42‐3: Novel Transparent Screen Combined with Light Guide System

Abstract

We have successfully developed a novel transparent screen leading to a new AR display without unexpected light, combining with a light guide system. We believe this novel AR display could expand applications into show window and vehicles.

50‐3: Novel Bright Rear‐Projection‐Type Transparent Screen Using Tilted Cholesteric Liquid Crystals

“…In our previous study, we found there was a relationship between the tilt angle of cholesteric liquid crystals and the surface energy acting in polar angles [6]. In this study, we designed the surface energy at the air interface and at the substrate interface independently to achieve different tilt angle at the air interface and at the substrate interface (φ sub > φ air ).…”
