Abstract:
1. A driving system for a liquid crystal display (LCD) apparatus, comprising a data-latching circuit, a synchronous-signal separating module and a polarity-signal generator, the data-latching circuit being configured for separating input signals into RGB data and data-enable signals, the synchronous-signal separating module being configured for converting the data-enable signals into vertical synchronous signals and horizontal synchronous signals, wherein the driving system for the LCD apparatus further comprises a vertical synchronous-signal discriminator, a vertical synchronous-signal counter, a horizontal synchronous-signal discriminator and a data operator; the vertical synchronous-signal discriminator, the vertical synchronous-signal counter and the horizontal synchronous-signal discriminator are electrically coupled to the synchronous-signal separating module; the vertical synchronous-signal discriminator sends out a start signal to the polarity-signal generator if it judges there are the vertical synchronous signals; the vertical synchronous-signal counter is configured for accumulating an amount of the vertical synchronous signals and sending out an accumulated result to the data operator; the horizontal synchronous-signal discriminator sends out a start signal to the data operator if it judges there are the horizontal synchronous signals; and the data operator starts to operate after receiving the start signal sent out from the horizontal synchronous-signal discriminator, subtracts data of odd sub-pixels by data of even sub-pixels which are arranged in a horizontal line of the RGB data or subtracts data of the even sub-pixels by the odd sub-pixels, to obtain an Msum value, and then controls the polarity-signal generator to output polar-controlling signals corresponding to a scan line according to the Msum value and the accumulated result of the vertical synchronous-signal counter accumulating the amount of the vertical synchronous signals.
