Detailed Description
The present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic view of a polarizer structure according to an embodiment of the present invention. The polaroid structure can be applied to a display panel with an outer pin joint area, and is suitable for the conditions of simultaneously forming a polaroid and covering protective glue of metal wiring in the outer pin joint area. Referring to fig. 1, the polarizer structure 100 includes: a polarizer body 10; the colloid 20 is connected to one side end of the polarizer body 10; a release film 301 attached to the lower surface of the polarizer body 10 and the lower surface of the glue 20; the protective film 302 is attached to the upper surface of the polarizer body 10 and the upper surface of the adhesive 20.
The polarizer body 10 may be any one of the existing polarizers. Can distinguish the upper surface and the lower surface of polaroid structure from type membrane 301, it can play the guard action to polaroid body 10 and colloid 20 to adhere from type membrane 301 at the lower surface of polaroid structure, and has the characteristics of peeling off easily from type membrane 301, when laminating the display panel with the polaroid structure, tear easily from type membrane 301, do not influence the adhesion of colloid, and can not cause the damage to polaroid body 10 and colloid 20. The protective film 302 has high strength and can effectively protect the polarizer body 10 and the adhesive 20. Specifically, when the polarizer structure 100 provided in the embodiment of the present invention is used in a display panel, the display panel may include a display area and an outer lead attachment area, in the polarizer structure 100, the polarizer body 10 is at least located in the display area of the display panel to prevent the display area from reflecting light, and the colloid 20 covers the metal wires in the outer lead attachment area to protect the metal wires.
It is understood that the sizes of the polarizer body 10 and the adhesive 20 may be set according to the size of the display area of the prepared display panel and the size of the area covering the metal traces, which is determined by actual circumstances and is not limited in the embodiment of the present invention.
This embodiment is through integrating polaroid and colloid, connects the colloid in a side of polaroid body, laminates from the type membrane at the lower surface of polaroid body and the lower surface of colloid to and laminate the protection film at the upper surface of polaroid body and the upper surface of colloid, form the polaroid structure. Therefore, when the protective adhesive for covering the metal wiring is formed in the outer pin attaching area of the display substrate, the protective adhesive for the metal wiring can be formed by attaching the polarizer body and the colloid to the display substrate in an aligned manner by only adopting the polarizer structure provided by the embodiment of the invention, so that the colloid covers the metal wiring in the outer pin attaching area, the protective adhesive for the metal wiring is formed, the coating and curing processes of the protective adhesive are simplified, the thickness of the colloid is not greater than that of the polarizer body, namely, the colloid is not too large, and the colloid is not coated on the upper surface of the polarizer body. Therefore, when the polaroid structure is used for preparing a display panel, the process difficulty of forming protective glue in the outer pin attaching area can be reduced, the thickness of the protective glue (colloid) can be ensured, the adhesion reliability of the colloid is improved, the protective glue can be prevented from being coated on the upper surface of the polaroid body, and the subsequent attaching process of the polaroid is ensured; meanwhile, the glue body and the polaroid can be attached at the same time, and the process difficulty of preparing the display panel can be reduced.
Optionally, colloid 20 has a Young's modulus of 3GPa to 10GPa. Specifically, the colloid 20 is used for protecting the metal trace in the outer pin attaching region, and needs to have certain rigidity; meanwhile, when the display panel is bent, the colloid 20 is not broken due to the stress between the substrate and the colloid in the display panel, and the colloid 20 also has certain flexibility. Therefore, the colloid 20 with Young modulus of 3GPa-10GPa is arranged, so that the metal wire can be protected, the bending resistance of the colloid can be improved, and the colloid 20 is prevented from being broken when being bent.
Alternatively, the material of the colloid 20 includes epoxy resin or methyl methacrylate. Specifically, the colloid 20 is used as a protective colloid and can have a certain water and oxygen blocking capability. When the display panel is manufactured, only one layer of organic photoresist is arranged above the metal wires on the substrate, the thickness of the organic photoresist is about 1-3 μm, and the protective effect on the metal wires is limited, so the colloid 20 is mainly arranged to buffer the impact of external force on the metal wires and the attack of water and oxygen on the metal wires when the display panel is bent. Because the curing temperature of the epoxy resin is lower and the inherent polar hydroxyl and ether bond exist in the molecular chain, the epoxy resin has high adhesive force to various substances; the epoxy resin has low shrinkage upon curing and generates small internal stress, which also contributes to improvement of adhesive strength.
Alternatively, on the basis of the above embodiment, the adhesiveness of the lower surface of the colloid 20 is greater than that of the upper surface of the colloid 20. In order to make the adhesive 20 firmly adhere to the outer lead attachment region and prevent the adhesive 20 from falling off from the metal trace when the outer lead attachment region is bent, the adhesiveness of the lower surface of the adhesive 20 is set to be greater than that of the upper surface of the adhesive. The present embodiment can realize that the adhesion of the upper surface of the colloid 20 is lower than that of the lower surface by processing the surface of the colloid 20 and designing the molecular structure of the colloid itself. As an example, a surface modifier for reducing adhesiveness may be doped on the upper surface of the colloid 20, and the surface modifier may be nanoparticles, and the adhesiveness of the upper surface of the colloid 20 may be changed by mixing the nanoparticles on the upper surface of the colloid 20. Therefore, the adhesive property of the lower surface of the colloid 20 is strong, and the colloid can be firmly attached above the metal routing; the adhesiveness of the upper surface of the colloid 20 is low, and the colloid does not adhere to other substances after the protective film 302 is peeled off, so that the display effect of the display surface is affected.
