New description: [New technical field] The author is related to the tunable round-off signal_control panel signal transmission structure, especially the kind of signal transmission path that can be used in the transmission process. Correct the signal 'ship _ secret department 妓 _ people should be destroyed, shoot Lin - meet the specific specifications of the output signal. [Prior Art] In recent years, the touch panel has become an important input device, which is widely used in display screens such as liquid crystal display 7FH or cathode ray tube, so that the manufacturer can pass through the display screen. It refers to the function of inputting signals without touching the desired position with a finger or a pen tip. The touch panel usually includes two surface-shaped conductive-on-time-fixed gaps, and the opposite arrangement, in which at least one conductive film is disposed on a flexible transparent film, and the other conductive film is disposed on A surface of a rigid substrate is provided with a plurality of flat strips for conducting and insulating between the opposite sides of the opposite arrangement, and a bonding area is applied to coat the adhesive layer, thereby sealingly bonding the two together. The conductive thin layer has a conductive layer deposited on the surface of the conductive material, such as indium tin oxide (JTO), and the signal on the conductive film is electrically connected to the silver guide on the side edge (Siiver_c) 〇ntainjng c〇n (juctive eiectr〇(je) is transmitted to the signal processing circuit', for example, as shown in the third figure, the signal triggered by the first portion 1>1 on the conductive film T is the shortest conduction distance A path D1 is transmitted to the silver guiding path R, and then the signal is transmitted from the first signal input point Κ1 of the silver guiding path to the line end of the silver guiding path to output 'same reason, the second part on the conductive film The signal triggered by ρ2 is transmitted from the second path D2 of the shortest distance of M335738 to the silver guiding path, and then the signal is transmitted from the second signal rounding point η to the line end of the silver guiding path, and is output; It can be seen that the signals triggered at different positions on the conductive film are transmitted to the subsequent signal processing circuit via different conduction paths. However, since the general silver guiding system is electrically connected by the elongated planar strips, The aforementioned guide The side edge of the ray, and the silver guide itself has a higher impedance (mipedance), and the impedance will cause the signal to decay during the signal transmission. Therefore, when the signal is different from the silver guide, When K2 is input to the line from the line end, the Lu signal will bear the _anti- (four) shadow _ with different degrees of attenuation, _ is the farthest part of the silver guide from the output line end ^ and the nearest part private The attenuation degree of the transmitted signal between the two is more obvious; this result, if the signal fading _ is severely different, it will affect the accurate positioning of the contact points on the touch panel, resulting in the operation of the subsequent signal processing circuit. Therefore, most of the current practice is to perform a calibration procedure that corrects the signal strength during the signal transmission process in order to obtain a signal that meets the specified specifications. Some have _ with complex conductive patterns - (c_ictivepattems) to redistribute the signal ' or additional string communication circuit in the guide to control the redistributed signal to reduce the signal during the transmission process In the case of attenuating the unevenness of the sentence, the method of providing a reinforcing electrode disclosed in, for example, the patents of the U.S. Patent Nos. 4,293,734 and 4,661, 655, as shown in the fourth and fifth figures, is utilized in the conductive film T. The edge of the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In order to reduce the attenuation value when the signal is transmitted to the M335738, the purpose of finding the difference between the two ends of the pole and the central part (four) is to eliminate the difference between the county values, and the design and calculation method of the helium electrode is not easy, and The production technology is more difficult, and it is easy to make errors in the manufacturing process, so that the two signals are not allowed to produce fresh results. Moreover, these complex conductive patterns are hidden in the power supply, and it is also difficult to make the panel. The mixture is smaller. In addition, in other signals, there is also a confluence path r__) which is provided with a non-parallel curved line at the edge of the conductive thin film, for example, In the six figures, the use of this curved equipotential field to add (four) scales to the brain is used to achieve the purpose of the signal; this conventional technique is simple to set up, but at the output of the confluence signal. It becomes a small size, which causes the current signal to be consumed in a large amount, which is its main disadvantage. Moreover, this is accompanied by the curved edge of the guide, which makes the appearance of the touch panel extremely abrupt and not very beautiful' and the read area of the touch panel. It is smaller. [New content] Recorded here, the main purpose of this creation is to provide a kind of signal transmission structure of the contact plate. The record is difficult to break the domain of each student in the transmission to the silver guide (electrode) Approximately the same attenuation value is obtained in the signal conduction path of the output end, so as to obtain the output signal value whose transmission signal voltage value is close to the same. — Root County _, Jane Control Surface _ 峨 财 乃 is the edge of the film. • There are multiple resistor units nearby, and each resistor unit has an appropriate spacing between each other to form a signal channel. The materials are arranged in a staggered arrangement with each other. The 'conductor-silver conduction path is electrically connected to the resistance unit and the conduction channel: the outer surface of the conductive f# film; by controlling the position of the resistance unit and the side of the M335738 The size of the signal transmission channel, which closes the impedance value of the signal conduction path of each different part of the conduction _ to improve the phenomenon that the signal is attenuated during transmission, so that the output terminal can obtain the same conduction signal voltage. The value of the output signal from each part. ° The above-mentioned resistor unit is made up of a thin electric circuit; the bell channel or hole system can be made by the method of surname. - New Zealand, the resistance units are elongated, and the length thereof is arranged from the inter-sheet portion to the two ends, and the side is arranged in a non-linear manner, or the width of the signal-conducting passages is made in the middle. The part is arranged in such a manner that the two ends are gradually reduced in a non-linear manner, or the mixture of the two methods described above is used in combination. This creation is not in the form described above. It is very familiar to the skilled person. 