Embodiment
Some exemplary embodiments embodying this case feature & benefits describe in detail in the explanation of back segment.Be understood that this case can have various changes in different aspects, it neither departs from the scope of this case, and explanation wherein and graphic be use when explain in itself, and be not used to limit this case.
Refer to Fig. 1, its be this case for improve known techniques disappearance develop out the first embodiment schematic diagram about touch electrode structure, mainly carried out substrate 10 on the surface with the form of single conductive layer, this substrate 10 can be the display pannel of portable equipment or Wearable device.And the present embodiment system with substrate 10 for circle is described, but not as limit.As seen from Figure 1, the touch electrode structure of this case by organizing induction electrode to forming, can be covered with the border circular areas of this substrate 10 more.The composition that wherein each group induction electrode is right is all similar, be described 11 for first group of induction electrode, it is the first induction electrode 111 and the second induction electrode 112 including external form and be made up of four camber claw-likes, and both interlock adjacent across the first gap 110 and form the first covering of the fan 119.For Fig. 1, border circular areas is divided into quarter, and the configuration of each 1/4th equal portions is all identical, and in Fig. 1, in electrode, difform lines are only the distribution of clear difference Different electrodes, does not represent the difference had between these electrodes on any material.So this quadrant amplifies to carry out clearer explanation in Fig. 2 system.
The first covering of the fan 119 in Fig. 2 is the first induction electrode 111 and the second induction electrode 112 are separated by the first gap 110, first gap 110 mainly (has seven by many camber lines in this example, 1101 ~ 1107) form and so the area of the first covering of the fan 119 can be divided into two parts, and be respectively equipped with the first induction electrode 111 and the second induction electrode 112 be made up of four camber claw-like electrodes in two part areas.Four camber claw-like electrodes in first induction electrode 111 are all connected to the first signal wire 121 in signal line group 12, and four camber claw-like electrodes in the second induction electrode 112 are all connected to the secondary signal line 122 in signal line group 12.In this embodiment, the first signal wire 121 is the base portion being connected to each camber claw-like electrode in the first induction electrode 111, but not as limit.In enforcement, in first induction electrode 111, the base portion of all camber claw-like electrodes also can be electrically connected, and the first signal wire 121 only can be connected to one of them tip of those camber claw-like electrodes in the first induction electrode 111, can reach the object controlling the first induction electrode 111 by the first signal wire 121 so too.Camber claw-like electrode in second induction electrode 112 and the connected mode of secondary signal line 122 can be same or similar in the connected mode of the first induction electrode 111 and the first signal wire 121.In one embodiment, signal line group 12 only can be arranged at the right side of those induction electrodes, now, first signal wire 121 can be connected to the base portion of each camber claw-like electrode in the first induction electrode 111, and the base portion system of all camber claw-like electrodes is electrically connected in the second induction electrode 112, and secondary signal line 122 only can be connected to one of them tip of those camber claw-like electrodes in the second induction electrode 112.By flexible connected mode between aforementioned induction electrode pair and first group of signal wire, the touch electrode structure of this case is allowed to be applicable to various application scenario.
In the embodiment shown in Figure 2, when the finger of user or other touch object are seated in the first covering of the fan 119, the self-capacitance value that the first induction electrode 111 and the second induction electrode 112 sense will be caused to produce change respectively, and through the electric connection of the first signal wire 121 and secondary signal line 122 in signal line group 12, just can utilize and sense corresponding capacitance with the controller that signal wire is electrically connected (this figure is not shown).Size for two capacitances compares, just can estimate finger position and be positioned at relative angle angle value on arcuate sectors, such as the total angle of covering of the fan is 90 degree (pi/2s) at present, through for capacitance ratio measured on the first induction electrode 111 and the second induction electrode 112, just can estimate out the angle value that is less than 90 degree (pi/2s), and then obtain the angle in polar coordinates.Details herein can with reference to detailed description below.
