Patent ID: 7696970

Claim:
A driving circuit for inversion-driving a display panel having a plurality of data lines that supply a gray-scale voltage, the driving circuit comprising: a changeover switch for sequentially switching between a first operation of applying a positive gray-scale voltage to a first data line group and applying a negative gray-scale voltage to a second data line group and a second operation of applying a negative gray-scale voltage to the first data line group and applying a positive gray-scale voltage to the second data line group; a plurality of short-circuit switches for short-circuiting data line of the first data line group and data line of the second data line group to produce a plurality of short-circuited data line groups in a switching period between the first operation and the second operation; and a plurality of common node-connected switches corresponding to the plurality of data line groups and short-circuiting a corresponding one of the data line groups to a common node.
