Abstract

Изобретение относится к методам и устройствам для управления интенсивностью и направлением света, исходящего от независимого источника, в том числе к конструктивным взаимосвязям оптических устройств в частности для систем подсветки цветных жидкокристаллических дисплеев. Способ включает перенаправление излучения от источников с помощью линз (рефлекторов). Излучение перенаправляют на светорассеивающую подложку и формируют равномерно освещенные отрезки, обеспечивающие в свою очередь равномерное освещение дисплея Техническим результатом использования данного изобретения является улучшение световых характеристик дисплеев, таких как эффективность, однородность освещенности, а также снижение стоимости системы за счет использования линз (рефлекторов) с одной рабочей поверхностью и меньшего количества высокоэффективных источников света (светодиодов).
