Description
Technical field
The present invention is related to touch-control system, and especially related to the technology realizing touch controllable function using single-layer electrodes.
Background technology
It is showing improvement or progress day by day with science and technology, in recent years all more and more hommizations of the operation interface of various electronic products.For example,
Through Touch Screen, user directly can operate formula, input message/word/pattern on screen with finger or pointer, save
Go the trouble using input equipment such as keyboard or buttons.In fact, Touch Screen generally by an induction panel and is arranged at sensing
The display composition at panel rear.The position that electronic installation is touched on induction panel according to user, and show at that time
The picture that device is presented, to judge the meaning of this touching, and to execute corresponding operating result.
It is several that existing touch technology is roughly divided into resistance-type, condenser type, induction, Supersonic waves and optical profile type
Class.Capacitance touching control technology can be further divided into self-tolerant (self-capacitance) and mutual capacitance type (mutual- again
Capacitance) two class.With respect to mutual-capacitive touch panel, self-capacitance type touch panel can be by the more simple monolayer electricity of processing procedure
Pole structure is realized, and but there is a problem of being difficult to reach multi-point touch function.Therefore, the range of application of mutual-capacitive touch panel is far high
In self-capacitance type touch panel.
Fig. 1 is a mutual-capacitive touch panel example.As shown in figure 1, induction panel rear is provided with constitutes the saturating of matrix pattern
Prescribed electrode.In this example parallel to X-direction person be drive electrode, parallel to Y-direction person be receiving electrode.Every drive electrode is each
Connect to a driver 12, every receiving electrode is each attached to a receptor 14.In general, these drivers 12 can sequentially
Send drive signal, these receptors 14 then persistently receive induced signal.When touching occurs, corresponding to the driving electricity of touch points
Capacitance Coupled phenomenon occurs between pole and receiving electrode, leads to the induced signal related to mutual capacity to change.According to touching
The position of the driver 12 of drive signal, and the position receptor 14 that induced signal changes is detected is sent during generation

On be not connected.
In order to reduce material cost, many manufacturers are by aforementioned duallayered electrode structure boil down to single layer electrode structure.Existing
In row single layer electrode structure, each prismatic body of dark rhombus electrode 16 and light rhombus electrode 18 is provided in same plane,
Two kinds of electrode parts of overlapping in Fig. 2 (A) are then to be realized with the three-dimensional bridge structure as shown in Fig. 2 (B).In this example,
Connecting line between two dark rhombus electrodes 16 is generally aligned in the same plane with prismatic body, but between two light rhombus electrodes 18
Connecting line is designed to Qu Qizhuan (higher than this plane), to cross over the connecting line that in figure is denoted as dark color.It will thus be seen that it is existing
The single layer electrode structure of row is actually and non-real single layer structure.Because three-dimensional bridge structure fabrication is difficult and yield is low, whole
For body, it is that mutual-capacitive touch panel adopts existing single layer electrode structure may increase the degree of difficulty of fabrication schedule on the contrary and become
This.
On the other hand, in fact, driver 12 and receptor 14 are generally disposed at induction panel with printed circuit board (PCB) phase
In circuit chip even.It is coupled to driving/receiving channel (channel) between induction panel and circuit chip the more, circuit core
The pin number amount of piece also must increase the production cost it is meant that higher therewith.

Specific embodiment
It is a mutual-capacitive touch panel according to one of present invention embodiment, drive electrode therein and receiving electrode are respective
Face profile is rhombus；Fig. 3 (A) is the example arrangement of these electrodes.For purposes of illustration only, Fig. 3 (A) only assumes this mutual capacitance type touch-control
Three drive electrodes (D1～D3) in panel and its neighbouring receiving electrode (R1～R8).
