Mitsubishi Electric displays a 155-inch sized OLED 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.
The screen is three times brighter than regular liquid crystal display TVs.
Another advantage of the screen’s modular design is that there is no limit to how big the display can be made. The size of a video screen made using the displays is only limited by the resolution of the image, such as a high-definition video. But for advertising or other application, there’s no limit to how big the screen can be, Terazaki said, saying it would theoretically be possible to cover an entire city with a single display.
Mitsubishi said the Diamond Vision OLED screen is expected to have a lifespan of 20,000 hours of normal operation.
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.
