Patent ID: 7304641

Claim:
A timing generator of a flat panel display for generating a PAC (polarity arrangement control) signal and sending the same to a data driver so that the data driver is operative to control a polarity of display data based on the PAC signal and send the display data to a display panel, the timing generator comprising: a storage unit for storing plural sets of polarity data and plural PAC signals in advance wherein each said set of polarity data includes plural data polarities and each said set of polarity data corresponds to one of the PAC signals respectively; an operation unit for receiving the display data, each said set of polarity data, and a corresponding one of the PAC signals so that the operation unit is operative to perform an inner product operation with respect to the polarity data of each said set of polarity data and the display data for obtaining a sum of coupling voltages corresponding to the polarity data of each said set of polarity data; and a comparison unit if or comparing the sum of coupling voltages with a predetermined value, and outputting the corresponding PAC signal if the sum of coupling voltages is smaller than a pre-determined value, thereby generating a PAC signal with the sum of coupling voltages smaller than the pre-determined value.
