[0050] In the embodiment of the present application, the OLED screen in the explosion-proof OLED display is fixed to the inside of a transparent shell by shadowless adhesive to form an explosion-proof display structure. The structure has a high protection level and a good explosion-proof effect. While meeting the large-size explosion-proof design, it can still achieve a small size and light weight. The OLED screen has low power consumption and low heat generation. At the same time, the OLED screen is wrapped in the transparent shell by shadowless adhesive, which is conducive to quickly conducting the heat generated by the OLED screen to the outside of the transparent shell.

[0056] The OLED screen 1 of this embodiment adopts organic light-emitting diode technology, and its working principle is to achieve display by stimulating organic materials to emit light. Compared with traditional LCD screens, the OLED screen 1 has higher brightness, wider color gamut and higher contrast, and does not require a backlight. Its biggest feature is transparency. It can maintain transparency while displaying content, bringing users a more immersive visual experience. Shadowless glue 6 (UV glue) is different from other colloids.

[0066] In this embodiment, the OLED screen 1 in the explosion-proof OLED display screen is fixed to the inside of the transparent shell 2 by the shadowless adhesive 6 to form an explosion-proof display structure. The structure has a high protection level and a good explosion-proof effect. Under the premise of meeting the large-size explosion-proof design, it can still achieve a small size and light weight. The OLED screen 1 has low power consumption and low heat generation. At the same time, the OLED screen 1 is wrapped in the transparent shell 2 by the shadowless adhesive 6, which is conducive to quickly conducting the heat generated by the OLED screen 1 to the outside of the transparent shell 2. The explosion-proof OLED display screen of this embodiment meets the explosion-proof requirements and can be used in explosive environments. The OLED screen 1 is cast and sealed in the transparent shell 2 using the shadowless adhesive 6 to achieve the explosion-proof requirements. And its strength is increased, making up for its own relatively fragile shortcomings.

[0067] See also Figure 4 , Figure 5 and Figure 7 As shown, the present invention also provides a method for manufacturing an explosion-proof OLED display screen, comprising the following steps:

[0068] S1. The top of the circuit part 8 is fixedly connected to the bottom of the OLED screen 1 (see Figure 5 shown);

[0069] Furthermore, the length of the OLED screen 1 is greater than the length of the circuit portion 8 , and the transverse center axis of the OLED screen 1 coincides with the transverse center axis of the circuit portion 8 .

[0070] S2. The OLED screen 1 is hoisted inside the transparent housing 2, and the position of the OLED screen 1 is adjusted so that the center of gravity of the OLED screen 1 coincides with the center of gravity of the transparent housing 2;

[0071] It should be noted that the transparent housing 2 is an integrally-molded housing.

[0072] The OLED screen 1 of this embodiment adopts organic light-emitting diode technology, and its working principle is to realize display by stimulating organic materials to emit light. Compared with traditional LCD screens, the OLED screen 1 has higher brightness, wider color gamut and higher contrast, and does not require a backlight. Its biggest feature is transparency, which can maintain transparency while displaying content, bringing users a more immersive visual experience.

[0073] In actual application, before executing step S2 , the transparent shell 2 is first inverted on a work platform to facilitate the OLED screen 1 to be hoisted inside the transparent shell 2 .

[0074] S3. Injecting the shadowless glue 6 into the transparent housing 2 to fill the gap between the OLED screen 1 and the transparent housing 2;

[0075] The shadowless glue 6 (UV glue) of this embodiment is different from other colloids. Its material is like water, and it is not easy to generate bubbles during the injection process. The shadowless glue 6 has high bonding strength. Through the destructive test, the plastic body can be broken without debonding. It can be positioned in a few seconds and reach the highest strength in one minute, which greatly improves the work efficiency. It is completely transparent after curing, and the product does not turn yellow or white for a long time.

[0076] In actual application, UV glue is injected between the OLED screen 1 and the transparent housing 2 until the UV glue covers the display area of ​​the OLED screen 1 to ensure the transparency of the display area.

[0077] S4. Using an ultraviolet light source to irradiate the transparent housing 2 until the shadowless adhesive 6 is cured;

[0078] S5. Place the bottom of the transparent shell 2 and the circuit part 8 inside the unit shell, and use potting glue 7 to fill the gap between the bottom of the transparent shell 2 and the circuit part 8 and the unit shell, so that the bottom of the transparent shell 2 and the circuit part 8 are fixed inside the unit shell.

[0079] In this embodiment, see Figure 6 and Fig. 9 As shown, fixing rods are arranged on both sides of the transparent shell 2; the unit housing may include: a front cover 3, a rear cover 4 and a bottom cover 5, and the fixing rods are fixedly connected between the bottom cover 5, the front cover 3 and the rear cover 4 by screws.

[0080] In this embodiment, the method for making an explosion-proof OLED display screen uses a shadowless glue 6 to be poured into the gap between the OLED screen 1 and the transparent shell 2, and uses a potting glue 7 to fill the gap between the bottom of the transparent shell 2 and the circuit part 8 and the unit shell, thereby forming an explosion-proof display structure with a high protection level and good explosion-proof effect. For a large-sized OLED screen 1, the power consumption is low and the heat generation is small. At the same time, the OLED screen 1 is wrapped in the transparent shell 2 by the shadowless glue 6, which is conducive to quickly conducting the heat generated by the OLED screen 1 to the outside of the transparent shell 2, and the heat dissipation speed is fast.

[0081] In a preferred embodiment, step S2 may include the following steps:

[0082] See also Figure 8 and Fig. 9 As shown, the clamp 9 is fixed to the bottom of the OLED screen 1, and the clamp 9 is arranged on both sides of the circuit part 8; the OLED screen 1 is hoisted into the transparent shell 2 by the clamp 9, and the position of the OLED screen 1 is adjusted so that the center of gravity of the OLED screen 1 coincides with the center of gravity of the transparent shell 2.

[0083] Further, step S5 may include: fixing the front cover 3 and the back cover 4 to the bottom ends of the transparent shell 2 respectively, with the circuit part 8 located between the front cover 3 and the back cover 4, removing the clamp 9 placed on the OLED screen 1, and using the potting glue 7 to fill the gap between the circuit part 8 and the front cover 3 and the back cover 4. After the potting glue 7 is cured, fixing the bottom cover 5 between the front cover 3 and the back cover 4 with screws.

[0084] The explosion-proof OLED display manufacturing method of this embodiment adopts a cast-type explosion-proof structure, which can meet the design of large-size display equipment. While meeting the explosion-proof design conditions, it can still be small in size and light in weight; the OLED screen 1 has low power consumption and low heat generation, and the entire screen is wrapped with UV glue, which is conducive to the rapid conduction of the heat generated by it to the transparent shell 2; the cast-type explosion-proof design increases the overall strength of the display screen, has a higher protection level and does not affect its transparent effect; the darker light underground can make up for the shortcoming of the OLED screen 1 displaying black as transparent, providing a new experience for information display and making it more attractive.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
