Abstract
A driving method with reducing image sticking effect is disclosed. The driving method includes applying a voltage on the data lines for trapping impurities crossing the data lines and lowering the degree of the image sticking effect, and applying different asymmetric waveforms to different data lines for trapping impurities crossing the data lines and lowering the degree of the image sticking effect.

A driving method for reducing image sticking associated with images of a liquid crystal display, the liquid crystal display comprising a plurality of data lines, a plurality of scan lines and a plurality of pixel areas, the driving method comprising:
- during a first period of time, sequentially turning on the plurality of scan lines and inputting data of a first image to the plurality of pixel areas;
- during a second period of time, sequentially turning on the plurality of scan lines and inputting data of a second image to the plurality of pixel areas;
- and
- between the first period of time and the second period of time, generating and applying a first voltage having a voltage level higher than a highest voltage level corresponding to the data of the first image.
