Abstract: An embodiment of the present invention provides a column inversion driving circuit. The column inversion driving circuit could reduce the voltage level of the logic low of the nth impulse signal, which is used to control the nth TFT matrix, through the cooperation of the voltage level of the nth impulse signal and the nth positive data signal. Furthermore, the voltage level of the logic high of the (n+1)th impulse signal, which is used to control the (n+1)th TFT matrix, is also reduced through the cooperation of the voltage level of the (n+1)th impulse signal and the (n+1)th negative data signal. This reduces the power consumption of the column inversion driving circuit.
