Liquid crystal display panel and display driving method

A display driving method, suitable for driving a liquid crystal display panel, the liquid crystal display panel comprising a plurality of data lines on a plurality of columns, a plurality of scan lines on a plurality of rows, a plurality of common electrode lines and a plurality of pixel units on the rows, each of the rows having a plural of pixel units, each of the pixel units being electrically coupled to a corresponding data line and a corresponding scan line, the pixel units on the same row being electrically coupled to the same scan line, each of the pixel units comprising a storage capacitor, the capacitors of the pixel units on each row being electrically coupled one corresponding common electrode line, the driving method comprising:

• before a data-writing period to the pixel units on the (N−K−1)th row, setting a voltage level on the common electrode line of the N-th pixel units opposite to a voltage level on the common electrode line of the (N−1)th pixel units, wherein N is a positive integer larger than 1;
• during the data-writing period to the pixel units on the (N−K−1)th row, setting the voltage level on the common electrode line of the N-th pixel units in the same polarity as the voltage level on the common electrode line of the (N−1)th pixel units;
• and
• after the data-writing period to the pixel units on the (N−K−1)th row, setting the voltage level on the common electrode line of the N-th pixel units opposite to the voltage level on the common electrode line of the (N−1)th pixel units, wherein K is zero or a positive integer less than (N−2).
