<p><P>PROBLEM TO BE SOLVED: To correctly detect the coordinates of a designated point not in a resistance film system or electrostatic induction system but in a totally new system in a coordinate detecting device for detecting the position of coordinates pointed in contact on a plane. <P>SOLUTION: Every pixel 121, 122 or the like on a display input panel(display screen) 11 is provided with display elements (R) 13r, (G) 13g and (B) 13b of R, G and B three original colors, and a pen top detecting part 14 where a light emitting element 14a and a light receiving element 14b with infrared wavelength are combined and arranged is adjacently arranged, and when a pen top P1 is butted to a panel 11 face according to a pen operation on the display screen by a user, an infrared ray Xa emitted from the light emitting element 14a of the pen top detecting part 14 of a pixel 12n at the butted position of the pen top P1 is reflected on the pen top P1, and the reflected light Xb is received by a light receiving element 14b of the pen top detecting part 14 so that the light reception signal of the pen top detecting part 14 of the pixel 12n can be fetched as a pen top detection signal, and that the pen input coordinate position can be detected. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
