Cambridge Display Technology Demonstrates Milestone in OLED Displays

via PRNewswire

CAMBRIDGE, England, Nov. 3 /PRNewswire-FirstCall/ -- Cambridge Display Technology (CDT) has announced another important step in the development of polymer light emitting diode (P-OLED) display technology with the production of a number of 14-inch full-color displays using inkjet printing. The displays were produced at CDT's Technology Development Centre in the UK, and feature a resolution of 1280x768 pixels x RGB, equivalent to almost three million sub-pixels, or over 30 million ink jet drops.

The active matrix panels use an amorphous silicon backplane, and were made using a multi-nozzle approach -- up to 128 nozzles -- with no interlacing, and are believed to be the first of their kind ever produced.

The development strengthens CDT's view that multi-nozzle inkjet printing is the best approach to achieving scalability and a low TAC time in the manufacture of high quality P-OLED displays.

Earlier this year, CDT demonstrated several 5.5-inch displays, and the latest 14-inch displays are part of a continuing program to develop both the underlying P-OLED technology and the means of manufacture. The WXGA+ panels were produced using printers from the Litrex Corp. (Pleasanton, CA), a company in which CDT currently has a 50 percent holding.
