44.5: Roll-to-Roll UV Embossing-Process-Based Sub-Wavelength Gratings for Backlight

Authors


Abstract

A sub-wavelength gratings (SWG) patterned light bar (LB) was proposed to reduce the coupling length and improve the white color balance for display applications. In this design, we used ultra-precision machining and a roll-to-roll imprinting process based UV resin process to make SWG for display applications.
