Male f) 512274 A7 V. Description of the invention (>) and the visibility (visibility) of the image are reduced. In contrast, Xihe ’s wave-type touchpad is designed to ensure a strong touch surface and High display image The quality can be used favorably. Because ultrasonic waves are used to detect the coordinate data related to the input position, there is no need to form a resistance layer on the soda glass substrate, and no plastic cover is needed. Soda glass is quite transparent and is used to Supports the transmission of ultrasonic waves. The soda-lime glass is the substrate material of the conventional acoustic wave touchpad. The end-users will become a piece of window glass when viewing this acoustic wave touchpad optically and mechanically. Representatively, 4% of the incident light is reflected by the surface of each glass, and the maximum light transmittance is about 92%. The reflection of ambient light will reduce the apparent β and contrast of the image. The reason for these reflections is air The refractive index does not match with the glass substrate. The decrease in light transmittance reduces the brightness of the image. When a touch panel is placed in front of a display device where the brightness (brightness) of the liquid crystal display is relatively low, it becomes It has a significant effect. Conventional methods for reducing reflection and increasing transmittance include optical bonding or anti-reflection coating. These methods are used to deal with the gap between air and glass. Refractive index mismatch. These methods must improve the inherent transparency of the substrate material itself. Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) Soda-lime glass is not completely transparent. The main reason is that iron ion impurities produce colored centers. These ion impurities can reduce the transmittance of light and distort the color of the displayed image. For example, the difference between the optical type of the acoustic wave type and the resistive type touch panel, There will not be a profound impact. However, the improvement of the transmittance of lime glass in general is very beneficial to the improvement of the optical quality of the acoustic wave touch panel.

