The design of the fixed structure of the optical film is proposed due to the problem that the structure causes the source of the light source to be limited. [Previous technology] Among all kinds of flat-panel displays, liquid crystal displays have the advantages of thin body, light weight, and low power consumption. In addition, in recent years, as manufacturing technologies have matured, product yields have improved, and Factors such as increased production capacity and good manufacturing cost control by various manufacturers make the LCD monitor's general selling price acceptable to consumers, and it has become a mainstream display product in the consumer market. With the rapid development of thin-film transistor (TFT-LCD) liquid crystal displays, future research and development trends will focus on high-brightness, high-resolution and other directions. Therefore, in response to the market demand for large-size displays, the liquid crystal display The backlight module lamp used to actively provide the light source of the LCD panel in China needs to be changed or added in accordance with the corresponding changes. It also makes the light guide plate on the side of the lamp and the optical film fixing method of the light guide plate must also respond to the lamp Change or increase, and it is one of the important considerations in the research and development of liquid crystal displays. Currently, there are two types of fixed structure design of optical films in liquid crystal displays: one is as shown in the fifth figure. , Which is to make the two corresponding side walls of the LCD monitor base (50 0) are scheduled respectively | the inner side of the moon to extend the partition to open ^ M256500 into the positioning groove (5 1), the positioning groove (5 丄) and has a longitudinal extension A positioning post (5 2), a convex piece (61) corresponding to the width of the positioning groove (51) is extended on two corresponding sides of the optical film (60), and the convex piece (61) has a corresponding positioning post 52) positioning holes (62), whereby the optical film (60) is mounted on the base (50), covers the pre-assembled light guide plate, and utilizes laterally extending tabs (6 steps) Protrude into the positioning groove (5 1), and match the positioning hole (6 2) with the positioning post (5 2) to fix the optical film (60) in the base (50) of the liquid crystal display. Secondly, as shown in the sixth figure, it is also similar that the two corresponding side walls of the liquid crystal display base (70) are respectively extended inwardly toward the inner side to form a positioning groove (71), and the optical film (80) ) A convex piece corresponding to the width of the positioning groove (7 1) is extended at two corresponding sides. Unlike the former, the positioning groove of the base is not provided with a post, and the convex piece (8) of the optical film (80) 1) No positioning hole is set on the top, and a baffle (72) is set on the upper slot of the positioning groove (71), so that the optical film (80) is installed on the base (70) and covered by the light guide plate , Using its convex piece (81) to protrude into the positioning groove (71), the baffle (72) is limited above the convex piece (81), so that the optical film (70) is fixed to the base (80) of the liquid crystal display )Inside. However, the aforementioned optical film utilizes the combined structure of the laterally extending projections on both sides and the positioning grooves preliminarily fixed on the display base, so that the optical film can be fixed in the base. However, due to the positioning groove design of the two corresponding side walls of the base , Can only allow the lamp to be located at the other two corresponding side walls in the base, to project light to the two ends of the light guide plate under the optical film, but as the size of the LCD panel increases, in order to maintain the M256500 LCD display For the requirements of high brightness and high resolution, the number of light tubes in the back module must be relatively increased, that is, the light tubes must be distributed around the light guide plate to provide sufficient light sources. In this way, the optical film used in the front exposure The design of the combined structure between the film and the base of the display can no longer be used, and it can not achieve the function of multi-entry light. Therefore, the combined structure between the optical film and the base must be reconsidered and resolved. [New content] The main purpose of this creation is to provide an optical film fixing structure for a liquid crystal display, which is used to solve the problem that the source of the light source is limited due to the combined fixing structure between the optical film and the base in the aforementioned liquid crystal display. In order to achieve the purpose of the previous disclosure, the technical solution proposed by this creation is to make the optical film fixing structure of the liquid crystal display mainly to define the lamp tube installation interval on the inner periphery of the liquid crystal display base, and provide a lamp tube that can be placed on the outer side of the lamp tube. The reflectors are set in groups, and the diaphragm positioning section corresponding to the shape of the diaphragm is defined in the base relative to the inside of the lamp tube installation section. An optical diaphragm set is provided, and the top edge of the lamp reflector is positioned adjacent to the diaphragm. Positioning projections extending upward at the intervals are fixed against the periphery of the optical film. The design of the technical solution previously unveiled in this creation will achieve the following effects: This creation uses the lamp tube reflector to fix the structural design of the optical diaphragm, so that there is enough space in the base to provide the lamp tube assembly relative to the periphery of the light guide plate. Among them, the surrounding lamps can allow multiple sides of the light guide plate to enter the light, so that the source of the backlight module of the liquid crystal display is not limited, which is conducive to the design of large-size liquid crystal displays and provides sufficient light sources. On the other hand, the optical film is made of a simple square shape, and there is no need for a convex sheet extending outward, so as to save the high cost of M256500 optical film material and reduce costs. [Embodiment] The specific implementation of the optical film fixing structure of the liquid crystal display of this creative creation ▲ People, — as shown in the figure, it is mainly based on a predetermined group set on the inner periphery of the square base (1 0) of the liquid crystal display to define the lamp tube installation The section 'provides the lamp tube (20) and the outer lamp reflectors 丄) of which are respectively set in their towels, and the base (1 (n with respect to the inside of the lamp tube installation section (13) defines the corresponding film (3 〇) Shaped film positioning section (12), providing optical film (30) set in which 'make the top edge of the lamp sound reflector (2 1) adjacent to the film positioning section (12) to form an upwardly extending A positioning projection (22), which can be disposed at the corner 隅 4 (as shown in the second figure) or the side of the lamp reflector (2 1) adjacent to the film positioning section (1 2). The edge (as shown in the third picture). The design of the previous technical solution of this creation, when applied to the liquid crystal display group, can be placed in the base (i 〇) with a light guide plate (4 〇), with: The light guide (40) is provided with a lamp tube (20) and a lamp reflector (21) located outside the lamp tube (20). ), And then set the optical film (30) on the light guide plate (40) relative to the lamp reflector (2 workers) to surround the film positioning area (12), and use each lamp reflector (21) The positioning convex piece (22) extending upward is abutted against the periphery of the optical film (30), the optical film (30) is fixed, and then a liquid crystal panel is installed on the optical film (30) And the upper frame and other components (not shown), that is, a liquid crystal display. M256500 As can be understood from the foregoing description, this creation uses a lamp reflector to fix the structural design of the optical film, so that the base can be opposed to the light guide plate. The lamps are arranged around each side, so that the lamps around the light guide plate can project light from each side of the light guide plate, so that the source of the backlight module of the liquid crystal display is not restricted, which is conducive to the design of large-size liquid crystal displays and provides Sufficient light source. On the other hand, 'make the optical film a simple square shape, without the need to extend outwards to save high-priced optical film material and reduce costs. Therefore, this creation with its innovative technical solution, Can indeed overcome the conventional optical film The shortcomings caused by the fixed structure caused by the source of the light source have significant progress. Therefore, this creation conforms to the new patent requirements, and the application is submitted according to the law.
