Embodiment
Representative embodiments described herein relates to permission object's position is carried out exactly determined sensor array configuration.The sensor array configuration can be used the sensor of a plurality of different lengths, and these sensors have staggered starting position and end position.The starting position and the end position of the sensor by making different length are staggered, and the sensor that the required use of accurate positional information is provided in the given area still less.In addition, because can use still less sensor, thus can increase the size of each sensor in this zone, to improve the signal to noise ratio (S/N ratio) of the sensor in the array.
In following description of the preferred embodiments, with reference to the accompanying drawing that constitutes the application's part.Should be understood that under the situation of the scope that does not break away from preferred implementation, can use other embodiments and can carry out structural change.In addition, below description has comprised the example that comprises capacitive sensor.Be understood that to relate to the sensor that the capacitive transducer part also can refer to other types, include, without being limited to resistance sensing, surface acoustic wave sensing, pressure sensing (for example foil gauge), optical sensing, capacitance sensing etc.In addition, though touch pad is described to utilize the equipment of described sensor configuration, be understood that other sensing equipments (for example touch-screen) also can utilize these sensor configuration.
Fig. 2 (a) illustrates an example of capacitance sensing line.In Fig. 2 (a), circle 202 fingers that illustrate as object, the position of this object just is determined.In order to improve the degree of accuracy that positions with capacitive transducer 204, finger 202 once can cover more than a sensor 204.If finger once only covers a sensor, then only can detect on sensor, to exist and point 202.Therefore, can only say that finger is positioned at certain position within the defined zone of sensor fully, and can't more accurately judge the position of finger 202.
If finger covers more than a sensor, then can determine to cover the ratio of each sensor.For example, if finger 50 percent just be covered with each sensor, know that then finger is on the straight line between these sensors.If 25 percent of finger is just covering a sensor and 75 percent and just covering contiguous sensor, the more major part that then can know finger is positioned on the sensor that obtains high scale more.This is the reason with zigzag sensor 204 that is provided with shown in Fig. 2 (a).Serrate can more often be positioned on two sensors 204 finger 202 under the situation that does not make sensor become littler.
Fig. 2 (b) illustrates following example, and wherein bar shaped sensor 208 is divided into independent sensing section 206, and each approximately is a half-size scale of finger for these sensing sections.The size that reduces sensor can be positioned on a plurality of sensing sections finger simultaneously.But, reduce size the signal to noise ratio (S/N ratio) of the sensor in the array reduced.Therefore, size that can balance sensor is to deal with these problems.
In the example shown in Fig. 2 (b), two sensors 206 are covered by a finger 202.Can measure the number percent that two sensors are capped, to determine which position of finger between two sensors.This is another example of following method, and described method comprises the steps: big bar shaped sensor is divided into a plurality of sensing sections, reads all sensing sections, determines that also which section just is being activated with the location finger position.
In Fig. 2 (a) and 2 (b), the axle 200 that will measure is divided into eight section 204 and 206 along this axle, so that detect moving along this.Can detect has finger 202 on two sensing sections 204 or 206, and can measure its ratio and determine finger 202 is positioned at along which position of the axle 200 that will measure.The method of this definite finger position can be called as the proportion measurement technology.
Fig. 3 (a) and 3 (b) illustrate other examples of measuring along the position of axle 300 the object that will measure, and axle 300 extends to the length of a series of sensing zones 302.Fig. 3 (a) illustrates the example with five horizontal sensing zones capable 302, and each is divided into two sensing sections 304 this five horizontal sensing zones capable 302.Each sensing zone capable 302 comprises interruption 306, and interruption position is all different for each row 302.Except some section 304 was removed, Fig. 3 (b) and Fig. 3 (a) were similar.
Form contrast with Fig. 2 (a) and 2 (b), Fig. 3 (a) is not by the single sensor bar that disconnects along the axle that will measure.As an alternative, it is capable 302 that Fig. 3 (a) has five sensing zones, and each in these five sensing zones capable 302 is all along diverse location 306 places of the axle 300 that will measure separately.Sensing zone capable 302 is enough narrow and enough approaching, makes a finger 202 all to cover them simultaneously.Sensing zone capable 302 is also enough narrow, if make finger touch a sensing section 304 in the delegation, then it also will touch another sensing section 304 of closing in the row.
