Abstract

An in-mold molding touch module includes a plastic film, a touch circuit and a molding rind. The plastic film includes an inner surface and an outer surface for handling and touching. At least one region of the inner surface and a corresponding region of the outer surface define a touch area. The touch circuit is arranged on the inner surface in the touch area. The molding rind is integrated on the inner surface by an in-mold injecting mode to contain the touch circuit for forming a one-piece body. In addition, the invention also provides a method for manufacturing an in-mold molding touch module.

Claims (10)

1. An in-mold molding touch module comprising:

a plastic film having an inner surface and an outer surface for handling and touching, and at least one region of the inner surface and a corresponding region of the outer surface defining a touch area;

at least a touch circuit integrated on the inner surface in the touch area;

and a molding rind molded on the inner surface being an in-mold injected contain the touch circuit to form a one-piece body.

2. The in-mould molding touch module of claim 1 , wherein the touch circuit is an inducing capacitive touch circuit made of indium tin oxide (ITO) or a press touch circuit made of conductive printing ink.

3. The in-mould molding touch module of claim 1 , wherein the touch area comprises a first touch region and a second touch region, and the touch circuit comprises:

an inducing capacitive touch circuit made of ITO, the inducing capacitive touch circuit coated on the inner surface in the first touch region; and

a press touch circuit made of conductive printing ink, the press touch circuit coated on the inner surface in the second touch sense region.

4. The in-mould molding touch module of claim 3 , wherein a window is formed in the molding rind to expose the inducing capacitive touch circuit, and a display unit is configured in the window for display images through the inducing capacitive touch circuit and a transparent region of the plastic film.

5. The in-mould molding touch module of claim 3 , wherein the molding rind further contains the capacitive touch sense circuit for forming the one-piece body.
