Cooling of Organic Light-Emitting Diode Display Panels with Heat Pipes

摘要

Organic light-emitting diode half life is a function of temperature and it decreases with increase in operating temperature. Hence thermal management is important for the efficient operation of OLED based displays. High luminance applications like aerospace cockpits require high power densities which lead to increase in their operating temperatures. Passive cooling is the preferred choice in aerospace applications. In this work passive cooling option with heat pipes is studied and implemented to reduce the display temperature rise.
