Abstract
A driving system for a liquid crystal display apparatus and a method thereof are provided, the driving system comprises a data-latching circuit, a synchronous-signal separating module, a vertical synchronous-signal discriminator, a vertical synchronous-signal counter, a horizontal synchronous-signal discriminator, a data operator and a polarity-signal generator. The vertical synchronous-signal discriminator outputs a start signal to the polarity-signal generator when vertical synchronous signals exist. The vertical synchronous-signal counter accumulates an amount of the vertical synchronous signals, and outputs an accumulated result to the data operator. The horizontal synchronous-signal discriminator sends the start signal to the data operator. The data operator subtracts odd sub-pixel data from even sub-pixel data of RGB data in a horizontal line or subtracts the even sub-pixel date from the odd sub-pixel date to obtain an Msum value, and controls the polarity-signal generator output polar-controlling signals to scan lines according to the Msum value and the accumulated result.
