Abstract
PURPOSE:To display time in colors by applying no voltage to the segments selected to display the minute and the time, and applying the voltage above the threshold value to other nonselected segments. CONSTITUTION:Display segments corresponding to the hands are arranged radially in 60 rows X2 columns, and the hour is displayed by segments 0-59 and the minute by segments 0'-59' respectively. In the rear surface, 10 groups of segment blocks B1-B10 are constituted by 10 groups of segments by 6 pieces of zigzag segment electrodes X1-X6 and in the front surface, block electrodes of a sector shape are disposed in two columns, wherein the block electrodes Y1 and Y11 correspond to the block B1 and the block electrodes Y10 and Y20 to the block B10, respectively. When a signal S1 is applied to the electrodes 0-59 and Y1-Y10 displaying the hour, a signal S2 to the electrodes 0'-59' displaying the minute, a signal S3 to the nonselected electrodes 0-59 and 0'-59' and a signal S4 to the nonselected electrodes Y1-Y20 respectively, the time is displayed in colors.
