Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a spliced ​​screen and a display device. Background Art

[0002] With the rapid development of science and technology, we will see more and more technological products in our daily lives, including outdoor display devices, such as LED screens, LCD screens, etc. Traditional LCDs are not only low-cost but also high-resolution, but as a spliced ​​screen, they cannot eliminate the seams, which affects the visual effect. Utility Model Content

[0003] In order to solve the problem of the splicing gap of the splicing screen affecting the visual effect, the current method of splicing LED light strips with LCD screens is to use LED light strips to eliminate the splicing gap, which can achieve a zero splicing effect. However, because the LED light strips are attached to the splicing unit, the height of the LED light strips is higher than the splicing unit, and a height difference is formed between the LED light strips and the splicing unit, which affects the overall visual effect of the splicing screen.

[0004] The present application provides a spliced ​​screen and a display device, which, by providing a light-transmitting cover plate, can eliminate the splicing gaps between adjacent unit screens through LED light strips while avoiding the uneven display surface of the spliced ​​screen, thereby improving the overall visual effect of the spliced ​​screen.

[0005] On the one hand, the present application provides a spliced ​​screen, including:

[0006] A splicing unit screen, wherein the splicing unit screen comprises a plurality of unit screens, and a splicing gap is provided between adjacent unit screens;

[0007] An LED light bar, wherein the LED light bar is arranged on the splicing gap;

[0008] A light-transmitting cover plate is arranged above the splicing unit screen.

[0009] By arranging a translucent cover plate on the splicing unit screen, the splicing gap between adjacent unit screens can be eliminated by LED light strips while avoiding the unevenness of the display surface of the splicing screen, thereby avoiding the technical problem of height difference between the LED light strip and the splicing unit, which affects the overall visual effect of the splicing screen, and increasing the overall flatness of the splicing screen to enhance the visual effect.

[0010] In a possible implementation of the present application, the splicing screen further includes a supporting connection member, and the supporting connection member is provided between the light-transmitting cover plate and the splicing unit screen.

[0011] By providing a supporting connection piece, the support and limitation of the light-transmitting cover plate is achieved to ensure the stability of the installation of the light-transmitting cover plate. At the same time, the light-transmitting cover plate can be provided so that there is a certain interval between the light-transmitting cover plate and the splicing unit screen, thereby preventing the impact force from directly acting on the splicing unit screen and causing damage when the light-transmitting cover plate is impacted by an external force, thereby achieving protection for the splicing unit screen.

[0012] In a possible implementation of the present application, the height of the supporting connector relative to the splicing unit screen is not lower than the height of the LED light bar relative to the splicing unit screen; and the supporting connector is provided at the edge of the splicing unit screen.

[0013] By setting the height of the supporting connection piece relative to the splicing unit screen to be not lower than the height of the LED light bar relative to the splicing unit screen, the setting of the light-transmitting cover plate is prevented from being restricted by the height of the LED light bar. By setting the supporting connection piece at the edge of the splicing unit screen, the setting of the supporting connection piece is prevented from affecting the display of the LED light bar and the splicing unit screen.

[0014] In a possible implementation of the present application, the supporting connector is in the shape of a U-shaped letter "U".

[0015] By arranging the supporting connection member to be in the shape of a Chinese character “U”, the supporting stability of the supporting connection member is ensured, and when the supporting connection member supports the transparent cover plate, the unstable support of the transparent cover plate caused by uneven force is avoided.

[0016] In a possible implementation of the present application, a first adhesive layer is provided at one end of the supporting connection member facing the light-transmitting cover plate, and a second adhesive layer is provided at one end of the supporting connection member facing the splicing unit screen.

[0017] The installation and positioning of the glass cover plate are limited by providing the first adhesive layer and the second adhesive layer, and the structure is simple.

[0018] In a possible implementation of the present application, the light-transmitting cover plate is a glass cover plate.

