Description

200846990 IX. Description of the invention: [Technical field of invention] The invention relates to a "decoding panel", in particular but not limited to - a soft multi-touch point surface [Prior Art] Nowadays, electronic devices are provided more and more multifunctional, Reduce the cost of raw ^ dry ΐ am ° ', not to steal such as cathode ray tube displays (CRTs), the current common touch surface of the liquid can be made ί (four) ί computer input device. The way of working is usually to use a mobile 3 2 screen selection. For example, the input device includes a button or a button, a touch pad, a joystick, a touch panel, and the like. The reason why the touch panel is welcoming is that the wire is easy to operate and flexible, and the price is not lowered. The turtle panel allows the time to make the sharpening pen on the panel directly or indirectly using the cursor to make a selection. In general, the touch panel will recognize the touch control status, and then provide a corresponding action based on the touch data. There are several common touch panel technologies on the market, including resistive, capacitive, = external, surface acoustic, electromagnetic, near-field imaging. Each touch control technology has its design or configuration advantages and disadvantages. Resistive technology is to apply a thin metal conduction on the touch panel = the current is used to identify the current change and send it to the controller for processing. In the capacitive technology, conductive materials are applied to both sides of the panel, and the outer side is coated with a scratch-resistant coating film. The electrodes around the glass plate produce a uniform low-voltage electric field on the outer layer; the inner conductive layer provides electromagnetic shielding and reduces noise. Whenever a finger touches the screen, it capacitively couples with the electric field on the outer conductive layer, drawing a small current. Responsible for each electrode 5 200846990 Measure the current from all corners, and then determine the coordinates of the finger by the controller. There is no coating on the glass plate of the wave-sensitive touch screen. The conversion of the four corners of the screen will convert the signal from the controller into a wave on the glass plate, and the reflector on the four sides will generate the standing wave pattern. Once the finger is connected, some of the standing waves are absorbed. At this point, the converter will detect the phase reduction of the phase, and the controller will determine the coordinates of the finger. \ Strain gauge technology is to install the strain gauge in the four corners to determine the deflection caused by the contact of the curtain. This technology also measures the z-axis. ,field

Dispersive signal technology (DST) has been released since 2002. When we touch the touch panel, there will be a certain vibration wave in the panel, then convert this complex shock wave and calculate the actual, follow-wire The difference between the surface waves is that DST is a kind of detection in the medium, so any surface water droplets, dirt, or grease will not be detected, causing any interference, DST has no size. limits.声学 Acoustic Pulse Wave Recognition Touch Technology (APR) measures the position of the glass on contact _ in a simple and elegant way. Its _ is in the glass = mother position contact 8 ^ will produce a unique sound. The four tiny transceivers attached to the touch screen are connected to (4) the sound of the contact, which is counted by the controller and then immediately updated to the touch position with the column cursor position of each position on the glass recorded in advance. APR tests can ignore external and ambient noise because they do not match the recorded recordings recorded in advance. The above technology, such as a capacitor, can be used for detecting multiple touch points. Second, the board is a new trend in touch panels. But check these multi-touch point panels] = solid, its rigid substrate or material will weaken the mobility of these devices j in notebook, palm, mobile phones and so on. Touch J impact can make (4) device test collision _ control panel weight = ^ 装置 装置 也 也 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The components required for a hard, flexible device. A similar test is also available for *installed on a car and large display on the wall. Hard and fragile 6 200846990 g Substrate or material also increases the thickness of the product, reducing the superiority of a product on the dragon = Controlling the induction also requires the installation of a sensor on the glass substrate. These further increase the weight and cost of the instrument and the requirements of the second or seventh non-planar display or curved display. These are very expensive to manufacture and (4) the weak points can be improved in the soft multi-touch point panel. Qiao Xinyi [Invention] The present invention is a soft (flexible) touch panel, which at least includes: · one or more senses. 