Patent ID: 7592992

Claim:
An inversion method for use in a liquid crystal display comprising pluralities of pixels, comprising: dividing the plurality of pixels by columns into a plurality of groups comprising first groups and second groups; providing a first inversion signal and a second inversion signal to respectively determine polarities of first group pixels and second group pixels, wherein the first and second inversion signals are different non-periodic signals, and each of the first inversion signal and the second signal is a non-periodic signal with an individually random alternative of a first level and a second level; generating first data voltages for the first group pixels according to the first inversion signal and data signals corresponding to each of the first group pixels; generating second data voltages for the second group pixels according to the second inversion signal and data signals corresponding to each of the second group pixels; and providing a scan signal to scan the pixels, such that the first data voltages and second data voltages are converted to illuminate corresponding pixels.
