Description

M281249 8. Description of the new type: [Technical field to which the new type belongs] This creation is an improvement of the structure of a light box, mainly by adding a light diffuser on the surface around the light source and the light diffuser to control the light travel of the light. , And an application product capable of providing a display function by achieving a light diffusion effect Y by a light diffuser. [Previous technology] The liquid crystal display panel itself does not have light-emitting characteristics, and requires a light source module to provide its light source. The direct-type backlight module used in general LCD TVs has its light source converted from several line light sources (cold-cathode tubes CCFL) to surface light sources. Provided for use with liquid crystal display panels. In the conventional technology, the direct type backlight module is used to eliminate the bright and dark bands produced by the insect-smooth surface. There are three ways to improve it. The first is to extinction the printing on the corresponding diffuser plate above the lamp tube, which not only consumes time, but also Increase the cost β Second is to add an extra matting transparent plate above the light tube. There are multiple grooves on the transparent plate or continuous thickness and thin are connected. How big is the liquid crystal display panel? How big is this matting transparent plate, which not only consumes materials And it will add weight. The third is to add an additional light guide plate and a plurality of transflective films on top of the lamp tube. The disadvantage of this method is how large the liquid crystal display panel is, how large the light guide plate is, which consumes materials and increases weight. The first picture is a schematic diagram of a conventional direct-type backlight module. The direct-type backlight module is mainly composed of a light source 11, a frame 12, a reflective plate 13, and a diffuser plate c. The light emitting surface 15 directly above the light source 11 is brighter, and the light source 11 is brighter. The light exit surface 15 in the middle of the light source 11 M281249 is darker, which results in the bright and dark bands of the light exit surface 15 being obvious and the uniformity being poor. The second figure is a schematic diagram of a direct-type backlight module that is familiar with the first method described above. The direct-type backlight module 2 is mainly composed of a light source 21, a frame 22, a reflective plate 23, a diffuser plate 24.4, and a brush 25. The third figure is a schematic diagram of a direct-type backlight module according to the second method. The direct-type backlight module 3 is mainly composed of a light source 31, a frame 32, a reflection plate 33, a diffusion plate 34, and a transparent plate 35. The third picture is a schematic diagram of the third method of a direct-type backlight module. The direct-type backlight module 4 is mainly composed of a light source 41, a frame 42, a reflective plate 43, a diffuser plate 44, a light guide plate 45, and a transflective film 46. composition. [New content] The purpose of this creation is to provide a low-cost light box structure with good light diffusion function. Another purpose of this creation is to provide a light box structure with a double-sided appearance. This creation is a light source module for the improvement and application of the light box structure. It mainly adds a light diffuser to the surface of the light source. The light diffuser is used to control the amount of diffused light from the light source. The rain reaches the amount of light required by the light source module. The application product that can provide the display function is in which the light diffuser surrounds the surrounding surface of the light source luminous body, and the surface of the light diffuser can be appropriately rough green or M281249 fogging or other light diffuser structure. Compared with the previous direct-lit backlight module technology, this creation has the following advantages: The light diffuser has a smaller volume and good light diffusion function, which can save material costs and provide a double-sided light source module. . [Implementation] The structure of this creation is to add a light diffuser or a plurality of light diffusers on the surface of the light source. The light diffuser is usually made of polyacrylic resin or polycarbonate or polystyrene or polyester. Made of other materials, the light diffuser can be injection molding, transfer molding, compression molding or tool processing. To illustrate this creative implementation, please refer to the following examples: One of the creative examples (see Figure 5): the light from the light source enters the light diffuser 55, the light 56 passes through the light diffuser 55, and then passes through the diffuser plate 54 to emit light , And then achieve the component light effect. The second creative example (see Figure 6): the light source 61 ray 661 enters the light diffuser 651, the light 661 exits through the light diffuser 651, and then exits through the diffuser plate 641. Another light source 61 ray 662 enters the light diffuser 652 The light energy 2 is emitted through the light diffuser 652, and then emitted through the diffuser plate 642 to achieve a component light effect. By the example-the secret can control the purpose of recording and spreading the silk record, and can save unnecessary extra material, thereby reducing weight and material cost. And the second example can easily feed the field—a kind of double-sided light box structure M281249 In summary, this creation has indeed met the requirements of the new patent, and a patent application has been filed in accordance with the law. However, the above is only a preferred embodiment of this creation, and the scope of this creation is not limited to the above embodiments. For example, those who are familiar with the skills of this case make equivalent modifications or changes based on the spirit of this creation. It should be covered by the scope of patent application under α.
