M397552 V. New description: [New technical field] The present invention relates to a sinusoidal touch panel with a transceiver for improving the sonar touch panel and its system, in particular, a transmitter and a radio wave receiver made of a plasma film a sonar touch panel system; and a writing pen that converts sound waves into electrical signals. [Prior Art] With the popularity of computers, keyboards and mice have become the most popular information input devices in the general public. However, due to their large size, non-portable tapes and the disadvantages of using programs, the development of another An input device for a touch panel integrally formed with a screen stack. The touch panel is a humanized input device that can directly input a specific area on the panel with a finger or a stylus and has input an input command. With the development trend of light, thin, short, small and complicated functions of electronic products, the space for products to be placed in input devices is very limited, and the use of touch panels can completely occupy no space, in addition to having keyboard and slide In addition to the mouse's function, it can provide humanized operation such as handwriting input, so it is the best choice for human-machine interface. According to the working principle, the touch panel can be divided into resistive, capacitive, wire and surface acoustic wave type. Among them, the resistive touch panel has the disadvantage of poor light transmittance, thus reducing the brightness and contrast of the display screen; The capacitive touch panel is susceptible to changes in temperature, humidity, or grounding conditions. The stability of the optical touch panel is poor. The resolution of the optical touch panel is determined by the number of infrared transmitting and receiving pairs. Resolution is easily limited. Due to the shortcomings of the above touch panel, there is a development of the surface acoustic wave touch panel M397552. The method of comparing the age of the face to the panel of the control panel (4) is divided into two types: · single-transmitting and single-receiving rotating wire, and the other is the array-type transmitting transducer and the array receiving transducer. . The surface acoustic wave touch panel composed of the single-emission transducer and the single-receiving transducer is excited by the transmitting transducer-surface wave, and is inclined by the angle of the multi-reflective peach panel to form an oblique angle. The surface wave of the row_board research position is different in the _(four) receiving ship, and the relationship between the scales of the __ cues is the position of the _ touch panel. For example, the beauty of the first rider, 4, 645,100, reveals the system architecture of the surface acoustic wave touch panel with the single-transmit transducer and the single-receiving function. As shown, the system includes a substrate ίο having a pair of transmit transducers T1 and T2 and a control system for receiving the transducers R1 and R2' - electrically coupled to the pair of transducers ^, each transducer (Ή, T2, R1, and R2) has a reflection contact, G2, G3, and G4 composed of a plurality of reflection units (el to en) along the path ριLu. The control system 11 generates a transmitting signal illusion, S2 ' through the -transmitting transducer switch 11a, so that the sending S2 is sent to the corresponding hair (four) energy device τι, T2 ', causing the transmitting special device to be T2 respectively The transmitted surface wave is generated along the _ path p2. Taking the surface acoustic wave generated along the path P1 as an example, the surface wave transmitted by the surface wave through the reflection grating G1 is emitted at an angle of 45 degrees with the path ρι, and is divided into n parts and 90 degrees with the road position P1. The angle is transmitted downward to the reflection opposite to the reflected thumb G1 [4 M397552 gate G2, causing the reflection units el to (5) in the reflection grating G2 to change the surface wave direction of the n portions reflected from the reflection grating Gi And causing the direction-changing surface wave to be transmitted along the path Ρ3 and reaching the receiving transducer R1, the receiving transducer R1 converting the received surface wave energy into a signal S3 and outputting it to the control system u. Amplitude detector 1 ratio. On the other hand, when the transmitting transducer T2 receives the transmission signal S2 from the transmitting transducer switch 1 la, causing the transmitting transducer T2 to be transmitted along the path P2, respectively.

