Description

201035622 VI. Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display, and particularly to a positioning device for an optical film of a liquid crystal display. [Prior Art] Recently, optoelectronic technology has been continuously introduced, and digitalization has promoted the vigorous development of the liquid crystal display market. Therefore, it is widely used in personal digital assistants (pD power phones, camcorders, notebook computers, desktop monitors 2, and projection TVs, etc., on consumer communication or electronic products, etc., On behalf of the cathode ray tube, it has become the mainstream of the display. The buckle, and gradually take the backlight module as one of the key components of the liquid crystal display, the crystal itself will not emit light, so most of the liquid crystal displays generally need a group of 'can display the naked eye. The perceived image. This makes the German U _ degree more uniform, the manufacturer often f will add optical film brightness and distribution in order to make the shirt photo, such as light guide, diffuser or brightening. In order to adjust the emitted light to accurately clamp the optical film, the optical film and the frame are combined, thereby restraining the optical film from being used for the degree of freedom of adhesion. However, since the preparation of the sheet in the direction of the vertical frame or the assembly manpower is required The invention is a burden on the side wall of the frame, which is an optical module. Blocking the degree of freedom of the optical film in the direction of the vertical frame. According to an embodiment of the invention, an optical module includes an optical film, a frame and a limiting block. The optical film includes a main body portion, a connecting portion and a lug. The connecting portion is connected to the lug and the main body portion. The frame comprises a bottom plate and a side wall. The bottom plate carries an optical film. The side wall surrounds the edge of the optical film, and the side wall has a notch to break the side wall of the frame. The limiting block is disposed on the frame. On the side wall, 0 and extending from the side wall to the notch of the covering portion, and the lug is embedded in the notch and is restrained between the bottom plate of the frame and the limiting block. [Embodiment] FIG. 1 is a view of the present invention. A front view of an optical module 100 of an embodiment. Fig. 2 is a perspective view of a portion of the first embodiment of Fig. 1. As shown, an optical module 100 includes an optical film 110, a frame 120, and a limiting block 130. The diaphragm 110 includes a main body portion 112, a connecting portion 114 and a lug 116, wherein the connecting portion 114 connects the lug 116 and the main body portion 112. The frame 120 includes a bottom plate 122 and a side wall 124. The bottom plate 122 carries the optical film 110. Wai The edge of the optical film 110 has a notch 125 that breaks the sidewall 124 of the frame 。 0. The limiting block 130 is disposed on the sidewall 124 of the frame 120 and extends from the sidewall 124 to the notch 125 of the covering portion. The limiting block 130 and the side wall 124 of the frame 120 are preferably integrally formed, but are not limited thereto, and the lug 116 is lost in the notch 125 and is restrained between the bottom plate 122 of the frame 120 and the limiting block 130. That is to say, the optical module 1 of the present embodiment utilizes the limiting block 130 on the side wall 124 of the frame 120 6 201035622 to restrain the degree of freedom of the optical film 110 in the direction Z. Thus, the assembler No additional adhesive tape is required for assembly, as long as the lug 116 is embedded in the notch 125. The above-mentioned "the limiting block 130 and the side wall 124 of the frame 120 are preferably integrally formed" should be interpreted as: "the limiting block 130 and the side wall 124 are preferably connected to each other without interruption, and the materials thereof are uniform." For example, the material of the limiting block 130 and the frame 120 (including the bottom plate 122 and the side wall 124) of the present embodiment may be plastic, for example, polycarbonate (PC), so that the manufacturer can form the injection molding. The frame 120 and the limit block 130 are produced in a manner without additional manufacturing procedures. It should be understood that the above processes and materials are merely illustrative and are not intended to limit the invention. Various other processes can also be applied to manufacture the frame 120 and the limit block 130. The present invention has a general knowledge, and the embodiment of the frame 120 and the limiting block 130 should be flexibly selected according to actual needs, as long as the limiting block 130 is disposed on the side wall 124 of the frame 120 and the limiting block 130 and the side wall 124 can be combined. In the present embodiment, the number of the limiting blocks 130 may be a pair, and the limiting blocks 130 may cover opposite sides of the notch 125, respectively. That is to say, an opening 135 will be formed between the above-mentioned limiting blocks 130. When assembled, the lug 116 can pass through the opening 135 into the gap 125 to complete the positioning. In the present embodiment, the optical film 110 is, for example, a diffusion sheet, a brightness enhancement sheet, a reflection brightness enhancing sheet, a prism sheet or a protective sheet. The material of the lug 116 can be an elastic material. The term "elastic material" as used herein shall be interpreted as: "a material that can be restored to its original state after the external force has disappeared." Thus, during assembly, the assembler can slightly bend the lug 116 so that the lug 116 passes through the opening 135. . When the 201035622 / lug 116 passes through the opening 135, the assembler can release the lug 116, and the elasticity of the lug 116 itself will cause the lug 116 (f) to reinstate the shape notch 125. In fact, the lug 116 of the optical film 11G, the connecting portion ι 4 and the portion 112 may be formed in a body. That is to say, the lug 116, the connecting portion (1) and the main body portion 112 can be mutually interrupted, and (4). More specifically, the material of the upper lug 116, the connecting portion 114 and the main body portion ι 2 may be plastic, for example: f | , ο M 】 ^ methyl propyl methacrylate (Polymethyl

MethaCrylate; PMMA), Polycarbonate (Pc), =: = ί or other suitable material' is produced by the manufacturer in the form of hot pressing or injection molding. * Field, it should be understood that the above processes and materials are merely illustrative and are not intended to limit the invention. Other various types of ear m, Chalaga can also be applied to manufacture the lug 6, the connection σ|Μ14 and the main body portion 112. The technical knowledge of the present invention is generally known to the person skilled in the art, and should be elastically connected.

In the embodiment of the portion 114 and the main body portion (1), as long as the lug 116 and the connecting S= are connected to the main body portion, the sling lug 116 can be bent by an external force, and the original force can be restored after the external force disappears. ', to avoid the assembly personnel in the f-folding lug 116 when the main body 112 of the strip 110 is attached, so that the wind can be swayed, the manufacturer can clarify, and the optical characteristics of the cymbal Π 0 are affected. A relief groove is provided in the connecting portion 114. The number of the avoidance slots 140 may be a pair of '''s, which is the phase of the connection portion 1H: the two slots (10), the assembly personnel are in the _ 耳耳川; the force: the external force will not be transmitted to The main part of the optical film is 2], and the optical characteristics of the optical film 11 () are affected. 8 201035622 As for the relative size relationship of the components in the optical module 100, it depends on the material of the optical film 110. For the present embodiment, the manufacturer can determine the relative dimensional relationship of the components in the optical module 100 according to the following equations.
