Abstract
A method for electrically addressing fluorescent display element based on polymers and/or low molecular-weight organic materials using a fluorescent quenching effect due to an electric field. The method includes changing positive voltages applied to bright pixels in inverse relation to ambient light intensity, and changing negative voltages applied to dark pixels in direct relation to the ambient light intensity. An organic light-emitting diode display (OLED) mode and a field quenching photoluminescence emission device (FQPED) mode are employed according to the ambient light intensity of the display element.
