[Previous technology] In the structure of the liquid crystal [LCD] panel, because the liquid crystal [LCD] itself does not emit light, it needs an external light source as a source of light for color and pattern display. The most used structure in the industry at present That is, a backlight module using a cold cathode lamp [CCFL] or a light emitting diode [LED] as a light source; but because the cold cathode lamp [CCFL] is a linear light source, the light emitting diode [LED] is The point light source uses the side light source method and the direct type respectively, and the light source line is expanded and distributed into a uniform surface light source through the combination of an optical sheet and a diaphragm. • Among them, as shown in the third figure, it is a side light source method. The backlight module (5) is mainly provided with an optical sheet consisting of a light guide plate (511), a diffusion sheet (512), and a light collecting sheet (513). The film group (51) is provided with a reflective sheet (52) on the back surface of the light guide plate (511), and a liquid crystal (LCD) panel (53) is provided on the front surface of the light collecting sheet (513) to make the light source (54 ) After being introduced from the side surface of the light guide plate (511), the light source (54) can be diffused through the front surface of the light guide plate (511) by means of refraction or reflection in conjunction with the reflection of the reflection plate (52), and the diffuser plate (512) ) Make the light distribution more uniform, and then the light collecting sheet (513) allows the light to be concentrated in the effective viewing direction of the liquid crystal [LCD] panel (53). M273010 In addition, as shown in the fourth figure, it is a direct type. The backlight module (6) is composed of a diffuser plate (611), a diffuser sheet (612), and a light collector sheet (613). (61) A light source (62) is provided on the back end surface of the diffuser plate (611), a reflection sheet (63) is provided on the rear end surface of the light source (62), and a liquid crystal is provided on the front end surface of the light collection sheet (613) [ LCD] panel (64), when the light source (62) is reflected and introduced from the back end surface of the substrate diffusion plate (611) with a reflection sheet (62), it is diffused or diffused in the diffusion plate (611) by diffusion particles, which can be refracted or reflected Method, the front end surface of the diffuser plate (611) diverges, and then the diffuser sheet (612) makes the light distribution more uniform, and then the light collector sheet (613) allows the light to be concentrated in the liquid crystal [[CD] panel (64). Effective viewing direction. However, although the above-mentioned method can achieve the expected effect of making the light source distributed into a uniform surface light source regardless of the side-light source method or the direct-type method, it has been found in actual implementation that the structure of the side-light method and the direct-type method both require The light guide plate or diffuser plate, diffuser sheet, light collecting sheet, etc. are stacked and assembled to make it not only inconvenient in the production process, it takes a long time, but it also causes it. Increase in production cost; In addition, • Due to the increase in the size of liquid crystal (LCD) panels, it is easy to cause various optical films or plates to be wrinkled, scratched, and warped during their production, storage, and assembling of backlight modules And so on, and then reduce its production yield.

Coating single layer or overlapping multiple layers of light-transmitting materials to form upper and lower optical layers, respectively. The combination of the optical composite board makes it easier and faster to produce and produce more money. Production cost, and also can improve its production yield 0 [Embodiment] First, please read the first and second figures, the optical composite board of this creation is applied to the backlight module, mainly based on the optical composite board (1 ) The front surface is provided with a liquid crystal [LCD] panel (2), the back surface is provided with a reflective sheet (3), and then a light source (4) is provided on the side surface of the optical composite plate (1) or between the reflective sheet (3); Wherein: The optical composite board (1) is provided with a base layer (11) produced by light-transmitting materials (such as acrylic, plastic, glass, etc.) by die casting or injection, and the base layer (11 ) Optical surfaces (111) are formed on the upper and lower surfaces (112), and using die-casting or solution coating to form a single layer or multiple layers of light-transmitting materials (such as acrylic, plastic ...) on the upper and lower surfaces of the base layer (11), respectively. The upper and lower optical layers (12), (13), and the optical surfaces (ill), (112) and the upper and lower optical layers (12), (13) can be processed to form smooth, single surfaces or both It is an irregular rough shape with continuous undulations, a single surface or a specific pattern (fine rhombuses, triangles, squares, arcs, protrusions or depressions or a combination of one-dimensional or two-dimensional sections), and it is on the base layer (U) Adding fluorescer, water-resistant, diffusing particles, tiny pores, etc. to the upper and lower optical layers (12), (13), and the base layer (11) and the upper and lower optical layers (12), (13) Surface treatment [such as: coated with waterproof layer, anti-scratch layer-etc.]. The fluorescent compound added to the base layer (11) and the upper and lower optical layers (12) and (13) of the optical composite plate (1) can absorb the ultraviolet light energy emitted by the light source (4) and convert it into visible light. Wavelength to increase the utilization rate of light and reduce the possible damage caused by ultraviolet light to the material of the base layer (11) and the upper and lower optical layers (12), (13). M273010 The water-resistant base added to the base layer (n) and the upper and lower optical layers (12) and (13) of the optical composite board (1) can reduce the base layer (1 丨) and the upper and lower optical layers (12), (13) The water absorption of the material, in order to reduce the light uniformity change caused by the volume unevenness change of the base layer (11) and the upper and lower optical layers (12), (13) after water absorption. The diffusing particles added to the base layer (11) and the upper and lower optical layers (12) and (13) of the optical composite plate (1) can increase the base layer (11) and upper and lower optics by using the small particles to diffuse light. The layers (12) and (13) have a diffusivity to light to achieve a better diffusion effect. The tiny pores added to the base layer (11) and the upper and lower optical layers (12), (13) of the optical composite plate (1) can achieve light diffusion through the refractive index difference between the medium in the pores and the surrounding materials. Effect, increase the material's diffusivity to light. The optical composite board (1) has a waterproof layer added to the base layer (11) and the upper and lower optical layers (12) and (13), which can reduce the base layer (u) and the upper and lower optical layers (12) and (13). Absorption of water and gas' avoids the non-uniform influence of light volume distribution caused by changes in material volume. The scratch-resistant layer added to the base layer (11) and the upper and lower optical layers (12) and (13) of the optical composite plate (1) can reduce the base layer (Π) and the upper and lower optical layers (丨 2), ( 13) Scars caused by friction and collision with other objects. In this way, after the light source (4) is introduced from the side face or the back face of the optical composite plate (1), it can be refracted or reflected by the base layer (11) by the optical surfaces (111), (112), and the top and bottom, respectively. The optical layers (12) and (13) diffuse and collect light to achieve the purpose of distributing the light source (4) into a uniform surface light source.
