<P>PROBLEM TO BE SOLVED: To obtain an input display system including a large curved surface display and an optical touch panel. <P>SOLUTION: An input display system 10 comprises: a curved surface display 12; a light-emitting element radiating an infrared beam 22; a light-emitting side optical waveguide 13; a light-receiving side optical waveguide 13; and a photoelectric conversion element. A display screen 11 is a curved surface 17 comprising a trajectory of a single line segment 15 moved in a direction perpendicular to an axial direction 16, while the line segment is kept in a constant state with respect to the axial direction. The display screen 11 includes a pair of curved line sides 18, 19 and a pair of linear sides 20, 21. The light-emitting side optical waveguide 13 is arranged along one curved line side 18 of the display screen 11 and radiates an infrared beam 22 parallel to the linear sides 20, 21 of the display screen 11. The light-receiving side optical waveguide 14 is arranged along the other curved line side 19 of the display screen 11 and receives the infrared beam 22 radiated from the light-emitting side optical waveguide 13. <P>COPYRIGHT: (C)2013,JPO&INPIT |
