Embodiment
The a kind of of this exposure is below provided to have the driving method of the contact panel of anisotropic material and the embodiment of device.One embodiment of driving method based on carrying out drive actions to adjacent at least two conducting end simultaneously, relative at least two conducting end are carried out simultaneously to the mode that drive actions and above-mentioned conducting end all carry out drive actions simultaneously.So, it can be assisted or reach: the calculating of the detection of touch point or the coordinate of touch point.Also the resolution improving the coordinate detecting touch point gained can be helped.
In order to embodiment that this exposure is described and the relation of resolution of coordinate detecting touch point gained, at this, first problem that resolution doing the identification that drive actions produces for single conducting end has error is discussed.
Fig. 1 illustrates an embodiment of a contact panel with anisotropic material, wherein illustrates to carry out drive actions to a conducting end of contact panel.Contact panel 10 has anisotropic material film 100 as carbon nanotube film.Such as, contact panel comprises one and has anisotropic material film 100 and a base material, has anisotropic material film 100 and is arranged on base material.Such as, CNT (CNT) film is directly pasted on the transparent substrate and makes; Its CNT used is with the Single Walled Carbon Nanotube (SWCNT) of CVD synthesis, is coated on PET base material, becomes carbon nanotube thin film after making CNT slurry.In addition, more upper top cover (coverlens) can be added in carbon nanotube thin film.
Due to the characteristic of anisotropic material film 100, contact panel 10 is at the upper resistance larger because of tool of a first direction (or being called X-direction), therefore be essentially non-conductive, and at the upper resistance less because of tool of a second direction (or being called Y-direction), therefore in fact there is electric conductivity.The X-direction of side with anisotropic material film 100 has multiple first conducting end P1-1 to P1-N (hereinafter abbreviated as P1) of row, and opposite side has multiple second conducting end P2-1 to P2-N (hereinafter abbreviated as P2) of row, these second conducting end P2 have in anisotropic material film 100 with relative being arranged on of these the first conducting end P1 in the Y direction, that is such as the second conducting end P2-1 is relative with the first conducting end P1-1.The touch-control action defining a touch area 190 between first conducting end P1 and the second conducting end P2, with the input action allowing user make touch-control, such as, press, pull and so on.
A conducting end to contact panel 10 illustrated in Figure 1 carries out drive actions, such as to the first conducting end P1-K, discharge again after first charging, remaining conducting end then can make it as ground connection, connect end current potential or a suspension joint, wherein, the first conducting end of drive actions and the second conducting end of correspondence thereof are being carried out in K representative.As indicated by the dashed line in figure 1, the phenomenon of the leakage current wherein also representated by tool arrow occurs the equipotential line of the electrostatic field formed when the first conducting end P1-K is full of electricity.
Drive actions is further again, can when discharging, and carrying out detection action, such as, is the signal intensity utilizing capacitive digital converter (Capacitance-to-Digitalconverter) to detect the first conducting end P1-K, thus produces corresponding numerical value.As Fig. 2 A shows, create a touch point TP1, move along track A near the first conducting end P1-K, namely Building X is marked constant and is moved up near the second conducting end P2-K along the Y direction; The signal intensity that corresponding ground can detect marks the relation of change as shown in the curve S A in Fig. 2 B with the Building Y of touch point TP1.Another touch point TP2 produces between the first conducting end P1-K and P1-(K+1) again, moves along the track B parallel with track A, and the signal intensity of detection is represented by curve S B with the Building Y mark variation relation of touch point TP2.Curve S A and the SB of comparison diagram 2B are known, and touch point distance the first conducting end P1-K is nearer, and signal intensity is stronger, and vice versa; But for the numerical value of same signal intensity, but can be different because of touch point Building X mark, and produce different numerical value.As can be seen here, the signal intensity of the first conducting end P1-K is utilized can to cause error to the Building Y target change estimating touch point.Such as shown in Fig. 2 C, when a touch point TP3 along the track R (solid line) of reality turn right advance time, according to the signal intensity detected as calculated after path CP but become curve as shown by dashed lines as fluctuation change.So the resolution making the coordinate of the touch point that drive actions draws for single conducting end has serious error.
And according to this exposure, carry out drive actions at least two adjacent conducting end, can effectively improve above-mentioned problem.Fig. 3 A is the schematic diagram at least two conducting end P1-3 in the embodiment of contact panel 10 and P1-4 being carried out to drive actions.In figure 3 a, by the equipotential line between two the first conducting end P1-3 and P1-4 charging simultaneously, comparatively that shown in Figure 1 is mild in the X direction.So on the touch area between the first conducting end P1-3, P1-4, the second conducting end P2-3 and P2-4, create equipotential line Y-direction having gradient.