[0019] In a possible implementation of the present application, the supporting connector is made of a transparent material.

[0020] By setting the supporting connection member to be made of a transparent material, it is possible to avoid blocking and affecting the display of the splicing unit screen.

[0021] In a possible implementation of the present application, the light-transmitting cover plate includes a first cover plate area and a second cover plate area, the first cover plate area is arranged directly above the splicing unit screen, and the second cover plate area is arranged directly above the LED light strip, the thickness of the second cover plate area is less than the thickness of the first cover plate area, and a side of the second cover plate area facing the LED light strip forms a groove with the first cover plate area, the spacing between the first cover plate area and the splicing unit screen is equal to the spacing between the second cover plate area and the LED light strip, and the refractive index of the first cover plate area is the same as the refractive index of the second cover plate area.

[0022] By setting the translucent cover plate to include a first cover plate area and a second cover plate area with different thicknesses, and due to the different thicknesses, a groove is formed with the first cover plate area on a side of the second cover plate area facing the LED light strip, thereby increasing the distance between the LED light strip and the second cover plate area, and making the distance between the first cover plate area and the splicing unit screen equal to the distance between the second cover plate area and the LED light strip, thereby avoiding visual deviation caused by different refraction paths due to the gap between the LED light strip and the translucent cover plate being different from the gap between the splicing unit screen and the translucent cover plate, and setting the refractive index of the first cover plate area to be the same as the refractive index of the second cover plate area, thereby further avoiding visual deviation caused by different refractive indices.

[0023] In a possible implementation of the present application, a light-transmitting cover plate is disposed directly above the splicing unit screen and a clearance opening is provided at a position corresponding to the position of the LED light strip, the LED light strip is disposed in the clearance opening, and the LED light strip is flush with the light-transmitting cover plate.

[0024] By setting an avoidance opening for setting the LED light bar at the position of the light-transmitting cover plate corresponding to the LED light bar, and setting the LED light bar flush with the light-transmitting cover plate, the problem of the height difference between the LED light bar and the splicing unit caused by the LED light bar being higher than the splicing unit can be solved, and the disadvantage of increasing the overall thickness of the splicing screen by adding the light-transmitting cover plate can be avoided.

[0025] In a possible implementation of the present application, the splicing screen further includes a limiting member, the limiting member is disposed around the splicing unit screen, and the transparent cover plate is covered on the top of the limiting member.

[0026] By setting the limiting member, the splicing unit screen can be protected and the installation of the light-transmitting cover plate can be realized at the same time, and the distance between the light-transmitting cover plate and the splicing unit screen can be adjusted by adjusting the height of the limiting member, making the installation of the light-transmitting cover plate more flexible and more versatile, and the external force received by the cover plate is decomposed by the limiting member and will not act on the splicing unit screen, thereby realizing protection of the splicing unit screen.

[0027] In a possible implementation of the present application, the supporting connector is a hollow structure.

[0028] By hollowing out the supporting connector, the overall mass is reduced, and the light blocking by the supporting connector when viewed from the side is reduced, thereby improving the display effect.

[0029] In a possible implementation of the present application, the supporting connector includes supporting blocks arranged at multiple intervals.

[0030] By providing a supporting connection member including supporting blocks arranged at multiple intervals, the overall mass is reduced, and the light blocking by the supporting connection member when viewed from the side is reduced, thereby improving the display effect.

[0036] A first adhesive layer is disposed on one end of the supporting connection member facing the light-transmitting cover plate, and a second adhesive layer is disposed on one end of the supporting connection member facing the splicing unit screen.

[0037] In a possible implementation of the present application, the light-transmitting cover plate is arranged directly above the splicing unit screen and a avoidance opening is provided at a position corresponding to the position of the LED light strip, the LED light strip is arranged in the avoidance opening, and the LED light strip is flush with the light-transmitting cover plate.

