ABSTRACT:
An active matrix liquid crystal drive circuit comprising an input-signal storage capacitor for storing an analog input signal, a differential amplifier which alternately presents a first operative state in which the output thereof is returned to the inverting input terminal thereof in a negative feedback manner and a second operative state in which the output is returned to the non-inverting input terminal thereof through a polarity inverting output buffer circuit in a negative feedback manner, and an output-voltage storage capacitor for storing an output voltage of the differential amplifier. In the first operative state, the voltage stored in the input-signal storage capacitor is applied to the non-inverting input terminal, and the output voltage which is returned to the inverting input terminal in a negative feedback manner is stored in the hold capacitor. In the second operative state, the voltage of the output-voltage storage capacitor is applied to the inverting input terminal and the output of the buffer circuit is output as a liquid crystal drive voltage.
