Japan Sony and Blu ray OLED components display Idemitsu

Japanese manufacturers and Sony announced jointly develop Sanyo Electric blue emitting OLED element, and has confirmed the internal quantum efficiency is 28.5%, and the luminous life of 30 thousand hours or more.

The blue emitting OLED element is combined with the luminous materials Idemitsu organic semiconductor materials and components developed by SONY "Super Top Emission" structure and components. The color purity of the luminous color is in accordance with the CIE chromaticity coordinate value (0.137,0.065). The blue light emitted is deeper than the NTSC standard value (0.14, 0.08).

In the aspect of the luminous life (brightness half life), the results of the continuous illumination test at the initial brightness of 200cd/m2 and the temperature of 50 DEG C, the results show that the actual time is more than 30 thousand hours. Unit current brightness of 3.9cd/A. From this result, it is expected to reduce the red (R), green (G), blue (B) color OLED components in the largest power consumption of the blue OLED component, and is expected to achieve OLED TV, large.

In the case of fluorescent materials, the luminous efficiency is the highest in the world. The results will be released in the United States, Losangeles, the International Conference on display technology Display (SID2008 for (Society Information)) released.
