Patent ID: 8044909

Claim:
A liquid-crystal display apparatus comprising: a liquid-crystal display device driven by an AC voltage; an image divider configured to temporally divide input image data into N (N≧2) for each frame; a correction unit configured to correct a driving voltage for driving said liquid-crystal display device based on a difference between adjacent divided image data obtained by the N division; a polarity inverter configured to invert a polarity to make drive polarities of adjacent divided image data different, out of the divided image data obtained by the N division including the divided image data for which driving voltage is corrected by said correction unit; a driver configured to drive said liquid-crystal display device using the polarity-inverted divided image data; an inversion order alteration unit which alters an inversion order for the drive polarities; at least two input units configured to input the image data; an input switch configured to switch between said at least two input units to input the image data from either input unit; and an input switching acceptance unit configured to accept a switching instruction to said input switch, wherein when image data of a plurality of programs broadcasted using a plurality of channels is input from either of said at least two input units, said input switching acceptance unit further accepts a broadcast program switching instruction, and wherein when said input switching acceptance unit accepts the broadcast program switching instruction, said inversion order alteration unit alters the inversion order.
