DuPont Displays Inc announced that it developed new OLED materials designed for coating process.
Dupont are announcing that at the SID-2009 in San Antonio. This is Duponts third generation OLED material.
Among them, a green light-emitting material has a luminance half-life of more than one million hours when measured by setting the initial luminance at 1,000cd/m2, the company said. This is equivalent to 100 or more years of continuous emission. The green light-emitting material has color coordinates of (0.26, 0.65) and a current efficiency of 25cd/A.
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.
Dupont said that this is one of the longest life blue light emitting materials that have ever been announced.
“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.
