It should be noted that, in the technical program, the first touch control electrode layer 10 is arranged on first substrate or second substrate, the second touch control electrode layer 20 is arranged on first substrate or second substrate, refers to that the first touch control electrode layer 10 and the second touch control electrode layer 20 can be arranged on same substrate also can be arranged on different substrate. In the time of specific design, can select according to actual needs. In addition, the touch-control display panel that the technical program provides can be organic LED display panel, can be also display panels. In the time that touch-control display panel is display panels, first substrate or second substrate are specifically as follows array base palte or the color membrane substrates in display panels. In the time that touch-control display panel is organic LED panel, first substrate or second substrate are specifically as follows array base palte or the cover plate in organic LED panel.
Wherein, the first touch-control electrode 11 can be regular pattern or irregular pattern, and the second touch-control electrode 21 can be regular pattern or irregular pattern. Here refer to, each the first touch-control electrode 11 and each second touch-control electrode 21 can be regular pattern, also can irregular pattern. The pattern of each first touch-control electrode 11 can be identical with the pattern of other the first touch-control electrodes 11 or the second touch-control electrode 21, also can be not identical with the pattern of other the first touch-control electrodes 11 or the second touch-control electrode 21. Similarly, the pattern of each the second touch-control electrode 21 can be identical with the pattern of other the second touch-control electrodes 21 or the first touch-control electrode 11, also can be not identical with the pattern of other the second touch-control electrodes 21 or the first touch-control electrode 11. In Fig. 2 a, Fig. 2 b and Fig. 2 c, exemplarily provide the structural representation of three kinds of touch-control display panels. In Fig. 2 a, in the first touch control electrode layer 10, the pattern of the first touch-control electrode 11 is regular rectangle pattern, but in the second electrode lay 20, the pattern of the second touch-control electrode 21 is irregular pattern. In Fig. 2 b, in the first electrode layer 10, the pattern of the first touch-control electrode 11 is irregular pattern, but in the second touch control electrode layer 20, the pattern of the second touch-control electrode 21 is regular rectangle pattern.

In the time of specific design, can be according to demand, determine the pattern of the first touch-control electrode 11 and the second touch-control electrode 21.
Consider if N the first touch-control electrode 11 all inputted after touch control detection signal, if the distance (the first spacing) between two adjacent the first touch-control electrodes 21 is too little, can there is each other phase mutual interference; Similarly, if M the second touch-control electrode 21 all inputted after touch control detection signal, if the distance (the second spacing) between two adjacent the second touch-control electrodes 21 is too little, also can there is each other phase mutual interference, this determines impact the accuracy of position of touch. Preferably, the ratio of the first touch-control electrode 11 first spacing on first direction 111 at the first width of first direction 111 and adjacent two the first touch-control electrodes 11 is less than 5:1, and the ratio of the second touch-control electrode 21 second spacing in second direction 211 at the second width of second direction 211 and adjacent two the second touch-control electrodes 21 is less than 5:1.
Further, according to electrostatic screen principle, the touch-control electrode that is positioned at upper strata may will be positioned at the signal shielding of touch-control electrode of lower floor, preferably, if the second touch control electrode layer 20 is positioned at the first touch control electrode layer 10 tops, the width of the second touch-control electrode 21 in second direction 211 is less than the width of the first touch-control electrode 11 on first direction 111. Arrange like this and can effectively weaken the electrostatic screen effect of the second touch control electrode layer 20 to the first touch control electrode layer 10. It should be noted that, suppose that the second touch control electrode layer 20 is positioned at the first touch control electrode layer 10 tops here, this is only a concrete example, but not limitation of the present invention. In the time of specific design, the second touch control electrode layer 20 can be set and be positioned at the first touch control electrode layer 10 tops, the first touch control electrode layer 10 also can be set and be positioned at the second touch control electrode layer 20 tops. Further, preferably, first direction and second direction angle are 90 degree.

