Description of the Invention: [Technical Field] The present invention relates to a touch panel, and more particularly to an improved touch applied to a portable electronic device. [Prior Art] There is now an input device 4 for the completion of the electronic (4) device. Some operations correspond to moving the cursor and making corresponding savvy on the display screen. For example, the input 3 includes a button, a switch, a keyboard, a mouse, a trackball, a touch pad, a joystick, and a touch screen 4. Each of these devices has its own advantages and disadvantages and must be considered when designing consumer electronic devices. On portable computer devices, the input device is typically selected from buttons and switches. Buttons and switches are mechanical in nature and provide limited control over cursor movement and selection. For example, we are generally used to move cursors in a specific direction (for example: the arrow key field to make a specific choice (such as RETURN or E earn R, delete, digits, etc.). In the palm personal digital assistant (P_nalDlgltal) In the case of Assistants 'PDA for short), the input device tends to use touch sensitive ^ display = screen. When the screen is touched, the user uses a stylus or a finger to directly point to the display object on the screen to make a floor on the display screen. The knee is calculated by the fresh-laid device, and the input device is generally used as a board. When the surface of the touchpad is moved by touch, hand & /D, the transmission of the device (special standard) corresponds to the use of the s The motion track of S. § When the tapping of the touch panel © one or more taps on the surface of the touch panel is detected, the electrical signal converted by the touch panel © can also be selected on the display screen. In some cases, Any part of the touchpad can be tapped as a selection confirmation key, and in other cases, the special section of the touchpad can be generalized _ touch the Wei. In addition, the board can provide a special role area. Put your finger on the side When the gamma direction sweeps through the active zone linearly, it completes the reel. With this technique, the movement of the vertical reel is achieved by moving the hand in the gamma direction (forward or backward) in the active zone, or The horizontal scroll is implemented in the X direction (left or right). For the touchpad, one-dimensionally used by the Karl coordinates c〇〇rdinateS) to monitor the finger movement when the one-dimensional one is defined by the Cartesian coordinates as two-dimensional coordinates. (X y), the coordinate of the I point (the position where the finger is located) is the distance from the perpendicular line of the two intersecting points. For example, the vibration detector of the touch panel can monitor the coordinates of the finger or other contact material (x) , y) bit f, then control the input of the 201013474 circuit, x, y position and move the input indicators on the display screen. In order to make the touchpad more compact, the touchpad has one or more Sensors for measuring the proximity of the fingers, these sensors are scattered on the touchpad, each sensor represents a χ, y 軚 position. In most cases, the sensors are arranged in columns and rows Grid. So when the finger is touching When the grid of the detector moves, the sensor generates a control input indicator in the display screen _^^ refers to the position of the mobile secret mine. For the rest of the _ domain, the new resistance sensing technology is carried out, but it should be noted that Other technologies have similar characteristics. [Summary of the Invention] ❿win's strip provides - Lin touches the size of the singularity of the singer and controls the iii system to complete the different control functions. The pressure sense is controlled by the clever plate = layer and 7 coordinate layer; the x coordinate layer is generated and mapped to the corresponding Cartesian coordinate II I coordinate layer to generate the corresponding Cartesian coordinates (x, the value of y in the force; The amount of pressure applied by the stylus or other force applicator can change. Pj Wendian and 赝- kind of system combined with a touch panel with pressure sensing characteristics, which