Abstract:
A drive circuit for liquid-crystal displays which applies a voltage to display cells in a liquid-crystal display, comprising:a driving buffer for outputting a drive voltage to be applied to a display cell;a holding capacitor; anda switching circuit for switching a first state, in which a first input voltage is applied to an input terminal of said driving buffer, a first terminal of said holding capacitor is connected to an output terminal of said driving buffer, and a second terminal of said holding capacitor is connected to a terminal at which a first given voltage exists, and a second state in which a second input voltage is applied to said first terminal of said holding capacitor, said input terminal of said driving buffer is connected to said second terminal of said holding capacitor, and a drive voltage is applied to said display cell through said output terminal of said driving buffer.
