First, please refer to FIG. 1 , which is a layered view of the touch panel 100 of the present invention, which includes a basic electrode frame layer 140 , a conductive layer 130 , and a substrate 120 . Structurally, the substrate 120 may be a glass substrate, and the conductive layer 130 may be formed by sputtering, and the pattern on the conductive layer 130 may be formed by etching or laser. Next, a 500 ° C high temperature silver paste pattern is printed to form the electrode frame layer 140. Further, the substrate 120 may be formed of other materials, for example, a flexible substrate, and an electrode pattern may 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/aluminum/molybdenum metal layer, and a chrome wire.

Next, please refer to FIG. 2, which is a structural diagram of the conductive layer 130 of the present invention, wherein the black region is the insulating portion 131 distributed around the conductive layer. The insulating portion 131 is formed by etching or laser, and functions to isolate the electrode layer of the electrode frame layer 140. If not etched into an insulating portion, a conductive discontinuous resistance chain is formed to form each electrode output. The average voltage level of the port to form a uniformly distributed equipotential electric field. Wherein, the length of the discontinuous resistance chain that is not etched is calculated by the formula of Y=aX ² +b to form a non-uniformly distributed insulating portion as shown in FIG. 2, wherein the length Ymax of the central portion of the discontinuous resistor It is pre-defined and determines the length of the remaining 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 an external view of the electrode frame layer 140 of the present invention, which includes four corner electrodes 141, and a series electrode chain connected in series with the four corner electrodes, which is composed of a tuning fork type electrode 147 and The linear electrode 143 is constructed. Finally, there is a set of homogenizing electrode chains forming a first gap (D1) with the series electrode chain, which is composed of the first homogenizing electrode 144 and the second homogenizing electrode 145. In the embodiment of FIG. 3, the series electrode chain is formed by a plurality of tuning-fork electrodes 147 and a linear electrode 143 formed in a staggered cross-clip structure, and each electrode is formed with a fixed gap as a Subsequent formation of a series resistor. Then, when the electrode frame layer 140 is formed on the conductive layer 130, the fixed gap between the tuning-fork electrodes 147 of the series electrode chain constitutes a series resistance chain, so that the voltage transmitted from the corner electrode provides a series voltage supply. The homogenized electrode chain 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 tuning fork type electrode 147 and the line type electrode 143 of the series electrode chain can be designed according to the size of the touch panel, and the panel size is from small to large, and can be designed for each axially different quantity. Electrode. 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, a phenomenon of voltage drop is formed at each electrode after passing through the series resistance chain. In order to provide a uniform electric field distribution of the conductive layer 130, the present invention generates a non-uniform resistance through a discontinuous resistance chain generated by the insulating portion 131 on the conductive layer 130, and the closer the distance is to the corner electrode, the larger the giving The basic principle of resistance is to design the resistance value of the discontinuous resistor chain. Thus, the value of the voltage delivered via the series resistor chain will be compensated by the discontinuous resistor chain to form a uniform supply voltage.

However, the voltage value supplied by the discontinuous resistor chain may result in poor edge margin of the voltage distribution due to the different lengths of the resistor segments of the discontinuous resistor chain. Therefore, in addition to the design of the discontinuous resistance chain, the present invention further provides a design of the homogenizing electrode chain formed by the first homogenizing electrode 144 and the second homogenizing electrode 145, so that the voltage supply can be sufficiently uniformized. . When the electrode frame layer 140 is formed on the conductive layer 130, the homogenization electrode chain is disposed in the inner layer of the discontinuous resistance chain, that is, the discontinuous resistance chain is disposed between the series electrode chain and the homogenization 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 an electrode structure of the present invention in an overall structure. Next, the tuning fork type electrode pattern of the present invention will be described in 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 type electrodes 147 are illustrated. Tuning fork type electrodes 147-X _n-2 , 147-X _n-1 , 147-X _n , 147-X _n+1 and 147-X _n+2 and linear electrodes 143-X _n-2 , 143-X _{n- 1} , 143-X _n and 143-X _n+1 provide voltage distributions of V _N-2 , V _N-1 , V _N , V _N+1 and V _N+2 , respectively, and the homogenization electrode chain can provide more Fine voltage distribution. 4A is an embodiment in which only the first homogenizing electrode 144 is used, and FIG. 4B is an embodiment in which the first homogenizing electrode 144 and the second homogenizing electrode 145 are employed.

