[Prior Art] With the rapid development of technology, most electronic devices, such as notebook computers, mobile phones, or portable multimedia players, are usually equipped with touch panels to replace the traditional keyboard as a new generation input interface. . The touch panel can be roughly classified into a resistive type, a capacitive type, an infrared type, and an ultrasonic type. Among them, a resistive touch panel and a capacitive touch panel are the most common products. The capacitive touch panel changes the capacitance value of the touch panel by approaching or touching the touch panel via a finger or a conductor material. When the touch panel detects a change in the capacitance value, it can determine the position of the finger or conductor material that is close to or touched, and perform the function operation corresponding to the touch position. Capacitive touch panels have the characteristics of multi-finger touch and provide humanized operation, which is gradually favored by the market. In the touch panel of the self capacitance (also referred to as absolute capacitance), the Axis intersecting (Profile-based) is used to configure the diamond shape sensor on the conductive layer, and A conductive layer is required for each axial direction.

When the first:,; 2 measured capacitance value line value; -= line and its adjacent scanning control panel is in the first - age setting, and the setting touch is in the single finger touch state, the order is When the touch panel senses the capacitance value respectively, it is determined whether the scan line is the second wave. When the capacitance value sensed by the second woman trace line is, the capacitance value of each scan test value is sequentially extracted and the capacitance value sensed by the second wave line is respectively detected, and 5 201039221 ιιπ-υ〇-υιζ 30302twf .doc/n When the capacitance value is taken, the second complement position is calculated according to the detected capacitance values of the second scan line and its adjacent scan lines, and the touch panel is set to be in a multi-finger touch state. In the above-mentioned positioning method, when the touch panel is in the multi-finger touch state, the capacitance value of the first-scanning line is still the first peak and the second scanning line is detected.

The first peak indicates that the letter is lost. The single finger touches the state. When the first-sweep setting touch panel is in the value dispersion or the capacitance indication signal sensed by the poor senser and the second sensor is a peak, the peak state produces an initial state. The invention is also provided with a touch panel positioning method, which enables the touch surface 7 201039221 ιιπ-υδ-υιζ 30302twf.doc/n board to have multiple scanning lines . First, a plurality of capacitance values respectively sensed by the scan lines are sequentially captured. Then, according to the capacitance values respectively sensed by the first scan line and the adjacent scan lines of the scan lines, it is determined whether the capacitance value sensed by the first scan line is the first peak. When the capacitance value sensed by the first scan line is the first peak, whether the first scan line corresponds to the first sleeve. When the first scan line corresponds to the first axial direction, and the first peak corresponds to the first axial direction, the scan line corresponding to the second axial direction is scanned to have a capacitance value of a first peak. When the first scan line does not correspond to j::: represents that the first material corresponds to the second axial direction, the line corresponding to the first-axis is scanned to obtain the capacitance value corresponding to the first scale of the first axial direction. According to the capacitance value of the first peak corresponding to the first axial direction and the second axial direction, the touch position of the younger brother is calculated, and the touch panel is set to be in a single finger touch state.

