Selected Problems Related to the Durability of Organic Structures (OLED)

Zbigniew Porada


Abstract: Organic light emitting diodes (OLED) are surface light sources, wherein the thickness of the active layer - polymer - is generally not greater than 500 nm. The rapid development of OLED technology dates back to 2000 years. In 2002, the first Active Matrix OLED panels, and in 2007. It demonstrated a prototype TV made in OLED technology. The most important disadvantage of the displays produced by the OLED technology is that the stability of such organic materials is not very high. OLED emitting structures covered by an aging processes that depend on a number of factors and cause a systematic decrease in the luminance of the emitted light. The paper proposes a mathematical model describing the process of aging in OLED structures, which satisfactorily describes the aging of such structures and allows the calculation of time, after which the luminance of the emitted light reaches 50 % of its initial value (contractual service life).
