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.

16.2: Influence of rough surface upon optical characteristics of reflective LCD with a polarizer

We have developed bright 260,000-color “High Reflective TFT (HR-TFT)” liquid crystal display (LCD) with diffused “Micro Reflective Structure (MRS)” inside a panel. In this paper, influences of rough surface upon the optical characteristics of the reflective type LCD are discussed.

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.

A 40‐in. (1‐m) diagonal direct‐view TFT‐LCD by seamless‐connection technique

We have realized the worlds largest-size 40-in.-diagonal TFT-LCD by seamless panel-connection technology. This technology can easily make a large display degrading affecting the advantages of TFT-LCDs. In this paper, we discuss several techniques for a seamless connection.

P‐149: Super Reflective Color LCDs Being Able to Display Moving Images without Polarizers

Novel reflective color LCDs without polarizers have been developed with using PDLCs and retro-reflectors. By eliminating polarizers, brightness of our newly developed LCDs has been increased by 51% compared to conventional reflective LCDs, and there still is much room to be improved. Whats more, our LCDs can be displayed not only bright text images but also color moving images on, since their response time and driving voltage are significantly fast (63ms) and low (5.5 volts).

40.5: Invited Paper: Super Reflective Color LCD with PDLC Technology

A novel reflective color LCD without polarizer has been developed with using PDLC and retro-reflector. Bright color images including moving images are available with utilizing ambient light. Our novel LCD will create a new application area such as electronic paper.

Super‐reflective color LCD with PDLC technology

— A novel reflective color LCD without polarizers has been developed using a PDLC film and a retro-reflector. Bright color images including moving images are achievable with ambient light. This novel LCD will enable the new application area of electronic paper.

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.
