Description of the Invention (1) [Technical Field] The present invention relates to a touch panel and a method for using it to input coordinate information of a touch position. [Background Art] A touch panel is combined with a display device such as a cathode ray tube (c R T), a liquid crystal display (L C D), and is used as an input device in various fields. For example, in Japanese Patent Laid-Open No. 1 1-6 5 7 6 5, a glass substrate 1 b used for transmitting acoustic waves (surface acoustic waves) is disclosed, and the glass substrate 1 b is mounted on the surface of the glass substrate 1 b and faces the X-axis direction of the substrate. And a set of transmitting converters 2a and 2b for transmitting clinoid waves in the γ-axis direction, and receiving converters 3 a and 3 b for receiving acoustic waves from the transmitting converters 2a and 2b to detect touch positions Acoustic wave type touch panel (see Figure 2). In addition, it is described that safety glass (laminated glass) in which the inner glass plate and the outer glass plate can be laminated using the glass substrate 1b via an adhesive. In this acoustic wave type touch panel, because it is used in combination with a display device, it is necessary to cut the glass substrate in accordance with the shape of the display portion of the display device. Therefore, generally, a groove is formed on the surface of the glass substrate using a diamond tool (a diamond cutter, etc.), and the glass substrate is bent and cut along the groove. However, in the glass cut surface 4b, the plurality of thin curved surface type flat portions are irregularly undulated and joined in the substrate thickness direction and the entire length direction. In addition, this cutting surface and the edge portion 5 of the glass substrate surface are at an acute angle, becoming sharp — II ------ — — — — — — ------ order --- II ----- (Please read the precautions on the back before filling out this page) This paper size applies Chinese National Standard (CNS) A4 (210 X 297 mm) -4-Printed by the Intellectual Property Bureau Staff Consumer Cooperatives of the Ministry of Economy 523705 A7 _ B7 5 2. Description of the invention (2) Knife-shaped. Therefore, it is easy to injure a finger by the edge part 5, and it is easy to cause unnecessary reflection of a surface elastic wave, and it becomes a cause of an inconvenience. At this time, as shown in FIG. 3, although the honing edge portion 5 can be used to form a smooth chamfered surface 6 (cornering treatment), the glass frit (sheet) generated by the chamfering treatment hurts the glass substrate 1 c. The surface (upper surface) may reduce the transparency of the glass or the transmission of acoustic waves. In addition, with the cutting method of the diamond tool described above, safety glass (laminated glass) cannot be cut. According to Japanese Patent Laid-Open Publication No. 11-1; L 9 i 3 4 1, it is disclosed that a hard coating (heat-curing or light-curing resin), a flexible transparent film (engineering plastic film, etc.) The upper electrode plate formed of the upper electrode and the lower electrode plate formed of the glass substrate and the lower electrode are formed through the spacer to form a touch-sensitive panel of a resistive film method facing the stack. In this document, as an example of the manufacturing method of the touch panel described above, the upper electrode is divided into a plurality (for example, 4) of the upper electrode plate and the lower electrode is divided into a plurality (for example, 4) (A) A method in which the lower electrode of the electrode portion is laminated through a spacer, and this laminated plate is cut into individual electrode portions using laser light cutting. Therefore, it is an object of the present invention to provide a touch panel with superior safety (low abrasion resistance) and a method of using the touch input surface even if the touch input surface is made of a glass substrate without applying a chamfering process. Another object of the present invention is to provide a touch panel and a method for using the same, although the glass substrate is cut in accordance with the shape of the display device, but the surface of the glass substrate is less damaged.