'The side can be plural _ step touch position, and produces a relative soft display (four) method' At least: drive - one 感 on the touch ι§; on the touch panel, the _ step touch position. Ben, Ming is also a soft (flexible) multi-touch point screen device, at least: 』 = smart user interface '· a soft multi-touch point panel combined with the above display 'mouth' can detect a plurality of synchronous touch Control position. , ^, significantly improved the problem of the past touch panel, the touch panel changed, ΪΪ, easier to manufacture, lower cost and can detect multiple points simultaneously. The invention makes the touch panel more reliable, cheaper, lighter, more flexible, more durable, more controllable, more efficient, lower in cost: easier, and can increase plasticity, light transmittance, impact resistance, and Allows contact with the knower to make the touch panel operation easier and more user-friendly. # [Implementation] Guteng Difficult to New Zealand, turn to use one or more U-use touch point soft panel. The invention is particularly suitable for a plurality of touches at the same time, and the raw or partial touch time overlaps. This is a specific case where one or more users search for a location on the same-electronic map at the same time, and the user can synchronize the control input to make the map respond. This control, double touch or synchronous touch. And the same estimate of the eight has taken up the space for heavy touch. After use, it can be rolled up for collection, and the independent signals generated by the face recognition on the touch panel can be compared to calculate the energy, energy wave, bending motion, acceleration, single electromagnetic, and the signal is measured first. Assume that the precise touch panel has a position error of the actual touch touch position and the detection _. On the side of the error range is considered effective detection. Connected and consumed: In general, the touch of the board should include three steps: touch down, and pull away. The signal measurement calculation is based on the position of the touch position;: Γ ΐ ΐ ί ϊ 残留 残留 残留 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = It is difficult to get from the background value. The change from the background value to the _ value is ii of the touchdown. Touching occurs for a limited period of time called duration. It is a hold, a painful touch: in an ideal situation, its contribution will not be terminated, or its volatility will continue to be large. As long as the time _ long, the position of the position is measured smoothly. At the end of his duties, the news is mixed (4), which is called withdrawal. Generally, the touch panel has limitations in use. Under certain circumstances, such as simultaneous touch or overlapping touch for two people is not allowed. For example, a touch-sensitive electronic map, the user will simultaneously command the map. Even though each user is used in different places on the electronic map, overlapping touch time cannot be avoided. The invention provides a flexible multi-touch panel with synchronous position detection of multiple touch points. Technologies that can be utilized by touch panels include, for example, Dispersive signal technology (DST), resistance technology, capacitance technology, electromagnetic induction technology, surface wave technology, acoustic pulse wave recognition touch technology, strain gauge technology, optical technology, or other suitable touch. Panel technology. 8 200846990 Two examples of the body are included - soft touch panel, connected - to cry.翻 Turn the panel and place it next to the fine control f or between the displays. The soft touch display is shared or can be owned independently. The soft touch panel, the control panel confirms the position of the touch, and the strength of the touch to the poor controller to the controller, and then the controller operates according to the program. Counter

Soft Ϊ 2 ί: ί = π soft, the panel can track multiple tickets, including at the same - _ stationary, tap or slide on the panel surface. Iif "can be made with fingers, palms, pens or any aids. Since ^ touch panel 1 tracks multiple targets, the user can simultaneously touch to trigger different. For example, when the user selects an item with a finger from the menu = The buckle can be a right-cursor. In addition, the maker can also = and another - finger roll the secret axis. In addition, a finger is dragging 4 == when the thief is another - target. Of course, all actions can be a touch point The above is awkward. ^ Sexual touch panels generally include _ device design to _ object proximity and / or touch. The system can be recorded. In the specific case towel, the sensor is in the whole soft The control is divided into separate areas, which are hidden, distributed on the soft touch panel, and each sensor represents an area on the panel. Shouting on a grid or - pixel array: in the Detective Touch _ send out - signal. In the simplest condition, the mother immediately generates a signal when a sensor detects a touch. When an object is detected by multiple sensors at the same time, multiple are generated at the same time. = = has soft characteristics The sensor can be made of a soft material. 