Description of the Invention: [Technical Field] The present invention relates to the field of touch panels, and more particularly to a function of determining the relative movement of a plurality of input contacts of a scanning touch panel to obtain a positional touch panel. Apparatus and method. [Prior Art] Conventionally, the input of an electronic device is based on a keyboard and a mouse, and cannot be made in a human intuitive manner. After that, the touch panel has been widely used in various types of electronic devices. At this time, the user can input the contacts by means of a hand or a touch pen and a screen thereon, and the sensing device provided under the screen at this time. The position of the contact input is sensed for the purpose of operating the touch electronic device. Touch panels can be classified into resistive, capacitive, surface acoustic (saw) and infrared (IR) touch panels. & even the 'touch panel' can be more user-friendly way to represent the user's work = time to make a specific gesture on the screen, that is, the specific relative movement between the fingers, so It is convenient for the system to enter in a more intuitive and intuitive way: the function of the input, without the need for various user graphical interfaces ((10)), the special function can be window zoom and panorama function. = The phase _ is, in order to achieve the multi-point input function on the touch panel, the dynamic situation Γ, the mouth-measuring device does not need to be able to sense the relative movement of the input points on the screen; In the case of the relative movement of the day, the corresponding work m of the person to be input is used to determine the corresponding work m. The position sensor 5 of the contact input of the sonic and infrared touch panels can be found in the first figure (including A, B, 〇 and D) and the second picture (including A, B, C). Schematic description of D and D). As shown in FIG. 1A, a surface acoustic wave touch panel 10 includes a screen area n and a component setting area 12, wherein the screen area n is located at a central portion of the touch panel 10, and the component setting area 12 surrounds the screen. The area ii is located in the vicinity of the touch panel 10. The component setting area 12 includes a first transducer 13a, a second transducer 13b, a third transducer 13c and a fourth transducer 13d, and includes four sets of partial reflections and portions of the signal wave. The transmissive reflective elements 14a, 14b, 14c and 14d are arranged along the four sides of the screen area 11, respectively, wherein the first and second transducers 13a and 13b It is disposed along a horizontal axis X of the touch panel 1 , and the third and fourth transducers 13C and 13 d are disposed along a longitudinal axis γ of the touch panel 1 , the four sets of reflective elements 14 a , 14 b , 14c and 14d are both disposed along the horizontal axis X, and the other two Ha and 14b are disposed along the vertical axis Y. In the continuous operation, an electric energy signal Signal__Ei 1 is sent into the first transducer 13a on the horizontal axis X of the touch panel 1 , and the first transducer 13a then converts the electric energy signal Signal__Eil into a vibration wave. The signal signal_V1, the vibration wave signal Signal-VI is then semi-traveled and semi-reflected along the reflective element groups 14a and 14b (as indicated by the corresponding arrow A1), and finally received by the second transducer 13b, and the received signal is received. The vibration wave signal Signal-VI is converted into an output power signal signal_Eol. Similarly, an electrical signal Signal_Ei2 is sent to the first transducer 13a on the horizontal axis X of the touch panel 1b, and the first transducer 13a then converts the electrical signal Signal_Ei2 into a vibration signal Signal_V2, which The vibration wave signal Signal_V2 then travels along the reflective element groups 14c and 14d (as indicated by the corresponding arrow A2), finally receives the second transducer 13b, and converts the received vibration wave signal Signal_V2 into an output power signal Signal_Eo2. . Among them, the horizontal axis X and the vertical axis Y are opposite to each of the transducers 14a and 14b and 14c and 14d, which are operated at different times, so that the vibration wave signals Signal-VI and Signal-V2 do not interfere with each other. Since the four sets of reflective elements 14a, 14b, 14c and 14d have partial reflection and partial transmission capability of the signal wave, the vibration wave signals Signal-VI and Signal V2 are partially reflected to be the second and fourth transducers 13b, respectively. And 13d received, so the output electrical signals Signal_E〇1 and Signal_E〇2 received from the second and fourth transducers 13b and 13d at this time are as shown in the first B diagram, wherein each output power signal is out. At different times t, the time required for each of the sets of reflective elements 14a, 14b, 14c and 14d to reflect the vibration signal Signal_V 1 and Signal_V2 to the second and fourth transducers and i % is different. As a result, Vy and Vx* represent the voltage values of the output power signals Sig(10)L Eol and Signal_E〇2, and are respectively related to the horizontal axis coordinates and the vertical axis coordinates of the contact input point. In addition, the time when Vx appears is longer than the time when Vy appears. The path experienced by the vibration wave Signal-V2 at the position p of the object is longer. In addition, the set of reflective elements 14a, 14b, 14A, and 14d are formed from the corresponding transducers, 13a, 13b, 13c, and 13d, and are relatively dense, which is due to the vibration signal Signal. A VI and Signal-V2 have to be compensated as the signal increases as the path of travel increases. When an object (such as a user's finger or a pen) touches a point p on the screen area u, the vibration waves Signai-V1 and Signal-V2 reflected from the reflection group 14a and 14c are shielded by the object and cannot be transmitted. Up to the corresponding second and fourth transducers 13b and 13d, the waveforms of the electrical energy signals output by the second and fourth transducers 13b and the stimuli are as shown in FIG. Compared with the picture _B, Vy and Vx in the picture c have a lower voltage output at a specific time, which is the vibration wave SignaLVi A Signal_V2 is blocked by the object at the position of the object and cannot be The second and fourth transducers 13b and 13d are received, wherein the time when the vx appears lower than the 200849070 output voltage is later than the Vy is due to the longer path of the vibration wave Signal_V2 at the position p where the object arrives. In addition, Vy and ¥\ have a sharp wave at the beginning, which is the input power signal Signal_Eil and Singal-Ei2, which are directly transmitted through the second horizontal axis reflection unit group 14d and the second vertical axis reflection unit group, respectively. 14b is caused by the reception of the second horizontal-axis transducing element 13b and the second vertical-axis transducing element. When a multi-contact (not shown) is input to the screen area u, the corresponding voltage values Vx and Vy of the output power signals Signal_Eo 1 and Signal-E〇2 are as shown in the first d-picture. As shown in FIG. 2A, an infrared touch panel 2 includes a screen area and a device setting area 22, the screen area 21 is located at a central portion of the touch panel 2, and the component setting area 22 is surrounded. The screen area 21 is provided, and includes a first group of infrared light-emitting elements 23a and a second group of infrared sensing elements 23b, and a first group of light-emitting elements 24a and a second group of light-sensing elements 24b. The infrared light-emitting elements 23a and 23b may be infrared light-emitting diodes (LEDs) or the like, and the light-sensing elements 24a and 24b may be photo sensors or the like. In actual operation, the first and second sets of infrared illuminating elements 23 & and 2 发射 emit infrared IR1 & IR2 at different times, respectively, so that the corresponding light sensing elements 2 are rushed to receive 24b, and the light sensing elements 23b and 24b are The received infrared ray and IR2 are converted into corresponding output power signals Signal-E〇1 and e〇2, and the corresponding output voltages of the output power signals Signal-Eol and Signal-Eo2 are as shown in the second B-picture. , gP Vx and Vy, which is equivalent to that shown in the first B diagram. If an existing object touches a point p on the screen area 2, the infrared rays associated with the input point p are blocked by the input point P and cannot be received by the light sensing elements 2讣 and 24b, so the output power signal Signal Eol And the corresponding output voltage of Signal-Eo2 Vx and 200849070
