Abstract :
A totally electronic analog watch has been built, using a multiplexed liquid-crystal display and an I2L integrated circuit chip which includes a voltage regulator with temperature compensation for the display drive. With ½ duty cycle multiplexing, two timekeeping parameters, e.g., hours and minutes, can be displayed simultaneously.
