Below the touch-control drive electrode arranged in tft array substrate in above-mentioned touch screen is described in detail.
Usually, the precision of touch screen is generally at grade, the density of touch-control drive electrode and touch-control sensing electrode and width can being selected to ensure required touch accuracy according to required touch accuracy, the width control system of usual touch-control drive electrode and touch-control sensing electrode is preferred at 5-7mm.And the precision of liquid crystal display is generally at micron order, therefore, as shown in Figure 2, in the touch screen that the embodiment of the present invention provides, a general touch-control drive electrode Tx can be made up of adjacent a plurality of gate line G, and, each touch-control drive electrode generally can comprise the gate line of identical bar number, every touch-control drive electrode Tx1 and Tx2 is made up of i root gate line G in fig. 2, in the touch-control time period, each bar gate line of one touch-control drive electrode of composition can load identical touch scanning signals, use as a touch-control drive electrode, to ensure required touch accuracy.