Description of the invention (3) [Disclosure of the invention] The inventors and others worked hard to achieve the above problems As a result of the review, when the touch-sensitive panel that cuts the acoustic wave method using a laser beam type water jet, etc., the cut surface can be smoothed. Therefore, although the glass substrate is used for the touch input surface, safety is found. The dehorning treatment used to prevent the reflection of the surface elastic plate that is not required is unnecessary and can be omitted, and the present invention is finally completed. That is, in the touch panel of the present invention, the touch input surface is formed by a glass substrate whose outer peripheral portion is cut, and the edge portion of the cut portion of the glass substrate is smooth. The outer periphery of this glass substrate is usually cut with a water jet laser beam. The glass substrate may be laminated glass. This touch panel can detect the touch position by acoustic waves. The present invention also includes a method of using the touch panel as an input device of a display device. [Best Mode for Carrying Out the Invention] The touch panel of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic perspective view showing an example of a touch panel of the present invention. This touch panel is a touch panel of the surface acoustic wave (acoustic wave) method. In order to send the surface elastic wave to the glass substrate 1 a surface (touch input surface) 7 for transmission conversion Transmitter (transmitting device) (in this example, a transmitting converter 2a that sends a surface elastic wave in the X-axis direction, and a transmitting converter 2b that sends a surface elastic wave in the Y-axis direction), and will receive from these transmitting converters 2 The surface elastic waves of a and 2 b are reflected to the receiving converters 3a and 3b. On the surface 7 of the glass substrate la, a Chinese national standard (CNS) A4 specification (210 X 297 mm) applicable to this paper size is formed. -6-- --- — — — — — — — — — — ———— Order --If — — — II (Please read the notes on the back before filling this page) 523705 A7 B7 V. Description of the invention (4 ) Reflective array group with both ends in the Y-axis direction extending in the X-axis direction 8 a, (Please read the precautions on the back before filling in this page) 8 b, with both ends in the X-axis direction extending in the Y-axis direction The reflection array group 8 c, 8 d. The touch position can be detected in the area surrounded by these reflection array groups 8a ~ 8d. That is, the surface acoustic wave transmitted from the transmitting converter 2a in the X-axis direction is reflected by the reflection array group 8a in the -Y-axis direction. The surface acoustic wave reflected in the -Y-axis direction is reflected by the reflection array group 8 b in an X direction, and is received by the receiving converter 3 a. When any point (for example, point P) on the surface 7 of the glass substrate is touched, the surface elastic wave is disturbed. Therefore, by measuring the time t when the disturbed surface elastic wave reaches the receiving converter, the touch position (X coordinate) can be measured. Similarly, in the Y-axis direction, the surface elastic waves transmitted from the transmitting converter 2 b are reflected by the reflection arrays 8 c and 8 d and detected by the receiving converter 2 b to detect the Y coordinate of the touch position. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In the touch panel, the outer part (side part) 4 a of the glass substrate 1 a is cut by a water jet. That is, the cutting by the water jet flow is from a nozzle located in the approximate normal direction of the glass substrate 1 a toward the above-mentioned glass substrate 1 a and will contain ultra-high pressure water (1x108 ~ l) of a honing material (garnet). 〇xl08Pa, preferably about 3x 1 08 ~ 7x 1 08P a) is sprayed approximately perpendicularly, so that the mechanical external force (friction) of the high-pressure water (or honing material) is cut off while honing the glass substrate. Therefore, unlike cutting a glass substrate with a diamond tool, the cutting surface 4a using a water jet is a direction in which high-pressure water is ejected, that is, a smooth portion extending in the thickness direction of the substrate is formed, and the entire cut surface becomes smooth. In addition, cutting by water jet is different from cutting by bending with a diamond tool. 