Fig. 3 B be touch-control display panel 300 at different pictures during the cycle, the touch-control read signal voltage schematic diagram of each touch-control read line 306.Please refer to Fig. 3 A and Fig. 3 B, each touch-control read line 306 is between two adjacent data lines 304, each touch-control read line 306 for example is approximately D with left vertical apart from the shortest data line 304 distances, the shortest data line 304 distances of each touch-control read line 306 and right side vertical range for example are approximately D/3, in this embodiment, the distance of indication is two vertical range or bee-lines between circuit, is approximately distance that a specific range refers to display panel existing error in the patient scope of institute on making or measuring herein.Because distance between capacitor's capacity and two conductors is inversely proportional to, if therefore between each touch-control read line 306 and left data line 304, parasitic side direction capacitor's capacity is approximately Apf, the side direction capacitor's capacity between each touch-control read line 306 and right side data line 304 is approximately A*3pf.
The pattern that provides data voltage polarity in the R picture cycle due to many data lines 304 for "+-+-+-", so in the R picture cycle, left data line 304 is that negative polarity data voltage (can be 0V) and right side data line 304 are positive polarity data voltage (can be 15V).Because the capacitance coupling effect of side direction electric capacity, left data line 304 produces the negative sense coupled voltages to the touch-control read signal on each touch-control read line 306 to be changed, right side data line 304 produces the forward coupled voltages to the touch-control read signal on each touch-control read line 306 to be changed, so 304 pairs of touch-control read signal voltages of left data line 304 and right side data line produce after two side direction electric capacity (capacitance A pf and A*3pf) dividing potential drops the variation near 11.25V.In the present embodiment, touch-control read signal on each touch-control read line 306 all is subject to coupled voltages to be changed the distortion that causes and can't cancel each other, so cause the distortion of the touching signals on the touch induction lines 310 that is coupled to many touch-control read lines 306 even more serious, form the situation at Display panel image broken string as Fig. 2.
the pattern that provides data voltage polarity in the R+1 picture cycle due to many data lines 304 is "+-+-+", so in the R+1 picture cycle, left data line 304 is that positive polarity data voltage and right side data line 304 are the negative polarity data voltage, because the capacitance coupling effect of side direction electric capacity, left data line 304 produces the forward coupled voltages to the touch-control read signal on each touch-control read line 306 to be changed, right side data line 304 produces the negative sense coupled voltages to the touch-control read signal on each touch-control read line 306 to be changed, so the 304 pairs of touch-control read signal voltages of left data line 304 and right side data line produce after two side direction capacitance partial pressures the variation near 3.75V.In sum, a plurality of sensing cells 308 are coupled to many corresponding touch-control read lines 306, many touch-control read lines 306 are coupled to touch induction lines 310 and are coupled to processor 314 again, this connected mode can be strengthened the intensity of signal, and can make processor 314 can decide by a plurality of sensing cells 308 degree of touch-control, but the couple variations that when upgrading due to pixel 302, stray capacitance causes still can cause the distortion of the touching signals on touch induction lines 110.
Fig. 4 is the schematic diagram of delegation in another embodiment of the present invention touch-control display panel picture element matrix.As shown in Figure 4, touch-control display panel 400 comprises: a plurality of pixels 402, many data line 404(40402 ~ 40452), many touch-control read line 406(40602 ~ 40608), a plurality of sensing cell 408, touch induction lines 410, gate line 412 and processor 414.Each pixel 402 comprises a plurality of sub-pixels 4022, and each sub-pixel 4022 is coupled to the corresponding opposite data line 404 of two data polarity of voltages.Each sub-pixel 4022 can further comprise main block of pixels and time block of pixels.A plurality of sensing cells 408 are coupled to many corresponding touch-control read lines 406, many touch-control read lines 406 are coupled to touch induction lines 410 and are coupled to processor 414 again, wherein a kind of advantage of this connected mode is to strengthen the intensity of signal, and sensing cell 408 can be the touch control unit of light sense touch control unit (for example sensing cell 308) or other kind.The inner member of sensing cell 408 and operating principle are identical with the sensing cell 308 of above-mentioned Fig. 3 C, and the inner member of processor 414 and operating principle are identical with the processor 314 of above-mentioned Fig. 3 D, repeat no more.
In the present embodiment, 4 touch-control read lines 40602 ~ 40608 are couple to touch induction lines 410, but the invention is not restricted to this, and all 2N(N are positive integer) bar touch-control read line 406 is couple to touch induction lines 410 and all belongs to scope of the present invention.Touch induction lines 410 is coupled to processor 414.Gate line 412 is coupled to a plurality of sub-pixels 4022, gate line 412 can also further be coupled to a plurality of sensing cells 408 in addition, being used to provides signal in each picture cycle, when the signal activation, a plurality of sensing cells 408 can provide other touch-control read signal to corresponding touch-control read line 406 in many, touch induction lines 410 can be according to a plurality of touch-control read signal output touching signals to processor 414, and processor 414 can be according to the degree of touching signals judgement user touch-control.And the pixel 402 that can driving grid line 412 when the signal activation couples is upgraded.
