A touch screen, a touch system and a method for positioning a touch object in a touch system are disclosed. The touch screen comprises an infrared pair tube array, wherein said infrared pair tube array is disposed on an edge of said touch screen. By introducing the infrared pair tube array, the touch screen of the present invention eliminates invalid touch areas in the existing touch screen and avoids false touch points in multipoint positioning.
