Invention Explanation (What) The electrode is made of low-resistance metal in the X-axis direction, and it is arranged between two wires on both sides of the transparent conductive film of the second substrate, so an active area made of high-resistance metal is formed therein. A dot-shaped space separating device made of an insulating material is formed between the two bases for electrical isolation, and is formed in an active area defined by an area between the X-axis potential compensation electrodes. On the other hand, after the formation of the processing insulator, the potential compensation electrode in the y-axis direction is made of a low-resistance metal in the y-axis direction, which is arranged between two wires on both sides of the transparent conductive film of the first substrate. Therefore, an active region made of the same resistance metal is formed therein. In operation, in order to detect the X-axis chirp, when a potential is applied to the first substrate, it is distributed over the entire surface of the transparent conductive film. At this time, when the user applies pressure with a finger or a pen on the touch curtain (or curtain), the upper and lower substrates (the first and second substrates) are in contact with each other, and the second substrate is opposite to the second substrate. The potential of the phase is induced at this point, and the x_axis 値 is calculated from the induced signal. When the lower and upper base farts are in contact with each other, the potential is also applied to the second substrate, so it is distributed over the entire surface of the transparent conductive film. The y-axis potential at the point where a finger or pen exerts pressure is sensed on the first substrate. The shaft axis is also calculated from the sensed signal. Therefore, the x / y coordinates 値 can be displayed on the second display. Figure 1 shows the electrode structure of a conventional 4-wire resistive touch screen. Because the linearity of the electrode is related to the distortion of the signal, the linearity of the electrode is an important item in electrode quality control. In order to provide a uniform potential field perpendicular to the I direction of the signal application, as shown in the figure, those low-resistance metal potential compensation electrodes are suitable for this paper. China National Standard (CNS) A4 specification (210 X 297 with love) 519613 B7 V. Description of invention (3) (Please read the note on the back? Matters before filling out this page) 40a, 40b are perpendicular to the signal application direction It is mounted on transparent electrodes 30 made of high-resistance metal and parallel to each other. In order to check whether the touch screen made of the upper and lower substrates 10 is properly operated, those electrodes are checked by measuring the linear level method. The test method is to apply an operation voltage to the electrode 20, and then measure the difference between the solid distributed potential on the transparent electrode 触控 of the touch screen and the estimated distributed potential. If the measurement volume also exceeds or fails to those predetermined standards, position information errors will be generated. In this way it can be seen as a distortion of the signal. As a result, the linear level measurement of electrode 20 is equivalent to checking whether the touch screen is good or inferior. The clothing produced by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Linear measurement method of the electrode on the substrate. If the left and right end points of the X-axis potential compensation electrode are respectively connected to the power supply and the ground, a uniform potential field perpendicular to the signal application direction is formed on the transparent electrode 30. At this time, if the potential of the contact point on the upper substrate 10 passes through the point touched by the pen, it is caused by the contact between the upper substrate 10 and the transparent electrode 3 〇 of the lower substrate 10. The resistance is transferred to a relatively low substrate 10. Then, the voltage across the resistor RD, which was thought to be measured, is measured, so the potential sensed to the lower substrate 10 can be detected, and the resistor RD is connected to the potential compensation electrodes 40a, 40b on the lower electrode 10. Between an end point and ground. In addition, the conditions of RD > RC should be satisfied, so the potential of almost all contact points on the upper substrate 10 can be induced at the two ends of RD. The measured potentials are plotted in a graph in Figure 3. The linear error is displayed as a percentage, which is printed by using the ideal paper size in Figure 3 to apply the Chinese National Standard (CNTS) A4 specification (210 X 297 mm) 519613 Printed by the Consumers ’Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 5.

Thus, the linear error at a certain point is calculated as the error VDIFF at this point and the relative magnitude of the voltage difference between νχ 1 and VX2. This calculation method is also applicable to the direction of the plant axis. When the position information of the finger or pen is displayed on the screen, the error caused by the linearity of the electrode will make the position information incorrect. For this reason, errors can be used as a criterion for the difference between good and inferior products. Even if the product has miniaturization, ultra-thinning, and stable driving capability, it is necessary to design it. • The package linearity is more important than other factors, because it is directly related to the error of the position information.