The tuning fork electrode 147 is composed of a fork portion and a linear portion, and the fork portion of each tuning fork electrode 147 has a gap (first gap) for accommodating the linear portion of the other tuning fork electrode 147 to form a three-layer electrode. Structure, and constitutes gap D1 (second gap) and D2 (third gap). As shown in FIG. 4A, the fork portion has a U-shape, and is formed by connecting one end of a vertical portion to one end of the upper line portion and one end of the lower line portion, wherein the length of the upper line portion and the lower line portion are formed by both ends of a vertical portion. Equal to each other and perpendicular to the vertical portion, both the upper linear portion and the lower linear portion constitute a first gap, and the vertical portion of the U-shaped portion constitutes a vertical portion of the tuning fork type electrode 147. On the other hand, one end of the linear portion of the tuning-fork type electrode 147 is vertically connected to the center of the vertical portion of the fork-shaped portion and is parallel to the upper-line portion and the lower-line portion, thereby constituting a structure such as a tuning fork. The inner portion of the fork portion of the tuning fork type electrode 147 forms a gap D3 (fourth gap) with the first leveling electrode 144, which is defined by the physical characteristics of the conductive layer 130, which is a discontinuous resistance chain required for formation. The space, by the formula of the resistance R = ρL / A, can calculate the required D3 value. Where R is the resistance value at both ends of the wire, ρ is the conductivity of the wire, A is the cross-sectional area of the wire, and L is the length of the wire.

The gap of the vertical portion of the tuning fork type electrode 147 is D5. The tuning fork type electrode 147 has a length L1, and the tuning fork type electrode 147 has a horizontal gap 146 therebetween, so that a series resistor is formed between the tuning fork type electrodes 147, thereby forming a series resistance chain. The length of the linear portion of the tuning fork electrode 147 is L2, which is approximately the same as the length of the fork portion. The thickness of the tuning fork electrode 147 is T1, and the specific thickness design depends on the manufacturing technology. In principle, the smaller the thickness T1 of the tuning fork 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 homogenizing electrode chain includes a first homogenizing electrode 144 and a second homogenizing electrode 145. The first homogenizing electrode 144 has a length L3 and a thickness T2, and is between the two first homogenizing electrodes 144. The gap is L4, and the first homogenizing electrode 144 may be a T-shaped structure having a T-shaped bottom having a length L5 and a thickness parallel to the bottom surface of the second homogenizing electrode 145. The length of the second homogenizing electrode 145 is L6, and the gap between the first homogenizing electrode 144 and the second homogenizing electrode 145 is D4. The T-type bottom length L5 of the first homogenizing electrode 144 may be equal to the length L6 of the second homogenizing electrode 145, and the T-shaped bottom edge of the first homogenizing electrode 144 and the edge of the second homogenizing electrode 145 are formed. The gap L7, for example, the gap L7 is 2/3 of the length of the second homogenizing electrode 145, and the remaining ratios may be, for example, 1/5, 1/4, 1/3, 1/2, 2/5, 2 /7,3/5,3/7,4/5,...

The tuning fork type electrode 147 corresponding to each series electrode chain is evenly distributed with at least one first leveling electrode 144 (constituting the first leveling electrode chain) and at least one second leveling electrode 145 (constituting the second leveling electrode chain) , as shown in Figure 4B. When the first and second homogenizing electrode chains are formed on the conductive layer 130, the spacing between the first homogenizing electrode chain and the second homogenizing electrode chain constitutes a resistive structure on the conductive layer 130. Since the first homogenizing electrode chain and the second homogenizing electrode chain are evenly distributed, the voltage transmitted via the tuning fork type electrode and then via the discontinuous resistance chain can be uniformly distributed. That is, the homogenization of the electrode chain allows the electric field ultimately transmitted to the touch area of the conductive layer 130 to be more evenly distributed.

The number of the first homogenizing electrode chain and the second homogenizing electrode chain of the inner edge of the inner portion of each tuning-fork electrode 147 can be made in different numbers according to the production skill, in addition to the two groups in FIG. 4B, for example, It can be made into one group, three groups, four groups, five groups...all. Such a configuration needs to be considered together with the design of the discontinuous resistor chain on the conductive layer 130. That is, each of the first leveling electrodes 144 is disposed with at least one discontinuous resistor 133 as a medium for voltage transfer. The second homogenizing electrode 145 can then perform a more detailed configuration of the voltage, for example, making a third homogenizing electrode and then homogenizing once.

Next, in FIG. 4B, the discontinuous resistor 133 is formed between the insulating portion 131, the tuning fork electrode 147 and the first leveling electrode 144, and the insulating portion 131 is etched by the conductive layer 130 to form a resistor, which is also formed. The conduction portion of the tuning-fork electrode 147 is seamlessly joined between the discontinuous resistor 133 and the tuning-fork electrode and the first homogenizing electrode. As is clear from the figure, the inner portion of each tuning-fork type electrode 147 has two insulating portions 131, that is, a configuration of two discontinuous resistors 133; and the center of the vertical section of the tuning-fork-shaped electrode 147 corresponds to There is a section of discontinuous resistor 133 that simultaneously corresponds to the center of the first homogenizing electrode 144. Then, the first homogenizing electrode 144 can conduct and homogenize the voltage of the tuning fork electrode 147 by the discontinuous resistor 133, and then re-energize 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 T-shaped 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 tuning fork electrode 147 as a voltage outlet as a voltage compensation, the output voltage of each tuning fork electrode 147 via the discontinuous resistor 133 will be uniform. After homogenization of the electric field of the homogenizing electrode chain, a fairly uniform fringe electric field distribution can be obtained, which can effectively reduce the chopping effect of the fringe electric field.

