Abstract

The invention provides a scanning line driving method and device of display panel. The display panel comprises many scanning lines, data lines and pixel units defined by interlaced scanning lines and data lines. The scanning line driving method comprises the following steps: dividing adjoining many frames into the first frame group and the second frame group; opening the scanning lines corresponded to each frame in the first frame group by forward scan and opening the scanning lines corresponded to each frame in the second frame group by reverse scan. The crosstalk phenomenon from each frame in the first frame group and that from each frame in the first frame group cancels each other out, which improves crosstalk phenomenon and the display quality of the display panel.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a scanning line driving method and a scanning line driving device of a display panel. Background technique [0002] With the rapid development of thin film transistor liquid crystal displays (TFT-LCDs), people have higher and higher requirements on the display quality of products. However, crosstalk is a common adverse phenomenon of TFT-LCD. People define crosstalk as an abnormal display phenomenon in which the display of a certain area in the entire screen will be affected by another area, resulting in picture distortion. [0003] Crosstalk often needs to be seen in certain specific images, such as displaying the white area in the middle under a grayscale background. Due to the occurrence of crosstalk, the upper area of ​​the white area is brighter and the lower area is darker. And as multiple frames of images are displayed gradually, and each frame of images cau...
