<p><P>PROBLEM TO BE SOLVED: To materialize a touch panel of high resolution regardless of its narrow "frame". <P>SOLUTION: A touch panel 30 includes: a light-emitting sided-optical waveguide 33; a light-receiving sided-optical waveguide 34; and an electromagnetic induction-type digitizer 36. A position coordinate is recognized using an electronic pen by an electromagnetic induction-type digitizer 36 when high resolution is required. A position coordinate is recognized using a finger by the optical waveguides 33 and 34 when high resolution is not required. This makes it possible to materialize the touch panel 30 having a high resolution and a lower power consumption regardless of its narrow frame. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
