Advances in Solution Printing and Processible Materials Used in AMOLED Display Manufacturing
John S. Richard, President, DuPont Displays
DuPont Organic Light Emitting Diode (OLED) solution process technology and materials represent the next-generation in achieving higher performance and lower cost flat panel displays and energy efficient lighting solutions. The promise of OLED technology has been to deliver displays that are more visually compelling and power-efficient than Liquid Crystal Displays (LCDs) at a lower manufacturing cost. Today, most of this promise has been realized in small-format displays, but manufacturing cost and product price premiums persist and even become more pronounced as production on glass size comparable to that used for large-format LCD production is considered.
Three key roadblocks must be removed for the successful mass production of OLED televisions. First, device performance in an actual display produced using manufacturing processes and architectures must achieve competitive thresholds for lifetime, efficiency, and color. Second, the processes and equipment required to accomplish this must be compatible with OLED production on 8G (2.5×2.8m) glass enabling competitive capital and fixed cost productivity. Third, thin-film organic deposition and patterning techniques must significantly reduce the waste of expensive OLED materials. DuPont has developed an industry leading competency in solution based deposition and patterning and OLED materials tailored to cost effectively produce future large format OLED displays with many of the fundamental and novel approaches developed by DuPont removing the barriers restricting mass adoption.
In this presentation the advantages and challenges associated with solution processing OLED devices and the strong interconnection with OLED materials on device performance and cost will be addressed.
