[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The purpose of this invention is to provide an underwater-capable OLED screen structure to solve the problems existing in the prior art, which can effectively waterproof the OLED screen, enabling the display to adapt to the underwater environment and making it more widely applicable.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1-5 As shown, this embodiment provides an underwater liftable OLED screen structure, including a lifting mechanism and a display screen 1 fixed on the lifting mechanism. The lifting mechanism is located underwater and is used to lift the display screen 1 out of the water. A PCB (Printed Circuit Board) is fixed to the rear surface of the display screen 1, and a waterproof cover 2 is provided on the PCB. The waterproof cover 2 is bonded to the rear surface of the display screen 1 by adhesive. A front glass 3 is attached to the front surface of the display screen 1. The area of ​​the front glass 3 is larger than that of the display screen 1, and the edges of each side of the front glass 3 are located outside the edge of the display screen 1. A rear glass 4 is attached to the rear surface of the display screen 1. Since the waterproof cover 2 is already provided on the rear surface of the display screen 1, the rear glass 4 needs to have a notch to avoid the waterproof cover 2. In this embodiment, part of the edge of the rear glass 4 is attached to the waterproof cover 2, and the other edges of the rear glass 4 are located outside the edge of the display screen 1. The edges of the front glass 3 and the rear glass 4 are arranged opposite each other, and the gap formed between them is filled with a sealing layer formed by potting adhesive. A retaining plate 5 is also provided on the rear surface of the display screen 1. The retaining plate 5 is located outside the waterproof cover 2, and part or all of the retaining plate 5 is located on the surface of the rear glass 4. The gap between the retaining plate 5 and the waterproof cover 2 is filled with a sealing layer formed by potting adhesive. The waterproof cover 2 can prevent adhesive from flowing into the PCB board during potting, and the retaining plate 5 can prevent adhesive from flowing out during potting.

[0029] The location of the retaining plate 5, either partially or entirely, on the surface of the rear glass 4 depends on the position of the PCB board on the display screen 1. If the PCB board is located at a corner of the display screen 1, a corner of the rear glass 4 needs to be cut off to avoid the position of the waterproof cover 2. After installing the rear glass 4, the edge of the cut corner of the rear glass 4 is flush with the outer wall of the waterproof cover 2, while the other edges are located outside the edge of the display screen 1. After installing the retaining plate 5, the bottom of the retaining plate 5 has a stepped structure. Part of it is directly bonded to the rear surface of the display screen 1, close to the edge of the display screen 1, while the other part is bonded to the surface of the rear glass 4. The sealing layer formed by the glue filling in the gap between the retaining plate 5 and the waterproof cover 2 can completely seal the gaps between the retaining plate 5 and the rear glass 4, between the retaining plate 5 and the display screen 1, and between the rear glass 4 and the waterproof cover 2. If the PCB board is not close to a corner of the display screen 1, the rear glass 4 needs to have a closed notch to avoid the position of the waterproof cover 2. The size of the notch should be as close as possible to the size of the waterproof cover 2. In this case, the retaining plate 5 is directly set on the surface of the rear glass 4 and located outside the waterproof cover 2. Simply fill the gap between the enclosure 5 and the waterproof cover 2 with glue.

[0030] This embodiment achieves waterproofing by installing a front glass 3 and a rear glass 4 on the front and rear surfaces of the display screen 1, respectively, and filling the gap between the front glass 3 and the rear glass 4 with adhesive. The waterproof cover 2 and the surrounding plate 5 further waterproof the PCB board and seal the gap between the waterproof cover 2 and the rear glass 4 and / or the display screen 1, enabling the display screen 1 to adapt to underwater environments and broadening its applicability. Furthermore, this embodiment incorporates a lifting mechanism in water to allow the display screen 1 to float or submerge, improving the viewing experience and convenience.

[0031] To improve the heat dissipation of the PCB board, thermally conductive silicone is provided inside the waterproof cover 2 in this embodiment.

