Development of a Multilayered Optical Diffusion Sheet Using Microcellular Foaming Technology

Abstract

The superior optical performance of a sheet developed using microcellular foaming technology is demonstrated through the development and commercialization of a reflector. In this study, the cell morphology characteristics of reflectivity, transmittance, and haze were analyzed to develop diffusion sheet. A basic concept of a multilayered diffusion sheet was derived using axiomatic design, and the design was tested and validated using a microcellular foaming batch process. Diffusion sheet transmittance and haze values were compared with commercialized products. The results show the multilayered diffusion sheet manufactured using a microcellular foaming process increased transmittance by 40% compared to that of existing products.
