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 colour displays using ink jet printing.
The displays were produced at CDT's Technology Development Centre in the UK, and feature a resolution of 1280 x 768 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 ink jet printing is the best approach to achieving scaleability 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 Corporation, a company in which CDT currently has a 50% holding.
For CDT, Dr David Fyfe, CEO commented: "We are delighted at the rate of progress being demonstrated by these latest displays. 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."

I'd like to know where these are operating in the UK. The report is notably light on this. I wonder why?