In the time of specific design, if the shape of each touch-control electrode or material difference, the direct-to-ground capacitance value of each touch-control electrode own is also different, and makes each touch-control electrode needle to same touch action, and the touch control detection change amount signal of output varies. In this case, though can calculate position of touch information according to the touch control detection change amount signal of each touch-control electrode output, its computational process is numerous and diverse, determines that position of touch is consuming time long, and user experiences not good. For the touch control detection change amount signal that effectively reduction is exported according to touch-control electrode is determined the needed time of position of touch, preferably, the direct-to-ground capacitance of each the first touch-control electrode is the first capacitor C 1, and/or the direct-to-ground capacitance of each the second touch-control electrode is the second capacitor C 2. Design like this, can effectively simplify the process of determining position of touch according to the touch control detection change amount signal of touch-control electrode output, is conducive to improve user and experiences. Further alternative, the first capacitor C 1 is identical with the value of the second capacitor C 2.
In addition, also it should be noted that, if utilizing the resolution ratio of existing techniques in realizing touch-control display panel is 64, touch area need to be divided into 64 touch-control electrode blocks, and each touch-control electrode block is all electrically connected with driving a signal input output interface on chip by a connection wire. The resolution ratio that even will realize touch-control display panel is 64, needs altogether 64 to connect wire and 64 signal input output interfaces. And utilize technical scheme provided by the present invention, only need 8 the first touch-control electrodes that extend along first direction and 8 the second touch-control electrodes that extend along second direction just can make the resolution ratio of touch-control display panel reach 64. Accordingly, in this case, need altogether 16 to connect wire and 16 signal input output interfaces.

Fig. 6 is the flow chart of a kind of touch control detecting method of providing of the embodiment of the present invention. This touch control detecting method comprises:
S610 in the touch-control time period, drives chip to send touch control detection signal to N the first touch-control electrode and M the second touch-control electrode simultaneously.
S620, the touch control detection change amount signal of N the first touch-control electrode and described M the second touch-control electrode described in described driving chip detection, and determine position of touch according to the touch control detection change amount signal of described N the first touch-control electrode and described M the second touch-control electrode.
Fig. 7 a-Fig. 7 d is the schematic diagram of determining position of touch according to the touch control detection change amount signal of N the first touch-control electrode and M the second touch-control electrode. Below in conjunction with Fig. 7 a-Fig. 7 d to determining that according to the touch control detection change amount signal of N the first touch-control electrode and M the second touch-control electrode the concrete methods of realizing of position of touch is elaborated.
Before describing definite method of position of touch in detail, the direct-to-ground capacitance of supposing each described the first touch-control electrode is the first capacitor C 1, the direct-to-ground capacitance of each described the second touch-control electrode is the second capacitor C 2, and relative electric capacity between any one first touch-control electrode and any one the second touch-control electrode is C3.
Within the touch-control time period, in the time of finger touch touch-control display panel, can cause finger touch position is that near the first touch-control electrode of position of touch and the second touch-control electrode, touch control detection signal changes. According to the difference of user's touch manner, four kinds of situations below main existence:
Situation one, if a first touch-control electrode detection to the first touch control detection change amount signal, and the second touch control detection change amount signal detected on a second touch-control electrode, the crosspoint of a described first touch-control electrode and a second touch-control electrode is position of touch. Exemplarily, as shown in Figure 7a, in the time that user only touches A position, the touch control detection signal of the first touch-control electrode 11-2 corresponding with A position and second these two electrodes of touch-control electrode 21-2 all can change. For the first touch-control electrode 11-2, the change amount signal Δ V (C1) that its touch control detection change amount signal (i.e. the first touch control detection change amount signal) is caused by C1 while being mainly derived from touch-control and the change amount signal Δ V (C3) being caused by C3. Therefore, the first touch control detection change amount signal is Δ V1=Δ V (C1)+Δ V (C3). For the second touch-control electrode 21-2, the change amount signal Δ V (C2) that its touch control detection change amount signal (i.e. the second touch control detection change amount signal) is caused by C2 while being mainly derived from touch-control and the change amount signal Δ V (C3) being caused by C3. Therefore, the second touch control detection change amount signal is Δ V2=Δ V (C2)+Δ V (C3).
