Abstract

Backlight unit；sub-wavelength grating；Light bar；ultra-precision machining；Roll-to-roll imprinting process Engineering (all)
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.
