizing mesh 22 has multiple second through holes 21 arranged in an array. At the same time, the second carrier film 4 is removed. The shape, size, position and number of the second through holes 21 are adapted to the shape, size, position and number of the first polarizing sheets 11.

[0039] In this design, both the first polarizing film 1 and the second polarizing film 2 can be either left-handed or right-handed polarizing films. When the first polarizing film 1 is a left-handed polarizing film, the second polarizing film 2 is a right-handed polarizing film; when the first polarizing film 1 is a right-handed polarizing film, the second polarizing film 2 is a left-handed polarizing film.

[0040] like Figure 2 As shown, in this embodiment, the first polarizing film 1 is attached above the first carrier film 3, and the second polarizing film 2 is attached above the second carrier film 4. The first carrier film 3 and the second carrier film 4 are two identical transparent films, which can provide support for the first polarizing film 1 and the second polarizing film 2 during cutting.

[0041] Furthermore, a laser machine is used to cut the two types of polarizing films separately. In this embodiment, the cutting method is as follows: the laser machine's layer parameters are set to activate its checkerboard cutting mode. After the laser machine is powered on, the layers and related parameters of the laser machine are set using pre-designed cutting data, causing it to begin cutting the polarizing film in a checkerboard pattern. That is, at set intervals, the laser machine cuts the polarizing film into a set shape, with the ends connected. The cutting trajectory is as follows: Figure 3 As shown, the arrow indicates the cutting direction. After cutting is complete, turn off the laser machine.

[0042] In some embodiments, the cutting method may also involve setting layer parameters for the laser machine to activate its row and column cutting mode. In addition to the laser machine, this method requires equipment such as... Figure 4 The steel mesh 7 shown is rectangular in shape. A steel plate 71 is located on the upper surface of the steel mesh 7, and multiple uniformly arranged steel holes 711 are drilled through the steel plate 71. In use, the polarizing film to be cut and its underlying support film are attached together to the underside of the steel plate 71, and then secured to the back of the steel mesh 7 using clamps to fix the polarizing film to be cut. The assembled assembly is placed inside the laser machine, which is then turned on. Its layers and related parameters are set to perform row and column cutting of the polarizing film. That is, the laser machine starts from the apex of the polarizing film and makes straight-line cuts along the steel holes 711 on the steel plate 71, with the cutting trajectory as shown. Figure 5 As shown, the arrow indicates the cutting direction. After cutting, the steel mesh 7, the fixture, and the polarizing film are separated, and the laser machine is turned off. Using the steel mesh 7 to cut the polarizing film in a row-and-column cutting pattern reduces the workload and time of the laser machine, significantly improving cutting efficiency.

[0043] like Figure 6 As shown, after the first polarizing film 1 is cut, multiple first polarizers 11 of the same size are formed. The multiple first polarizers 11 are evenly distributed in an array above the first carrier film 3, and each first polarizer 11 is square in shape.

[0044] like Figure 7 As shown, the second polarizing film 2 is cut into a second polarizing mesh 22. The second polarizing mesh 22 has multiple second through holes 21 of the same size arranged in an array. Each second through hole 21 is also square in shape and is aligned with... Figure 6 The first polarizer 11 is the same size. Simultaneously, the multiple second through holes 21 and the multiple first polarizers 11 are also positioned identically on the two carrier films. After the second polarizing film 2 is cut, the second carrier film 4 beneath it is removed.

[0045] In this embodiment, the first polarizer 11 and the second through-hole 21 are both square in shape, which can better adapt to the shape of a single LED bead 61 on the 3D display module 6. Compared with a circle, the square size can completely cover a single LED bead 61, preventing the light emitted by the LED bead 61 from leaking out, thereby effectively solving the crosstalk problem caused by light leakage from the LED bead 61.

[0046] S2: Combination, the second polarizing mesh 22 is attached to the first carrier film 3, and multiple second through holes 21 are correspondingly arranged around the periphery of multiple first polarizers 11. The second polarizing mesh 22 and multiple first polarizers 11 complement each other to form a checkerboard pattern three-dimensional display film 5.

