Dupont announced that they have achieved record performance from printed OLED TV display materials.

“DuPont announced that it has achieved record performance in printed organic light emitting diode OLED displays, sufficient to enable future adoption of OLED television (TV).  Using proprietary DuPont Gen 3 solution OLED materials, DuPont has demonstrated for the first time a solution-based manufacturing process in which OLEDs can be printed cost effectively while delivering the necessary performance and lifetime.”

The high cost and complexity of manufacturing OLED TV panels has been the main factor in the slow introduction of OLED TV technology. Dupont has apparently found a way to conquer both of these stumbling blocks.

“OLED displays in portable devices are available in the market today, but the current high-cost of manufacturing with evaporated materials has limited market adoption and constrained OLED manufacturing for larger size displays,” said David Miller, president – DuPont Electronics & Communications. “Now, with DuPont printed OLED materials and process technology, fabrication costs can be significantly reduced, and manufacturing can be scaled to accommodate TV-size displays.”

Dupont has developed new OLED materials that promise to drastically extend the life of future OLED TVs.

Great advances have been made especially in blue emitting materials;

“In addition, DuPont Displays developed some blue light-emitting materials. Among them, one with color coordinates of (0.14, 0.12) has a current efficiency of 6.0cd/A and a luminance half-life of 38,000 hours when measured with the initial luminance of 1,000cd/m2, according to the company.”

For deeper blues, “If the initial luminance is set at 200cd/m2, which is required for a display, the luminance half-life is calculated to be approximately 41,000 hours,” DuPont Displays said.”

This is far ahead of the current OLED TV material longevity specifically the short blue half-life of the Sony XEL-1 OLED TV.

Dupont and Dainippon have announced a partnership to develop a new OLED manufacturing process.

“The companies also have signed an agreement relating to their intention to bring together the elements needed – materials, technology and equipment – to mass produce OLED displays, delivering higher performance at a lower cost.

“The flat panel display market is about US$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 B Miller, group vice president of DuPont Electronic & Communication Technologies.

The companies are developing integrated coating and printing equipment for the fabrication of OLED displays from solution, an approach which 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.”

This is good news and helps to balance out the bad news on the Sony XEL-1 lifetime issues.
