Description

Technical Field

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

[0002] During the research in the design phase of our product, we found that there were no LCD screens of the required size on the market. It was very expensive to find a manufacturer to customize the LCD screen of the required size. To save costs, we 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 using the conventional gluing process, there was no fixing measure 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 position of the device on the back of the folding screen was given up, 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:

[0006] A method for reinforcing an OLED screen comprises the following steps:

[0007] Place the reinforcing medium on the marked area on the second leveling fixture part;

[0008] 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;

[0009] Remove the protective film under the weakly sticky medium and align it with the four corners of the leveling fixture part 1. Self-check that the weakly sticky medium is flat on the leveling fixture part 1 without bulges;

[0010] After removing the protective film on the surface of the weak adhesive medium, place the folding screen on the surface of the weak adhesive medium and self-check that the folding screen surface is flat and without warping;

[0011] 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 after baking.

[0012] In a preferred embodiment of the present invention, the reinforcing medium is a silica gel foam.

[0013] In a preferred embodiment of the present invention, the weakly viscous medium is an insulating rubber sheet.

[0014] 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.

[0015] In a preferred embodiment of the present invention, the size of the second leveling fixture part is 20 mm larger than the size of the first leveling fixture part.

[0016] In a preferred embodiment of the present invention, the size of the reinforcing medium is 3 mm inward at the yield position on the back of the folding screen.

[0017] 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 20~40 Shore A.

[0018] 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 40-50 Shore A.

[0019] 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 50~70 Shore A.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 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 stress of the folding screen itself before gluing and the stress of glue curing during the gluing process, thereby eliminating the problem of product display color difference.

[0022] The leveling fixture provided by the present invention can be designed according to the size of the folding screen to be processed, and can 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 that require multiple varieties and customization, 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, increase the product design margin, and is suitable for the gluing processing of multi-size OLED folding screens.

[0023] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Reference Figure 1 The present invention provides an OLED screen reinforcement method, comprising the following steps:

[0028] Place the reinforcing medium 3 on the marked area of ​​the leveling fixture part 2;

[0029] 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;

[0030] Remove the protective film under the weak adhesive medium 4 and align it with the four corners of the leveling fixture part 1 and stick it there. Self-check that the weak adhesive medium 4 is flat on the leveling fixture part 1 and there is no bulge.

[0033] The present invention utilizes a stacked design to set the leveling fixture into multiple levels. Through the leveling fixture's yielding design, weak adhesion design, and reinforcement design, the folding screen's own stress and glue curing stress during the bonding process are eliminated, thereby achieving the purpose of eliminating the display color difference after processing.

[0035] In a preferred embodiment of the present invention, the weakly viscous medium 4 is an insulating rubber sheet.

[0042] The present invention provides an OLED screen reinforcement method, which is implemented as follows: after removing the redundant protective parts of the folding screen in advance, place it on the side of the operating table; place the reinforcing medium 3 on the leveling fixture part 2, then assemble the leveling fixture part 1, assemble the weak adhesive medium 4, and finally fix the folding screen on the weak adhesive medium 4.

[0043] Specifically, place the reinforcing medium 3 on the marked area of ​​the leveling fixture part 2; then place the leveling fixture 1 on the sunken surface of the leveling fixture 2, self-check the four corners of the leveling fixture 1, and press it without shaking; then remove the protective film under the weakly sticky medium 4 and align it with the four corners of the leveling fixture 1 and stick it, and self-check that the weakly sticky medium 4 is flat and has no bulges on the leveling fixture part 1; after removing the protective film on the upper surface of the weakly sticky medium 4, place the folding screen on the surface of the weakly sticky medium 4, 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, place the leveling fixture and the folding screen in an oven together, take them out after baking, and proceed to the next process. The specific parameter settings are shown in Table 1 below. Since the glue is not the design point of the present invention, it can be implemented by conventional technical means, such as the two-component glue using optical glue model XRB-9088.