[0047] like Figure 8 As shown, the second polarizing mesh 22 is attached above the first carrier film 3, and each second through hole 21 of the second polarizing mesh 22 is positioned in a one-to-one correspondence with the first polarizer 11, so that the first polarizer 11 completely fills the second through hole 21 of the second polarizing mesh 22. After combination, the second polarizing mesh 22 and the first polarizer 11 complement each other to form a checkerboard pattern three-dimensional display film 5.

[0048] Furthermore, after assembly, the 3D display film 5 needs to be inspected for any misalignment or offset. If it is qualified (meets the requirements), proceed to step S3: pasting; if it is unqualified or has problems (such as misalignment or offset), the 3D display film 5 needs to be adjusted until it meets the requirements, and then proceed to step S3: pasting.

[0049] S3: Adhere, after attaching the three-dimensional display film 5 above the first carrier film 3 to the surface of the lamp bead 61 of the three-dimensional display module 6, remove the first carrier film 3.

[0050] like Figure 9As shown, the side of the 3D display film 5 away from the first carrier film 3 is the first surface 51, and the side of the 3D display film 5 close to the first carrier film 3 is the second surface 52. A layer of first adhesive 8 is brushed onto the first surface 51 using a glue brush, so that the first adhesive 8 covers the first surface 51. In this embodiment, the glue brush is an ink coating roller with threads on its surface. When using it, the first adhesive 8 is applied to the glue brush, filling the gaps between the threads. The two ends of the glue brush are held with both hands, and the first adhesive 8 is pressed evenly onto the first surface 51 of the 3D display film 5. This is repeated several times until layers of adhesive are formed on the first surface 51. Using a glue brush to apply adhesive to the 3D display film 5 helps to eliminate air bubbles inside the first adhesive 8, so that the light emitted by the LED beads 61 on the 3D display module 6 will not produce a polarization problem after passing through the first adhesive.

[0051] In this embodiment, the first colloid 8 is a UV adhesive (UV is an abbreviation for Ultraviolet Rays), also known as shadowless adhesive or ultraviolet light curing adhesive. UV adhesive is a type of adhesive that must be cured by ultraviolet light irradiation and can be used as a bonding agent.

[0052] Furthermore, the 3D display film 5, after being coated with the first colloid 8, is flipped over and attached to the surface of the LED beads 61 of the 3D display module 6. It is then cured using a UV lamp. Afterward, the first colloid 3 is removed, and the assembled 3D display module 6 is as follows: Figure 10 As shown.

[0053] Removing the first carrier film 3 reduces air bubbles generated between the first carrier film 3 and the 3D display film 5 due to contact, maintaining the aesthetics of the 3D display module 6. Simultaneously, without air bubble interference, the light emitted by the LED beads 61 passes directly through the 3D display film 5 and is displayed, preserving the original colors of the image. Secondly, light undergoes refraction after passing through a medium, causing changes in the emission angle and inconsistent light transmission, which can easily lead to deviations in the emitted color. Removing the first carrier film 3 is equivalent to removing a layer of medium; the light emitted by the LED beads 61 no longer needs to undergo refraction and passes directly through the 3D display film 5 to be displayed, maintaining the original emission effect and effectively solving the problem of color shift when viewing the 3D display module 6 from different angles.

[0054] S4: Curing. The first colloid 8 is cured using a UV lamp, and the first carrier film 3 is removed.

[0055] Among them, such as Figure 10As shown, after step S3 is completed, the first colloid 8 is cured using a UV lamp. Ultraviolet light is invisible to the naked eye; it is a segment of electromagnetic radiation beyond visible light, with wavelengths ranging from 10 to 400 nm. The curing principle of UV adhesive is as follows: under UV light irradiation, the photoinitiator (or photosensitizer) in the UV adhesive absorbs ultraviolet light and generates active free radicals or cations, initiating monomer polymerization and cross-linking chemical reactions, causing the UV adhesive to transform from a liquid to a solid state within seconds.

[0056] S5: Apply the second colloid 9. Apply a layer of the second colloid 9 to the second surface 52 of the three-dimensional display film 5. The second colloid 9 covers the second surface 52.

