Description
Technical field
The present invention is relevant to touch-control system, and especially to utilize single-layer electrodes to realize the technology of touch controllable function relevant.
Background technology
Along with science and technology is showing improvement or progress day by day, all more and more hommizations of the operation interface of various electronic products in recent years.For example, see through Touch Screen, user can directly make formula, input message/word/pattern with finger or pointer in on-screen options, saves the trouble of input medias such as using keyboard or button.In fact, Touch Screen is comprised of an induction panel and the display that is arranged at induction panel rear conventionally.The position that electronic installation is touched on induction panel according to user, and the picture that display presents at that time, judge the meaning of this touching, and carry out corresponding operating result.
Existing touch technology is roughly divided into resistance-type, condenser type, induction, ultrasonic formula and several classes of optical profile type.Capacitive touch control techniques can be further divided into again self-tolerant (self-capacitance) and mutual appearance formula (mutual-capacitance) two classes.With respect to mutual appearance formula contact panel, self-tolerant contact panel can be realized by the more simple single-layer electrodes structure of processing procedure, but has the problem that is difficult to reach multi-point touch function.Therefore the range of application of, holding mutually formula contact panel is far above self-tolerant contact panel.
Fig. 1 is a mutual appearance formula contact panel example.As shown in Figure 1, induction panel rear is provided with the transparency electrode that forms matrix pattern.The person that is parallel to directions X in this example is drive electrode, is parallel to Y-direction person for receiving electrode.Every drive electrode is connected to a driver 12 separately, and every receiving electrode is connected to a receiver 14 separately.Generally speaking, these drivers 12 can sequentially be sent driving signal, and 14 of these receivers continue to receive induced signal.When touching occurs, corresponding to there will be capacitive coupling phenomenon between the drive electrode of touch points and receiving electrode, cause the induced signal relevant to mutual capacity to change.While occurring according to touching, send the position of the driver 12 that drives signal, and the position that the receiver 14 that induced signal changes detected, subsequent conditioning circuit can judge the coordinate of touch points in X/Y direction.
Traditionally, drive electrode and receiving electrode are the transparency electrodes that is separately positioned on Different Plane.Fig. 2 (A) is the most widely used rhombus electrode pattern at present.Building Y is marked identical dark rhombus electrode 16 and is connected in series each other, forms the drive electrode that is parallel to directions X; Building X is marked identical light rhombus electrode 18 and is connected in series each other, forms the drive electrode that is parallel to Y-direction.Because dark rhombus electrode 16 and light rhombus electrode 18 are to be positioned at Different Plane, so be connected on the part entity that two kinds of electrodes overlap in drawing.
In order to reduce material cost, many manufacturers are by aforementioned two-layer electrode structure boil down to single-layer electrodes structure.In existing single-layer electrodes structure, each rhombus main body of dark rhombus electrode 16 and light rhombus electrode 18 is arranged on same plane, and the part that two kinds of electrodes overlap in Fig. 2 (A) is to realize with the three-dimensional bridge structure as shown in Fig. 2 (B).In this example, connecting line and rhombus main body between two dark rhombus electrodes 16 are positioned at same plane, but the connecting line of 18, two light rhombus electrodes is designed to Qu Qizhuan (higher than this plane), to be denoted as dark connecting line in leap figure.Can find out thus, in fact existing single-layer electrodes structure is not real single layer structure.Because three-dimensional bridge structure fabrication is difficult and yield is low, generally speaking, for mutual appearance formula contact panel adopts existing single-layer electrodes structure may increase on the contrary degree of difficulty and the cost of manufacturing course.
On the other hand, in fact, driver 12 is arranged in the circuit chip being connected with printed circuit board (PCB) with induction panel conventionally with receiver 14.Be coupled to driving/receiving cable (channel) between induction panel and circuit chip the more, the pin number amount of circuit chip also must increase thereupon, means higher production cost.

Embodiment
According to one embodiment of the invention, be a mutual appearance formula contact panel, drive electrode wherein and receiving electrode face profile is separately rhombus; The example arrangement that Fig. 3 (A) is these electrodes.For ease of explanation, Fig. 3 (A) only presents three drive electrodes (D1 ~ D3) and the contiguous receiving electrode (R1 ~ R8) thereof in this mutual appearance formula contact panel.