Description of the Invention (ί) Examples. Here, as shown in FIG. 5, those potential-compensating electrodes 40 a and 40 b made of low-resistance metal are arranged in series with those low-resistance elements and are arranged perpendicular to the signal application direction, and the transparent electrode 30 is arranged to Indicate flat resistance, which arranges those resistive elements into a matrix type. In addition, those potential compensation electrodes 40a, 40b and the transparent electrode 30 are electrically coupled together through a contact resistance element RC. Theoretically, the contact resistance means should not exist in the transparent electrode 30 and those potential compensation electrodes 40, 4J) b. However, when the potential distribution on the touch screen actually manufactured is measured, the contact resistance exists on the touch screen, so it has a certain influence on the potential distribution. It is considered to be due to the difference in materials between those potential compensation electrodes and the transparent electrode 30. Therefore, it is necessary to resolve the problem based on a detailed breakdown of the materials used. However, the current state of the touch screen has been set based on the assumption that the contact resistance exists. The problems and disadvantages of the potential compensation electrodes 40a, _ can be determined by the linear and equivalent potential distribution of the electrode 20 And be understood. When a signal is applied to the touch screen, Figure 6 shows an equivalent circuit of the electrode. Figure 7 shows the potential divisions according to those at the Η = position in Figure 6. In order to get accurate position information, the potential cloth should! The ideal potential-sample is formed vertically in the signal application direction.

When the touch screen is added to a flat display, it will inevitably occur. For example, when 1 ^ < :: 1) The display needs to be satisfactorily miniaturized and thin. When the touch screen is added, those electrodes should be designed in, for example, the LCD (that is, the area between the viewing area and the outer circumference of the glass). ) Is formed in a narrow region of the edge region, so the width of the electrode becomes smaller, and finally the resistance 値 becomes larger. Then, this causes a linearity error of the electrode, and a second-class touch screen is generated. Because low The resistance 値 of the potential compensating electrode made of resistance metal and the resistance 透明 of the transparent electrode are not very similar, and the potential distribution according to those positions will be definitely shown in Fig. 7. In order to solve the defects according to the position The potential distribution of the potential compensation electrodes 40a, 40b should be small, and the width and thickness of the electrodes should be trimmed to reduce their resistance. However, when considering the fact that it is used as a display read device, When the touch screen is designed, it is impossible to extend the width and thickness of the electrode without limitation in order to reduce the resistance of the potential compensation electrode. &Amp; Mingren: Because of this, based on the spirit of active invention, I urgently want to It can be solved, the above problem "the structure of the touch screen electrode and the flat display containing the above structure" after several research experiments until the completion of this novel progress [summary of the present invention] i the present invention allows a potential compensation Distortion between the electrode and the transparent electrode 'by adjusting a paper size between the potential compensation electrode and the transparent electrode Standard (CNS) A4 size ⑵G X 29 external copy -------- ^ --------- (Please read the note on the back?

Description of Invention (ί)) Insulator areas were compensated, and their names could change. Therefore, the contact resistance between the daggers is another object of the present invention. When the touch screen is attached to a narrow area without potential distortion, it reduces the area between the potential compensation electrode and the transparent electrical insulator. Especially when there is a distance between the #insulator and the signal application contact. The purpose of the present invention is to provide a flat display with a touch screen, and signal distortion can be maintained by maintaining the touch screen. In order to accomplish these objectives, according to an aspect of the present invention, the electrode structure used in the electric touch screen includes an X-axis potential compensation electrode in the X-axis direction, It is made of low-resistance metal and arranged on both sides of a transparent conductive film.

