In addition, in Fig. 1, express the driving circuit section of LCD panel 1 simultaneously.Gate drivers (gate driver) the 10th, according to set scanning sequency, send each gate line g1, g2 ..., the sweep signal on the gn.When a certain grid is online when being loaded with sweep signal, can make samely to list or be conducting state with the thin film transistor (TFT) in online all display units of one scan.When a certain sweep trace was selected, data driver 20 was according to image data to be shown, via data line d11, d12 ... dm2 sends corresponding data-signal to m display unit of these row.After gate drivers 10 is finished once the online scanning motion of all n column scans, i.e. the display action of single frame (frame) is finished in expression.Therefore, each sweep trace of multiple scanning and send data-signal just can reach the purpose of continuous show image.
