    • PROBLEM TO BE SOLVED: To provide an optical film for controlling angular characteristics of a display.
      SOLUTION: A light-interference display device is provided by having an external film 605 using a plurality of structures that reduce the field of view of the display. For example, non-imaging optical elements, such as baffles 603 or compound parabola focusing devices, can be included. The baffles, for example, can include a plurality of surfaces which are arranged in a grid to be aligned in a vertical direction. The baffles are opaque or have reflectiveness. Therefore, these vertical surfaces 610 can substantially block light from exiting the light-interference display device in a substantially non-vertical direction 607. However, the vertical surfaces allow light directed in a substantially vertical direction to exit the display. The non-imaging optical elements, for example, compound parabola focusing devices, redirect light from large incident angles to more vertical angles towards the display.

    • 要解决的问题:提供一种用于控制显示器的角度特性的光学膜。 解决方案:通过使用减少显示器的视野的多个结构的外部膜605来提供光干涉显示装置。 例如,可以包括非成像光学元件,例如挡板603或复合抛物面聚焦装置。 挡板例如可以包括布置成格栅以在垂直方向上对准的多个表面。 挡板是不透明的或具有反射性。 因此,这些垂直表面610可以基本上阻挡来自基本上非垂直方向607的光干涉显示装置的光。然而,垂直表面允许在大致垂直方向上指向的光离开显示器。 非成像光学元件,例如复合抛物面聚焦装置,将来自大入射角的光重定向到更大的垂直角朝向显示器。 版权所有(C)2011,JPO&INPIT