Here, the length of the discontinuous resistor 133 can be calculated according to the formula of Y=aX ² +b, and the discontinuous resistor 133 is formed as the insulating portion 131. The calculation method is as follows:

1. X is the number of electrodes of the tuning fork 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 type electrodes 147.

2. b is the preset value, which is obtained by experiment and statistics. The best one is between 0.3~4.0mm.

3. a is calculated from the length Ymax of the central section of the discontinuous resistor. Please refer to Figure 2, The size of Ymax is estimated by the size of the panel and the number of series electrode chains.

4. From Ymax, b value and X value, the parameter of a value can be obtained.

Thus, Y _n-1 length to _{Y n-1 = a (n} -1) 2 + b calculated sum; length Y _n to ^{_{Y n = a (n) 2}} + b calculated sum. The length of Y _n-0.5 between Y _n-1 and Y _n can be calculated in two ways: I. X = (X _n-1 + X _n )/2, and then substituted into the formula; II. Y = (Y _n-1 + Y _n )/2. The actual effect is better in the first form.

Wherein, the position of the discontinuous resistor 133 can be placed at the center YC1 of the vertical section of the tuning fork type electrode 147 and the center YC2 of the inner portion thereof (the center of the center of the two vertical segments), and the center of the first leveling electrode 144 corresponds to no The center of the continuous resistor 133 is sufficient. Of course, some deviations in manufacturing, or non-central configuration at the time of design, are also available to the present invention, all of which achieve the desired effects of the present invention.

Further, in practice, a design in which a plurality of discontinuous resistors 133 are distributed to the inner portion of the tuning fork type electrode 147 may be employed. In other words, the present invention is applied to the inner portion of each tuning-fork electrode 147 of the series electrode chain, and more than one discontinuous resistor 133 may be disposed. In addition, each tuning fork type electrode 147 may be configured with at least one first leveling electrode 144, and between the first leveling electrodes 144, at least one second leveling electrode 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 electric field homogenization to be solved by the present invention, and the accuracy of the production equipment can be achieved. And cost is the main consideration.

If the inner portion of the electrode of each series electrode is designed with a plurality of discontinuous resistors 133, that is, at the center YC1 of the vertical segment of the two tuning fork electrodes 147 (if other electrode structures are used, the electrodes are between the electrodes The inner portion of the electrode is provided with a plurality of discontinuous resistors 133, and the length of the discontinuous resistor 133 disposed therebetween is calculated by the above two calculation methods. For example, when two discontinuous resistors are disposed on the inner portion of the tuning fork electrode 147, it is preferably disposed equidistantly with the discontinuous resistors 133 on both sides, such as between Y _n-1 and Y _n . They are Y _n-0.67 and Y _{n-0.33 respectively} . And Y _n-0.67 = a(n-0.67) ² +b, with Y _n-0.33 = a(n-0.33) ² +b; or, Y _n-0.67 = (Y _n-1 ^* 2+Y _n ^* 1) / 3 is Y _{n - 0.33} = (Y _n-1 ^* 1 + Y _n ^* 2) / 3.

Further, discontinuous resistors obtained by different calculation methods can also be used in the present invention. A good uniform voltage distribution can be formed by the first homogenizing electrode 144 of the present invention or by the combination of the first homogenizing electrode 144 and the second homogenizing electrode 145 of the present invention.

Thus, the voltage value between the corner electrodes 141 can be averaged by the pattern design of the electrode frame layer 140 and the conductive layer 130 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 Y-axis can also obtain an excellent parallel line distribution.

In the embodiment of FIG. 4B, the insulating portion 131 constituting the discontinuous resistor 133 is formed between the inner portion of the tuning fork electrode 147 and the first homogenizing electrode 144, and the insulating portion 131 and the tuning fork electrode 147 and the A homogenizing electrode 144 is closely coupled to form a good insulating relationship. With such a configuration, the voltage of the tuning fork type electrode 147 can be efficiently supplied to the first leveling electrode 144.

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.

Please refer to FIG. 4C , which is a third example of an enlarged view of the electrode frame layer 140 formed on the conductive layer 130 . The insulating portion 131 of the discontinuous resistor 133 is formed inside the tuning fork electrode 147 Between the portion and the first homogenizing electrode 144, the insulating portion 131 forms a gap D1A with the tuning fork electrode 147 and forms a gap D1B with the first homogenizing electrode 144. This structure can still achieve an effective electric field uniform distribution.

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, one tuning fork electrode 147 can be equivalent to two tuning fork electrodes 147.
