Splicing screen and manufacturing method thereof

Abstract

The embodiment of the present application provides a spliced ​​screen and a method for manufacturing the same. The spliced ​​screen includes an LCD display and an LED display connected to each other. The LED display includes a substrate and a reflective layer. The reflective layer is provided on a surface of the substrate facing the LCD display. The spliced ​​screen provided by the embodiment of the present application provides a reflective layer on a surface of the substrate of the LED display facing the LCD display. Since the reflective layer has a light-reflecting effect, it can reflect the portion of the backlight of the LCD display that is directed toward the side of the substrate of the LED display. The reflected light re-enters the LCD display and is finally emitted through the light-emitting surface to realize image display. This solves the problem of light being absorbed in the edge area of ​​the LCD display in the existing spliced ​​screen, resulting in reduced light output brightness in the edge area of ​​the LCD display. This ensures that the display brightness of different areas of the LCD display is uniform and consistent, thereby improving the display effect of the spliced ​​screen.

Description

Technical Field

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

[0002] With the continuous development of the display product market, the size of display products is getting larger and larger. Due to the high production cost of large-size display panels, the market has gradually derived splicing screen products with lower production costs. Since there is a non-display area at the edge of the LCD display, there is a large splicing seam (non-display area) on the splicing screen composed of multiple LCD displays. There is currently a splicing screen that uses LED displays and LCD displays for splicing, which can reduce or eliminate the splicing seam (non-display area) of the splicing screen, thereby improving the viewing angle effect.

[0003] However, since the substrate of the LED display is usually dark or black, the side of the LED display is also dark or black. Since the dark or black material has an absorption effect on light, the part of the backlight of the LCD display that is directed toward the side of the substrate of the LED display is absorbed, which causes the brightness of the light output from the edge area of ​​the LCD display to become darker, resulting in uneven display brightness in different areas of the LCD screen, and thus resulting in poor display effect of the spliced ​​screen. Summary of the Invention

[0004] The embodiment of the present application provides a spliced ​​screen and a manufacturing method thereof, wherein the display brightness of different areas of the LCD display screen in the spliced ​​screen is uniform and consistent, so that the spliced ​​screen has a better display effect.

[0005] In a first aspect, an embodiment of the present application provides a spliced ​​screen, comprising:

[0006] LCD display;

[0007] The LED display screen is connected to the LCD display screen. The LED display screen comprises a substrate and a reflective layer. The reflective layer is arranged on a side surface of the substrate facing the LCD display screen.

[0008] The LED display screen further includes a buffer layer, which is arranged between the substrate and the reflective layer.

[0009] In some embodiments, the buffer layer has an adhesion greater than or equal to 3B.

[0010] In some embodiments, the material of the buffer layer includes organic matter, and the organic matter includes at least one of silicone resin, epoxy resin, and polyurethane.

[0011] In some embodiments, the LED display further includes a protective layer, and the protective layer is disposed on a side of the reflective layer facing away from the substrate.

[0012] In some embodiments, the protective layer has a Shore hardness greater than or equal to D60.

[0013] In some embodiments, the material of the protective layer includes a polymer or a metal oxide, the polymer includes at least one of epoxy resin, silicone resin, and fluoroacrylate, and the metal oxide includes at least one of aluminum oxide and titanium dioxide.

[0014] In a second aspect, an embodiment of the present application provides a method for manufacturing a spliced ​​screen, comprising:

[0015] Providing a substrate, and setting a reflective layer on the side of the substrate to obtain an LED display screen;

[0016] The LED display screen and the LCD display screen are spliced ​​together so that the LCD display screen faces the reflective layer in the LED display screen to obtain a spliced ​​screen.

[0017] In some embodiments, before providing the reflective layer on the side of the substrate, the method for manufacturing the spliced ​​screen further includes: providing a buffer layer on the side of the substrate.

[0018] In some embodiments, after the reflective layer is provided on the side of the substrate, the method for manufacturing the spliced ​​screen further includes: providing a protective layer on a side of the reflective layer facing away from the substrate.

[0019] The spliced ​​screen provided in the embodiment of the present application is provided with a reflective layer on the surface of the side of the substrate of the LED display screen facing the LCD display screen. Since the reflective layer has a reflective effect on light, it can reflect the part of the backlight of the LCD display screen that is directed toward the side of the substrate of the LED display screen. The reflected light re-enters the LCD display screen and finally exits through the light-emitting surface of the LCD display screen to realize image display, thereby solving the problem of light in the edge area of ​​the LCD display screen in the existing spliced ​​screen being absorbed, resulting in reduced light output brightness in the edge area of ​​the LCD display screen, making the display brightness of different areas of the LCD display screen uniform and consistent, thereby improving the display effect of the spliced ​​screen.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0031] See also Figure 1 , Figure 1 This is a schematic diagram of the first structure of a spliced ​​screen provided in an embodiment of the present application. This embodiment of the present application provides a spliced ​​screen 100 comprising an LCD display 120 and an LED display 110 connected to each other. The LED display 110 comprises a substrate 10 and a reflective layer 30. The reflective layer 30 is disposed on a surface of the substrate 10 facing the LCD display 120.

