The study of anti-reflective optical films is very widely used in the field of optics. Anti-reflection films on the surface of optical components can enhance the overall performance of optical instruments. In recent years, liquid crystal displays (LCDs) have been widely used in various modern electronic products, such as personal computers, notebook computers, digital cameras, mobile phones, PDAs, and liquid crystal televisions (LCD TVs). Since the external light is about 4 to 5% reflective when it illuminates the surface of the glass or plastic substrate on the surface of the display, the liquid crystal display is easily interfered by external light when it is used, which affects the visual effect of the screen. Especially for LCD TVs larger than 2 inches, the effect of external light reflection on the surface of the screen is more obvious. v. In order to solve the interference of external light, the anti-glare film is widely used due to obvious factors such as dare and low cost. On the LCD screen of the notebook computer and computer. 1 is a schematic view showing the structure of an anti-glare film according to a conventional technique. The anti-glare film is added by anti-glare particles to achieve an anti-glare effect, as shown in the figure: the anti-glare film structure comprises a substrate 1 An anti-glare film coating 2 disposed on the substrate 1 'the anti-glare film coating 2 comprises a resin 3 and a light-scattering particle 4', which is prepared by coating an anti-glare film coating solution On the substrate 1, the solvent contained in the anti-glare coating liquid is evaporated through a box, and then the resin 3 in the anti-glare coating liquid is hardened by ultraviolet light irradiation or a soft box. 099122070 Form No. A0101 Page 3 of 19 0992038860-0 201202752 The anti-glare film coating 2 should be formed. The light-scattering particles 4 in the anti-glare film coating layer 2 are uniformly dispersed in the anti-glare film coating liquid when the anti-glare film coating liquid is just coated on the substrate 1, when the anti-glare film coating liquid is used After the solvent is evaporated, the resin 3 and the light-scattering particles 4 gradually settle to form the anti-glare film coating 2. Since the solvent of the anti-glare film coating liquid evaporates, the force between the solvent and the resin 3, the solvent and the light-scattering particles 4, and the resin 3 and the light-scattering particles 4 is complicated, so that the light-scattering particles 4 are dried. It is then randomly distributed in the anti-glare film coating 2. However, the above technique cannot control the distribution of the light-scattering particles 4 in the anti-glare film coating 2, and the haze of the anti-glare film cannot be effectively controlled. [0004] For example, "Anti-glare hard coat film and process for producing the film", U.S. Patent Publication No. 6217176, "Antiglare film and use thereof", and US Patent Publication No. 6613426B2, Veryy Fine apti-glare hard coat film" 'Anti-glare film and process for producing same thereof", US Patent Publication No. 6,896,960, 'Anti-glare hard coat film', US Patent Publication No. The contents disclosed in "Anti_ glare film and process for producing the same" of 7 〇 33638 B2, which disclose various methods or materials for producing anti-glare films, which mainly utilize the size and number of light-scattering particles and resin The thickness of the layer is used to control the haze of the anti-glare film. In addition, as in the Republic of China Patent Publication No. 557363, the 'anti-glare film', the Republic of China Patent Publication No. 590886, the method of forming an anti-glare anti-reflection film"中099122070 Form No. A0101 Page 4 of 19 Page 0992038860-0 201202752 [0005] China National Patent Announcement No. Μ252022, 'No.+,, now optical anti-glare film,', which also discloses methods and materials for controlling the haze of the anti-glare film by using the light scattering particles, the small amount and the thickness of the resin layer. Due to the limitations of the coating equipment, it is not easy to adjust the coating process. Therefore, if an anti-glare film with different haze is to be produced, the formulation of the anti-glare coating liquid needs to be redesigned, and it is not easy to consider due to factors such as wet film thickness, optical coating liquid dryness, and the compatibility of light-scattering particles and resin. An anti-glare film with a designed haze value inside and outside is produced. 0 [0006] Ο as disclosed in Japanese Patent No. 2006-088643, the process of embossed roll" and the US Patent No. 7008066B2 "Antiglare film process f〇r producing the same, and display device using antiglare fiim" The technology 'true sun makes the surface of the coating film form a concave-convex microstructure by embossing roller to achieve anti-glare or anti-reflection effect. Although the above technology can produce anti-glare film with different haze, however, for different The manufacture of haze anti-glare film must be combined with different scraping rollers to cause:: the increase in the original. In addition, the above method can only change the external haze, and can not effectively adjust the internal haze. [0007] [Summary] The main object of the present invention is to solve the problem that the conventional technique cannot effectively control the inside and outside haze of the anti-glare film separately. Another object of the present invention is to provide an anti-glare film which is simple in preparation and low in cost. The present invention provides an anti-glare device with different internal and external haze, comprising a transparent substrate and a coating solution coated with an anti-glare film.

In addition, the present invention also provides a method for producing an anti-glare film with different internal and external haze, comprising five steps of W-S5, as follows Listed: 51: Wash a transparent substrate, dry for use; 52: Prepare a light-scattering particle; 53: Prepare-anti-ductive light-scattering particles, modify the silk particles prepared by step (4) by surface modification Paired tree stalking and opposite characteristic light scattering particles; 54: Fabrication - anti-glare film coating 16, the light scattering particles prepared in step 52 and step illusion and the anti-hiding scatter test The anti-glare coating liquid is obtained by adding the anti-glare coating liquid prepared in the step S4; and the anti-glare coating liquid prepared in the step S4 is applied to the transparent substrate of the step si and being dried to complete the production of the anti-glare film. In particular, the hybrids of the step Wei towel may be pro-resin light scattering particles or Resin silk particles, and * must first prepare the resin light scattering particles or first prepare the light scattering particles and the inverse characteristic light scattering particles refer to the resin light scattering particles which are different from the characteristics of the light scattering particles prepared first or According to the above description, the present invention can be manufactured by adjusting the ratios of the inner and outer hazes of four glare films by adjusting the ratios of the resin-light-scattering particles and the resin-based light-scattering particles provided in the resin.
