The embodiment of the disclosure also provides a preparation method of the display screen. Fig. 1 is a flowchart illustrating a method for manufacturing a display screen according to an exemplary embodiment of the present disclosure, where the method includes steps 101 to 102.
In step 101, a protective layer is formed on a side of the polarizer.
In one embodiment, the protective layer may be formed on the side of the polarizer by: the first step is as follows: fixing a group of polaroids by using a fixing device, wherein a plurality of polaroids in the group of polaroids are overlapped; the second step is as follows: forming a protective material on a side of a set of polarizers; the third step: and stripping the group of polaroids with the protective materials, wherein a protective layer is formed on the side surface of each stripped polaroid.
For the first step, various fixing devices are suitable, such as a clamping device, which fixes the object by clamping, and a group of polarizers can be clamped by using the clamping device.
The group of polaroids further comprises a light-in surface and a light-out surface, wherein the light-in surface is the light-in surface of the polaroid positioned at one end in the group of polaroids, and the light-out surface is the light-out surface of the polaroid positioned at the other end in the group of polaroids. The clamping device can be used for clamping the light incoming surface and the light outgoing surface of the group of polaroids.
In the application, can use clamping device centre gripping a set of polaroid substrate, handle and include: and cutting and polishing to obtain a group of polaroids, wherein the side surfaces of the polaroids in the group of polaroids are positioned on the same plane.
A set of polarizer substrates may be processed in a variety of ways, for example, CNC machining a set of polarizers and/or laser cutting a set of polarizers to obtain a set of polarizers of desired dimensions.
CNC machining is generally referred to as 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 a side of a set of polarizers using a coating device.
The coating device is various, 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 curing adhesive and silicone adhesive, the polymer nano material has better performances such as water resistance, corrosion resistance and the like.
There are many suitable polymeric nanomaterials, for example, polymeric nanomaterials may include fluoride. Illustratively, the polymeric nanomaterial may include a fluoropolymer moisture barrier agent in a hydrofluoroether solvent.
In step 102, the polarizer with the protective layer and other screen components are assembled to obtain the display screen.
And after the polaroid with the protective layer formed on the side surface is obtained, combining the polaroid with other screen components to obtain the display screen. The manufactured display screen has various types, such as a liquid crystal display screen, an OLED (Organic Light-Emitting Diode) display screen, a flexible screen, and the like.
Other screen components are understood to mean components of the display screen other than polarizers, such as display panels, cover plates, etc.
The display screen can be manufactured by assembling the polarizer and other screen components based on the combination relationship among different components in the display screen. The process of assembling the polarizer and other screen components to manufacture the display screen may refer to related technologies, and details of the embodiments of the present disclosure are not repeated herein.
Fig. 2 is a schematic view illustrating a process of applying a protective material according to an exemplary embodiment of the present disclosure, in fig. 2, a holding device 1 holds a set of polarizers 2, the side surfaces of the polarizers 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 side surfaces of the set of polarizers 2 by using the coating device 3.
Because the size of the whole side surface of one group of polaroids is larger, a flat and thin protective layer can be formed on the whole side surface with the larger size, so that a flat and thin 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 present 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, 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 called a panel, and the Adhesive layer 7 may be an OCA (optical Clear Adhesive) layer. The polarizer 5 is manufactured through the process shown in fig. 2.
In fig. 3, the protective layer 8 is formed only on the side surface of the polarizer 5, and is not formed on the surface of other components, which does not have adverse effects on the performance and use of other components, and simultaneously saves the usage amount of protective materials and the manufacturing cost of the display screen.
In the related art, after the assembly of the plurality of components of the display screen is completed, in order to prevent the glue reagent from falling onto other components in the falling process of the coating device, the assembled plurality of components are obliquely placed before dispensing so as to enable part of the components to be far away from the coating device, the possibility that the falling glue reagent falls onto other components is reduced, and then the coating device is used for dispensing the side surface of the polarizer.
Fig. 4 is a schematic view showing a process of dispensing in the related art, in fig. 4, a plurality of components for manufacturing an OLED display are assembled and then tilted, and a coating device 10 is used to dispense a side surface of the polarizer 5. The glue layer 9 formed after dispensing is located on the side surfaces of the polarizer 5 and other adjacent components, and has adverse effects on the performance and use of other components.
In the scheme shown in fig. 4, since the dispensing process is performed only on the side surface of a single polarizer in an inclined state, the obtained adhesive layer 9 is prone to have an arc-shaped surface structure, and the adhesive layer 9 is thick, so that it is difficult to obtain a flat and thin adhesive layer.
It should be noted that fig. 2, fig. 3, and fig. 4 are schematic structural diagrams, and do not represent actual dimensions, and the actual dimensions of each component may be set as required.
The embodiment of the disclosure provides a method for preparing a display screen, which comprises the steps of firstly 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 glue reagents fall 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.
