Module molding touch module
View Patent ↗An in-mould molding touch module includes a flexible printed circuit having a touch control circuit, and a molding flexible film. The flexible film contains integratedly the flexible printed circuit by an in-mould injecting mode. The flexible film has an outer surface for touch control. The outer surface is configured for being pressed for driving the touch control circuit of the flexible printed circuit to output signals. Therefore, the present touch module is manufactured simply, and has a thin thickness.
1. An in-mould molding touch module comprising:
a flexible printed circuit having a touch control circuit; and
a molding flexible film containing integratedly the flexible printed circuit by an in-mould injecting mode, the flexible film having an outer surface for touch control, said outer surface having a plurality of pressed portions for distinguishing a touch control position of the flexible printed circuit, said touch control position having a first conducting terminal oppositely displaced from a second conducting terminal to define a gap therebetween;
whereby each of said pressed portions has a pressed key formed thereon and applying a downward pressure on said pressed key deflects said first conducting terminal to contact said second conducting terminal;
wherein the outer surface is configured for being pressed to drive the touch control circuit of the flexible printed circuit to output signals and the outer surface and the pressed portions are one-piece.
2. The in-mould molding touch module as claimed in claim 1 , wherein the flexible film is made of rubber.
3. The in-mould molding touch module as claimed in claim 1 , wherein the molding flexible film further comprises an inner surface for supporting.
4. The in-mould molding touch module as claimed in claim 3 , wherein the inner surface has a plurality of supporting portions for supporting the flexible film and the flexible printed circuit and corresponding to the pressed portions respectively, and the inner surface and the supporting portions are one-piece.
