Abstract
The present invention provides a TFT array substrate, in comparison with the TFT array substrate utilizing 2D1G technology according to prior art, the amount of the scan lines is increased to diminish the amount of the data lines. The data lines are categorized into main data lines (MD) and sub data lines (SD), and the main data lines (MD) control main areas of the sub pixels at their two sides, and the sub data lines (SD) control sub areas of the sub pixels at their two sides. Meanwhile, two GOA drive circuit respectively positioned at left, right two sides of the display area perform dual side drive to all the scan lines. Accordingly, the color shift issue of VA type liquid crystal display can be improved, and the charge efficiency can be ensured to decrease the cost of the liquid crystal panel.
