Embodiment
A specific embodiment according to the present invention is a touch induction installation.In practical application, this touch induction installation can be integrated in device for mobile communication, panel computer, PC or the interactive information display board isoelectronic series system, but is not limited with these situations.This touch induction installation comprises a touch-control sensing panel and P the first inductor, and definition has N row induction region on this touch-control sensing panel.Whether this P the first inductor be touched in order to detect this N row induction region.N is the integer greater than 3, and P is the positive integer less than N.
Fig. 2 (A) and Fig. 2 (B) illustrate N and equal 4 and the P example that equals 3.Definition has 4 row to be parallel to the induction region of directions X on the touch-control sensing panel 20, and the central authorities of each row induction region are provided with a line of induction (being represented by dotted lines) 22.Shown in Fig. 2 (A), the line of induction 22 of the 1st row induction region is coupled to the first inductor 24A, the line of induction 22 of the 2nd row induction region is coupled to the first inductor 24B, the line of induction 22 of the 3rd row induction region is coupled to the first inductor 24C, and the line of induction 22 of the 4th row induction region is to be coupled to the first inductor 24A equally.Easy speech, the 1st row induction region and the 4th row induction region share same the first inductor.
Shown in Fig. 2 (B), the central series of these induction regions is equal to the spacing of each line of induction 22 apart from d1.Minimal-contact diameter when these row are designed to touch these induction regions less than the user apart from d1 makes all contacts bump doing the induction region to I haven't seen you for ages touching two row direct neighbors by this.For example, if the thickness of user's finger thickness or pointer nib then is listed as apart from d1 and can be designed to equal 5mm to I haven't seen you for ages greater than 6mm.In this example, the contact point A of containing simultaneously the 1st row, the 2nd row induction region can make the output signal of the first inductor 24A and 24B change.Similarly, contain simultaneously the 3rd row, the 4th row induction region contact point B the output signal of the first inductor 24C and 24A is changed.
Based on above design, add the 2nd row, corresponding the first inductor difference of the 3rd row induction region, even if the 1st row induction region and the 4th row induction region share the first inductor 24A, when the output signal of the first inductor 24A changed, the subsequent analysis circuit still can judge it is that the 1st row induction region or the 4th row induction region are touched.More particularly, visual what occur simultaneously that output signal changes with the first inductor 24A is that the first inductor 24B or the first inductor 24C judge that touched person is the 1st row induction region or the 4th row induction region to the subsequent analysis circuit.Change if output signal appears in the first inductor 24A and 24B approximately simultaneously, represent that touched person is the 1st row induction region.Relatively, change if output signal appears in the first inductor 24A and 24C approximately simultaneously, represent that touched person is the 4th row induction region.
Fig. 3 (A) and Fig. 3 (B) illustrate N and equal 7 and the P example that equals 5.In the example shown in Fig. 3 (A), the 1st row and the 4th row induction region share same the first inductor 24A, the 2nd row and the 6th row induction region share same the first inductor 24B, and its excess-three row induction region is then separately corresponding to the first inductor 24C, 24D, 24E.In the example shown in Fig. 3 (B), the 1st row and the 7th row induction region share same the first inductor 24A, the 3rd row and the 6th row induction region share same the first inductor 24C, and its excess-three row induction region is then separately corresponding to the first inductor 24B, 24D, 24E.As aforementioned, touch the Basic Design of the induction region of two row direct neighbors to I haven't seen you for ages based on all contact actions, in Fig. 3 (A), even if the 1st row and the 4th row induction region share same the first inductor 24A and the 2nd row and the 6th row induction region and share same the first inductor 24B, as long as the first inductor of output signal variation occurs approximately simultaneously and the first inductor that output signal changes occurs approximately simultaneously with the first inductor 24B by distinguishing with the first inductor 24A, can judge real touched induction region.Similarly, in Fig. 3 (B), the first inductor of output signal variation occurs approximately simultaneously and the first inductor that output signal changes occurs approximately simultaneously with the first inductor 24C by distinguishing with the first inductor 24A, also can judge real touched induction region.Fig. 3 (A) and Fig. 3 (B) are in order to expression, and in the situation that the numerical value of N and P is fixed, the wire laying mode of spirit according to the invention may be not only a kind of.
