CAMBRIDGE DISPLAY TECHNOLOGY ANNOUNCES  MAJOR NEW DEVELOPMENT IN DISPLAY TECHNOLOGY
Total Matrix Addressing (TMA™) Extends Viability of Passive Matrix OLED Displays By Reducing Power Consumption, Increasing Panel Size

Cambridge, United Kingdom - November 15, 2006 - Cambridge Display Technology (CDT) (NASDAQ:OLED) today announced a major new development in OLED display technology: Total Matrix Addressing, or TMA™.

Prior to TMA, large OLED displays have only been feasible by using active matrix (AM) technology incorporating an expensive thin-film transistor (TFT) layer.  Passive matrix (PM) displays, which are driven by cheaper external chips, have been restricted to smaller screen sizes.  TMA is a technology which potentially can be incorporated into driver chips to bring active matrix capabilities to passive matrix displays.  TMA reduces power consumption and enhances panel lifetime for a given pixel count in passive matrix displays.  Measurements on small passive matrix displays that incorporated the TMA solution, demonstrated at least a 50% reduction in power consumption or exhibited double the display luminescence at the same power consumption.
