These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0024] Unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] In the related art, a piece of adhesive paper is usually pasted on the protective film, but due to the deviation between the polarizer and the LCD screen, part of the adhesive paper is pasted on the LCD screen. As time goes by, the adhesive paper on the polarizer part will not be sticky enough, making it impossible to tear off the protective film.

[0026] In view of the above problems, an embodiment of the present application provides a polarizer film tearing structure for an LCD screen, which can easily tear off the protective film on the polarizer.

[0027] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0028] See also Figure 1 , Figure 2 and Figure 3 A polarizer tearing structure for an LCD screen includes: a light guide 100 and an adhesive member 200, the light guide 100 includes a protective film 110, the protective film 110 has a first right-angle portion 111; the adhesive member 200 includes an adhesive portion 210 and a tearing portion 220, the adhesive portion 210 is connected to the tearing portion 220, the adhesive portion 210 adheres to the protective film 110, the adhesive portion 210 has a second right-angle portion 211, and the first right-angle portion 111 and the second right-angle portion 211 are flush with each other.

[0029] It should be noted that the adhesive member 200 is an adhesive paper with a rectangular cross-sectional structure. The adhesive area is large. The size of the protective film 110 is the same as that of the polarizer 120, so as to protect the polarizer 120 from being scratched in all directions. Furthermore, the tearing portion 220 is a tearing handle for easy tearing. The first right angle portion 111 is a right angle on the protective film 110. Two are provided in the present application, one on the upper and lower polarizers 120, respectively. Correspondingly, two second right angle portions 211 are also provided, one on the upper and lower polarizers 120, respectively. Further, by bonding the second right angle portion 211 of the adhesive portion 210 to the first right angle portion 111 of the protective film 110, since the polarizer 120 needs to be cut, the right angle side of the polarizer 120, that is, the first right angle portion 111 on the protective film 110, is continuously squeezed during the cutting process, so that the right angle of the first right angle portion 111 has poor adhesion, which is conducive to tearing off the entire protective film 110.

[0030] See also Figure 2 Specifically, the first right-angle portion 111 includes a first side 111a and a second side 111b, and the first side 111a is perpendicular to the second side 111b.

[0031] See also Figure 3 Specifically, the second right-angle portion 211 includes a first glue edge 211a and a second glue edge 211b. The first glue edge 211a and the second glue edge 211b are perpendicular to each other, the first glue edge 211a and the first side edge 111a are flush with each other, and the second glue edge 211b and the second side edge 111b are flush with each other.

[0032] It should be noted that the first side 111a and the second side 111b form a right angle at their intersection, and the first adhesive edge 211a and the second adhesive edge 211b form a right angle at their intersection. The two right angles overlap each other, and the right angle has poor adhesion, so tearing starts from the right angle.

[0033] See also Figure 1 In one embodiment, the light guide member 100 further includes a polarizer 120 , and the protective film 110 is disposed on the polarizer 120 .

[0034] See also Figure 1 In one embodiment, the light guide member 100 further includes a glass substrate 130 , and the polarizer 120 is disposed on the glass substrate 130 .
