Embodiment Construction

[0027] The invention is to provide a light-enhancing diffusion film which can be used in a backlight module. The light-enhancing diffusion film is arranged on the light guide plate of the backlight module, and when light passes through the light-enhancing diffusion film, the light passing through the light-enhancing diffusion film will diffuse and enhance the light to become highly uniform light. By using this light-enhancing diffusion film, the use of diffusion sheets and prism sheets in traditional multilayer optical films can be reduced, and the brightness quality of the backlight module can be improved.

[0028] Such as image 3 As shown, the light-increasing diffusion film according to the preferred embodiment of the present invention is applied to a partial cross-sectional view of a lateral backlight module. in image 3 Among them, the lateral backlight module 30 at least includes a light guide plate 31, a reflective sheet 32, a light source 33 and a light-enhancing diffusion ...

Abstract

The film is formed with polyethylen terephthalate plastic, light bleacher and polish. The light bleacher is plane structure in conjugate double bond with at least one electron supply group and polish is a type of methyl silicone oil. The thickness range of polish diffusion film is from 0.05 mm to 0.6 mm and the film is disposed on light guiding plate by means of static attachment or sticking on with black glue, the light is become high uniformity light after it is polished through the polish diffusion film.

Description

Technical field [0001] The invention relates to a light-enhancing diffusion film, in particular to a light-enhancing diffusion film that can be used in a backlight module. Background technique [0002] With the rapid progress in the manufacturing technology of Thin Film Transistor Liquid Crystal Display (TFT-LCD), as well as its advantages of lightness, thinness, power saving, and non-amplitude radiation, liquid crystal displays (LCD) It is widely used in various electronic products such as mobile phones, personal digital assistants (PDA), notebook computers, digital cameras and camcorders. [0003] Such as figure 1 As shown, it is a partial cross-sectional view of a conventional side-view backlight module. in figure 1 The backlight module 10 at least includes a light guide plate 11, a reflective sheet 12, a light source 13, a multilayer optical film 14 and a frame 15. The light guide plate 11 has a light emitting surface 11a, a lower surface 11b, and an upright side surface 11...
