     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to the field of mutual capacitive detecting electronic system, and more particularly, to a mutual capacitive detecting touch sensitive processing apparatus dealing with two sets of sensing electrodes and method thereof. 
     2. Description of the Prior Art 
     Touch screens/panels (thereinafter touch screens) have already been one of the main input/output devices of modern consumer electronics. Especially, a screen in big size to have the function of touch sensing is the trend of market currently. For providing the coordinate position(s) of external conductive object(s) approaching or approximating a touch screen, a traditional touch sensitive processing apparatus needs to sequentially provide a driving signal to each of multiple first electrodes being parallel to a first direction, and to perform sensing by multiple second electrodes being parallel to a second direction. When all the electrodes are successively scanned (or sensed) in a round, the touch sensitive processing apparatus just reports the coordinate position(s) of all approaching or approximating event(s). 
     However, people&#39;s finger and the stylus&#39;s size will not become bigger as the size of the touch screen. For keeping the same resolution of approximating event in the touch screen in small size, the touch screen in big size configures a lot of first electrodes to maintain the intervals between/among the electrodes. As far as the touch screen in big size is concerned, it takes a lot of time to perform sequential scanning or sensing in a round and thus resulting in the reporting rate of approximating event being too slow. Therefore, a kind of mechanism for speeding up the reporting rate of approximating event is required to let user(s) keep the same or even have better experience in using the touch screen in big size.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Some embodiments of the present invention are described in detail below. However, in addition to the descriptions given below, the present invention can be applicable to other embodiments, and the scope of the present invention is not limited by such, rather by the scope of the claims. Moreover, for better understanding and clarity of the description, some components in the drawings may not necessary be drawn to scale, in which some may be exaggerated relative to others, and irrelevant parts are omitted. Besides, between/among the steps shown in the flowcharts of the present invention, a/some step(s) irrelative to the present invention may be inserted. The present invention does not limit the executing order of the steps except for causal relationship. 
     Referring to  FIG.  1   , it shows an electronic device  100  according to an embodiment of the present invention. The electronic device  100  includes a touch screen  120 . The touch screen  120  includes multiple sensing electrodes  121  being parallel to each other and multiple driving electrodes  122  being parallel to each other. Multiple intersections are formed by these two kinds of electrodes. The electronic device  100  further includes a touch sensitive processing apparatus  130  configured to connect to each of the sensing electrodes  121  and the driving electrodes  122  mentioned above, and used to detect or sense an external conductive object  110  which approaches or approximates to the touch screen  120 . The electronic device  100  further includes a host  140  configured to connect to the touch sensitive processing apparatus  130 . 
     In some embodiments, the host  140  may be one or some processor(s) and memory/memories which perform an operation system for controlling the electronic device  100 . For example, such as Intel x86 instruction set processor performing Microsoft Windows system; Qualcomm ARM instruction set processor performing Google Android system; Apple A9 processor performing Apple iOS system, and so on. 
     In some embodiments, the touch sensitive processing apparatus  130  includes an embedded processor, for example, such as Intel i960 processor, 8051 processor, ARM Cortex M series of processors, ARM7, ARM9, etc. The processor embedded in the touch sensitive processing apparatus  130  may perform related touch sensitive instructions for controlling the electrical signals emitting and receiving by each of the first (or sensing) electrodes  121  and each of the second (driving) electrodes  122 , and then transmits the touch related information got from having been processed to the host  140 . 
     As shown in  FIG.  1   , the multiple driving electrodes  122  from the top to the bottom may be the second electrodes  122 A-K. The touch sensitive processing apparatus  130  drives in turn the multiple driving electrodes  122  to cover the whole touch screen  120 . When each of the driving electrodes  122  is driven, sensing operations on all the first (sensing) electrodes  121  are performed. The time for the traditional scanning or sensing in  FIG.  1    relates to the number of the second electrodes  122 . 
     In some embodiments, the touch sensitive processing apparatus  130  may divide the driving electrodes  122  into the groups for multi-round driving to cover the whole touch screen  120 . In some embodiments of N-round driving, each N driving electrodes being adjacent to each other is combined to be a set of driving electrode which send the driving signal at the same time. 
     For example, in the embodiment of 2-round driving, a first round and a second round are separately driven to cover the whole touch screen  120 . In the first round, the driving electrodes  122 A and  122 B are the first set, the driving electrodes  122 C and  122 D are the second set, etc. In the second round, the driving electrodes  122 B and  122 C are the first set, the driving electrodes  122 D and  122 E are the second set, and so on. 
