DuPont and Dainippon Screen Manufacturing Co. Ltd. are forming a strategic alliance to develop integrated manufacturing equipment for printed organic LED (OLED) displays. The companies also signed an agreement relating to their intention to bring together the elements—materials, technology, and equipment—needed to mass produce OLED displays.
DuPont brings to the alliance its distinctive small molecule-based OLED solution materials and proprietary process technology, which has achieved excellent performance in testing. For its part, 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 jointly develop nozzle printers as an efficient method for printing OLED displays from solution. The first production scale printer is currently being constructed.
“We were interested in extending our deep LCD equipment experience into the OLED marketplace and we felt that DuPont had developed a much needed, viable approach to OLED materials and technology that could expedite the commercialization of cost-effective OLED manufacturing,” said Yoshinari Yaoi, corporate senior executive officer and president, FPD Equipment Co., Dainippon Screen. “We believe that this alliance could be the key for manufacturers to be able to produce affordable, high-quality larger-size OLEDs using our unique nozzle printer technology.”
