Embodiment
The driving method of a kind of contact panel with anisotropy material that this exposure below is provided and the embodiment of device.One embodiment of driving method is based at least two adjacent conducting end being carried out simultaneously drive actions, at least two relative conducting end being carried out the mode that drive actions and above-mentioned conducting end are all carried out drive actions simultaneously simultaneously.So, it can be assisted or reach: the detection of touch point or the calculating of the coordinate of touch point.Also can help the resolution that improves the coordinate that detects the touch point gained.
For embodiment that this exposure is described relation, the problem that the resolution of doing the identification that drive actions produces to single conducting end has error at first is discussed at this with the resolution of the coordinate that detects the touch point gained.
Fig. 1 illustrates an embodiment of the contact panel with anisotropy material, wherein illustrates a conducting end of contact panel is carried out drive actions.Contact panel 10 has anisotropy material film 100 like carbon nanotube film.For example, contact panel comprises that one has an anisotropy material film 100 and a base material, has anisotropy material film 100 and is arranged on the base material.For example, CNT (CNT) film directly is attached on the transparency carrier and processes; Its employed CNT is with the synthetic SWNT (SWCNT) of CVD, is coated on the PET base material after processing the CNT slurry, becomes the CNT film.In addition, more can add upper top cover (cover lens) at the CNT film.
Because the characteristic of anisotropy material film 100; Contact panel 10 is gone up because the bigger resistance of tool at a first direction (or being called directions X); Event is essentially non-conductive, and goes up because of the less resistance of tool in a second direction (or being called the Y direction), so have electric conductivity in fact.At a plurality of first conducting end P1-1 to P1-N (below be abbreviated as P1) that have row on the directions X of a side with anisotropy material film 100; And opposite side has a plurality of second conducting end P2-1 to P2-N (below be abbreviated as P2) of row; These second conducting end P2 has on the anisotropy material film 100 with relative being arranged on of these first conducting end P1 on the Y direction, that is for example the second conducting end P2-1 is relative with the first conducting end P1-1.Definition one touch area 190 between the first conducting end P1 and the second conducting end P2, to let the user make the input action of touch-control, the touch-control action of for example pushing, pulling and so on.
Meaning shown in Figure 1 is carried out drive actions to a conducting end of contact panel 10; For example be to the first conducting end P1-K; Do earlier to discharge again after the charging; Remaining conducting end then can make its like ground connection, connect an end current potential or a suspension joint, wherein, first conducting end and the second corresponding conducting end thereof of drive actions carried out in K representative.The equipotential line of formed electrostatic field is shown in the dotted line of Fig. 1 when the first conducting end P1-K is full of electricity, wherein also takes place like the phenomenon of the leakage current of tool arrow representative.
Drive actions is further again, can when discharge, detect action, for example is to utilize electric capacity digital quantizer (Capacitance-to-Digital converter) to detect the signal intensity of the first conducting end P1-K, thereby produces value corresponding.Show that like Fig. 2 A near the first conducting end P1-K, produced a touch point TP1, A moves along track, promptly the Building X is marked constant and is moved up near the second conducting end P2-K along the Y direction; The relation that changes with the Building Y mark of touch point TP1 of the signal intensity that can detect accordingly shown in the curve S A among Fig. 2 B.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.The curve S A of comparison diagram 2B and SB can know that the touch point distance 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.This shows that the Building Y target variation that utilizes the signal intensity of the first conducting end P1-K to estimate touch point can cause error.For example shown in Fig. 2 C, when a touch point TP3 turns right when advancing along the track R (solid line) of reality, but become fluctuation shown in the dotted line curve as changing according to the path CP of detected signal intensity after calculating.So the resolution of making the coordinate of the touch point that drive actions draws to single conducting end has serious error.
And, carry out drive actions at least two adjacent conductive ends according to this exposure, can effectively improve above-mentioned problem.The synoptic diagram of Fig. 3 A at least two conducting end P1-3 among the embodiment of contact panel 10 and P1-4 are carried out drive actions.In Fig. 3 A, mild by two first conducting end P1-3 of charging simultaneously and the equipotential line person more shown in Figure 1 on directions X between the P1-4.So on the touch area between the first conducting end P1-3, P1-4, the second conducting end P2-3 and the P2-4, produced the equipotential line that gradient is arranged on the Y direction.
As the test mode of Fig. 2 A, Fig. 3 B is shown in that two touch point TP1, TP2 move along track A and B respectively under the drive actions shown in Fig. 3 A.And present embodiment hypothesis K=3; Then Fig. 3 C illustrates under the drive actions shown in Fig. 3 A this two conducting end P1-3 and P1-4 is detected the relation of a signal intensity of gained with the Building Y mark variation of touch point; Wherein the Building Y of first conducting end is marked the Building Y mark that is assumed to be 0, the second conducting end and is assumed to be a certain integer.In Fig. 3 C, curve S A ' and SB ' correspond to two touch point TP1 and TP2 respectively.When less (promptly more near this two first conducting end) marked in the Building Y of touch point, curve S A ' and SB ' can be considered overlapping; When touch point Building Y mark (was promptly healed away from this two first conducting end) greatly, curve S A ' and SB ' were still variant, but compared to Fig. 2 B, this difference has been dwindled.
So; If two second conducting end P2-3 and P2-4 are carried out the action that elder generation charges and discharges; And in discharging action, detect; Then conducting end P2-3 and P2-4 detect the relation of a signal intensity of gained with the Building Y mark variation of two touch point TP1 and TP2; Can be similar with above-mentioned situation, promptly more near two second conducting end P2-3 and P2-4 (being that touch point Building Y mark is bigger) then the change curve of signal intensity be tending towards overlapping, more leave this two conducting end (being that touch point Building Y mark is less) then the change curve of signal intensity still have some differences.
Hence one can see that; In order to try to achieve the Building Y mark of more accurate touch point; Can be respectively carry out drive actions simultaneously for conducting end of at least two first and at least two second each group of conducting end, thus according to detected a plurality of signal intensities right numerical value insert or other calculation modes are tried to achieve the Building Y mark of touch point with interior.Please refer to shown in Figure 4ly, propose a kind of embodiment of driving method of contact panel, it can be assisted or reach: the detection of touch point or the calculating of the coordinate of touch point.The method comprises that step is following: shown in step S410, the contact panel with anisotropy material is provided, contact panel as shown in Figure 1.Shown in step S420; According at least two the first adjacent conducting end of contact panel with and relative and adjacent at least two second conducting end in comprise a combination of at least two conducting end and comprise a plurality of combinations of a combination of whole conducting end, respectively the conducting end that is comprised in these combinations is carried out drive actions simultaneously.
