[Prior Art] A capacitive touch panel generally used for a touch device is mainly composed of a glass substrate, and a set of horizontally arranged sensing lines and a set of vertically arranged sensing lines are deposited on the glass substrate, wherein the group of levels A plurality of interlacing points are formed between the sensing line and the set of vertical sensing lines on the glass substrate. When the user of the touch device approaches the touch panel with a finger, the capacitance between the horizontal sensing line and the vertical sensing line is changed at the staggered point (also referred to as a contact point) that the touch device contacts; A capacitance sensing driver (Charge Sensing Driver) may be additionally provided to sense the change of capacitance between the horizontal sensing line and the vertical sensing line to determine whether it is touched by the user's finger and decide to use according to the movement mode touched by the user. The instruction that the person wants to trigger. The prior art has Self Capacitance detection and Mutual Capacitance detection. Two detection technologies used in capacitive touch panels are used to confirm that 201126400 users use the hand & (4) On-board triggering turning point (τ(4)(4)(4). Please refer to Fig. 1 for illustrating a partial schematic diagram of implementing a mutual capacitance biasing technique on a capacitive touch panel excitation. The labels are labeled Χ1, χ2, χ3, χ4 The vertical line of χ5 represents a part of the vertical sensing line on the capacitive touch panel hall. The horizontal lines marked as phantom, Υ2, Y3, Υ4, and Y5 represent some of the horizontal sensing lines on the capacitive touch panel. The icon represents the actual touch of the user on the capacitive touch panel. The plurality of real points PI Ρ2 Ρ3 are located at the intersection of the horizontal sensing line and the vertical sensing line. The system represents the mutual capacitance detection technology in the capacitive touch panel. The contact point to which it should be placed. As shown in the figure!, when the mutual capacitance detection technology is implemented in the capacitive touch panel shown in Figure 1, the reset is first sent to the horizontal sensing line γι_γ5. Signal, in order Pulling the corresponding horizontal sense wire to a predetermined potential, and sequentially sensing the capacitance change on the vertical sensing lines Χ1-Χ5 to detect an accurate succession on the capacitive touch panel. For example, when When the reset signal is sent to the horizontal sensing line γ2, the horizontal sense Lin 2 will be full of storage, and the Qianlin χι_χ5 will be detected in turn and the capacitance is changed by the user's contact in the vertical sensing lines Χ2 and X4. It-shaped' Therefore, the capacitive touch panel 丨(8) can determine the capacitance change at the two intersections on the horizontal sensing line w^ ^^^^^, X4, and X4, and determine the contact point with the Litian to the horizontal sensing line Y4. When the reset signal is sent, the capacitive touch panel 100 only detects the change in capacitance at an intersection of the horizontal sensing line 4 and the vertical sensing line X4, and the mosquito is connected to the p3. The mutual capacitance detecting technology is available. To achieve the handle contact, 3⁄4 细 足 foot of the township control (a (10) 丨 fine sound technology 'however' because of the need for the horizontal sensing line 丫 5 and vertical sensing line And detection, making capacitive touch panel 2011 26400 ! 相当 相当 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜 铜The self-capacitance detection technology performs the contact point _ in a relatively fast manner, and the capacitive touch panel _ can satisfy the user's instant touch. See Figure 2, which is used to illustrate the capacitive type. The touch panel is implemented on the brain _ _ _ sub-schematic diagram, the second _ mark of the towel is not repeated with the i-th picture. As shown in Figure 2, when the self-capacity detection technology is implemented in the first figure When the #type touch panel is not used, the horizontal sensing line YU is simultaneously sent a plurality of reset signals 'to pull all the horizontal sensing lines to -[predetermined f-bit, and at the same time in the vertical sensing line Xl_X5Jl performs the induction of the capacitance change on the vertical sensing line χι_χ5. Find the vertical sensing of the change of the capacitance. The potential of the horizontal sensing line will be reduced to zero. Vertical sense of hiding 1_Χ5 while sending Wei number health, (10) Cai Qian Qianlin rose to The first-predetermined potential, and at the same time, the sensing of the capacitance change on the horizontal sensing line 7 (7) 'so that the electric valley touch panel 1 〇〇 will know which vertical sensing lines and which horizontal sensing lines are triggered For example, the actual contact age of the same i-th is, first, the horizontal sensing line Υ1·Υ5 is pulled up to the first-on potential, the capacitive touch panel 100 detects the vertical sensing, the lines X2, X4 Capacitance change; then, when the horizontal sensing line Y1-Y5 is pulled down to zero, and the vertical sensing line χι_χ5 is pulled up to the second predetermined f-bit, the capacitive touch panel is surveyed to the horizontal sensing line γ2, Υ4 The capacitance on the change. Combining the results of the above vertical sensing lines χ2, χ4 and horizontal sensing lines, and the capacitance on 201126400 Y4, the capacitive touch panel brain will determine the multiple intersections on the horizontal sensing lines Υ2, Υ4 and the vertical sensing lines χ2, χ4. For the contact points PI, Ρ2, Ρ3, Ρ4. However, in essence, the user only triggers the contact point ρ Ρ 2, Ρ 3 ' without touching the contact point detected when the self-capacitance detection technology is implemented; this is because the self-contained _ technology is essentially off _ all vertical When the sensing line is detected, the square wire of all the horizontal sense lines is determined to be used by the face, and accordingly, the higher speed than the mutual capacitance detection technology is achieved, but the partial precision is also sacrificed: The misjudgment of the contact point Ρ4 is shown in Fig. 2. In other words, since self-confidence is not as good as implementing mutual capacitance _ technology, it is misjudged for each ^ sensor line intersection on the capacitive touch panel, and shame can not satisfy the real point. The need for touch. SUMMARY OF THE INVENTION The present invention discloses a method for performing a (four) chirp on a capacitive touch panel.

