Abstract

PURPOSE: To eliminate inconvenience for users and to make easy to see for the display, by performing the second display with the filcker of light emitting substance and the position of illumination.
CONSTITUTION: The pulse to, 0.5 second On and 0.5 second OFF, is formed from the reference frequency oscillator 1 with the frequency divider DIY2, the light emitting element LE is driven via DRIV1 and flickering every one second is made. On the other band, the pulse to is further divded for the frequency, the frequency divided wave of each digit of the frequency divider DIV4 and opposite phase wave are fed to the selection timing pulse generating circuit STPG to form the 12 sets of selection timing pulses t1 to t12 sequentially shifted in the pulse width in 5 seconds. Since this pulse controls the sequence of light emission of the element LE on the time display plate, each element LE shifts the position of light emission while repeating the flicker in 5 seconds. Generally, 5 × n seconds flicker per one second can be made. Thus, the bewilderness at second display can be avoided and the display is made easy to see.
