ABSTRACT:
A method for driving a liquid crystal (LCD) display apparatus. The LCD display apparatus includes a liquid crystal panel arranged by a plurality of pixel units formed in a matrix shape, and a signal drive circuit for generating a liquid crystal apply voltage and constructed of at least two integrated circuits. A DC common electrode voltage is applied to one electrode of liquid crystal of the pixel units within the liquid crystal panel, and an AC voltage is applied to the liquid crystal to be driven.