Therefore, the width of sensor can be selected as the diameter less than the object that will determine the position, for example less than the general diameter of pointing.In addition, the length of one or more sensors also can be selected as the diameter greater than the object that will determine the position.
In Fig. 3 (a), the top row in the sensing zone capable 302 comprises two sensing sections 302, promptly the left side than short pass sense section and right side than long pass sense section.Finger 202 covers long sensing section.In the sensing zone capable 302 second row comprise the right side than short pass sense section and left side than long pass sense section.Finger 202 covers short sensing section.The third line in the sensing zone capable 302 comprise the left side than short pass sense section and right side than long pass sense section.Finger 202 covers long sensing section.Fourth line in the sensing zone capable 302 comprise the right side than short pass sense section and left side than long pass sense section.Finger 202 covers long sensing section.Or the like.
In Fig. 3 (a), because the layout of sensor array is known, so can be positioned at the position of determining finger 202 on aforesaid which sensing section 304 by determining finger.Particularly, have only such position on the axle 300 that will measure: finger 202 can cover previously described that a series of segments 304.According to the number and the position of the interruption in the sensing zone 306, the usage ratio measuring technique more accurately determines the position of finger 202 in addition.
In the example shown in Fig. 3 (b),, remove a sensing section 304 every a sensing section 304 in an alternating manner on left side and right side.This distance that is meaning between sensing section 304 and the proximity sense section 304 will change along with the length of sensing section.
As mentioned above, because size, narrow degree and the position of row, a finger 202 can once cover all five level bands capable 302.Therefore, can determine to point 202 position by considering the residue sensing section in each the sensing row 302 among Fig. 3 (b).
In addition, if point 202 not on concrete sensing section 304, can judge that then finger 202 may be present in the zone that does not have the sensing section.For example, in Fig. 3 (b), finger 202 is detected as on the sensing section 304 that is arranged in the first and the 3rd sensing row 302, but not on the sensing section 304 of the second sensing row 302.Therefore, can determine to point 202 also is arranged on the rightward space of second row 302 of sensing section.Can similarly analyze each horizontal line 302.In Fig. 3 (b), diagram has only five sensing sections 304 in the zone, and this contrasts with eight sensing sections, 304 formation shown in the same area of Fig. 2 (a) and 2 (b).Therefore example shown in Fig. 3 (b) can make the number of sensing section 304 be reduced.
Fig. 4 illustrates following example, and wherein the structure shown in Fig. 3 (a) is by extends perpendicular.In Fig. 4, can measure the upright position of finger according to the method for describing in conjunction with Fig. 2 (a) along the Z-axis 406 that will measure.More specifically, each sensing row 402 can serve as along the sensor of following capacitance sensing line, and described capacitance sensing line extends along the Z-axis 406 that will measure.Because sensing row 402 is very thin, so a large amount of sensing row 402 are arranged in the unit length of the Z-axis 406 that will measure.According to the method for describing in conjunction with Fig. 2 (a), provide like this along the high-resolution position sensing of the Z-axis 406 that will measure.
Because along the interrupt pattern in the sensing section 404 of the transverse axis 408 that will measure, describe in conjunction with Fig. 3 (a), be used for can being used to measure along the transverse axis 408 that will measure along axle 300 measuring techniques of measuring that will measure.Therefore, same group of sensing section 404 can be used to determine that finger 202 is along both positions of the Z-axis 406 that will measure and the transverse axis that will measure 408.
The additive method of measuring along two axles can utilize that small-sized side's sensor (for example being finger one half-size scale) forms than macrolattice, also can utilize two-layer sensor, for example the horizontal group of the orthogonal sets of substrate front side and substrate back.In these methods each all utilizes the measuring technique of describing in conjunction with Fig. 2 (a) to measure along vertical and transverse axis.
Fig. 5 illustrates following example, and wherein the structure shown in Fig. 3 (b) is by extends perpendicular.In the example depicted in fig. 5, half that can use number of sensors shown in Figure 4 determined the horizontal and vertical position of finger 202.
