Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, in particular to a polarizing film structure that is easy to identify. Background Art

[0002] In LCD screens, polarizers are required, that is, polarizers are attached to the LCD glass. After the polarizers are attached to the glass, the protective film on the surface of the polarizers needs to be torn off before full bonding. Figure 1 As shown, in order to prevent the protective film from falling off, the adhesion between the protective film and the polarizer body is usually relatively large, and the polarizer is a special-shaped structure, so the protective film is difficult to tear off. Therefore, it is usually necessary to add a sticky paper a on the protective film, and use the sticky paper as a tear handle to tear off the protective film, but adding sticky paper will increase the processing cost. In addition, the polarizers that usually need to be attached to the LCD screen are divided into upper polarizers and lower polarizers. During the attachment process, it is easy to confuse the upper polarizer and the lower polarizer, resulting in reverse attachment.

[0003] In view of the above, a polarizer structure that is easy to identify is proposed, so that not only the protective film can be easily torn without providing adhesive paper to reduce processing costs, but also the polarizer can be easily identified and distinguished. Utility Model Content

[0021] Figure 3 A schematic diagram of a stacked structure of a polarizer structure for easy identification in an embodiment of the utility model;

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] See also Figure 2 and Figure 3 As shown, a polarizer structure that is easy to identify includes: a protective film 100, a polarizer body 200 and a release film 300, wherein the protective film 100, the polarizer body 200 and the release film 300 are stacked in sequence; and the side of the polarizer body 200 facing the release film 300 is a sticky surface, and the side of the polarizer body 200 facing the protective film 100 is a non-sticky surface, the protective film 100 is used to isolate and protect the non-sticky surface, and the release film 300 is used to isolate and protect the sticky surface; the protective film 100 has four corner ends, one of which is raised relative to the polarizer body 200 to form a film tearing protrusion 110, and an identification mark 400 is provided on the film tearing protrusion 110.

[0025] It should be noted that, in this way, the protective film 100 can be easily torn off by the tearing protrusion 110, which can reduce the production cost compared with the existing polarizer structure by attaching adhesive film paper; further, the identification mark 400 is set on the tearing protrusion 110, and the identification mark 400 is convenient for identifying and distinguishing the upper polarizer and the lower polarizer. Figure 4 As shown, it should also be noted that the shape of the polarizer used in the mobile phone is usually a special-shaped structure, so a corresponding cutting tool is required to punch the square-structured polarizer into a special shape. When the mold punches the shape of the polarizer, the depth of the cutting tool b at any of the four corner ends is controlled so that the corner end only cuts the release film 300 and the polarizer body 200, leaving the protective film 100 uncut, thereby forming a tearing protrusion 110, that is, the edge of the tearing protrusion 110 is a right-angle structure. Since the tearing protrusion 110 is the material of the protective film 100 itself, it can reduce the production cost compared to the existing polarizer structure by attaching adhesive film paper.

[0026] Preferably, the identification mark 400 is a white ink identification mark 400. That is, a white ink identification mark 400 is printed on the film tearing protrusion 110 to facilitate quick identification and distinction.

[0027] Preferably, the identification mark 400 is a knife mark 400. That is, a knife mark is added to the tear film protrusion 110, and the knife mark is used as the identification mark 400, for example, "↑" represents the upper film, "↓" represents the lower film, and other letters or numbers can also be used for easy identification.

[0028] Preferably, the protective film 100 is a PET (polyester) protective film 100. The PET film has the advantages of good wear resistance, not easy to be damaged, and good corrosion resistance, so it can ensure the protection of the polarizer body 200.

[0029] Preferably, the release film 300 is a PET release film 300. The PET film has the advantages of good wear resistance, not easy to be damaged, and good corrosion resistance, so it can ensure the protection of the polarizer body 200.

[0030] Preferably, the four peripheries of the polarizer body 200 and the four peripheries of the release film 300 are aligned with each other.

[0031] See also Figure 3 As shown, in one embodiment, the polarizer body 200 includes a first TAC (triacetyl cellulose film) layer, a PVA (polyvinyl alcohol) layer, a second TAC layer 240 and a PSA (pressure-sensitive adhesive) layer stacked in sequence, the protective film 100 is disposed on the side of the first TAC layer 220 away from the PVA layer 230, and the release film 300 is disposed on the side of the PSA layer 260 away from the second TAC layer 240. The PVA layer 230 is a layer for achieving polarization, the first TAC and the second TAC are used to isolate and protect the PVA body, for example, to prevent external water vapor and foreign matter from contaminating the PVA layer 230, and the PSA layer 260 is a pressure-sensitive adhesive, which plays a bonding role.

[0032] Furthermore, a first antistatic layer 210 is coated on one side of the first TAC layer 220 away from the PVA layer 230. Thus, the polarizer has antistatic properties. For example, the first antistatic layer 210 can be a coating containing antistatic particles.

[0033] Furthermore, a second antistatic layer 250 is disposed on one side of the second TAC layer 240 away from the PVA layer 230. That is, both sides of the polarizer have antistatic properties. The second antistatic layer 250 may be a coating containing antistatic particles.

[0034] Furthermore, a high temperature resistant layer may be disposed on the upper and lower surfaces of the PVA layer 230 , respectively, so that the polarizer has a high temperature resistant function, for example, the high temperature resistant layer is a polyimide film.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
