Abstract

PURPOSE:To discriminate different sets of information with a small number of display segments and make display possible by differing the luminescent colors of the display segments constituted by electroluminescence. CONSTITUTION:Electroluminescence contg. >=two kinds of luminescent center additives of different frequency depencencies of luminescence intensities, for example, ZnS:Cu, Pb, Clor ZnS:Cu, Mn change in luminescent colors from green to blue and from yellow to green respectively as driving frequencies are higher. A plurality of the display segments constituted by such electroluminescence are provided, and the driving frequencies to the display segments are changed in correspondence to the current time and plural times such as an alarm time, the time of other cities, stopwatch and the like, whereby the two times are displayed simultaneously with different colors.