The lower base and the upper base are on each other This indicates that the private electrode contains insulators 〇 04 a and 104 b, which are formed along one long axis direction of the two edges of the transparent electrode 102, so that a contact resistance regarding the signal application part can be determined according to the position. Change, when it is far away from the signal application part, it is achieved by reducing the area of the electrode. The potential compensation electrodes 101a, 101b are formed in a region on a thin film, and the insulator is formed on the transparent electrode relative to this region. This insulator It insulates those potential-compensating private electrodes and transparent electrodes from each other. The potential-compensating electrodes 1 0 1 a, 1 〇 丨 b are formed of a low-resistance metal, and are along and on the insulators 104a, 1 on the transparent electrode. 〇 In the servo area, with respect to the contact surface of the insulator, 1 05b is composed of a variable contact resistance layer. When the insulators 104a, 104b and the potential compensation electrodes 10 & 101b are in contact, Location. V. Description of the invention ((3) Those insulators with different densities are formed on the transparent electrode 102, and those with electricity = compensation == two or two series and are placed there. Those insulators are purchased, 1 〇Pak is formed: The irregularity of the degree is caused by the fact that the insulator μ of the signal application part ι03 is raised and the density on the opposite side is reduced. $ 第 9 图 **, the density is adjusted The degree 2A [EA / m2] at the signal application portion ⑻ is greater than the density B [EA / m] at a distance from the signal application portion ⑻, so that the potential compensation electrodes 10u, 1 (^, and the transparent electrode 102) The contact resistance between them can change depending on the position. When those potential compensation electrodes 101a, 10lb are arranged on those insulators 104a, 1G4b, the density of insulators 1 () 4 & Insulators are advantageous. Figure 9 shows an example of the density adjustment by using dots. In addition, a continuous model can also be used for the same method of density adjustment. As shown in Figure 10, another electrode according to the present invention Containing insulators 104a, 104b, this insulation system is constructed to There is an internal boundary line, so that a contact resistance of the signal application part can be changed according to the position. By making the area of the insulator smaller when away from the signal application part, a potential compensation electrode 10a is formed in a region on a thin film. 10lb, and the insulator is formed on the transparent electrode 102 in this area. This insulator is used to insulate those potential compensation electrodes and the transparent electrode from each other. The potential compensation electrodes 101 and 101b are made of low resistance metal. Formed on one side is defined by a boundary line 106 and is adjacent to the internal boundary line 105. On the other side, a boundary line 107 is parallel to the transparent electrode 102, the insulators 10 乜, 104b, and the potential compensation electrodes 1 0 1 a, 1 0 1 b are in contact with each other on the contact surface 1 0 8 of the boundary lines 1 0 5 and 1 0 6, 519613 __B7 V. Description of the invention (丨 present) Insulators 104a, 10 and potential compensation electrodes 10a, 10b The variable contact resistance 所有 of all the regions within can be changed depending on the position. Here, those insulators 104a, 104b are formed to have a uniform density A [EA / m2] and are distributed flat, but those insulators are formed The shape of the layer is configured to have a relatively large area in the direction of the signal application section 03 and a relatively small area in the opposite direction. In this way, the widths of the insulators 10 ″ and 104b are adjusted. As a result, the width is interfaced It is determined by the shape of 105. < The interface 104 of the insulators 104a and 104b ordered on the transparent electrode 102 may be a curve as shown in FIG. 10 or as shown in FIG. In a straight line, the insulator area becomes larger as it approaches the signal application section 〇 03 and becomes less § L source away ## application section 〇 03. The contact between those potential compensation electrodes 10la and 10lb and those of the insulators 104a and 104b also has a curved and straight line interface 10b relative to the interfaces of the insulators 104a and 10b 105.01 employee consumption Fig. 10 shows an arrangement of electrodes, including flat-shaped point insulators 104a, 104b and a curved interface 105 whose width is changed from the signal application portion 103, and the potential compensation electrodes 10la, 10lb The interface ι〇6 is in contact with those insulators 104a, 104b.

Invention Description ((ί) As they moved further from the signal application section 03, the trade-offs were not given according to those positions, that is, here In the structure, the widths of the insulators 104a and 104b change linearly. In addition, Figs. 12 and 13 show those insulators 104a, 104b which have a continuous pattern instead of dots. When those positions are defined by the model at the signal application section 103, the interface 105 has a relatively large width, while those located far away from the signal application section 103 at the interface defined by the model 10 have a relatively small width. Figure 12 shows a situation When they change further from the signal application section 〇〇3, the trade-offs are given according to those positions. Figure 3 is a situation, and when they change from the signal application section 103 to further, the trade-off 値Not given according to those positions, that is, in this structure, the width of the insulators 〇〇4 a, 丨 〇4 b linearly changes along the interface 105. According to the electrode structure of the touch screen, when it is Application as shown in Figure 4 When the touch screen is attached to a flat display, a potential compensation electrode area a2 is included in an edge area a of the LCD. In the case of a flat display with a touch screen attached to it, a polarizer 112 It is placed under a touch screen with an upper substrate 110 and a lower substrate U1.

