Document Type and Number:
Japanese Patent JP7317997
Kind Code:
B2
Abstract:
A light source configured to provide output light having a bifurcated emission pattern includes an optical emitter configured to emit light and a emission control layer. The emission control layer includes a first plurality of light-blocking elements spaced apart from one another in a vertical direction at an output aperture of the light source and a second plurality of light-blocking elements displaced from the output aperture and interleaved with the first plurality. The emission control layer is configured to transmit a portion of the emitted light through gaps between the light-blocking elements to provide the output light having the bifurcated emission pattern in the vertical direction. A multiview backlight includes the light source along with a light guide and an array of multibeam elements to provide a plurality of directional light beams using the output light having the bifurcated emission pattern.