Further, by controlling the setting of the touch state to control the mutual operation of the components in the device, the calculation amount of the riding position can be effectively reduced. The above-mentioned miscellaneous and gamma-deficient details of the present invention will be described in detail below with reference to the accompanying drawings. [Embodiment] One of the first embodiment of the present invention is a positioning device and a touch panel of the present invention. Referring to Figure m, the touch panel 50 is, for example, a capacitive touch surface (for example, an X-axis). Or the corresponding conductive layer 1 axis parental error mode (prGflle_Based) for the diamond shape sensor 9 201039221^ 丄丄r ι-υο-υ j〇302twf.d.oc/n configuration. In the present embodiment, the scanning lines CIN0 to CIN7 on the conductive layer corresponding to the X-axis are arranged with the sensor 1A in the Y-axis direction, and the scanning lines CIN8 to CIN15 on the conductive layer corresponding to the γ-axis are arranged along the X-axis direction. The sensor 20° positioning device 100 includes a multiplexer 11A, a converter unit 12A, and a processing unit 130. Since the multi-finger touches the touch panel 5 通常, there is usually a time difference, so the positioning device 1 〇〇 utilizes the time difference between the multi-finger touches, and after the corresponding touch position is completed, the front finger does not end. After the touch, the finger is pointed to the position of the corresponding touch position to eliminate the mirror point generated by the multi-finger touch. Further, in the present embodiment, each element in the positioning device 100 is controlled by setting the state of the touch panel 5, for example, a single-finger touch state, a multi-finger touch state, and no touch-like evil. The operation of each component in the positioning device 100 will be described below one by one. The multiplexer 110 is coupled to the touch panel 5A. When a touch tool (for example, a hand or a battery pen) contacts the touch panel 50, the conductive layer and the touch tool are electrically coupled to cause a change in the capacitance value sensed by each of the scan lines. When the touch detection of the touch panel 50 is performed, the multiplexer 11 sequentially captures the capacitance value sensed by each scan line according to the order of the scan. For example, the scan order is sequentially the scan lines CIN0+ CIN1...+CIN7 and ^Tian, Izumi CIN8+CIN9...~>cmi5. By measuring the coordinates of the touched position on the conductive layer corresponding to each j, the touch position can be positioned by the two-dimensional coordinate. ^Change S12 (H column is a capacitor digital converter (c叩adt_to lgltalconverter, CDC)') coupled to the multiplexer 110 and the processing unit 130 10 201039221 χιπ-υ6-υι2 3〇3〇2twf.doc/n The unit 120 is configured to convert the capacitance value of the analog format into a capacitance value of the digital format for the processing unit 130 to interpret and process. The processing unit 130 is, for example, a microcontroller (micro_contr〇ller), which is multiplexed. The processing early element 130 includes a touch detector 131, a peak value detection 5|132, and a clamp operation unit I%. 峰值 The peak detector 132 is coupled to the conversion unit 12〇 and the positioning operation unit 133: the touch tool touches the touch When the control panel is 5 ,, the electric valley curve sensed by the scan lines forms at least one peak. Since the peak can indicate the scan line of the touch tool _, and the number of peaks can indicate the touch panel 5 The number of positions touched by the touch guard, so the peak detection ϋ 132 will measure the debt, and the corresponding peak indication signal PEAK_IND is generated to control the multiplexer 110 to re-train the scan line to observe the multiplexer no. Produce a scan when the capacitor value is taken Break = CQNV - INT to (4) Positioning unit 133 riding position _ position. The unit operation unit 133 is coupled to the conversion unit 120. Generally, t, the scanning line position of the 〇 ϋ is close to the touch position. The resolution of the touch sensor display of the sensor is generally higher than the nil size of the sensor configuration, which relatively reduces the detected touch position, 瞎, 2, the 'clamp operation unit 133 Receiving the peak indication letter 5, the snow dice and +! The scanning line of the sub-wave peak and the position of the adjacent scanning line sensed, and the touch panel 50 is touched by the touch tool to improve the accuracy of the positioning. The touch detector 131 is connected to the peak detector I32 and coupled to the multiplexer 11 via the conversion unit 30302twf.doc/n 201039221 120. When the sensed capacitance of the scan line is greater than the touch threshold, the touch detection The device 131 generates a proximity interrupt signal STAGE-INTI (four) positioning operation unit 133 is ready to operate. Thereby, the touch panel 50 can be prevented from being touched or approached by the touch tool, and the positioning device 1GG is necessary for the capacitor. Borrowing the consumption of low system computing resources. 2 is a flow chart of a method for positioning a touch device according to an embodiment of the present invention. Referring to FIG. 1B and FIG. 2, when the touch panel 5 is initially untouched, the positioning device 1 is initialized. (Step 2〇1), and the touch panel 50 is set to be in a no-touch state (step 2〇2). Then, the multiplexer sequentially switches the scan lines, and then the conversion unit 12G senses the capacitance value on each scan line. _Check_131 compares the capacitance value of each sweep with the touched private value to determine whether the touch panel 5 is approached or touched by the touch tool. When the touch panel 5 is touched by a touch tool at a single position (for example, the stone contact position A), some of the scan lines corresponding to the x-axis and the scan lines CIN8 to C corresponding to the Y-axis are subjected to The touch tool is touched or 接近 close to make money, so that the (four) capacitance value will be greater than the touch threshold. At this time, the touch detector 131 generates a proximity to the Shanghai STAGEJNT to the fixed calculation unit 133, and (4) is ready to operate. According to the scanning and line CIN0~CIN7 corresponding to the X-axis, the period value detector I32 determines whether the capacitance value is corresponding to the X-axis according to the capacitance values respectively sensed by the scanning lines and the adjacent scanning lines. The first wave of the layer (step 203). It is known whether the touch panel 5q is ^ 12 经由 via the side of the first peak.

