Claim Text:
1. A light guide module, comprising: a light guide plate, comprising a light-exit surface and a bottom surface opposite to the light-exit surface; a metal layer, comprising an upper surface and a lower surface, the upper surface attached to the bottom surface of the light guide plate, wherein when light is incident onto the upper surface of the metal layer, the light is reflected back into the light guide plate, and when an electromagnetic wave reaches the lower surface of the metal layer, the metal layer shields the electromagnetic wave from propagating; an insulation layer, substantially covering the lower surface of the metal layer, wherein at least one ground window is formed in the insulation layer to expose the metal layer; and a light module having a conductive contact and a light source, the conductive contact electrically connected to the ground level and facing toward the ground window so as to be electrically connected to the metal layer through the ground window, the light source facing toward the light guide plate and outputting the light wherein the light module is utilized for keeping the conductive contact facing toward the ground window.