[0038] In a possible implementation of the present application, the splicing screen further includes a limiting member, the limiting member is disposed around the splicing unit screen, and the transparent cover plate is covered on the top of the limiting member.

[0039] In a possible implementation of the present application, the height of the supporting connector relative to the splicing unit screen is not lower than the height of the LED light bar relative to the splicing unit screen, and the supporting connector is provided at the edge of the splicing unit screen.

[0040] In a possible implementation of the present application, the supporting connector is in the shape of a U-shaped letter "U".

[0041] In a possible implementation of the present application, the light-transmitting cover plate includes a first cover plate area and a second cover plate area, the first cover plate area is arranged directly above the splicing unit screen, and the second cover plate area is arranged directly above the LED light strip, the thickness of the second cover plate area is less than the thickness of the first cover plate area, and a side of the second cover plate area facing the LED light strip forms a groove with the first cover plate area, the spacing between the first cover plate area and the splicing unit screen is equal to the spacing between the second cover plate area and the LED light strip, and the refractive index of the first cover plate area is the same as the refractive index of the second cover plate area.

[0042] In a possible implementation of the present application, the supporting connector is a hollow structure.

[0043] On the other hand, the present application provides a display device, comprising the spliced ​​screen.

[0044] In the present application, a light-transmitting cover plate is arranged on the splicing unit screen, so as to eliminate the splicing gap between adjacent unit screens through LED light strips while avoiding the uneven display surface of the splicing screen, thereby avoiding the technical problem of forming a height difference between the LED light strip and the splicing unit, affecting the overall visual effect of the splicing screen, increasing the overall flatness of the splicing screen and improving the visual effect.

[0055] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any person skilled in the art to implement and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the invention can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0056] The implementation scheme of the present application is aimed at the problem in the prior art that when an LED screen and a liquid crystal screen are spliced, because the LED light bar is attached to the splicing unit, the height of the LED light bar is higher than the splicing unit, and a height difference is formed between the LED light bar and the splicing unit, which affects the overall visual effect of the splicing screen. The implementation scheme of the present application is used to solve this technical problem.

[0057] See also Figure 1 The present application provides a splicing screen, comprising: a splicing unit screen, an LED light bar 2 and a translucent cover plate 3, wherein the splicing unit screen comprises a plurality of unit screens 10, and a splicing gap 11 is provided between adjacent unit screens 10; the LED light bar 2 is arranged on the splicing gap 11; and the translucent cover plate 3 is arranged above the splicing unit screen.

[0058] In the embodiment of the present application, a splicing screen is provided. By arranging a transparent cover plate 3 on the splicing unit screen, the splicing gap 11 between adjacent unit screens 10 is eliminated by the LED light bar 2, and at the same time, the unevenness of the display surface of the splicing screen is avoided, thereby avoiding the technical problem of forming a height difference between the LED light bar 2 and the splicing unit, which affects the overall visual effect of the splicing screen, increasing the overall flatness of the splicing screen, and improving the visual effect.

[0059] It can be understood that in order to ensure display, the light-emitting surface of the LED light strip 2 and the light-emitting surface of the splicing unit screen are located on the same surface, that is, in this embodiment, the light-emitting surface of the LED light strip 2 is the side facing the light-transmitting cover plate 3, and the light-emitting surface (display surface) of the splicing unit screen is the side facing the light-transmitting cover plate 3. It can be understood by technicians in the field that by providing the light-transmitting cover plate 3, while achieving the smooth adjustment of the light-emitting surface, it will not affect the light-emitting of the splicing unit screen and the LED light strip 2. Among them, the light-transmitting cover plate 3 can be a glass cover plate, a PE cover plate, etc., and this application does not make any specific limitations.

[0060] It is understandable that the spliced ​​unit screen can be a liquid crystal display LCD screen, OLED screen, etc. The number of unit screens 10 included in the spliced ​​unit screen can be designed according to the size of the spliced ​​unit screen and the size of each unit screen 10 as needed, and the size of the unit screen 10 is not specifically limited in this application. The sizes of the unit screens 10 in the spliced ​​unit screen can be the same or different, and can be adjusted according to design requirements.

