New description: [New technical field] [0001] [0002] This creation relates to a touch panel and its electrode structure, especially by increasing the touch. The effective sensing area of the electrode plate in the panel enables the capacitive touch panel and its electrode structure to increase the intensity of the signal. [Prior Art] Nowadays, more and more electronic devices can be used simply and intuitively without the need for complicated learning. 'The traditional physical button or mouse has been turned into a touch panel as an input device. The touch panel is a device attached to the display. The user can touch the finger or press the panel with a touch pen to obtain the required information. This technology not only omits the configuration space of the keyboard, but also Move the space to the display to increase the user's viewable area. At present, the touch panel mainly includes resistive, capacitive, optical and acoustic waves. The resistive touch panel is responsible for the work of the X-axis and Y-axis coordinates by the upper and lower sets of electrodes. 'The finger touches the panel and the upper and lower electrodes are contacted by the pressure to cause a short-circuit to generate a voltage change'. The x-turn and the γ-axis are alternately turned on and transmitted. The signal 'calculates the measured signal by the controller to obtain the touch position. The resistive touch panel is low in cost, but the sensitivity and transparency are still not effectively improved; the optical touch panel is mainly equipped with a transmitting source and a receiving source at both ends of the display, and the light source is used to receive the shielding principle, when the display is touched When touched, it will interfere with the transmission of the signal source, and the coordinates of the touch can be located. The acoustic touch panel forms a uniform sound field in the display area by the ultrasonic transmitter and receiver. When the sound form number A0101 is page 3 / A total of 22 pages M418341 100 September, 100, according to the positive replacement page wave hit the finger, the controller compares the amount of attenuation before and after use to calculate the touch position, the current optical and acoustic mode is mainly based on large-size display. At present, capacitive touch panels have higher penetration rate and more sensitive handling than other touch technologies, making the market share of capacitive touch panels more and more. The capacitive touch panel is composed of a sensing electrode, a wire and a microprocessor. When a finger touches the sensing electrode, the sensing electrode forms an electrical signal change, and the electrical signal is transmitted to the micro device via the wire, and the microprocessor according to the The electrical signal calculates the coordinates of the touched. | Refer to the first figure for a schematic view of a capacitive touch panel of the prior art. As shown in the figure, the capacitive touch panel 10 of the prior art comprises a transparent substrate 11 including a plurality of X-axis long straight strip sensing electrode arrays 12 and a plurality of X-axis transparent wires 121, and the plurality of x-axis transparent wires are straight. The sensing electrode array 13 and the plurality of x-axis transparent wires 131, the X-axis transparent wires 121 and the x-axis transparent wires 131 are respectively connected to the X-axis long straight sensing electrode arrays 12 and the long-axis sensing electrodes In the electrode array 13 to the controller (not shown in the first figure), the sensing electrode arrays 12, 13 are obtained by an etching process using a highly transparent material of Indium Tin Oxide (Indium Tin Oxide). IT0 materials have good transparency and low resistivity, and have good measurement results for small capacitors. The operation principle of the capacitive touch panel 10 is that the controller senses the change in the amount of charge generated by the finger touching the panel to determine the touch position. If the capacitance value of the finger touches the capacitive touch panel changes, the generated value is generated. The more the amount of charge, the more the amount of charge sensed, the less the distortion of the panel detection signal, and thus the sensitivity. According to the principle of the flat-plate capacitor, the capacitance value is affected by the overlapping area of the X and Y-axis electrodes. The larger the overlapping area, the more the capacitance value changes. Form No. A0101 Page 4 of 22 M4.18341

However, as shown in the first figure, the areas where the X and Y axis electrodes overlap each other are often limited by the too small sensing area, so the variation of the capacitance value cannot be effectively increased. This will easily cause the capacitance detection signal to be distorted due to the capacitance signal being too small, causing the X and Y axis touch positions to be misjudged, resulting in the capacitive touch panel being unable to accurately grasp the position of the finger touch. Therefore, this creation proposes a capacitive touch panel and its electrode structure for the above problems, and increases the overlapping area between the electrode arrays through changes in the electrode structure, in order to reduce the distortion of the capacitance detecting signal and avoid occurrence.

