Liquid electrochemiluminescent organic light emitting cell

Investigation of liquid phase organic electroluminescence is being of special interest as a competition of “liquid” and “solid” organic light emitted diodes (OLEDs). From the electrochemical point of view, electrogenerated chemiluminescence is a self-regenerating process providing high brightness light radiation due to recombination of oppositely charged dye radicals. Electrogenerated chemiluminescence displays have a competitive suit of parameters: high light efficasy, low power consumption, low driving voltages, fast response time, high spatial resolution, very high optical transmission and wide operating temperature range. No polarizes or alignment layers are required. Samples of electrogenerated chemilumine-scence displays, including matrix microdisplay and micromechanically made ECL cell are presented; its design and parameters are discussed in details.