Can be found out by above several examples, if arrange n1 row and n2 row induction region in the N row induction region to share same the first inductor (n1 and n2 are respectively the positive integer less than or equal to N), as long as order separately corresponding the first inductor of other row induction regions with these n1 row and n2 row induction region direct neighbor is neither identical, the subsequent analysis circuit can effectively be got rid of the generation of terrible point (ghost), that is get rid of the situation of erroneous judgement and other induction region of shared same the first inductor of this touched induction region, be which row induction region and correctly differentiate touched.
It should be noted that above-mentioned wire laying mode can further expand to making the induction region more than two row share same the first inductor.Easy speech, the induction region that shares inductor is not classified limit as with two, needs only separately neither identical with corresponding first inductor of other row induction regions of the induction region direct neighbor of these shared inductors.In sum, touch induction installation according to the present invention makes the different lines of induction be shared same the first inductor, and then reduces the total quantity of the first inductor by suitable wiring configuration.
Fig. 4 illustrates the example that touch induction installation according to the present invention further comprises an analysis module.Analysis module 26 is touched by the user in order to judge which or which row induction region.As discussed previously, the output signal of the first inductor that shares when this n1 row and n2 row induction region shows that induction region is touched, then be this n1 be listed as or n2 row induction region one of them is touched; Analysis module 26 can further judge it is that these n1 row or n2 row induction region are touched according to the output signal of corresponding the first inductor of other direct neighbor row induction regions.For instance, if also touched with one of n1 row induction region direct neighbor row induction region, then analysis module 26 judges it is that n1 row induction region is touched.Relatively, if also touched with one of n2 row induction region direct neighbor row induction region, then analysis module 26 can judge it is that n2 row induction region is touched.
Fig. 5 (A) and Fig. 5 (B) illustrate the distribution plan example of the output signal of these the first inductors, and its longitudinal axis is signal intensity, and transverse axis is column number.In this example, what in fact the user touched is n1 row induction regions.Shown in Fig. 5 (A) and Fig. 5 (B), be that the signal intensity of n1 and n2 is equally all quite high corresponding to column number, but be that (n1+1) and signal intensity (n1-1) are (n2+1) and signal intensity (n2-1) apparently higher than column number corresponding to column number.Analysis module 26 judges it is n1 row but not n2 row induction region is touched according to such difference.
In another embodiment of the present invention, each the row induction region in the above-mentioned N row induction region is each self-contained M hurdle induction region again, and M is the integer greater than 1.And this touch induction installation further comprises to detect this M hurdle induction region, and whether Q touched the second inductor: Q is the positive integer less than or equal to M.So, a touch induction installation of the present invention can correctly detect and judge for some position touched on the induction panel.Should be noted that, if touch-control sensing panel 30 is self-capacitance formula (self-capacitive) induction panel, then this P the first inductor and this Q second inductor is all the reception inductor.If touch-control sensing panel 30 is a mutual capacitance type induction panel, then this P the first inductor is P reception inductor, and this Q the second inductor is Q and drives inductor.
Fig. 6 (A) illustrates that Q equals M and touch-control sensing panel 30 is the example of a self-capacitance formula induction panel.Shown in Fig. 6 (A), the M hurdle induction region in each row all is coupled to same the second inductor by a line of induction that is parallel to Y-direction.Q equals M and represents, each hurdle induction region is separately corresponding to second a different inductor.The output signal of the output signal of this M the second inductor and this P the first inductor is provided to analysis module 26 equally.Analysis module 26 can be judged touched planimetric position on touch-control sensing panel 30 according to the output signal of this P the first inductor and this M the second inductor.
Fig. 6 (B) illustrates Q and is the example of mutual capacitance type induction panel less than M and touch-control sensing panel 30.In this example, M is greater than 3, and this Q driving inductor is by a driver module 28 controls.In this example, aforementioned utilization suitably wiring also is applied to being parallel to the line of induction of Y-direction to reach the concept that shares inductor in this, so Q can be less than M.Easy speech, m1 hurdle and m2 hurdle induction region in this M hurdle induction region can share same the second inductor (m1 and m2 are respectively the positive integer less than or equal to M); As long as corresponding the second inductor of other hurdle induction regions with m1 hurdle and m2 hurdle induction region direct neighbor is neither identical separately in order, it is that analysis circuit 26 can effectively be differentiated touched for which hurdle induction region.Similarly, the center column of these induction regions makes all contact actions touch the induction region of two hurdle direct neighbors to I haven't seen you for ages apart from also being designed to less than aforementioned minimal-contact diameter by this.It should be noted that the induction region that is parallel to Y-direction and shared inductor, also be not limited with two hurdles.