     Referring to  FIG.  2   , it shows a timing for 2-round driving according to an embodiment of the present invention. As the embodiment shown in  FIG.  1   , the touch screen  120  includes the driving electrodes  122 A-K arranged in order. In the first-round driving, the driving signal is firstly provided to the driving electrodes  122 A and  122 B at the same time, next the driving signal is provided to the driving electrodes  122 C and  122 B all at once, and so on. Until the last driving electrode  122 K, the touch sensitive processing apparatus  130  singly provides the driving signal to the driving electrode  122 K since there is no driving electrode to be made a pair with it. Because of driving single electrode only, the touch sensitive processing apparatus  130  may direct to and adjust waveform, voltage, strength of the driving signal, driving duration, and timing of driving. Furthermore, it may also direct to and adjust detecting duration, timing of detecting, time difference between the sensing timing and driving timing, resistance value of variable resistor of the sensing circuit, and gain value of amplifier of the sensing circuit of each sensing electrode  121 . These make the sensing strengths of a single driving electrode with regard to two driving electrodes are equivalent. The touch sensitive processing apparatus  130  may report the host  140  after the first-round sensing. Compared to the traditional one, the first-round touch sensing may save about half the time. 
     Next, to the second round, the touch sensitive processing apparatus  130  singly provides the driving signal to the driving electrode  122 A since there is no driving electrode to be made a pair with it. Because of driving single electrode only, the touch sensitive processing apparatus  130  may direct to and adjust the time, the strength, etc., of the driving signal. Furthermore, it may also direct to and adjust the time duration of sensing, the time difference between sensing timing and driving timing, and/or the gain value of sensing circuit of each sensing electrode  121 . These make the sensing strengths of single driving electrode and of two driving electrodes are equivalent. Then, the driving signal is provided to the driving electrodes  122 B and  122 C simultaneously, next the driving signal is provided to the driving electrodes  122 D and  122 E concurrently, and so on, until the last set of driving electrodes  122 J and  122 K. The touch sensitive processing apparatus  130  may report the host  140  after the second-round sensing. Compared to the traditional one, the second-round touch sensing may save about half the time. 
     Because two electrodes  122  are driven simultaneously, the sensed signal uses the central position of the two driving electrodes  122  as a base for addition. Therefore, to a motionless approximating object, its coordinate positions calculated from the first-round sensing and the second-round sensing are not the same, that is, moving up and down at two coordinate points. The host  140  may direct to fix this status by averaging the coordinate positions respectively got from the approximating event in the first-round and the approximating event in the second-round. Or the host  140  may average the coordinate positions got from the latest two approximating events to get the coordinate closer to real approximating position. 
     In the abovementioned embodiment, the host  140  selectively averages the approximating events got from the latest two rounds. The host  140  does not know that the approximating object has a bigger effect in the first-round sensing or the second-round sensing, so it seems the effects of the approximating object in the two rounds&#39; sensing are equivalent. For example, an approximating object is quite close to the driving electrode  122 D but it is between the driving electrodes  122 C and  122 D. In the first-round scanning (or sensing) to the driving electrodes  122 C and  122 D, a first approximating event and a related first coordinate are got. In the second-round scanning (or sensing) to the driving electrodes  122 D and  122 E, a second approximating event and a related second coordinate are got. Supposedly, the sensing quantity of the first approximating event should be bigger than the sensing quantity of the second approximating event because the position of the approximating object is between the driving electrodes  122 C and  122 D. Since the touch sensitive processing apparatus  130  report the information to the host  140  which only includes the first coordinate and the second coordinate but does not include the sensing quantities of the first approximating event and the second approximating event, the method that the host  140  averages the first coordinate and the second coordinate is not precise yet. 
     Referring to  FIG.  3   , it shows a timing for 2-round driving according to an embodiment of the present invention. The difference to the embodiment of  FIG.  2    is that the touch sensitive processing apparatus  130  will perform a first-round sensing and a second-round sensing firstly to get the first-round&#39;s approximating event and related coordinate and the second-round&#39;s approximating event and related coordinate, correspondingly. Next, the touch sensitive processing apparatus  130  will perform weighted operations to the first-round coordinate and the second-round coordinate according to the sensing quantity of the first-round approximating event and the sensing quantity of the second-round approximating event, respectively, to get the more precise position. 
     Therefore, in  FIG.  3   , the touch sensitive processing apparatus  130  reports the coordinate to the host  140  according to the latest two rounds&#39; information except that the touch sensitive processing apparatus  130  does not report to the host  140  at the first-round sensing. The reporting rate is double to the traditional one except that the first reporting rate is about equal to the traditional one. 
