Description

Technical Field

[0001] This invention belongs to the field of projection equipment, and particularly relates to the structure of a screen. Background Technology

[0002] When projecting videos, large screens or giant screens are sometimes used to enhance the viewing experience. These screens require multiple smaller screens to be joined together to form a single giant screen. Current methods involve applying adhesive to the sides of the screens and bonding adjacent screens together. To protect the adhesive and increase the strength between adjacent screens, strips are usually attached to the side of the screen furthest from the incident light source. However, when the screen is large, a single strip may not provide sufficient adhesion, causing adjacent screens to detach and affecting the overall bonding effect. Summary of the Invention

[0003] The purpose of this invention is to provide a screen structure that addresses the technical problem in existing large-screen splicing technology where strips are only pasted on the side of the screen away from the incident light source. When the screen is large, the adhesion of a single strip is insufficient, and adjacent screens are prone to detachment.

[0004] The present invention is implemented as follows: a screen structure comprising: multiple screen panels, each screen panel having a splicing structure connected to adjacent screen panels, the splicing structure being a first splicing part or a second splicing part that cooperates with each other, the first splicing part and the second splicing part being spliced ​​together and fixed together to connect the multiple screen panels into one unit; a first strip, the first strip being fixed to the side of the screen panel near the incident light source, and the first strip being covered at the splicing point of two adjacent screen panels, the first strip being a transparent strip; and a second strip, the second strip being fixed to the side of the screen panel away from the incident light source, and the second strip being covered at the splicing point of two adjacent screen panels.

[0005] Furthermore, the structure of the curtain also includes at least one third strip, a portion of which is fixed to the first strip and another portion of which is fixed to the curtain. The third strip is a transparent strip, or the third strip includes reflective particles for diffuse reflection of incident light.

[0006] Furthermore, the structure of the curtain includes a pair of third strips, which are symmetrically arranged on both sides of the first strip. The third strips cover the first strip and are used for a smooth transition between the surface of the first strip and the surface of the curtain.

[0007] Furthermore, the structure of the curtain also includes a protective cover with an inner cavity, the protective cover being fixed to the side of the curtain away from the incident light source, and the second strip being located in the inner cavity.

[0008] Furthermore, the protective cover is provided with a through hole communicating with the inner cavity, the through hole being used to inject glue into the inner cavity, and the second strip is adhered to the inner wall of the protective cover by the glue.

[0009] Furthermore, the screen includes multiple sides, at least one of the sides is provided with the first splicing part or the second splicing part, and two adjacent screens are connected by the mutually cooperating first splicing part and second splicing part.

[0010] Furthermore, the first splicing part includes a protrusion, and the second splicing part includes a groove corresponding to the protrusion. The protrusion is inserted into the groove, and the protrusion is glued and fixed to the groove.

[0011] Furthermore, the protrusion is located at the middle of the side of the curtain, the groove is located at the middle of the side of the curtain, and the protrusion includes a pair of symmetrically arranged first adhesive surfaces, which are bonded to the inner wall of the groove.

[0012] Furthermore, the protrusion is located on a first side of the side surface of the screen, the protrusion includes a second adhesive surface, the groove is located on a second side of the side surface of the screen, and the second adhesive surface is bonded to the inner wall of the groove.

[0013] Furthermore, the first splicing part includes a plurality of protrusions evenly distributed along the width direction of the curtain, and the second splicing part includes a plurality of grooves matching the protrusions. The protrusions are inserted into the grooves one by one, and the protrusions are glued and fixed to the grooves.

[0014] The beneficial effects of this invention are as follows: Not only is a second strip provided on the side of the screen furthest from the incident light source, but a first strip is also added on the side of the screen closest to the incident light source. The first and second strips are positioned opposite each other on both sides of the screen, increasing the adhesion of the screen and providing advantages such as simple structure and good stability. Furthermore, the first strip is transparent, so even when fixed to the side of the screen closest to the incident light source, it will not affect the projection effect of the screen.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0028] It should also be noted that the directional terms such as left, right, up, and down in this embodiment are only relative concepts or are based on the normal use of the product, and should not be considered as restrictive.

