Description of the Invention: [Technical Field] The present invention relates to a touch panel, and more particularly to a touch panel having an improved electrode pattern. [Prior Art] - At present, the mainstream touch panels on the market are both resistive and capacitive. Among them, the resistance type is divided into the early four-wire resistive and five-wire resistive, six-wire or eight-wire resistive, and the capacitive φ is divided into a surface capacitive (Surface Capacitance Touch Screen, SCT) and a projected capacitive ( Projective Capacitance Touch Screen, PCT). Among them, the projected capacitive touch panel 'can be called digital touch technology' and the resistive and surface capacitive touch panels can be called analog analog touch technology. Traditional analog touch technology seeks to 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 make the resistance components around the edge occupy a small space, and it is required to achieve a more gradual edge level. The field, so that the accuracy of the touch panel is increased, the available range is larger.

Among them, the pattern of the _th, the series resistance bond is formed by the series electrode 4〇 connected in series on the conductive layer. The gap 44 is formed, and the spacing between the series electrodes 4〇 is §, which includes the outer portion of the |5 portion and the inner portion, such as the outer portion of the figure being 38 41, 43 etc. and the inner portion 201032098 being 42 The inner portion is formed by forming two insulating gaps 45 at every two gaps 44. One of the insulating gaps 45 is located at the gap 44, and the insulating gaps 45 are spaced apart by a discontinuous resistive section 46' which is slightly equal in length. The distance is S, and the equivalent resistance is as shown in Fig. 1B. In the pattern of Fig. 2A, the series resistance chain is formed by connecting series electrodes 48, 5〇 in series on the conductive layer to form a gap 54. Between 48, 50 The distance S is the outer portion and the inner portion, and the inner portion is taken in the manner of forming two insulating gaps 55 at each of the two gaps 54, each insulating gap 55 being located in the inner portion of the series electrode. And the interval between the insulating gaps 55 has a non-corresponding resistance section 56, the length of which is slightly equal 'the distance is s, and the equivalent resistance is as shown in the first twist diagram." Next, please refer to US Patent Publication No. 2006 No. /0119587, which discloses another improved electrode pattern, as shown in Fig. 3A, wherein the series resistance chain 145 is formed by connecting series electrodes 1〇5 in series on the conductive layer to form a gap 125, and the series electrode The outer portion 110 and the inner portion 彳15 are included, and the outer portion 110 forms a gap 12 与 with the inner portion 彳15. The inner portion is formed by forming two insulating gaps 130 at each of the two gaps 125.

Resistance segment 13 If the voltage of 5 is VN, VN+1, the electric island of the conductive island "o" can be averaged to (VN+VN+1)/2, and the equivalent circuit is shown in Fig. 3B. Although there are many manufacturers working 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 In view of the above problems in the prior art, the present invention proposes a touch panel 201032098 with an improved electrode pattern, voltage leveling provided by a discontinuous resistor chain, and voltage equalization provided by the homogenizing electrodes 'It can provide a very narrow side line routing space, and can also obtain excellent linear accuracy in any near-line edge area. The error value is another. The purpose is to provide a touch panel with an improved electrode pattern. By connecting the discontinuous resistor chain with the homogenizing electrode and the series electrode chain around the conductive layer, the narrowing of the frame portion is achieved, so that the touchable area in the same substrate area is increased, thereby improving Product flexibility with design. Φ In order to achieve the above object, the present invention provides a touch panel having an improved electrode pattern, comprising: a substrate, a conductive layer formed on the substrate, having an internal contact region, and a plurality of corner electrodes formed on the conductive layer a corner electrode, comprising a plurality of electrodes, formed at an edge of the conductive layer and connected to the limb electrodes, forming a rectangular electric field when the corner electrodes are applied with a voltage, each of the electrodes having a face An inner portion of the inner contact region, adjacent to the electrodes, has a gap-discontinuous resistor chain, and includes a plurality of discontinuous resistors formed on the conductive layer without a smooth-chain connection and a parallel period. The isolation and the internal-contacting region are formed by a plurality of first homogenizing electrode gaps formed at the edge of the internal contact region so that the discontinuous resistance key λ is