Myth: Aren't LCD and LED the same kind of TV?
Reality: LED TVs and LCD TVs are very similar in construction, as both employ a flat-screen with LCD (liquid-crystal display) technology. However, the way they create light for televised images is very different. An LCD TV uses a type of fluorescent backlighting, while an LED TV uses LED (light-emitting diode) backlighting. As a result, LED TVs generally produce deeper blacks than conventional LCD TVs, and may also provide more energy efficiency. Read more at LED TVs Explained.
Myth: Unlike a plasma TV, it's okay to lay an LCD or LED TV flat when transporting in a car
Reality: Larger LCD and LED TVs are constructed to have their weight balanced when set upright. So if you lay the screen flat, there won't be adequate support in the middle, which can lead to cracking or distortion on the edges if left that way over time. Add in the vibrations while driving a car, and the chance of cracking or distortion only increases.