And the gap that above-mentioned many camber lines 1101 ~ 1107 are formed, main object increases the resolution that interpretation goes out angle, so in resolution acceptable situation or when reducing at the central angle of covering of the fan, also the quantity of camber line can be selected to reduce, even be reduced on each covering of the fan and only have one, example such as shown in Fig. 3, can only come with the single camber line 33 being extended to this second point 32 by 1: 31 of covering of the fan 3 edge.That is, the number of the camber claw-like electrode in each induction electrode of those induction electrode centerings can have different designs in response to applied occasion, and each induction electrode can have one or more camber claw-like electrode.And from then on figure is observed, this figure is by shown in figure tetra-, the shape formed after the rectangular bend be combined into by two trapezoidal electrodes 41,42.And utilizing the electrode of figure tetra-to configure, to calculate positional information be prior art, therefore repeat no more.And the derivation simplified is as follows: mainly utilize the geometric relationship of two trapezoidal electrodes and the ratio of induced electricity capacitance, and then list following three simultaneous equationss:
(x-a)/(b-a)=(Y-y)/Y, wherein (x, y) represent the two-dimensional coordinate of touch points, a and b represent respectively trapezoidal on go to the bottom, X and Y is then the length of rectangle and wide;
X/ (a+b)=L/ (U+L), wherein L represents the capacitive sensing amount about trapezoidal electrode 41 sensed, and U represents the capacitive sensing amount about trapezoidal electrode 42 measured;
R=(b/a), wherein R represents the ratio of a and b;
And after rectangle converts covering of the fan to, available (π r)/n replaces by Y, so (x-a)/(b-a)=((π r)/n-y)/(π r)/n, wherein n is round halved number, and r is then the mean value of this covering of the fan outer shroud circular diameter and inner ring circular diameter.And can be simplified by above-mentioned formula and y=((RU-L)/(R-1) (U+L)) ((π r)/n), x also can utilize similar method to estimate, therefore utilize x, y value in Fig. 3, will the angle θ in polar coordinates needed for this case be pushed away to obtain.
Refer to Fig. 5 again, its be this case develop out the second embodiment schematic diagram about touch electrode structure, difference between its from the first embodiment is round halved number, and some is different, because the area of inner ring district covering of the fan 51 is less, therefore only inner ring is distinguished into quarter (n=4), but when the outer zone larger to area, for can resolution be maintained, this case is just divided into eight parts of outer zone covering of the fans 52, namely n=8, thus, the arc length of each electrode can not be long and cause locating inaccurate situation and occur.By parity of reasoning, if large-area touch-control border circular areas needs to realize, also the covering of the fan of outer shroud can be divided into more polylith again, therefore when and the distance in this first covering of the fan distance center of circle is less than the distance in this second covering of the fan distance center of circle, second covering of the fan can be divided into more part, make the arc angle of this first covering of the fan be greater than the arc angle of this second covering of the fan.This type of change is quite polynary, but neither from mentioned above principle, therefore do not repeat them here.To be provided with a single circular electrodes 59 as circle centre position, it may be defined to a button or preferred coordinate, can play the part of the role of acknowledgement key in touch pad, or whether these preferred coordinate of identification are touched.
This case is applied to the function block schematic diagram of contactor control device by Fig. 6 system, first, multiple touch-control sensing electrodes 60 that this case means complete can be built in any round by cloth, in the shape such as oval or fan-shaped, and be just drive singal sent to these touch-control sensing electrodes 60 every a bit of time and measure the induced electricity capacitance of each induction electrode 60 with the controller 62 that many signal line 61 that multiple touch-control sensing electrode 60 extends respectively are electrically connected, and these induced electricity capacitances are sent to the position computing module 63 of rear end, and then the computing carrying out similar aforesaid equation estimates out the polar coordinate position data of finger touch points, and then the two-dimensional coordinate after the polar coordinate position data obtained or conversion is passed to Portable/Wearable device 64 and uses.
In sum, this case can solve the disappearance that known touch-control sensing electrode effectively cannot be converted to the non-rectangle touch-control areas such as circle, ellipse or fan, therefore can be widely used in the changeable Wearable device of moulding or portable equipment, but also goodish positioning resolution can be maintained.In addition, this case must be appointed by person familiar with the technology and executed craftsman and to think and for modifying as all, so neither de-if attached claim institute is for Protector.