As the test mode of Fig. 2 A, under Fig. 3 B is shown in the drive actions shown in Fig. 3 A, two touch point TP1, TP2 move along track A and B respectively.And the present embodiment hypothesis K=3, then Fig. 3 C illustrates the relation of a signal intensity with the Building Y mark change of touch point this two conducting end P1-3 and P1-4 being detected to gained under the drive actions shown in Fig. 3 A, wherein the Building Y mark of the first conducting end is assumed to be 0, and the Building Y mark of the second conducting end is assumed to be a certain integer.In fig. 3 c, curve S A ' and SB ' corresponds to two touch point TP1 and TP2 respectively.When Building Y mark less (namely more near this two first conducting end) of touch point, curve S A ' and SB ' can be considered overlapping; When touch point Building Y mark comparatively large (namely more away from this two first conducting end), curve S A ' and SB ' is still variant, but compared to Fig. 2 B, this difference reduces.
So, if to the action that two second conducting end P2-3 and P2-4 first charge and discharge, and detect in discharging action, then conducting end P2-3 and P2-4 detects the relation of a signal intensity with the Building Y mark change of two touch point TP1 and TP2 of gained, can be similar to the above case, namely more near two second conducting end P2-3 and P2-4 (i.e. touch point Building Y mark larger) then the change curve of signal intensity be tending towards overlapping, more leave this two conducting end (namely touch point Building Y is marked less) then the change curve of signal intensity still have some differences.
It can thus be appreciated that, in order to try to achieve the Building Y mark of more accurate touch point, the conducting end that can respectively organize at least two first and at least two the second conducting end respectively carries out drive actions simultaneously, thus tries to achieve the Building Y mark of touch point with interpolation or other calculation modes according to the right numerical value of the multiple signal intensities detected.Please refer to shown in Fig. 4, propose a kind of embodiment of driving method of contact panel, it can be assisted or reach: the calculating of the detection of touch point or the coordinate of touch point.It is as follows that the method comprises step: as shown in step S410, provides a contact panel with anisotropic material, contact panel as shown in Figure 1.As shown in step S420, at least two adjacent first conducting end of foundation contact panel and its at least two relative and adjacent the second conducting end comprise a combination of at least two conducting end and comprise multiple combinations of combining of whole conducting end, carry out drive actions respectively to the conducting end comprised in these combinations simultaneously.

In addition, in certain embodiments, for the combination shown in such as Fig. 5 A or Fig. 5 B, when detecting the signal intensity of these conducting end comprised in this combination, can reach by different modes.Such as shown in Fig. 7 A, for the combination of these at least two the first conducting end (P1-1 to P1-N), indivedual signal intensity detecting these conducting end comprised in this combination simultaneously.Such as shown in Fig. 7 A, two the first conducting end P1-K, P1-(K+1) are carried out individually to the detection of signal intensity by use two capacitive digital converter 700 simultaneously.Again such as shown in Fig. 7 B, for the combination of these at least two the first conducting end (P1-1 to P1-N), detecting signal intensity when these conducting end of comprising are coupled in this combination, such as, is by making two adjacent conducting end be coupled to a capacitive digital converter to carry out detection signal strength.Again such as shown in Fig. 7 C, for the combination (when such as having the first conducting end P1-1 to P1-N of three or more) of these at least two the first conducting end P1-1 to P1-N, detecting step comprises: detect this combination at least both couple time signal intensity.In the practice of anticipating as seen in figure 7 c, there are many implementations, such as, in 3 the first conducting end P1-1 to P1-N, select two groups of P1-K, P1-(K+1) and detect these two groups other signal intensities simultaneously.Such as shown in Fig. 7 C, by making two capacitive digital converter to carry out detecting the signal intensity of news three the first conducting end.In the example of above-mentioned 7A or 7C figure, two numerical value wherein obtained by two capacitive digital converter 700 can be made such as addition process thus obtain corresponding numerical value in the process of postorder.
In addition, Fig. 8 is a kind of calcspar of an embodiment of touch panel module.In fig. 8, touch panel module 80 comprises a contact panel 10 and drive unit 800.All conducting end of contact panel 10 are all coupled to drive unit 800, such as, be through flexible circuit board or printed circuit board (PCB).Drive unit 800 comprises control module 810 and a sensing cell 820.Control module 810, in order to control the drive actions to contact panel 10, can realize each embodiment of type of drive described above.Sensing cell 820 coordinates the drive actions of control module 810, in time detects the signal intensity of these conducting end, to produce corresponding numerical value.In some implementations, drive unit 800, according to the output numerical value of sensing cell 820, can produce the coordinate of the touch point that touch area 190 senses according to this, or the parameter that other touch-controls are relevant.