User can be subject to touch, and the electric lines of force affecting is mainly distributed on drive electrode and its neighbouring receiving electrode is mutually flat
Between the sideline of row.For example, between drive electrode D1 and receiving electrode R1, definition has an induction region, drive electrode D1 and connecing
Receiving definition between electrode R2 has another induction region.The rest may be inferred, and drive electrode D1～D3 respectively correspond tos four different senses
Answer region.When the controller (not illustrating) with this mutual-capacitive touch panel Collaboration sends drive signal to drive electrode D1
When, this controller can receive sensing result with season receiving electrode R1, R2, R5, R6, and judges to make according to this four sensing results
Whether user touches four induction regions around drive electrode D1.In the same manner, drive letter when controller sends to drive electrode D3
Number when, this controller can with season receiving electrode R3, R4, R7, R8 receive sensing result, and according to this four sensing results judge
Whether user touches four induction regions around drive electrode D3.
In this embodiment, controller sends a drive signal to drive electrode D1, D3 simultaneously, and in this driving of transmission
The sensing result from receiving electrode R1～R8 is received during signal.Due to eight corresponding induction zones of drive electrode D1 and D3
Domain R1～R8 is each independent, touches multiple induction region therein even with person, controller also can clearly be recognized, will not simultaneously
Obscure, therefore enable the function of multi-point touch.For example, if controller finds the sensing that receiving electrode R5, R4, R8 provide
Changing occurs simultaneously in signal, you can judge that user touches three regions as indicated in Fig. 3 (B) with dotted line simultaneously.
Be can be seen that by above-mentioned operational logic, since controller sends same drive signal to drive electrode D1, D3 simultaneously,
Drive electrode D1, D3 can share the driving passage connecting to controller.Pass through different drivings compared to making drive electrode D1, D3
Passage connects to controller, and common drive passage can save the foot position of controller place chip.Even if not common drive passage, control
Device processed also can send drive signal to drive electrode D1, D3 simultaneously, to save the time scanning whole mutual-capacitive touch panel.Letter
Yan Zhi, two electrodes sharing same passage must be for being driven/receiving sensing simultaneously, and two electrodes of unshared same passage are also
May be driven simultaneously/receive sensing.
On the other hand, for avoiding controller to obscure sensing result, when drive electrode D1, D3 share the drive connecting to controller
Dynamic passage, or any two receptions when controller sends drive signal to drive electrode D1, D3 simultaneously, in receiving electrode R1～R8
Electrode must share the receiving channel connecting to controller.In other words, receiving electrode R1～necessary between R8 and controller
It is provided with eight different receiving channels, correspond respectively to receiving electrode R1～R8.In practice, controller can receive to be derived from simultaneously and connect
Receive the sensing result of electrode R1～R8, also can be in this eight sensing results of period received in sequence sending drive signal.
Relatively, in this embodiment, because drive electrode D1, D2 correspond to receiving electrode R2, R6 jointly, controller is not
Drive signal can be sent to drive electrode D1, D2 simultaneously.If controller sends drive signal to drive electrode D1, D2 simultaneously, when
Controller finds that change in the induced signal that receiving electrode R2 provides, and which that resolution is in Fig. 3 (C) controller will be unable to
Touched by user with the induction region that dotted line indicates.
Fig. 4 (A) assumes more drive electrodes in mutual-capacitive touch panel according to an embodiment of the invention further
And its neighbouring receiving electrode.In this embodiment, the electrode of common-use tunnel is marked by identical title.With two in Fig. 4 (A)
As a example individual drive electrode D1, four receiving electrodes (R1, R2, R5, R6) corresponding to the drive electrode D1 in left side and corresponding to the right side
Four receiving electrodes (R3, R4, R7, R8) of the drive electrode D1 of side are not repeated completely, and the reception of this eight receiving electrodes is led to
Road is also different.In other words, as long as the receiving electrode itself corresponding to two drive electrodes and the receiving channel being connected
Neither repeat, this two drive electrodes just can share same driving passage.
