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.
Claims5
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:
- at a first period of time, turning on the plurality of data lines;
- at the first period of time, sequentially turning on the plurality of the scan lines;
- at the first period of time, inputting data of a first image to the plurality of the pixel areas to display;
- at a second period of time, turning on the plurality of data lines;
- at the second period of time, sequentially turning on the plurality of the scan lines;
- at the second period of time, inputting data of a second image to the plurality of the pixel areas to display;
- between the first period of time and the second period of time, turning off the plurality of scan lines;
- and
- between the first period of time and the second period of time, applying a first voltage to a first set of the plurality of the data lines.
