Progress with all Printed Flexible OLED Displays (OLEDs LIVE! USA 2013)

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

CDT has developed a portfolio of thin, flexible, organic, printed electronic devices including OLED displays, sensors, transistors, energy harvesters and more. CDT's solution processed, in-air-deposited active layers, air-stable cathodes and simple encapsulation process (lamination) provides new functionality, freedom of design and easy system integration in a broad range of applications.
