The embodiment of the disclosure also provides a preparation method of the display screen. Fig. 1 is a flowchart illustrating a method of manufacturing a display screen according to an exemplary embodiment of the present disclosure, the method including steps 101 to 102.
In step 101, a protective layer is formed on the side of the polarizer.
In one embodiment, the protective layer may be formed on the side of the polarizer by: a first step of: fixing a group of polaroids by using a fixing device, wherein a plurality of polaroids in the group of polaroids are overlapped; and a second step of: forming a protective material on sides of the set of polarizers; and a third step of: and stripping the group of polaroids with the protective material, wherein a protective layer is formed on the side surface of each stripped polaroid.
For the first step, there are various fixing devices, such as a clamping device, which fixes an object by clamping, and a group of polarizers may be clamped by the clamping device.
The polarizer further comprises a light incident surface and a light emergent surface, wherein the light incident surface is a light incident surface of one polarizer positioned at one end of the polarizer, and the light emergent surface is a light emergent surface of the other polarizer positioned at the other end of the polarizer. The light incident surface and the light emergent surface of a group of polaroids can be clamped by using a clamping device.
In application, a set of polarizer substrates may be clamped using a clamping device, and the set of polarizer substrates may be treated, the treatment comprising: cutting and polishing to obtain a group of polaroids, wherein the side surfaces of the polaroids in the obtained group of polaroids are positioned on the same plane.
A set of polarizer substrates may be treated in a variety of ways, for example, CNC processing of a set of polarizers and/or laser cutting of a set of polarizers to obtain a set of polarizers of a desired size.
CNC machining generally refers to computer numerically controlled precision machining. There are various apparatuses for performing CNC machining, such as a CNC machining lathe, a CNC machining milling machine, a CNC machining boring and milling machine, and the like.
For the second step, a protective material may be formed on the sides of the set of polarizers using a coating device.
There are various coating devices, and for example, the coating device may include a brush for brushing the protective material or a spray valve for spraying the protective material.
The protective material may include a polymeric nanomaterial. Compared with the existing ultraviolet light curing adhesive and silicone adhesive, the waterproof and anti-corrosion performances of the polymer nano material are better.
There are a variety of suitable polymeric nanomaterials, for example, polymeric nanomaterials can include fluorides. Illustratively, the polymeric nanomaterial may include a fluoropolymer moisture barrier agent in a solvent of a hydrofluoroether.
In step 102, the polarizer with the protective layer formed thereon and other screen components are assembled to produce a display screen.
And after obtaining the polaroid with the protective layer formed on the side surface, combining the polaroid with other screen components to obtain the display screen. The display screen is manufactured in various manners, such as a liquid crystal display screen, an OLED (Organic Light-Emitting Diode) display screen, a flexible screen, and the like.
Other screen components may be understood as other components of the display screen than polarizers, such as display panels, cover plates, etc.
The polarizer and other screen components can be assembled based on the combination relation among different components in the display screen to prepare the display screen. The process of assembling the polarizer and other screen components to manufacture the display screen may refer to related technologies, and embodiments of the disclosure are not described herein.
Fig. 2 is a schematic view illustrating a process of coating a protective material according to an exemplary embodiment of the present disclosure, in fig. 2, a clamping device 1 clamps a set of polarizers 2, sides of each polarizer are located on the same plane, a coating device 3 is disposed above the set of polarizers 2, and the protective material is coated on the sides of the set of polarizers 2 using the coating device 3.
Because the whole side surface of one group of polaroids is larger in size, a flat and thinner protective layer can be formed on the whole side surface with larger size, so that a flat and thinner protective layer can be formed on the side surface of each obtained polaroid, and the internal space of the display screen is saved.
Fig. 3 is a schematic structural diagram of a display screen according to an exemplary embodiment of the disclosure, where the display screen shown in fig. 3 is an OLED display screen, and includes a glass cover plate 4, a polarizer 5, and a display panel 6, and an adhesive layer 7 is disposed between the polarizer 5 and the glass cover plate 4, and the polarizer 5 is fixed to the glass cover plate 4 through the adhesive layer 7. The display panel 6 may be referred to as a panel, and the adhesive layer 7 may be an OCA (Optically Clear Adhesive, optical adhesive) layer. The polarizer 5 is manufactured by the process shown in fig. 2.
In fig. 3, the protective layer 8 is formed only on the side of the polarizer 5, not on the surface of other components, and does not adversely affect the performance and use of other components, and meanwhile, the amount of protective material used is reduced, and the manufacturing cost of the display screen is saved.
In the related art, after the assembly of a plurality of components of the display screen is completed, in order to prevent the glue reagent from falling from the coating device and falling onto other components, the assembled plurality of components are obliquely placed before dispensing, so that part of the components are far away from the coating device, the possibility that the falling glue reagent falls onto the other components is reduced, and then the side surface of the polaroid is subjected to dispensing treatment by using the coating device.
Fig. 4 is a schematic view of a process of dispensing treatment in the related art, and in fig. 4, a plurality of components for preparing an OLED display screen are assembled and then placed obliquely, and a side surface of a polarizer 5 is subjected to a dispensing treatment using a coating device 10. The glue layer 9 formed after dispensing is located on the side of the polarizer 5 and other adjacent components, which has a bad influence on the performance and use of the other components.
In the scheme shown in fig. 4, since the dispensing process is performed on only one side of the polarizer in an inclined state, the obtained adhesive layer 9 is easy to have an arc-shaped surface structure, and the adhesive layer 9 is thicker, it is difficult to obtain a smooth and thinner adhesive layer.
It should be noted that, fig. 2, fig. 3 and fig. 4 are all schematic structural diagrams, which do not represent actual dimensions, and the actual dimensions of each component may be set according to needs.
The embodiment of the disclosure provides a preparation method of a display screen, which comprises the steps of forming a protective layer on the side surface of a polaroid, and then preparing the display screen by using the polaroid with the protective layer, so that the problem that a glue reagent falls on the surfaces of other components in the related art is avoided, the quality of the prepared display screen is ensured, and the production yield of the display screen is improved.
