Abstract

Micro pattern is applied to the light guiding plate(LGP) to enhance the uniformity of the brightness of the LCD. The micro cones are molded in intaglio on the surface of the LGP. The surface roughness of each cone was 40nm and 38nm in negative and positive die for laser ablation. In chemical etching, the surface roughness was 25nm, 24nm in negative and positive. And the surface roughness of negative and positive dies were 4nm and 5nm for LIGA-reflow process.
