  • Patent number: 7830366
    Abstract: The touch panel of the present invention has a thermally color-changing portion in the vicinity of a connecting portion which is to be bonded by heat. It can be easily checked whether the heat press has been performed at a predetermined temperature when the wiring board is connected to the top and bottom substrates, based on the degree of coloring of the thermally color-changing portion. This allows the touch panel to be manufactured simply and to ensure reliable electrical contact and separation.

  • Patent number: 7820294
    Abstract: A touch panel includes a light-transmittable upper substrate, a light-transmittable upper resistor layer on a lower surface of the upper substrate, a light-transmittable lower substrate, a light-transmittable lower resistor layer on an upper surface of the lower substrate, an adhesive layer on an upper surface of the upper substrate, and a light-transmittable plate on the adhesive layer. The upper substrate is made of material having oxygen and nitrogen removed therefrom. The lower resistor layer faces the upper resistor layer by a distance. The light-transmittable plate disables oxygen and nitrogen to pass through the plate substantively. Even being used in high temperatures, this touch panel does not produce an air bubble in the adhesive layer, hence allowing a user to clearly view a display device through the touch panel.

  • Patent number: 7297887
    Abstract: A touch panel which is constituted by using an adhesive layer having a thickness which is 70% or more of a thickness of an approximately picture-frame-like spacer which allows respective outer peripheries of an upper substrate and a lower substrate to adhere to each other is provided. Due to such a constitution, when the touch panel is used under high temperature or in an environment where the temperature difference is severely large so that the thermal expansion or shrinkage is generated on upper substrate or lower substrate, these thermal expansion and shrinkage can be absorbed by the thick and soft adhesive layer. As a result, it is possible to suppress the peeling-off of upper and lower substrates thus realizing a surely manipulable touch panel.

  • Patent number: 7268311
    Abstract: A touch panel includes a first substrate, a second substrate, a polarizing plate and a compensating plate. A first conductive layer is formed on the first substrate. The second substrate is formed so as to face the first substrate and has a second conductive layer facing the first conductive layer at a certain interval. The polarizing plate having a heat shrinkage ratio larger than that of the first substrate is laminated on a side, which is opposite to the second substrate, at the first substrate. The compensating plate having substantially an identical heat shrinkage ratio with that of the first substrate is laminated on a side, which is opposite to the first substrate, at the polarizing plate.
