Wherein, described display panel also comprises: for load the public electrode of common electric voltage in the demonstration stage.Above-mentioned touch-control drive electrode 11 can arrange with layer in mode insulated from each other with this public electrode, for example, by common pattern of electrodes, touch-control drive electrode 11 is distributed in the gap of described public electrode, there is preparation simple, can reduce the advantage of plate thickness and raising transmitance.
In addition, the second comparatively preferred embodiment in, described public electrode can also unite two into one with touch-control drive electrode 11, public electrode also serves as touch-control drive electrode simultaneously.Particularly, the common electrode layer of whole connection in tft array substrate in prior art is cut apart, formed multiple regions of mutually insulated, concrete each region can be strip electrode, this strip electrode loads common electric voltage in the demonstration stage, serves as public electrode; This strip electrode loads timesharing at touch detection-phase and loads first, second touch driving voltage, serves as touch drive electrode, as shown in 11 in Fig. 4.Public electrode shares with touching drive electrode, can avoid the impact of public electrode in the time of the touch control detection stage, reduces signal to noise ratio (S/N ratio).
It should be noted that, it shown in Fig. 4, is only a kind of specific implementation that meets the display panel of the two-sided touch-control of the present embodiment, only for ease of understanding, and be not used in restriction, first substrate can be array base palte or color membrane substrates in addition, and second substrate can be color membrane substrates or array base palte, in the time that first substrate is color membrane substrates, second substrate is array base palte, otherwise also can.For those skilled in the art better understand the structure of the display panel of the two-sided touch-control that the embodiment of the present invention provides, below taking first substrate in Fig. 4 as color membrane substrates, second substrate is that array base palte is that example more describes in detail the present invention.
Display panel as shown in Figure 4 comprises first substrate 14 (being color membrane substrates) and the second substrate 18 (being array base palte) to box mutually, be arranged on the color film 15 on first substrate 14, (in figure, the first touch-control sensing electrode 12 is arranged on the back side of first substrate, the i.e. outside of first substrate to be arranged on the first touch-control sensing electrode 12 on first substrate 14; Certain the first touch-control sensing electrode 12 also can be arranged on the another side of first substrate, the i.e. inner side of first substrate); Be arranged on the TFT layer 17 on second substrate 18, be arranged on second substrate 18 and away from first substrate to the second touch-control sensing electrode 13 of box face, (the second touch-control sensing electrode 13 is arranged on the outside of second substrate, in like manner also can be arranged on the inner side of second substrate), and common electrode layer.Common electrode layer comprises some strip electrodes (being 11 in Fig. 4), and public electrode shares this strip electrode with touch drive electrode.Between color membrane substrates and array base palte, be perfused with liquid crystal 16.
Figure 5 shows that the sequential chart of realizing driving method of the present invention, within the time of a frame, first carry out display scanning, then carry out touch signal scanning.Be divided into the first touch-control the sweep time of touch signal and drive period and the second touch-control to drive period two parts, in the time that the first touch-control drives the touch signal scanning of period, positive (i.e. the first sensitive surface) touch-control works; Scan when the first touch-control drives the touch signal of period, then started to carry out the touch signal scanning of the second touch-control driving period, now worked for reverse side (i.e. the second sensitive surface) touch-control.
In order to improve the existence of data line on tft array substrate or the noise that other factors produce, in the time carrying out touch-control scanning, first carry out one or many Noise scan, get rid of the impact of noise, complete Noise scan and carry out again the scanning of touch signal afterwards.In the present embodiment, adopt burst signal to carry out Noise scan, in the time of a whole frame, display, burst signal, touch signal carry out timesharing driving, carry out unlike signal scanning within the different time, have avoided crosstalking and affecting before unlike signal.
