NEW MANUFACTURING METHOD FOR LIGHT GUIDE OF PMMA

摘要

The market share of LCD in display devices is now growing rapidly. Especially many LCD makers have had their efforts to develop the LCD module not only with thinner and wider panel but also with cost competitiveness. In this study, we propose a low-cost alternative manufacturing method for the light guide of PMMA, which is one of important components in the backlight system of the LCD module. This manufacturing method is called the direct surface forming (DSF), which may be also called the well-known hot embossing. We present the results of this manufacturing method in terms of dimensional accuracy, productivity, etc.
