[Prior Art] The diffusion film and diffusion plate on the market, for example, the diffusion film for backlight modules commonly used in the market, the function of which is to provide a uniform surface light source for the liquid crystal display, and the conventional diffusion film is mainly added to the diffusion film substrate. Chemical particles are used as scattering particles, and the microparticles of the existing diffusion plate are dispersed between the resin layers; when the light passes through the diffusion film or the diffusion plate, it will continuously pass through the medium with different refractive index, and refraction, reflection and refraction occur. The phenomenon of scattering, thus achieving the effect of optical diffusion. Reference may be made to Japanese Patent No. 200807033 and JP71749〇9, which are directed to a diffusion sheet which is coated with a light-transmissive resin containing resin particles on a matrix film or a light-transmissive resin film having an internal diffusion function. ©成; and as in the national invention No. 290232 invention patent, which indicates a scratch-resistant diffusion film, because the scratch-resistant diffusion film has a hard coating to prevent warpage, and to avoid scratching when the diffusion film is used in the backlight module In the case of a concentrating film, 'JP08-146207' 'optical diffusion film' discloses a surface-structured optical diffusion film. However, the aforementioned conventional diffusion film and diffusion plate have the following defects: 1. Since the top surface of the existing substrate is not commensurate with the structure of the bottom surface, it is easy to produce warpage in 200944839, which results in a low yield ratio, regardless of whether the surface of the diffusion film is covered with a resin containing a resin particle, which is disproportionate. It is easy to produce warpage. 2. It is easy to cause scratching: Whether it is a light-transmissive resin containing resin particles on the surface of the diffusing film, it is easy to place it correspondingly.刮 Scratch the brightness enhancement film in the backlight module. 3. Costly: The structure of the top and bottom surfaces of the substrate is structured by 4» or by matrix coating, or attached to the substrate film. Applying the surface structure of the diffusion film or other film of the resin particles to scratch, in this case, in order to avoid warping or injury, a common method is to form a hard coating on the substrate, which can avoid warpage. Or, in the case of injury, it also increases the burden of manufacturing costs. [Invention] In view of the fact that the above-mentioned diffusion film and diffusion plate are modified and improved in the actual implementation of the use of the diffusion film, And the concept, and with the aid of professional knowledge and experience, as well as the ingenuity and experimentation, the present invention is a light modulation structure, which comprises a substrate, and a plurality of non-circles are arranged inside the substrate. a modulation unit of spherical particles, and a refractive index inside each of the modulation units is smaller than a refractive index of the substrate. Each modulation unit is internally made of air or a vacuum. The modulation units are arranged vertically inside the substrate. , or in the same plane arranged inside the substrate (not arranged above and below). 5 200944839 The size of the modulation units can be the same or different. The arrangement of the modulation units can be matrix, radiation a shape, a spacer arrangement, a hexagonal arrangement, a random arrangement, or an arbitrary arrangement. ^ Further, the surface of the substrate may have a plurality of brightening units. The present invention is to arrange a number modulation unit inside the substrate, and The surface of the substrate is not structured, or the light-transmitting tree containing the resin particles is coated on the substrate, that is, the top surface of the substrate is commensurate with the structure of the bottom surface, and the distortion is not easily caused; and the surface of the substrate is not Structure or resin particles, so it is not easy to damage other film layers corresponding thereto.

Various light sources such as an organic light emitting diode (0LED) and a intensity discharge gas lamp (h^d), and the first to sixth preferred embodiments may be used singly or in combination with each other. However, the foregoing implementation The examples or drawings are not intended to limit the scope of the invention, and the scope of the invention is to be construed as being limited to the scope of the invention. According to the above description, it can be seen that the light modulation structure of the present invention has at least the following advantages: 1_Because the structure of the top surface and the bottom surface of the substrate is commensurate with each other, warpage is not easily generated, thereby improving the yield: The invention relates to the arrangement of a plurality of modulation units in the substrate, instead of structuring the surface of the substrate or coating the substrate with a light-transmissive resin containing resin particles, that is, the top surface of the substrate is commensurate with the structure of the bottom surface, and is not easy to be warped. Qu, and then improve the yield. 2. The case where the wound is not easily generated: The present invention is to arrange a number of modulation units in the inside of the substrate. The surface of the substrate does not have a structure or resin particles, and thus it is difficult to scratch other film layers corresponding thereto. ,
