Hodogaya promotes its transport materials for the Novaled PIN OLED(tm) structures

Date Announced: 19 Nov 2008

Tokyo, Japan; Dresden, Germany.

Hodogaya Chemical Co., LTD, long experienced specialist and market leader in charge transport materials, and Novaled AG, leader in power efficient and long living Organic Light Emitting Diodes (OLEDs) have agreed to offer hole transport materials for Novaled PIN OLED™ structures.

Hodogaya has exclusively developed specific Hole Transport Material for Novaled fitting very well with the Novaled PIN OLEDTM structures. As a first result Novaled is enhancing its material offer with an additional hole transport material called NHT18.

The new NHT18 has a similar behavior in OLEDs like NPB, but provides additional advantages to OLED manufacturers. For example, the Tg of NHT18 is above 130°C and thus gives a high temperature stability in OLED devices. The current efficiency in today’s fluorescent blue emitting PIN OLEDs is 10% higher.

"The OLED industry is looking for energy saving. The Novaled PIN technology is a very recognized approach for power efficient OLED devices," says Dr. Toshio Obara, Managing Executive Officer, OLED Materials Division of Hodogaya. "We are very pleased to cooperate with Novaled through its high quality transport material."

"Novaled strategy is to associate key material makers to its PIN offer for the benefit of our customers," says Gerd Guenther, VP Marketing & Sales of Novaled. "We are very pleased to add Hodogaya, recognized for the high performance of its transport material, to our partnerships and pushing the PIN structure as a standard in the OLED field."

About OLEDs
OLEDs (organic light-emitting diode) are semiconductors made of thin organic material layers of only a few nanometers thickness. They emit light in a diffuse way to form an area light source. In a fast growing display market OLEDs are key part of a revolution: the dream of paper-thin, highly efficient displays with brilliant colors and great flexibility in design is becoming reality. OLEDs represent the future of a vast array of completely new lighting applications. By combining color with shape, organic LEDs will create a new way of decorating and personalizing people’s surroundings with light. At the same time OLEDs offer the potential to become even more efficient than energy-saving bulbs.
