   As we have written, the company Toshiba Matsushita Display Technology (TMD) in conjunction with Idemitsu Kosan Company since autumn 2009, will maintain production of 2, 5 - inch panels organic electroluminescent (EL-displays). Now, here are details on this interesting technology that allows production of displays with longer life, ultra power and improved performance.
EL-displays (electroluminescent) of TMD will be made on technology, which uses organic LEDs on small molecules (SM-LED). Initially, such a matrix made using vacuum deposition, but recent technology development mikropechati allowed to use in the production of SM-LED-display technology similar to the jet printing. Moreover, this method is much cheaper costs.
As a result, it has been possible to produce smaller EL-displays for mobile devices with a term of life 30 times greater than other models life displays of TMD and one-tenth of their energy consumption. As an example was manufactured 2, 2 - inch QVGA (240x320 pixels) display with a power of 100 MW, 200 cd/m2 brightness and a term of life 60 000 hours.
Because the layer of organic crystals, formed on a glass substrate, has good properties of light - EL-displays have better indicators of contrast and clarity of the image as compared with conventional OLED-displays. These displays can also realize the display of dynamic scenes films without blur and with a wide viewing angle. Furthermore, organic EL-displays require fewer resources to create them because they did not need the backlight various peripheral components.
So far, the TMD and Idemitsu Kosan may produce only small displays used in mobile devices only. But perhaps in the near future joint work of these companies will enable them to produce EL-displays with large diagonal.
