Abstract

PURPOSE:To display bar graphs at a high-duty cycle without deteriorating the brightness and contrast, by driving all display elements in several groups of display blocks forming a display body and some of display elements separately in two intervals. CONSTITUTION:Bar-graph display body 20 consists of display blocks 20-1, 20- 2 composed of ten display elements. Display elements in respective blocks 20-1, 20-2 are connected to the common electrodes driven by driver circuits 31, 32 , and corresponding display elements in each block are connected in common to driver circuits 41, 42 . Therefore, circits 31, 32 selected corresponding to data, and all display elements of blocks 20-1, to be displayed by circuits 41 to 50 are driven in the 1st interval by the control output of control circuit 100 synchronizing with the clock of clock generator 11, and some display elements in repective blocks 20-1 selected by circits 41 , and respectively-selected circuits 31 are driven in the 2nd interval, so that the bar-graph display of high quality will be attained.
