Development and Mass-Production of OLED Lighting Panels with High Luminance, Long Lifetime and High Efficiency
2014
OLED (organic light-emitting diode) lighting is expected to be new generation electric power saving solid state lighting friendly to human beings and the environment, and has attained a long lifetime superior to fluorescent lamps. Despite being in need of further improvement of luminous efficacy, it is expected to become a light source that has features including thinness, light weight, and eye-friendliness due to surface light emission, allowing for new lighting space design to fulfill various needs.This paper describes its present development progress, issues and future direction, focusing on efficiency improvement, and reports on the development of an OLED lighting panel with high luminous efficacy (40 lm/W) and a long lifetime (40,000 hours) that has attained a sufficient variety of products.
