POLARITY-REVERSAL DRIVING METHOD AND POLARITY-REVERSAL DRIVING CIRCUIT

摘要

A polarity-reversal driving method comprises: when a picture is displayed, sequentially connecting pixel units corresponding to a first gate line by using a first gate line, loading first data voltage signals to the connected pixel units by using odd-numbered columns of data lines, and loading second data voltage signals to the connected pixel units by using even-numbered columns of data lines, polarities of the first data voltage signals being opposite to those of the second data voltage signals; and sequentially connecting pixel units corresponding to a second gate line by using a second gate line, loading third data voltage signals to the connected pixel units by using odd-numbered columns of data lines, and loading fourth data voltage signals to the connected pixel units by using even-numbered columns of data lines, polarities of the third data voltage signals being opposite to those of the fourth data voltage signals. The polarity-reversal driving method reduces the number of times of the polarity reversal, thereby reducing the power consumption of a display panel. Also disclosed is a polarity-reversal driving circuit.
