<p>In a liquid crystal display apparatus, while the complication of a driver circuit, etc., and an increase in operating frequency are suppressed, impulse display is implemented and the charge characteristics of pixel capacitances are improved. In an active matrix-type liquid crystal display apparatus, during a precharge period Tpr provided for each horizontal period, a precharge voltage VprP or VprN of the same polarity as that of a data signal S(i) provided during an effective scanning period immediately after the precharge period Tpr is provided to a source line. In each frame period, during a precharge period Tpr which is after the lapse of a predetermined period Tdp from the start of application of a pixel data write pulse Pw to a gate line, and during which a precharge voltage of the same polarity as that of the data signal S(i) provided during a period of a next pixel data write pulse Pw is provided to the source line, a black voltage application pulse Pb is applied to the gate line. Accordingly, along with black insertion for implementing impulse display, pixel capacitances are precharged.</p> |
