ABSTRACT:
There is provided an information display device in which speed of detecting input coordinates on a display screen is increased. A coordinate detection circuit 7 detects indication coordinates at a tip end of an electronic pen 6 based on an induction voltage induced at a detection electrode of the electronic pen 6 in scanning a row electrode G and a column electrode S. A coordinate output circuit 17 obtains indication coordinates at the tip end of the electronic pen 6 based on a movement amount detection signal from a movement amount detecting section 20 of the electronic pen 6. A coordinate signal generating circuit 18 outputs an x-coordinate signal and a y-coordinate signal by combining the indication coordinates detected by the coordinate detection circuit 7 and the indication coordinates obtained by the coordinate output circuit 17. Thus by filling an interval between the indication coordinates detected by the coordinate detection circuit 7 with indication coordinates obtained by the coordinate output circuit 17, an apparent detection speed of the input coordinates can be increased.
