ABSTRACT:
A liquid crystal driver IC drives a liquid crystal display apparatus by supplying the potential of one reference power source or the potentials of two reference power sources selected from among a plural number of reference power sources on the basis of the displayed data to the liquid crystal display apparatus by time sharing. The supply line of the reference power source for an intermediate value among the plurality of reference power sources is divided into at least two supply lines and the fixed directions of current flowing through the respective divided lines are maintained. The voltage-drop and voltage build-up of the reference power sources resulting from the electric charge flowing into and out of the reference power sources are limited to one of each of the two supply lines. The resulting voltage fluctuations of the reference power source are low, making it possible to supply the liquid crystal display apparatus with stable voltage required for the improvement of display definition.
