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 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 on this touch-control sensing panel, definition has N row induction region.Whether this P the first inductor be touched in order to detect this N row induction region.N be greater than 3 integer, P is the positive integer being less than N.
Fig. 2 (A) and Fig. 2 (B) illustrates N and equals 4 and the P example that equals 3.On touch-control sensing panel 20, definition has 4 row to be parallel to the induction region of X-direction, and the central authorities of each row induction region are provided with a line of induction (being represented by dotted lines) 22.As 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 be coupled to the first inductor 24A equally.Easy speech it, the 1st row induction region and the 4th row induction region share same first inductor.
As 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.These row are designed to be less than minimal-contact diameter when user touches these induction regions apart from d1, make all contacts touch 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 the finger thickness of user or pointer nib is greater than 6mm to I haven't seen you for ages, then row can be designed to equal 5mm apart from d1.In this example, contain simultaneously the 1st row, the 2nd row induction region contact point A the output signal of the first inductor 24A and 24B can be made to 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 can be made to change.
Based on above design, add that the 2nd row, the first inductor corresponding to the 3rd row induction region are different, 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 changes, 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 to occur outputing signal what change with the first inductor 24A be 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 subsequent analysis circuit simultaneously.If output signal change appears in the first inductor 24A and 24B approximately simultaneously, represent that touched person is the 1st row induction region.Relatively, if output signal change 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) illustrates N and equals 7 and the P example that equals 5.In the example shown in Fig. 3 (A), 1st row and the 4th row induction region share same first inductor 24A, 2nd row and the 6th row induction region share same first inductor 24B, and its excess-three row induction region then corresponds to first inductor 24C, 24D, 24E separately.In the example shown in Fig. 3 (B), 1st row and the 7th row induction region share same first inductor 24A, 3rd row and the 6th row induction region share same first inductor 24C, and its excess-three row induction region then corresponds to first inductor 24B, 24D, 24E separately.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 first inductor 24A and the 2nd row and the 6th row induction region share same first inductor 24B, as long as by distinguishing the first inductor of occurring with the first inductor 24A outputing signal and changing and occur outputing signal the first inductor changed with the first inductor 24B approximately simultaneously approximately simultaneously, really touched induction region can be judged.Similarly, in Fig. 3 (B), by distinguishing the first inductor of occurring with the first inductor 24A outputing signal and changing and occur outputing signal the first inductor changed with the first inductor 24C approximately simultaneously approximately simultaneously, also really touched induction region can be judged.Fig. 3 (A) and Fig. 3 (B) is in order to represent, when the numerical value of N and P is fixing, the wire laying mode of spirit according to the invention may be not only a kind of.
Can be found out by above several example, if arrange the n-th 1 row in N row induction region and the n-th 2 row induction regions to share same first inductor (n1 and n2 is respectively the positive integer being less than or equal to N), as long as order separately with this n-th 1 arrange neither identical with the first inductor corresponding to other row induction regions of the n-th 2 row induction region direct neighbors, subsequent analysis circuit effectively can get rid of the generation of terrible point (ghost), that is get rid of the situation judged by accident and share other induction region of same first inductor with this touched induction region, and which row induction region correctly differentiates touched be.
It should be noted that above-mentioned wire laying mode can expand further to making the induction region arranged more than two share same first inductor.Easy speech it, the induction region sharing inductor not with two row for limit, as long as separately neither identical with the first inductor corresponding to other row induction regions of the induction region direct neighbor of these shared inductors.In sum, touch induction installation according to the present invention, by suitable wiring configuration, makes the different lines of induction be able to shared same first inductor, and then reduces the total quantity of the first inductor.
Fig. 4 illustrates the example that touch induction installation according to the present invention comprises an analysis module further.Analysis module 26 is in order to judge which or which row induction region is touched by user.As discussed previously, the output signal display induction region of the first inductor shared when these the n-th 1 row and the n-th 2 row induction regions is touched, be then this n-th 1 arrange or the n-th 2 row induction regions one of them is touched; Analysis module 26 output signal of the first inductor further corresponding to other direct neighbor row induction regions can judge it is that these the n-th 1 row or the n-th 2 row induction regions are touched.For example, if also touched with one of the n-th 1 row induction region direct neighbors row induction region, then analysis module 26 judges it is that the n-th 1 row induction regions are touched.Relatively, if also touched with one of the n-th 2 row induction region direct neighbors row induction region, then analysis module 26 can judge it is that the n-th 2 row induction regions are touched.