     In the embodiments shown in  FIG.  2    and  FIG.  3   , the sets of the driving electrodes  122  are sequentially driven from the top to the bottom. However, this sequential driving method may cause a fixed frequency EMI with other parts inside the electronic apparatus  100  or other electronic apparatuses around the electronic apparatus  100 . Therefore, in another embodiment, the sets of the driving electrodes  122  are driven in random in order to reduce EMIs in some certain frequencies. 
     Although the reporting rates of  FIGS.  2  and  3    is double to the traditional one, there are other sensing modes&#39; reporting rate may be higher than double traditional one. Referring to  FIG.  4   , it shows an accelerating sensing according to an embodiment of the present invention. In  FIG.  4   , a whole screen driving is performed firstly, that is, the driving signal is simultaneously provided to the driving electrodes  122 A-K. The touch sensitive processing apparatus  130  may determine whether an approximating object exists according to the sensing results from all sensing electrodes  121 . If not, the touch sensitive processing apparatus  130  may report no approximating object to the host  140 . In other words, when there is no any approximating object, using the whole screen driving would have the fastest reporting rate. 
     As shown in  FIG.  4   , when the touch sensitive processing apparatus  130  determines the approximating object exists, it may sequentially provide the driving signal to the driving electrodes  122 A-K. When the touch sensitive processing apparatus  130  determines approximating objects near the driving electrodes  122 B and  122 H, it may report to the host  140 . Then, several times of accelerating sensings may be performed, that is, only providing the driving signal to the driving electrodes  122 B and  122 H to perform sensing, and reporting to the host  140 . 
     It can be imaged that if the quantity of approximating object(s) is smaller, the time spent by the accelerating sensing is less. The reporting rate is reporting number divided by the total time of one whole screening sensing and several times of accelerating sensing. When the reporting rate is higher than double traditional one, this sensing may be adapted. However, when the quantity of approximating objects is bigger, making the reporting rate less than half the traditional one, the sensing ways of  FIGS.  2  and  3    may be switched to. 
     Referring to  FIG.  5   , it shows a switching of sensing way according to an embodiment of the present invention.  FIG.  5    is the same as  FIG.  4    at the beginning, performing the whole screen driving firstly, that is, providing the driving signal to the driving electrodes  122 A-K simultaneously. The touch sensitive processing apparatus  130  may determine whether an approximating object exists according to the sensing results from all sensing electrodes  121 . When the touch sensitive processing apparatus  130  determines the approximating object exists, it may sequentially provide the driving signal to the driving electrodes  122 A-K. When the quantity of approximating objects is bigger and making the reporting rate less than half the traditional one, the touch sensitive processing apparatus  130 , for example, may switches to the sensing ways of  FIGS.  2  and  3    after reporting to the host  140 . As shown in  FIG.  5   , the touch sensitive processing apparatus  130  switches to the sensing way of  FIG.  2   . 
     Conversely, when the embodiments of  FIGS.  2  and  3    are implemented, and if the touch sensitive processing apparatus  130  determines the quantity of the approximating objects is smaller, and the reporting rate by using the embodiment shown in  FIG.  4    (a whole screen and sequential driving and several times of accelerating sensing) is faster, the sensing way shown in  FIG.  2    or  FIG.  3    may switch to the sensing way shown in  FIG.  4   . 
     In a variation of the embodiment in  FIG.  5   , when a whole screen driving and detecting is performing and an approaching object is determined by the touch sensitive processing apparatus  130  according to the sensing results of all sensing electrodes  121 , the sequential driving and detecting shown in the embodiment of  FIG.  5    may be omitted and a multiple round detecting is performed directly. By doing so, because of omitting the time of sequential driving and detecting, the first reporting time will faster than that of the embodiment in  FIG.  5   . 
     To sum up, the present application provides several sensing ways having faster reporting rate than the traditional one. Moreover, according to the quantity of the approximating object(s), the present application may provide the determining conditions for switching the sensing ways. The present application may let the host  140  receive more approximating event reports in one unit of time to make user(s) have better touch sensitive experience, especially in using the touch sensitive screen in big size. 
