New Description: [New Technology Field] This creation is about a touch panel', especially for a touch panel with an induced hole structure. [Prior Art] At present, the mainstream touch panels on the market are both resistive and capacitive. Among them, the resistive type has four-wire resistance type, five-wire resistance type, six-line, seven-line or nine-line resistance type, and the capacitance type is divided into Surface Capacitance Touch Screen (SCT) and projected capacitance type (Projective Capacitance). TouCh Screen, PCT). Among them, the projected capacitive touch panel is also called touch touch technology, and the resistive and surface capacitive panels can be called analog touch technology. Projected capacitive touch panel _ technology, which is also divided into self-contained and mutual-capacitance ^ Among them, self-capacitive touch technology uses the concept of scanning lines to carry out the χ axis and 丫 sweeping 瞎, and then by X-axis sensing The multi-touch measurement can be performed by calculating the amount and the Y-axis inductance. The mutual-capacitive touch technology uses one axis as the driving line (for example, another axis is used as a sensing line (for example, by driving the line sequentially to drive the 'sensing line for overall sensing or sequential sensing), and the point can be obtained. The inductive signal' can be used to make multiple touches. _ The ability to tear a lot of points is difficult to control by the frost capacitors, and the _ _ _ _ _ _ _ _ _ _ _ _ _ _ The design of the residual sensor of the butterfly control panel must allow each touched finger to touch the multiple scans. It is a conventional projected capacitive touch panel. The two-layer structure of the Y-axis electrode lion is staggered. On the contact side, it simultaneously touches the M429138 axis scan line X1, X2, X3, X4, Χ1ι χ2, X3 scan line, 丫 axis scan line Yir7^2rY^Y4 All. Because of the dense scanning line on the touch measurement, the more accurate touch detection judgment can be achieved. Therefore, this design concept has been the standard for projecting capacitive touch panels. Multiple scans _ design, easy on small-sized panels OK, however, on a large-sized panel, 'there will be too many scan lines. So, on a large-sized projected capacitive touch panel, the scanning circuit (or control circuit) must bear a large number of control lines. The solution to the problem is to use a control chip for multiple scanning circuits. In addition, the conventional projection capacitance extraction surface (4) touch system must be changed from the side to the electric valley of multiple scanning lines. Moldy ground judges the touch action. This also becomes a big burden on the back touch touch meter. Therefore, if you can reduce the number of scan lines, or if you can improve the touch amount of the finger touch, you can The accuracy of the measurement of the electric valley type touch panel has another application, that is, the projected capacitive touch panel is simultaneously used as an electromagnetic touch panel, that is, by color The projection capacitor and electromagnetic touch panel solution provided by the bribe. There are two types of touch panels that can be used in this projection capacitor and electromagnetic touch panel solution. The first one is the existing one. Capacitive touch panel, as shown in Figure 1 or 'X-axis, 丫-axis vertical staggered electrode sensor structure. The second type please refer to Figure 2A and Figure 2B. In the figure to solve the projected capacitive touch panel The high-impedance problem can reduce the width D1 of the electrode by reducing the gap between the X-axis inductive 〇 of the projected 〆I panel and the gap IQ of the Y-axis driving electrode 12〇. This can reduce the impedance of the touch panel. And further preferably M429138, in addition to the double-layer 丨 〇 structure of Fig. 3A, it is also possible to use R|m/丨丁〇R"m two-position, or adopt the structure of ITOCoverLens/rrOFilm, that is, A structure in which two conductive layers can be provided is used. In the 3A drawing, on the X-axis scanning line 11A as the sensing line, the hole area 140 is disposed at the position of each node. The hole region 14G is designed with a complex hole (penetrating electrode layer) for the purpose of causing an electric field formed by the γ-axis scan line 12〇 as a drive line to penetrate the X-axis scan line 110 via the induction hole, so that In the capacitive sensing mode, better sensitivity can be obtained. ® In addition to the design of the scan line structure, the width D1 of the X-axis scan line 110 is larger than that of the scan line. The width D2 of the gap 彳2 is wide, so that the impedance of the X-ray trace can be lowered. Please refer to FIG. 3B, which is a schematic diagram of an electric field formed by the touch panel with the induced hole structure of FIG. 3A. Comparing Fig. 2B, it can be seen that due to the design of the induction hole 141, the electric field 200 emitted by the paraxial scanning line 120 can partially penetrate through the induction hole 141 to the x-axis. Thus, the electric field strength of the touch-sensitive interference increases, which in turn increases the sensitivity of the capacitive