mainly converts different impedances on the touch panel into corresponding electrical signals The following beneficial effects are as follows: the force control function of the touch panel in selecting the positioning function can be realized by external control circuit with the touch panel. [Embodiment] In the following description, the present invention is fully described in order to make the present invention more completely embodiment. Declared. In some embodiments, it is known to those of ordinary skill in the art, that is, not to be described in detail. , returning to the layer; basic, including the coordinate layer 10 and the first conductive layer 2〇y 'the first - 曰 /, the middle && layer includes the first - resistance y block k layer 匕 (including the 苐 - guiding layer 40 and The second resistive layer 5 〇 7 201013474 The first resistive layer 10 shown in the eighth figure is a substantially square lamella, and the conductive material is changed by a conductive yoke such as pressure, elongation, bending or a combination thereof. =^!1 The composition of the conductive machine - generally carbon - such a structure is a common structure, of course, can also be replaced by other types of conductive materials with the same conductive properties. - The layer 2G is composed of a first metal wire electrode 21 and a second metal wire electrode ,, and the metal varistor layer 30 of the miscellaneous 21 and the second gold material (four) pole 22 are both inconsistent a substantially square flaky shape that changes its mechanical deformation by pressure, extension, bending, or a combination thereof (the granular nickel-willows are made of clear material than the voids (for example, a large number of layers will be carried, wherein Volume ratio),:=22:Two changes=People's fingers, can also come from the pressure of the stylus to cause 1 mechanical deformation. The external force can come from the non-conducting characteristics, the force and pressure are infinite. The base is gradually reduced, and the conductive property is gradually enhanced. The resistance value of the variable resistance layer 30 will be composed of the third gold=jina 42 composition, and the electrical material composition. 、, _42 are conductive metal I good metal guide The two-resistance layer 50 is roughly a square lotus y, which is a force, an extension, a f-curve or a combination thereof, and the characteristics are not mechanically deformed (for example, the house is generally carbon, and the age of the squadron is smashed, The conductive material of the electrical properties of the electrical material is replaced by the conductive material. When the other types of the same conductive protective layer 60 are substantially in the shape of a square sheet, the other force applying element 60 is protected from the direct contact with the other force applying element. The force 60 does not have conductivity. The second resistive layer 50, the protection The layering plate ===::: composition, the top outer layer of the touch protection layer 1 of the present invention will be described in detail, and the two opposite electric powers are turned on. The first and second electric 8 201013474 products are larger than the first resistor.

On the upper, the variable resistance layer is prepared; ^ when the user's finger is pressed against the touchpad or an external force is applied and varies with the pressure Corresponding to the change of m external force after the resistance is like - the rate is reduced to reduce the voltage of the electrical circuit _, pass H, guided · _ Wei Wei 30 is the first-conductance detection circuit, which can detect ^ H, the wire electrode 21 and the second metal wire electrode 22 to be connected to the first-conducting towel = value m 憧 value or _ small. The difference in the position of the force applied to the touch panel 1 is not fixed, but a current or current value can be determined by the external force at the first metal wire electrode 21 through the circuit, and if the touch panel j is regarded as a known line The voltage value of the electrode 22 corresponds to the voltage value or the current value of the Cartesian coordinate (X, y) 'the same principle, and the second tomb is in the threshold of the Karl symbol (x, y).