201039221 χία χ-ν〇-υ!2 30302twf.doc/n Single finger touch. Similarly, the capacitance value 132 on & CIN8 to CIN15 also detects the scan line peak. The value of the value of the value of the first wave to the single finger of the Y-axis conductive layer is detected by the peak. It can be known whether the touch panel 5G is fixed or not. The second position; 3 error-free capacitance value, resulting in the calculation, + correct. Therefore, when the peak detector 132 detects the corresponding capacitance value on the corresponding 5 (four) scan line, the peak value is detected, and the peak value is detected. Wave • Indication signal off 3 delete = control eve J1 5 11 〇 Re-sequence to capture the corresponding χ axis and γ axis of the scanning 观 Capsule capacitance value, and when the capacitance value sensed on each line is taken ' A scan interrupt signal C0NVJNT is generated. The scanning sequence is, for example, the scanning line CIN0+ ciNUmbo^c· 乂5, and the multiplexer 11 generates a scanning interrupt signal C〇NV_INT after the H-finger 2G sensing capacitance value is taken on the scanning line CIN15. When the clamp operation unit 133 receives the scan interrupt signal c〇NV INT, the first touch position is calculated according to the capacitance values respectively sensed by the scan lines corresponding to the first peak and the adjacent scan lines ( For example, the position A) is touched (step 204), and the touch panel 50 is set to be in a single-finger touch state (step 205). In this embodiment, the first peak indication signal PEAK_IND1 generated by the peak detector 132 can control the touch detector ι31 to disable the operation of the proximity interrupt signal STAGE_INT to avoid the positioning device 100 at the first touch position. Before the positioning, the operation of the touch panel 13 30302twf.doc/n 201039221 is inadvertently touched by another finger. In the positioning process of the first-touch position, the multiplexer n〇 is still continuously sensing the electric power sensed on the scan lines corresponding to the X-axis and the γ-axis, and the touch panel 50 is set to the single-finger_state. The peak detection 132 determines whether the second peak is based on the valley value of each scan line and its adjacent scan line (step 206), thereby knowing whether the second panel 50 is touched by the multi-finger. When each sweep s σ touches the second peak, the peak detection, line: the capacitance sensed by the sensed electrical scan line. No still - the peak of the genius ~ η is the brother - peak (step 2 〇 7). Right first, then the corresponding sensor is still the first peak, then the first-touch position of the panel 50 is still (four) touch, which is ^ in the single-finger touch state (step 2〇5). In addition, the peak detection yield \g knows that the touch panel % is not _, so the peak indication money (10) defeat operation unit mi control panel 5G is in a non-touch state (step view ~ although the peak detector i32 detects the corresponding axis or ^斤感感值为第二波料, peak detector 132; generate the first peak buckle signal PEAK-IND2, to

The value (step 20δ), and the control multiplex II 110 is used to extract the Ray H^ raw scan towel off signal C0NV JNT. Thereby, the stability of the capacitance value to be taken can be ensured by re-extracting the scanning capacity, and then the quasi-determination of the untouched position is determined. At this time, the conductive layer of the early-axial (X-axis or γ-axis) may have two. 14 i2 30302twf.doc/n