1. u can have many variations for the sensor combination. The number of sensors depends on the sensitivity, softness and transparency required for the intended touch panel. To improve the sensitivity and softness of the sensing fast, it will reduce its transparency at the same time (instead, 9 200846990 (4) will generally form the county standard system on the Chi panel, while the sitting system can be a Cartesian Cartesian coordinate system and a polar coordinate system. Or other sitting ίί1 even using the Cartesian Cartesian coordinate system, usually the sensor will use X and Υ When using polar coordinates, usually use radial coordinates (r) and board I include a f test controller to be shy by sensing (Sensor) is connected to §, the communication is transmitted to the processor. The other is that the sensing controller does not process the data processing. A specific case is that the sensing controller directly transmits the location, and the processor is in the system. For example, the processor receives the data of the signal from the sensing control, and then decides how to use the data. It may include the coordinate data of each sensor and the specific case that each sensor extracts, sensing 11 itself will be Raw data. The sensing controller receives the signal from the sensor and converts the signal into a data that the processor can understand. The second sensing controller can perform the filtering and/or conversion process. The filtering process is to reduce the data congestion and make the processing. The device does not accept overloaded data. The original data is adjusted and then recognized by the processor. The conversion process can include determining the center position of each touch area.... The sensing controller can The program includes a memory component for storing the touch panel, and the program can be used to make various aspects of the soft touch panel. For example, the touch panel program may contain output values (such as coordinates) on the basis of the device. In fact, the controller Communication with the second, communication can make a bribe. The secret communication protocol is a set of rules and procedures between the numbers f. The data transmitted by the data communication protocol in the data communication protocol is transmitted in the packet. The package contains the required destination information and corrects the error data along the way. The sensing controller is usually composed of one or more microcontrollers and separately monitors one or more senses. The microcontroller may correspond to an integrated circuit that centrally monitors the sensing device and processes the signal to report the signal to the processor. A specific example, the sensing device is based on capacitive technology. When only two conductive contacts are close and there is no true JL touch, this is the capacitance that the electric field will interact to form. Such as 200846990 ί ΐ Another conductive body such as a finger. Since the object is close to the touch panel = sensor, the sensor controller can recognize more; the same time - one or more fingers and hands are applied to the touch panel. Strong force = | capacity _ device in the design of the transfer to allow for a large amount of miscellaneous, according to self-capacitance or mutual capacitance. In the self-capacitance, each of the electrodes, when the object is close to the surface of the touch panel, these objects are electrodes. The sensing controller will touch the position of the different objects in the fine electrode. In the mutual capacitance, the sensing 雷雷二: ^ ί? wire mesh, double-layered live wire can also be: therefore; sound spoon Si ΐ container. In the simplest case, 'the upper layer includes the line course: touch 2, medium, when the upper layer of the horizontal line and the lower layer == 5: one of the currents attracts the past, and the controller only = 2ΐΐίυ can be the same The position of the object touch touch panel. The board set 2' sensing device is based on resistance technology. Resistive touch surface ίί The soft bottom layer, which uses insulating materials, such as aluminum oxide or other suitable conductive coatings as the Π: Second, the Zen layer is generated through the mother layer. When there is pressure on the soft side: the two layers of love contact create a closed loop. The number of electrical cries between the two layers, iiiiχ and γ coordinates, are transmitted back to the sensing controller. The sensing control processes 11 operations. By detecting the sensor at each position. 6. The sensing controller can identify multiple objects and determine their position, waste call, L speed and acceleration. For example, the sensing shop 11 can be spoofed in the same-touch finger and palm when and when the ship and the force are small applied to 200846990. The salt barrier device allows for a large amount of miscellaneous in design and construction. For example, 2 is based on self-resistance or mutual resistance. In the self-resistance, each of the I I II I I, the early metal oxide coating underlayer, when the surface of the panel is exposed by the external layer, the upper layer is connected with the metal oxide coated underlayer to produce a closed second. road. The _ sensing controller detects the change in current in different areas between the upper and lower layers, so that 碹 = the same object _ touch position. In mutual resistance, the apparatus includes a barrier metal oxide wire mesh. In the simplest case, the upper layer includes the i layer including the line column. At the intersection of the upper and lower lines,

