Modern 3D TVs come in many forms and designs. While they can be broadly categorized according to their 3D rendering techniques, most models are actually assembled from LED-lit or plasma panels just like normal 2D TVs. The screen types will not only determine the 3D picture quality, but also many other general characteristics. These can range from form factor to power efficiency and affordability. These derivatives of LCD panels are extremely popular among 3D TV manufacturers and newer sport LED lighting instead of traditional florescent lamps. They come in many permutations but can be broadly categorized by their 3D display technologies and backlighting types. Available from 32 to 68 inches, most models also offer a full-HD screen resolution, but that cost higher than the plasma siblings. We've mixed impressions of these displays as far as 3D picture quality is concerned.
While most models we reviewed delivered convincing 3D depth with smooth motion to boot, flickering is a major problem for active shutter 3D glasses. Note that the passive version does not exhibit this issue and can display brighter 3D pictures as well. 3D LED TVs are also behind 3D plasmas in terms of contrast and black-level, though the performance gap is smaller for premium LED-backlit models with local dimming. However, 3D LED TVs are generally slender and more power efficient than 3D plasmas
