Abstract

The invention provides a high-scattering ultrathin light guide plate and a manufacturing method thereof, including the following steps that: the light guide plate has a body; a bottom surface is arranged below the body; transparent material is daubed on the body by a roller wheel and is formed into a plurality of light outlet bulges after solidifying forming; the body is cut into an appropriate size according to requirements to form the light guide plate; the bottom surface is formed into a reflection convex point and a reflection groove face through synchronous solidifying. In addition, the invention also provides a high-scattering ultrathin light guide plate made through adopting the method.

Description

Technical field [0001] The invention relates to a high-scattering ultra-thin light guide plate and a manufacturing method thereof, in particular to an innovation in the preparation of polymer materials used in the fields of high-scattering optical penetration requirements such as liquid crystal displays, notebook computers, PDAs, mobile phones, photoelectric materials, etc. . Background technique [0002] The backlight module of the LCD (liquid crystal display) is composed of a light source, a light guide plate, a diffuser, a Prism sheet, and a reflector. The microstructure converts a point (or line) light source into a surface light source, achieves the provision of a high-brightness uniform light source, and guides the scattering direction of the light to improve the light utilization rate and ensure the uniformity of the panel brightness. Therefore, the design of the light guide plate And manufacturing has a huge impact on the backlight board, which is the main technology and ...