When the number of candidates has been covered All the first lines of the contact point are detected after the corresponding capacitance change on the second sensing line of the plurality of lines: when 'execution step 316' is performed, otherwise step 316 is performed; and step 316:= sequentially refers to the plural number covering the complex number _ selection contact point The first sense of the strip corresponds to the detected capacitance change on the second sensing line of the plurality of strips; *匕 the plurality of actual contacts 201126400 are found by the number of candidate contacts, wherein steps 302 to 310 are the above-mentioned In one stage, the self-capacitance detection technology is used for the capacitive touch panel 1; and steps 312 to 316 are the second stage of the present invention described above, that is, the mutual capacitance_technology is used for the capacitive touch panel 100. . The following related explanations will be based on the diagram in Figure 2. In the first stage of the method disclosed in the present invention, first, in step 3〇2, the potentials of all the horizontal sensing lines Υ1_Υ5 included in the capacitive touch panel 100 are pulled up to a first potential in a reset manner, and In step 304, the capacitance change measurements are performed on all the vertical sensing lines Χ1-Χ5 included in the capacitive touch panel to determine which vertical sensing lines in the vertical sensing lines Χ1-Χ5 are triggered by the user. Then, in the step, the potential of the (4) wire included in the capacitive touch panel 1()() is pulled up to the second potential in a reset manner, and the capacitive touch panel 1 is simultaneously applied in the step.所有Include all the horizontal sensing lines ¥1_¥5 for capacitance change detection to determine which of the horizontal sensing lines Υ1-Υ5 are triggered by the user. In step 灿, all the intersections between all the horizontal sensing lines and the vertical sensing lines detected in steps 3〇4 and 3〇8 are determined as a plurality of candidate contact points. For the contact points triggered by the user in Fig. 2, the candidate contact points determined after the execution of steps 3〇2 to 31〇 are PI, Ρ2, Ρ3, and Ρ4. In the second phase of the method disclosed by the present invention, the range of sensing lines measured by the mutual capacitance_technology will be limited to a plurality of penalties of the plurality of candidate contact points interleaved in the first stage _ The water is not the same as the one used in the prior art for the capacitive sensing board 1〇(), which has a carpet line type. Therefore, compared with the 201126400 technology, the amount of data can be reduced and the amount of TA can be saved. The location detection technology can accurately find out the characteristics of the contact point. In step 312, the first line of the sensor line is detected, and the line of the selected contact point is detected. Saki (10) should cover all the waters of the candidate contact points in the Υ1·Υ5 water + induction line U father's fault on the vertical scale (4) should be fully detected by the money
畢，並可根據步驟312、314中所得到的所有電容變化，由步細 所決定的複數個候選接觸點中剔除掉被誤判的候選接觸點，而留下 實際被使用者所觸發的接觸點。舉例來說，假設如第2圖所示，在 執仃本發明之方法的第-階段後所得到的複數個候選接觸點為 仏打、Ρ3、Ρ4 ’則在步驟312中會在水平感應線η”中僅僅針 對與候選接觸點PI、Ρ2、Ρ3、Ρ4有_水平感應線γ2、γ4做對 應之電容魏伽彳，而免去另行處理水平感應線〜γ3、γ5的處 時門w步驟312將水平感應線γ2進行重置以拉升其電位後， 曰將垂直感應線Χ1-Χ5逐一進行電容偵測以找出發生電容變化的接 觸點；由第2圖所示使用者的接觸情況可知，在垂直感應線χ2與 Χ4上都會發生電容變化。當步驟312將水平感應線料進行重置以 拉升^電位後’並難直感應線χ[χ5逐—進行電容_以找出發 電奋髮化的接觸點時’只能夠感應到垂直感應線χ4上的電容變 而無法感應到垂直感應線X2上的電容變化，此係因候選接觸 』二4實質上並未被使用者所觸發。综合步驟犯與別所偵測到的 電錢化結紐，f容糊控面板勘便可直翻定僅有(说幻卜 (Υ2’Χ4)、及〇邮4)二處交錯點產生有實質的電容變化，而未於 11 201126400 (Y4’X2)之交錯點上感應到實質的電容變化；亦即 此被剔除於候選接觸點之中，且剩下的候選接觸點P1、PL P3 ^ 後會被決定為接觸點。After that, according to all the capacitance changes obtained in steps 312 and 314, the candidate contact points that are misjudged are eliminated from the plurality of candidate contact points determined by the step details, leaving the contact points actually triggered by the user. . For example, assume that, as shown in FIG. 2, the plurality of candidate contact points obtained after the first stage of the method of the present invention is beaten, Ρ3, Ρ4' will be in the horizontal sensing line in step 312. In η", only the capacitance Weijia 有 corresponding to the candidate contact points PI, Ρ2, Ρ3, Ρ4 has _ horizontal sensing lines γ2, γ4, and the time gate 312 will be removed without separately processing the horizontal sensing lines γ3, γ5. After the horizontal sensing line γ2 is reset to pull up its potential, the vertical sensing lines Χ1-Χ5 perform capacitance detection one by one to find the contact point where the capacitance change occurs; the contact situation of the user shown in FIG. 2 shows that Capacitance changes occur on the vertical sensing lines χ2 and Χ4. When step 312 resets the horizontal sensing line to pull up the potential, it is difficult to directly sense the line χ[χ5--capacitor_ to find out the power generation When the contact point is changed, only the capacitance on the vertical sensing line χ4 can be sensed and the capacitance change on the vertical sensing line X2 cannot be sensed. This is because the candidate contact is not substantially triggered by the user.