adjacent to the edge of the internal contact region. The wheel of the non-connected resistor has a uniform voltage. In addition, the touch panel further includes a second homogenizing electrode chain formed by a plurality of second homogenizing electrodes spaced apart to form a space between each of the two first homogenizing electrodes to make the homogenizing electrode key The output voltage is more uniform. The length of the discontinuous shirt is calculated as Y=aX2+b, and a good compensation effect is obtained, so that the rectangular electric field is equalized, and the towel is made of the corner 6 201032098 electrode. The number is b, which is the experimental preset value, and a is calculated from a preset line segment maximum value Ymax. The maximum value of the line segment is determined by the length of the central electrode segment of the series electrode chain located at the two corner electrodes. . The plurality of discontinuous insulating segments forming the discontinuous resistor chain are intimately coupled to the inner portion of the series 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, which are sufficient to enable anyone skilled in the art to understand the technical contents of the present invention and to implement the present invention. The objects and advantages of the present invention are readily understood by those skilled in the art. [Embodiment] The present invention is a new design pattern and structure used in the detection of a capacitive touch panel, utilizing a small capacitance between a high-impedance transparent conductive film and a touch object (interval between a thick film and a transparent film) Material), the touch coordinates of the touch object can be accurately detected. When the resistive touch panel is detected, the touched position 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. 4, which is a layered view of the touch panel of the present invention, which includes a basic electrode frame layer 400, a conductive layer 300, and a substrate 200. Among them, the round shape of the electrode frame layer 4 can be printed on the conductive layer 3〇〇 by a screen printing process using an environmentally friendly lead-free high temperature silver paste. The silver metal is fused to the conductive layer 300 through a high temperature of 500 ° C or higher, and the conduction resistance value between the electrodes is extremely small (which can be regarded as a near zero resistance value). It has high resistance to changes in ambient temperature. In addition, after the silver wire and the conductive layer 300 are crystallized at a high temperature, the chemical resistance can be remarkably improved. In addition, other metals than silver wires, such as molybdenum/ming/key metal layers, chromium or other metals with better conductivity than 201032098, may also be used. In addition, the conductive layer 300 can be used with a higher resistance, so that it has less energy loss and less electric current. Structurally, the substrate 200 can be made of a glass substrate, and the conductive layer 300 can be formed by sputtering, and the pattern on the conductive layer can be generated by bribery or laser. Next, a high-temperature silver pattern is printed to form a high-temperature silver pattern. The electrode frame layer 400 〇 In addition, the substrate 200 can be made of other materials, such as a 'soft substrate, and the electrode pattern can be fabricated by a process suitable for a flexible substrate. - Next, please refer to FIG. 5, which is a structural view of the conductive layer 300 of the present invention, wherein the black © region is an insulating portion 311, 312, 313, 314 distributed around the conductive layer, and the X-axis is an insulating portion. 312, 314, the axial direction is the insulating portion 311, 313. The insulating portions 311, 312, 313, and 314 are formed by means of rice or laser, and the function thereof is to isolate the electrode layer of the electrode frame layer 4, and a conductive discontinuous resistance key is formed to form the conductive discontinuous resistance key. The average voltage level of each electrode outlet is 'to form a uniformly distributed equipotential electric field. Among them, the discontinuous resistance chain which is not engraved is calculated by the formula of Y = aX2 + b to form a non-uniformly distributed insulating portion as shown in Fig. 5. The detailed parameter acquisition method will be explained later. In addition, the four corners 321, 322, 323, 324 of the conductive layer 3 are the positions of the four corner electrodes. Next, please refer to FIG. 6 which is a structural diagram of the electrode frame layer 400 of the present invention, which includes four corner electrodes 411, 412, 413, 414, and a series electrode chain 420 connected in series with the four corner electrodes. Finally, There is also a set of electrode chains 430 which form a first separation distance (〇1) from the series electrode chain 42A. Wherein, in the embodiment of FIG. 6, the series electrode chain 42 is formed by