OSRAM photoelectric development of lighting with white organic EL panel is not illuminated when the state is transparent

[Nikkei BP news] OSRAM semiconductor (OSRAM Opto Semiconductors GmbH) developed a successful white light organic EL panel for general lighting. The size of the panel is 90cm2, and the chromaticity of white light is in the CIE chromaticity diagram (0.396, 0.404). When the brightness is 1000cd/m2, the luminous efficiency is 20lm/W. Life of 20 thousand hours (before the brightness half-life).

The development of the white organic EL panel is not transparent when the state does not shine. Light transmittance is not currently 55%, but is expected to improve to improve by up to 75%.

Specific production date has not been determined. However, the scheduled delivery of samples within 2 years".