[0029] As attached Figure 1-3The diagram illustrates the structure of a screen provided in Embodiment 1 of the present invention, comprising multiple screen panels 10. These multiple smaller screen panels 10 are spliced ​​together to form a giant screen, achieving a better viewing experience. For ease of splicing, each screen panel 10 has a splicing structure that connects to adjacent screen panels 10. This splicing structure consists of a first splicing part 12 or a second splicing part 13 that cooperates with each other. The first splicing part 12 and the second splicing part 13 are respectively disposed on two adjacent screen panels 10 that need to be spliced. After splicing, the first splicing part 12 and the second splicing part 13 are fixed together. In this embodiment, they are preferably glued together using adhesive 60, so that the multiple screen panels 10 are connected as a single unit to form a giant screen.

[0030] In this preferred embodiment, the screen 10 includes multiple sides 11. At least one side 11 of the screen 10 is provided with a first splicing portion 12 or a second splicing portion 13, and two adjacent screens 10 are connected by the mutually cooperating first splicing portion 12 and second splicing portion 13. To ensure the overall flatness after splicing, the width of the sides 11 of adjacent screens 10 is the same, and the only structural difference is between the first splicing portion 12 and the second splicing portion 13. After the first splicing portion 12 and the second splicing portion 13 are spliced, the outer contours of the two adjacent screens 10 are flush.

[0031] The first splicing part 12 and the second splicing part 13 can have various mating structures. In this embodiment, the first splicing part 12 preferably includes a protrusion 121. In this embodiment, a protrusion 121 is provided on one side 11 of a curtain 10. The protrusion 121 occupies 1%-15% of the curtain 10. The protrusion 121 is coplanar with the side 11 and protrudes from the side 11.

[0032] In this preferred embodiment, the second splicing part 13 includes a groove 131 corresponding to the protrusion 121, and a groove 131 is provided on one side 11 of another curtain 10 adjacent to one curtain 10.

[0033] Specifically, the protrusion 121 is inserted into the groove 131 and is glued and fixed to the groove 131.

[0034] As attached Figure 2 , 3 As shown, in this embodiment, a protrusion 121 on a screen 10 is disposed away from the edge of the side panel 11, and the protrusion 121 is located in the middle of the side panel 11. In this embodiment, the center line of the protrusion 121 coincides with the center line of the side panel 11. However, in other embodiments, the center lines may deviate slightly, meaning the protrusion 121 may be disposed away from the exact center of the side panel 11. The protrusion 121 includes a pair of symmetrically arranged first adhesive surfaces 122, and an end face 124 connected to the pair of first adhesive surfaces 122. In this embodiment, the end face 124 is a plane, parallel to the side panel 11. Of course, as shown in the attached diagram… Figure 4As shown, the end face 124 can also be an arc surface. The arc surface structure of the end face 124 can further increase the contact area between the end of the protrusion 121 and the bottom of the groove 131, which is conducive to applying more glue 60.

[0035] A groove 131 on another curtain 10 adjacent to one curtain 10 is located in the middle of the side surface 11 of the curtain, and the groove 131 is positioned corresponding to the protrusion 121. The groove 131 has two sidewalls that correspond one-to-one with the first bonding surface 122, and the groove 131 forms a U-shaped notch. The protrusion 121 is inserted into the groove 131, and the first bonding surface 122 is bonded to the inner wall of the groove 131 with adhesive 60, thus fixing the protrusion 121 to the groove 131. In addition to applying adhesive 60 to the first bonding surface 122, adhesive 60 can also be applied to the opposite side surfaces 11 and end faces 124 of the two adjacent curtains 10.

[0036] It should be noted that Adhesive 60 can be polyvinyl alcohol, epoxy resin, UV adhesive, etc. The material of Adhesive 60 can be selected according to actual needs, as long as it can play a bonding role.

[0037] As attached Figure 5 As shown, the protrusion 121 can be located either in the middle of the side surface 11 of the screen or at the edge of the side surface 11 of the screen. In this embodiment, the protrusion 121 is preferably located on the first side of the side surface of the screen 10. The protrusion 121 includes a second adhesive surface 123, and the groove 131 is located on the second side of the side surface of the screen 10. The second adhesive surface 123 is bonded to the inner wall of the groove 131.

