Abstract

PURPOSE: To reduce the number of elements in the driving circuit and to make it a integrated circuit easily by maintaining analog voltage in the capacitor and driving the liquid crystal display body of matrix configuration.
CONSTITUTION: The control voltage is applied to the gate of transistors Tr1∼Trn, and they are made to conduct in order within 1 scanning line time T2∼T3. The electric charge which is in proportion to the video signal is stored in order in the capacitors C1∼Cn in accordance with conduction of Tr1∼Trn, and the video signal is memorized. When the scanning line operation has been completed, in case Tr1∼ Trn are made to conduct by synchronizing with the horizontal synchronizing signal, and the driving voltage for the scanning line is applied to the line electrodes 501∼ 50n, the capacitors C1'∼Cn' maintain the driving voltage even if Tr1'∼Trn' become a breaking state. Tr1∼Trn continue to conduct in order, store the next scanning line information in C1∼Cn, and C1'∼Cn' maintain the previous scanning line information during the aforesaid operation. Simultaneously, transistors TR, TR' which are connected to the electrode 501 are controlled so that the selective potential is given during T3∼T5.