overlapping a plurality of z-type electrodes to form an outer portion and an inner portion, and each electrode is formed with a fixed gap as a subsequent series connection. The space in which the resistor is formed. Thus, when the electrode frame layer 400 is formed on the conductive layer 300 of 201032098, the fixed gap between the electrodes of the series electrode chain 42A constitutes a competition resistance key, so that the voltage transmitted from the corner electrode provides a series voltage supply. The electrode chain 43 可 can then subdivide the voltage supplied by the series electrode chain 420 into a finer electrical distribution. The series resistance key can be other structures, such as S-type, fork type, continuous section, etc., so that continuous distribution of voltage can be achieved. The number of z-type electrodes in the series electrode chain 42〇, 'designed according to the size of the touch panel' Φ plate size from small to large, can be designed for each axis 3' 5' 7' 9' 11' 13 ' 15, 17, ... (2n + 1) 'n> 1 and other different numbers of electrodes. For example, the 6th > graph is an embodiment of nine 2-type electrodes. The central electrode segment is formed by reversing the z-type electrode and has a length of Ymax. From left to right, there are Υ1, γ2, γ3, γ4, γ5 electrodes, and so on. Since the input voltage of the series electrode chain is transmitted by the corner electrode, a pressure drop occurs at each of the Ζ-type electrodes via the series resistance chain. In order to provide an electric field distribution of the conductive layer 3, the present invention generates an uneven resistance through the unconnected resistance 产生 generated by the insulating portion 311 312313314 on the conductive layer 3, and is separated by a corner electrode. The closer the G is, the more basic the principle of giving greater resistance to design the resistance value of the discontinuous resistor chain. • Therefore, the voltage value transmitted through the series resistor chain will be compensated by the unmatched resistance key to form uniformity. Voltage supply. However, the value of the voltage 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 being different. Therefore, the present invention provides a design of the electrode chain 430 in addition to the design of the discontinuous resistor chain, so that the supply of voltage can be sufficiently uniformized. After the electrode frame layer 400 is formed on the conductive layer 300, the electrode chain 430 is disposed in the inner layer of the discontinuous resistance chain, that is, the discontinuous resistance chain is disposed between the series electrode key 420 and the electric pole 430. Therefore, after the voltage supply of the discontinuous resistor chain, and then the electric power added by the electrode key 4 is uniformized, the present invention can provide an excellent electric field uniformity _ control panel, and the error range is 1% after the measured result. Within. Figs. 4 to 6 are diagrams showing the electrode structure of the present invention as a whole. Next, the improved electrode pattern of the present invention will be described with a detailed structural view. '°month reference to Fig. 7' is a detailed structural view of the electrode frame layer 400 of Fig. 6. The figure shows the four Ζ-type electrodes', of which two are complete (the length of the plate is L1), and the two fragments are. 2: 〇 electrode 42G_Xn·1, 42Q-Xn, 42 called +1 ′ can provide Vw, νΝ, νΝ+1 electric grind distribution, and electrode chain 430 ij can provide a finer voltage distribution. The inner portion of the z-type electrode and the two-gap D1 ' formed by the electrode bond 々so are defined by the physical characteristics of the conductive layer 3〇〇, which is a discontinuous resistance chain required for formation, and therefore, the resistor The formula R = pL / A, the required 〇 1 value can be calculated. Let 'R be the resistance value at both ends of the wire, p be the conductivity of the wire, A be the cross-sectional area of the wire, and L is the length of the wire. Domain, this gap m is not in the shape of the resistor chain, which will be explained later. There is a horizontal gap 421 and a vertical interval 422 between the Z-type electrodes, so that a series resistor is formed between the Z-type electrodes, thereby forming a series resistance chain. The thickness of the z-type electrode is the same. The specific thickness design is customized according to the manufacturing technology. The thickness of the pole is as thin as possible, so as to reduce the size of the frame, so that the touchable area of the touch panel is larger. . The electrode chain 430 includes a first homogenizing electrode 431 and a second homogenizing electrode 432. Wherein, the length of the first-averaging electrode 431 is from 2, the thickness is T2, the width of the interval 434 is L5, and the first-averaging electrode 431 can be a -T-type structure, and the length of the bottom of the τ-type is It is preferred to be parallel to the second homogenizing electrode 