Abstract

Apparatus and methods for providing displays based upon the principle of photoluminescent quenching are described. The invention includes a method of displaying information using photoluminescence quenching, the method comprising providing an optoelectronic display comprising a photoluminescent material between a pair of electrodes, providing illumination for the photoluminescent material to cause the photoluminescent material to photoluminescence, and biasing the electrodes to at least partially quench the photoluminescence.
