## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Application No. 61/911,018, filed on Dec. 3, 2013, the contents of which are incorporated herein by reference.


BACKGROUND
The present application relates to a touch panel device controlling method and a touch panel device, and particularly relates to a touch panel device controlling method and a touch panel device that can trigger a predetermined operation via touch communications connections.
According to the related art, Near Field Communication (NFC) can be regarded as a contactless identification and interaction technology, and can be used for performing short distance wireless communications between mobile devices, consumer electronic products, personal computers, and/or intelligent electronic devices through a method of near field magnetic coupling (e.g. using the frequency of 13.56 MHz). The users of NFC devices can intuitively exchange information and acquire contents and services with ease.
As the market for portable electronic devices such as mobile phones equipped with NFC functionalities has become mature, they can be used for supporting mobile payment or point of sale (POS) . However, as the NFC devices are designed to transmit and receive signals through magnetic coupling, it is typical to implement an inductive card reader or some components having similar functionalities in the aforementioned portable electronic devices such as the mobile phones mentioned above, which may cause the sizes of the portable electronic devices to be increased, and further cause the layouts, the structure arrangement, and the materials of components in the portable electronic devices such as the mobile phones to be limited.
Therefore, some touch communications technologies regarding touch panel devices (e.g. electronic device equipped with touch panels), such as those described in the U.S. Patent Application Publication No. 2011/0304583, the U.S. Patent Application Publication No. US 2013/0147760, the China Patent Application Publication No. CN 102916729 A, are proposed recently, where the touch panels and the driving integrated circuit (IC) in the touch panel devices can be used for performing communications and data transmission. For example, a conventional touch panel device may comprise a touch sensor. In addition, at least one portion of the touch sensor can be at least one portion of the touch panel in the conventional touch panel device, where the touch panel can be a touch panel that does not have the display functionality (e.g. a touch pad), or a touch panel that has the display functionality (e.g. a touch screen). The touch sensor may comprise multiple driving electrodes and sensing electrodes installed on substrates, such as the driving electrodes and the sensing electrodes for forming capacitor structures. At least one of the driving electrodes and the sensing electrodes can be used as transmitting electrodes, and at least one of the driving electrodes and the sensing electrodes can be used as receiving electrodes. Thus, the signals can be transmitted or received by using the electrodes and the driving IC in the conventional touch panel device, to realize touch communications based on electric fields, having no need to implement any inductive card reader or some components having similar functionalities in the conventional touch panel device, where this architecture can significantly reduce the size and save the costs, in comparison with the NFC technology.
Please refer to FIG. 1, which illustrates a diagram of touch communications between a first touch panel device 101 and a second touch panel device 102 according to the related art. As shown in FIG. 1, there are near field electric fields 103a and 103b between the first touch panel device 101 and the second touch panel device 102. It should be noted that each of the first touch panel device 101 and the second touch panel device 102 can have the functionalities of transmitting and receiving signals. Based on this touch communications technology, when the first touch panel device 101 transmits signals toward the second touch panel device 102, the communications medium used by the first touch panel device 101 is the electric field portion whose electric field direction is pointing toward the second touch panel device 102 (e.g. the near electric field 103a shown in FIG. 1). In addition, when the second touch panel device 102 transmits signals toward the first touch panel device 101, the communications medium used by the second touch panel device 102 is the electric field portion whose electric field direction is pointing toward the first touch panel device 101 (e.g. the near electric field 103b shown in FIG. 1). Please note that the X channels and the Y channels shown in FIG. 1 may represent the transmitting electrodes and receiving electrodes installed on substrates, such as the transmitting electrodes and the receiving electrodes for forming capacitor structures.

More particularly, the touch communications request signal generating unit 211 may be arranged to generate a touch communications request signal, and to transmit the touch communications request signal to the second touch panel device 102 through the transmitting electrodes of the first touch panel device 101. After the first touch panel device 101 receives a response signal responded by the second touch panel device 102, such as the response signal received through the receiving electrodes of the first touch panel device 101, the communications connection establishment unit 212 may establish a communications connection with the second touch panel device 102 (i.e. the communications connection between the first touch panel device 101 and the second touch panel device 102). After the communications connection establishment unit 212 establishes the communications connection, the first communications unit 213 may transmit communications information and/or data to the second touch panel device 102 through the transmitting electrodes of the first touch panel device 101.
