interactive touch screen 65 inch.Preclude the use of the recording is determined herein, the touch position , and then to eliminate false touch point is touched according to the order , from the accurate coordinate points. Implementations only body follows : for in , when the A point and the D point are touched simultaneously , first according to the touch action A point and D have different events on the point, the recording position of a touch action Dir Coordinates , recorded as point A (X 1 , Y 1 ), and save this touch point. When the second touch operation is superimposed on the first touch operation, the microprocessor will be a plurality of sets of position coordinates (X- . 1 , X- . 1 , an X2 , Y2 ), from the a new touch point determination added by Compare existing position coordinates (X 1 , Y1 ), DCoordinate point is not possible with the A point in either direction from the parallel and exclude other coordinate (X- . 1 , Yl ), (X- 2 , Y2 ) possible. From this, it is determined that the coordinate of the other touch point D is (X 2 , Y 2 ),
