Abstract: This invention discloses a type of radial circuit for use in driving LCD monitors. The radial circuit includes an odd-even column data generator. The odd-even column data generator receives data from a modulation counter and divides the data into two groups of data having opposite levels: odd column modulation data and even column modulation data. The odd-even column data generator then sends said two groups of data to a displayed data and modulation data comparing circuit in the LCD in order to control the odd and even columns of the LCD. The present invention divides all the columns in the same row into odd and even columns. Opposite driver voltage waveform is output from between the odd and even columns of the neighboring columns. While the odd column discharges, the even column charges. This type of simultaneous discharge and charge process creates just the right mutual electric charge compensation; and it results in minimizing the electric charge dissipation which saves energy.
