New description: [New technical field] This creation belongs to the technical field of a touch panel. Specifically, it refers to a gradient phenomenon caused by different contact impedances at the same level or vertical, and can prevent current from reaching each other. The surface capacitive touch panel of the pin enables the touch panel to have a multi-contact determination function. [Prior Art] According to the appearance of the input interface of keyboard, mouse and touchpad in the history of electronic equipment, the problem of input control was solved. However, the space occupied by these input interfaces is not small. For example, half of the volume of a notebook or mobile phone is occupied by the keyboard. If you can save keyboard space, you can naturally improve the portability of the product. The most feasible way is to operate the touch panel directly on the panel. The touch panel can really replace most of the keyboard and mouse functions, and give users a more intuitive and convenient operation experience; replace the keyboard with a larger panel, and design a thinner and more stylish style; plus fully solid state Panel technology, no need to worry about the failure of mechanical parts such as keyboards, pulleys, etc. From the technical principle to distinguish the touch panel, it can be divided into resistance technology touch f board, capacitor shaft (four) panel, infrared technology job board, surface acoustic wave, _ control tons, electric noise control board and * learning technology touch, Board and so on. Among them, the positioning of the (10) type touch panel is accurate, but its price is easy to use? : Infrared technology touch panel is low in price, * makes it easy to produce light interference, and distortion in the case of the surface; however, the main isolator panel solves various defects of the previous touch screen, clear and anti-riot, suitable for secondary ^ β ^, valley In this case, the water droplets on the surface of the panel and the dust 3 M403700 soil will make the touch panel dull or even not working. Therefore, current touch panel development has become the main product on the market, considering the combination of resistance, cost, response speed and convenience. In recent years, the smart touch screen of smart phones has given smartphones the opportunity to win more people's favor. The emergence of multi-touch functions [such as iPhones, HTCs and other smart phones] has led to a new revolution in the use of interfaces, and Shuneng Qian's intuitive use of electronic products that require multi-touch panels. However, in the past, the multi-touch smart phone has been launched for some time, but it has not seen the emergence of similar concept products in the market. It is obvious that there is a high threshold in the practice of technology. Currently, there are many touch technologies on the market, and only capacitive technology is expected to realize multi-touch functions. Looking further, capacitive touch can be divided into surface capacitive type [Surface Capacitive] and projected capacitive type [Projective Capacitive]. In terms of surface capacitive technology, as shown in the first figure, A conventional surface capacitive touch panel. The touch panel (1) is composed of a transparent substrate (11), a transparent conductive layer (12), an electrode pattern layer (13) and a hardened layer (14) for insulating protection, wherein the transparent substrate (11) may be glass or plastic, and the electrode pattern layer (13) is formed on the transparent conductive layer (12) by forming two opposite X-side electrodes (131) and two opposite Y-side electrodes (132) formed in a rectangular shape. The peripheral portion is used to compensate for the curve distribution of an electric field on the transparent conductive layer (12). In addition, as shown in the second figure, the four corners of the touch panel (1 〇) are connected to an external wire (151, 152, 153, 154) 4 M403700 for receiving an alternating current sensing signal respectively. [AC1, AC2, AC3, AC4] 'Used to measure the position of a contact p on the touch panel. In actual operation, the AC sensing signals ACl, AC2, AC3, and AC4 are AC square wave or sine wave voltage signals of the same amplitude. At this time, each of the external wires (151, 152, 153, 154) has one Currents 12, 12, 13, and 14 pass. By measuring the amount of current change ΔΙ1, ΔΙ2, ΔΙ3, and ΔΙ4 of each of the outer leads (151, 152, 153, 154) before and during the occurrence of the contact P, the X and Y coordinates of the position of the contact P It can be calculated