[0032] For example, the substrate 10 may be a glass plate, or the material of the substrate 10 may be a mixture of glass fiber and resin material or BT resin, wherein the BT resin is synthesized from bismaleimide (BMI) and cyanate ester (CE) resin.

[0033] For example, the material of the reflective layer 30 may include metal, and the metal may include aluminum, silver, titanium, and other materials having a mirror reflection effect.

[0034] Please combine Figure 1 The LCD display screen 120 and the LED display screen 110 can be connected via an adhesive layer 130. For example, the adhesive layer 130 can be an optical adhesive (OCA).

[0035] The splicing screen 100 provided in the embodiment of the present application is configured to provide a reflective layer 30 on the surface of the substrate 10 of the LED display screen 110 on the side facing the LCD display screen 120. Since the reflective layer 30 has a reflective effect on light, it can reflect the portion of the backlight of the LCD display screen 120 that is directed toward the side of the substrate 10 of the LED display screen 110. The reflected light re-enters the LCD display screen 120 and is finally emitted through the light-emitting surface of the LCD display screen 120 to realize image display, thereby solving the problem in the existing splicing screen 100 that the light in the edge area of ​​the LCD display screen 120 is absorbed, resulting in a decrease in the light output brightness of the edge area of ​​the LCD display screen 120, so that the display brightness of different areas of the LCD display screen 120 is uniform, thereby improving the display effect of the splicing screen 100.

[0036] Please combine Figure 1 The LED display screen 110 may further include an LED device 50 disposed on the top surface of the substrate 10 .

Figure 1 The difference is that the LED display screen 110 further includes a buffer layer 20, which is disposed between the substrate 10 and the reflective layer 30. It should be noted that the buffer layer 20 can seal residues (such as impurities) on the substrate 10, thereby improving the flatness of the substrate 10 surface and further enhancing the adhesion between the reflective layer 30 and the substrate 10, thereby preventing the reflective layer 30 from falling off the substrate 10.

[0039] Exemplarily, the adhesion of the buffer layer 20 is greater than or equal to 3B. In some embodiments, the adhesion of the buffer layer 20 may be 3B, 4B, or 5B.

[0040] For example, the material of the buffer layer 20 may include organic matter, and the organic matter includes at least one of silicone resin, epoxy resin, and polyurethane.

Figure 1The difference is that the LED display screen 110 further includes a protective layer 40, which is disposed on the side of the reflective layer 30 facing away from the substrate 10. It should be noted that the protective layer 40 has a high Shore hardness and a dense structure, which can protect the reflective layer 30, thereby preventing the reflective layer 30 from falling off the substrate 10 when scratched.

[0042] Exemplarily, the Shore hardness of the protective layer 40 is greater than or equal to D60. In some embodiments, the Shore hardness of the protective layer 40 may be D60 to D80.

[0043] Exemplarily, the material of the protection layer 40 may include a polymer or a metal oxide, the polymer including at least one of epoxy resin, silicone resin, and fluoroacrylate, and the metal oxide including at least one of aluminum oxide (Al 2 O 3 ) and titanium dioxide (TiO 2 ).

[0046] S100, see Figure 6 , providing a substrate 10, setting a reflective layer 30 on the side of the substrate 10, and obtaining an LED display screen 110.

[0050] See also Figure 7 Before providing the reflective layer 30 on the side of the substrate 10, the method for manufacturing the spliced ​​screen may further include: providing a buffer layer 20 on the side of the substrate 10. It should be noted that by providing the buffer layer 20 on the side of the substrate 10, the buffer layer 20 can be used to seal the residue (such as impurities) on the substrate 10, thereby improving the flatness of the surface of the substrate 10, thereby improving the adhesion between the reflective layer 30 and the substrate 10, and preventing the reflective layer 30 from falling off the substrate 10.

[0051] Exemplarily, the adhesion of the buffer layer 20 is greater than or equal to 3B. In some embodiments, the adhesion of the buffer layer 20 may be 3B, 4B, or 5B.

[0052] For example, the material of the buffer layer 20 may include organic matter, and the organic matter includes at least one of silicone resin, epoxy resin, and polyurethane.

[0053] For example, the buffer layer 20 may be prepared by dispensing, inkjet printing, or the like.

It should be noted that by providing the protective layer 40 on the side of the reflective layer 30 facing away from the substrate 10, the protective layer 40 has a high Shore hardness and a dense structure, which can protect the reflective layer 30, thereby preventing the reflective layer 30 from falling off from the substrate 10 when scratched.

[0055] Exemplarily, the Shore hardness of the protective layer 40 is greater than or equal to D60. In some embodiments, the Shore hardness of the protective layer 40 may be D60 to D80.
