Front lighting assembly light guide and production method thereof

摘要

A front lighting assembly light guide, comprising a light guide and a plurality of microstructures thereon. The light guide is laid on a front surface of a reflective LCD panel. A light source is placed at one end of the light guide. The plurality of microstructures are placed on a front surface of the light guide, deflecting light from the light source towards the LCD panel, illuminating the LCD panel. The plurality of microstructures are located isolated from each other, allowing to be distributed on the surface of the light guide at a spatial density according to the spatial intensity distribution of light from the light source, the density of microstructures increasing with lower light intensity. Thus uniform illumination of the LCD panel is achieved.
