  • Touch panel sensor 10 contains a transparent flexible substrate 1 , a transparent conductive film 2 formed on the transparent flexible substrate, wiring 3 composed of a metal or metal alloy, and electrodes 4 composed of a conductive ink or paste for connecting the transparent conductive film 2 and the wiring 3.
  • Touch panel sensor 10 is designed to detect a contacted location when the finger of a user or a conductive bar or other measuring object has contacted transparent conductive film 2 in active region A of touch panel sensor 10. Touch panel sensor 10 supplies a signal that indicates the contacted location (X 5 Y) in specific X-Y coordinates. This signal is sent to a suitable controller (not shown) for converting analog data to digital data that is connected to the ends of the wiring through wiring 3.
  • Touch panel sensor 10 contains a transparent flexible substrate 1.
  • transparent refers to being optically transmittable to a degree to which, when the touch panel sensor is arranged on a device below it (normally, a display device), that device is visible. Thus, this is also intended to refer to a "translucent" material as well. As shown in
  • substrate 1 is typically in the shape of a rectangle, and has a tail section 5 extending from the end on one side.
  • substrate 1 may be in the shape of, for example, a circle, square, triangle or polygon.
  • Substrate 1 should be a known transparent insulating film, examples of which include polyesters such as polyethylene terephthalate (PET) and polyethylene naphthalate (PEN) and polycarbonates. From the viewpoints of cost and transparency, it is preferably composed of polyethylene terephthalate (PET).
  • PET polyethylene terephthalate
  • other materials can also be used such as polyvinyl chloride, polyether sulfone, polyimide polyether imide and cellulose triacetate.
  • the thickness of substrate 1 is preferably 10 to 3000 ⁇ m. If the thickness is less than 10 ⁇ m, handling ease becomes poor, while if the thickness exceeds 3000 ⁇ m, flexibility becomes low, making it difficult to install in a display device. In addition, bar coat processing or reflection preventive treatment may be performed on transparent flexible substrate 1.
  • a transparent conductive film 2 is formed in region A on transparent flexible substrate 1.
  • Conductive film 2 may be formed over the entire active region A, or a plurality of band-like conductive films 2 may be formed in parallel as shown in Fig. 1.

  • ITO indium tin oxide
  • other materials that can be used include indium oxide, silicon indium oxide, aluminum zinc oxide, indium zinc oxide, antimony tin oxide and tin oxide.
  • sheet resistance value is normally 300 to 5000 ⁇ /square. If this resistance value is too low, it becomes difficult to increase resolution, while if this resistance value is too high, it becomes difficult to form a conductive film.
  • the thickness of conductive film 2 is preferably as thin as possible in order to avoid excessive stress and improve optical transmittance when touch panel sensor 10 has been bent. On the other hand, the thickness of conductive film 2 must not be so thin so as to impair film continuity or its material characteristics. Consequently, the thickness of conductive film 2 is normally 0.01 to 0.1 ⁇ m. Conductive film 2 can typically be formed on substrate 1 by sputtering.
  • Conductive film 2 is connected to wiring 3 via electrodes 4 composed of conductive ink or paste.
  • Wiring 3 is composed of a metal such as copper, nickel, gold, aluminum, silver or tin, or an alloy thereof.
  • the resistance of wiring 3 is preferably as low as possible, and should preferably not cause a disconnection due to the formation of cracks when substrate 1 is bent. Consequently, wiring 3 is preferably formed directly on substrate 1 without using an adhesive, and is composed of only a metal or alloy that is free of binder.
  • Wiring 3 composed of a metal or metal alloy can be formed by plating described in, for example, Japanese Unexamined Patent Publication No. 6-283261. More specifically, after forming a thin undercoating metal layer by sputtering a metal such as copper on flexible substrate 1 , plating is performed on the undercoating metal layer to form wiring 3 of a desired thickness.
  • wiring composed of a metal or metal alloy can be formed by metal foil lamination as described in Japanese Unexamined Patent Publication No. 2004-106336. More specifically, wiring 3 can be formed in the manner described below.

  • a non-alloy conducting layer is formed on the substrate surface scheduled to be joined. The non-alloy conductive layer is formed by sputtering and so forth.
  • This layer can be of the same material as the material used for transparent conductive film 2 in the form of a thin film having a thickness of 0.01 ⁇ m or more.
  • the surfaces of the non- alloy conducting layer and metal foil that are scheduled be joined can be joined by lamination. Furthermore, lamination and joining can be carried out at a temperature of 0 to 15O 0 C.
  • Wiring 3 can be formed by pattern etching a substrate having a metal foil obtained in this manner.
  • Wiring 3 preferably has a thickness of 1 to 100 ⁇ m. If the thickness of wiring 3 is less than 1 ⁇ m, there is the risk of a connection defect caused by wiring 3 being scraped off during connection with a ZIF connector used to connect with a controller or other external device. On the other hand, if the thickness of wiring 3 exceeds 100 ⁇ m, the stress applied to wiring 3 increases when flexible substrate 1 is bent, thereby resulting in a higher possibility of a disconnection. Surface treatments such as oxidation preventive treatment, nickel-gold plating, tin plating may be performed on wiring 3. Wiring 3 is connected to the connector of a controller that controls the touch panel at the end of tail section 5 extending from one side of the substrate.

Measurement of Sheet Resistance
  • Example 1 in contrast to the average sheet resistance in Example 1 being 2.1 k ⁇ /square at a variance of +10% or less, in Comparative Example 1, the sheet resistance varied. This is due to the occurrence of connection defects between the copper wiring and ITO bars. In the case of being unable to obtain uniform sheet resistance of the ITO bars as in Comparative Example 1, the touch panel sensor is unable to demonstrate adequate finger recognition. On the other hand, in the case of being able to obtain uniform sheet resistance of the ITO bars as in Example 1, the touch panel sensor is able to demonstrate adequate finger recognition.
  • the durability of the wiring in the tail section was investigated using a scratch tester (HEIDON Type 18LFW) manufactured by Shinto Scientific. Test Method: Scratching needle material: Sapphire, tip diameter: 0.05 mm, radius of curvature R: 0.05 mm, apex angle: 90°
  • Example 1 After carrying out scratch tests on the touch panel sensors of Example 1 and Comparative Example 2, the degree of damage to the wiring was observed using a light microscope. In Comparative Example 2, the scratch marks reached to the surface of the PET substrate resulting in exposure of the PET surface. In Example 1, on the other hand, although there were scratch marks on the copper wiring, none of the scratches penetrated the copper. Thus, Example 1 was determined to demonstrate higher durability with respect to scratching, and as a result, was concluded to have high durability with respect to the attachment of ZIF type connectors. On the basis of these results, the present invention is a touch panel sensor having high wiring durability in the sensor tail section.