'China National Standard (CNS) A4 specification (210 X 297 mm) applies to this paper size. Printed by the Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs 523705 A7 B7 V. Description of the invention (5) The edge portion can be honed by cutting. Therefore, the edge portion 5 of the section 4a and the glass substrate surface 7 does not form a sharp portion, and is smooth and safe. In addition, the glass piece (powder) that has been cut off by the water jet is washed away with water or honing material, so as not to damage the surface 7 of the glass substrate. In addition, damage to the surface of the substrate can prevent the transmission of the surface elastic wave from being hindered (scattered reflection), so that the detection accuracy of the surface elastic wave (that is, the detection accuracy of the touch position) can be prevented from decreasing. The hole diameter of the high-pressure water jet (nozzle) when the water flow is cut off is, for example, about 1 to 2 mm, preferably about 1 to 10 mm. As a glass substrate, a variety of glasses can be used depending on the position detection method. To use elastic waves, for example, soda glass, borosilicate glass, lead-free glass (cr ◦ wng 1 ass), barium-containing glass, and thorium-containing glass can be used. Boron-containing glass, the glass disclosed in Japanese Patent Laid-Open No. 1 1 6 5 7 6 7 (using a Lily wave of 5 · 5 Μ Η z (the attenuation coefficient when Lily wave is 0 · 5dB / cm or less) Glass) etc. In addition, in the present invention, since no chamfering treatment is necessary, the smoothness of the surface of the glass substrate is not impaired. Therefore, it can be effectively used for glass substrates with better surface smoothness, such as floating glass, etc. The glass substrate can also be made of tempered glass or laminated glass. For example, laminated glass is made of front glass and back glass through an adhesive (thermoplastic resin, such as poly vinyl acetal resin). It can be formed by cutting. Unlike cutting by bending with a diamond tool, water jet cutting (or laser light cutting described below) can be cut even if it is bonded to glass, which can be applied to this paper size.

Description of the invention (6) Simple change of the size of the touch panel with display device. Glass substrate The thickness is, for example, about 1 to 10 mm, preferably about 2 to 8 mm, and even more preferably about 3 to 6 mm. Especially when used in combination with a large-sized display device, from the viewpoint of the strength of the touch panel Thick glass with a thickness of about 3 to 10 mm is preferred. The glass substrate is not limited to a special shape, but may be a flat shape or a curved shape. Moreover, the glass substrate can be smoothed as long as it can be cut. When cutting the glass, you can also use a method other than the water jet cutting method. For example, you can also cut the glass while melting (laser light cutting, etc.). For cutting using laser light (carbonate laser) Laser, YAG laser, etc.), the glass is cut (or sublimated) by laser light. Therefore, when the laser light is irradiated to the thickness direction of the glass substrate, a smooth cut surface is formed in the thickness direction of the substrate in the same manner as the water jet cutting. In addition, the edge portion can be chamfered from the melted by the laser irradiation. The touch panel of the present invention is not limited to the touch panel of the above-mentioned acoustic wave method, but includes a touch panel of which the touch input surface is a glass substrate. In the present invention, the glass substrate is It can be cut by water jet cutting or laser light cutting, etc. It is not necessary to apply chamfering, and it is easy to obtain a touch panel with high security. When the touch input surface is a touch panel composed of a glass substrate 'Contains: an optical touch panel consisting of a glass substrate touched by a finger or a pen, and a light transceiving device used to scan and detect the touch position with light (infrared beam, etc.) on the surface of the glass substrate (see Japan Patent kaiping -------------------- Order —------- line— (Please read the precautions on the back before filling this page) This paper size Applicable to China National Standard (CNS) A4 (210 X 297 (%) -9-523705 Printed by A7 B7, Consumer Cooperative of Employees of Intellectual Property Bureau of the Ministry of Economic Affairs 5.

The input position can be used in combination with display devices such as cathode ray tube (CRT), liquid crystal display (LCD), plasma display and so on. The surface is made of a glass substrate. Since the glass substrate is cut by water jet cutting or laser light cutting, the cut surface is smooth, which is superior to safety. In addition, the reflection of unwanted surface acoustic waves is reduced, so that no undesirable situation occurs. In addition, since the cut surface does not need to be chamfered, damage to the surface of the glass substrate can be reduced. In addition, when used in combination with a display device, the size of the display portion of the display device can be easily changed.
