Abstract

PURPOSE:To eliminate the irregular coloring between respective dispaly digits and provide a uniform and stable dispaly by erasing all the display elements of an ECD element after time correction. CONSTITUTION:When a second reseting switch S1 is operated after the time is corrected by operating switches S2, S3, a refresh circuit 25 is operated by the reset instruction signal Rc based on the operation of the switch S1. Then, all the display elements of an ECD element 30 are erased for a fixed time after the time correction. In this way, the irregular coloring densities between the respective display digits after the time correction are performed and the uniform and stable display is obtained by providing a means of erasing all the display elements for a certain time, for example, about 10sec, after the time correction. It is also possible to detect the completion of the time correction and to generate a reset instruction automatically in place of operating the second resetting switch S1.
