Filed: 1973-11-21
Abstract: 1457536 Matrix displays and circuits therefor SHARP KK 21 Nov 1973 [22 Nov 1972] 54090/73 Heading G5C A plurality of multi segment liquid crystal display devices D1 ... Dm are sequentially and cyclically energized to display a multi digit number; a h.f. erase signal being applied to each device for a short period when the device selection pulse T10, T20 ... Tmo moves from one device to the next. Data is recirculated through a register X and supplied one digit at a time to a buffer store XB. During a digit display period, the common electrode A1 of the selected device D1 is energized by the signal T10 from a timing counter TC, the binary information in store XB is decoded at SD and applied to the appropriate segments K1 ... Kn of the devices. The signals applied both to the common electrodes A and segments K are reversed in polarity midway through each display period by gating circuits TL and Gp 1 , Gp 2  under the control of pulses # 1 , # 2 . The arrangement is such that the potential applied to the common electrode and segments are 180 degrees out of phase when the segments are to be displayed and in phase when the segments are not to be displayed. At the end of each digit display period when the device selection signal e.g. T10 returns to zero, a pulse α 2  opens a gate CG1. The circulating information in register X causes the contents of buffer XB to change at high frequency so that a high frequency erase signal is applied to the segments K. Pulses α 1  coincident with pulses α 2  are applied to circuits TL and prevent the issue of the next device selection signal T20 during the buffer updating and erasing period. This method of operation prevents the display of meaningless symbols.
