Abstract
Предложен объединенный оптический узел, позволяющий предотвратить образование складок, отклонений и деформации, и который может быть выполнен более тонким. Сформирован набор 10, в котором диффузионная пластина 11, диффузионный лист 12, пленка 13 с линзами и отражающий поляризационный лист 14 уложены слоями, и сюда включена упаковочная пленка 20, закрывающая набор 10. Упаковочная пленка 20 включает в себя пленку 21 на стороне падения света и пленку 22 на стороне излучения света. Пленка 21 на стороне падения света и пленка 22 на стороне излучения света закрывают набор 10 с приложением к нему силы усадки и изготовлена из материала, имеющего по меньшей мере одну из характеристик усадки под действием тепла и свойств растяжения. Когда источник света расположен на стороне одной грани объединенного оптического узла 20, блок 23 сегментации изображения источника света включен в область 21А падения света, в которую поступает свет от источника света.
