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.

In order to complete a container, the anode substrate is spaced from the cathode substrate a predetermined distance apart and the fringe portions of the substrates are sealed. A supporting member is disposed in the container.

Abstract: The voltage to be applied to fixed display segments are made to be substantially the same to prevent irregular luminance distribution so as to improve display quality. In consideration of allowable voltage drop occurring attributable to the levels of electric currents which flow in electric lines of fixed display segments, the same voltage is applied to the fixed display segments by determining the resistance values by changing the pattern shapes (the lengths, the widths, the thicknesses and the line) of electric lines of the fixed display segments. If the fixed display segments have the same display area, the widths of the electric lines of the fixed display segments are determined to correspond to the ratios of lengths of electric lines of the fixed display segments in order to cause the fixed display segments to be applied with the same voltage.

Abstract: Field-emitted electrons are converged by a structure according to the present invention in which odd order gate lines are connected to a first gate lead electrode, while even order gate lines are connected to a second gate lead electrode. When the first gate lead electrode is selected and operated, the potential of the second gate lead electrode is made to be a low level. Since the odd order gate line is disposed between low level even order gate lines, emitted electrons can be converged. When the second gate lead electrode is selected and operated, a contrary process is performed so that emitted electrons are converged. Each gate line has three dot-like field emission arrays, which correspond to red, green and blue color components, so that color image apparatus is structured.