The signal receiving system 202 may comprise a touch communications request signal responding unit 221, a communications connection establishment unit 222, and a second communications unit 223. More particularly, after receiving the touch communications request signal transmitted by the first touch panel device 101, such as the touch communications request signal received through the receiving electrodes of the second touch panel device 102, the touch communications request signal responding unit 221 may respond to the touch communications request signal with a response signal such as that mentioned above, and more particularly, may send the response signal to the first touch panel device 101 through the transmitting electrodes of the second touch panel device 102. After the touch communications request signal responding unit 221 responds to the touch communications request signal of the first touch panel device 101 with the response signal, the communications connection establishment unit 222 may establish the communications connection with the first touch panel device 101 (i.e. the communications connection between the first touch panel device 101 and the second touch panel device 102). After the communications connection establishment unit 222 establishes the communications connection, the second communications unit 223 may receive the communications information and/or data from the first touch panel device 101 through the receiving electrodes of the second touch panel device 102.
FIG. 3 illustrates a first touch panel 301 of the first touch panel device 101 shown in FIG. 1 and a second touch panel 302 of the second touch panel device 102 shown in FIG. 1 according to the related art. As shown in FIG. 3, each touch panel of the first touch panel 301 and the second touch panel 302 may comprise a touch sensor (not completely shown in FIG. 3). For example, the touch sensor of the first touch panel 301 may comprise a set of transmitting electrodes installed on at least one substrate of the first touch panel 301 (e.g. the transmitting electrode 311) for transmitting signals, and may comprise a set of receiving electrodes installed on at least one substrate of the first touch panel 301 (e.g. the receiving electrode 312) for receiving signals. In another example, the touch sensor of the second touch panel 302 may comprise a set of transmitting electrodes installed on at least one substrate of the second touch panel 302 (e.g. the transmitting electrode 321) for transmitting signals, and may comprise a set of receiving electrodes installed on at least one substrate of the second touch panel 302 (e.g. the receiving electrode 322) for receiving signals.

First, in Step S401, the touch communications request signal generating unit 211 of the first touch panel device 101 may generate a touch communications request signal such as that mentioned above, and transmit the touch communications request signal to the second touch panel device 102 through the transmitting electrode(s) of the first touch panel device 101. Afterward, in Step S402, the touch communications request signal responding unit 221 of the second touch panel device 102 may respond to the touch communications request signal with a response signal such as that mentioned above through the transmitting electrode(s) of the second touch panel device 102, and more particularly, send the response signal to the first touch panel device 101 through the transmitting electrode(s) of the second touch panel device 102. After the first touch panel device 101 receives the response signal responded by the second touch panel device 102, such as the response signal received through the receiving electrodes of the first touch panel device 101, in Step S403, the communications connection establishment unit 212 of the first touch panel device 101 and the communications connection establishment unit 222 of the second touch panel device 102 may establish a communications connection such as that mentioned above (i.e. the communications connection between the first touch panel device 101 and the second touch panel device 102). As a result, in Step S404, the first touch panel device 101 (more particularly, the first communications unit 213 therein) and the second touch panel device 102 (more particularly, the second communications unit 223 therein) may perform communications as shown in FIG. 4. For example, the first communications unit 213 of the first touch panel device 101 may transmit the communications information and/or data to the second touch panel device 102 through the transmitting electrodes of the first touch panel device 101, and the second communications unit 223 of the second touch panel device 102 may receive the communications information and/or data from the first touch panel device 101 through the receiving electrodes of the second touch panel device 102.