Particularly, the same with Fig. 4, each sensing row 502 can serve as along the sensor of following capacitance sensing line, and described capacitance sensing line extends along the Z-axis 506 that will measure.Because sensing row 502 is very thin, so a large amount of sensing row 502 are arranged in the unit length of the Z-axis 506 that will measure.According to the method for describing in conjunction with Fig. 2 (a), can provide like this along the high-resolution position sensing of the Z-axis 506 that will measure.Be arranged on the interstitial site 510 of sensing row if point 202, then can whether be determined this situation by determining the sensing section that is positioned at 510 above and belows, gap by finger 202 activation.Not only be positioned at 510 tops, gap but also be positioned at its below if point 202, then it also is positioned on the gap 510.
In addition, because along the interrupt pattern in the sensing section 504 of the transverse axis 508 that will measure, therefore axle 300 measuring techniques of describing in conjunction with Fig. 3 (b) of measuring that are used for will measuring on the edge can be used to measure along the transverse axis 508 that will measure.Therefore, same group of sensing section 504 can be used to determine that finger 202 is along the two position of the Z-axis 506 that will measure and the transverse axis that will measure 508.
The notion that the sensor that utilization does not line up interrupts reducing the used number of sensors of position probing is not limited to horizontal bar or level band.Identical notion can be used to polar coordinate model or two dimension or other three-dimensional patterns.For example, this notion can be detected inside at least a in the following shape or outside by corresponding to: annular, cylindricality, taper shape, truncated cone shape (clipping most advanced and sophisticated circular cone), sphere, semisphere, part sphere, perhaps various other geometric configuratioies.
In the polar coordinates configuration, a plurality of sensor ring can be used to use polar coordinates to determine the position of finger.For example, sensor placement can comprise the sensor concentric ring.Can determine then to point just cover which ring, around the angle of this ring, and can the usage ratio measuring technique determine two positions between encircling.
But, if sensor is arranged that in the concentric ring mode then along with moving towards the center of circle, the size of wedge shape sensing section can reduce.Along with each sensing section becomes littler and sensitive zones reduces, each sensor the semaphore that can produce also can reduce (promptly based on making finger be positioned at that the capacitive reading of gained reduces on the sensor).Along with semaphore becomes littler, it is lower that signal to noise ratio (S/N ratio) also becomes.Therefore the sensitive zones of the sensing section in the inner loop of this layout can have low signal to noise ratio (S/N ratio), is low to moderate them and can't accurately measures finger position.
Fig. 6 illustrates an example of the another kind of sensor configuration of circular pattern, and it can be used to utilize section still less to come accurately to determine the polar coordinates position.Example shown in Figure 6 can be considered the polar coordinates form of expression of example shown in Figure 5.In Fig. 6, the Z-axis that will measure among Fig. 5 is corresponding to the angle θ around circle.In Fig. 6, the transverse axis that will measure among Fig. 5 is corresponding to the radius r or the amplitude (if regarding the vector that originates in the center of circle as) in the distance center of circle.In order to be easy to explanation, with respect to the number of sensing section 504 shown in Figure 5, sensing section 604 shown in Figure 6 and 606 number are reduced.
In Fig. 6, some sensing section 606 extends to the center of sensor array 600, and some sensing section 604 does not extend to the center of sensor array 600.Sensing element 604 and 606 combination can be used to accurately determine to be positioned at the polar coordinates position of the object (being finger 202 under this situation) on the sensor array 600.As long as the width of sensing section is less than the width of finger 202, finger 202 once will cover more than a sensor 604 and 606.
Can use this configuration to determine the angle θ of finger 202.Because section 604 and 606 is arranged in different angles θ on the circle, so can determine the angle θ of finger 202 by the angle θ that determines finger 202 sensors that activated 604 and 606.
Also can use this configuration to determine the radial position of finger 202.Because the section of having only 606 extends to the center of sensor array 600, so if having only sensing section 606 to be activated, then point 202 and be positioned at following radius: this radius is less than the radius at section 604 places.If sensing section 604 also is activated except sensing section 606, then point 202 radius that are positioned at sensor 604 places.
Layout shown in Figure 6 has reduced the sensor number and allowed carries out accurate polar coordinate mode location to object.In addition, this configuration allows to use littler polar coordinates sensor array configuration.
In the another kind of embodiment of example shown in Figure 6, can produce the configuration of not being with the center.For example, it is shorter that Wedging is got, and makes them can not arrive the center.Allow another input equipment (for example button) is placed on the center of sensor array like this.
