Description:
FIELD 
       [0001]    The present disclosure relates to the technical field of liquid crystal display modules and, in particular, to a reinforcement structure for an optical film and an optical film for application therewith. 
       BACKGROUND 
       [0002]    In the prior art, an optical film is usually provided thereon with a positioning hole and a positioning pillar, which hole and pillar cooperate together to function for positioning the optical film. As liquid crystal displays and television sets grow constantly in size, the size of an optical film applied in a liquid crystal backlight module increases as well. Since the dimensions of the positioning hole and the positioning pillar are restricted by the borders of the liquid crystal display module, they cannot increase in a corresponding manner. While the size of the optical film increases, and the dimensions of the positioning hole and the positioning pillar remain unchanged, the positioning hole is fragile to deformation or damage due to the increased force exerted on the positioning hole. 
       SUMMARY 
       [0003]    It is an embodiment of the present disclosure to provide a reinforcement structure for an optical film and an optical film for application therewith, so as to solve the problem that the positioning hole in a prior art optical film is easily deformable or damageable. 
         [0004]    In order to achieve the above object, in a first aspect of the present disclosure, a reinforcement structure for an optical film is provided, which reinforcement structure may be arranged around a positioning hole in the optical film and/or on a positioning pillar in the optical film, for enhancing the structural strength of the positioning hole and/or the positioning pillar. 
         [0005]    In one embodiment of the present disclosure, the reinforcement structure may comprise at least one of a reinforcement rib and a reinforcement ring. 
         [0006]    Therein, the reinforcement structure may be made from an organic thin film or made from the same material as the optical film. 
         [0007]    In another embodiment of the present disclosure, the reinforcement structure and the optical film may be adhesively connected or connected by hot pressing. 
         [0008]    Therein, when the reinforcement structure is arranged around the positioning hole, the reinforcement structure may be shaped the same as the positioning hole. 
         [0009]    In a further embodiment of the present disclosure, the reinforcement structure may be adhesively connected via an adhesive tape with the optical film. 
         [0010]    Therein, a surface of the reinforcement structure may be provided with a glue layer, the glue layer being adhesively connected around the positioning hole and/or on the positioning pillar. 
         [0011]    In a yet further embodiment of the present disclosure, the reinforcement structure may be arranged on at least one of a frontal and a back of the optical film. 
         [0012]    In a second aspect of the present disclosure, an optical film is provided, with the above-said reinforcement structure being provided around a positioning hole in the optical film and/or on a positioning pillar. 
         [0013]    Therein, the frontal and the back of the optical film are both provided with the reinforcement structure. 
         [0014]    The reinforcement structure for an optical film and the optical film for application therewith, as provided by the embodiments of the present disclosure, can be arranged around a positioning hole in the optical film and/or on a positioning pillar in the optical film, for enhancing the structural strength of the positioning hole and/or the positioning pillar. For example, the reinforcement structure may be arranged on a frontal or a back of the optical film, or alternatively, both the frontal and the back may be arranged with the reinforcement structure. The reinforcement structure around the positioning hole can enhance the structural strength of the positioning hole, while the reinforcement structure on the positioning pillar can enhance the structural strength of the positioning pillar; when the positioning hole and the positioning pillar are mated, the reinforcement structure is able to effectively avoid deformation or damage due to insufficient strength in positioning.

     DETAILED DESCRIPTION 
       [0019]    The embodiments of the present disclosure will be described in detail as follows in conjunction with the accompanying drawings. 
         [0020]    In the description of the present disclosure, it is to be understood that the terms “frontal”, “back”, etc. indicate locations or positional relationships that are shown based on what are shown in the drawings, which are aimed only at facilitating the description the present disclosure and simplifying the description, rather than indicating or implying that relevant means or elements must be provided with particular locations, or constructed and operated at the particular locations, and accordingly cannot be understood as limitations to the present disclosure. 
         [0021]    In the description of the present disclosure, it is to be understood that unless prescribed and defined otherwise, the terms “mounted”, “linked” and “connected” should be understood in a broad sense, e.g. it can be a fixed or detachable connection, or alternatively an integral connection; it can be direct connection or connection via an intermediate medium, or internal communication of two elements. For an ordinarily skilled in the art, the above terms can be understood specifically according to specified circumstances in the present disclosure. 
