Title: FILM FOR TOUCH SENSOR, TOUCH SENSOR ASSEMBLY COMPRISING SAME, AND METHOD FOR PRODUCING A TOUCH SENSOR ASSEMBLY
Abstract:
The invention relates to a touch sensor assembly having a sensor mounted on a three-dimensional surface thereof, and to a method for producing the touch sensor assembly. For this purpose, the touch sensor assembly according to one embodiment of the present invention comprises: a base member having a three-dimensional surface; and a film for a touch sensor, which has a transparent conductive layer made of carbon nanotubes to sense a variation in capacitance due to contact from an external source, and which is formed integrally with the three-dimensional surface of the base member. Consequently, electrical characteristics such as a sheet resistance of the film for a touch sensor scarcely changes, and thus causes no thermal deformation in the film for a touch sensor even when the film for a touch sensor is warped by pressure and heat during the process in which the film for a touch sensor is formed integrally with the three-dimensional surface of the base member. Further, the touch sensor of the present invention can be transformed into a specific shape in accordance with the design of a manufacturer without causing cracks on the transparent conductive layer.
