The following describes a transparent display screen with a glue filling structure according to an embodiment of the present invention with reference to fig. 1 to 3.
According to the utility model discloses encapsulating structure transparent display screen, including first transparent substrate 100, sealant frame 200, transparent stereoplasm template 300, second transparent substrate 400, transparent liquid optical cement 500, LED device 600. A first transparent substrate 100; a sealant frame 200 disposed at an edge of the first transparent substrate 100; the transparent hard template 300 is arranged on the upper surface of the first transparent substrate 100 and positioned in the sealant frame 200, the height of the transparent hard template 300 is less than that of the sealant frame 200, and a through hole 310 is formed in the transparent hard template 300; a second transparent substrate 400 disposed on the upper surface of the sealant frame 200; the second transparent substrate 400, the first transparent substrate 100 and the sealant frame 200 enclose a sealed space, and the sealed space is filled with the transparent liquid optical cement 500; and the LED device 600 is disposed on the upper surface of the first transparent substrate 100 and located in the through hole 310.
Referring to fig. 1 to 3, the sealant frame 200 is disposed at the peripheral edge of the first transparent substrate 100 and is disposed in a square shape. The shape of the sealant frame 200 can be various, and the shape adopted in the common case is the same as that of the display; especially for the irregular screen such as circular, triangle-shaped needs the timely change to the shape of the frame 200 of joint sealant. The first transparent substrate 100 is used to arrange the LED devices 600, and the mounting of the LED devices 600 and the connection with the external driving control board are not separated from the first transparent substrate 100. The size of the transparent hard template 300 is smaller than that of the sealant frame 200, so that the transparent hard template 300 can be placed on the upper surface of the first transparent substrate 100 and can be positioned in the sealant frame 200; meanwhile, the transparent hard template 300 is provided with the through holes 310, and after the transparent hard template 300 is attached to the first transparent substrate 100, the LED devices 600 can be arranged in the through holes 310. The second transparent substrate 400, the first transparent substrate 100 and the sealant frame 200 finally form a closed space, and for a closed space, the sealant can be filled only by reserving a small hole required for sealant filling on one side of the closed space. The LED device 600 is connected to an external driving control board. The connection of the LED device 600 to the external driving control board is generally accomplished by ultra fine wires, transparent electrode channels, or metal grids disposed on the upper surface of the first transparent substrate 100. Since the sealant frame 200 is made of sealant, the sealing effect of the sealed space is not affected by the arrangement of the ultra-fine wires, the transparent electrode channels or the metal grids.
In practical operation, since the holes are formed on the first transparent substrate 100 and the second transparent substrate 400, which is difficult and affects the appearance, a section is usually reserved on one side of the sealant frame 200 before sealing. When the encapsulating, with whole encapsulating structure transparent display screen vertical, then carry out the encapsulating perpendicularly can. In addition, the height of the transparent hard template 300 is less than that of the sealant frame 200, so that a sufficient space can be left between the transparent hard template 300 and the second transparent substrate 400, and the transparent liquid optical cement 500 can be better and faster filled in the whole sealed space during glue filling. During actual industrial production, the first transparent substrate 100, the sealant frame 200, the transparent hard template 300, and the second transparent substrate 400 can be produced in batch, so that the assembly time can be greatly saved, and the sealant filling efficiency can be ensured.
In some embodiments, the transparent hard template 300 and the transparent liquid optical cement 500 are made of materials with the same or similar optical characteristics as possible, so as to ensure that the light emitted from the LED device 600 is more uniform. The transparent hard template 300 and the transparent liquid optical cement 500 may both be made of acrylic materials. Specifically, the transparent hard template 300 may be a PMMA plate, and the transparent liquid optical cement 500 may be a liquid optical potting cement.
According to the utility model discloses encapsulating structure transparent display screen has formed airtight space through second transparent substrate 400, first transparent substrate 100, sealant frame 200, and the mode through directly carrying out the encapsulating can avoid traditional brush to glue the mode and be difficult to control the volume of gluing in airtight space, and then leads to the problem that spills over. Meanwhile, the airtight space can be operated in a glue pouring mode, so that the problem of bubbles caused by insufficient or uneven glue brushing amount is solved. In addition, since the transparent liquid optical adhesive 500 has good fluidity and low viscosity, it is possible to ensure more sufficient filling. Finally, the transparent hard template 300 is used as an intermediate structure, so that the strength of the transparent display screen can be increased, the using amount of the transparent liquid optical cement 500 during glue pouring can be reduced, the cost can be reduced, and the curing time and the deformation amount of the subsequent transparent liquid optical cement 500 during curing can be shortened due to the reduction of the using amount of the transparent liquid optical cement 500.
In some embodiments of the present invention, referring to fig. 3, one side of the sealant frame 200 is provided with a sealant filling hole 210 and a suction hole 220. The glue filling holes 210 are filled with glue, and the air exhaust holes 220 are used for vacuumizing, so that the number of bubbles in the finally formed transparent display screen with the glue filling structure is reduced, and the glue filling speed and efficiency can be increased.
In some embodiments of the present invention, the sealant frame 200 is a double-sided scotch tape. The double-sided transparent adhesive tape has high viscosity and can play a certain structural supporting role. The display area of the transparent display screen can be made larger by adopting the double-sided transparent adhesive tape, and if non-transparent adhesive is adopted, the sealing adhesive frame 200 needs to be sealed into the frame area of the transparent display screen.
In some embodiments of the present invention, there are a plurality of LED devices 600 and the number of through holes 310 are the same; each through hole 310 is used to arrange one LED device 600. When a plurality of LED devices 600 exist at the same time, a mode of placing one LED device 600 in one through hole 310 is usually adopted, so that it is ensured that the usage amount of the transparent liquid optical cement 500 can be further reduced during subsequent potting, and the supporting area of the transparent hard template 300 can be larger. In addition, the size of the through hole 310 is usually designed to be only a little larger than that of the LED device 600, so that the LED device 600 can be ensured to be placed in, and the amount of glue filling can be reduced.
In some embodiments of the present invention, transparent glass is used for both the first transparent substrate 100 and the second transparent substrate 400. 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.
