Further, showing the time period, the touch-control sensing electrode unit is applied common electrode signal, can realize in the following way: to the data signal line timesharing apply GTG signal and common electrode signal, and when data signal line loaded common electrode signal, the signal switch unit by conducting outputed to the touch-control sensing electrode with the common electrode signal that data signal line loads.
The embedded touch-screen of above-mentioned condenser type that the utility model embodiment provides, owing to use the data signal line time-sharing multiplex, read the voltage signal that signal wire receives the coupling of touch-control sensing electrode as touch-control, realize touch controllable function, can be on existing array base palte preparation technology's basis, do not need to increase extra technology and promptly can be made into touch-screen, saved production cost, improved production efficiency.And, use data signal line to read signal wire as touch-control, can avoid increasing the IC that independent control touch-control reads signal wire, promptly adopt the IC of existing control data signal line can realize touch controllable function, can save cost of manufacture.
Particularly, the above-mentioned capacitive touch screen that the utility model embodiment provides is that the common electrode layer of whole connection in the array base palte is cut apart, form the touch-control sensing electrode and the touch-control drive electrode of mutually insulated, in the specific implementation, utilize each touch-control sensing electrode that common electrode layer forms generally in the array base palte column direction of pixel cell extend, each touch-control drive electrode generally in the array base palte line direction of pixel cell extend; Perhaps, utilize each touch-control sensing electrode that common electrode layer forms generally in the array base palte line direction of pixel cell extend, each touch-control drive electrode generally in the array base palte column direction of pixel cell extend; Certainly, the bearing of trend of touch-control sensing electrode and touch-control drive electrode can not done qualification at this along other directions yet.
Column direction with each touch-control sensing electrode pixel cell in the array base palte extends below, and each touch-control drive electrode line direction of pixel cell in the array base palte extends to example and describes.
Particularly, touch-control drive electrode of arranging in common electrode layer and touch-control sensing electrode can be rhombus electrode (as shown in Figure 1), slotting electrode (as shown in Figure 2) or the strip shaped electric poles (as shown in Figure 3) of referring to.Insert and refer to that electrode is meant that a touch-control drive electrode side relative with the touch-control sensing electrode has the dressing structure that is crisscross arranged respectively.Wherein, column direction wiring at the array base palte of the touch-control sensing electrode Rx shown in Fig. 1 to Fig. 3 in the figure, the line direction direction wiring of the array base palte of touch-control drive electrode Tx in the figure, because touch-control sensing electrode Rx and touch-control drive electrode Tx are arranging with layer, each bar induction drive electrode is divided into a plurality of touch-control sensing sub-electrodes of mutually insulated, for example: in the rhombus electrode as shown in Figure 1, form a touch-control sensing electrode Rx by 6 touch-control sensing sub-electrodes, in the strip shaped electric poles as shown in Figure 3, form a touch-control sensing electrode Rx by 2 touch-control sensing sub-electrodes.Also each bar touch-control drive electrode can be divided into a plurality of touch-control sensing sub-electrodes of mutually insulated, for example: form a touch-control drive electrode Tx by 4 touch-control driven element electrodes in the slotting finger electrode as shown in Figure 2, be Tx3a among Fig. 2, Tx3b, Tx3c and Tx3d form Tx3.
In the specific implementation, as shown in Figure 3, many touch-control drive signal lines 01 between the adjacent pixel unit in tft array substrate can be set in array base palte, each touch-control drive electrode Tx and at least one touch-control drive signal line 01 are electrical connected, for example shown in Figure 3, be electrical connected by a plurality of via holes.Acting as of touch-control drive signal line 01: the demonstration time period in a frame, import common electrode signal by touch-control drive signal line 01 to connected touch-control drive electrode Tx, in the touch-control time period, import touch scanning signals by touch-control drive signal line 01 to connected touch-control drive electrode Tx, generally speaking, can be simultaneously to each touch-control drive signal line 01 load signal.
