Picture image display device and method of driving the same |
摘要 |
By changing circuit connections at predetermined 4 timings, a switch feed through offset cancel circuit which permits canceling fluctuation in output offset of an analog picture image signal voltage due to fluctuation of semiconductor elements characteristics in the circuit. Thereby, a uneven brightness in a form of vertical stripe shape, which deteriorates picture quality, due to fluctuation in switch feed through charges of an offset cancel circuit is eliminated in a TFT LC display device having a buffer amplifier. <IMAGE> |