B7 V. Description of the invention U) The touchpad is used to cause attenuation of one of the chirped beam shots. After determining / confirming the corresponding transmitter / receiver, it is used to obtain the coordinates of the touch. The acoustic wave touchpad shown in the specification of US Patent No. 3 G 7 3 3 2 7 uses the modified wave as a "Rayleigh" (Ray 1 e i g h) wave. These Rayleigh waves can be transmitted from one edge of the touchpad to the other edge. However, it should be noted that this type of acoustic wave touchpad requires multiple converters (transducers) and the associated wire conductors and electronic channels (communication paths). This type of plastic wave sensor is expensive because it is provided with multiple converters and cannot be commercialized. The following explains the commercialized sonic touchpad. One of the leading patents in this field is the one described in the reissued "Patent US Patent No. 35151" by Adler. Acoustic converters generate cluster (sequence) waves, which are coupled to a base plate. These sound waves are directed to the grid array (array) via the sound wave re-direction, and are biased 90 ° toward the active area of the array. The direction indication grid is oriented to be printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). The transmission axis of the sound wave of the converter forms an angle of 45 °. These grids are similar to some silver-plated mirrors in the optical system. The sound waves passing through the active area pass through the other grid columns and then indicate the direction toward the output converter. The coordinates of the touch position are determined based on the analysis of the selective attenuation of the received signal in the time zone. Various characteristic delays correspond to the coordinates of the touch on the surface. The use of the grid array can greatly reduce the number of converters required, and thus can make a touchpad that is commercially competitive in price. The downside is that the use of grid columns can greatly increase the extremely large distance that the chirp wave must pass through the substrate. This paper size applies the Chinese National Standard (CNS) Λ4 specification (210 × 297 mm) 512274 A7 B7 V. Description of the invention U) The signal amplitude of the 触控 wave-type touchpad is further improved due to the low efficiency in the scatter of the grid columns. Decrease. This inefficiency can be minimized through proper array design. By orienting the lattice elements at an angle of 45 ° and making their spacing an integer multiple of the wavelength of the acoustic wave, effective correlation scatter from the array can be achieved. When equalizing the sound wave power in the active area, the sound wave energy can be used very efficiently. The conventional method is to correct the tendency of the signal amplitude to be attenuated by an exponential function (a function of delay time). According to the method described in the 11th ellipse, the 37th to the 41st line of the US Patent No. 4 7 4 6 9 1 4 specification, the equalization of the signal is achieved by arranging the grid (also the reflective element; ), Set reflective elements with different heights. An alternative method is to selectively omit the grid elements to generate a substantially constant acoustic power density covering the active area. In this case, the grid spacing decreases as the distance from the converter along the array axis increases. By using these conventional methods, it is possible to avoid unnecessary inefficiencies when the wave direction is re-directed. However, using the 2nd direction of the chirp of the grid array indicates that signal loss is inevitable. Therefore, the importance of minimum signal amplitude requirements for chirped touchpad design will increase. Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) The commercially available electronic devices for sonic touchpad products are based on US patents such as Brenner The basic concepts suggested in the instruction No. 46441QG. This patent case has an improvement on the reissue of the specification of US Patent No. 3 15 15, in which the received signal is compared with the reference signal pattern recorded in the billions to obtain the received signal. Disturbance (disorder). After analyzing both the time delay and the signal disturbance, use the touch of 磬 waves to determine the position and scale of the VIA touch (the size of the paper is applicable to the Chinese National Standard (CNS) Λ4 gauge (210 × 297 male f)) 512274 A7 B7 V. Invention Description (A) Small) Both parties. When proper operation of the touch bar is to be performed, in order to avoid the disturbance of the signal caused by the wave-absorptive touch and the signal change caused by the noise of the electronic bar and the noise caused by the bar of the electronic bar The resulting signal change is unclear, so a large SN ratio is required. Noise from electronic bars is caused by basic noise from circuit components and by electromagnetic interference. In recent years, the market is expected to have light touch and fast touch response, so it is required to have a lower touch disturbance threshold, and therefore a higher S / N ratio is required. This Attler-type chirped touchpad is more commonly found in the aforementioned patents and US patents No. 4 G 4 2 4 2 3, 4 6 4 4 1 0 0, 4 5 4 5 8 7 No. 0, 4 7 0 0 1 7 (Nos. 5 and 4 7 9 1 4 1 6. For each coordinate axis to be measured, chirped waves are generated in a glass substrate by a transducer containing a piezoelectric element. That is, The packets of the transmitted wave are scattered along the axis of the transmission reflection array. After cross-cutting the substrate, it is recoupled through another reflection grid. It is printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back first) (Fill in this page) It becomes a wave transmitted in the direction of the axis, which is antiparallel to the initial transmission wave and is transmitted toward the receiving converter. The wave packet is dispersed along the path of the substrate and is dispersed over time. The waveform is transformed into an electric signal and processed. The time delay of the disturbance of the electric signal corresponds to the distance before the chaotic component of the wave. In this way, according to the system, two converters are required for each axis. The typical method is Determine X and y coordinates; the determination can Use a total of 4 値 converters to implement. Reduce the number of converters can also implement the above-mentioned deflection of the sonic touch panel. The wave is near the green part of the substrate parallel to the axis of the reflection grid, and its The line part is reflected by 180 ° and passes through the substrate ~ 8-This paper size applies the Chinese National Standard (CNS) Λ4 gauge (210X 297 male f) 512274 A7 B7 V. Description of the invention (7) Return to the reflection array, and again Reach the path towards the converter. In this situation, the converter is constructed to periodically perform actions on both the transmitter and receiver at the appropriate time. In a way that determines the two coordinates of the touch, the vertical The axis is provided with a second converter, a reflection array, and a reflection edge. In addition, the other system is to prepare a single converter to generate waves for the detection of two-axis touch, and to receive waves from two axes. When When the number of converters is reduced, the length of the corresponding wave path of the touch panel will increase. Therefore, the signal loss due to the sound wave attenuation of the substrate material will be large. Touching can be performed by pressing the surface with a gloved or non-gloved finger or the pen tip. It can also be actuated indirectly with the finger or the pen tip through a cover sheet covering the surface of the glass substrate. (Please read the precautions on the back before filling this page) Ultrasound has several modes in the glass substrate. The mode known as "Rayleigh" wave is of particular interest in acoustic touchpads. The essence of Rayleigh waves It is limited to a single surface formed by a homogeneous non-piezoelectric medium with a very limited thickness. Rayleigh waves numerically calculate the wave function related to this mode for semi-finite media. It is guided to a medium with a limited thickness. Such a wave near a surface should be properly called a "quasi-endurance-like" wave, and such a wave is generally called a "Rayleigh wave", which is also called in this specification. Practical experience in the design and manufacture of the touchpad shows that the thickness of the substrate at about 4 times the Rayleigh wavelength is sufficient to transmit Rayleigh waves well. Other wave modes have been picked up using sonic touchpads.

