Second Embodiment FIG. 2 is a top plan view showing a conductive film, an electrode, and a wire in a touch device according to a second embodiment of the present invention. Referring to FIG. 2, the touch splitting of the present embodiment is similar to the touch device 100 of FIG. 1B, and the main difference between the two is that the touch device of the embodiment has the first auxiliary electrode 2 and the second The third auxiliary electrode 2 of the auxiliary electrode 240a' but not ϋ1B is mapped to the fourth auxiliary electrode 240b. In other words, in the present embodiment, there is only one auxiliary electrode 22' on the first side S1, and only one auxiliary electrode 24'' on the second side S2. Third Embodiment Fig. 3 is a flow chart showing a control method of a third embodiment of the present invention. Referring to FIG. 1A, FIG. 1B and FIG. 3, the control method of this embodiment is suitable for controlling the touch device 100 of the above embodiment. This control method includes the following steps. First, step 201108055, step S10, is performed to alternately turn one of the first electrode 210 and the first auxiliary electrode 22A into a read state, and apply a second reference voltage to the second conductive film I20. In this embodiment, the first electrode 210, the auxiliary electrode 22, the second electrode 230, and the auxiliary electrode 240 are electrically connected to the driving circuit (not shown) through the wire 26, for example, to drive an integrated circuit (driveimegrateddrcuit, Dnve 1C). In the present embodiment, the driving circuit is adapted to cause the electrodes connected thereto to assume two different states, a driving state and a reading state. In the driving state, the dynamic circuit applies -[reference voltage to the electrode connected to it, and in the state of φ, the driving circuit causes the electrode to be in a floating state or a high impedance state. At this time, the driving circuit does not apply a voltage to the electrode connected thereto, and is adapted to read the voltage of the electrode connected thereto. In the present embodiment, the first electrode 21 is sequentially read by the first electrode 21 and the first electrode 21 is in a read state. Further, applying the second reference voltage to the second conductive film 120 can be achieved by applying a second reference voltage to the third electrode 25A. When any of the first electrode 210 and the first auxiliary electrode 22 are electrically read, a first reference voltage is applied to the other of the first and second auxiliary electrodes 220a. In the present embodiment, the first reference voltage is also applied to the third auxiliary electrode 22A at this time. For example, when the first electrode 21c is in the reading state, the first reference electrode is applied to the first electrodes 21 to 210b and 210d to 210e, the first auxiliary electrode 22a and the third auxiliary electrode. However, in other embodiments, when any of the first electrode 21〇 and the first auxiliary electrode are in the reading state, only the first reference voltage may be applied to the first electrode 21〇 and the first electrode. A part of the other electrode of the auxiliary electrode is, for example, a first reference voltage applied to the electrode 12 201108055 in the read state. In addition, the H test voltage is not equal to the second reference: the first reference voltage in the embodiment is, for example. Volts, while the second reference voltage = 5 volts', but the invention is not limited thereto. p when these electrodes: the electrode closest to the second region A2 of the electrode 21G (in the present embodiment, the first electrode) is in a reading state, at least
輔助電極24〇a *被施加電壓，例域於讀取狀態，亦即此時 為了增加第-電極21Ge所讀取出的電壓值之準雜，相對於 其之第二輔助電極2術可處於浮動態或高阻抗態，而不要處 於驅動狀態，這可避免第—電極2lGe所讀取到的電壓值受到 第二輔助電極識的干擾。__電極施處 „ 了讀取雜值，而是為了處於浮動態或高阻抗態^ 第一辅助電極施*被施加電壓，因此㈣鶴電路可不讀 取第二輔助電極她的電壓值，或者即使讀取了電壓值，此 電壓值也不採用。 同理，當第一輔助電極22〇a處於讀取狀態時，至少使第 ^電極230中之最靠近第-區A1的電極（在本實施例中即為 弟-電極23Ge)不被施加電壓，例如處於讀取狀態。此時， 驅動電路可讀取到第一輔助電極220a的電壓值，但不讀取第 二電極23〇e的電壓值，或者即使讀取了第二電極23〇e的電壓 值’但此電壓值亦不被採用。 ^同理，在本實施例中，當這些第一電極210中之第二靠近 第，區A2的電極（即第一電極21〇d)處於讀取狀態時，至少 ，第四辅助電極240b不被施加電壓，例如處於讀取狀態。此 寸驅動電路可讀取到弟一電極2i〇d的電壓值，但不讀取第 四輔助電極240b的電壓值，或者即使讀取了第四輔助電極 240b的電壓值，但此電壓值亦不被採用。 13 201108055 由於當第一電極2l〇b〜21〇d在讀取狀態時，其兩旁的電 極皆處於驅動狀態，因此為了使第一輔助電極22〇a也有這樣 的環境，在本實施例中，當第一辅助電極220a處於讀取狀態 時，將施加第一參考電壓至第三輔助電極22〇b。為了進一步 提升讀取環境的一致性，在本實施例中，當這些第一電極21〇 中之任一個電極處於讀取狀態時，亦可施加第一參考電壓至第 三輔助電極220b。The auxiliary electrode 24〇a* is applied with a voltage, for example, in a read state, that is, at this time, in order to increase the quasi-interference of the voltage value read by the first electrode 21Ge, the second auxiliary electrode 2 can be in contact with the second auxiliary electrode 2 The floating dynamic or high-impedance state is not in the driving state, which can prevent the voltage value read by the first electrode 2lGe from being interfered by the second auxiliary electrode. __The electrode is applied to read the miscellaneous value, but to be in a floating or high-impedance state. The first auxiliary electrode is applied with a voltage, so (4) the crane circuit may not read the voltage value of the second auxiliary electrode, or Even if the voltage value is read, the voltage value is not used. Similarly, when the first auxiliary electrode 22a is in the reading state, at least the electrode of the second electrode 230 closest to the first-region A1 (in this case) In the embodiment, the transistor-electrode 23Ge is not applied with a voltage, for example, in a read state. At this time, the driving circuit can read the voltage value of the first auxiliary electrode 220a, but does not read the second electrode 23〇e. The voltage value, or even if the voltage value of the second electrode 23〇e is read, but this voltage value is not used. Similarly, in the present embodiment, when the second of the first electrodes 210 is close to the first, When the electrode of the region A2 (ie, the first electrode 21〇d) is in the reading state, at least, the fourth auxiliary electrode 240b is not applied with a voltage, for example, in a reading state. The inch driving circuit can read the second electrode 2i〇 The voltage value of d, but does not read the voltage value of the fourth auxiliary electrode 240b, Or even if the voltage value of the fourth auxiliary electrode 240b is read, the voltage value is not used. 13 201108055 Since the first electrode 21sb~21〇d is in the reading state, the electrodes on both sides thereof are driven. State, therefore, in order for the first auxiliary electrode 22A to have such an environment, in the present embodiment, when the first auxiliary electrode 220a is in the reading state, the first reference voltage is applied to the third auxiliary electrode 22〇b. In order to further improve the consistency of the reading environment, in the embodiment, when any one of the first electrodes 21 is in the reading state, the first reference voltage may be applied to the third auxiliary electrode 220b.