[0038] Specifically, the incident direction of the incident beam can be from the first side of the side of the screen 10 to the second side of the side of the screen 10.

[0039] For example, the first side of the screen 10 can be the side of the screen 10 closer to the incident light source, and the second side of the screen 10 can be the side of the screen 10 away from the incident light source. The incident light source here can be the light source from which the projected image is projected onto the screen 10, such as a projector or a projector.

[0040] Alternatively, for example, the first side of the screen 10 can be the side closer to the viewer, and the second side of the screen 10 can be the side farther away from the viewer. It should be noted that the viewer can refer to the person watching the movie during the screening, in which case the viewer and the light source projected onto the screen are located on the same side of the screen 10.

[0041] It should be noted that the first side and the second side of the screen 10 are in a relative positional relationship, and their positions can be interchanged according to actual needs.

[0042] In this preferred embodiment, the protrusion 121 is disposed on the edge of the side surface 11, located on the side surface 11 of the screen near the incident light source, and the protrusion 121 and the side surface 11 form an L-shaped structure. The protrusion 121 includes a second adhesive surface 123. In this embodiment, the second adhesive surface 123 is perpendicular to the side surface 11. In other embodiments, the second adhesive surface 123 may also be disposed at an angle to the side surface 11.

[0043] It should be noted that the protrusion 121 is located on the side of the screen 11 near the incident light source. That is, the protrusion 121 can be located in the area where the side 11 is located. The plane where the protrusion 121 is located is the same as or close to the plane where the side 11 is located. On the other hand, it can be considered that the side 11 refers to the area with a certain depth based on the plane.

[0044] Correspondingly, the groove 131 is located on the side of the screen 11 away from the incident light source. The groove 131 has a sidewall that contacts the protrusion 121, and the notch formed by the groove 131 corresponds to the protrusion 121. The protrusion 121 is inserted into the groove 131 and fills the notch. The second adhesive surface 123 is bonded to the inner wall of the groove 131 with adhesive 60, and the protrusion 121 and the groove 131 are glued and fixed. In addition to applying adhesive 60 to the second adhesive surface 123, adhesive 60 can also be applied to the sidewalls 11 where two adjacent screens 10 are joined.

[0045] As attached Figure 6 , 7 As shown, to increase the contact area between two adjacent screens 10, the first splicing portion 12 may also include multiple protrusions 121. In this preferred embodiment, the first splicing portion 12 includes multiple protrusions 121 evenly distributed along the width direction of the screen 10. In this preferred embodiment, a screen 10 has multiple protrusions 121 on one side 11. Each protrusion 121 includes a third bonding surface 125 arranged at an angle to the side 11. In this embodiment, the cross-section of the protrusion 121 is triangular, with two connected third bonding surfaces 125. The third bonding surfaces 125 of multiple protrusions 121 combine to form a wavy or sawtooth surface. The second splicing part 13 includes a plurality of grooves 131 that match the protrusions 121. Another curtain 10 adjacent to a curtain 10 is provided with a plurality of grooves 131. The plurality of grooves 131 are arranged one-to-one with the plurality of protrusions 121. The grooves 131 have a plurality of sidewalls that correspond one-to-one with the third bonding surface 125. The protrusions 121 are inserted into the grooves 131 one by one. The third bonding surface 125 is bonded to the inner wall of the grooves 131 by adhesive 60. The protrusions 121 and the grooves 131 are glued and fixed.

[0046] Traditional splicing methods only apply adhesive 60 to the sides of the screen 10. To reduce the impact of the splicing on the viewing experience, the distance between two adjacent screens 10 is minimized during splicing, resulting in a thin layer of adhesive 60 applied between them. Furthermore, the small area of ​​the sides 11 of the screens 10 also limits the amount of adhesive 60 that can be applied, leading to insufficient adhesion and affecting the splicing effect. This embodiment incorporates a splicing structure between adjacent screens 10. This structure increases the contact area between the adjacent screens 10, allowing for the application of more adhesive 60 and improving the adhesion between the screens 10, effectively preventing them from detaching. In addition, in this embodiment, the adhesive 60 is primarily applied to the splicing contact surface; the sides 11 of the screens 10 may be left untreated or only lightly treated with adhesive 60. This minimizes the distance between adjacent screens 10 during splicing, further reducing the impact of the splicing on the viewing experience. It should be noted that the above embodiment only sets the splicing structure on one side 11 of the curtain 10. In other embodiments, splicing structures can also be set on multiple sides 11 according to size requirements.

