A 155 inch OLED Display? Really? Yes because Mitsubishi use small 384x384mm parts to realize a 155 inch OLED Display.
The japanese company showcased the Diamond Vision at Ceatec-2009 and Ise-2009. The goal is to sell this kind of products for the digital signage market at public spaces like train station, underground station, airports etc. The important technical details are that a standard module have 384x384x99mm with a pixel resolution of 128×128 pixels. The maximal brightness is about 1.200 cd/m² which is more than a standard LCD TFT Display. The next big thing is that you are not limited in the size, so you can ramp up very large screens. The pixel densitity is about 111,111 pixels / m2 this is enough for that kind of market. The lifetime of the display is only 20.000 hours of normal operation, no word if you set the brightness to the maximum. You can control the wall via Mitsubishis video controlling technology. Mitsubishi says that the viewing angles reach 80 degrees that kind of product is only for indoor usw says Mitsubishi. With this kind of modules it is possible to make any size or shape it is also possible for rounded surfaces because the module has only 99mm depth. Tohoku Pioneer and Mitsobishi are producing the OLED panels, each pixel consists an anode and cathode separated by the Organic layer.
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. The price from one square meter with 3mm pixel pitch costs about 35.000 euros. A LED Videowall costs about 60.000 Euro per square meter. The Panels are PMOLED Displays and not AMOLED (Active Matrix) so this kind of technology can produced cheaply compared to Active Matrix Organic light emitting diode technology.
In 2011 Mitsubishi sells a 6 meter globe with 96 x 96mm OLED Modules at National Museum of Emerging Science and Innovation in Tokyo, Japan. Geo-Cosmos are hanging 18 meters from the floor and feature 10362 panels.
At ISE-2011 Mitsubishi showcased a curved version from this concept, with a radius of 917,15 mm with a pixel pitch of 3mm. With this pixel pitch they can achieve a 1920×256 pixel resolution. This version of Diamond product has 128×128 pixel per module the brightness 1200 cd/m²
