Title: TOUCH SENSOR
Abstract:
The present invention relates to a touch sensor comprising: a plurality of touch circuit units formed by printing conductive ink on a Polyethylene Terephthalate (PET) film; a PET terminal unit inserted into a connector for connection with an external integrated circuit (IC), wherein the PET terminal unit is formed by forming a plurality of signal lines respectively connected to the plurality of touch circuit units by printing conductive ink on the PET film and by concentrating the plurality of signal lines on one end portion of the PET film; a protective coating layer formed on the PET film on which the plurality of touch circuit units and the PET terminal unit are formed; and a terminal-reinforcing plate bonded onto the PET terminal unit by using a predetermined adhesive, wherein the terminal-reinforcing plate is thicker than the PET film and is formed of hard synthetic resin. Accordingly, the touch sensor is simplified. Therefore, the volume and weight of the touch sensor are minimized, attachment to a target is easy, and detachment during the use of the touch sensor can be prevented. Further, due to the terminal-reinforcing plate bonded onto the PET terminal unit, the problem of difficulty in securing an electrical connection with the outside, which is caused by the PET film used as a material of the touch sensor, can be solved.