The potential compensation electrode area a2 of the touch screen contains insulators 10 and 4b, so that a contact resistance of the signal application part can be changed according to the position. By making the area of the electrode smaller when away from the signal application part, a potential-compensating electrode is formed in the area on the thin film, and the insulator is formed on the transparent solar electrode 103 in this area j. This insulator makes those Potential compensation private wood 〇1 a 1 0 1 b and transparent electrode are insulated from each other, made of low resistance metal ------------ • install ------ (Please read the note on the back first Please fill in this page for the matters) China National Standard (CNS) A4 specification (210 297 um) M9613 A7 printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs and printed with the invention description (丨 b) of the potential compensation electrode And on the transparent electrodes insulators 104a, 104b and that: the variable contact resistance layer 115 'which contacts one #M, P two potential compensation electrodes 101a, 101b each other, all areas, the contact resistance can be in accordance with The difference in position and the shape of the insulator of the resistance layer 115 may be a continuous model as shown in FIG. 10 and FIG. Ii. The U-shape or electrode structure of this arrangement as shown in Figure 12 and Figure 13 is similar to the distortion of the potential of the wiper in the procedure of measuring position information. When a signal is applied to the touch screen, the potential in the touch screen is generated in the form of a sense of ^ and a substantial potential. In order to obtain accurate position information, 'the potential should be formed perpendicular to the signal application direction as the ideal potential'. However, when the potential is measured on the touch screen, the ideal and solid potentials are generated simultaneously. In addition, the larger the distance from the signal application part, the greater the error between them (refer to the potential distribution in Figure 7). This kind of phenomenon is mainly caused because the resistance between the potential compensation electrode and the transparent electrode is not large. When & it cannot be generated by other factors. In order to solve this problem, the resistance of the potential compensation electrode should still be relatively small. Therefore, adjusting the width and thickness in the direction where the resistance becomes reduced may be another option for generating resistance. However, when designing a touch screen, it is practically impossible to increase the width and thickness without limitation to reduce the resistance of the potential compensation electrode. This creates very important service goals for designing touch screens as input devices, such as thin, light, and slim, with opposite results. Because of this phenomenon, in order to obtain the LCD panel, when the touch screen is used in this paper, the Chinese National Standard (CNS) A4 specification (210 X 297 29%) is used. -------- ^ ---- ----- (Please read the notes on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 519613 V. Invention Description ((1) When added or integrated into the LCD, the potential is processed Compensating the resistance of the electrodes is more difficult. In the current situation where the touch screen is attached to the LCD like an input device, such as a thin touch screen whose size exceeds the edge of the LCD. The above fact is due to the 'design can be It is impossible to apply a touch screen electrode such as an LCD with a narrow edge area. As a result, the electrode width is reduced in order to appropriately stack a touch screen such as a thin film over the edge of the LCD, thereby increasing the resistance, so linear Errors were generated, and the last touch screen was generated. Therefore, the electrode design of the touch screen without linear errors and the edge of the LCD is completely limited, and its influence is directly related to the location information. The electrode design factors of the touch screen according to the present invention are summarized as follows: First, when the touch screen is added to the display device as an input device, the width requirements applicable to the touch screen are reduced. Trend (like LCD, the edges of CDs are decreasing). Secondly, there is a tendency to decrease and decrease as it applies to touch & screen width requirements, the possibility of inferior touch screens will be generated due to touch Screen electrodes tend to increase linearly. Third, in theory, contact resistance should not be generated between the transparent electrode and the potential compensation electrode. However, contact resistance actually exists in the meantime, and it has an effect on the potential distribution. In order to accurately detect the position, the potential Δ ′ potential should be formed perpendicular to the signal application direction as the ideal potential. However, when the potential is actually measured on the touch screen, it forms a curved shape, but Not like the ideal potential curve. Finally, when it is in accordance with the Chinese national standard (CNSW specification (21〇X 297 tolerance)) with this paper scale ---- ----- Order --------- (Please read the precautions on the back before filling out this page) 519613 A7 _B7 V. Description of the invention (when the application part of I?