[0032] In this embodiment, the lifting mechanism includes a base 6, a lifting section 7, and a lifting platform 8. The base 6 is fixed to the underwater foundation 20 by bolts. The bottom end of the lifting section 7, which has a lifting function, is fixed to the base 6, and the top end is fixed to the lifting platform 8. The display screen 1 is fixed to the lifting platform 8. In this embodiment, the lifting section 7 can be a traditional hydraulic scissor lift. The control box 9, which controls the lifting platform 8 and the display screen 1, is located at the bottom of the display screen 1 and fixed to the front glass 3. The connector of the control box 9 is sealed with glue to prevent water from entering the control box 9. The cables connecting the external power supply and controller to the control box 9, as well as the cables connecting the control box 9 to the display screen 1 and the PCB board, are all located inside the tank chain 10 to prevent the cables of the display screen 1 from getting tangled during the lifting process.

[0033] In this embodiment, the front glass 3 is relatively large, and its bottom extends beyond the display screen 1 and the rear glass 4 by a certain length. An L-shaped fastener 11 is provided at the bottom of the front glass 3. One side of the L-shaped fastener 11 is fixed to the bottom of the front glass 3, and the other side of the L-shaped fastener 11 is fixed to the upper surface of the lifting platform 8.

[0034] To enhance the fixing effect, a reinforcing plate 12 is also connected between the two sides of the L-shaped fastener 11 in this embodiment. In order to prevent the L-shaped fastener 11 from breaking when it is fixed, a buffer silicone layer is also provided between it and the front glass 3.

[0035] This embodiment also includes a housing 13, which is fixed to the foundation 20 and disposed outside the display screen 1 and the lifting mechanism. A cover plate 16 is provided on the top of the housing 13, with an opening 17 on the cover plate 16 for the display screen 1 to move out of the cover plate 16. A brush is provided at the opening 17. The housing 13 is supported by a square tube support frame, which is covered with a stainless steel plate. The housing 13 is used to reduce the impact of water flow, fish, or other objects in the water on the display screen 1, extending the service life of the display screen 1. The brush is disposed around the perimeter of the opening 17, which can prevent fish, shrimp, and impurities from entering the housing 13, and can also clean the front glass 3 and rear glass 4 when the display screen 1 is raised.

[0036] Furthermore, coating technology can be used to endow the surfaces of the front glass 3 and rear glass 4 with hydrophobic, oleophobic, and antibacterial properties. A modified unsaturated prepolymer resin, combined with various functional additives and diluents, is used to prepare a dual-hydrophobic, antibacterial, multifunctional UV-cured coating, enhancing the intrinsic hydrophobic and oleophobic properties of the main resin. Through the synergistic effect of low surface energy resin, dual-hydrophobic additives, antibacterial agents, and hardeners, the coating material on the protective glass surface maintains long-term stable hydrophobic, oleophobic, and antibacterial properties even when submerged underwater for extended periods. Because the coating reduces the adhesion of contaminants, even if the product accumulates contaminants underwater for a long time, they are easily removed by the brush during the next descent. Coating parameters: water contact angle not less than 105 degrees, oil contact angle not less than 55 degrees, cross-cut test ≤ Grade 1 (according to ISO2409-1992 standard), antibacterial activity ≥ 99% (according to GB / T21866-2008).

[0037] In this embodiment, one or more doors 14 are arranged from top to bottom on the surface of the outer casing 13 parallel to the display screen 1. The doors 14 are hinged to the side panels of the outer casing 13 and have handles. The doors 14 are normally locked with bolts 15. When maintenance is required, the bolts 15 are opened and the doors 14 are opened for maintenance. Bolts 15 are used instead of locks to avoid the problem of lock cylinders rusting in water, making them difficult to open. Triangular support frames 18 are respectively provided on the front and rear sides of the outer casing 13. The triangular support frames 18 are fixed to the foundation 20 and located on both sides of the doors 14.

[0038] Furthermore, in this embodiment, guide grooves 19 are vertically arranged on both sides of the outer casing 13 that are perpendicular to the display screen 1. The two side edges of the front glass 3 and the rear glass 4 are respectively located in the two guide grooves 19 to ensure that the display screen 1 can be raised and lowered smoothly.

[0039] Any adaptive changes made according to actual needs are within the scope of protection of this invention.

[0040] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
