Abstract
A driving circuit and driving method adapted for driving a data line of a display panel are provided. At least one predetermined table is provided by a controller circuit and applied according to a polarity state of a pixel data in related to a polarity state of its previous pixel data. A first or second mapping table is selected when the two polarity states are identical. A third or fourth mapping table is selected when the two polarity states are different. A corresponding pixel voltage based on the selected mapping table is generated for driving the data line, such that polarity transition between two adjacent sub-pixel units using common data line is considered. In addition, a method of establishing the at least one predetermined table is proposed as well. The invention achieves in providing better visual performances and suppressing conventional visual defects on a liquid crystal display panel.