'Peak detector 132 will detect the previous ^; second: shape: : Whether the capacitance sensed by the line is still the first peak, upper; should be the second peak of the scan line It is determined whether the capacitance value is still in step 210). When the value of the peak of the scan line or the second material does not exist, the table reports the detection, and the i32 generates the first peak indication signal pEAKjNm to control the positional unit 133 to set the touch panel % to be in a single finger touch. Status 乂, 205). When the capacitance value sensed by the scan line is that the first wave and the other peak are not present, it indicates that the number of peaks changes from 2 to 〇, so the peak detector 132 generates an initial indication signal to control the positioning operation unit 133 to initialize the touch panel 5 〇 is in no touch state (steps ~2〇2). When the touch panel 50 is touched by the touch tool (for example, the touch positions A and B), the corresponding X-axis and γ-axis conductive layers respectively have two peaks. In general, the two fingers do not touch the touch panel at the same time and store the time difference (for example, 5 〇 milliseconds) after touching the touch panel 50. As the processing speed of the electronic device is continuously increased, it is sufficient to locate the touch position corresponding to the front finger within the time difference. Then, when the back finger touches the touch panel 5〇 successively, 'the Ghost Point' can be eliminated by excluding the touch position corresponding to the front finger to correctly position the rear 15 201039221 ιχπ-υ〇 -υιζ 30302twf.doc/n Refers to the corresponding touch position. 3 is a first diagram of a touch panel according to another embodiment of the present invention. Referring to FIG. 3 and FIG. 3, firstly, when the touch panel 5 is touched, the touch panel 5 is set to be in a non-touch state (step ^. The receiver's multi-wang 11 11G will sequentially turn on the axis. The capacitance value is measured (step moving), and the touch detection determines whether the touch surface β is not, ± ^ 50 (4) l is touched according to the capacitance value captured. When the touch surface detector 132 then judges the captured The capacitance value is 〇 = brother: !: Γ 3). When the #_capacitance value = 30 V Γ is the corresponding axis (the step is still in the no-touch state (step 301). The scan line that the field touch panel 50 is picking up is Corresponding to the X-axis 132 corresponding to the capacitance value of the trace to obtain the first peak of the axis (step 305); otherwise, the brother-wave has obtained the 'received record', and the capacitance value of the scan line corresponding to the X-axis is obtained to obtain the pair. Hi, Γ11 by 0 Π!). In the corresponding first-wavelength peak corresponding to the x-axis and the γ-axis, the 运-transportation 133 is based on the first touch position (4) such as: _ bit [magic, and set the single finger touch state (step 307). The I panel 50 is in the same manner, and the capacitance value sensed by each of the touch panel 50 is sequentially extracted (step (10)). The capacitance value extracted by the 1_jin is judged whether the first peak is = 16 oo 201039221 lirx-vo-ux2 30302twf.doc/n Step 309). When the value of the capacitance captured by the first peak is m(9)m, then the value of the capacitance taken is the first day (step 310). When the scanned line is ^, the peak detector 132 determines that the positive board is being received. When the second peak of the touch surface has been obtained, the multiplexer 132, which represents the corresponding X axis and the corresponding Υ axis, controls the multiplexer 110 peak (step 312); The second wave corresponding to the x-axis and then the peak detector 132 will trace the capacitance value of the line to obtain the second element after the second element is obtained, the bit operation is as follows, the position V skin: the second touch position ( Example (the step is in the multi-finger touch type 5.

In step 310, when the captured capacitance value is not f two peaks, the peak detector 132 controls the positioning operation unit 133 to set the touch panel 5 to remain in the single finger touch state. It is to be noted that the embodiment can control the operation of each component in the positioning device 1GG in a firmware manner, and is not limited to the implementation of the hardware. For the control method, refer to the process of FIG. 2 of the embodiment. As described above, the above embodiments provide a touch panel positioning device and a clamping method, which can set the state of the touch panel via peak detection, such as: no touch, single finger touch, and more Refers to the state of contact, etc., to control 2 positioning, the internal components operate with each other. Moreover, the multi-finger touch usually has a characteristic of the time 'after the first-to-touch position corresponding to the front finger and before the front finger is not finished, the second touch corresponding to the positioning finger is Set to exclude mirror points generated when multi-finger touches. Thereby, the positioning accuracy of the touch position can be improved.