[0061] It is understandable that the LED light bar 2 can be a miniLED light bar or a common LED light bar, and the width of the LED light bar 2 can be specifically designed according to the size of the splicing gap 11 between the adjacent unit screens 10. The LED light bar 2 can be installed on the splicing gap 11 through an adhesive layer, and the wires of the LED light bar 2 can be routed through the splicing gap 11.

[0062] It can be understood that the light-transmitting cover plate 3 can be a whole piece, directly arranged above the splicing unit screen and the LED light strip 2, or a avoidance structure, avoidance groove, avoidance opening, etc. can be set corresponding to the LED light strip 2, which is not limited in this application.

[0063] See also Figure 2 In one embodiment of the present application, the light-transmitting cover plate 3 includes a first cover plate area 30 and a second cover plate area 31, the first cover plate area 30 is arranged directly above the splicing unit screen, and the second cover plate area 31 is arranged directly above the LED light strip 2, the thickness of the second cover plate area 31 is less than the thickness of the first cover plate area 30, and the side of the second cover plate area 31 facing the LED light strip 2 forms a groove 32 with the first cover plate area 30, the distance between the first cover plate area 30 and the splicing unit screen is equal to the distance between the second cover plate area 31 and the LED light strip 2, and the refractive index of the first cover plate area 30 is the same as the refractive index of the second cover plate area 31.

[0064] By setting the translucent cover plate to include a first cover plate area 30 and a second cover plate area 31 of different thicknesses, and due to the different thicknesses, a groove 32 is formed between the first cover plate area 30 and the side of the second cover plate area 31 facing the LED light strip, thereby increasing the distance between the LED light strip and the second cover plate area 31, and making the distance between the first cover plate area 30 and the splicing unit screen equal to the distance between the second cover plate area 31 and the LED light strip, thereby avoiding visual deviation caused by different refraction paths due to the gap between the LED light strip and the translucent cover plate being different from the gap between the splicing unit screen and the translucent cover plate, and setting the refractive index of the first cover plate area 30 to be the same as the refractive index of the second cover plate area 31, thereby further avoiding visual deviation caused by different refractive indices.

[0065] It can be understood that the first cover plate area 30 and the second cover plate area 31 can be made of materials with different refractive indices, or they can be made of the same material and material molecules that increase the refractive index are added to the second cover plate to ensure that the refractive index of the first cover plate area 30 and the second cover plate area 31 is the same, and this application does not make any specific limitations.

[0066] Furthermore, the thickness of the second cover plate area 31 is less than the thickness of the first cover plate area 30, and the side of the second cover plate area 31 facing the LED light strip 2 forms a groove 32 with the first cover plate area 30, that is, the first cover plate area 30 is arranged around the second cover plate area 31 to form the groove wall of the groove 32, and the second cover plate area 31 forms the groove bottom of the groove 32, and the groove bottom is arranged facing the LED light strip 2. It can be understood that in some embodiments of the present application, the LED light strip 2 can be arranged in the groove 32 and the second cover plate area 31 is arranged at intervals, that is, the LED light strip 2 is top-emitting (that is, it emits light on the side facing the second cover plate area 31), and will not affect the light output of the first cover plate area 30. By arranging the LED light strip 2 in the groove 32, the interval between the transparent cover plate 3 and the splicing unit screen can be reduced, thereby reducing the interval between the LED light strip 2 and the transparent cover plate 3, thereby reducing the overall thickness of the splicing screen, so that the performance of the splicing screen is better. In some other implementation schemes of the present application, the LED2 light strip may also be disposed below the groove 32 instead of being disposed in the groove 32 , and may be adjusted according to actual application requirements, which is not specifically limited in the present application.

