Shinoda Plasma Creates Flexible Plasma Display

At the FPD International show in Yokohama, Japan, Shinoda Plasma Co. Ltd. demonstrated a large-format flexible plasma display panel measuring 1 x 3 m. The plasma display has a thickness of only 1 mm, and is designed for large-scale digital signage used at public venues such as museums and subways.

Shinoda Plasma demonstrated a flexible plasma display panel that is visible from both front and rear.

Shinoda Plasma Co. Ltd. (Kobe, Japan) has developed a large-format flexible plasma display measuring 1 × 3 m, and demonstrated the screen recently at the FPD International show in Yokohama, Japan. The plasma display has a thickness of only 1 mm, and is designed for large-scale digital signage used at shopping malls, airports, exhibition halls, sport arenas and other public venues.

A unique structure of the display consists of massive arrays of glass tubes, as well as X and Y electrode films coated with indium tin oxide (ITO). A glass tube measuring 1 mm in diameter and 1 m long is filled with xenon-neon gases. Transparent X and Y electrode films sandwich the glass tube array. Fluorescent layers of red, green and blue are coated inside the tubes to emit R, G and B colors. The three color tubes form a single pixel, resulting in a relatively course resolution. Applying 100-200 V at the X and Y electrodes generates a plasma, and electrons collide with the fluorescent films to emit light.

The screen’s image is visible from both the front surface and rear because the panel is transparent. The company said the plasma display is flexible because the glass tube is so long and thin that it bends easily.

The demonstrated display panel consists of three modules, each measuring 1 × 1 m, with 960 × 360 pixels overall. The display is 1 mm thick and weighs 3.6 kg. Power consumption is 400 W typical, 600 W max.

Shinoda Plasma is an R&D company funded in 2005 by Tsutae Shinoda, who spun out the company from Fujitsu Ltd. Shinoda said the company’s vision is to create a large-screen video culture.