In one embodiment of the invention, touch-control sensing panel 30 has roughly orthogonal and the first side and the second side that are uneven in length.Because it is complicated more many than the phase inverter (inverter) that drives in the inductor to receive the operational amplifier (operational amplifier) that adopts in the inductor, receive the hardware cost of inductor usually above driving inductor.Therefore, have identical induction and judge the touching mode with the driving inductor based on above-mentioned reception inductor, if the first side is shorter than the second side, then this P reception inductor can be arranged to corresponding to this first side, and this Q driving inductor is arranged to corresponding to this second side.By this, in the situation that can reach good inductive effects equally, the holistic cost of touch induction installation can be further reduced.
Also be a mutual capacitance type touch control induction installation according to another specific embodiment of the present invention.This touch induction installation comprises a touch-control sensing panel 40, P the first inductor 42 and Q the second inductor 44.Definition has N row, M hurdle induction region on the touch-control sensing panel 40, and N and M are respectively the integer greater than 1.Whether P the first inductor 42 be touched in order to detect this N row induction region, and P is the positive integer less than N.Q the second inductor 44 is in order to drive this M hurdle induction region, and Q is the integer greater than M.Below explanation will be take touch-control sensing panel 40 as a mutual capacitance type induction panel, this P the first inductor 42 is for receiving inductor, and this Q the second inductor 44 is example for the situation of driving inductor.
Fig. 7 illustrates N and equals 4 and the M example that equals 3.Touch induction installation in this example comprises 2 and receives inductors (42A, 42B) and 6 driving inductors (44A～44F).As shown in the figure, the 1st row and the 3rd row induction region share and receive inductor 42A, and the shared inductor 42B that receives of the 2nd row and the 4th row induction region.It should be noted that to be positioned at the corresponding driving inductor of induction region on same hurdle in the 1st row and the 3rd row induction region different.For example, the induction region that is positioned at the 1st row, the 1st hurdle is corresponding to driving inductor 44A, and the induction region that is positioned at the 3rd row, the 1st hurdle is corresponding to driving inductor 44D.
Change if receive the output signal of inductor 42A, what the subsequent analysis circuit sent the driving signal in the time of can occuring according to variation is which drives the planimetric position that inductor is judged touched point.Similarly, change if receive the output signal of inductor 42B, what the subsequent analysis circuit sent the driving signal in the time of also can occuring according to variation is which drives the planimetric position that inductor is judged touched point.
Can be found out by above example, if arrange n1 row in the N row induction region and shared same the first inductor of n2 row induction region (n1 and n2 are respectively the different positive integers less than or equal to N), be different from corresponding this second inductor of this induction region (m1 is the positive integer less than or equal to M) that is positioned at n2 row, m1 hurdle as long as order is positioned at corresponding this second inductor of this induction region on n1 row, m1 hurdle, it is that the subsequent analysis circuit can effectively be differentiated touched for which row induction region.As long as it should be noted that to meet above-mentioned design principle of disposal wires, the induction region that shares inductor is not classified limit as with two.In addition, in a driving inductor that shares show its corresponding induction region at least one when touched, can fully utilize the signal of other row induction region of the induction region institute direct neighbor of above-mentioned correspondence to the subsequent analysis circuit, and to send what drive signal when change occuring be which drives inductor, to judge the position of touched point.For example, arrange n1 row and n2 row induction region in the N row induction region to share same the first inductor, be same as corresponding this second inductor of this induction region that is positioned at n2 row, m1 hurdle if be positioned at corresponding this second inductor of this induction region on n1 row, m1 hurdle, but application of aforementioned n1 row and the n2 row difference of corresponding the first inductor of direct neighbor induction region respectively then judges which row induction region touched be.
Touch induction installation in above-described embodiment is the quantity that configures to reduce the first inductor by suitable wiring equally.If these first inductors are the reception inductor in the mutual capacitance type induction installation, above-mentioned configuration mode also can reach the effect that reduces holistic cost.In addition, if this touch-control sensing panel has two roughly orthogonal and not isometric sides, then this P reception inductor can be arranged to corresponding to shorter side, and this Q drives inductor and can be arranged to corresponding to long side.
As shown in Figure 8, aforementioned touch induction installation can further comprise an analysis module 46.The output signal of the first inductor (42A or 42B) that shares when n1 row and n2 row induction region shows that n1 row or n2 row induction region are touched, and analysis module 46 can (the output signal judgement of 44A～44F) be which induction region is touched according to these second inductors.
