Abstract: 【解決手段】マルチビーム回折格子ベースの背面照明は、ライトガイドと、ライトガイドの表面のマルチビーム回折格子とを有する。ライトガイドは、光源からの光を導波する。マルチビーム回折格子は、回折カップリングを用いて導波光の一部分をカップリングして外へ出し、このカップリングして外へ出された部分を、異なる主極大角度方向を有する複数の光ビームとしてライトガイドから離れるように方向付ける。【効果】異なる主極大角度方向を有する複数の光ビームを使用して、3次元(3D)情報を表示することができる。例えば、マルチビーム回折格子により生成された、異なる方向に向けられた複数の光ビームは、変調され、「裸眼」3D電子ディスプレイの複数の画素として作用することができる。【選択図】図5

Abstract: A method of forming a large-area nanoimprint mold master is provided. The method comprises positioning a plurality of sub-master tiles on a rigid planar substrate. Each sub-master tile of the sub-master tile plurality has a nanoscale pattern and represents a subsection of the large-area nanoimprint mold master. The method further comprises adhering the plurality of sub-master tiles to the rigid planar substrate. The positioning determines a distance between a nanoscale feature of the nanoscale pattern on each sub-master tile of a pair of adjacent sub-master tiles. The distance has microscale positioning tolerance. Also provided are a large-area nanoimprint mold master and a method of large-area nanoimprint lithography.

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.

Abstract: Fabricating a diffractive backlight employs a universal grating and selects a portion of the universal grating using a reflective island to define a grating element, a reflective diffraction grating element of the diffractive backlight including the grating element and the reflective island. A method of fabricating a diffractive backlight includes forming the universal grating, forming the reflective island, and selecting a portion of the universal grating using the reflective island to define the grating element. The method of fabricating a diffractive backlight may include forming the reflective island on a light guide surface and forming the universal grating over the reflective island. Alternatively, the method of fabricating a diffractive backlight may include forming the universal grating on the light guide surface and forming the reflective island over the universal grating.

Abstract: A directional backlight is disclosed. The directional backlight has a directional backplane that has a plurality of directional pixels to scatter a plurality of input planar lightbeams into a plurality of directional lightbeams. Each directional lightbeam has a direction and angular spread controlled by characteristics of a directional pixel in the plurality of directional pixels. A modulation layer having a plurality of modulators modulates the plurality of directional lightbeams. The directional backlight can be used to generate a 3D image with multiple views by specifying the characteristics of the directional pixels in the directional backplane.
