# 2 The 3D Television

3D television conveys depth perception to the viewer by employing techniques such as stereoscopic display, multi-view display, 2D-plus-depth, or any other form of 3D display. 

The prices of these televisions are quite high, anywhere from $1,500 to nearly $40,000. Also, many of the televisions required glasses to see 3D films which caused discomfort.

Some viewers complained of headaches, seizures, and eyestrain. After years of promotion and product releases from TV manufacturers, the product was dropped.
