Host material improves OLED displays
A new patented host material for OLED displays claims significant performance benefits compared with existing alternatives
OLED-T has developed a new patented host material for OLED displays that delivers significant performance benefits compared with existing materials. The host layer is a crucial layer in the make-up of an OLED display as it impacts its performance including efficiency and lifetime. The new OLED-T material, called E746, is targeted as a direct replacement and upgrade path for aluminium quinolate (Alq3), the host material most commonly used throughout the OLED industry.

EI-101 is a low temperature direct replacement for lithium floride (LiF), the material typically used by OLED display manufactures as the electron injector layer within an OLED display
OLED-T has developed E746 for OLED displays in the mobile market such as mobile phones and digital cameras where its power consumption and lifetime performance benefits are expected to deliver improved product performance.
In fluorescent red and fluorescent green customer OLED display devices, OLED-T's E746 material outperforms Alq3 in terms of energy efficiency, colour co-ordinates, lifetimes and voltage drift.
E746 enables OLED displays to be manufactured with a current efficiency increase of between 30% and 50%, a power efficiency improvement of as much as 45 to 80% and a lifetime increase of 100% for fluorescent red and 200% for fluorescent green.
'OLED-T is well positioned to take advantage of the growing market of OLED displays through its portfolio on materials for OLED displays'.
'E746 offers superior performance as a host material in OLED displays compared with existing OLED materials and crucially can be used as a direct replacement for aluminium quinolate meaning display manufacturers can gain the benefits using existing manufacturing processes', says Myrddin Jones, CEO, OLED-T.
The new E746 material is manufacturing process compatible with Alq3.
It has a lower toxicity than Aluminium based materials and is thermally stable up to 350C.
Available in kilogram quantities for customer testing, E746 is provided in a powder form that can be deposited onto a substrate by vacuum evaporation coating methods.
OLED-T is currently developing a variant of E746 for blue OLED displays.