For changing an angle, two drive electrodes driving in the controlled device of different time points just can physically share at least
One receiving electrode (drive electrode D1, D3 of the such as leftmost side shares receiving electrode R5, R6), more precisely, can share connection
To the receiving electrode of same receiving channel, (it is different but connect and connect to identical that drive electrode D1, D5 of the such as leftmost side share entity
Receive receiving electrode R1, R2, R5, R6 of passage).
It should be noted that, designer can according to practice demand (such as cost or coiling demand) optionally allow drive electrode/
Receiving electrode common drive passage/receiving channel.Include the drive of common drive passage in embodiment shown in Fig. 4 (A) simultaneously
Moving electrode and the receiving electrode of shared receiving channel, and the quantity of maximize common drive passage and shared receiving channel.?
In the case of completely unshared passage, originally need 12 different driving passages and 20 different receiving channels；Using root
It is thus only necessary to 6 drivings after the quantity of common drive passage and the shared receiving channel of maximizing according to the shared concept of the present invention
Passage and 8 receiving channels.In another embodiment, designer can only make drive electrode common drive passage, or only makes
Receiving electrode shares receiving channel.In another embodiment, designer also can only make part drive electrode common drive passage, or
Person is only to make part receiving electrode share receiving channel, self-evident.
Fig. 4 (B) presents one of these interelectrode driving passage/receiving channel wirings embodiment further.It is worth note
Meaning, these drive electrodes (D1～D6), receiving electrode (R1～R8) and passage all may be placed at same plane, and all
The wiring driving passage and receiving channel will not overlap mutually, therefore do not need the three-dimensional bridge structure in prior art.Real
In business, the quantity of electrode member, shape and arrangement mode are neither limited with the embodiment shown in Fig. 4 (B), and these wirings can quilt
More densely packed configure, to shorten the spacing of adjacent electrode elements.It should be noted that, being connected of passage can be in contact panel and control
Realize on printed circuit board (PCB) between device processed, the circuit trace not being limited to contact panel itself is just connected.

The demands such as the pin number amount between multi-point touch, minimizing panel and circuit chip.
It is a mutual-capacitive touch panel according to another embodiment of the present invention, drive electrode therein and receiving electrode are each
Face profile be a triangle；Fig. 5 (A) shows the configuration of electrode in an embodiment.For keeping drawing clear, connection electrode and
The passage of controller is not illustrated in Fig. 5 (A)；Numbering identical electrode is connected to a passage.The electrode of numbering a～i is solid
Fixed receiving electrode, the electrode of numbering A～F is fixing drive electrode, the electrode of numbering 1～8 then for movable electrode (sometimes by
Switch to receiving electrode, be sometimes switched to drive electrode).Movable electrode 1～8 is set as by Fig. 5 (B) in order to controller to be described
Receiving electrode and the running through same six drive electrode A driving channels drive Left half-plane.In each electrode in Fig. 5 (B)
Between the solid black round dot that indicated be the center of the induction region that can detect under this situation that user touches.Fig. 5 (C)
In order to illustrate that movable electrode 1,5 is set as drive electrode and movable electrode 3,7 is set as fortune during receiving electrode by controller
Make, the solid black round dot marked in figure is the center of the induction region that can detect under this situation that user touches.
Drive drive electrode A～F and movable electrode 1～8 through timesharing in turn, you can completely sense whole mutual-capacitive touch panel.Its
The control logic of his electrode can the rest may be inferred, repeats no more.
As long as it was earlier mentioned, receiving electrode itself corresponding to two drive electrodes or the receiving channel that connected are neither heavy
Multiple, this two drive electrodes just can share same driving passage.As long as additionally, the drive electrode corresponding to two receiving electrodes will not
It is driven via storage capacitors simultaneously, this two receiving electrodes just can share same receiving channel.Can be seen that, above-described embodiment needs altogether by Fig. 5 (A)
6 are wanted to drive passage, 9 receiving channels and 8 changeable channels；The quantity of these passages is obviously less than the quantity of electrode.With front
One embodiment identical is, these electrodes and passage all may be placed at same plane it is not necessary to bridge structure.