432. The length of the second homogenizing electrode 432 is a port, and the distance between the first pole 431 and the second homogenizing electrode 432 is 433. Wherein, the preferred one is that the D-type bottom length L2A of the first homogenizing electrode 431 is equal to the length L3 of the second homogenizing electrode 432 (4) the T-shaped bottom edge of the homogenizing electrode 431 and the second edge of the second homogenizing electrode 432 The distance between the two is 2, the length of the second homogenizing electrode 2 is 2/3, and the remaining ratio can be as 1/5, 1Μ, 1/3, 1/2, 2, 2" ,. It can be determined by actual tests. It is best to achieve the best electric field uniformity. In the Ζ-type electrode surface of the Φ-electrode chain 420, a multi-turn homogenizing electrode 431 (constituting the first-average electrode chain) and a plurality of second homogenizing electrodes 432 having a homogenized electrode bond® are evenly distributed (construction The two-homogenized electrode chain) is as shown in Figure 7. When the electrode chain 430 is formed on the conductive layer 300, the 帛 homogenizing electrode chain is spaced apart from the second homogenizing electrode chain, and the milk 4 constitutes a resistive structure on the conductive layer 300. Since the first-averaged electrode chain and the second homogenized electrode bond are in a uniform distribution, the voltage transmitted through the Ζ-type electrode and then via the discontinuous resistance key can be made to be a humanized uniform. That is, the 'electrode chain 43' allows the electric field ultimately transmitted to the touch area of the conductive layer 3 (f) to be more evenly distributed. ® The number of the first-averaged electrode chain and the second-averaged electrode chain at the inner edge of the internal part of the Ζ-type electrode is different from the two groups in Figure 7, depending on the production technique. For example, It can be made into 3 groups, 4 groups, 5 groups...all. Such a configuration needs to be considered together with the design of the discontinuous resistance chain on the conductive layer 300. That is, the position of each of the first homogenizing electrodes 431 is disposed in a discontinuous resistance section as a voltage transfer. The second homogenizing electrode 432 can then perform a more detailed configuration of the voltage, for example, making a third homogenizing electrode and then homogenizing once. Then, please refer to FIG. 8 , which is the electrode frame layer 4 〇〇 formed on the conductive layer 3〇〇 2010-0398

As is clear from the figure, the non-corresponding resistor 331 is formed between the insulating portion 3U-type electrode and the first leveling electrode 1, and the resistance is formed by the conductive layer 300 to form the conduction portion of the z-type electrode. The discontinuous resistor 331 is seamlessly joined to the 2-type electrode and the first-averaged electrode. It can be clearly seen from the figure that the inner portion of each Z-shaped electrode has a segment of _ discontinuous resistor 331, and the $ core of the vertical portion of the z-shaped electrode corresponds to a segmental odor of discontinuous resistor 331 Yes, the first homogenizing electrode can be homogenized by the voltage of the discontinuous resistor such as the conduction z-type electrode, and then the voltage of the first homogenizing electrode 431 is further performed by the second homogenizing electrode 432. Secondary homogenization. Since the second homogenizing electrode 432 is arranged in parallel with the lower type bottom of the first grading electrode 431, the voltage of the first homogenizing electrode 431 and the second homogenizing electrode 432 can be uniformly output to the conductive layer 3〇. 〇上. In addition, since the discontinuous resistor chain provides different resistances to the z-type electrodes as voltage outlets for voltage compensation, the output voltage of each z-type electrode via the discontinuous resistor segments will be uniform. After the electric field of the electrode chain 430 is homogenized, a fairly uniform fringe electric field distribution can be obtained, which can effectively reduce the chopping effect of the fringe electric field. The length of the discontinuous resistor 331 is calculated according to the formula of 丫=Di 2 Get its length. The calculation method is as follows: 1X is the number of Z-type electrodes calculated from the corner electrodes. For example, starting from the corner electrode 411, there are xw, X2=2, X3=3, X4=4, X5=5, and 5 Z-types. electrode. 2_b is the preset value, which is obtained by experiment and statistics, and the best is between α3~2 q faces. 