New Description: 【New Technology Fields】 This is a kind of improvement on the structure of a duplex touch panel, especially a touch sensing interface with capacitive touch panel and resistive touch panel. A device for controlling reception processing of an induced signal. [Prior Art] The touch sensing device used in the display screen surface of electronic products has become more and more mature in recent years. The performance and quality of related component products have been continuously improved, and the price has been greatly reduced. Therefore, various touch sensing devices have been widely used in various electronic products; in general, touch sensing devices can be slightly divided into capacitive touch panels, resistive touch panels, and electromagnetic touch panels. There are three major types, and each of these touchpads has its own features, advantages and disadvantages. Therefore, the current application layer is different. For example, resistive touch panels are often deployed in personal digital assistants (PDAs) and electronics. It is used on the screen of small electronic products such as dictionaries, mobile phones, digital players or satellite navigation screens (GPS), while capacitive φ touchpads are mostly used as mouse pads for notebook computers, virtual touch buttons, and so on. The structure of the resistive touch panel mainly comprises two planar transparent conductive films arranged in a split-fixed gap, and the upper conductive film is disposed on the surface of a flexible transparent film and is electrically conductive underneath. The film is disposed on a surface of a transparent glass substrate having a hard material, and the two conductive films are sealed in the plate body; the upper and lower conductive films and the plate body of the resistive touch panel are transparent materials, It is suitable for being placed in front of the display screen of electronic products. It allows the user to tap the desired position on the screen to tap the desired position of the panel, and the input function can be used, and the pen tip and the like which are generally available can be used. The M335736 has been accurately operated by the ship, so it can be used for the input of the small (four) face and the precision of the pen, especially for the input operation of the secret pen Newton or the face lion; however, the aforementioned resistive touchpad By the input operation mode of the touch panel, the guide inside the board can withstand the anti-river force and the guide, so the life is limited, and when the hand is used to reduce the large workmanship, Miscellaneous Input accurate results, thus also using the input tool many restrictions. The capacitive touch panel structure includes a χ-axis sensing layer (X _) and a y Φ-axis sensing layer (y trace), so that the X-axis sensing layer is insulatedly disposed within the touch panel body, and The X and y-axis sensing layers are respectively grounded and connected to a control circuit. When the finger or the conductor touches the thief to reduce the _ control wire φ, the hand is reduced by the hand of the thinner to generate a capacitive effect. Therefore, the control circuit can determine the touch position of the finger or the conductor by the change of the capacitance value; since the capacitive touch panel can be input by the finger, the convenience of the input operation is required, and the input and the manipulation need to be The panel has the disadvantages of being subjected to repeated stress and deformation, and the touch panel has a simple structure and few components, high yield of Lu products, and is suitable for mass production to reduce costs; in addition, the touch panel has many The performance of point sensing, which means that the touch sensing device has the performance of multiplex control, so it can be used in high-order control operations, for example, in the manipulation of video games, so that the virtual subject being manipulated can be more move More flexible or more diverse performance performance; However, the capacitive touch panel can be easily input using a finger, but the accuracy of the finger input method is not high, and it is easy to cause misoperation, causing troubles in use. Especially for the input of text recognition, such as Chinese characters, such as strokes with more strokes or complex shapes, the recognition rate is extremely low, and it is still difficult to achieve a practical degree, although the former M335736 is soft, the year and the moon are '丄匕j »..^V · -I; -i. ; The problem can be overcome by using a special induction pen, but it is still used for point input on the board or for higher precision. Restriction, and the use of a dedicated sensor pen, often makes the user feel very inconvenient in many occasions, such as when not carrying or losing the pen. In addition, in recent years, some capacitive touch panels have been modified to use a light-transmissive insulating material as a substrate, and a low-impedance transparent conductive material such as silver paste is used as a sensing layer to form a transparent capacitive touch. The control board is therefore suitable for the display of the electronic product, so that the user can input the function by tapping the indication on the screen to lightly touch the desired position of the panel; this conventional transparency Capacitive touch panel, the silver-glued conductive material of the sensing layer is not completely transparent, and the sensing layers are respectively formed by diamond-shaped lattice 峨(10)W_j; (Tfaee), so that the light transmittance of the working area of the fine chick is not formed. _The trace portion and the trace portion (ie, the touch portion), due to the different light transmittance of the stitch portion and the non-track portion area on the flip-flop capacitive touch panel, still cause X-ray touch At the bottom of the control panel, the image of the screen is refracted unevenly, which causes the distortion of the image. ,································································································· It is what you are. [New content] ...; This creation is mainly to provide a kind of dual-power control board structure improvement, which integrates the electric touch panel and 1: (4) into her-board system, and has the performance of the secret two-sided control board. And the advantages, and the / / board has a uniform light transmittance, which can improve the display blur distortion of the display screen at the bottom of the touch panel.