The specific location. The variable resistance layer 3G to be emphasized here can change the magnitude of the resistance value according to the magnitude of the pressure applied thereto, and thereby change the magnitude of the voltage value or the value of the current flowing therethrough. In the variable resistance layer 3 of the touch panel of the present invention, the resistance value of the variable resistance layer 3 减小 is reduced as the external force is applied to the touch panel 1 , that is, the pressure of the user's finger is increased, and the variable resistance layer 30 is The larger the voltage value is, and the voltage value can be continuously changed as the pressure continuously changes. Through the external control circuit, the continuously changing grinding value can be converted into a continuous or intermittent electrical signal, thereby controlling the corresponding external equipment. Power can be. Therefore, the touch panel of the present invention is actually transformed into a three-dimensional Cartesian coordinate x, y, z) which is capable of both positional positioning and function (4) in accordance with the change in pressure, by the two-dimensional Cartesian coordinates & Wherein, the coordinate value fork and y are used for positional positioning, and the coordinate value 2 is used to represent the pressure value. Referring to the ninth aspect, the present invention combines a line having a pressure sensing characteristic panel, and further includes a control circuit that can convert different impedances on the touch panel into corresponding electrical signals; function control software, The function control software is used to judge the electrical signals of the control circuit, and the different electrical signals are correspondingly implemented to perform different functions corresponding thereto. In an embodiment, as shown in the tenth, eleventh, and twelfth figures, for example, the mobile phone or the mp3 needs to adjust the sound size in the song playing mode. In the past, different control buttons are required to perform the operation. Adjust up and down. However, in the case where the touch panel 8 of the present invention is integrated, the adjustment becomes more convenient and user-friendly. The wire finger 7 is tapped on the touch panel 8 with a constant force, and the force is applied downward to determine a reference force. Different magnitudes of force may generate voltage or current values of different magnitudes, and are provided to the control circuit as a reference value. Then, according to the magnitude of the reference force, the user applies a greater continuous or medium force to the touch panel 8 to control the volume amplification, as shown in the tenth-figure; or apply a smaller continuous or interrupted force to the touchpad to control the volume reduction. Small, as shown in Figure 12. For example, in the GPRS (General Packet Radio Service) navigation mode, the mobile phone needs to adjust the size. On the mobile phone integrated with the touch panel 8 of the present invention, the finger 7 is first used on the wish board 8 to lighten the force or press the force to determine a reference force, thereby determining a reference voltage value or "electrical value" and then the user applies a greater continuous or medium force to the touchpad 8 based on the magnitude of the reference force to produce a voltage greater than the reference value Or current to control the map zoom, as shown in the thirteenth figure; or apply a smaller continuous or interrupted force to the touchpad 8 to generate a current of less than the reference value of 201013474 to control the map reduction, as shown in Figure 14. In another type of implementation, for example, the mobile phone is in the number input mode, the different number input part on the touchpad 8 can input different 0 to 9 number keys by inputting different strengths, and the mobile phone is in the standby mode. Next, using the finger & other input member to press the digit button with a normal pressure, the digit corresponding to the digit button can be input; and the pressure is greater than the normal = degree The word key, the corresponding digital key can correspond to other functions, respectively: This can include directly entering a function menu (such as SMS function, phone book), open a function software game, network browser ), or directly call a user. As shown in the fifteenth and sixteenth figures in the mobile phone number input mode, there may be another implementation example: when the user's finger 7 slides on the touchpad 8, the panel is given 8 a certain pressure, the ^ force is smaller than the above-mentioned normal pressure, and will not be in the number input mode · digital input function. However, the pressure can also cause the resistance value to change on the variable resistance layer, and the variable power is judged by an external circuit. It can generate the corresponding sound lockback signal. For example, when the user frequently uses ^ dialing, it is necessary to observe the touch panel 8 at the same time with the eye, so as to accurately press the area corresponding to each digit on the touch panel 8, and the operation mode is complicated. As described in the embodiment, when the user's finger 7 slides on the touch panel 8, if the finger moves to the area corresponding to the number key "!", the slight pressure of the finger triggers the external power.瞒The corresponding voice signal, the mobile phone will _digit “丨,, the corresponding voice prompt, you can know, refer to the seventeenth figure, if the finger moves to the number key “3, then the phone will return the corresponding voice prompt, In another embodiment, for example, in the mobile phone GPRS navigation mode, as in the seventeenth figure and the second circle, the fine position is not required to be adjusted, and the entire job board 8 can be divided into a plurality of regular shape regions. 'The user presses a certain area in the divided area with a finger 7 with a certain force, and the area corresponds to the miscellaneous amount of the touch panel 8. The broken line should be mixed with the financial direction. ' The above embodiment is only the touch panel of the present invention. There is no other embodiment of the various embodiments, and there are other embodiments that are not exemplified. It is necessary to describe here that a mobile phone or other electronic device implements a related function by using a touch panel with pressure sensing function having the foregoing method. Both are within the scope of protection of the present invention.