In the operation process, when the upper layer of the horizontal line and the lower line of the line are guarded, one of the eight parties will draw the current of the other side to form a closed mine, and the control H only needs to change the change, and then the different touches can be determined. The position of the control panel. According to Figure 3, the soft multi-touch panel can detect the position and velocity of multiple objects in the same =. This touch panel is based on a plurality of transparent sensors 3G to express different positions on the touch panel. A touch input that senses a neighboring object of one or more. The sensor utilizes a thin <wire' wire in the gap to connect to the sense controller 33. The sensors must be independent of each other, and the gap between the sensors must be as small as possible to maximize the detection area and the visual difference between the very small gap and the sensor. Second, the light, thin, and soft conductive wires 32 are in contact with the sensor to transmit the electrical signal and connect the sensor to the sensing controller. Sensing controller 31 includes one or more sensor wafers to measure the information of each sensor and report the signal to the main controller. For example, the sensor chip can convert the analog signal and transmit the digits through the discharge stream to the main controller. Any number of sensor wafers can be utilized. For example, a single wafer can be used for all sensors or multiple wafers for a single or a group of sensors. The sensor, the sensing controller, and the wire are generally materials of transmitted light. In most cases, it consists of a light-transmissive soft material such as thin glass or plastic. A better material is polyethylene terephthalate (PET), but it can be other suitable 12 200846990

Materials such as polycarbonate polyester, polyvinyl chloride, polyether oxime, polyimide imine, acid cellulose, polyethylene naphthalene, and the like. For sensors, wires and indium tin oxide (10) or conductive ink, the most suitable material is silver. This conductive ink can be applied by printing. In addition, the surface n-grain of the sense can be connected to the wire by any suitable technique. The distribution of sensations can be broad and varied. For example, the sensor can be placed anywhere on the touch surface. The sensors can be placed at random or in a certain manner. The position of the exhibition can be made up of any shape, even simple (for example, square, circular, elliptical, triangular, rectangular, polygonal, etc.) or complex (for example, random shape). In addition, the sensor ' can also have a different shape. The choice of shape is generally based on the addition of __ and the visual difference between the air and the control. According to the fourth embodiment, another specific invention example, unlike the above touch panel, is sensed to include a double-layered metal oxide wire mesh. In most cases, the lines 40 of each layer are parallel to each other. In addition, for different levels of line configuration, the intersection of the upper and lower lines becomes the sensor 41, and each sensor represents a different touch_coordinate. The sensor is used to sense the touch input of one or more adjacent objects. The upper layer provides conductive lines, and the listening layer is connected to the line (and vice versa. 3. The conductive lines are connected to the voltage source, and the respective driving currents pass through the conductive lines. That is, only the place where the contact occurs is triggered, and all other lines are grounded. They operate like a raster scan. The sense wire is connected to the sense controller, and the sense control constantly monitors the wire. Each pin is made of soft materials, such as conductive ink. When the current of the wire intersects at the node. Let the sensing controllers detect the parallel sense and the change of the current of the wire. Thereafter, the current at the other conductive line intersects at the other node, and the sensing controller detects another parallel sensed current. The change occurs. This sequence occurs until all lines have been driven and detected. Once all the lines have been driven, the drivers will reorder (repeated). In most cases, the wires are sequentially driven from one end to the other. One end. 13 200846990 t, including one or more sensor chips, respectively, measuring #唬 of different sensing lines, and reporting the results to the main controller. For example, crying = ί, Dragon Stream transmits digital data 'to the main control;. Any ί

Both Japanese and Japanese films are used. For example, a single-chip can be used for all senses, and an on- or off-chip can be used for a single or a set of sense lines. The heart, A^, and conductive lines are generally materials of transmitted light. In most cases, it is composed of glass or plastic. A better material is poly-plycol (PET), but it can also be other suitable soft materials, polyester, vinyl chloride, polyether iron, polyimide polyetherimide, a fiber. Plain, polyethylene naphthalene, etc. The sensing line, the conductive wire and the conductive layer can be printed with iridium iifiTM or conductive ink, and the most suitable material is silver paste conductive ink. In addition, the sensing daylight patches of the sensing controller can be connected to the wires using any suitable technique. The distribution of sensing lines and conductive lines can be broad and multi-lion. For example, the sense line and the guide line can be placed anywhere on the inspection panel. The thief and the conductive wires can be placed or arranged in a certain way. The position of the sense line and the conductive line may depend on the position of the coordinate. In addition, the sense and the conductive lines can be composed of any number, and the Ride _ depends on the degree of interpretation required. In addition, the number of suspects and conductive wires can be the same or different. The number of faces is generally determined by the surface area of the panel and its shape and the width of the sensing lines and conductive lines. The above is just an example of the technology used in the initial soft multi-touch panel. 