[0020] Figure 2 It is a structural schematic diagram of another implementation manner of the film tearing structure of the backlight module in one embodiment of the utility model. DETAILED DESCRIPTION

[0021] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0022] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. 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.

[0023] 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.

[0024] In the related art, since the protective film has a large area and the tear handle is located on one side, when tearing it off, the protective film away from the tear handle requires greater force to tear off, which can easily tear the original film material on the backlight module and affect the normal backlight function.

[0025] In view of the above problems, an embodiment of the present application provides a film tearing structure of a backlight module, which can easily tear off the protective film on the backlight module, thereby preventing the original film material of the backlight module from being torn off and ensuring normal backlight function.

[0026] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0027] See also Figure 1 and Figure 2 A film tearing structure of a backlight module includes: a protective component 100 and a release film 200, the protective component 100 includes a first film layer 110 and a second film layer 120, the first film layer 110 is arranged on the second film layer 120, a glue coating portion 111 is opened on the first film layer 110, and a gap-avoiding portion is opened on the second film layer 120, and the glue coating portion 111 is flush with the gap-avoiding portion; the second film layer 120 is arranged on the release film 200, and the glue coating portion 111 adheres to the release film 200.

[0028] It should be noted that the release film 200 has a rectangular cross-sectional structure, the first film layer 110 has a rectangular cross-sectional structure, and the second film layer 120 has a rectangular cross-sectional structure. The first film layer 110 is a PET protective film, the second film layer 120 is a PE soft film or a PET hard film, the adhesive portion 111 is the adhesive portion of the first film layer 110, and the air-avoiding portion is the hollowed-out portion of the second film layer 120 corresponding to the adhesive portion 111, so that the adhesive portion 111 adheres to the backlight module. That is, in addition to the adhesive exposed on the adhesive portion 111 on the first film layer 110, the remaining adhesive portions of the first film layer 110 are bonded to the second film layer 120, thereby reducing the area of ​​the adhesive portion in contact with the backlight module, so that when tearing it off, it does not require much effort to tear it off, thereby avoiding the original film material of the backlight module from being torn off, and ensuring the normal backlight function.

[0029] It should also be noted that the length of the glue coating portion 111 is between 20 mm and 80 mm, and the width is between 2 mm and 10 mm, which can be specifically determined according to the size of the backlight module.

[0030] See also Figure 2 In one embodiment, the protective component 100 further includes a tear handle 130 , and the tear handle 130 is disposed on the first film layer 110 .

[0031] It should be noted that the tear handle 130 is provided to facilitate tearing off the first film layer 110 .

[0032] In one embodiment, the protective component 100 further includes an adhesive portion, which is disposed on the second film layer and adheres to the first film layer 110. Specifically, the protective component 100 further includes a non-adhesive portion, which is disposed on the second film layer 120 near the release film 200.

[0033] It should be noted that the second film layer 120 has adhesive on one side or both sides. The adhesive portion is the adhesive portion of the second film layer 120 , and the non-adhesive portion is the non-adhesive portion of the second film layer 120 , and the non-adhesive portion faces the backlight module.

[0034] See also Figure 1 In one embodiment, the surface area of ​​the second film layer 120 is smaller than the surface area of ​​the first film layer 110 .

[0035] It should be noted that the second film layer 120 mainly functions to reduce the area of ​​the sticky portion of the first film layer 110 .

[0036] See also Figure 1 In one embodiment, the surface area of ​​the release film 200 is greater than the surface area of ​​the first film layer 110 . Specifically, the surface area of ​​the release film 200 is greater than the surface area of ​​the second film layer 120 .

[0037] It should be noted that the release film 200 is used to protect the first film layer 110 and the second film layer 120 , so the surface area of ​​the release film 200 is slightly larger.

[0038] The scheme of the present application has been described in detail above with reference to the accompanying drawings. In the above embodiments, the descriptions of the various embodiments have their own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
