POLYCHROMATIC ORGANIC EL ELEMENT, ITS MANUFACTURING PROCESS, AND DISPLAY USING THIS ELEMENT Russian patent published in 2001 - IPC

FIELD: large-area low-voltage display elements. SUBSTANCE: polychromatic EL element has light-emitting layer including at least two organic dyes that may function as light-emitting centers (luminescent centers) wherein at least one of mentioned organic dyes is modified so as to change element-emitted light color. EL element manufacturing process includes full or partial irradiation of light-emitting layer for modifying at least one organic dye. RGB dot- matrix displays of passive- and active-matrix type are also proposed. EFFECT: enhanced effectiveness due to high light output and easy selection of component colors. 9 cl, 9 dwg
