Abstract

Описано создающее изображение устройство направленной подсветки, включающее массив источников излучения и систему управления, выполненную с возможностью обеспечивать изменяемое распределение световых потоков, масштабированных обратно пропорционально по ширине, связанной с соответствующими источниками излучения в боковом направлении, по массиву источников излучения. Распределением силы света выходных оптических окон можно управлять для получения желаемых распределений светимости в плоскости окна автостереоскопического устройства отображения, устройства направленного отображения, работающего в широкоугольном 2D-режиме, режиме обеспечения конфиденциальности или режиме с низким энергопотреблением. Также можно повысить качество изображения и снизить энергопотребление.
