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.