[0067] It is understandable that in the embodiment of the present application, the transparent cover plate 3 may also not be provided with the groove 32, and the light path can be adjusted by setting different refractive indices of the first cover plate area 30 and the second cover plate to avoid affecting the light output of the transparent cover plate 3 and causing visual deviation.

[0068] In some other embodiments of the present application, see Figure 3 , a light-transmitting cover plate 3 is arranged directly above the splicing unit screen and a position corresponding to the LED light bar 2 is provided with a position-avoiding opening 33, the LED light bar 2 is arranged in the position-avoiding opening 33, and the LED light bar 2 is flush with the light-transmitting cover plate 3. By providing a position-avoiding opening 33 for arranging the LED light bar 2 at the position of the light-transmitting cover plate 3 corresponding to the LED light bar 2, and arranging the LED light bar 2 to be flush with the light-transmitting cover plate 3, the problem that the height of the LED light bar 2 is higher than the splicing unit 1, resulting in a height difference between the LED light bar 2 and the splicing unit 1, is solved, while avoiding the disadvantage of increasing the overall thickness of the splicing screen by adding the light-transmitting cover plate 3.

[0069] Among them, the light-transmitting cover plate 3 is arranged directly above the splicing unit screen and an avoidance opening 33 is provided at the position corresponding to the LED light strip 2, that is, the side of the light-transmitting cover plate 3 facing the LED light strip 2 and the side facing away from the LED light strip 2 are connected to form an avoidance opening, and the light-transmitting cover plate 3 is not provided on the LED light strip 2.

[0070] In the implementation scheme of the present application, the splicing screen also includes a supporting connector 4, which is arranged between the translucent cover plate 3 and the splicing unit screen. The translucent cover plate 3 is supported by the supporting connector 4. It can be understood that since the LED light strip 2 itself is very narrow and may be crushed by the translucent cover plate 3, the LED light strip 2 is supported by providing the supporting connector 4, which can prevent the LED light strip 2 from being damaged when subjected to external force, while maintaining the stability of the installation of the translucent cover plate 3.

[0071] Among them, the supporting connector 4 can be a hollow structure or composed of a plurality of support blocks arranged at intervals, which can realize the supporting connection limit while reducing the mass and reducing the light blocking of the supporting connector 4 when viewed from the side, thereby improving the display effect.

[0072] In some other embodiments of the present application, the support connecting member 4 may not be provided. By providing a limiting member around the splicing unit screen, the limiting member is arranged around the splicing unit screen to protect the splicing unit screen, and the light-transmitting cover plate 3 is covered on the top of the limiting member. While protecting the splicing unit screen by providing the limiting member, the installation of the light-transmitting cover plate 3 can be realized. Moreover, by adjusting the height of the limiting member, the distance between the light-transmitting cover plate 3 and the splicing unit screen can be adjusted, making the installation of the light-transmitting cover plate 3 more flexible and more versatile. In addition, the external force acting on the light-transmitting cover plate 3 is decomposed by the limiting member and will not act on the splicing unit screen, so that the splicing unit screen can be protected. It can be understood that the length and width of the orthographic projection of the light-transmitting cover plate 3 are greater than those of the splicing unit screen.

[0073] In some other embodiments of the present application, if the light-transmitting cover plate 3 is arranged directly above the splicing unit screen and an avoidance opening 33 is provided corresponding to the position of the LED light bar 2, the manufacturing support connecting member 4 may not be provided, and the light-transmitting cover plate 3 can be directly covered on the splicing unit screen.

[0074] In this embodiment, the height of the support connecting member 4 relative to the splicing unit screen is not lower than the height of the LED light bar 2 relative to the splicing unit screen. That is, the height of the support connecting member 4 relative to the splicing unit screen can be higher than the height of the LED light bar 2 relative to the splicing unit screen, or can be equal to the height of the LED light bar 2 relative to the splicing unit screen.

