<p>PURPOSE:To make coordinate detection at an input part excellent, to eliminate misinput and to make a display easy to see by providing transparent conductors which are different in thickness between a display part and an input part so as to cut off a disturbing noise signal. CONSTITUTION:This input device consists of the input part 1 for inputting optional handwriting information on characters, figures, etc., a drawing display control part 5 which processes the input data numerically, the display part 3 which displays the data from the drawing display control part 5 and the lattice-shaped transparent conductors 2 which cut off the influence of the disturbing noise signal generated at the display part 3 on the input part 1. Further, the transparent conductors 2 are provided between the display part 3 and input part 1. For example, the transparent conductors 2 are formed in a lattice shape and lattice holes 2a are square. The lattice-shaped transparent conductors 2 are put between the input device 1 and display device 3, which consists of respective display pixels 3a. Further, the respective lattice holes 2a correspond to the respective display pixels 3a of the display device 3, one to one, and so arranged not to disturb light from the display device 3.</p> |
