Technology (CDT) (Nasdaq: OLED) has joined forces
with ILFORD Imaging Switzerland, in a project that
promises to pave the way for more optically efficient
display devices in the future.
All displays produce
more light than is actually seen by the user, due
to internal losses in the display itself. By increasing
the proportion of observed light, (the ‘optical efficiency’),
display devices can be made brighter for a given energy
input, or energy consumption can be reduced for a
given brightness. This is especially valuable where
power efficiency is critical such as in mobile devices
such as phones and PDAs.
ILFORD is a leading
manufacturer of precision coated, ink jet printing
consumables, and has discovered that certain nanoporous
structures have potentially valuable properties when
applied to polymer light emitting diode (PLED) displays.
The new materials,
when integrated into a display device, have optical
properties which help to transmit light which would
otherwise be trapped and lost. The project - which
will complete its initial proof-of-principle phase
by the end of the first quarter of 2005 - is designed
to evaluate and quantify the performance advantages
that may be available from this novel approach.
Work is ongoing and centred at CDT’s Technology Development
Centre near Cambridge, UK, where much of the work
is carried out in developing and preparing PLED technology
Cambridge Display Technology is a pioneer in the development
of light emitting polymers (PLEDs) and their use in
a wide range of electronic display products used for
information management, communications and entertainment.
PLEDs are part of the family of organic light emitting
diodes, or OLEDs, which are thin, lightweight and
power efficient devices that emit light when an electric
current flows. PLEDs offer an enhanced visual experience
and superior performance characteristics compared
with other flat panel display technologies such as
liquid crystal displays. Founded in 1992, the company
is headquartered in Cambridge, UK and listed on the
US Nasdaq stock exchange under the symbol ‘OLED’.