3 After reference to the above description, there can be more improvements and changes, so that all are made under the same creative spirit. Any modifications or changes to this creation should still be included in the scope of this creative intent and shall be stated. The following will be followed by a specific embodiment to further clarify the innovative features of the creation. [Embodiment] As shown in the following figures, the conductive film of the touch panel is disposed on the surface of a substrate 4, and the silver guiding path 6 is overlapped at the edge of the conductive film 1, so that the trigger is The signal on the conductive film can be transmitted to the subsequent signal processing circuit through the silver output path on the side and from the signal output end 61 of the two end edges; wherein the silver is close to the edge of the conductive film 1 and close to the electrical connection. A plurality of hollow channels 12 through the conductive film are disposed in the vicinity of the guide path 6, and each of the hollow channels 12 has an appropriate spacing width between each other to form a signal conducting channel 8 M335738 (channel) 13 The channels 12 and the signal conducting channels 13 are arranged alternately with each other; the conductive layer of the conductive film 1 is deposited by an indium tin oxide (ITO) material, so the hollow channels 12 are simply According to the side method, the side processing operation first coats (or prints) a layer of the corrosion-resistant coating on the surface of the conductive film, and then immerses the conductive film in a surname, such as hydrochloric acid or nitric acid. Solution, then removed by the side The unnecessary portion on the conductive film retains only the desired portion. As is known, the conductive film 1 and the silver guide 6 each have different impedance characteristics. The impedance value of the signal-conducting process towel is approximately the size of the cross-sectional area of the fiber-conducting channel. Proportional, and inversely proportional to the length of the conduction stroke; therefore, the above-described configuration of the present embodiment can be adjusted by controlling the length of the hollow channels 12 or the width of the signal conduction channels 13 during operation. The size of the non-impedance value of the 触发 触发 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 峨 各个 各个 各个 各个 各个 各个 各个 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电 导电The signal can be approximately the same when the transmission arrives at the signal output terminal 61. The conduction value is calculated and the operation processing of the continuous orbital noise circuit is performed. More specifically, as shown in the first figure, when the touch panel signal transmission and guidance structure provided by the present invention is arranged in such a manner that the length of the hollow channel I2 is arranged, the hollow channels 12 The length setting will be arranged from the middle part to the two end sides in a non-linear manner, so that there are shorter hollow channels 12 and dense signal conducting channels 13 in the middle part; as shown in the second figure The signal conducting structure is arranged by adjusting the width of the signal conducting channels 13 by arranging the widths of the signal conducting channels from the middle, and the P bits to a side edge to be non-linearly decreasing in width. Therefore, in the middle 呷9 M335738 has a wider domain channel 13 and two __(4) urban material channel i3 settings; according to this arrangement, the trigger signal in the middle portion of the conductive film i can be transmitted to the The smaller impedance value suffered in the path of the middle portion of the silver guide 6 and the larger impedance experienced by the trigger signal of the conductive film 1 at the side portion in the path transmitted to the edge portion of the silver guide 6 Value; although the silver guide The signal strength received by the road 6 in the middle section is higher than that in the fine duty (four) 峨, but the 峨 料 6 6 is sent to the 'signal output terminal 61 on the two sides'. Different 'size impedance values' produce different degrees of signal strength attenuation, that is, the signal output terminal 61 input from the middle portion has a longer conduction path and therefore will withstand greater impedance and The result is a large amount of intensity attenuation, which results in the same signal strength being obtained when the respective trigger signals of the conductive film 1 are transmitted to the signal output terminals & In summary, it can be seen that the pick-up channel and the signal conducting channel U are arranged in a staggered arrangement with each other to provide a correction to the different electrical connections of the silver guide. The intensity signal is used to correct the different impedance values of the silver guide at each input position. It is easy to say that the signal triggered from the position of each part of the touch panel transmits the renewal of the new number through the front signal transmission structure. The signal conduction paths of each Ke have the same or similar impedance values, and even if the signals have the same degree of attenuation, they can all be obtained - the output signals conforming to specific specifications, Daxun [schematic description] Partial plan view of the creation, showing the bell channel (4) layout side M335738 The second picture is a partial plan view of the other embodiment of the creation, the channel 13 is arranged; the display of the signal is transmitted to the third picture is a conventional touch The plan view of the panel panel is displayed on the conductive thin signal via the (10) conduction path; the fourth diagram of the 辄 is another plan view of the conductive film of the conventional touch panel, which is displayed on the edge of the film.
