Abstract

A touch apparatus with anti-electromagnetic interference structure comprises a touch panel and a metal grid. The touch panel comprises at least a substrate. The metal grid is located between the substrate and a display panel. The metal grid is composed of a metal net and a metal frame. The metal frame surrounds the four sides of the metal net. A contact point is formed on the surface of the metal frame opposite to the substrate. The contact point and a ground source are electrically connected. The metal net is formed by interweaving a plurality of metal wires. The interweaving angle of the plurality of metal wires is 45 degree or 135 degree. The metal grid is fixed to a surface of the substrate by optical glue, and the grid space of the metal net is filled with the optical glue. As such, a touch apparatus with anti-electromagnetic interference structure is formed. Since the metal grid is formed with the contact point for grounding, it can be closer to the ground source for forming electrical connection without using an additional conductive copper foil or aluminum foil. Therefore, the present invention reduces cost and simplifies the structure and production process for the touch device, which facilitates the circuit design and grounding assembly.
