CDT demonstrates milestone in OLED technology

Cambridge Display Technology (CDT) has announced the development of a 14-inch full color display by using inkjet printing. Based on polymer light emitting diode (P-OLED) display technology, the new display is a vast improvement over previous displays by the company that were mostly in the range of 5.5-inches in size. By developing the new 14-inch color display by using inkjet printing, the company is claiming to have made a major breakthrough in P-OLED technology.

The new display promises a very high range of resolution — 1,280 x 768 pixels, which is equivalent to almost three million sub-pixels. The active matrix panels in the display use an amorphous silicon backplane, and have been made by making use of a multi-nozzle approach – the first of its kind. The WXGA+ panels were produced using printers from the Litrex Corporation, a company in which CDT currently has a 50% holding.

After the development of the new display, the company has put forward its observation that that multi-nozzle inkjet printing is the best approach in manufacturing high-quality P-OLED displays. David Fyfe, CEO, CDT commented today, “It is not easy to produce high-quality products when manufacturing a display design for the first time and in very small quantities, so the evident viewing quality and freedom from major defects demonstrated by these panels is especially encouraging.”