Fig. 5 (A) and Fig. 5 (B) illustrates 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 user touched is the n-th 1 row induction regions.As 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 to correspond to column number be the signal intensity of (n1+1) and (n1-1) is the signal intensity of (n2+1) and (n2-1) apparently higher than column number.Analysis module 26 judges to be the n-th 1 row according to such difference but not the n-th 2 row induction regions are touched.
In another embodiment of the present invention, each the row induction region in above-mentioned N row induction region is each self-contained M hurdle induction region again, M be greater than 1 integer.Further, this touch induction installation comprises to detect the whether touched Q of this M hurdle induction region the second inductor: Q is further the positive integer being less than or equal to M.So, a touch induction installation of the present invention correctly can detect and judge for some position touched on induction panel.Should be noted that, if touch-control sensing panel 30 is a self-capacitance (self-capacitive) induction panel, then this P the first inductor and this Q the second inductor are all 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 Q and equals M and touch-control sensing panel 30 is the example of a self-capacitance induction panel.As shown in Fig. 6 (A), the M hurdle induction region in each row is all coupled to same second inductor by the line of induction that is parallel to Y-direction.Q equals M and represents, each hurdle induction region corresponds to a second different inductor separately.The output signal of this M the second inductor is same with the output signal of this P the first inductor is provided to analysis module 26.Analysis module 26 can judge the touched planimetric position of point 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 less than M and touch-control sensing panel 30 is the example of mutual capacitance type induction panel.In this example, M is greater than 3, and this Q drives inductor to be controlled by a driver module 28.In this example, the concept that aforementioned utilization suitably connects up to reach shared inductor is also applied to being parallel to the line of induction of Y-direction in this, therefore Q can be less than M.Easy speech it, the m1 hurdle in this M hurdle induction region and m2 hurdle induction region can share same second inductor (m1 and m2 is respectively the positive integer being less than or equal to M); As long as order is separately neither identical with the second inductor corresponding to other hurdle induction regions of m1 hurdle and m2 hurdle induction region direct neighbor, it is that analysis circuit 26 can effectively be differentiated touched for which hurdle induction region.Similarly, the center column of these induction regions, apart from being also designed to be less than aforementioned minimal-contact diameter, makes all contact actions touch the induction region of two hurdle direct neighbors to I haven't seen you for ages by this.It should be noted that and be parallel to Y-direction and the induction region sharing inductor, be not also limited with two hurdles.
In one embodiment of the invention, touch-control sensing panel 30 has the first side and second side that roughly orthogonal and length do not wait.Complicated more many than the phase inverter (inverter) driven in inductor owing to receiving the operational amplifier (operational amplifier) adopted in inductor, receive the hardware cost of inductor usually above driving inductor.Therefore, with driving inductor based on above-mentioned reception inductor there is identical induction and judge touching mode, if first side is shorter than second side, then this P reception inductor can be arranged to corresponding to this first side, and drives inductor to be arranged to corresponding to this second side by this Q.By this, when reaching 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.On touch-control sensing panel 40, definition has N row, M hurdle induction region, and N and M is respectively the integer being 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 being less than N.Q the second inductor 44 is in order to drive this M hurdle induction region, and Q is the integer being greater than M.Below illustrate will be a mutual capacitance type induction panel with touch-control sensing panel 40, this P first inductor 42 for receiving inductor, and the situation that this Q the second inductor 44 be driving inductor is example.
Fig. 7 illustrates N and equals 4 and the M example that equals 3.Touch induction installation in this example comprises 2 and receives inductor (42A, 42B) and 6 drivings inductor (44A ~ 44F).As shown in the figure, the 1st arranges and the 3rd row induction region shared reception inductor 42A, and the 2nd row and the 4th row induction region share reception inductor 42B.It should be noted that the 1st row are different with the driving inductor corresponding to the induction region being positioned at same hurdle in the 3rd row induction region.For example, be positioned at the 1st row, the induction region on the 1st hurdle correspond to and drive inductor 44A, and be positioned at the 3rd row, the induction region on the 1st hurdle corresponds to and drives inductor 44D.
