P-189: Patterned Vehicular-Window Screen for 3D Pico-Projector Applications

摘要

Tinted vehicle windows are commonly used for different applications among which are providing privacy, reducing transmitted sun light in hot climates and sometimes just for aesthetics among other uses. The herein reported work was geared towards retaining these traditional aspects of tinted vehicle windows while adding a new display aspect component for custom display applications. We applied a low cost dual purpose diffusely transmitting and diffusely reflective pattern onto a low cost PVC plastic film. This custom pattern printed film was then applied to both transparent and conventionally tinted vehicle windows glass to observe the change in image quality projected onto them using a low cost 45 lumens Liquid Crystal on Silicon [LCoS] Pico projector [1],[2] made in China. Images were observed and recorded under the same ambient light environment. The results showed significantly improved visibility on the vehicle windows augmented with our custom pattern printed film compared to those without the custom patterned film where the images were literally invisible. In addition we added a 3D projection prism screen to enable glasses-free 3D perception for vehicle interior and exterior applications.
