High Efficiency, High Brightness, and Long-Lasting Cavity Organic Light-emitting Diode
This paper describes a new generation of organic light emitting diode (OLED), the cavity organic light emitting diode ( COLED). A typical COLED consists of a top electrode (anode) and a bottom electrode (cathode) separated by a thin dielectric layer. The top electrode and the dielectric layer are etched to form a number of small holes, or cavities, which are filled with organic light emitting materials such as a light-emitting polymer (LEP). When a voltage is applied across the top and bottom electrodes, photons are generated within the LEP molecules along the cavity perimeter. In comparison to a traditional OLED, a COLED device can operate at approximately two orders of magnitude higher current density with potentially up to five times higher efficiency. Therefore, it is suitable for applications that require high efficiency and high brightness, such as backlighting for LCD displays, large panel passive matrix OLED displays, and general lighting applications.
