The following describes a transparent display screen with a melt adhesive structure according to an embodiment of the present invention with reference to fig. 1 to 3.
According to the utility model discloses glue melting structure transparent display screen, including first transparent substrate 100, first transparent hot melt film 200, second transparent substrate 300, LED device 400. A first transparent hot-melt adhesive sheet 200 disposed on the upper surface of the first transparent substrate 100, wherein a through hole 210 is disposed in the first transparent hot-melt adhesive sheet 200; a second transparent substrate 300 disposed on the upper surface of the first transparent hot-melt adhesive sheet 200; the LED device 400 is disposed on the upper surface of the first transparent substrate 100 and located in the through hole 210; the thickness of the first transparent hot-melt adhesive sheet 200 is greater than the height of the LED device 400.
Referring to fig. 1 to 3, a first transparent substrate 100 and a second transparent substrate 300 sandwich a first transparent hot-melt adhesive sheet 200, the first transparent hot-melt adhesive sheet 200 having a through hole 210 formed therein, the through hole 210 receiving therein an LED device 400 disposed on the first transparent substrate 100. The transparent hot-melt adhesive sheet has the characteristic of melting under the heating and pressurizing states, and has certain fluidity after melting, so that gaps between the first transparent substrate 100 and the second transparent substrate 300 and the LED device 400 can be filled sufficiently, and a good bonding effect can be achieved after cooling. The LED device 400 is connected to an external driving control board. The connection of the LED device 400 to the external driving control board is generally accomplished by ultra-fine wires, transparent electrode channels, or metal grids disposed on the surface of the first transparent substrate 100. Since the transparent hot-melt adhesive sheet itself can be softened after heating, the arrangement of the ultra-fine wires, the transparent electrode channels or the metal grids does not affect the final adhesion degree of the transparent hot-melt adhesive sheet to the upper surface of the first transparent substrate 100.
In actual production, a first transparent hot-melt adhesive sheet 200 with a proper thickness is selected according to the height of the LED device 400, the first transparent hot-melt adhesive sheet 200 with the through hole 210 processed in advance is attached to the upper surface of the first transparent substrate 100, a second transparent substrate 300 is covered on the transparent hot-melt adhesive sheet, the first transparent substrate 100 and the second transparent substrate 300 are attached by heating, gaps around the LED device 400 are filled, and if bubbles are generated, defoaming treatment is performed to complete the whole manufacturing process. Theoretically, the first transparent hot-melt adhesive sheet 200 can be manufactured without the through hole 210, but the presence of the LED device 400 will jack up the first transparent hot-melt adhesive sheet 200, which will eventually increase the air between the first transparent hot-melt adhesive sheet 200 and the first transparent substrate 100, and increase the number of bubbles, and the through hole 210 provided on the first transparent hot-melt adhesive sheet 200 can effectively avoid the problem.
In some embodiments, the first transparent hot-melt adhesive sheet 200 may be made of an acrylic material. Specifically, the first transparent hot-melt adhesive sheet 200 may be ADS-200 of Idahi New Material company.
According to the utility model discloses glue melting structure transparent display screen adopts the transparent hot melt film that is provided with through-hole 210 to replace traditional brush gluey structure, utilizes transparent hot melt film can have certain mobile characteristic under heating, pressurized environment, can cover after first transparent substrate 100 upper surface at transparent hot melt film, just can accomplish transparent display screen's preparation through direct heating, pressurized mode, can save the time of a large amount of brush glues. Meanwhile, the transparent hot melt adhesive sheet is provided with the through holes 210 corresponding to the LED devices 400, so that air between the first transparent substrate 100 and the second transparent substrate 300 can be greatly reduced, and the purpose of reducing bubbles after heating can be achieved. In addition, because what adopt can be batch production have the transparent hot melt film of through-hole 210, consequently can very visual control transparent hot melt film's thickness, and then can reduce the excessive or inhomogeneous problem of overflowing glue that brings because the brush is glued, simultaneously, transparent hot melt film can carry out batch production alone, has simplified the production procedure of transparent display screen, has greatly improved the efficiency of production. Finally, adopt the embodiment of the utility model provides an in the structure for the structure of encapsulating, also no longer need seal with sealed glue peripherally, very big simplification the flow of production, further improve production efficiency.
In some embodiments of the present invention, the above-mentioned transparent display screen with a fuse structure further includes a second transparent hot-melt adhesive sheet 500 disposed between the first transparent hot-melt adhesive sheet 200 and the second transparent substrate 300, and the second transparent hot-melt adhesive sheet 500 completely covers the first transparent hot-melt adhesive sheet 200. The second transparent hot-melt adhesive sheet 500 mainly further avoids the problem that the gap is difficult to fill after the first transparent hot-melt adhesive sheet 200 is melted. The materials of the second transparent hot-melt adhesive sheet 500 and the first transparent hot-melt adhesive sheet 200 need to be consistent.
In some embodiments of the present invention, the first transparent substrate 100, the second transparent substrate 300, and the first transparent hot-melt adhesive sheet 200 have the same shape and size. The three parts adopt the same shape and size, so that the stability of the finally formed product can be ensured to be highest, and the product is more attractive. When the second transparent hot-melt adhesive sheet 500 is used, the shape and size of the second transparent hot-melt adhesive sheet 500 should be as consistent as possible with those of the first transparent hot-melt adhesive sheet 200.
In some embodiments of the present invention, there are a plurality of LED devices 400 and the number of through holes 210 are the same; each through hole 210 is used to accommodate one LED device 400. When a plurality of LED devices 400 exist, the through holes 210 can accommodate the LED devices 400 in a variety of ways, and one LED device 400 can be accommodated in one through hole 210, a plurality of LED devices 400 can be accommodated in the through hole, or an empty through hole 210 can exist. In practical production, the same way of accommodating the LED devices 400 is adopted to cover and reduce the air residue to the greatest extent, so as to reduce the number of subsequent bubbles. Meanwhile, because the gap is reduced, the thickness of the transparent hot melt adhesive sheet is easier to control, and the gap cannot be filled due to overlarge gap and insufficient thickness of the transparent hot melt adhesive sheet.
In some embodiments of the present invention, transparent glass is used for both the first transparent substrate 100 and the second transparent substrate 300. The glass has low price and good light transmittance, and is suitable for mass production and manufacturing.
Although the embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited to the above embodiments, and those skilled in the art can understand that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