Description of the invention 〇- / 〇- Si plus 2 値 Na + ionSimilarly, as a result of the addition of CaO or MgO, the common binding is cut off, and becomes Si-0- / 0-Si plus 1 痼 of C a 2+ or M g 2+ ions. In this way, a large amount of "pin" or "lime" can be used to make crystalline quartz into an amorphous glass. Migration from crystalline materials to amorphous materials results in increased attenuation. For example, you can refer to section 1 of Pyer XV (published by: Mass ο η) in volume 1 of the textbook of phonology (Ondes elastiques dan les solides) of Royer and Dieulesaint, as follows: The solids used in applications that require higher frequencies (for example,> 10G Μ Η ζ) are crystalline. Because it is stipulated that the material is transmitted by mechanical vibration, the attenuation of such vibration is small. That is, since glass of an amorphous material is used instead of a crystalline material such as quartz, the acoustic wave loss is inevitably increased as a result. Printed by the Consumers' Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (read the precautions on the back before filling out this page) The unexpected findings of the inventors, etc., have shifted to an amorphous glass state. When a sufficient amount of silicon dichloride is added, For various compounds, the effect of chirped wave attenuation varies greatly. Among several glass compositions, soda-lime glass can be seen to intentionally reduce chirping losses. In addition, some patterns were observed. If the additive is replaced by Si-0-Si shared bond with a weak ion bond, the sound attenuation will be relatively large. If the additive is used to replace the common bond, strong ion bond or sterically bound ion bond, it will be used to replace S i- When 0-S i share the combination, the attenuation of the acoustic wave is relatively small. The addition of Β 2 〇 leads to the combination of B-0-S i, but will not cause the breaking of the common combination mesh-1 3-This paper size applies the Chinese National Standard (CNS) Λ4 Regulations (210X 297) 512274 A7 B7 5 , Description of the invention (>) bad and the destruction of Si-0-/ 0-Si. This is an example of the establishment of a substitute union. Positive ions with a high charge state of 3 or more, such as the addition of A 1 3 + and Z Γ 4 + have strong ionic binding, and the chloride ion S i- (T formed at the end of the binding chain is stronger than the highly charged ions Ion binding. This kind of ionic binding with ions with a high charge state is very strong because the charge of the ions related to the electrostatic binding force is strong. Strong ionic binding will cause the Si-0-S i common binding to be destroyed. In the case of X 2 0 3 or X 0 7 type additives, should the element X be used to replace the common bond X-0-S i, or the element X to form a highly charged ion X 3+ or X 4 + I do n’t know. But in any case, the result is the same. The mesh of molecular binding becomes stronger when compared with X 2 0 or X 0 type additives. The reason is that the net is not in order, but it is caused by It can be observed from experiments that the attenuation of chirped waves is reduced. 1 (20 and {}? 10, which are the same as Na20 or CaO and MgO, have X2O and X0 types, but the equivalent ionic radii are greatly different.

These ions are all attracted by the negative charge of the negative oxygen atom at the end of the common mesh. However, when comparing the Na 4, Ca 2 + and M g 2+ ions, because K + and B a Μ The size of the ions is large, so the use of the cut-off common area of Si-0-/ (KS〗 to fill the space will have a three-dimensional effect. The explanation of this observation and discovery by the inventors of the wood is that when the radius of the ions exceeds At about 2 o'clock, this three-dimensional effect can suppress the attenuation of chirped waves. -1 4-This paper size is applicable to Chinese National Standards (CNS) Λ4 gauge (210X 297 cm) 512274 A7 B7 V.