In the process of detecting the touch point, the amount of capacitance change generated by the finger touching the capacitive touch panel 20 affects the detection sensitivity, and the larger the capacitance change amount, the sensitivity of detecting the touch point is increased and the sensitivity is lowered. The panel detects the distortion of the signal. The parameter affecting the change of the capacitance includes the overlapping area of the conductor plate (ie, the first electrode 221 or the second electrode 231), the dielectric constant of the insulating layer, and the distance between the positive and negative conductor plates. The conventional capacitive touch panel is interleaved with the positive and negative conductor plates. The area is often too small, causing the capacitor signal to be too small and causing misjudgment of the touch position. Increasing the effective sensing area of the capacitive touch panel will solve this problem. In response to this problem, the capacitive touch panel 20 proposed by the present invention has the form number Α0101, page 7 / total 22 pages, M418341, and the first electrode 221 of the regular replacement page is a long straight strip. The first electrode array 22 is formed in a rectangular shape and arranged in a column arrangement; the second electrodes 231 respectively include a plurality of diamond-shaped conductor plates 2311, and the second conductor plates 2311 are connected in series with each other, and the capacitive touch panel 20 The second electrode 231 is formed in a row, and the first electrode array 22 and the second electrode array 23 are respectively interlaced, wherein the width of the first electrode 221 is larger than that of the second electrode 231. The width of the area of the electrode 221. In other words, the rectangular width of the first electrode 221 is greater than the diagonal length of the plurality of diamond-shaped conductor plates 2311 of the second electrode 231, since the second electrode 231 is formed by the diamond-shaped body plates 2311 in series, and the first The width of the electrode 221 is larger than the width of the area where the second electrode 231 is alternately overlapped with the first electrode 221. Therefore, the area where the first electrode 221 and the second electrode 231 of the present invention overlap is limited by the prior art. The overlapping area of the narrow line width is increased a lot, and the diamond-shaped area of the diamond-shaped conductor plate 2311 can be optimally adjusted according to the design requirements. The capacitance formula of the flat-shaped board is known, and the capacitance is proportional to the area of the conductor plate, so effective induction After the area is increased, the amount of capacitance change after the touch panel is touched by the finger is increased, and the distortion of the capacitance detection signal is reduced, 4 to reduce the misjudgment of the touch coordinates. In the touch point detection, the capacitive touch panel 20 of the present invention generates a scan signal by a control unit 21, and sequentially transmits the scan signals to the first scan/detection bus 211. An electrode 221, the control unit 21 further detects a detection signal of the second electrodes 231 of the second scan/detection bus 212 through the second scan/detection bus 212 according to the scan signal. Touch one of the touch points of the panel 20. That is, the control unit 21 can know the position of the touch point by the scan signal generated by itself, and then the control unit form number Α0101 page 8/22 pages M418341 100 years 09 On the 8th of the month, the correction replacement page 21 detects the detection signal by which the first electrode 221 is transmitted through the scanning signal, and detects the X-coordinate position of the touch point, so that the creation is The control unit 21 of the capacitive touch panel 20 can know the XY coordinate position of the touch point by scanning the signal and detecting the signal.

此外，本創作之電容式觸碰面板20之另一種偵測觸碰點的方法係由控制單元21透過第一掃描/偵測匯流排 211與第二掃描/偵測匯流排212產生掃描訊號與偵測訊號至第一電極陣列22與第二電極陣列23，而偵測觸碰面板 20，以得知至少一觸碰區域，接續偵測觸碰區域，以得知觸碰區域之至少一觸碰點，然而，由於經過所偵測觸碰面板2 0而得知的觸碰區域時可能會包含鬼點或是實際上並未觸碰的觸碰點，所以繼續針對該觸碰區域進行偵測，以找出觸碰區域中之實際的觸碰點，藉此提升掃描速度，並且透過偵測觸碰區域中之每一偵測點，以避免產生鬼點，進而達到觸碰面板的效率。In addition, another method for detecting a touch point of the capacitive touch panel 20 of the present invention is that the control unit 21 generates a scan signal through the first scan/detection bus 211 and the second scan/detection bus 212. Detecting the signal to the first electrode array 22 and the second electrode array 23, and detecting the touch panel 20 to learn at least one touch area, and continuously detecting the touch area to know at least one touch of the touch area Touch point, however, since the touch area that is detected by the detected touch panel 20 may contain a ghost point or a touch point that is not actually touched, continue to detect the touch area. Measure to find the actual touch point in the touch area, thereby increasing the scanning speed and detecting the efficiency of the touch panel by detecting each detection point in the touch area to avoid ghost points. .
