RF RF shutter 3D glasses At present, most of the active shutter 3D TVs use infrared to synchronize with 3D glasses, but this also leads to a problem, that is, if the receiver of the glasses is not aligned with the infrared emitter on the TV, then the glasses will not work normally, and the audience will not be able to see stereo vision, although this problem will not have obvious interference with the enjoyment of 3D programs in most cases, but at some special angles and when the audience often moves, The impact is more pronounced.

The best solution to this problem seems to be to replace infrared transmission with RF radio frequency. Because RF transmission is a relatively mature short-range wireless transmission technology, there have been some color TV manufacturers who have used RF technology on the remote control to solve the operation problem of long-distance across obstacles.

A few days ago, South Korea's Samsung company exhibited a shutter-type 3D glasses using RF radio frequency technology. With a total weight of only 28g, these glasses are very light to wear. However, these glasses require a 3D TV to upgrade the synchronous signal transmitter, so it will not be mass-produced in a short period of time.
