Module-based OLED, scalable screen allows flexible applications in size, shape.

Mitsubishi Electric Corporation announced today that it will launch “Diamond Vision OLED,” the world’s first, large-scale display system in the 100-inch and above range that uses organic light emitting diode (OLED) as its light source. Sales will begin worldwide on
September 21. One square meter from the OLED Diamond Vision costs about 35.000 Euros.
The Diamond Vision OLED, designed for indoor use, delivers seamless, vivid images using Mitsubishi Electric’s newly developed video controlling technology. The screen offers wide horizontal and vertical viewing angles reaching approximately ±80 degrees, and features a maximum brightness of 1,200cd/m² and
twice high contrast compared to our LED product, making it suitable for installation in relatively brightly-lit areas such as commercial facilities, stations and airports.
Built by connecting a number of standard modules each measuring 384mm both in height and width and weighing eight kilograms, the Diamond Vision OLED is scalable and can be designed to flexibly form a certain size or shape, even against rounded surfaces. The screen’s 99mm depth enables it to be installed in limited spaces such as narrow paths and station concourses.
The product’s OLED device, jointly developed between Mitsubishi Electric and Tohoku Pioneer Corporation, creates light by a process of electro-luminescence (EL). Each pixel consists of an anode and cathode separated by a thin, organic membrane.

Mitsubishi Electric’s Diamond Vision OLED will be showcased at the company’s booth at CEATEC JAPAN 2010, scheduled to be held from October 5-9 at Makuhari Messe in Chiba, Japan.

Background
Digital signage systems have recently become widely used around the world to show timely information and advertisements in shopping malls, passenger terminals and public facilities. The installation of such systems must increasingly take into account a variety of spacial and physical limitations and restrictions, as well as
excessive natural light conditions. As a result, there is an increasing demand for scalable displays that can flexibly be formed into the required shapes and sizes while maintaining a high level of picture quality and visibility.

At CEATEC JAPAN 2009, Mitsubishi Electric unveiled the world’s first prototype model of a large-scale OLED display with a 155-inch screen, developed through utilizing the company’s large-scale display technology accumulated from the development of Diamond Vision screens installed at numerous sports stadiums and other public facilities.

Mitsubishi Electric show  a 155-inch sized OLED Television display, which consists of small sized OLED parts (estimated size is a 10x10cm square unit) at the Ceatec 2009. The large scale OLED display has been developed for digital signage and monitors placed at public spaces.

Thanks to the  modular system the large screens can be curved in large installations, to follow the curvature of a building, wall or wherever else it’s installed. Because  OLED technology used in the creation of this system, brightness is said to be three times greater than in regular LCD TVs. Organic compounds in the pixels degrade over time, however, with the set’s life rated at 20,000 hours of continuous use.

The pixel pitch is about 3mm. But when watched from a distance of more than 2m, the display looked fine enough for me. The pixel pitch of large-size LED displays is normally 4 to 6mm. There are some LED displays with a pixel pitch of 3mm, but they use many LEDs and are too expensive to become popular, Mitsubishi Electric said.
