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.

Abstract: A reliable and efficient circuit for lighting a discharge lamp is described. An inverter accepts a direct current supply voltage and outputs an alternating current lamp voltage to drive the discharge lamp at a relatively high frequency. In one embodiment, the inverter includes semiconductor switches in a full-bridge configuration, a transformer feedback circuit to control the semiconductor switches, and a series L-C resonant circuit. In one embodiment, the inverter includes semiconductor switches in a half-bridge configuration, a transformer feedback circuit to control the semiconductor switches, and a series L-C resonant circuit. The inverter can drive multiple discharge lamps in a parallel configuration. A bypass circuit can also be coupled across a cathode of the discharge lamp to extend the life of the discharge lamp. The bypass circuit activates when a lamp cathode wears out.

Abstract: The present invention provides an image-display device using a phosphor which can improve a luminescence efficiency and characteristics of color coordinates by adding a IIA element to a host crystal of a ZnS phosphor to make a compound crystal. It is possible to provide an image-display device which can realize improvement in luminescence efficiency and color coordinate characteristics which has not been solved in the prior art, by using a phosphor expressed by Zn(1nullx)MIIAxS:MIB,MIII where MIIA is one or more ITA elements in an element periodic table; MIB is one or more IB elements; and MIII is one or more MITIA elements (Sc, Y) and MITIB elements (Al, Ga, In).