Situation two, if at first touch-control electrode detection to the three touch control detection change amount signals, and on two the second touch-control electrodes, the second touch control detection change amount signal detected, two crosspoints of a described first touch-control electrode and two the second touch-control electrodes are position of touch. Exemplarily, as shown in Figure 7b, in the time that user touches B position and C position simultaneously, first touch-control electrode 11-2, the second touch-control electrode 21-2 corresponding with B position and C position and the touch control detection signal of second these three electrodes of touch-control electrode 21-3 all can change. For the first touch-control electrode 11-2, there are two positions to be touched, the change amount signal 2 Δ V (C1) that its touch control detection change amount signal (i.e. the 3rd touch control detection change amount signal) is caused by C1 while being mainly derived from touch-control and the change amount signal 2 Δ V (C3) that caused by C3. Therefore, the 3rd touch control detection change amount signal is Δ V3=2 Δ V (C1)+2 Δ V (C3). For the second touch-control electrode 21-2 (or second touch-control electrode 21-3), the change amount signal Δ V (C2) that its touch control detection change amount signal (i.e. the second touch control detection change amount signal) is caused by C2 while being mainly derived from touch-control and the change amount signal Δ V (C3) being caused by C3. Therefore, the second touch control detection change amount signal is Δ V2=Δ V (C2)+Δ V (C3).
Situation three, if at second touch-control electrode detection to the four touch control detection change amount signals, and on two the first touch-control electrodes, the first touch control detection change amount signal detected, two crosspoints of a described second touch-control electrode and two the first touch-control electrodes are position of touch. Similarly, as shown in Figure 7 c, in the time that user touches D position and E position simultaneously, first touch-control electrode 11-2, the first touch-control electrode 11-3 corresponding with D position and E position and the touch control detection signal of second these three electrodes of touch-control electrode 21-2 all can change. Particularly, for the second touch-control electrode 21-2, there are two positions to be touched, the change amount signal 2 Δ V (C2) that its touch control detection change amount signal (i.e. the 4th touch control detection change amount signal) is caused by C2 while being mainly derived from touch-control and the change amount signal 2 Δ V (C3) that caused by C3. Therefore, the 4th touch control detection change amount signal is Δ V4=2 Δ V (C2)+2 Δ V (C3). For the first touch-control electrode 11-2 (or first touch-control electrode 11-3), the change amount signal Δ V (C1) that its touch control detection change amount signal (i.e. the first touch control detection change amount signal) is caused by C1 while being mainly derived from touch-control and the change amount signal Δ V (C3) being caused by C3. Therefore, the first touch control detection change amount signal is Δ V1=Δ V (C1)+Δ V (C3).
Situation four, if two the first touch-control electrode detection to the first touch control detection change amount signal, and the second touch control detection change amount signal detected on two the second touch-control electrodes.
For example, as shown in Fig. 7 d, in the time that user touches F position and G position simultaneously, the touch control detection signal of first touch-control electrode 11-2, first touch-control electrode 11-3, second touch-control electrode 21-2 and second touch-control electrode 21-4 this four electrodes corresponding with F position and G position all can change. Particularly, for the first touch-control electrode 11-2 (or first touch-control electrode 11-3), the change amount signal Δ V (C1) that its touch control detection change amount signal (i.e. the first touch control detection change amount signal) is caused by C1 while being mainly derived from touch-control and the change amount signal Δ V (C3) being caused by C3. Therefore, the first touch control detection change amount signal on the first touch-control electrode 11-2 (or first touch-control electrode 11-3) is Δ V1=Δ V (C1)+Δ V (C3). For the second touch-control electrode 21-2 (or second touch-control electrode 21-4), the change amount signal Δ V (C2) that its touch control detection change amount signal (i.e. the second touch control detection change amount signal) is caused by C2 while being mainly derived from touch-control and the change amount signal Δ V (C3) being caused by C3. Therefore, the second touch control detection change amount signal on the second touch-control electrode 21-2 (or second touch-control electrode 21-4) is Δ V2=Δ V (C2)+Δ V (C3). Like this due to the equal and opposite in direction of the touching signals variable quantity on the first touch-control electrode 11-2 and the first touch-control electrode 11-3, the equal and opposite in direction of the touching signals variable quantity on the second touch-control electrode 21-2 and the second touch-control electrode 21-4, cannot determine that concrete position of touch is F position and G position or H position and I position. For this situation, demand motive chip sends the second touch control detection signal to two the first touch-control electrodes and two the second touch-control electrodes simultaneously, and determines position of touch according to the touching signals variable quantity of two the first touch-control electrodes and two the second touch-control electrodes.
