Abstract: The invention provides an enhanced structure of a time display device includes a circle with 60 display units on the circumference of the clock face, among which 12 display units are made larger for displaying hour of time (hour display units) and the rest (smaller ones) displaying minute of time (minute display units). The display units are made with materials that shine or flicker to indicate time in the dark. To indicate hour of time, a given hour display unit and the two minute display units right next to this hour display unit would be switched on. To indicate minute of time, one of the minute display units would be switched on. While a given display unit has to indicate hour and minute at the same time, it flickers.
