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 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.