DETAILED DESCRIPTION
FIG. 5 is a schematic diagram illustrating the operation for a touch panel device controlling method according to one exemplary embodiment of the present application. A touch panel device may be any electronic device equipped with at least one touch panel, such as a mobile phone, a wearable device, a tablet, a laptop, a kiosk, a television, etc. The touch panel can be a touch panel that does not have the display functionality (e.g. a touch pad), or a touch panel that has the display functionality (e.g. a touch screen). As shown in FIG. 5, a touch communications connection sequence TCCS may be established between a first touch panel device C_a and at least one second touch panel devices Cb1, Cb2, . . . Cbn. Please note the second touch panel devices Cb1, Cb2, . . . Cbn can mean a single second touch panel device or mean more than one second touch panel devices. The touch communications connection sequence TCCS may include a plurality of touch communications connections TCC_1, TCC_2 . . . TCC_n. The touch communications connection can be established based on the steps illustrated in FIG. 1 and FIG. 4, but can be established via other steps as well. Then a predetermined operation may be performed by the first touch panel device C_a based on the touch communications connection sequence TCCS.
To establish touch communications connection, a first touch panel of a first touch panel device may be close to or in contact with a second touch panel of a second touch panel device. The first touch panel of the first touch panel device is close to or in contact with the second touch panel of the second touch panel device can mean that the distance between the first touch panel and the second touch panel is not larger than a predetermined distance. For example, if the predetermined distance is 2 cm, the first touch panel is close to or in contact with the second touch panel can mean that the distance between the first touch panel and the second touch panel is not larger than 2 cm. This is for illustrative purpose only, but not a limitation. The predetermined distance may vary with the touch panel, its driving IC, and the design of the electronic device, and may be greater, such as 5 cm, or may be less, such as 2 mm, and so on.
Further, a touch communications connection sequence recognition may be performed. For example, it may be determined that if the touch communications connection sequence TCCS follows a recognizing rule, to generate a determining result. Then the predetermined operation may be performed by the first touch panel device C_a based on the determining result. For example, if the touch communications connection sequence TCCS follows a recognizing rule, perform the predetermined operation of the first touch panel device. If not, do not perform the predetermined operation of the first touch panel device.
In one exemplary embodiment, performing a predetermined operation may include, but not limited to, controlling a device other than the second touch panel device (s), executing an application installed in the first touch panel device, etc. According to some exemplary embodiments, the operations of controlling the device other than the second touch panel device (s) may vary. For example, when a first touch communications connection sequence is established and follows a recognizing rule, a processing unit (not shown) may control the first touch panel device C_a to turn on a TV and to remotely control the TV to switch to a predetermined channel . In another example, when a second touch communications connection sequence is established and follows a recognizing rule, the processing unit may control the first touch panel device C_a to turn on an air condition system. In another example, when a third touch communications connection sequence is established and follows a recognizing rule, the processing unit may control the first touch panel device C_a to turn on an audio playback system and to remotely control the audio playback system to play a predetermined audio program. This is for illustrative purposes only, and is not meant to be a limitation of the present invention. According to some exemplary embodiments, the operations of executing the application may vary. For example, when a fourth touch communications connection sequence is established and follows a recognizing rule, the first touch panel device C_a may run an electronic mail (e-mail) application. In another example, when a fifth touch communications connection sequence is established and follows a recognizing rule, the first touch panel device C_a may run a web page browser application. In another example, when a sixth touch communications connection sequence is established and follows a recognizing rule, the first touch panel device C_a may run a ticket service application. This is for illustrative purposes only, and is not meant to be a limitation of the present invention.
The recognizing rule is a criterion for determining if the predetermined operation for the first touch panel device should be performed or not, and can be set corresponding to different situations. For example, the recognizing rule may include: an amount of the touch communications connections is not less than a predetermined touch communications connection number. For another example, if an amount of the second touch panel device is more than one, the recognizing rule may include: the touch communications connections are established in a predetermined order by the second touch panel devices. In one exemplary embodiment, the touch communications connection sequence mentioned above is established in a predetermined total time interval.
Alternatively, the recognizing rule may include: each time difference between each time point at which the touch communications connection is established is smaller than a predetermined connection time interval. The detail for each example of the recognizing rule will be described later. Please note the recognizing rule is not limited to include a single criterion. For example, the recognizing rule can include: an amount of the touch communications connections is not less than a predetermined touch communications connection number, and each time difference between each time point at which the touch communications connection is established is smaller than a predetermined connection time interval.
