Abstract
The present invention relates to a film touch sensor in which a separation layer is formed on a carrier substrate prior to the formation procedures of the touch sensor, and a method of preparing the film touch sensor. The film touch sensor according to the present invention comprises a separation layer; an electrode pattern layer formed on the separation layer and comprising a sensing electrode and a pad electrode formed at one end of the sensing electrode; and an insulation layer formed on the electrode pattern layer and used as a base film layer.
Claims35
A film touch sensor, comprising:
- a separation layer;
- an electrode pattern layer formed on the separation layer and comprising a sensing electrode and a pad electrode formed at one end of the sensing electrode;
- an insulation layer formed on the electrode pattern layer and used as a base film layer;
- and
- a pad pattern layer formed on a bottom of the pad electrode:
- wherein the separation layer is formed on a carrier substrate and then separated therefrom.
A method for preparing a film touch sensor, comprising the steps of:
- forming a separation layer on a carrier substrate;
- pre-forming a pad pattern layer in a region to form a pad electrode prior to the formation of the pad electrode;
- forming an electrode pattern layer comprising a sensing electrode and the pad electrode on the separation layer;
- forming an insulation layer to be used as a base film layer on the electrode pattern layer;
- and
- removing the carrier substrate by separating the separation layer from the carrier substrate.
