Description of the Invention: [Technical Field] The present invention relates to a touch panel, and more particularly to a touch panel having a sound-and-replacement electrode pattern. [Previous technology 4 Shu] At present, the mainstream touch panels on the market are both resistive and capacitive. Among them, the resistive type is divided into the early four-wire resistive and five-wire, six-wire or eight-wire resistive, and the capacitive type is divided into a surface capacitance touch screen (SCT) and a projected capacitive gas (Projective Capacitance Touch Screen). , PCT). Among them, the projected capacitive touch panel can also be called digital touch technology, and the resistive and surface capacitive touch panels can be called analog touch technology. Conventional analog touch technology does not establish a uniform equipotential electric field through the pattern configuration of resistive elements around the edges. With the continuous development of touch technology and the increasing requirements of related application products, how can the current technology reduce the space occupied by the resistive elements around the edge and require a more gentle edge equipotential field. The accuracy of the touch panel is increased and the available range is larger. Although many manufacturers have worked hard on the peripheral resistive element pattern of touch panels, there is still much room for improvement in improving the equipotential electric field of the edge electrodes. SUMMARY OF THE INVENTION There is a problem of the above-mentioned prior art. The present invention proposes a touch panel having a tuning-fork-type electrode pattern, the voltage leveling provided by the shirt, and the voltage uniform provided by the homogenizing electrode. It can provide very narrow side line traces, and can also make any near-line side 201122945 edge area with excellent linear accuracy, error value $1〇 / 0. Another object of the present invention is to provide a touch panel having an acoustic-type electrode pattern, comprising: a substrate, a conductive layer, a plurality of corner electrodes, and a series electrode chain. Wherein the conductive layer is formed on the substrate & has an internal contact region. Corner electrodes are formed at the corners of the conductive layer. The series electrode chain 'contains a plurality of sounds and my poles and a plurality of __, the edges of the heterogeneous conductive layer are connected with the corner electrodes to form a home electric field when the secret electrode is applied, and each electrode has an inner contact area. In one inner portion, there is a gap between adjacent tuning fork type electrodes. The present invention provides a touch panel having a sound-and-receiving electrode pattern, comprising a substrate, a conductive layer formed on the substrate and having an internal contact region; and a plurality of corner electrodes formed on the conductive layer a series of electrode electrodes, comprising a plurality of electrodes formed at an edge of the conductive layer and connected to the corner electrodes, wherein the corner electrodes are externally formed with an electric pie forming a moment, and each tilting electrode has a facing contact a region of the region, the adjacent ones of the electrodes have -_ discontinuous electricity, comprising a plurality of discontinuous resistors formed on the conductive layer, and the (four) electrodes are connected and formed in parallel, and formed Insulating the internal contact area; and ... the first-average electrode chain is formed by a plurality of first homogenizing electrode intervals formed on the edge of the discontinuous resistance key adjacent to the inner contact region to cause the output of the discontinuous resistor The voltage is uniformized. In the ploughing, the touch panel further includes a second homogenizing electrode chain formed by the plurality of nano-averaging electrodes to form a gap between each of the two first homogenizing electrodes to make the output of the homogenizing electrode chain The voltage is more uniform. The length of the discontinuous resistor is calculated by the equation of Y=aX2+b to obtain a good compensation effect to homogenize the dust lines generated by the rectangular electric field, wherein the lanthanide system is the electrode starting from the corner of the 201122945 electrode. The number is b, which is the preset value of the experiment. The a is the line of the pre-determined Wei segment. The maximum value is determined by the series electrode chain located at the central electrode segment of the two corner electrodes. The plurality of discontinuous insulating segments forming the discontinuous resistor chain are intimately coupled to the inner portion of the_electrode chain and the edge of the homogenizing electrode chain. The detailed features and advantages of the present invention are described in detail