'In addition to the above examples, there are many different technologies that can be used for flexible multi-touch panel, such as Dispersive signal technology (DST). ), electromagnetic induction technology, surface wave technology, acoustic pulse wave identification touch technology, strain gauge technology, optical technology or other suitable for touch panel technology. All soft touch panel technologies that can detect multi-point simultaneous touch are suitable for implementation of the present invention. The soft-multi-touch panel device is a specific example of a soft multi-touch panel. In this specific case, both the display U and the touch panel 1 are flexible. The soft display can be a small molecule light-emitting display (〇LED), high score 200846990, shed display (10) illusion, active matrix liquid not stolen, electrophoretic display, cholesterol dynamic matrix liquid crystal display, nematic liquid crystal display 2=^, horse Any display H of the molecularly dispersed liquid crystal display may be _ or 纽 or have soft characteristics and its structure may include any suitable soft beauty or ^ dimensional display. Therefore, glass, or any soft material, one of the soil can be used for f material, thin metal, thin: for example, poly-Asian, poly-display, according to image number generated on the display: = not = Cheng J It is used to test the included-users to make two touch inputs on the same panel at the same time. The multi-touch panel controller 23 _ _ coordinates The specific composition of the touch panel display device is - soft 啁 面 扳 21 cover on a soft display 2 。. Take the "Wang position _ calculation program is - calculation program, for the state of the two touch points of the second two. According to this program, at least there, the angle of the connection and the connection of two points can be calculated. In this mi is Between the line between the two points and the reference line (such as the horizontal line), = angle. In addition, because the direction of the angle should also be considered, such as - left angle, = direction of the reverse needle, can be seen as the positive direction. The New Zealand can be referred to as the angle between two points. When the two sitting points of (X Bu Y1) and (Y1, Y2) are picked up and their angles (4) can be derived from the Bis' theorem 4 In the case of 'according to this program, the 1 coordinate in the center between two points) can also be calculated. These distances, angles and intermediate coordinate values can be detected and calculated once every other period. 15 200846990 The movement sense is the time gamma crane _ control. The movement controls the characteristics of the user's touch movement, and the use of the ^ column, the crane speed, the steering angle, the acceleration, the square ^^ connection angle. For example, the distance between the two points is based on the relationship between the two points. From, the manifold is a steering == opposing display flag is built based on two points of the movable user

Based on the mobile meter # is calculated by the mobile side program, so = use touch to control the speed of the user's features, steering angle, acceleration production = program, when the distance between the two touch points and the angle, = relationship In the process of counting the nose changes, all relevant calculations need to be two. The movement speed between the two points of the user feature changes, and the basin shift = speed should also change. For another example, if the number of miscellaneous changes, the = three accelerations or decelerations change. In addition, the angle of the user's steering angle changes and changes. In addition, the position of the user feature is not changed depending on the calculation of the current center point. Shift, the control program is calculated based on the side program. Therefore, the movement control program is used to control the movement of the user's feature by changing the distance or the limb of the two touch points. The movement of the user feature is shifted. More specifically, the decoration of the feature is controlled by the motion detection and the speed measured by the equation. In addition, the rotation of the user's feature or the change of direction is controlled by the fine steering angle of the miscellaneous program. In addition, user feature mismatch is controlled by the center point detected by the motion detection program. In addition, the touch area calculation program is used to calculate the synchronization operation, the user touches 16 200846990 〒 in the product, the integration of the fine connection point, the position f technology can not be used to control the position can be applied to the hairpin month. . ° Same smoke and computing touch
