Your Toshiba glasses are showing 60 FIELDS per sec, compared with 48 or 96
fields/sec at IMAX, where each field is truly a 'frame' of film. 

I, too, have been led to believe that each frame of film is double
shuttered, yielding 96 alternations/sec, thus no noticable flicker.  There
is also considerably less brightness on an IMAX screen, compared with a TV,
further helping in flicker reduction.
