<p>A 3D/2D display device switching module installed to the front side of a display device includes a first axle and a second axle installed on both sides of the display device respectively, and a thin film unit looped between the two axles. The first axle is coupled to a first power source. The thin film unit has a transparent area and at least one grating area. After the first power source drives the first axle to rotate clockwise or counterclockwise, the transparent area or the grating area is switched to align with the display device to produce a 3D/2D display effect. In addition, the present invention further includes a containing box installed at the backside of the display device for stacking and accommodating the thin film unit with more different types of grating areas.</p> |