below in the embodiments, and the contents thereof are sufficient for the implementation of the contents disclosed in the specification, the scope of the patents and the scope of the patents disclosed herein. The related objects and advantages of the present invention will be readily understood by those skilled in the art. [Embodiment] The present invention is a new design pattern and structure, which is used in the detection of a capacitive touch panel, which utilizes a small capacitance between a high-impedance transparent conductive film and a touch object (interval between a thick film and a transparent film) Material)' can accurately detect the touch coordinates of the touch object. When the resistive touch panel is detected, the touched coordinates of the touch object can be accurately detected by using the voltage level detected by the touch object after touching the touch panel. First, please refer to FIG. 1 , which is a layered view of the touch panel 1 of the present invention, which includes a basic electrode frame layer 140 , a conductive layer 130 , and a substrate 12 . Structurally, the substrate 12 can be made of a glass substrate, and the conductive layer 13 is formed by sputtering, and the pattern on the conductive layer 130 is formed by etching or laser. Next, a 5Qcrc high temperature silver paste is printed to form the electrode frame layer 140. Further, the substrate 12 can be made of other materials, for example, a flexible substrate, and an electrode pattern can be formed by a process suitable for a flexible substrate. The material of the electrode frame layer may be selected from the group consisting of a silver wire, a molybdenum/ming/pin metal layer, and a chrome wire. 201122945 Next, please refer to Fig. 2, which is a structural view of the conductive layer 13Q of the present invention, in which the black region is the insulating portion 131 distributed around the conductive layer. The insulating portion 131 is formed by paste or laser. The function of the insulating layer 131 is to isolate the electrode layer of the electrode frame layer 14, and the discontinuous resistor chain is not inscribed as an insulating portion. The average voltage level of σ is derived to form a uniformly distributed equipotential electric field. Wherein, the length of the discontinuous resistive bond is not calculated, and the length is calculated by the formula Y=aX2+b to form an insulating portion such as a second non-uniform distribution, wherein the M Ymax domain of the resistor is not defined. The difference between the length of the remaining #'s discontinuous resistors. The detailed parameter acquisition method will be explained later. Further, at the four corners of the electrode frame layer 140, there are four corner electrode 141 positions. Next, please refer to FIG. 3 , which is a structural diagram of the electrode frame layer 14Q of the present invention, which includes four corner electrodes 141 ′ and a serial series electrode key with four corner electrodes, which is composed of a tuning fork type electrode 147 and a line type. The electrode 143 is constructed. Finally, there is a set of homogenizing electrode keys which form a first separation distance (D1) from the competing electrode keys, and are composed of the first homogenizing electrode 144 and the second homogenizing electrode 145. Wherein, in the embodiment of FIG. 3, the series electrode chain is formed by a plurality of acoustic-type electrodes 147 and the line electrode 143 forming a staggered cross-clip structure, and each of the electrodes is formed with a solid space. The gap is used as a space for the formation of a subsequent series resistor. Thus, when the electrode frame layer 14Q is formed on the conductive layer 130, the fixed gap between the acoustic electrode 147 of the series electrode chain constitutes a series resistance chain, so that the voltage transmitted from the corner electrode provides a voltage supply. The homogenizing electrode bond formed by the first homogenizing electrode 144 and the second homogenizing electrode 145 can further subdivide the voltage supplied by the series electrode chain into a finer voltage distribution. The number of electrodes of the in-line electrode 147 and the line electrode U3 of the series electrode chain can be designed according to the size of the touch panel. The panel size is from small to large, and can be designed as an electrode of different amounts in 201122945. For example, Fig. 3 is an embodiment of 16 tuning fork type electrodes 147. Since the input voltage of the series electrode chain is transmitted by the corner electrode 141 to form a voltage drop at each electrode via the series resistance chain, in order to provide a uniform electric field distribution of the conductive layer, the present invention transmits The discontinuous resistance bond generated by the insulating portion 131 on the conductive layer 13Q generates