Filed: 2002-04-19
Abstract: PROBLEM TO BE SOLVED: To improve the driving method of bias compensation for a TFT type liquid crystal display and to suppress the flickering of the TFT-LCD to the minimum. SOLUTION: In a positive field interval, gate lines are driven by adding a first low level gate voltage. A first waveform is added to the first low level gate voltage. A liquid crystal display voltage is completely recharged at the starting point of the positive field interval. At the ending point of the positive field interval, a portion of the voltage is discharged to provide first voltage vibration amplitudes. During a negative field interval, the gate lines are driven by adding a second low level gate voltage. A second waveform is imparted to the second low level gate voltage. The liquid crystal display voltage is completely recharged at the starting point of the negative field interval. A portion of the voltage is discharged at the ending point of the negative field interval to provide second voltage vibration amplitudes.  Then, the first and the second waveforms are adjusted so that the root-mean-square-root of the liquid crystal display voltages in the positive field interval is approximately made equal to the root-mean-square-root of the voltages in the negative field interval.
