Abstract

PURPOSE:To obtain graceful clock display by displaying clock performance, realizing luminescent state in half-tone besides luminescence and nonlighting. CONSTITUTION:Half-tone display is obtained when all the segments are lighted up by about 2% in duty with half-tone data, except the segment corresponding to a ''second'' indicator 36. At this time, second data is at zero level, and the ''shadow'' of the ''second'' indicator 36 is brought into closed-up. The contrast between the half- tone part 38 and the hour and minute indicators 32 and 34 can be discriminated distinctly in 1/15, and the distinction fron the ''second'' indicator 36 in nonlighting can be cleared up.