uneven resistance, and is designed to give a larger resistance by being closer to the corner electrode; the resistance electric kettle. Therefore, the voltage value transmitted by the shaft (four) resistance key will be compensated by the discontinuous resistance chain to form the supply voltage of the uniform sentence. However, the voltage value supplied by the discontinuous resistor chain may result in poor edge distribution of the voltage distribution due to the length of the resistor segment of the discontinuous resistor chain. Therefore, the present invention provides a design of the homogenizing electrode chain formed by the first-averaging electrode 144 and the second homogenizing electrode 145, so that the voltage supply can be sufficiently uniform. Chemical. The homogenizing electrode chain is disposed in the inner layer of the discontinuous resistance chain when the electrode frame layer 140 is formed on the conductive layer 13, that is, the discontinuous resistance chain is disposed between the series electrode chain and the homogenizing electrode chain. Therefore, after the voltage supply of the discontinuous resistor chain and the voltage of the homogenizing electrode chain are uniformized, the present invention can provide a touch panel with an excellent electric field uniformity, and the error range of the measured result is less than 1%. . Fig. 3 is a view showing the structure of the electrode of the present invention in a unitary structure. Next, the acoustic-type electrode pattern of the present invention will be described with a detailed structural view. Next, please refer to FIGS. 4A and 4B, which are enlarged views of a partial area of FIG. 3. Five tuning-fork electrodes 147 are shown. Sound-type electrodes 147-Xn_2, 147-X^, 147-Xn, 147〇 (n+1 and 147-Xn+2 and linear electrodes 143-Xn_2, 143-χ^, 143% and 143·Χη+ι respectively A voltage distribution of VN-2, VN_1, VN, VN+1, and VN+2 can be provided, and a uniform electrode bond can provide a finer voltage distribution, wherein the 4A circle is only the first homogenizing electrode 144. The embodiment, and the 201122945 4B diagram is an embodiment in which the first homogenizing electrode 144 and the second homogenizing electrode 145 are used. The acoustic re-type electrode 147 is composed of a re-shaped portion and a linear portion, and each of the acoustic-type electrodes The fork portion of 147 has a gap to accommodate the linear portion of the other tuning-fork electrode 147 to form a three-layer electrode structure 'and constitutes the gaps D1 and D2. The inner portion and the first-homogenization of the re-shaped portion of the acoustic-type electrode 147 The electrode 144 forms a gap D3 which is defined by the physical characteristics of the end conductive layer 13A, which is a space for forming a required discontinuous resistance chain. From the resistance formula R=pL/A, the required D3 can be calculated. Value, where R is the resistance value of the two ends of the wire, p is the conductivity of the wire, a is the cross-sectional area of the wire, and L is the length of the wire. The vertical portion of the electrode 147 is spaced apart by a distance D. The length of the tuning fork electrode 147 is L1. The tuning fork electrode 147 has a horizontal interval 146 therebetween, so that a series a electric connection is formed between the tuning fork type electrodes μ, thereby forming a series resistance chain. The length of the linear portion of the acoustic-type electrode 147 is L2, which is approximately the same as the length of the fork-shaped portion. The thickness of the acoustic-type electrode 147 is the county T1, and the specific thickness design depends on the manufacturing technology. In principle, the sound is again The smaller the thickness T1 of the electrode 147, the better, so as to reduce the size of the frame, so that the touchable area of the touch panel is larger. The Lu averaged electrode chain includes the first-average electrode 144 and the second leveling electrode 145. The length of the first-averaging electrode 144 is L3, the thickness is 2, the interval between the two first-averaging electrodes 144 is L4, and the first-averaging electrode 144 can be a _-type structure, and the τ-part The length is L5, and the thickness is preferably parallel to the bottom surface of the second homogenizing electrode 145. The length of the second homogenizing electrode 145 is L6, and the interval between the first homogenizing electrode 144 and the second homogenizing electrode 145 is D4. Wherein, the T-shaped bottom length L5 of the first-averaging electrode 144 may be equal to the first The length π of the homogenizing electrode 145, and the gap distance L7 formed by the bottom edge of the τ-type of the first-averaging electrode 144 and the edge of the second homogenizing electrode 145, for example, the gap distance L7 is the second homogenizing electrode 145 Length (10), 9 