FPR – film patterned retarders – is the latest 3D TV technology.  FPR uses an LCD display.  However, unlike a traditional liqud crystal display, FPR 3D TV converts light so that it can display as both left and right images at the same time (every other horizontal line is used for each eye).  This avoids a number of shortcomings over traditional LCD 3D TVs:

1.  With FPR 3D TVs, one can display an entire frame at one time, unlike traditional LCD displays which require a left frame, followed by a black frame, followed by a right frame, followed by another black frame.

2.  Less ghosting occurs because the left and right images are displayed at the same time unlike with traditional LCD displays, which display the images consecutively.

3.  Slower refresh rates are needed on FPR 3D TVs – they need only be 1/4 as fast, as one needs only 1 frame instead of 4 with traditional LCD displays.  This also reduces flicker.

4.  Increased brightness through the elimination of the black frames used for traditional LCD displays.

5.  Lighter, more comfortable 3D glasses, as the glasses for FPR 3D TVs do no need to be as complicated as with traditional LCD displays.  This should also make the 3D glasses cheaper.

The one big drawback of FPR 3D TVs is decreased resolution, as only half of the screen is used for the display for each eye.  This is unfortunate, but the benefits listed above should outweigh this disadvantage and offer consumers a higher quality 3D experience.

It will be interesting to see what effect FPR has on the 3D TV market.  LG has announced that next year (2011) it will be launching new 3D TVs using FPR technology.