     Referring to  FIG.  6   , it shows an electronic system  600  according to an embodiment of the present invention. The electronic system  600  includes a touch panel or screen  620  (thereinafter touch screen). The touch screen  620  includes multiple driving electrodes  122  being parallel to each other, multiple upper half sensing electrodes  650  being parallel to each other, and multiple lower half sensing electrodes  660  being parallel to each other. Multiple intersections are formed on the upper half of the touch screen  620  by the multiple driving electrodes  122  and multiple upper half sensing electrodes  650 . Multiple intersections are formed on the lower half of the touch screen  620  by the multiple driving electrodes  122  and multiple lower half sensing electrodes  660 . The electronic device  600  further includes a touch sensitive processing apparatus  630  configured to connect to each of the upper half sensing electrodes  650 , the lower half sensing electrodes  660 , and the driving electrodes  122  mentioned above, and used to detect or sense an external conductive object  110  which approaches or approximates to the touch screen  620 . The upper half sensing electrodes  650  connect to the touch sensitive processing apparatus  630  from the upper half side of the touch screen  620 . The lower half sensing electrodes  660  connect to the touch sensitive processing apparatus  630  from the lower half side of the touch screen  620 . The electronic device  600  further includes a host  140  configured to connect to the touch sensitive processing apparatus  630 . 
     In some embodiments, the touch sensitive processing apparatus  230  includes an embedded processor, for example, such as Intel i960 processor, 8051 processor, ARM Cortex M series of processors, ARM7, ARM9, etc. The processor embedded in the touch sensitive processing apparatus  230  may perform related touch sensitive instructions for controlling the electrical signals emitting and receiving by each of the electrodes  122 ,  650 , and  660 , and then transmits the touch related information got from having been processed to the host  140 . 
     As shown in the embodiment of  FIG.  6   , since the number of the driving electrodes  122  is eleven in an odd number, the touch screen  620  may divided into the upper and lower halves from the interval between the sixth and the seventh driving electrodes  122 . The upper half compared to the lower half has one more driving electrode. When the number of the driving electrodes  122  is an even number, the upper and lower halves of the touch screen  620  may have the same number of the driving electrodes  122 . 
     Moreover, as shown in the embodiment of  FIG.  6   , the number and the positions of the upper half sensing electrodes  650  and the lower half sensing electrodes  660  are corresponded. Each of the upper half sensing electrodes  650  correspond to one of the lower half sensing electrodes  660  so that the position of the external conductive object  110  can be calculated by the touch sensitive processing apparatus  630 . 
     Referring to  FIG.  7   , it shows mutual-capacitance sensing ways according to the embodiments of the present invention. On the left side of  FIG.  7   , a traditional sensing way  710  for the traditional touch sensitive processing apparatus  130  to the touch screen  120  is illustrated and is adaptive to the embodiment of  FIG.  1   . The traditional touch sensitive processing apparatus  130  transmits in turn the driving signal to the driving electrodes  122 A-K and performs sensing by the sensing electrodes  121 . After each of the driving electrodes  122  is driven, the traditional touch sensitive processing apparatus  130  sends one approximating even report to the host  140 . 
       FIG.  7    also shows three accelerating sensing ways  720 ,  730 , and  740  adaptive to the embodiment of  FIG.  6   . At the beginning of the accelerating sensing ways  720 , the touch sensitive processing apparatus  630  simultaneously provides the driving signal to two driving electrodes  122 A and  122 G respectively belonging to the upper and the lower halves, that is, the top driving electrodes  122  in the upper and the lower halves, respectively. At the same time, the touch sensitive processing apparatus  630  also respectively receives the driving signals sensed by the upper half sensing electrodes  650  and the lower half sensing electrodes  660 . Next, the touch sensitive processing apparatus  630  sequentially performs the abovementioned steps to provide the driving signal to two driving electrodes respectively belonging to the upper and the lower halves. In the last round, the driving electrodes belonging to the lower half are driven completely, thus only the driving electrode  122 F in the upper half needs to be driven and only the driving signal sensed by the sensing electrode  650  in the upper half needs to be received. After this step, the touch sensitive processing apparatus  630  sends one approximating event report to the host  140 . 
     Obviously, the accelerating sensing way  720  is faster than the traditional sensing way  710  about double in time, that is, for example, the reporting rate of approximating event is faster about twice. The cost is to provide double sensing circuits to simultaneously respectively connect to the multiple upper half sensing electrodes  650  being parallel to each other and the multiple lower half sensing electrodes  660  being parallel to each other. 
     Similarly, the difference between the accelerating sensing ways  730  and  720  is that the driving direction for the touch sensitive processing apparatus  630  in the lower half is from the bottom to the top. This is also different to the driving direction in the upper half being from the top to the bottom. Also, the accelerating sensing way  730  is faster than the traditional sensing way  710  about double in time, that is, for example, the reporting rate of approximating event is faster about twice. 