touch sensing. This design can be used alone in the application of the capacitive touch panel, especially for electric grid pens. A capacitive touch panel for both fingers. Since the area of the pen of the capacitive pen is much smaller than that of the finger, the amount of capacitance that can be generated by the capacitive pen will be much lower than that of the finger, which also makes the '_ of the capacitive pen less difficult. At this point, the sensitivity of the capacitive touch detection can be increased by the induced hole structure of the present invention, thereby providing a better sensitivity of the capacitive pen. Please refer to the 3C figure. When the capacitive pen 3 is applied to the touch panel with the induced hole structure of the present invention, 'because the writing head of the capacitive pen 3 is small', the electric field interference generated by the scanning line for the x-axis may be generated. small. However, due to the presence of the induced aperture 141 of the present creation, the electric field of the capacitive pen 3 capacitance = T line 110 forms an interference, x. The production of the finer and the movement of the capacitive pen 3 is easily detected. The electronic creation panel structure can also be used for capacitive touch detection, especially for the electric pen and finger dual-use touch panel. Referring to Fig. 4, it is a schematic circle of the first example of the touch panel with the induced hole structure. In Figure 4, the rust is configured. The third and fourth figures of the gamma (4) W car hole are used to illustrate the induced hole structure of the induced hole.

Among them, the induced hole of the third figure is a slender rectangle, and the long side of the virtual X-turned _彳 side and the X-coded t-shirt can be. And the 4th _ guide hole _ a small rectangle is drawn in parallel _ way. Along the X-axis, the 11G long side is equipped with a fine gauge, which improves the X-axis sweep 0 (4) ugly. New: If the impedance improvement problem is not considered, the induced hole can also be designed such that its long side is orthogonal to the long side of the x-axis scan line 110. The design of the induced hole region of the FIG. 3 and FIG. 4 is mainly used to increase the electric field emitted by the driving line to increase the electric field that penetrates the sensing line and reaches the touchable area. Therefore, there is no specific limitation on the shape, for example, the third figure or the fourth shape, or a square shape, a circular shape, or the like, and the size of the induced hole can be dynamically adjusted according to the width of the scanning line. In addition, the induced hole area can also be designed on the drive line. Please refer to FIG. 5, which is a third example of the touch panel 1〇3 of the creation of the induced hole structure. The width 诱导 of the induced hole in the 15th inducing hole region of the fifth figure is the same as the gap width 〇2 of the gap 112 of the scanning line. Further, the gap 112 of the scanning line 11 is arranged equidistantly from the induction hole M429138 (evenly arranged). Because the gap 112 of the scan line 110 is the same as the induced hole, the electric field emitted by the lower layer of the driving line can be passed through. If the two can be evenly arranged, the sensing of the sensing line in practice will be uniform. effect. That is, the uniformity of the amount of inductance when the capacitive pen or the electromagnetic pen or the finger passes through different regions can be improved. In this way, the touch detection accuracy of the present creation can be improved. In the application of the electromagnetic touch panel, since the electromagnetic touch panel adopts the electromagnetic induction method of the circuit, there is a problem of poor sensing at the edge portion. For this question, please refer to the implementation of the 6th _ solution, which is the difficult touch panel of the touch panel 1〇4 • The fourth example is schematic. When the touch panel structure having the induced hole structure is used in the present invention, at least one edge electrode may be added to each of the driving line and the sensing line edge of the touch panel. As shown in Fig. 6, it is an embodiment in which two edge electrodes (χρΐ, Χρ2, Χρ3, χρ4) are added to the edges of the sensing line. Since the manner of increasing the edge electrodes of the driving lines is the same as the manner of increasing the feeling wires, it will not be described. The increase of the edge electrode is intended to allow the sensing lines of the edge such as Χ1, χ2, χ7, χ8, etc. to be used as the electromagnetic induction circuit, thereby making the positional side of the edge more accurate. As for the edge electric (4) production method, the production method of the Cheng Ying line can be the same, for example, _ Μ using transparent electrodes to make. Alternatively, it may be different from the method of manufacturing the sensing wire. For example, the process of using the silver paste process minimizes the edge and further meets the requirements of the financial side. In addition, the edge resistance of the edge electrode can be used to obtain the impedance of the ship. ...