Can be subject to line of electric force that user touches impact is mainly distributed between the sideline that drive electrode and contiguous receiving electrode thereof be parallel to each other.For example, between drive electrode D1 and receiving electrode R1, definition has an induction region, and between drive electrode D1 and receiving electrode R2, definition has another induction region.The rest may be inferred, and drive electrode D1 ~ D3 is separately corresponding to four different induction regions.When the controller (not illustrating) that holds mutually therewith formula contact panel Collaboration sends while driving signal drive electrode D1, this controller can receive induction result with seasonal receiving electrode R1, R2, R5, R6, and judges according to these four induction results whether user touches drive electrode D1 four induction regions around.In like manner, when controller sends driving signal to drive electrode D3, this controller can receive induction result with seasonal receiving electrode R3, R4, R7, R8, and judges according to these four induction results whether user touches drive electrode D3 four induction regions around.
In this embodiment, controller sends one to drive electrode D1, D3 simultaneously and drives signal, and receives the induction result from receiving electrode R1 ~ R8 when sending this driving signal.Due to drive electrode D1 and corresponding eight the induction region R1 ~ R8 of D3 independent separately, even if user touches a plurality of induction regions wherein simultaneously, controller also can clearly recognize, unlikelyly obscures, and therefore can realize the function of multi-point touch.For example, if controller is found the induced signal that receiving electrode R5, R4, R8 provide, occur changing simultaneously, can judge that user touches three regions that indicate with dotted line as in Fig. 3 (B) simultaneously.
By above-mentioned operational logic, can be found out, since controller sends same driving signal to drive electrode D1, D3 simultaneously, drive electrode D1, D3 can share the driving passage that is connected to controller.Compared to making drive electrode D1, D3 see through different driving passages, be connected to controller, common drive passage can be saved the pin position of controller place chip.Even common drive passage not, controller also can send and drive signal drive electrode D1, D3 simultaneously, to save the time of the whole mutual appearance formula contact panel of scanning.In brief, two electrodes that share same passage must be for be activated/receive induction simultaneously, and two electrodes of shared same passage also may not be activated simultaneously/receive induction.
On the other hand, for avoiding controller, obscure induction result, when drive electrode D1, D3 share the driving passage that is connected to controller, or controller is while send driving signal to drive electrode D1, D3 simultaneously, any two receiving electrodes in receiving electrode R1 ~ R8 can not share the receiving cable that is connected to controller.Easy speech, between receiving electrode R1 ~ R8 and controller, must be provided with eight different receiving cables, correspond respectively to receiving electrode R1 ~ R8.In practice, controller can receive the induction result from receiving electrode R1 ~ R8 simultaneously, also can during transmission driving signal, sequentially receive these eight induction results.
Relatively, in this embodiment, because drive electrode D1, D2 are jointly corresponding to receiving electrode R2, R6, controller can not send and drive signal drive electrode D1, D2 simultaneously.If controller send to drive signal to drive electrode D1, D2 simultaneously, when controller, to find the induced signal that receiving electrode R2 provides and occur changing, it is which in Fig. 3 (C) induction region that indicates with dotted line is touched by user that controller cannot be differentiated.
Fig. 4 (A) further presents more drive electrodes and the contiguous receiving electrode thereof holding mutually according to an embodiment of the invention in formula contact panel.In this embodiment, the electrode of common-use tunnel is marked by identical title.Two drive electrode D1 of take in Fig. 4 (A) are example, corresponding to four receiving electrodes (R1, R2, R5, R6) of the drive electrode D1 in left side with corresponding to four receiving electrodes (R3, R4, R7, R8) of the drive electrode D1 on right side, completely do not repeat, and the receiving cable of these eight receiving electrodes is also different.In other words, the neither repetition of receiving cable that needs only two drive electrodes corresponding receiving electrode itself and connect, these two drive electrodes just can share same driving passage.
Change an angle, two drive electrodes that drive at the controlled device of different time points just can share at least one receiving electrode (for example drive electrode D1, the D3 of the leftmost side share receiving electrode R5, R6) on entity, or rather, can share the receiving electrode (it is different but be connected to receiving electrode R1, R2, R5, the R6 of identical receiving cable that for example drive electrode D1, the D5 of the leftmost side share entity) that is connected to same receiving cable.
Should be noted that, deviser can for example, optionally allow drive electrode/receiving electrode common drive passage/receiving cable according to practice demand (cost or coiling demand).In embodiment shown in Fig. 4 (A), include the drive electrode of common drive passage and the receiving electrode of shared receiving cable simultaneously, and the quantity of maximize common drive passage and shared receiving cable.Completely not common-use tunnel in the situation that, originally need 12 different driving passages and 20 different receiving cables; Employing, according to after the quantity of shared concept maximization common drive passage of the present invention and shared receiving cable, only needs 6 to drive passage and 8 receiving cables.In another embodiment, deviser can only make drive electrode common drive passage, or only makes receiving electrode share receiving cable.In another embodiment, deviser also can only make part drive electrode common drive passage, or only makes part receiving electrode share receiving cable, self-evident.
