2 manufacturers, LG and Vizio, are using passive 3d technology. All others are currently selling active 3D systems.
LG aren't using the latest technology in 3D. The passive glasses are polarizing lenses and operate in the same way that film based 3D movies have been doing for many years. LG have called this "Cinema 3D" in recognition of the fact it has come from cinema technology. The latest 3D technology is being used by most other manufacturers who are using active glasses. This technique retains full resolution in the images rather than LG's system that cuts effective resolution down to only 540 lines.
LG Cinema 3D is called the next generation 3D TV for marketing purposes. The the polarizing technology of the LG system has been with us for many years so it's anything but next generation. LG use passive 3D technology while most other manufacturers use active. Active technology does not use polarized light but does use glasses that cut the image from one eye to the other at high speed.
It is because the world is dependent on it. Like you, For example you are using technology to find the answer.

At present only LG is using it in their TVs.May be in nearby future other manufacturer will use this technology in their 3D TVs

Modern technology relies on CFC's for many processes not restricted to Automobile Air Conditioning. To stop using and producing these chemicals you would need to completely stop modern technology
Samsung, like the majority of manufacturers only makes active 3D tvs. LG and Toshiba make passive 3D TVs. Although there is debate over the better technology, manufacturers are supporting active 3D more than passive. It has had some teething trouble in its early days but recent developments have made it far more robust and the once heavy glasses are now as light as many of the passive glasses.
