Description

Technical Field

[0001] The invention belongs to the technical field of OLED screen processing, and particularly relates to a method for reinforcing an OLED screen. Background Art

[0002] When our company was researching its products in the design phase, it was discovered that there were no LCD screens of the required size on the market, and it was very expensive to find a manufacturer to customize an LCD screen of the required size. In order to save costs, it was decided to use OLED folding screens of similar size to replace LCD screen processing and manufacturing.

[0003] However, during the production and development stage, it was found that the folding screen had no support design at the middle bend and the screen itself was made of flexible material. After being processed by conventional gluing process, there was no fixing measures for the folding screen, resulting in deformation during the curing process due to the stress generated by the curing of the glue, resulting in display color difference. At the same time, there was a lack of "reinforcement" measures after the device position on the back of the folding screen gave way, resulting in stress accumulation at this position before the glue was cured, and the folding screen itself deformed to produce display color difference. On this basis, a reinforcement method for OLED screens was proposed. Summary of the invention

[0004] The present invention mainly provides an OLED screen reinforcement method to solve the technical problems raised in the above background technology.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: A method for reinforcing an OLED screen comprises the following steps: Place the reinforcing medium on the marked area on the leveling fixture part 2; Place the leveling fixture part 1 on the sunken surface of the leveling fixture part 2, and self-check the four corners of the leveling fixture part 1 to make sure there is no shaking when pressing; Remove the protective film under the weakly sticky medium and align it with the four corners of the leveling fixture part 1, and self-check that the weakly sticky medium is flat on the leveling fixture part 1 without bulges; After removing the protective film on the weakly sticky medium, place the folding screen on the surface of the weakly sticky medium and self-check that the surface of the folding screen is flat and has no warping; Finally, after applying glue on the surface of the folding screen, let it stand for more than 4 hours, then place the leveling fixture and the folding screen in the oven and take them out when the baking is finished.

[0006] In a preferred embodiment of the present invention, the reinforcing medium is a silica gel foam.

[0007] In a preferred embodiment of the present invention, the weakly viscous medium is an insulating rubber sheet.

[0008] In a preferred embodiment of the present invention, the size of the leveling fixture part 1 is the same as the size of the weakly viscous medium, which is 10 mm larger than the size of the folding screen.

[0009] In a preferred embodiment of the present invention, the size of the leveling fixture part 2 is 20 mm larger than the size of the gasket fixture part 1.

[0010] In a preferred embodiment of the present invention, the size of the reinforcing medium is 3 mm inward of the back side of the folding screen.

[0011] In a preferred embodiment of the present invention, the folding screen is 10 inches or less, the compression deformation of the reinforcing medium is 60±10%, and the hardness of the weakly viscous medium is 20~40Shore A.

[0012] In a preferred embodiment of the present invention, the folding screen is 10-20 inches, the compression deformation of the reinforcing medium is 30±10%, and the hardness of the weakly viscous medium is 40~50Shore A.

[0013] In a preferred embodiment of the present invention, the folding screen is larger than 20 inches, the compression deformation of the reinforcing medium is 4.5±10%, and the hardness of the weakly viscous medium is 50~70Shore A.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention avoids the raised position on the back of the folding screen through the first leveling fixture part's yielding design and weak adhesion design. After adsorption, the second leveling fixture part reinforces the raised position on the back of the folding screen, thereby eliminating the folding screen's own stress before gluing and the glue curing stress during the gluing process, thereby eliminating the problem of product display color difference.

[0015] The leveling fixture provided by the present invention can be designed according to the size of the folding screen to be processed, so as to realize the gluing processing of folding screens of various sizes. At the same time, it is simple to install and operate, and can quickly adapt to design changes. For product architectures with multiple varieties that need to be customized, multiple types of original screens can be selected for processing, which can save a lot of customization costs and improve efficiency. This method can greatly reduce the cost of selecting the original display screen and increase the product design margin, and is suitable for the gluing processing of OLED folding screens of various sizes.