W 〇 9 6/2 3 2 9 2 based. Borosilicate glass was developed by Pottery Corning and sold on the market by the company Corning under the trade name "Bailix". The price of this glass is higher than that of soda lime glass, but it is mainly because it has a small thermal expansion coefficient, can withstand large temperature gradients, and does not break, so it can be found on the market. At present, Schott glass company also sells borosilicate glass on the market under the trade names of "Dianbacks" and "Brofrote". In simple experiments, it can be shown that the Rayleigh wave absorption of borosilicate glass is only about half that of soda-lime glass. Figure 3 shows the method used to determine the attenuation of Rayleigh waves in glass. The pair of the transmitting converter 2 and the receiving converter 4 is mounted on glass, and the intervals between these are changed to 2 o'clock, 4 o'clock, and 6 o'clock. Measurements were performed at various intervals on the 2 値 sample of the lime glass and the 2 samples of the borosilicate glass. In this case, the borosilicate glass uses a Dianbach glass sheet manufactured by Sch 〇 11 and the results are shown in the graph of the fourth circle.

The attenuation of soda-lime glass is 1.4 4 dB / hour ((KSYdB / em), and the attenuation of borosilicate glass is 0.74 dB / hour (0.3 d B / cm)) The glass substrate of the present invention includes a substrate or a substrate.

This increased supply is at least on the table and has nothing to do with the choice of substrate material, and can achieve multiple purposes. It can be enumerated below. (1) The increased S / N ratio can reduce the cost of the electronic control device related to the touch panel. In particular, by reducing the cluster amplitude to, for example, a transistor-transistor-logic (TTU voltage level), the cluster circuit of a control device for transmitting a signal cluster to a signal converter of a touch panel can be made. Simplified, can use lower cost circuits in the output stage to reduce the amplitude of the cluster. -18- This paper size applies the Chinese National Standard (CNS) Λ4 specification (210X 297 mm). 512274 A7 B7 5. The invention description (β) hours can reduce the EM I released from the control device for its advantages. (2) The re-issued US Pat. Because the number of converters and electronic channels is minimized, and the reliable and accurate analog measurement is performed based on the time of the touch position, a reflective array is used. However, the relatively longer sound wave path length of the result will be 2 times. The scattered waves cause losses, and the amplitude of the received signal becomes smaller, and the overall size of the touch panel is limited. The increase in the SN ratio obtained by using the glass of the present invention can be used To increase the overall size of this type of touchpad. For example, a rectangular touchpad can have a diagonal size of at least 21 o'clock. (3) Usually between the sharp part of the touchpad and the adjacent object Contact is to be allowed. In order to protect and surround the reflective array and the converter, the shell or groove of the touch panel CRT forms a wave-type touch panel contact. This type of connection can be carried out by using an RTV seal to make the touch An elastic seal that does not leak water between the control board substrate and adjacent objects. Since this seal absorbs acoustic wave energy, it is best to use a seal that can significantly increase the SN ratio. (4) In many applications, to ensure contact The proper mechanical cooperation of the control panel to the touch / display bar system, so the amplitude of the chirp signal is sacrificed to optimize the mechanical design. The mechanically miniaturized converter can be designed below the best chirp performance. In order to cope with mechanical constraints, the reflective array can be designed to be narrower than those that achieve the best performance. In order to reduce the signal loss due to attenuation in the substrate material, the design engineer has more flexibility The signal vibration of the animal signal is used to improve the mechanical fit.