Any modifications or changes to this creation should still be included in the protection of this creative intent and shall be stated. The following description will continue with a specific embodiment to further clarify the innovative features of the present creation. [Embodiment] As shown in the first to second embodiments, a preferred embodiment of the present invention includes a capacitive touch panel unit 1, a resistive touch panel unit 2, and a signal processing unit 3; The capacitive touch panel unit 1 includes a surface layer U, an x-axis sensing layer 12, a γ-axis sensing layer 13, an insulating layer 14, a substrate layer 15, and a first signal output cable 16; wherein the surface layer 11 And the base layer 15 is a high transmittance insulating thin layer material, which is selected from the group consisting of glass, polycarbonate (PC), polyester (Pythylene terephthalate, PET), and polymethylmethacrylate (polymethylmethacrylate).

Further, as shown in the first and second figures, the x-axis sensing layer includes a plurality of transparent stitches 121 arranged equidistantly and arranged in parallel with each other, and the γ-axis sensing layer 13 s has a plurality of transparent stitches arranged equidistantly and arranged in parallel with each other. (3) The width of the stitches is usually about _~5 mm, and the interval between the X-alkaline and the γ-decreasing layer 14 is such that the X-axis stitches 121#Y axial stitches 131 are perpendicular to each other. Crossed and arranged opposite to each other; further, at the line end of the χ axial stitch 121, there is a stitch contact 122, and at a line end of the γ axial stitch 131, there is a stitch contact 132, and the stitches are connected Points Φ I22 and m can be respectively electrically connected to the silver guiding paths 101a, 101b disposed at the edge of the panel, and connected to the first signal output wiring 16 to thereby induce the X-axis sensing layer 12 and the Y-axis sensing layer 13 The signal can be transmitted to the subsequent signal processing unit 3 via the first signal output cable 16. As with the above arrangement, an equivalent capacitance is formed between the x-axis sensing layer 12 and the silver guiding path 161a, and there is also an equivalent electric valley between the γ-axis sensing layer 13 and the silver guiding path 161b.

Insulating glued layers and glued to each other to form a transparent conductive film. The material of the thief is placed on the edge of the panel. The set is sent to the second signal to transmit iU Lin 26, and the new transmission service number processing unit 3; As described in the foregoing structure, since the thickness of the capacitive refresher element is very thin, mounting on the resistive touch element 2 reduces the sensitivity of the touch-sensitive sensing of the resistive touch panel unit 2, However, the stress impact of the indium tin oxide film material of the upper conductive film 22 can be alleviated, and the damage of the sharp edge strain can be avoided, so as to prolong the use of the #可_娜娜杂衫2 New Zealand thief electric material touch fresh f ^= square 'This setting also allows the creation of the function of both resistance and capacitance. The signal processing unit 3 can automatically select an appropriate signal processing mode by using the touch sensing signal type transmitted by the capacitive touch panel unit i and/or the resistive touch panel unit 2 According to this, the signal processing step is performed; for example, when the user performs an input operation on the composite touch panel of the present by a finger, the touch of the finger is on the X-axis sensing layer 12 and the γ-axis of the capacitive touch panel unit 1. The sensing layer 13 creates a capacitive sensing signal that the finger does not apply a compressive stress to the surface of the board, so the resistive touch panel unit 2 does not generate any signal; as a result, when the capacitive touch panel unit i When the capacitive sensing signal is transmitted to the signal processing unit 3 through the first signal output cable 16, the signal processing circuit of the signal processing unit 3 is automatically determined according to this and is selected to operate in the capacitive sensing signal processing mode. The attendant unit 3 accepts and processes the inductive signal of the electric valley type touch panel unit 3 and blocks the inductive signal of the resistive touch panel unit 2; for example, when the user uses the nib to collide the original composition When the touchpad performs an input operation, the nib touches the working area of the surface layer U due to the capacitive touch on the top 12
