29.1: Polarizer-Free Reflective LCD Combined with Ultra Low-Power Driving Technology

We have developed a novel reflective LCD without polarizers, which is sure to provide excellent visibility (reflectance = 50%, CR = 10:1). Moreover, we have also achieved extremely low power consumption of 10 microwatts to introduce low frequency driving (less than 1Hz) without flicker and image sticking. These characteristics were realized to combine pixel memory circuit and new PNLC material.

80.2: 60‐inch Highly Transparent See‐through Active Matrix Display without Polarizers

For the first time, we have developed a 60-inch diagonal size see- through display using polymer network liquid crystal (PNLC) technology. The color display system by combination of the see- through display and a projector enables distinguishing eye-catch effect. It creates new application of displays, such as information display, digital signage and substitution of window.

P‐135: A High Reflectivity Fluorescent Guest‐Host Polymer Network LC Color Display

We have developed a novel bright reflective color display, which combines the polymer network liquid crystal (PNLC) containing dichroic fluorescent dyes and the ultra-low-power driving technology. The high reflectance, 60% at the maximum, was achieved by enhancement of the external light emission from the dyes due to the light-scattering effect of PNLC.
