Abstract

PURPOSE:To reduce an energy consumption by flickering a light emitting diode in accordance with a clock pulse. CONSTITUTION:A power source input displaying circuit is composed of a transistor 1, resistances 2, 3, a light emitting diode 4, a clock pulse generating circuit 5 and a power source Vcc. The cathode of the light emitting diode 4 is connected to the collector of the transistor 1 through the resistance 3 and an output pulse 6 of the clock pulse generating circuit 5 is supplied through the resistance 2 to the base of the transistor 1. Thus, only when the output pulse 6 of the clock pulse generating circuit 5 is a high level, the transistor 1 is turned on and the light emitting diode 4 lights up.