Each of FIG. 6 and FIG. 6A is a schematic diagram illustrating that touch communications connections are established between a first touch panel device and a second touch panel device, according to one exemplary embodiment of the present application. As shown in FIG.6, the touch communications connections TCC_1, TCC_2. . .TCC_n may be established between a first touch panel device C_a and the same one second touch panel device Cb1. The second touch panel device Cb1 may be close to or in contact with the first touch panel device C_a at a time point τ_1 thereby the touch communications connection TCC_1 is established. After the touch communications connection TCC_1 is established, the touch panel device C_b1 may leave after a time interval Δτ_1 passes. After that, the touch panel device C_b1 may be close to or in contact with the first touch panel device C_a at a time point τ_2 again thereby another touch communications connection TCC_2 is established. In another example, after the touch communications connection TCC_1 is established, the touch panel device C_b1 may leave. And after the time interval Δτ_1 passes, the touch panel device C_b1 may be close to or in contact with the first touch panel device C_a at the time point τ_2 again thereby another touch communications connection TCC_2 is established. By the similar way, the following touch communications connections TCC_3. . .TCC_n may be established.
As illustrated above, in one exemplary embodiment the recognizing rule may include: an amount of the touch communications connection is not less than a predetermined touch communications connection number. For example, assuming the predetermined touch communications connection number is 2, it will be determined that if the amount of the touch communications connections established between the first touch panel device C_a and the second touch panel device C_b1 is not less than 2; if the amount of the established touch communications connections is 4 and thus not less than 2, as shown in FIG. 6, the touch communications connection sequence is recognized. Assuming the predetermined touch communications connection number is 5, it will be determined that if the amount of the touch communications connections established between the first touch panel device C_a and the second touch panel device C_b1 is not less than 5; if the amount of the established touch communications connections is 4 and thus less than 5, as shown in FIG. 6, the touch communications connection sequence is not recognized. In one exemplary embodiment, it will also be determined that if the touch communications connection sequence is established in a predetermined total time interval T. That is, the touch communications connections should be established in the predetermined total time interval T, or the touch communications connection sequence is not recognized even the amount of the touch communications connections is not less than the predetermined touch communications connection number.
As illustrated above, in another exemplary embodiment the recognizing rule may include: each time difference between each time point at which the touch communications connection is established is smaller than a predetermined connection time interval. For example, the time differences (τ_2−τ_1), (τ_3−τ_2) . . . (τ_n−τ_n−1) are smaller than a predetermined connection time interval in the exemplary embodiment of FIG. 6.
FIG. 7 is a schematic diagram illustrating that touch communications connections are established between a first touch panel device and more than one second touch panel devices, according to one exemplary embodiment of the present application. The difference between the exemplary embodiments illustrated in FIG. 6 and FIG. 7 is that the touch communications connections in FIG. 6 are established between a first touch panel device and a single second touch panel device, while the touch communications connections in FIG. 7 are established between a first touch panel device and more than one second touch panel device C_b1, Cb2 . . .C_bn.
The recognizing rule applied to the exemplary embodiment in FIG. 6 can be applied to the exemplary embodiment in FIG. 7 as well. That is, the recognizing rule can include: an amount of the touch communications connections is not less than a predetermined touch communications connection number, and/or include: each time difference between each time point at which the touch communications connection is established is smaller than a predetermined connection time interval.
Besides, since different second touch panel devices are applied in the exemplary embodiment of FIG. 7, the recognizing rule can include: the touch communications connections are established in a predetermined order by the second touch panel devices. For example, assuming the predetermined order is C_b2-C_b3-C_b1 , it will be determined that if three touch communications connections are established sequentially between the first touch panel device C_a and the second touch panel device C_b2, the second touch panel device C_b3 and the second touch panel device C_b1 , or the touch communications connection sequence is not recognized. In another example, assuming the predetermined order is C_b5-C_b1-C_b3-C_b2-C_b6, it will be determined that if five touch communications connections are established sequentially between the first touch panel device C_a and the second touch panel device C_b5, the second touch panel device C_b1, the second touch panel device C_b3, the second touch panel device C_b2 and the second touch panel device C_b6, or the touch communications connection sequence is not recognized.