512274 A7 B7 V. Description of the invention (j) Lime glass has become the material of choice for sonic touch panels. As mentioned above, specific glass can improve the Sn ratio while obtaining the advantages of these mechanical and optical types. The most important wave mode of an acoustic wave touchpad is the Rayleigh wave. As in the case of using soda-lime glass, other acoustic wave modes such as Laiib wave and transverse wave can also be transmitted in the glass substrate of the present invention, so that the uncut Si-0- / 0 ~ In glass where the number of Si bonds becomes a very small component, a decrease in the attenuation of some types of sound waves can be observed. The reason is that this general pattern has nothing to do with the acoustic mode. Rayleigh wave energy becomes a form of stress, distortion and lotus motion in both the horizontal and vertical directions. In addition, Rayleigh wave accepts the attenuation mechanism of stupidity with these forms of energy. The shear wave only has energy in the form of shear distortion, stress and lotus motion. In addition, the attenuation mechanism in the shear wave becomes a part of the Rayleigh wave attenuation mechanism. In addition to the buckling wave, which contains only shearing energy, the Lamb wave has energy in both the horizontal and vertical forms. In addition, the ratio is different and it shares the same reduction mechanism as the Rayleigh wave. Because the attenuation mechanism is shared, the glass of the present invention can reduce attenuation for all acoustic wave modes when compared with soda-lime glass. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) [Invention Modes] In the present invention, the sound wave (ultrasonic wave) transmission medium is made of a specific glass substrate Base structure. The touch panel panel composed of the above glass substrate is very useful for checking the coordinate data of the touch position. The glass substrate of the present invention, which is a transmission medium for wave waves, contains Si02 as a main component and an additional component, and the attenuation ratio is about 0.25dB / cn. -20- This paper size applies the Chinese National Standard (CNS) Λ4 specification (210X 297漦) 512274 A7 B7 · V. Description of the invention (0) (for example, about 0.1 ~ 0.23dB / cm), preferably below 0.22dB / cra (for example, about 0.1 ~ 0.21dB / ca). The first special feature of the glass substrate for a touch panel of the present invention is that the total content of Na20, CaO, and MgO (hereinafter collectively referred to as the first component) of the glass with Si02 as the main component and the additional components is low. .

The content of SiO2 is the residual amount of the above-mentioned additional components, for example, about 45 to 90% by weight, and preferably about 50 to 85% by weight (for example, 55 to 85% by weight). Printed by the Employees ’Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (read the precautions on the back and then fill out this page) As the content of the first component increases, on the one hand, the attenuation ratio of sound waves (ultrasonic waves, etc.) increases On the other hand, the strength of the received signal is reduced. The reason can be presumed that the Si-O-Si shared bond in the Sio2 shared bond mesh of the first component contained in the glass is cut off, and the cut-off bond has not replaced the shared bond, strong ion bond, or three-dimensional Formula-restricted ion-binding replacement. In addition, the total content of the first component is kept low. When compared with the soda-lime glass of common glass, it is better to use a glass substrate with a lower total content of the first component. That is, the total content of the first component can be selected within the range shown by the attenuation factor described above, for example, 1 to 20% by weight, preferably 7 to 20% by weight, and most preferably 10 to 20% by weight. % (For example, 11 to 20% by weight). When used to avoid being cut off and inadequately restricted, the content of the Si-0-Si common combination increases, and lower ultrasonic attenuation can be obtained. The increase in attenuation and the decrease in received signal strength can be prevented by using A 1 2 0 3 * Z r 0 2 * T i 0 2 > B 2 0 3 »Y 2 0 3 > S η 0 2 >

Description of the invention ( %) The glass substrate with a higher total content is used for prevention. When compared with soda-lime glass, there is a higher total content of the second component, that is, the total content of the second component is 5% by weight or more, for example, preferably 5 to 30% by weight (about 5 to 20% of directors). The preferred glass substrate is a total of about 7 to 30% by weight of the second component (for example, 7 to 20% by weight), preferably 10 to 30%, and most preferably about 15 to 30% by weight.

Therefore, the glass substrate used to form the touch panel is best selected in the visible light region (wavelength of about 400 ~ 700ηι > having light transmittance. From From a viewpoint of preventing noise, a glass substrate having a high light transmittance in a visible light region preferably has a stronger signal strength than a soda-lime glass. A glass substrate having a high transmittance has Si02 as a main component, and can also be It is composed of glass containing 1st component and 2nd component or other glass (for example, non-gaseous glass). In applications where optical type is required, the sonic touch panel is optically combined with the display device. It is used to exclude the reflection loss and transmission loss caused by the back of the touchpad and the front of the display. To avoid the scattered reflection from the wave-shaped touchpad, you can use silicon dioxide or chemical etching unevenness. Non-glare treatment such as coating (anti-glare treatment) In addition, if there is no problem with fingerprints, reflection can be applied to prevent coating. In both cases, when compared with the wavelength of sound waves, surface treatment Only on the polar surface, the glass substrate will still determine or dominate the relative scientific properties of the control board. -23- (Read the precautions on the back before filling in this page)

