ABSTRACT:
A liquid crystal panel is driven with small number of kinds of voltage. First and second common voltages V0, V4 are generated symmetrically above and under the central common voltage V2 in the common voltage source. First and second segment voltages V1, V3 are generated symmetrically above and under the central common voltage V2 in the segment voltage source. Adjustment of contrast may be facilitated by adjusting common voltages and segment voltages independently or each other. Power may be realized by equalizing the segment voltages and the central common voltage when there is no display.
