Abstract
A structure of a prepositive electromagnetic tablet with a transparent antenna and the method for fabricating said prepositive electromagnetic tablet with a transparent antenna is disclosed. The electromagnetic tablet according to this present invention comprises a durable transparent substrate, a transparent antenna layer, and a transparent protective layer. Further, the above-mentioned electromagnetic tablet can be applied in front of LCD panel (at the user'"'"'s side). Therefore, it is more convenient regarding the function of hand-written input and hand-written drawing, which can be directly performed on a displayer.