Description of the invention (> 4) Loss. The physical effect, that is, the attenuation of the wave energy caused by the substrate, is an important factor in determining the signal amplitude of the wave wave touch panel. In the touch panel of the present invention, the use of the selected glass substrate can be used to reduce the attenuation of the ultrasonic wave, thereby ensuring that the detection of the received signal with sufficient strength can be performed. As a result, the touch position can be detected with high reliability and accuracy. As described above, in the method of measuring the attenuation of the chirped wave by installing the piezoelectric transmitting converter and the receiving converter at different distances, the borosilicate glass (trade name "Dianback period" manufactured by Suntech Glass Co., Ltd.) The average attenuation rate is 0.74 (1B / inch (about 0.3dB / cm), and the average attenuation rate of pin lime glass is K44 d B / B inches (0.57 d B / cm). 0 On the other hand, In the glass substrate of the present invention, the average attenuation rate of the above-mentioned brand name "B270" manufactured by Suntech Corporation is 0.56 to 0.61 dB / inch (0.22 to (K24dB / cin)), a trade name manufactured by Asahi Glass Co., Ltd. "PD-200" has an average attenuation rate of 0.53dB / hour (0.21dB / cin). Therefore, when using the glass substrate of the present invention, the average attenuation rate can be reduced by about 60 when compared with soda-lime glass. ~ 70%, compared with borosilicate glass, the average attenuation rate can be reduced by about 20 ~ 40%.

When compared with borosilicate glass, the above data of "B-2 7 0" and "PD 2 0 0" When the maximum path length of the wave travel is 20 to 40, it indicates an additional signal of about 3 to UB. In the case of a touchpad that is larger than the current commercial products, it can make the signal profit become Larger. -2 6-This paper size applies the Chinese National Standard (CNS) Λ4 gauge (210X 297 cm) 512274 A7 V. Description of the invention (4) Acoustic wave attenuation is a multiplication function of the number of vibrations. The calculation is performed at a test frequency of 5.53 MHz. If the product is designed to have a higher operating frequency, the chirp attenuation becomes larger, so the glass with less chirp loss is used to increase the gain. If the product is made larger, It is reversed when designed to a lower frequency. The number of quantities varies but the advantages of low sound wave loss glass substrate quality remain unchanged. 5. 53MHz sound wave attenuation test can determine a wide range (such as 3 ~ 10 M) Hz range Low sound wave loss glass substrates used in products with operating frequency range. That is, "low sound wave loss glass" can be defined as follows: Install a pair of 0.5-inch wide wedge-shaped converters on the test object glass, according to the signal The loss of the 5.53MHz Rayleigh wave's chirp loss measured from the slant of the account to the tilt of the drawing is below G. 25dB / cni. From the glass using the touch panel combined with the glass of the present invention The data indicates a significant increase in signal amplitude, which proves that the glass substrate of the present invention can provide the same scientific advantages.

Depending on the application, it is best to use reinforced glass substrates. Borosilicate glass cannot be thermally strengthened because it has a low number of thermally expanded particles. Because the sodium ion that can be replaced with potassium ion has a low content rate or does not contain sodium ion, the ordinary borosilicate glass can only be hardened by a very limited chemical formula. In applications where a strengthened glass substrate is required, it is preferable to use a strengthened low-wave loss glass. By selecting the above-mentioned specific glass as the substrate material for the acoustic wave contact plate, it was found to be feasible. The glass of the above-mentioned examples such as "B 270" manufactured by Chante Glass Co., Ltd. is an example of a low-wave loss glass that is easily formed into a sheet shape, can be purchased economically, and can be optionally thermally strengthened or chemically hardened.

Description of the invention () The additional signal amplitude obtained with this glass substrate can be improved SN bb has a variety of products with significant loss, and several examples of improvement of these products will be explained below. When designing converters (such as components 3a, 3b, 6a, and 6b), the designer ’s A compromise must be achieved between the mechanical fit of the touchpad. According to the situation, the designer can avoid the interference of the machine map by reducing the width of the converter from 0.5 inches to 0.25. The degree is reduced Converter, because the opening of the angle of the chirped beam from the narrower converter is increased, so it is the cause of signal loss. In other cases, the designer can make the edge of the appropriate glass substrate equipped with a wedge-shaped converter. Including inclined surface. If the inclination angle is very sharp, wedge-shaped converter can be well installed under the touch surface when the wedge angle is 33 ° or more. However, the touch surface and this sharp tilt The crossover of the surface is the cause of the non-connected minerality of the wave, which will cause significant signal loss.

