The present invention uses that capacitance type touch-control panel itself had closely connects inducing function; The sensor signal that closely connects that is detected is output as the data that closely connects; And according to closely connecing the mobile trend that data calculates each dimension; Calculate the gesture that closely connects in the middle of the space according to the mobile trend of each dimension again and judge, and then be output as steering order.Wherein, the present invention uses a control module to realize touch-control sensing and closely connects sensing function, and closely connects sensor signal result's the data that closely connects and the coordinate data of representing touch coordinate by unified bus output representative.
Capacitance type touch-control panel mainly divides two types, is respectively surface capacitance type contact panel and projected capacitive touch panel.But projected capacitive touch panel has the function of detecting multi-point touch, yet, in recent years, but also there is manufacturer the surface capacitance type contact panel to be made as the function of detecting multi-point touch.Which kind of capacitance type touch-control panel no matter, no matter all capacitance type touch-control panel structures with multi-point touch detecting function are individual layer or two-layer structure, the present invention is all exercisable.Therefore, below the embodiment of each capacitance type touch-control panel, be merely the cited for purposes of illustration person of the present invention, be not in order to limit the present invention.
At first, please refer to Figure 1A, it is functional block diagram first embodiment that condenser type of the present invention closely connects induction and touch detection device, and it is for being vertically arranged in the embodiment of individual layer with flat triangle.Condenser type closely connects induction and touch detection device 1 includes: contact panel 11, web joint 24 and control module 22.Wherein, Three corner electrode 20-1～20-20 are arranged on the contact panel 11, are that the pairing of Y axle is arranged with three corner electrode 20-1/20-2, three corner electrode 20-3/20-4, three corner electrode 20-5/20-6, three corner electrode 20-7/20-8, three corner electrode 20-9/20-10, three corner electrode 20-11/20-12, three corner electrode 20-13/20-14, three corner electrode 20-15/20-16, three corner electrode 20-17/20-18, three corner electrode 20-19/20-20 respectively.That is, insulated from each other and between three corner electrodes with at least two on X axle and at least two settings of a Y axle, three corner electrodes be used for detecting object near and produce a sensor signal and be used for detecting the touching of object and produce the touching signal.Include in the middle of the control module 22: touch detection circuit 14, closely connect circuit for detecting 16 and control circuit 18.Control module 22 sees through web joint 24 and connects contact panels 11, and has one and closely connect sense mode and a touch detection pattern, when carrying out when closely connecing sense mode, closely connects data according to the sensor signal generation; When carrying out the touch detection pattern, according at least one coordinate data of touching signal calculating object.
In the middle of control module 22, closely connect circuit for detecting 16 and connect contact panel 11, in order to receive sensor signal and to produce the data that closely connects via web joint 24; Touch detection circuit 14 connects contact panel 11 via web joint 24, in order to receive this touching signal and to calculate touch coordinate; Control circuit 18 connects and closely connects circuit for detecting 16 and touch detection circuit 14, in order to controlling the switching execution that closely connects sense mode and touch detection pattern, and this is closely connect data and this touch coordinate transfers out.Must notice that the annexation that closely connects circuit for detecting 16, touch detection circuit 14 and control circuit 18 of Figure 1A is merely the cited for purposes of illustration person of the present invention, be not in order to limit the present invention.
In addition, but the present invention also can closely connect sensing control with the mode of selectivity detecting with the capacitance type touch-control panel of detecting multi-point touch coordinate.For example; Figure 1B is the three corner electrode 20-1/20-2 that selected in the middle of Figure 1A, three corner electrode 20-7/20-8, three corner electrode 20-13/20-14, three corner electrode 20-19/20-20 as the detecting electrode of selecting closely to connect sense mode, and remaining electrode is not done and closely connect detecting and use.The concrete practice is follow-up will be described.
When the time spent that closely connects detecting of being used as capacitance type touch-control panel in the space, the detecting output result who closely connects circuit for detecting 16 has two kinds, is respectively single order and closely connects data and the multistage data that closely connects.Wherein single order closely connect data be object get into capacitance type touch-control panel closely connect inductive spacing after, a data of being exported.Multistagely closely connect then big or small for according to object of data near the difference induction amount that produces of distance, exportable multidigit data, for example, two, three, four ...
Below, will closely connect detecting in what Fig. 3 A～5B explanation output single order closely connect data, and closely connect detecting near what connect data in Fig. 6 A～8E explanation output is many, and, all with the track in the middle of Figure 1A 101 and track 102 as embodiment.Wherein, track 101 is for moving to a left side down by the upper left of contact panel 11.Track 102 is upper right for being moved to by contact panel 11 upper left.Below explanation respectively.
At first, please refer to Fig. 2, contact panel electrode induction range is in the synoptic diagram of Y axle in induction and the touch detection device for utilization condenser type of the present invention closely connects for it, and it is to be output as the embodiment that single order closely connects data.Fig. 2 has explained that each three corner electrode axially sees electrode induction range in the past in A-A, and its maximum detection-sensitive distance is a distance B 1, and the actual sensed distance is as the criterion when looking actual electrode design, and each electrode induction range 41～50 is identical generally.As long as there is object to get in the middle of the electrode induction range 41～50, three corner electrodes 11 promptly can produce sensor signal, promptly can produce single order and closely connect data and closely connect sensing circuit 16.
Fig. 3 A closely connects in induction and the touch detection device for utilization condenser type of the present invention, and in the detecting synoptic diagram of different sequential, it is along the synoptic diagram of A-A section and is output as the embodiment that single order closely connects data object through the Y axle.Fig. 3 A is the synoptic diagram of the track 101 process A-A sections among Figure 1A; Therefore; Three corner electrode 20-1,20-3,20-5,20-7,20-9,20-11,20-13,20-15,20-17 and 20-19 etc. detect object 2 and produce sensor signal at different sequential T1～T6 respectively.
