All printed OLED device uniquely combines the characteristics of an emissive display such as OLED,
including good brightness and switching speed in the range of milliseconds,
with a plastic substrate and an " all printed" manufacturing process.
These displays are now ready for a range of applications in a variety of consumer products.
A number of development activities have taken place to allow this technical progress;
the critical ones are listed below:
Improved contrast displays.
This has resulted in a simplified manufacturing process whilst achieving very good contrast ratios.
Reduction of the maximum voltage required to turn the devices on within ~1 sec from 40V to 24V.
This has been achieved though improvement in materials and device optimisation.
Development of gravure printing process
Storage lifetime tests demonstrate these devices have at least a 2 year shelf-life