The glass substrate is usually thermally strengthened. This glass can be easily purchased. When using this glass, it can make The size of the acoustic wave control board becomes larger. The thermal expansion pseudo number of the heat-strengthable glass is usually about 6X l (Te / K or more, preferably about 6X ΙΟ · 6 / K ~ about KIX 10 $ / Κ, better is about 7Xl0-6 / K ~ about 10 × ΐ〇 · β / Κ, the best is about 8 × UT6 / K ~ about 10 × IO · 6 / κ ❶ This kind of glass can strengthen it The fact can be explained as the result of the thermal expansion of the glass. The above-mentioned "B 2 7 0 j technical data circle table records the thermal expansion coefficient of 9 · 5 × ΙΟ # / K (20 ° C ~ 30fleC)," PD 200 " The thermal expansion coefficient is about 8 · 3 × 1 (Τ6 / K. This value is the value of soda lime glass It is similar, but it is very different from borosilicate glass with a thermal expansion pseudo number of 3.25 × l (Te / K, "Boloflot J, etc." In the use of a strengthened glass substrate, a hardening treatment must be used to make the reflective array. Materials and glass do not anneal. For example, polymer-based, low temperature hardening reflective materials can be used. When compared with the glass material of the conventional reflective material, because the polymer material rapidly attenuates the wave power, the importance of the low wave loss substrate is increased. As a reflective array material, you can use the reflective ink β with a hardening temperature lower than the glass frit, and the glass annealing temperature β. The ELS "4fl22C" frit with a thermal expansion ratio of 8 · 8 × 1 〇-β / Κ is typical of October and 蚺 lime glass. The thermal expansion coefficient matches the value, so it is widely used.

The glass substrate can also use safety glass composed of multiple glass layers. In this case, the inner and outer layers of the sacral body usually have approximately or substantially the same number of thermally expanded films. For example, a laminated body of two glass plies having an inner layer and an outer layer is used to form a glass substrate. The glass with the above characteristics can make the outer layer have an attenuation image number of 0.25 dB / c · or less. In addition, it is also possible to use a part of the structure of the safety glass, that is, a laminated body using a glass sheet of 2 mm (the inner glass 151 and the outer glass 152 with a touch surface 152a are laminated to form a laminated body through a bonding agent 153). To form a large control board (refer to the seventh garden). In safety glass (laminated glass), one or both of the glass can be thermally strengthened or chemically strengthened (hardened). For example, the Rayleigh wave type: 5 · 5 3 Μ ζ ζ is used to operate: the substrate for the control board becomes a strengthened glass layer with a low wave loss (thickness, the glass layer can also be laminated at the first 2 Strengthen the low-wave loss glass layer (thickness 3 βικ). That is, in the safety glass stack, the outer layer (the layer with the touch surface formed) is limited to the glass with a low attenuation number, and the inner and outer layers can be both In order to strengthen the glass, the outer layer can also be made of glass with a thermal expansion coefficient of 6 × 1 (Τ6 / κ or more.) When the load or impact is applied to the safety glass substrate, even the lower glass layer can be strengthened. Adds significant strength. When the safety glass substrate is subjected to a load, it bends, the upper glass layer is compressed, and the lower glass layer is stretched. The glass is stronger in the compressed state than in the stretched state. The stretched glass layer Strengthening is extremely important. The prototype control panel using unstrengthened laminated glass will be due to the upper control surface -32- This paper size applies to China National Standard (CNS) Α4 specification (210 X 297 public power) ( Notes on the back read and then fill this page)

