In this real customs towel, the debt measurement unit 211 will detect the first electrodes 221j~22u〇 first, wherein the first electrodes 221J~22U〇 can be sequentially _, but can also be detected simultaneously This can be based on the circuit design needs. It is assumed here that the touch point is p5, and (iv) the capacitance of the parent-to-error region of the first electrode 1-3 and the first electrode 223_4 changes, so that the first capacitance change is detected from the first electrode 221-3 ( That is, from the capacitance value co to ci). Next, the signal generating unit 213 sequentially inputs the signal S1 to the second electrodes 223-1 to 223_5, that is, the signals si are input to the second electrodes 223_1 to 223-5 in the order of the second electrodes 223-1 to 223_5. Herein, the signal S1 is exemplified by a square wave signal, but in other embodiments, it may be a level fluctuation signal such as a triangular wave signal or a sine wave signal. And in other embodiments, the input order of the signal Si may be the second electrodes 223 5 to 223 1 . When the signal S1 is input to the second electrodes 223__1 to 222-3 and 223_5, the capacitance value detected by the first electrode 221_3 is still ci. However, when the signal S1 is input to the second electrode 223__4, since the signal S1 is a square wave signal (ie, quasi 201224900 PT2010018TW-1 36071-ltwf.doc/n ==): ?, 221-3, the second electrode 2234 and the touch _Hand homozygous 'Mosquito number - the value will be changed from ci to C2 or ^ to the current amount), where the capacitance value CU is measured by the capacitance to the second capacitance change capacitance C1.

When the capacitance value of 221-13 is between MHz, the frequency of the first electric S1 is located at 6 MHz to H) When the value of the capacitance detected by -3 is changed from C1 to the second electrode 223 ^23 = when the touch is touched, the interleaved area of the first electrode work change I, if ρ Γ α 〜5 is regarded as having the first In a current culture, and when the signal S1 = 4 an electrode 221-3 angstrom second ray, to the first electrode 223-4, the second capacitance change amount, the _th „interlaced area will be regarded as having The six fine lπ aa is the wrong phase of the first electrode 221_3 and the second electrode is _ is the true touch position. 23~4 No.: Here, the touch point is P5 and P6 ' The first capacitance change is detected from ~3 and 221_8 respectively | The capacitance value is 〇)#Aci;5 Aihua|(ie, to the second electrode 22=5 2, then the signal S1 is sequentially rotated into 223 I, 99^ -1~223-. When the signal S1 is input to the second electric value and is still 'An~ and 223-5, the capacitance of the first electrode 221~8_ detected by the first electrode 221-3 The value is still C4.* Field h唬S1 input to the second battery极201224900 PT2010018TW-1 36071-ltwf.doc/n will change from C4 to C5 or C6 (that is, the second capacitance change), where the capacitance value C5 is greater than the capacitance value C4, and the capacitance value C6 is smaller than the capacitance value C4. The interleaved area of the first electrode 210-8 and the second electrode 223_2 is sequentially converted by having the first capacitance change amount to have the second capacitance change amount, so that the interleaved area of the first electrode 221-8 and the second electrode 223_2 is regarded as being When the nickname S1 is input to the second electrode 223_4, the measured value of the first electrode 221_3 is changed from C1 to C2 or C3 (ie, the second capacitance change amount). The capacitance value detected by the electrode 221__8 is still C4. At this time, the interleaved area of the second electrode 221_3 and the second electrode 223_4 is sequentially converted from having a cascode change amount to having a second capacitance change amount, so the first The staggered area of the electrode 221_5 and the second electrode 223_4 is regarded as true, touch, position. Thus, it can be determined whether the wrong area is determined according to whether the interleaved area is converted by having the first capacitance change amount to have the second capacitance change amount. True touch position, due to This does not produce a mirror shot. In addition, in other embodiments, the signal S1 can simultaneously input two first electrodes. For example, the 'second electrodes 223_1 and 223-5 first input the signal S1, then the second electrode 223-2 and 223_4 input signal S1, and finally second electrode 223-3 input signal S1', thereby shortening the time of touch point detection. The above sequence is illustrated by way of example, and in other embodiments, according to capacitive touch The size of the panel determines the number of second electrodes that simultaneously input the signal S1 and is self-contained with the order of design inputs. 4 is a schematic diagram of another touch detection of a capacitive touch device in accordance with an embodiment of the present invention.

If the touch points are P5 and p6, the detecting unit 211 detects the first capacitance change amount from the first electrodes 221-3, 221_8 and the second electrodes 223__2, 223_4, that is, the first electrode 221_3 detects The capacitance value of the capacitor is changed from C0 to C1, and the capacitance value detected by the first electrode 221-8 is changed from c〇 to C4. The capacitance value detected by the second electrode 223-2 is changed to C7, and the second electrode 223 The value of the detected capacitance of a 4 is changed from c〇 to c8.

Next, the signal generating unit 213 sequentially polls the signal S1 to the second electrodes 223-2 and us-4 to determine whether the interleaved region having the cascode change amount is a true touch position. When the signal S1 is input to the second electrode 222-3, the capacitance value detected by the first electrode 221-5 is still ci, and the capacitance value detected by the first electrode 221_8 is changed from C4 to C5 or C6 (ie, The second capacitance change amount). At this time, the interleaved regions of the first electrode 210-8 and the second electrode 223_2 are sequentially converted by having the first capacitance change amount to have the second capacitance change amount, so the first electrode 221-8 and the second electrode 223~2 are compared. The wrong area is regarded as a true touch position and recorded in the detecting unit 211. When the signal S1 is input to the second electrode 223-4, the capacitance value detected by the first electrode 221_3 is changed from ci to C2 or C3 (that is, the second capacitance is 4), and the first electrode is measured. The capacitor value is still C4.

The staggered area of the first electrode 221 - 3 and the second electrode 223_2 and the interleaved area of the first electrode 221__8 and the second electrode 223 - 4 are regarded as mirror points because they have only the first capacitance change amount.
