Definitions

  • the present invention relates to a touch film, in particular, a capacitive type and a reduced pressure (low
  • It relates to a touch film that can operate both of the anti-film) method.
  • the capacitive touch input method has disadvantages that it is impossible to input non-conductive materials and that the possibility of malfunction is higher than that of the pressure-sensitive touch input method when the touch screen is damaged, and the pressure-sensitive touch input method uses almost anything other than fingers and pens. Since you can touch the screen, it has the advantage of being able to input whatever tool you use, but it has the disadvantage that the screen's sharpness is generally poor and it is weak against impact.
  • the present invention has been conceived to solve the problems of the prior art as described above, and an object of the present invention is to provide a capacitive type and a pressure sensitive type touch film capable of operating both a capacitive type and a reduced pressure (resistive film) type.
  • the capacitive and pressure-sensitive touch film maintains the thickness of the dielectric and the conductor material at a specific ratio by combining the dielectric and the conductor material, and thus the capacitive and reduced pressure (resistive film) method. It is characterized in that it is configured to be both operable.
  • a touch film capable of operating not only in water but also in a capacitive type and a reduced pressure (resistive film) type.
  • This new material is that it is possible to make a mobile phone that can be touched with anything by inserting a new material according to an embodiment of the present invention on an existing capacitive device (cell phone, navigator, POS, PDA, etc.).
  • the composition of a new material according to an embodiment of the present invention is made of a single new material through coating, printing, lamination, etc. on a material having a good dielectric constant such as acrylic, silicon, urethane, etc., and a conductive material such as silver nanowire. Therefore, it is meaningful to accurately make the ratio so that the decompression method and the electrostatic method operate simultaneously.
  • the thickness of dielectric materials such as acrylic, silicone, urethane, etc. must be at least 05mm, and there is no problem in operating force when it is coated, printed, or laminated with a conductive material.
  • the best degree for human touch is dielectric It is believed that the best working condition is when the thickness of the material (acrylic, silicone, urethane, etc.) is around 1mm.
  • the dielectric material referred to here refers to a soft material that is not hard and has a certain degree of pushability. It is particularly used for liquid crystals.
  • the main feature of this dielectric material is that it is transparent.
  • the new material according to an embodiment of the present invention which is produced by combining a dielectric material and a conductive object, has to implement both the electrostatic method and the depressurization method at the same time, so it should not be biased in any method, and the ratio of the dielectric material and the conductive object is the biggest challenge.
  • the dielectric In order to meet the 5:5 ratio that enables the electrostatic method and the decompression method to be implemented at the same time, the dielectric must have a certain thickness, and this thickness is at least 05mm, which is operated above this minimum thickness. This thickness is in the case of Apple's in-type touch screen, and in the case of on-type touch screens such as Samsung, it can operate even under 05mm.
