DuPont and Dainippon Screen Manufacturing Co. Ltd will be working together to develop integrated manufacturing equipment for printed OLED displays. The companies also have signed an agreement relating to their intention to bring together the elements neededmaterials, technology and equipmentto mass-produce OLED displays, delivering higher performance at a lower cost.

"The flat-panel display market is about $100 billion annually and growing. DuPont is applying its science to make possible more vivid displays that are lower cost than current LCD displays," said David Miller, group VP, DuPont electronic and communication technologies. "We are excited to combine our strengths with Dainippon Screen's unique printing technology to bring to market the core technology that will enable improved high definition televisions and other flat-panel displays."

The companies are developing integrated coating and printing equipment for the fabrication of OLED displays from solution, an approach that is unique in the industry and can significantly reduce manufacturing costs for OLED displays. DuPont brings to the alliance its distinctive small molecule-based OLED solution materials and proprietary process technology from which excellent performance has been obtained in testing. Dainippon Screen has developed a unique printing technology, called nozzle printing, in which the OLED materials can be printed accurately at very high speed. The goal of the alliance is to develop integrated OLED printing and coating equipment that will significantly reduce the production costs of flat panel displays, with the aim of extending OLED technology to large size displays and making them cost-competitive with LCDs.

The companies have been working together over the past three years to co-develop nozzle printers as an efficient method for printing OLED displays from solution. The first production scale printer is currently being constructed.
