Abstract
A digitizer includes a flat panel medium with which a stylus contacts for information input, an outputting device for visualizing and outputting information according to the information input by the stylus, and a resistor installed between the outputting device and the flat panel medium in a predetermined pattern, wherein a flat panel glass substrate having a predetermined thickness is laminated on the outputting. The resistor has a predetermined conductivity and is laminated on the glass substrate in a predetermined pattern, and a thin film dielectric layer is laminated on the patternized resistor.
Claims4
