3M係利用120HzLCD顯示器,將全畫面解析度(Full Resolution)的左、右影像以「Frame Sequence」的方式顯示於其3D(3D Film)的背面。

3D膜的構造:上方是圓頂形狀,背面是菱鏡結構。3D膜係安置在左、右兩側各有一組LED光源的導光板上。

其工作原理:當左側LED光源亮時,右眼可以看到左光源;而當右側LED光源亮時,左眼可以看到右光源。3M就是利用此導光結構,巧妙地將左、右眼影像的顯示與LED光源同步。當左側LED的光源亮時,顯示右眼影像給右眼觀賞;而當右側的LED光源亮時,則顯示左眼影像給左眼觀賞。

更進一步,它可以將左、右兩側的LED光源同時點亮,來顯示一般2D影像,如此就可以達到2D/3D顯示切換的功能。

我個人看法:由於沒有看到實物展示,很難評論其3D品質與效果(是否會像「Parallax Barrier」的技術有觀賞角度的限制?);不過從它的工作原理來評估,其成本應該不會太便宜,如果3M已開始大量生產此產品給中、小尺寸LCD面板來應用的話,我倒是樂觀其成。畢竟,3D產業的確是需要更多重量級的國際大廠來開路,如此這個產業才得以蓬勃發展。

3M Film Realizes 3D Panel Viewable With Naked Eye

Sumitomo 3M Ltd exhibited an optical film that can realize a 3D LCD panel viewable with the naked eye at FPD International 2009.

The film does not sacrifice spatial resolution and enables to easily switch between 2D and 3D representations. Sumitomo 3M has already started volume production of the film for small- and middle-sized LCD panels, and the film has already been adopted for some devices.

Dome-shaped lenses are seen on the top side of the film, and the back side has prism-like structures. When the film is placed on the light guide plate of an edge-lit backlight unit that has LED light sources on the right and left sides of a panel, directionality is added to the backlight.

Sumitomo 3M utilized the directionality so that the light from the left LED light source comes to the right eye and the light from the right LED light source comes to the left eye. And the company enabled to view 3D images with the naked eye by synchronizing the lighting of the left LED light source and the display of the image seen by the right eye (and the lighting of the right LED light source and the display of the image seen by the left eye).

Furthermore, it is possible to show 2D images by using the right and left LED light sources at the same time and displaying the same image for both the right and left eyes. Therefore, it is easy to switch between 2D and 3D images.

At the exhibition site, Sumitomo 3M showcased 9- and 2.8-inch LCD panels equipped with the new film.