It will be appreciated that each of the second touch panel device in FIG. 7 is not limited to establish only one touch communications connection with the first touch panel device C_a. For example, the predetermined order can be C_b1-C_b2-C_b1, which requires the second touch panel device C_b1 to establish touch communications connection with the first touch panel device C_a twice, one before the second touch panel device C_b2 establishing connection and one after that. Additionally, please note, the order and the amount of the touch communications connections illustrated in FIG. 6 and FIG. 7 are only for example and do not mean to limit the scope of the present application. Besides, different recognizing rules, such as different predetermined touch communications connection numbers, different predetermined orders, etc., may correspond to the same or different predetermined operations to perform. For example, the first recognizing rule (e.g. not less than the number M of connections are established between the first touch panel device C_a and the second touch panel device C_b1 in a predetermined total time interval T) and the second recognizing rule (e.g. not less than the number N of connections are established between the first touch panel device C_a and the second touch panel device C_b1 in a predetermined total time interval T) may correspond to the same operation (e.g. control the first touch panel device C_a to turn on a TV and to remotely control the TV to switch to a predetermined channel) or different operations (e.g. respectively control the first touch panel device C_a to turn on a TV and to remotely control the TV to switch to a predetermined channel, and the first touch panel device C_a to run an electronic mail application). For another example, the first recognizing rule (e.g. not less than the number M of connections are established between the first touch panel device C_a and the second touch panel device C_b1 in a predetermined total time interval T) and the third recognizing rule (e.g. touch communications connections are established in the predetermined order C_b2-C_b1) may correspond to the same operation (e.g. control the first touch panel device C_a to turn on an audio playback system and to remotely control the audio playback system to play a predetermined audio program) or different operations (e.g. respectively control the first touch panel device C_a to run a web page browser application or a ticket service application).
FIG. 8 is a flow chart illustrating exemplary steps for a touch panel device controlling method according to one exemplary embodiment of the present application. As shown in FIG. 8, the touch panel device controlling method comprises:
Step 801
Start.
Step 803
The first touch panel device can be in a recognizing state. A touch communications connection sequence can be established and determined in such state. In one exemplary embodiment, the recognizing state is maintained for a predetermined total time interval (ex. T in FIG. 6 and FIG. 7).
Step 805
If a touch communications connection is to be established or established, determine if a time point that a touch communications connection established between the first touch panel device and a second touch panel device is in the predetermined total time interval. That is, determine if the time points τ_1, τ_2 . . . τ_n is in the predetermined total time interval T. If yes, proceed to step 807. If not, the process proceeds to step 809. This step may be performed by a processing unit of the first touch panel device, a processing unit of the second touch panel device, or both. Via such step, the touch communications connections out of the predetermined total time interval T may be excluded from the touch communications connection sequence.
Step 807
Determine if any touch communications connection has been established. If yes, go to the step 809, if not, go back to the step 803. This step may be performed by a processing unit of the first touch panel device, a processing unit of the second touch panel device, or both. The touch communications connection may be established by one or both of the first and second touch panel devices with aid of one or both of the first and second touch panels. In the exemplary embodiment that the touch communications connection sequence includes a plurality of touch communications connections, if only one touch communications connection is established so far, the touch communications connection sequence is not formed thus the step 809 is not needed yet.
Step 809
Determine if the touch communications connection sequence follows a recognizing rule. A determining result may be generated accordingly. If yes, go to step 811, if not, go back to the step 803. This step may be performed by a processing unit of the first touch panel device, a processing unit of the second touch panel device, or both.
Step 811
Perform a predetermined operation. The predetermined operation may be performed based on the touch communications connection sequence. More particularly, the predetermined operation may be performed based on the determining result generated in step 809. The processing unit of the first touch panel device may control the first touch panel device to perform the predetermined operation.
Step 813
End.
Please note the steps illustrated in FIG. 8 are only an example and does not mean to limit the scope of the present application. The steps may be executed in any other order and one or more steps may be omitted. For example, step 809 may be executed before step 803, between step 807 and step 809, after step 809, or after step 811. Besides, in some exemplary embodiments, step 809 may be omitted.