as follows: Χ=(Δ Ι3+Δ Ι4-Δ Il-Δ 12)/( Δ Il + Δ Ι2+Δ 13+Δ 14) Υ=(Δ Il + Δ Ι4-Δ Ι3- Δ 12) / (Δ Il + Δ Ι 2+ Δ Ι 3 + Δ 14) Therefore, in the operational architecture, the system will generate a uniform electric field in the transparent conductive layer (12), when the finger touches the panel, the capacitive charging effect will occur, and the upper electrode of the panel The transparent X and γ side electrodes (131, 132) of the pattern layer (13) form a capacitive coupling with the finger, thereby generating a capacitance change, and the controller can measure the four corner current intensities according to the current size. . Since the electrostatic field is changed by touching the touch panel with a finger, the single-touch capacitive technology is quite mature, and is also a Surface Capacitive. This technology architecture is relatively simple, only a transparent conductive layer (12) can be realized, and this transparent conductive | (12) + requires special sensing channel design, only need to connect 4 wires (151, 152, 153, 154) ) and the grounding wire can be used, and the production difficulty and cost can be reduced. The biggest limitation is that it benefits multi-touch reduction, mainly because it is in the actual Guardian #: At the same time, 5 M403700 is applied to more than two contacts, and the gesture between the two contacts is performed. When [such as zooming, rotating or dragging], it may cause the output currents to cancel each other due to the corresponding position of the two fingers, causing misjudgment of their contacts or actions. Therefore, the existing surface capacitive touch panel is not multi-point. The ideal technology for touch. So. Projected Capacitive technology is the hope of multi-touch. The third figure is an exploded perspective view of a conventional projected capacitive touch panel. The capacitive touch panel (20) is composed of a transparent substrate (21), an X transparent electrode pattern layer (22), a transparent dielectric layer (23) and a Y transparent electrode pattern layer (24) from bottom to top. Forming a stack, wherein the X and γ transparent electrode pattern layers (22, 24) each form a row/column sensing pattern (25) [sensing element] for use in conjunction with other components to determine the touch panel ( 20) The presence of one or more contacts, wherein the sensing patterns (25) of the X and γ transparent electrode pattern layers (22, 24) are in contact with a plurality of external leads (28). Compared to the surface capacitance type, the projected capacitive single layer or multi-layer patterning forms a row/column interleaved sensing pattern (25) [sensor element] matrix. In this way, the precise touch position can be obtained without calibration through the entire life cycle, and a thicker overlay can be used to achieve multi-touch operation. However, this is still a fairly advanced and complex technology in the market. The sensing method of the illuminating power must adopt the multi-block [coltmm] and multi-row [row] matrix [Matrix] scanning mode, and can be divided into axis interleaving. Axis Intersect] and all contact-positionable [All P〇ints =d:ressable, APA] two sensing screens. The former is more practical in practice, and the requirements for computing and storage resources are lower. However, if you want 6 M403700 to achieve accurate two-touch positioning, you still have to use ApA's sensing technology. But no matter what, the current manufacturing In terms of technology, both of them need to use more advanced manufacturing technology, so the manufacturing cost is extremely high, which is not in accordance with the actual use requirements, and even more affected by the calculation, storage resources and sensing accuracy. The touch panel can only be used for mass production of small-sized panels, for industries that use medium and large-sized panels [such as notebook computers, industrial computers, p〇S systems, ATMs, medical equipment,
監視器、、遊戲機、博奕產業等等】，尚無法有效的滿 足其多點觸控的需求。 換言之 由於表面電容式觸控面板具有架構簡易、 且易於製成及低成本的生產優勢，同時表面電容式 產品更具防塵、防火、_、強固耐用及具有高 = 等優點，故如能開發出具有多觸點判定功能的表二 式觸控面板，則可兼具使用的便利性與低成本之欵。今Monitors, game consoles, gaming industry, etc., are not yet able to effectively meet their multi-touch needs. In other words, since the surface capacitive touch panel has the advantages of simple structure, easy fabrication, and low cost, and the surface capacitive product is more dustproof, fireproof, _, strong and durable, and has high=, it can be developed. The two-dimensional touch panel with multi-touch determination function can combine the convenience and low cost of use. this