The mutual capacitance cross-measurement technique, which requires more processing time, can thereby reduce a large amount of unnecessary processing time, and can still utilize the mutual capacitance detection technology in the gamma contact accuracy. In short, the present invention discloses that the high processing speed of the self-contained technology is combined, and the unnecessary processing amount is eliminated to greatly shorten the mutual capacity_technology processing, while the self-contained detection technology can be supplemented. Follow the contacts of the miscellaneous, in order to take advantage of real speed multi-touch. In addition, since a large amount of processed data has been eliminated before the second stage, the method shown in FIG. 3 can quickly and accurately lock the user in capacitive touch even in a large-sized touch panel. The panel touches the touch point that is triggered. In addition, although the example in the step Xianxun is to cover the part of the plurality of candidate contact points in the horizontal sensing line γ%, the potential reset is performed first, and the line Χ1·Χ5 is detected by In order to obtain the result of the change of the capacitance, in the example of the present invention, the vertical sensing line χ丨_χ5 can be firstly covered to a plurality of candidate portions for potential resetting, and then by the horizontal sensing line. Γι_γ5—detects the result of the change in capacitance to the actual contact point. In the step of moving to the viewing center, although the vertical sensing line γι_γ5 is reset at the same time to reset the vertical wire 12 12 12 26 26 nr type to perform the first stage of the capacitance change side, however, in the other case of the present invention The vertical sensing line Χ1-χ5 can be reset at the same time, and then the flat sensing line Υ5 is simultaneously re-leveled for the first-stage capacitance change detection. When resetting the water, it is possible to eliminate the accuracy of the contact point by using the other conditions to exclude the candidate contact points due to the implementation of the self-capacity side mode. For example, when the user's finger touches the capacitive touch panel, one of the palms has a contact with the touch panel: a capacitive touch panel triggers a large number of contact points, and: error. In an embodiment of the invention 'in order to exclude the portion that makes the board contact - and is judged to be triggered by the finger = after the end of step 310 of FIG. 3, they will be adjacent to each other _ the selected contact point is planned to be plural Candidate trigger regions, and according to the number of candidate touch regions, the number of candidate contact points, etc., and the direct palm phase feature of the candidate trigger region, the candidate contact points generated by the contacts of the dry touch panel are excluded, wherein each candidate touch All the contact points of the cover of the area 4 have a connected relationship of connected areas (Connected g). Please refer to FIG. 4 , which is a schematic diagram of generating a plurality of contact point regions on a portion of the capacitive touch panel 100 when the user touches the capacitive touch panel 100 with the palm and the finger, wherein the fourth The contact points on the capacitive touch panel 100 are also based on the representations of Figures 1 and 2, and it is assumed that the steps 3〇2_31〇 shown in Fig. 3 have been performed. In addition, for convenience of explanation, the horizontal sensing lines Y1-Y9 and the vertical sensing lines χΐ-χΐ3 shown in the figure also cover only one part of the capacitive touch panel. As shown in FIG. 4, when the user touches the capacitive touch panel 1 同时 with the finger and the palm 13 201126400, the part of the finger and the capacitive touch is a candidate covering a relatively small number of candidate touch points. The contact domain is in contact with the touch, and the palm and the capacitive touch panel are in contact with each other to form a candidate contact point area covering the relative vehicle" candidate contact points, wherein the candidate contacts are in the capacitive touch panel. (10) When there are sixteen or nine row steps 316, a predetermined number 9 is set to fourteen candidate contact points, and the number of blush candidate contact points is greater than or equal to the contact point area excluded from the last ant contact point.
