Abstract: An electromagnetic input LCD monitor is disclosed in this invention. The electromagnetic input LCD monitor includes a back frame and a film antenna module. The back frame has at least one opening. The film antenna module includes a film antenna plate and a signal receiving module. The film antenna plate is disposed on a surface of the back frame; the signal receiving module is disposed on the other surface of the back frame. The film antenna plate has a wiring portion which is connected with the signal receiving module through the opening.

Abstract: An electromagnetic antenna loop layout for use with an electromagnetic input apparatus is disclosed. The electromagnetic antenna loop layout comprises a plurality of electromagnetic antenna loops in parallel in each other, wherein each electromagnetic antenna loop has a first terminal connecting to a switch, and at least two adjacent electromagnetic antenna loops has a second terminal connecting to a common end (COM).

Abstract: The present invention relates to a whiteboard and method for orientation thereof, and particularly relates to an electromagnetic-and-interactive whiteboard with a battery-free pointer device and method of the electromagnetic-and-interactive whiteboard for finding the position of the battery-free pointer device. A plurality of signal handling devices are provided in the whiteboard for controlling the antenna boards of the whiteboard to emit electromagnetic power respectively. By this way, the antenna boards do not interfered with each other and the battery-free pointer device can be located precisely without deviation. Furthermore, the electromagnetic power provided by the antenna boards is applied to instead of a battery in battery-free pointer device for providing the power to the battery-free pointer device. The electromagnetic power provided by the antenna boards is used to be the power of the battery-free pointer device for emitting electromagnetic signals.