Step S120 is similar to step S110. The difference between the two is mainly that the control object is a different electrode, and the effect to be achieved is the same. Therefore, only the step valve sl2〇 is briefly described below, and the details refer to the description of step Sii〇. . Step s12 turns to make one of the second electrode 23A and the second auxiliary electrode 240 in a read state (for example, sequentially making the second electric, the illusion %~23 as being read with the second auxiliary electrode 24〇) The state is taken), and a second reference voltage is applied to the second conductive film 120. When any one of the second electrode 230 and the auxiliary:pole 24A is in a read state, a first reference voltage is applied to at least a portion of the other of the second electrode 230 and the second auxiliary electrode 240a. . When the second of the second electrodes 230 closest to the first region A1 is in the reading state, at least the first auxiliary electrode 240a is not applied, for example, in a reading state. When the second auxiliary electrode 24a is in the read band, at least the electrode of the first electrode 210 closest to the second region A2 is not subjected to, for example, a sigma voltage', for example, in a read state. First, in the present embodiment, when the second of the second electrodes 230 is close to the electrode of the first region (ie, the second electrode 230d), at least the auxiliary electrode 22〇b is not Apply voltage, read, drive t/j Christine. The A ^ two auxiliary * circuit can read the voltage value of the second electrode 230d, but does not read the voltage value of the second auxiliary electrode 220b, or even if the voltage value of the third auxiliary electrode 201108055 220b is read, the voltage value is also Not used. In addition, in the present embodiment, when the second auxiliary electrode 240a is in the reading state, the first reference voltage is applied to the fourth auxiliary electrode 24〇b so that the reading ring of the second auxiliary electrode 24Ga is read. Close to other electrodes. In order to improve the consistency of the reading environment of the k-liter, in the present embodiment, when any one of the electrodes 230 is in the reading state, the first reference voltage may be applied to the fourth auxiliary electrode 240b. I have to pay attention to the fact that the order of execution of the present invention is the first step.

Specifically, when the touch device 100 is pressed, the first electrode 21A and the second electrodes 23〇 respectively include an extreme value among the plurality of voltage values sensed in the read state. In this embodiment, since the first reference voltage is smaller than the second reference voltage, this extreme value is a maximum value and is greater than the first reference voltage. The control method of the embodiment further includes calculating, according to the extreme value and the two voltage values respectively sensed by the two electrodes adjacent to the electrode sensing the extreme value, the touched device is pressed (ie, touched Point) a position in a direction substantially parallel to the first side S1 (i.e., the gamma direction). In addition, the third electrodes 250 respectively include an extreme value among a plurality of voltage values sensed in the read state.

And a third sensing electrode. The first voltage signal is derived from the first, measuring electrode, the extreme voltage signal is derived from the second sensing electrode, and the second voltage signal is derived from the third sensing electrode. The second sensing electrode is located between the first sensing electrode and the third sensing electrode, and the second electrode is adjacent to the first sensing electrode and the third sensing electrode, respectively.