201122945 The remaining ratio can also be, such as 1/5, 1/4, 1/3, 1/2| 2/5 2/7 3/5, π 4/5. Corresponding to each series electrode The acoustic-type electrode 147 has an average distribution of at least the --electrode 144 (constituting the first-averaged electrode bond) and at least one second-homogenized electrode (the ==-averaged electrode bond)' as shown in Fig. 4B. When the first and second homogenizing electrode chains are formed on the conductive layer, the interval between the first homogenizing electrode chain and the second homogenizing electrode bond constitutes a resistive structure on the conductive layer. Since the first-averaged electrode bond and the second homogenized electrode bond are evenly distributed, the sub-I can be made even if the surface voltage is transmitted through the sound and the continuous transfer of the surface voltage. The homogenizing electrode chain allows the electric field that is ultimately transmitted to the conductive layer to be more evenly distributed. The number of the first homogenizing electrode key and the second homogenizing electrode key of the inner portion of each of the acoustic-type electrodes 147 is different from that of the 4B _ 2 group, and can be made by different production methods, for example, 'can be made It can be 1 group, 3 groups, 4 groups, 5 groups...all. With such a configuration, it is necessary to simultaneously design the design of the discontinuous resistance chain on the conductive layer 130. That is, at least one discontinuous resistor 133 is disposed at each of the positions of the first-averaging electrodes 144 as a medium for voltage transfer. The second homogenizing electrode 145 can then make the voltage more sensitive, for example, making a third homogenizing electrode and then homogenizing once. Next, in FIG. 4B, a discontinuous resistor 133 is formed between the insulating portion 131, the acoustic-type electrode 147, and the first-averaging electrode 144. 'The insulating portion 131 is formed by the conductive layer 13〇# to form a resistor. Further, a conduction portion with the tuning-fork type electrode M7 is formed, and the discontinuous resistor us is seamlessly joined to the acoustic-type electrode and the first homogenizing electrode. As is clear from the figure, the inner portion of each of the acoustic-type electrodes 147 has two insulating portions 131, that is, a configuration of two discontinuous resistors 133; and the center of the vertical portion of the tuning-fork-shaped electrode 147 is Corresponding to a segment that does not connect the 201122945 continuous resistor 133, it also corresponds to the center of the first homogenizing electrode 144. Then, the first homogenizing electrode 144 can conduct the sound and shape the electrode 147 (four) by the discontinuous resistor 133 and homogenize, and then carry on the voltage of the first homogenizing electrode 144 by the second homogenizing electrode 145. Secondary homogenization. Since the second homogenizing electrode 145 is arranged in parallel with the τ-type bottom of the first homogenizing electrode 144, the voltage of the first homogenizing electrode 144 can be uniformly outputted to the conductive layer 130 with the voltage of the second homogenizing electrode 145. . In addition, since the discontinuous resistor chain provides different resistances to the tone-type electrode 147 as the voltage ® Α σ as a voltage compensation', then the output voltage of each of the tone-type electrodes w through the continuous resistor 133 will be. After homogenization of the electric field of the homogenizing electrode chain, the fringe electric field distribution of the equivalent mean sentence can be obtained, and the chopping effect of the fringe electric field can be effectively reduced. Here, the length of the discontinuous resistor 133 can be calculated according to the formula of Y = aX2 + b, and the discontinuous resistor 133 is formed as the insulating portion 131. The calculation method will be described as follows: 1. The X system is the number of electrodes of the acoustic-type electrode 147 which is calculated from the corner electrode. For example, starting from the corner electrode 141, there are a total of 16 tuning-fork electrodes 147. • 2· b is the preset value 'which is obtained by experiment and statistics' and the best is between ~ 3~4 〇mm. 3. a is calculated from the length Ymax of the central section of the discontinuous resistor. Please refer to Fig. 2, and the size of Ymax is evaluated by the size of the panel and the number of series electrode chains. 4_ by Ymax, b value and X value, you can get the parameter of a value. Thus, the length of Υη·ι is calculated as Yn^am-I )2+b; the length of Υπ is calculated as Yn=a(n)2+b. The length of Yn〇s between γη·1 and Υη can be calculated in two ways: Ι·Χ=(Χη·ι+Χη)/2 'Substituting into the formula; 丨丨·with γ=( Γη.