Paper Abstract

Brief history, modern state and development trends of organic electroluminescent structures technology (so-called OLED technology) are reviewed including research activities in this field in Russia. It's noted that OLED technology is one of the most promising newly emerging display technologies. Due to advantages of these devices (low power consumption, potential flexibility, wide color range) it is particularly well suited for small area display applications (micro displays) such as cell phones, virtual imaging systems, portable electronics. Experimental results for homemade blue light emitting OLED structures and hermetically sealed numeric displays are presented including photoluminescence (PL) and electroluminescence (EL ) current-voltage and brightness characteristics. It is noted that visible electroluminescence is observed at ultra low current level of nearly 1 μA, luminous efficiency exceeding 1 lm/W thus being nearly the same as for super bright inorganic inGaN/IGaN LEDs. Special attention is paid for destabilizing factors (temperature and degradation phenomena) influence on device characteristics.
