摘要:
A liquid crystal display apparatus includes a first group of pixel electrodes having a first parasitic capacitance, a second group of pixel electrodes having a second parasitic capacitance, a common electrode, liquid crystal interposed between the common electrode and the first and second groups of pixel electrodes, respectively, and a driver circuit determining a first common voltage in accordance with the first parasitic capacitance and supplying the first common voltage to the common electrode during a writing period of the first group of pixel electrodes so as to substantially offset a voltage drop in the second group of pixel electrodes due to the first parasitic capacitance, the driver circuit determining a second common voltage in accordance with the second parasitic capacitance and supplying the second common voltage to the common electrode during a writing period of the second group of pixel electrodes so as to substantially offset a voltage drop in the second group of pixel electrodes due to the second parasitic capacitance.