Description of the invention (W) (Please read the precautions on the back before filling this page). Crack the bottom glass. However, when the cracks on the bottom glass can be clearly seen, the upper glass layer will not break, and it has the function of a prototype touchpad. It has been experimentally proven that the lower glass is properly strengthened to become an important layer. Therefore, in the safety glass, the inner layer is made of tempered glass very effectively, and tempered soda glass with a large attenuation range can be used. When a lower-layer strengthened soda-lime glass (for example, a thickness of 3bB or more) and an unreinforced shed silicate glass (for example, a thickness of 3m ·) coupled to the lower layer are used to form a safety glass substrate, the actual It cannot be used for a wide operating temperature range. The thermal expansion coefficients of borosilicate glass and soda lime gray glass are very different. Due to the temperature change, the substrate will bend like a thermostat's double gold substrate. The effect of bending was observed experimentally. Bond the borosilicate glass sample to the unreinforced soda lime glass sample. The size of the two samples was 6:00 X 9:00. The laminate was placed in 觼. The temperature was changed by 30 ° C. As a result, it was clear that the small laminated sample was bent. It is 31, but the thickness is so low that the glass layer that is laminated in the body is not as strong as the glass loss. The glass wave gray ocher is low in sodium. It is strong and compatible.

Description of the invention (>) There is still another advantage. The bonding force between the ordinary glass frit and the borosilicate glass substrate used as the reflective array material is currently lower than the bonding force between the glass frit and the soda-lime glass substrate. This is due to the mismatch in thermal expansion coefficients between the frit and the borosilicate glass. It can be improved when there are glass frit components which are more suitable for the thermal expansion coefficient of borosilicate glass. However, the hardening temperature will be higher than 5 ° C. When compared with boron laurate glass, the low-wave loss glass of the present invention has the advantage that its thermal expansion image is suitable for the standard frit products with low sintering temperature. The glass substrate of the invention is suitable for transmitting various sound waves, and is not limited to Rayleigh waves.

Description of invention (W) When the operating frequency is 5.53MHz, the wave dynamics of the Rayleigh-transverse-Rayleigh-velvet tester limits the thickness of the glass to approximately 3 *. In addition, the Rayleigh-transverse-Rayleigh tester Because both the top and bottom sides of the glass have touch resistance, they cannot be laminated as part of the safety glass using standard safety glass adhesives (requires the use of a silicone rubber with almost no viscosity attenuation). The tincture is due to the wave dynamics requirements of Rayleigh-transverse-Rayleigh-touchpad, so the reinforced low-wavelet loss glass of the present invention is particularly suitable for large Rayleigh-transverse-Rayleigh-touchpad. Effect] Employee Consumer Cooperatives, Central Standards Bureau, Ministry of Economic Affairs (Please read the precautions on the back before filling this page) In the acoustic wave touch panel of the present invention, the acoustic wave attenuation of the glass substrate can be reduced, and the transmitted signal can be guaranteed to have high strength. Therefore, for electromagnetic interference, it can improve Reliable and high-durability chirped wave control boards and low-cost control devices allow operation with high reliability even when transmitting burst amplitudes with peak-to-peak voltages below about 10 volts. Use a mechanically small converter with low signal conversion efficiency. In addition, it is also possible to use a seal that generates a sound signal, which can increase the size of the control board. In addition, when it is used as a laminated glass, the operation of making rough and rough can also have reliability and make the touch surface firm.

However, this measurement is very useful for comparison with other glasses (because the reflection on the front and back of the glass is 4%, so 92% transmission is theoretical The upper limit of reflection. The reflection is caused by the inappropriate refractive index of air and glass. The refractive index of glass is typically η = 1 · 5, so the reflection on one side (n-1 / n + l) 2 is about 4 %). In addition, the result of measuring the attenuation coefficient by the above method is 0.57dB / c «u. The transmission speed of the chirp wave is measured according to the following method. The transmission speed of the acoustic wave is obtained by changing the distance between the elements of the reflection array or The interval is to be observed when the vibration of the received signal is the maximum.

The distance between the widths is used to determine the wavelength, and the product of the wavelength and frequency (5.53MHz) is used to calculate the speed. Similar to the condition of Rayleigh wave touchpad products on the market, the acoustic signal is sent to the glass with a wedge-shaped converter. The wedge-shaped converter is composed of a ceramic piezoelectric element bonded to a plastic wedge, and the wedge is bonded to a glass surface. This wedge shaped the Rayleigh wave-to-signal converter that coupled the acoustic mode pressure wave from the piezoelectric element on the glass substrate with a 5.53MHz tone cluster with a 50V amplitude. The conveying speed of the soda-lime glass substrate was measured in this way, and the result was 125 500 hours / second.