         [0022]    Referring to  FIG. 1 ,  FIG. 2  and  FIG. 3 , in an embodiment of the present disclosure a reinforcement structure  102  for an optical film is provided, which is arranged around a positioning hole  103  in the optical film  101 , for enhancing the structural strength of the positioning hole  103 . For example, the reinforcement structure  102  can be arranged on a frontal or a back of the optical film  101 , or arranged on both the frontal and the back thereof. The reinforcement structure  102  around the positioning hole  103  can enhance the structural strength of the positioning hole  103 . When the positioning hole  103  is mated with a positioning pillar (not shown), the reinforcement structure  102  is able to effectively avoid deformation or damage due to insufficient strength in positioning. 
         [0023]    The reinforcement structure  102  may comprise a reinforcement rib and a reinforcement ring. The reinforcement rib or reinforcement ring can better enhance the structural strength of the positioning hole  103 . Moreover, the reinforcement rib and reinforcement ring can be easily available, of which the manufacturing processes are simple and low in cost. 
         [0024]    The reinforcement structure  102  may be made from an organic thin film or made from the same material as the optical film  101 . The organic thin film or the similar material to that of the optical film  101  is selected for manufacturing the reinforcement structure  102  so that a better match can be reached between the reinforcement structure  102  and the optical film  101 , and accordingly, the effect of connection between the reinforcement structure  102  and the optical film  101  is improved thus enhancing the structural strength of the positioning hole  103 . 
         [0025]    The reinforcement structure  102  may be adhesively connected or connected by hot pressing with the optical film  101 . For example, a surface of the reinforcement structure  102  may be provided with an adhesive layer, which layer is adhesively connected with the optical film  101  so as to effect a connection between the reinforcement structure  102  and the optical film  101 ; or, the reinforcement structure  102  and the optical film  101  are adhesively connected by an adhesive tape so as to effect a connection between the reinforcement structure  102  and the optical film  101 . When the reinforcement structure  102  is made from the same material as the optical film  101 , the reinforcement structure  102  and the optical film  101  can be connected by a hot pressing process, in which connection the reinforcement structure  102  and the optical film  101  are provided with a more stable connection thus enabling a better match between the reinforcement structure  102  and the optical film  101 . 
         [0026]    In addition, the reinforcement structure  102  may be shaped the same as the positioning hole  103  so that a better match can be reached between the reinforcement structure  102  and the positioning hole  103 , and the appearance is more pleasant. 
         [0027]    Therein, the reinforcement rib or reinforcement ring may be adhesively connected around the positioning hole  103  by an adhesive tape. Alternatively, a surface of the reinforcement rib or the reinforcement ring can be provided with a glue layer, and the glue layer is adhesively connected around the positioning hole  103  so as to effect a connection between the reinforcement structure  102  and the optical film  101 . 
         [0028]    In particular, the reinforcement structure  102  may be arranged on a frontal and a back of the optical film  101 . Since both the frontal and the back of the optical film  101  are provided with the reinforcement structure  102  to enable a greater structural strength around the positioning hole  103 , a deformation of or a damage to the positioning hole  103  can be effectively avoided. 
         [0029]    Referring to  FIG. 4 , the reinforcement structure  102  may also be arranged on a positioning pillar  104  in the optical film  101  so that the structural strength of the positioning pillar  104  can be enhanced. In this way, the reinforcement structure  102  may be arranged on the positioning hole  103  and the positioning pillar  104  at the same time, such that the structural strengths of the positioning hole  103  and the positioning pillar  104  can be both enhanced thus improving further the capability of enduring a greater stress when the positioning hole  103  and the positioning pillar  104  are mated. 
         [0030]    In an embodiment of the present application an optical film  101  is also provided, in which the above-said reinforcement structure  102  is arranged around a positioning hole. The reinforcement structure  102  is arranged around the positioning hole  103  in the optical film  101  for enhancing the structural strength of the positioning hole  103 . For example, the reinforcement structure  102  may be arranged on a frontal or a back of the optical film  101 , or arranged on both the frontal and the back thereof. The reinforcement structure  102  around the positioning hole  103  can enhance the structural strength of the positioning hole  103 . When the positioning hole  103  is mated with a positioning pillar, the reinforcement structure  102  is able to effectively avoid deformation or damage due to insufficient strength of the positioning hole  103 . 
         [0031]    In particular, both the frontal and the back of the optical film  101  are provided with the reinforcement structure  102  so that the positioning hole  103  on the optical film  101  gains a better structural strength. 
         [0032]    In this description, the specific features, structures, materials or characteristics can be combined in an appropriate manner in any one or more embodiments or examples.

Any skilled person familiar with the art can easily and readily conceive of a variation or replacement within the disclosed technical scope of the present disclosure, and the variation or replacement should be included in the scope of the present disclosure.