Optionally, the thickness of the adhesive 20 is equal to the thickness of the polarizer body 10. Specifically, in order to make colloid 20 and polaroid structure laminate smoothly to display panel on, set up the thickness with colloid 20 and polaroid body 10's thickness, can guarantee that colloid 20 and polaroid structure can laminate display panel's display area and outer pin laminating district simultaneously, for prior art, saved the metal in outer pin laminating district and walked the glued process flow of line top coating protection, can avoid coating the protecting glue on the polaroid, and make follow-up laminating technology can't go on.

The polarizing layer can be prepared by dyeing and stretching a polyvinyl alcohol film, and the polarizing layer prepared from the polyvinyl alcohol film is easy to absorb water and fade to lose polarizing performance, so that a layer of cellulose triacetate film with good optical uniformity and transparency is required to be used for isolating moisture and air on the upper surface and the lower surface of the polarizing layer, and the polarizing layer is protected from water and oxygen.
Specifically, after the polarizer body is obtained, a protective adhesive is coated on one side end of the polarizer body to form a colloid. Optionally, the protective glue may be epoxy resin or methyl methacrylate, and the thickness of the glue is equal to that of the polarizer body.
Specifically, after the colloid is connected to one side end of the polaroid body, the lower surface of the polaroid body and the lower surface of the colloid are attached to the release film, the upper surface and the lower surface of the polaroid structure can be distinguished from the release film, the lower surface of the polaroid structure is attached to the release film, the polaroid body and the colloid can be protected, the release film has the characteristic of being easily stripped, when the polaroid structure is attached to the display panel, only the release film needs to be torn down, and the polaroid body and the colloid cannot be damaged. And protective films are attached to the upper surface of the polarizer body and the upper surface of the colloid, so that the protective films are high in strength and can effectively protect the integrity of the polarizer structure. Illustratively, pressure-sensitive adhesive is coated on the release film and the protective film respectively, and the release film and the protective film are attached to the polarizer body after drying treatment, so that the polarizer structure is formed. After the upper and lower surface of polaroid body and colloid had attached the protection film respectively and had left the type membrane, carry out drying process and curl the storage to the polaroid structure, when preparing display panel, can obtain the polaroid structure of demand size through cutting out the polaroid structure. The release film and the protective film are torn off, and the lower surface of the colloid has strong adhesion and can be firmly attached above the metal wiring; the adhesive property of the upper surface of the colloid is low, and the colloid can not be adhered to other substances after the protective film is torn off so as to influence the display effect of the display surface.
The preparation method of the polarizer structure provided by this embodiment is to integrate the polarizer and the colloid, connect the colloid to one side end of the polarizer body, attach a release film to the lower surface of the polarizer body and the lower surface of the colloid, and attach a protection film to the upper surface of the polarizer body and the upper surface of the colloid to form the polarizer structure. Therefore, when the protective adhesive for covering the metal wiring is formed in the outer pin attaching area of the display substrate, the protective adhesive for the metal wiring can be formed by attaching the polarizer body and the colloid to the display substrate in an aligned manner by only adopting the polarizer structure provided by the embodiment of the invention, so that the colloid covers the metal wiring in the outer pin attaching area, the protective adhesive for the metal wiring is formed, the coating and curing processes of the protective adhesive are simplified, the thickness of the colloid is not greater than that of the polarizer body, namely, the colloid is not too large, and the colloid is not coated on the upper surface of the polarizer body. Therefore, when the polaroid structure is used for preparing a display panel, the process difficulty of forming protective glue in the outer pin attaching area can be reduced, the thickness of the protective glue (colloid) can be ensured, the adhesion reliability of the colloid is improved, the protective glue can be prevented from being coated on the upper surface of the polaroid body, and the subsequent attaching process of the polaroid is ensured; meanwhile, the colloid and the polaroid can be attached at the same time, and the process difficulty of preparing the display panel can be reduced.

Fig. 3 is a flowchart of another polarizer structure manufacturing method according to an embodiment of the present invention, and referring to fig. 3, the polarizer structure manufacturing method includes:
Specifically, in order to enable the colloid to be firmly adhered to the outer pin attaching area, the colloid is prevented from falling off from the upper side of the metal wiring when the outer pin attaching area is bent, and therefore the adhesiveness of the lower surface of the colloid is larger than that of the upper surface of the colloid. The lower adhesiveness of the upper surface of the colloid than that of the lower surface can be realized by processing the surface of the colloid and designing the molecular structure of the colloid material. For example, a surface modifier for reducing adhesion may be doped on the upper surface of the colloid, and the surface modifier may be nanoparticles, and the adhesion of the upper surface of the colloid may be changed by mixing the nanoparticles on the upper surface of the colloid.
And 340, attaching protective films to the upper surface of the polarizer body and the upper surface of the colloid, and attaching release films to the lower surface of the polarizer body and the lower surface of the colloid.