Fig. 4 (B) has further presented an embodiment of these interelectrode driving passages/receiving cable wiring.It should be noted that, these drive electrodes (D1 ~ D6), receiving electrode (R1 ~ R8) and passage all can be arranged at same plane, and all driving passages and the wiring of receiving cable can not overlap mutually, therefore do not need the three-dimensional bridge structure in prior art.In practice, the quantity of electrode member, shape and arrangement mode are neither to be limited with the embodiment shown in Fig. 4 (B), and these wirings can be configured more thick and fast, to shorten the spacing of adjacent electrode element.Should be noted that, being connected of passage can realize on the printed circuit board (PCB) between contact panel and controller, and the circuit trace that is not limited to contact panel itself is just connected.
From illustrating above, mutual appearance formula contact panel according to the present invention can be taken into account and adopt single-layer electrodes structure, realizes multi-point touch, reduce the demands such as pin number amount between panel and circuit chip.
Be a mutual appearance formula contact panel according to another embodiment of the present invention, drive electrode wherein and receiving electrode face profile is separately a triangle; Fig. 5 (A) shows the configuration of electrode in an embodiment.For keeping drawing clear, the passage of connecting electrode and controller is not illustrated in Fig. 5 (A); Number identical electrode and be connected to same passage.The electrode of numbering a ~ i is fixing receiving electrode, and the electrode of numbering A ~ F is fixing drive electrode, and numbering 1 ~ 8 electrode is movable electrode (be sometimes switched to receiving electrode, be sometimes switched to drive electrode).Fig. 5 (B) is in order to illustrate controller movable electrode 1 ~ 8 is set as to receiving electrode and to see through the running of six drive electrode A of same driving channels drive Left half-plane.In Fig. 5 (B), in the solid black round dot indicating between each electrode, can detect the center of the induction region that user touches under situation for this reason.The running of Fig. 5 (C) when illustrating that controller is set as movable electrode 1,5 drive electrode and movable electrode 3,7 is set as to receiving electrode, the solid black round dot indicating in figure can detect the center of the induction region that user touches under situation for this reason.See through timesharing in turn and drive drive electrode A ~ F and movable electrode 1 ~ 8, can the whole mutual appearance formula contact panel of complete sensing.The steering logic of other electrodes can the rest may be inferred, repeats no more.
The neither repetition of receiving cable as discussed previously, to need only two drive electrodes corresponding receiving electrode itself or connect, these two drive electrodes just can share same driving passage.In addition,, as long as the corresponding drive electrode of two receiving electrodes can not driven simultaneously, these two receiving electrodes just can share same receiving cable.By Fig. 5 (A), can be found out, above-described embodiment needs 6 to drive passage, 9 receiving cables and 8 changeable channels altogether; The quantity of these passages is obviously less than the quantity of electrode.Identical with previous embodiment, these electrodes and passage all can be arranged at same plane, do not need bridge structure.
Except aforementioned mutual appearance formula contact panel (pattern can be as shown in Fig. 4 (A) or Fig. 5 (A)), further to comprise the mutual appearance formula touch-control system of a controller according to another embodiment of the present invention.For example, mutual appearance formula contact panel according to the present invention can be integrated in mobile communication equipment, panel computer, PC or the interactive information display board isoelectronic series system that comprises touching control panel controller.
As mentioned above, in order taking into account, to adopt single-layer electrodes structure, realize multi-point touch, to reduce the demands such as pin number amount between panel and circuit chip, the present invention proposes a kind of new mutual appearance formula contact panel and holds mutually formula touch-control system, adopt the single-layer electrodes that does not need three-dimensional bridge structure, and by suitably configuration driven electrode and receiving electrode, make electrode can shared panel and circuit chip between passage.Compared to prior art, according to panel of the present invention and system, can effectively reduce processing procedure difficulty, save production cost, and the function of multi-point touch is provided.
By the above detailed description of preferred embodiments, hope can be known description feature of the present invention and spirit more, and not with the above-mentioned preferred embodiment being disclosed, category of the present invention is limited.On the contrary, its objective is that hope can contain in the category of the scope of the claims of being arranged in of various changes and tool equality institute of the present invention wish application.
