指向性彩色滤光片和裸眼3D显示装置
摘要：
本发明提供了一种指向性彩色滤光片和裸眼3D显示装置，包括彩色滤光片和指向性功能结构层；彩色滤光片包括多个滤光单元，每一滤光单元包括至少三个不同颜色的滤光子单元；指向性功能结构层包括多个结构单元，每一结构单元与一滤光单元对应设置；每一结构单元包括至少三个结构子单元；每一结构子单元与一滤光子单元对应设置；每一结构子单元包括多个纳米衍射光栅；同一结构子单元内的纳米衍射光栅的周期和取向角不同，从而不会出现同一纳米衍射光栅出射两种颜色的光，导致光线串扰的问题，且该指向性彩色滤光片在技术上较容易实现，使得本发明提供的基于指向性背光技术的无视觉疲劳的多视角的裸眼3D显示装置较易得到实际应用。
摘要（英）：

A directive color filter and a naked-eye 3D display apparatus are provided. The directive color filter includes a color filter and a directive functional structure layer. The color filter includes multiple light filtering units, and each light filtering unit includes at least three light filtering sub-units with different colors. The directive functional structure layer includes multiple structure units, and each structure unit and one light filtering unit are arranged correspondingly. Each structure unit includes at least three structure sub-units. Each structure sub-unit and one light filtering sub-unit are arranged correspondingly. Each structure sub-unit includes multiple nano diffraction gratings.