3. a is derived from 丫, and the size of Ymax can be determined by the length of the central electrode 429 above the sixth ridge. To the length of the financial power (four), take the large number of panels and the number of series electrode chains to evaluate. Ymax Wei shank electrode length is subtracted from left to right 12 201032098 01mm is the best β 4. From Ymax, b value and χ value, you can get a worth parameter. Thus, the length of 'I is calculated by Yn-1 = a(rv1)2+b, and the length of Υη is calculated as (8)2. The length of the intermediate Y between Yn 1 and Υη can be calculated in two ways: · Χ = (Χη-1 + Χη)/2, and then substituted into the formula; „• by γ=(γΜ+Υη)/ 2. The actual effect is the first type. Preferably, the optimum position of the discontinuous resistor 331 is the center of the vertical segment YC1 ® of the ζ-type electrode and the center of the inner portion YC2 (the center of the two vertical segments) Center), and the center of the first-average electrode corresponds to the center of the discontinuous resistor. Of course, some deviations in manufacturing, or 'non-central configuration at design time, are also available for the present invention. Moreover, it can achieve the effect desired by the present invention. In addition, in practice, the design of a plurality of discontinuous resistors can also be used in the inner portion of the z-type electrode. In other words, the present invention is applied to the series electrode chain. Between each electrode and the electrode, a discontinuous resistor is disposed, and the (four) portion of each electrode can also be configured with a non-connected ❹ resistor on the gamma. In addition, each discontinuous electrode can be configured with more than one - homogenizing the electrode, and between the first homogenizing electrodes, Having more than one second homogenizing electrode n discontinuous resistance, the number of the first homogenizing electrode or the second homogenizing electrode is configured to achieve the electric field homogenization problem to be solved by the present invention. The accuracy and cost are the main considerations. If the internal part of the electrode of each series electrode is designed with multiple discontinuous resistors, that is, the center of the vertical section of the two Z-type electrodes YC1 (if other electrode structures are used) , the internal portion of the electrode between the electrode and the electrode) is provided with a plurality of discontinuous resistors, and the length calculation of the continuous resistance of the 201032098 is not the same as the above two calculation methods. For example, two When the discontinuous resistor is disposed in the inner portion of the ζ-type electrode, it is preferably equidistantly disposed with the discontinuous resistors on both sides. For example, when between γη_1 and γη, respectively, Υ67, 丫(10) 33.

Among them, the former has a better effect. * Further, a discontinuous resistor obtained by a different calculation method can also be used in the present invention. Only by the first homogenizing electrode of the present invention, or by the combination of the first homogenizing electrode of the present invention and the second beta homogenizing electrode, a good uniform voltage distribution can be formed. The Ζ-type electrode is only one embodiment used in the present invention, and the shape of other different series electrode chains can also be used as an embodiment of the present invention. Since the principles are the same, they will not be described below. Thus, the resistance between the corner electrodes 411, 412, 413, 414 can be averaged by the pattern design of the electrode frame layer 400 and the conductive layer 300 of the present invention. Therefore, the voltage equipotential line of the X-axis can obtain an excellent parallel line distribution even at the edge of the line; similarly, the voltage equipotential line of the γ-axis can also obtain an excellent parallel line distribution. The embodiment of Fig. 8 illustrates that the insulating portion 311 constituting the discontinuous resistor 331 is formed between the inner portion of the series electrode chain 420 and the first series electrode chain 431, and the insulating portion 311 and the series electrode chain 420 and the A series electrode chain 431 is closely coupled to form a good insulating relationship. Such a structure 'effectively supplies the voltage of the Ζ-type electrode to the first series-connected electrode chain 431 accurately. However, at the time of production and manufacturing, variations in the process are inevitably caused, so that the insulating portion 311 is not accurately formed between the inner portion of the series electrode key 42A and the first series electrode chain 431. From the perspective of product use, these products can still be listed as good 201032098 if they can meet the requirements of customers. Please refer to Fig. 9 which is a second example of an enlarged view of the electrode frame layer 400 formed on the conductive layer 300. The insulating portion & 彳 of the discontinuous resistor 331 is formed between the inner portion of the series electrode chain 42A and the first series electrode chain 431, and the insulating portion 311 forms a pitch D1A with the series electrode chain 42〇, and A joint electrode chain 431 forms a pitch (10). This structure can still achieve an effective uniform distribution of electric fields.