[0047] As attached Figure 1 , 2 As shown, a first strip 20 and a second strip 30 are symmetrically arranged on both sides of the screen 10 to increase the adhesion of the screen 10. In this embodiment, both the first strip 20 and the second strip 30 are flat structures made of plastic materials such as PVC and polypropylene.

[0048] The first strip 20 is fixed to the side of the screen 10 closest to the incident light source. Preferably, in this embodiment, the first strip 20 is adhered to the screen 10, covering the joint between two adjacent screens 10. To avoid affecting the projection effect of the screen 10, the first strip 20 in this embodiment is transparent, allowing the incident light beam to pass through and illuminate the screen 10. The length of the first strip 20 in this embodiment corresponds to the length of the screen 10. When the first strip 20 is adhered to the screen 10, its upper and lower ends are flush with the upper and lower ends of the screen 10, respectively. The second strip 30 is fixed to the side of the screen 10 furthest from the incident light source. Preferably, in this embodiment, the second strip 30 is adhered to the screen 10, covering the joint between two adjacent screens 10. The length of the second strip 30 in this embodiment corresponds to the length of the screen 10. When the second strip 30 is pasted onto the screen 10, its upper and lower ends are flush with the upper and lower ends of the screen 10, respectively. Adhesive 60 applied between two adjacent screens 10 can be used to bond the first strip 20 and the second strip 30. The first strip 20 and the second strip 30 not only protect the adhesive 60 but also increase the stress between the two adjacent screens 10. In this embodiment, the first strip 20 and the second strip 30 have the same area, and their pasting positions overlap along the direction of the light beam. Of course, in other embodiments, the first strip 20 and the second strip 30 may have different areas, or they may be pasted in a staggered manner along the direction of the light beam.

[0049] It should be noted that in this embodiment, the first strip 20 and the second strip 30 are pasted at the joint of two adjacent curtains 10. Figure 1 , 2 Only one matching structure of the first splicing part 12 and the second splicing part 13 is shown. Other matching structures of the first splicing part 12 and the second splicing part 13 disclosed above can also be achieved by pasting the first strip 20 and the second strip 30 at the splicing point of two adjacent curtains 10.

[0050] As attached Figure 8The diagram shows the structure of the screen provided in Embodiment 2 of the present invention. Embodiment 2 is similar in structure to Embodiment 1, with the main difference being the addition of a third strip 40. In this embodiment, the edge of the first strip 20 is recessed relative to the edge of the screen 10, and the surface of the first strip 20, its edge surface, and the screen 10 extend beyond the surface of the first strip 20 to form a stepped contour. Although the first strip 20 is transparent, its surface protrudes beyond the surface of the screen 10, and its edge is still perceptible to the viewer. To eliminate the visual impact caused by the edge of the first strip 20, the preferred structure of the screen in this embodiment further includes at least one third strip 40. A portion of the third strip 40 is fixed to the first strip 20, and another portion is fixed to the screen 10. Preferably, the third strip 40 is connected to the first strip 20 and the screen 10 by adhesive. The third strip 40 is a transparent strip, or it may include reflective particles for diffuse reflection of incident light. When the projector projects an image onto the screen, part of the incident light beam shines on the third strip 40. The third strip 40 reflects the incident light through reflective particles, further enhancing the diffuse reflection of the incident light.

