Abstract
A multi-alarm watch includes a liquid crystal display means for providing both conventional time displays and an alarm time schedule display indicating simultaneously a plurality of times of day scheduled for an alarm signal. Separated or overlapped displays are used. The displays are driven by AC multiplexed voltage signals with each display having a different duty cycle. A random access memory stores data for the scheduled alarm circuitry and display. For greater visibility the scheduled display shows alarm times for twelve hours at one time and an address decoder converts timekeeping signals into a memory address code for the alarm schedule. A conventional alarm is also provided, and distinctive audible signals identify different functional outputs.
