| New electron transport material has lower toxicity, lower voltage, higher electroluminescent efficiency, longer lifetime and lower voltage drift.
OLED-T is claiming significant technical and performance benefits for its new E278ST organic electron transport material.
OLED displays are manufactured from a sandwich of different materials including the electron transport layer.
This layer is critical to the efficiency, voltage, and lifetime of the total display based on the electron conductivity performance of the material.
E278ST has been developed as a like-for-like replacement in manufacturing lines for aluminium quinolate (Alq3), the electron transport layer most commonly used throughout the OLED industry.
E278ST provides significant technical and performance benefits compared with Alq3.
The new electron transport material has lower toxicity, lower voltage, higher electroluminescent efficiency, longer lifetime and lower voltage drift.
In customer trials, OLED-T has demonstrated a 2x increase in device lifetime and a 25% reduction in device voltage.
A fluorescent red devices voltage was reduced from 8 to 6V at 500cd/m2 and showed a 20% power efficiency improvement.
Voltage drift was reduced by 25% over the first 500h of operation.
The new material is organic and contains no metals.
The new material complements OLED-Ts already strong OLED material portfolio.
E278ST offers superior performance as an electron transport material in both passive matrix and active matrix OLED displays compared with existing materials , says Myrddin Jones, CEO, OLED-T.
It can be used as a direct replacement and upgrade path for aluminium quinolate, ensuring that display manufacturers can gain benefits using existing manufacturing processes.
OLED-T will begin customer sampling of E278ST from the second quarter of 2008 and will commence volume production from the fourth quarter of 2008.
The new material complements OLED-Ts already strong OLED material portfolio.
OLEDs are developing into an important market for the display industry as well as the chemical industry.
Materials are estimated to make up 20% of the value of the OLED supply chain.
The worldwide flat panel display market was worth US $70 billion in 2006 and is forecast to rise to $100 billion by 2010 according to display industry analysts.
OLED is the fastest growing display technology outside LCDs, and by 2010 it is predicted that the sector will be worth more than US $2.5 billion.
