<p>Electronic white board having electromagnetic sensing layer of conductor grid,includes a writing input,portion,a frame portion and a control circuit portion.The writing input portion, multilayer and in the frame,includes a handwriting layer,an input sensing layer and a base layer.The input sensing layer which output to the control circuit is between the handwriting layer and the base layer.The sensing layer is conductor array in which the conductor is coiled along X,Y axis respectively and the crossing points of the conductor are insulated with each other.The space surrounded by the coiled conductor forms a sensing unit.The structure in the present invention is simple and usable,easy to produce and decreases the cost of electronic white board. Furthermore, electronic white board in the present invention could be portable,convenient to place.</p> |
