摘要
The coordinate input device of the present invention includes a sensing panel that has a plurality of sensing strip antennas, and a sensing control circuit that controls the sensing panel to sense a touch input and calculate corresponding touch input coordinates to provide the coordinates to a host. The coordinate input device of the present invention may also include a sensing control circuit that calculates touch input coordinates based on a variation in electrical characteristic values related to the impedance matching of a scan signal with respect to the touch input of an electrostatic object, and senses all of the touch inputs of the electrostatic object and a stylus pen by using the same and one sensing panel without having a separate digitizer panel for sensing the respective touch inputs of the stylus pen, by using the change function of a touch sensing mode.