a surface wave, the surface wave transmitted by the surface wave passing through the reflection grating G3 is emitted at an angle of 45 degrees with the path p2, and is split into n portions and transmitted downward at an angle of 90 degrees with the path p2 to the direction opposite to the reflection gate G3. The reflection grating G4 causes the reflection grating G4 to warm the surface wave direction of the portion reflected from the reflection thumb G3, and transmits the surface wave in the Lai direction along the path P4 and reaches the connection, and the reception transduction energy (4) Converting the received surface wave energy into job S4 and outputting it to the amplitude detector lib electrically connected to the control system. The amplitude detector lib then analyzes the signals S3, S4. Since the surface wave traveling through the receiving power If R1 is different, the signal S3 received is as shown in the second figure, and the time t ◦ is the reflection gate (2) When the reflected surface wave reaches the receiving transducer RI, the time ratio is the surface wave reflected by the shooting unit 到en to the receiving receiver R1 _ pin, and the solid line portion is the output when the user has not touched the panel. Signal. Assume that the position of the touch panel is as shown in Fig. - Fig. A1 'Difficulty _G1 reflected part of the wire wave passing along the path pv and passing through the point A1, part of the surface wave energy passing through the path Pv is partially absorbed, resulting in M397552 outputting t number S3 produces an attenuated output signal. As shown in the second figure, the output time of the output signal D1 is time t, and the time t of the user can be used to derive the touch position X of the user on the horizontal coordinate, and the output is output. The deepness of the signal D1 touches the user with the money. According to this method, the user can also push the touch position Y on the vertical coordinate, and the position of the point Α 1 can be determined by the coordinate position (χ, γ). However, in the tenth embodiment, the surface wave of the transmitting transducers ΤΙ and Τ2 passes through the η-reflection and transmission of the reflexive _ G1, G2, G3, and G4, and then reaches the corresponding receiving and rotating t* device R1. R2' causes most of the surface wave energy emitted by the transmitting transducer and the D2 to be lost, so that the output signals 33, S4 are weak, which is not conducive to the control system n to the output 1. No. Analysis. At the same time, in order to make the n partial partial surface acoustic waves reflected by the reflective grating Gb G3 have the same energy, the design of the reflective grating and the process of the substrate 10 become complicated. In addition, 'because the surface acoustic wave velocity is fast, and the time interval between time tO and time tn is also very short, the ancient text needs a faster signal processing speed' and thus requires a higher efficiency A/D converter' because of the higher efficiency A The /D converter is expensive, so the cost of the touch is greatly increased. On the contrary, if the cost of the touch panel is increased, only the resolution is sacrificed. - Furthermore, as shown in the third figure, U.S. Patent No. 3, (10), No. 327, which discloses a surface acoustic wave type touch panel of an array type transmitting transducer and an array receiving transducer. Department, bribe. Referring to the third figure, the two adjacent sides of the flat panel 2A of the touch panel 20 of the age towel are provided with a plurality of side-by-side transmitters a, 22 and two adjacent panels 20a 3 There are also a plurality of parallel connections (four) 23, % on the side opposite to the row of transmitters [M397552, respectively, and the plurality of transmitters 21 and the pair of receivers on the opposite sides respectively Correspondingly, the emitters ^ correspond to the opposite receivers 24 on the opposite sides, respectively. The emitters 2 22 respectively generate parallel surface acoustic waves 25, 26 along the X, Y machine over the touch panel 20 to form a detection matrix on the plate 2A. 'Please refer to the _, which is a cross-sectional view of the surface wave applied to the touch panel 2G. As shown in the figure, the emitter 21 is composed of a piezoelectric crystal 仏 and a synthetic transparent tree _ lipid 21b. The receiver 23 is composed of a piezoelectric crystal and a synthetic transparent resin. In operation, the driver 27 transmits an electrical signal to the piezoelectric crystal to generate a shock such that the synthetic transparent resin 21b generates surface acoustic waves and is applied along the flat plate to the other end of the synthetic transparent resin to generate a shock. The transistor gamma transmits the vibrational transformant to the generalizer 23, and the fine reading and Μ are transmitted. The control system 3G performs signal analysis processing. When the user points the tablet, the surface waves 25 and 26 transmitted on the plate are blocked, that is, the energy of the surface wave is absorbed, so that the control system 3G calculates the user's touch position. However, the touch panel formed by the array type transmitting transducer and the array receiving transducer will make the structure of the touch panel more complicated, and the resolution and signal analysis and processing methods of the touch panel are interest_. Moreover, the resolution of the control panel is the same as the pitch of the transducer, so that high resolution products cannot be obtained under the limitation of the process technology cost. Therefore, how to provide a surface acoustic wave touch panel system which can improve the resolution and processing speed can avoid the problem of the lack of the prior art. According to the shortcomings of the above-mentioned prior art, one of the objects of the present invention is to provide a stylus pen type touch panel and a system thereof which can improve the processing speed of the south. ‘ ^