[0051] Since the upper and lower ends of the first strip 20 in this embodiment are flush with the upper and lower ends of the screen 10, respectively, it will not cause visual impact. Only a third strip 40 needs to be provided on the side of the first strip 20. In this preferred embodiment, the screen structure includes a pair of third strips 40, symmetrically arranged on both sides of the first strip 20. The length of the third strip 40 in this embodiment corresponds to the side of the first strip 20. The third strip 40 covers the first strip 20, providing a smooth transition between the surface of the first strip 20 and the surface of the screen 10. To facilitate the attachment of the third strip 40 to the first strip 20, the outer surface of the third strip 40 in this embodiment has a groove that matches the end of the first strip 20. The groove of the third strip 40 wraps around the outside of the end of the first strip 20, and the groove of the third strip 40 is attached to the end of the first strip 20.

[0052] When the third strip 40 is attached to the first strip 20 and the screen 10, its upper and lower ends are flush with the upper and lower ends of the screen 10, respectively. The protruding edge of the first strip 20 is hidden within the third strip 40, achieving a smooth transition between the edge of the first strip 20 and the screen 10, reducing the visual impact caused by the edge of the first strip 20. The third strips 40, located on both sides of the first strip 20, not only reduce the visual impact caused by the edge of the first strip 20 but also reinforce the adhesion between the first strip 20 and the screen 10, further enhancing the bonding effect on the screen 10.

[0053] As attached Figure 9 , 10The diagram shows the structure of the screen provided in Embodiment 3 of the present invention. Embodiment 3 is similar in structure to Embodiment 1, with the main difference being the addition of a protective cover 50. Because the second strip 30 is relatively thin, to protect and reinforce it, the preferred screen structure in this embodiment further includes a protective cover 50 with an inner cavity. The preferred protective cover 50 in this embodiment has a rectangular structure, with an opening on its shell. The size of the opening is larger than the size of the second strip 30. The opening of the protective cover 50 is disposed on the second strip 30, which is located within the inner cavity. The protective cover 50 is fixed to the side of the screen 10 closest to the light source. In this preferred embodiment, the protective cover 50 is pasted onto the screen 10, and the screen 10 closes the opening of the protective cover 50. In this embodiment, the length of the second strip 30 is less than the height of the screen 10, and the length of the protective cover 50 corresponds to the length of the screen 10. When the protective cover 50 is pasted onto the screen 10, the upper and lower ends of the protective cover 50 are flush with the upper and lower ends of the screen 10, respectively. In this embodiment, the second strip 30 is placed in the inner cavity of the protective cover 50, which can effectively protect the second strip 30. In addition, the protective cover 50 is also pasted on the screen 10, which further enhances the adhesion to the screen 10.

[0054] In addition to being fixed to the screen 10, the protective cover 50 can also be bonded to the second strip 30. In this preferred embodiment, the protective cover 50 is provided with a through hole 51 for injecting glue 60 into the inner cavity. The second strip 30 is bonded to the inner wall of the protective cover 50 through the glue 60. An glue channel 31 is provided inside the second strip 30. One end of the glue channel 31 communicates with the inner cavity of the protective cover 50. In this embodiment, one end of the glue channel 31 is located below the through hole 51 and is coaxial with the through hole 51. The other end of the glue channel 31 communicates with the screen 10. The glue channel 31 can be L-shaped or arc-shaped. The glue 60 injected into the protective cover 50 flows through the glue channel 31 of the second strip 30 to the joint between the second strip 30 and the screen 10, injecting more glue into the joint to facilitate the bonding and fixation of the second strip 30 and the screen 10.

[0055] In actual installation, firstly, two adjacent screens 10 are glued and fixed at the joint. Next, the first strip 20 and the second strip 30 are respectively placed over the joint of the two adjacent screens 10. The first strip 20 is glued to the side of the screen 10 closest to the incident light source using glue 60 at the joint, and the second strip 30 is glued to the side of the screen 10 away from the incident light source using glue 60 at the joint. Then, the opening of the protective cover 50 is placed on the second strip 30, and the protective cover 50 is glued to the screen 10. Finally, glue 60 is injected into the through hole 51 of the protective cover 50. During the injection of glue 60, some glue 60 flows through the glue channel 31 of the second strip 30 to the joint between the second strip 30 and the screen 10, making the adhesion between the second strip 30 and the screen 10 more stable. After the glue 60 fills the entire inner cavity, the second strip 30 is glued to the inner wall of the protective cover 50.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