Insulator 1104 "is formed on the transparent electrode 3 in this region, and the insulator is used for those The potential compensating electrode and the transparent rain electrode are insulated from each other. This insulator makes the signal application part: the contact resistance can be changed according to the position, which makes the electrode area smaller when it is far away from the signal application part. Therefore, the contact resistance is The part ι〇3 becomes relatively large and away from the signal applying part in order to compensate the potential as shown in FIG. 7; the V bit is distorted, at the transparent electrode 102 and those potential compensation electrodes 10a, 10b. The contact resistances between 10U and 101b need to be adjusted. This adjustment of the contact resistance is equivalent to the area between the transparent electrode 102 and those potential compensation electrodes ιom and mb. Therefore, the potentials ⑴ ... shown in FIG. 6 can be adjusted to the ideal potential splits as shown in FIG. As a result, the linearity error of the electrodes can be removed. In order to adjust the area of the insulators 104a and 104b, and form the methods of those insulators 104a and 104b, they are mainly classified into dots and model shapes. It is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, which is used when away from the signal application part. The area above becomes smaller. As shown in Figure 9, the method of adjusting those insulators, the insulator density is changed according to the distance from the signal application part, the method shown in Figures 10 and η, potential compensation electrodes 101a, 10lb The interface ι〇6 is configured to be in contact with the curved or straight interface 105, so that the widths of the insulators 〇04a, 104b become narrower away from the signal application portion, and in FIGS. 12 and 13 The method shown, potential compensation electrode 丨 〇 丨 a. This paper size is applicable to China National Standard (CNS) A4 specification (210 X 2972 centimeters) 519613 ------— B7 ___ V. Description of the invention (I)) (Please read the precautions on the back before filling this page) The interface 106 of 101b is configured to contact the curved or straight interface 105, so that the width of the insulators 104a and 104b is formed by a continuous model rather than a point and is The signal application portion becomes larger and the distance from the signal application portion becomes smaller, and the aforementioned method can be optionally applied. As a result, the freedom of design will increase. All the electrode structures shown in Fig. 8 and Fig. 13 are configured so that the potential distortion generated during the detection position information procedure as shown in the graph of Fig. 7 cannot be compensated. Fig. 14 shows a structural example of a touch screen according to the present invention applied to an LCD as an input device. A sheet-like stacked touch screen includes an upper substrate 110 and a lower substrate 11i. A polarizer 112 is attached under the touch screen, a liquid crystal element 113 is attached under the polarizer 112, and another polarizer 114 is in a liquid crystal. Below the display device 113, all of them are sheet-like and stacked together, and the compensation electrode area a2 of the touch screen can be arranged on the edge a1 of the LCD. In the conventional case, when the potential distortion is reduced by reducing the resistance of the potential compensation electrode, the area of the compensation electrode has exceeded the edge of the LCd. However, the electrode design according to the present invention maintains a large potential compensation. Bureau staff eliminates the need for printed pole widths and thicknesses of cooperatives. Therefore, the compensation electrode area can be fully applied to the edge of the LCD. As described above, the present invention has the following advantages. The potential distortion can be compensated by adjusting the area of the insulator between the potential compensation electrode and the transparent electrode of the resistive touch screen and changing the contact resistance therebetween. _ 步 地 'Another # advantages, the touch screen can be applied to narrow areas without potential distortion distribution, which is the ratio of the insulator area between the potential compensation electrode and the transparent electrode when the insulator is away from the signal application part This paper size applies to Chinese National Standard (CNS) A4 ^ i7iI ^ x 297¾¾) 519613 A7 V. Description of the invention (, small. This: 'advanced-advanced' advantage, with a two-sided display attached to the touch screen, which The signal distortion is compensated by maintaining the linearity of the potential compensation electrode attached to the touch screen of the flat display. In summary, the present invention is different from the conventional technology in terms of its features, methods, and effects.