[0075] It can be understood that the support connecting member 4 is mainly used to support the light-transmitting cover plate 3. The support member can be any number of support bars, any number of support blocks and other structures on the premise that this function can be realized. Specifically, the present application does not make any limitations. Further, the support structure can be arranged at the edge, diagonal line, etc. of the splicing unit screen. It can be understood that if the support structure is arranged in the light-emitting area / display area of the splicing unit screen, the support structure is made of a light-transmitting material. When the support structure is arranged in the non-display area of the splicing unit screen, the support structure can be made of a light-transmitting material or a non-light-transmitting material. For example, in this embodiment, the splicing unit screen is an LCD liquid crystal display screen. It can be understood that there is a black edge area at the edge of the LCD, that is, the non-display area. The support connecting member 4 is in a shape of a rectangle with a hole in the middle, and the support connecting member 4 is arranged at the edge of the splicing unit screen, that is, arranged on the black edge area. The support structure can be made of a light-transmitting material or a non-light-transmitting material. In some other embodiments of the present application, the manufacturing structure can also be relatively arranged support bars to ensure the balance and stability of the light-transmitting cover plate 3. Specifically, the present application does not make any limitations.

[0076] It should be noted that there is an inaccuracy in the original text. The description of "所述支撑连接件4为回字形" is not very clear. I translated it as "The support connecting member 4 is in a shape of a rectangle with a hole in the middle" for the sake of understanding, but it is recommended to check and correct the original text for more accurate expression.In the implementation scheme of the present application, a first adhesive layer is provided at one end of the supporting connecting member 4 facing the glass cover plate, and a second adhesive layer is provided at one end of the supporting connecting member 4 facing the splicing unit screen. The first adhesive layer and the second adhesive layer are used to limit the light-transmitting cover plate 3, the splicing unit screen and the supporting structure. It can be understood that the first adhesive layer and the second adhesive layer can be adhesive layers of the same material or different materials, such as waterproof and non-waterproof, and the first adhesive layer and the second adhesive layer can select light-transmitting glue and non-light-transmitting glue according to the setting position of the supporting structure. It can be specifically designed according to actual needs, that is, if the supporting structure is set in the light-emitting area / display area of ​​the splicing unit screen, the first adhesive layer and the second adhesive layer are adhesive layers of light-transmitting material. When the supporting structure is set in the non-display area of ​​the splicing unit screen, the first adhesive layer and the second adhesive layer can be adhesive layers of light-transmitting material or non-light-transmitting material.

[0077] It can be understood that in some other embodiments of the present application, the supporting connector 4 can also be a whole transparent adhesive layer; the first adhesive layer and the second adhesive layer can also be omitted, and the position limitation of the light-transmitting cover plate 3, the splicing unit screen and the supporting structure can be achieved by setting a middle frame structure.

[0078] In the embodiment of the present application, the transparent cover plate 3 is a glass cover plate, and the thickness of the transparent cover plate is 0.25-0.5 mm to avoid the transparent cover plate being too thick and causing the spliced ​​screen to be too thick. For example, 0.5 mm, 0.45 mm, etc. It can be understood that 0.25-0.5 mm is only a preferred value range given in the embodiment of the present application, and is not used as a thickness limit of the transparent cover plate 3 in the present application.

[0079] In the embodiment of the present application, the unit screen 10 is an LCD unit screen 10 including a lower layer of glass, an upper layer of glass, and a liquid crystal display layer disposed between the lower layer of glass and the upper layer of glass.

[0080] The present application provides a splicing screen, which is provided with a transparent cover plate 3 on the splicing unit screen, so as to eliminate the splicing gap 11 between adjacent unit screens 10 through the LED light bar 2, and at the same time avoid the unevenness of the display surface of the splicing screen, thereby avoiding the technical problem of forming a height difference between the LED light bar 2 and the splicing unit, affecting the overall visual effect of the splicing screen, increasing the overall flatness of the splicing screen, and improving the visual effect.
