Abstract
A fluorescent printer head capable of being subject to dynamic driving to reduce the number of ICs required. A shield electrode is provided between anode arrays having anode dots arranged in an offset manner and control electrodes are respectively arranged for the anode arrays. The anode arrays are subject to dynamic driving and selected by the control electrodes. Such construction of the fluorescent printer head ensures smooth selection of the anode arrays during the dynamic driving. Also, it eliminates non-uniformity in luminance of the anode dots of the anode arrays and accomplishes downsizing of the printer head and a reduction in manufacturing cost thereof due to a reduction in the number of ICs required.