     The accelerating sensing ways  740  is alike those shown in  FIG.  2    and  FIG.  3   , that is, grouping the upper and lower halves of driving electrodes  122 . As shown in  FIG.  7   , the six driving electrodes  122 A-F in upper half are divided into three groups, the driving electrodes  122 G-K in lower half are also divided into three groups, but the driving electrode  122 K is the only one in its group. The accelerating sensing ways  740  may be the same as those shown in  FIG.  2   , performing two-round sensing ways, respectively. In the first round sensing of upper half of the touch screen, the six driving electrodes  122 A-F are driven by group in turn. At the same time, in the first round sensing of lower half of the touch screen, the five driving electrodes  122 G-K are driven by group in turn, that is, driving a set of driving electrodes  122 G-H firstly, then driving another set of driving electrodes  122 I-J, and finally driving the single driving electrode  122 K. After the first round sensing is finished, reporting the approaching object detected by the upper half and the lower half of the touch screen may be respectively performed. In the second round of the upper half touch screen, since the driving electrodes of the upper half touch screen are even, the same order for driving the six driving electrodes  122 A-F by group in turn can be adapted. But in the second round of the lower half touch screen, since the driving electrodes of the lower half touch screen are odd, the single driving electrode  122 G may be driven firstly, next a set of driving electrode, and finally another set of the driving electrodes  122 J-K. After the second round sensing is finished, reporting the approaching object detected by the upper half and the lower half of the touch screen may be respectively performed. 
     The accelerating sensing ways  740  maybe also the same as the method shown in  FIG.  2   . After performing first two rounds of sensing, the coordinate according to this two rounds&#39; sensing information is just reported to the host  140 . Except for the rate of the first reporting being equal to the rate of traditional reporting, the follow-up rates of reporting are two times of the rate of traditional reporting. 
     Similarly, the upper half and the lower half touch screen in  FIG.  6    can be respectively seemed to independent touch screens adaptive to the implementations of  FIG.  4    and  FIG.  5   . That is, half screen driving and detecting is performed to the upper half and the lower half touch screen respectively. When an approaching object is detected by the half touch screen, the sequence driving and detecting is just performed on the half touch screen and next the accelerating sensing is performed. Or, the half screen driving and detecting is firstly performed to the upper half and the lower half touch screen respectively. When an approaching object is detected by the half touch screen, the multiple round sensing is just performed on the half touch screen. 
     The present invention may have other driving ways. For example, the touch sensitive processing apparatus  630  may singly provide the driving signal to the driving electrode  122 F firstly. Next, the touch sensitive processing apparatus  630  provides the driving signal to each of the driving electrodes  122  from the bottom to the top in the upper half and from the top to the bottom in the lower half. 
     In some embodiments, to protect the electronic device  600  from regular electromagnetic interference (EMI) resulting from sequential driving direction, the touch sensitive processing apparatus  630  may even use a random way to finish the driving and sensing in the upper and the lower halves. The sensing way in each round may use a random way, e.g., the same random way may be used in the upper and the lower halves, or the different random way may be used in the upper and the lower halves. Even a certain half uses a random way to perform sensing and the other uses a sequential way to perform sensing. The object is to avoid the regular EMI generated by the touch screen  620 , to lower the EMI effect to other equipment in the electronic device  600 , such as the wireless communication interface or screen, or to reduce the EMI to other equipment beside the electronic device  600 . 
     In the embodiment of  FIG.  6   , the driving electrodes  122  are parallel to the direction of the horizontal axis which the touch screen  620  refreshes pixels, and thus the touch screen  620  is divided into two parts in the upper and the lower halves. In some embodiments, the touch screen  620  may be divided into two parts in the left and the right halves. The driving electrodes  122  are vertical to the direction of the horizontal axis which the touch screen  620  refreshes pixels. Multiple left half sensing electrodes being parallel to each other connect to the touch sensitive processing apparatus  630  from the left side of the touch screen  620 . Multiple right half sensing electrodes being parallel to each other connect to the touch sensitive processing apparatus  630  from the right side of the touch screen  620 . Except for the direction being changed, the sensing ways of the touch sensitive processing apparatus  630  may use the sensing ways according to the accelerating sensing ways  720  and  730  shown in  FIG.  7   , and the variations of various abovementioned sensing ways. 
     One of the advantages in using the upper and the lower halves shown in  FIG.  6    is that the driving electrodes  122  are parallel to the direction of pixel horizontal axis. When a certain driving electrode sends the driving signal and the pixel horizontal axis near the certain driving electrode just performs refreshing, the driving signals sensed by all the upper half sensing electrodes  650  or all the lower half sensing electrodes  660  and the pixel refreshing current are almost consistent. 
     Besides, in some in-cell type of touch sensitive liquid crystal display (LCD)  620 , the driving electrodes  122  may be used together with the common electrodes of the LCD. The advantage of this part may refer to USPA No. 2014/0071360.