[0057] In this embodiment, after curing, Figure 8 The entire film is placed upside down in a colloid tank filled with the second colloid 9, so that the second surface 52 of the 3D display film 5 is positioned below and in contact with the second colloid 9. After the second colloid 9 covers the second surface 52, it is heated and pressurized to remove air bubbles. After completion, the second colloid 9 becomes a disc shape, and its edges are trimmed to match the size of the second surface 52 of the 3D display film 5, ensuring a proper fit. Figure 11 As shown.

[0058] In this embodiment, the second colloid 9 is a transparent colloid with a hazy appearance, which will not affect the polarization effect of the 3D display film 5. Furthermore, the second colloid 9 also protects the 3D display film 5, preventing damage from impacts during use and extending its lifespan. Simultaneously, the second colloid 9 also has diffuse reflection and anti-glare effects, ensuring that the human eye is not stimulated when directly viewing the displayed image.

[0059] Furthermore, a protective film (not shown) is adhered above the second colloid 9, and this protective film is laminated to the 3D display film 5 through the second colloid 9. In this embodiment, the protective film is made of multiple materials such as PET (polyethylene terephthalate) and PC (polycarbonate). PET is a crystalline saturated polyester, a milky white or light yellow, highly crystalline polymer with a smooth and glossy surface. It is a common resin in daily life and can be divided into APET, RPET, and PETG. PC is an almost colorless, glassy, ​​amorphous polymer with excellent optical properties. The laminated protective film has anti-reflective, scratch-resistant, wear-resistant, oil-resistant, and easy-to-clean properties. It can protect the 3D display film 5 from damage and will not affect polarized light, while also improving the contrast of the 3D image.

[0060] In some embodiments, combined Figure 12In step S1: the cutting process, after the first polarizing film 1 is cut, it also includes a first polarizing mesh 12, which has a plurality of first through holes arranged in an array. After the second polarizing film 2 is cut, it also includes a plurality of second polarizers 23 arranged in an array above the second carrier film 4. The shape, size, position and number of the first through holes are adapted to the shape, size, position and number of the second polarizers 23.

[0061] Correspondingly, in step S2: the assembly step also includes attaching the first polarizing mesh 12 to the second carrier film 4, and having multiple first through holes correspondingly surrounding the periphery of multiple second polarizers 23, with the first polarizing mesh 12 and the multiple second polarizers 23 complementing each other to form another three-dimensional display film 5 in a checkerboard pattern.

[0062] Correspondingly, in step S3: pasting, the second carrier film 4 is pasted onto the surface of the LED bead 61 of the three-dimensional display module 6, and then the second carrier film 4 is removed.

[0063] The manufacturing process of the other three-dimensional display film 5 formed in the above embodiments, as well as the three-dimensional display module it constitutes and its effects, can be referred to as follows: Figures 2 to 11 The embodiments shown are not described in detail here.

[0064] Therefore, this invention discloses a method for processing a checkerboard-format three-dimensional display film, comprising the following steps: cutting, wherein the first polarizing film and the second polarizing film are two different types of polarizing films; the first polarizing film is pasted on top of the first carrier film and cut to form multiple first polarizing sheets arranged in an array on top of the first carrier film; the second polarizing film is pasted on top of the second carrier film and cut to form a second polarizing mesh, the second polarizing mesh having multiple second through holes arranged in an array; and the second carrier film is removed; the shape, size, position, and number of the second through holes are adapted to the shape, size, position, and number of the first polarizing sheets. Assembling, the second polarizing mesh is pasted on the first carrier film, and the multiple second through holes are correspondingly arranged around the periphery of the multiple first polarizing sheets, the second polarizing mesh and the multiple first polarizing sheets complementing each other to form a checkerboard-format three-dimensional display film. Pasting, the three-dimensional display film above the first carrier film is correspondingly pasted onto the surface of the LED beads of the three-dimensional display module, and then the first carrier film is removed. Using the above method, air bubbles on the 3D display module manufactured by traditional processes can be eliminated, improving the appearance quality of the 3D display module and making the display image clearer, thereby enhancing the user's viewing experience; in addition, removing the first carrier film after pasting can effectively solve the problem of color shift in the display image of the 3D display module when viewed from different angles.

[0065] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