If the output signal receiving inductor 42A changes, what send drive singal when subsequent analysis circuit can occur according to change is which drives inductor to judge the planimetric position of touched point.Similarly, if the output signal receiving inductor 42B changes, what send drive singal when subsequent analysis circuit also can occur according to change is which drives inductor to judge the planimetric position of touched point.
Can be found out by above example, if arrange the n-th 1 row in N row induction region and the n-th 2 row induction regions to share same first inductor (n1 and n2 is respectively the different positive integers being less than or equal to N), as long as order is positioned at the n-th 1 row, this second inductor corresponding to this induction region on m1 hurdle is different from this second inductor (m1 is the positive integer being less than or equal to M) corresponding to this induction region being positioned at the n-th 2 row, m1 hurdle, it is that subsequent analysis circuit can effectively be differentiated touched for which row induction region.As long as it should be noted that and meet above-mentioned design principle of disposal wires, the induction region sharing inductor does not arrange as limit with two.In addition, in a driving inductor shared show induction region corresponding to it at least one touched time, the signal of other row induction region of the induction region institute direct neighbor of above-mentioned correspondence can be fully utilized to subsequent analysis circuit, and change occur time send drive singal be which drive inductor, to judge the position of touched point.For example, the n-th 1 row in N row induction region and the n-th 2 row induction regions are arranged to share same first inductor, if be positioned at the n-th 1 row, this second inductor corresponding to this induction region on m1 hurdle be same as this second inductor corresponding to this induction region being positioned at the n-th 2 row, m1 hurdle, then can the difference of application of aforementioned the n-th 1 row and the n-th 2 first inductors of row respectively corresponding to direct neighbor induction region, judge which row induction region touched be.
Touch induction installation in above-described embodiment is the quantity reducing by the first inductor by suitable wiring configuration equally.If these first inductors are the reception inductor in mutual capacitance type induction installation, above-mentioned configuration mode also can reach the effect reducing holistic cost.In addition, if this touch-control sensing panel has roughly orthogonal and two of Length discrepancy sides, then this P receives inductor and can be arranged to and correspond to shorter side, and this Q drives inductor can be arranged to corresponding to longer side.
As shown in Figure 8, aforementioned touch induction installation can comprise an analysis module 46 further.The output signal display of the first inductor (42A or 42B) shared when the n-th 1 row and the n-th 2 row induction regions the n-th 1 row or the n-th 2 row induction regions touched, analysis module 46 can be which induction region is touched according to the output signal judgement of these the second inductors (44A ~ 44F).
Another specific embodiment according to the present invention is for comprising the electronic system of the touch induction installation as shown in Fig. 6 (A), Fig. 6 (B) or Fig. 8.Except touch-control sensing panel and these inductors, this electronic system also comprises a control module further, and the analysis result in order to provide according to this analysis module determines one of this electronic system touched rear reaction.For example, if this electronic system is a panel computer, this control module can determine will open or close application according to the action of user on touch-control sensing panel, or is coupled together multiple by touch point, is converted to word/pattern content.The detailed embodiment of the touch-control sensing panel in this electronic system with reference to previous paragraph, can repeat no more.
As mentioned above, the present invention proposes a kind of new touch induction installation hardware structure, by suitable wiring configuration, makes the different driving line of induction/reception lines of induction be able to shared same driver/receiver.When touch-control sensing area size is identical and resolution remains unchanged, the inductive effects that touch induction installation according to the present invention utilizes the driver/receiver of lesser amt can provide same, therefore can reduce the hardware cost of touch induction installation.
By the above detailed description of preferred embodiments, it is desirable to clearly to describe feature of the present invention and spirit, and not with above-mentioned disclosed preferred embodiment, category of the present invention is limited.On the contrary, its objective is wish to contain various change and tool equality be arranged in the present invention institute in the category of the scope of the claims applied for.
