POLARIZATION GLASSES, SPECTROSCOPIC GLASSES, DISPLAY DEVICE AND METHOD, AND PROJECTION DEVICE AND METHOD

摘要

PROBLEM TO BE SOLVED: To solve the problem that, when displaying an image in a time division manner, an increase of observers causes a display frame rate to decrease, and thus, flicker occurs in an image that the observers see and the image quality deteriorates.SOLUTION: A pair of polarization glasses controls, with a shutter, transmitted light in synchronization with a display device including plural films having different polarization characteristics, the pair of polarization glasses having at least one of the plural polarization characteristics.
