Display screens are used In various electronic products, and IML (In Molding Label) injection Molding is increasingly used In various electronic products as people pursue the appearance and the appearance of the electronic products, for example, a cover plate of the outermost layer of the display screen, the IML injection Molding is an injection Molding In which a transparent film and a plastic layer are combined into a whole through an injection mold, that is, the surface of the IML injection Molding is a transparent film, the back surface of the IML injection Molding is a plastic layer, various patterns can be printed on the transparent film, and a pattern ink layer is arranged between the transparent film and the plastic layer, so that the overall appearance is improved, and meanwhile, the pattern ink is prevented from being scratched. However, when the IML cover plate and the display module of the display screen are assembled in a full-lamination mode, the IML cover plate is easy to deform, and the deformation of the IML cover plate is more obvious when the full-lamination high-temperature treatment is carried out, so that the display module can be pulled, and the display screen is caused to display Mura.

Compared with the prior art, the utility model has at least the following advantages:
according to the IML cover plate full-lamination structure for improving the display screen Mura, the cover plate, the first bonding layer, the glass layer, the second bonding layer and the display module are arranged, so that lamination connection can be carried out through the glass layer and the cover plate, deformation of the cover plate can be stressed on glass, stress on the display module is reduced through the glass, and the problem of the display screen Mura can be improved; in addition, through utilizing the high adhesive property and higher hardness of first adhesive linkage and the airtight performance of glass, can effectively prevent the apron outwards release gas under the high temperature, avoid the second adhesive linkage to take place the bubble problem and influence the laminating quality.
Drawings
In order to more clearly illustrate the technical solution of the embodiments of the present utility model, the drawings that are required to be used in the embodiments will be briefly described.
Fig. 1 is a schematic structural diagram of an IML cover plate full-lamination structure for improving Mura of a display screen according to an embodiment of the utility model;
fig. 2 is a schematic diagram of a partial enlarged structure at a position a of the IML cover plate full-bonding structure for improving the display screen Mura in fig. 1.
Detailed Description
In order that the utility model may be readily understood, a more complete description of the utility model will be rendered by reference to the appended drawings.
Referring to fig. 1 and 2, an IML cover plate full-lamination structure 10 for improving Mura of a display screen includes: the cover plate 100, the first bonding layer 200, the glass layer 300, the second bonding layer 400 and the display module 500 are sequentially arranged from top to bottom, wherein the first bonding layer 200 is used for bonding the cover plate 100 and the glass layer 300, and the second bonding layer 400 is used for bonding the glass layer 300 and the display module 500.
It should be noted that, in this embodiment, the cover plate 100 is an IML cover plate, the existing IML cover plate and the display module 500 are generally bonded through a full bonding process, and in the full bonding process, high temperature treatment is required, but the IML injection molding material is not only obviously deformed in a high temperature state, so that the display module 500 is easily subjected to deformation force to finally cause the display screen Mura, but also is also released in a high temperature state, and in the full bonding process, the material of the second bonding layer 400 is required to be relatively soft, that is, the elastic modulus is relatively higher than that of the first bonding layer 200, so that in the high temperature state, the IML cover plate 100 is easy to release gas outwards and enter the second bonding layer 400, and thus, the second bonding layer 400 is easy to generate bubbles to affect the bonding effect;
therefore, by arranging the first adhesive layer 200 and the glass layer 300 between the display module 500 and the IML cover plate 100, and by utilizing the characteristics of the glass layer 300 that the hardness and rigidity are high, the IML cover plate 100 is deformed and stressed on the glass layer 300, so that each component of the display module 500 is not deformed and extruded by the IML cover plate 100, and the display screen Mura is not caused, and thus, the display effect of the display screen can be improved; further, in this embodiment, the first adhesive layer 200 is a first OCA (Optically Clear Adhesive, special adhesive) optical adhesive layer, the OCA optical adhesive is a special adhesive applied in an optical element, and the characteristics of the OCA optical adhesive are slightly different in different adhesive scenes, so that in order to reduce the problem that the IML cover plate 100 easily releases gas at high temperature, the first OCA optical adhesive layer should be selected to use an OCA optical adhesive with a harder texture and higher adhesion strength, and the glass layer 300 can effectively prevent the gas from being released outwards, so that the problem that the second adhesive layer 400 generates bubbles and affects the bonding quality can be reduced. Further, in this embodiment, the second adhesive layer 400 is a second OCA optical adhesive layer, and in general, the second OCA optical adhesive layer is a fully-bonded OCA optical adhesive, and the fully-bonded optical adhesive is often used in the fully-bonded operation of the IML cover 100 and the display module 500, and the fully-bonded OCA is soft, and is not easy to harden or shrink, so that the display module 500 is further prevented from being stressed to generate the display screen Mura phenomenon. Further, the display module 500 may be a conventional TFT (Thin Film Transistor ) display module.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model, which are within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