ι+γη)/2. The actual effect can be placed in the center 1 of the vertical section of the acoustic-type electrode 147 and therein by the position of the discontinuous resistor 133. The center of the p portion is YC2 (the center of the center of the two vertical segments), and the middle of the first homogenizing electrode 144 corresponds to the center of the discontinuous resistor 133. Of course, the two deviations produced in manufacturing or the configuration of the non-Rolling Heart at the time of design are also provided by the present invention, which can achieve the desired effect of the present invention. In addition, in practice, the inner portion of the acoustic-type electrode 147 can also be used to distribute a plurality of discontinuous resistors 133 $ sigh. In other words, the present invention can be configured with more than one discontinuous resistor 133 in the inner portion of each of the acoustic electrodes 147 of the series electrode chain. In addition, each of the φ-type electrodes 147 may be configured with at least one first leveling electrode 144, and between the first leveling electrodes 144, at least _ second leveling electrodes 145 may be disposed. That is, the number of the discontinuous resistors 133, the first leveling electrode 144 or the second leveling electrode 145 is configured to achieve the problem of the present invention to solve the problem of electric field, which can be achieved by the precision of the production equipment. And cost is the main consideration. The inner portion of the electrode of each series electrode is designed with a plurality of discontinuous resistances I%, that is, at the center of the vertical section of the two acoustic-type electrodes 147 (if other electrode holders are used, A plurality of discontinuous resistors are disposed for the inner portion of the electrode between the electrode and the electrode, and the length of the discontinuous resistor 133 disposed therebetween can be calculated by the above two calculation methods. For example, when the two non-continuous resistors are disposed in the inner portion of the acoustic-type electrode 1彳7, it is preferably a fine-side auxiliary resistor 133, such as a knife between (1) and (1). Don't be Υη々67, Υη. feather. And Y_7=a(n 〇 67)2+b, to 丫. 〇33=a(n 〇33)2+b ; or 丫咕(四)丫^+丫^(10) with Yn 〇33=(Yn n+nw. In addition, the discontinuous resistance obtained by different calculation methods can also be used. In the present invention, only 12 201122945, through the first homogenizing electrode 144 of the present invention, or through the combination of the first homogenizing electrode 144 of the present invention and the second homogenizing electrode 145, a good uniform voltage distribution can be formed. Therefore, through the pattern design of the electrode frame layer 140 and the conductive layer 130 of the present invention, the voltage value between the corner electrodes 141 can be averaged. Therefore, the voltage equipotential line of the axial direction can be obtained even at the near-line edge. Excellent parallel line distribution; similarly, the voltage equipotential lines in the γ-axis can also be excellent in parallel line distribution. In the embodiment of the fourth embodiment, the insulating portion 131 constituting the discontinuous resistor 133 is formed between the inner portion of the acoustic-type electrode 147 and the first-averaging electrode 144, and the insulating portion 131 and the tuning-fork electrode 147 are formed. The first homogenizing electrode 144 is closely coupled to form a good insulating relationship. Such a structure 'effectively supplies the voltage of the acoustic-type electrode 147 to the first leveling electrode 144 accurately. However, at the time of production and manufacturing, variations in the process are inevitably caused, so that the insulating portion 131 is not accurately formed between the inner portion of the tuning fork type electrode 147 and the first leveling electrode 144. From the perspective of product use, these products can still be classified as good if they meet the requirements of customers. * Refer to Fig. 4C, which is a third example of an enlarged circle in which the electrode frame layer 14 is formed on the conductive layer 13A. The insulating portion 131 of the discontinuous resistor 133 is formed between the inner portion of the acoustic-type electrode 147 and the first leveling electrode 144, and the insulating portion 131 forms a pitch D1A ' with the tuning-fork electrode 147 and is homogenized with the first The electrodes 144 form a pitch D1B. This structure still achieves an effective uniform distribution of the electric field. The design of the first homogenizing electrode 144, the second homogenizing electrode 145, and the discontinuous resistor 133 is the same as that of the fourth and fourth embodiments, and will not be described again. In effect, a tuning fork type electrode 147 can be equivalent to two tuning fork type electrodes 47.
