The disclosure describes a touch device including a touching area having a first edge and a second edge; two reflective lens arrays and two laser source modules which are all disposed at the first edge and the second edge respectively, wherein each laser source module includes a laser diode and a diffractive optical element assembled in front of the laser diode for separating a laser beam projected from the laser diode to a plurality of laser beams with equal magnitude, the laser beams are distributed in a parallel arrangement over the touching area by the reflective lens array; and two receiving devices disposed at the corresponding edges of the first edge and the second edge respectively. The receiving device includes a plurality of sensing units, wherein each sensing unit receives one of the laser beams respectively.

Touching device, laser source module, and laser source structure thereof

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.
