Title:
回折バックライトを製造する方法
Document Type and Number:
Japanese Patent JP7333828
Kind Code:
B2
Abstract:
Diffractive backlight fabrication employs a diffraction grating to scatter light from a light guide and define a reflective island that is aligned with the diffraction grating. A method of fabricating a diffractive backlight includes providing the light guide having the diffraction grating, diffractively scattering guided light out of the light guide using the diffraction grating to selectively expose photoresist and provide an opening in the photoresist, and depositing a reflective material into the opening to form a reflective island that is aligned with the diffraction grating. A reflective diffraction grating element of the diffractive backlight includes the diffraction grating and reflective island.
