LED TV Technology Pros and Cons
by Robert Wiley
- The viewing angle on LCD Televisions with LED back lighting has improved dramatically to plasma-like levels of 75 degrees with no contrast level degradation on some of the best ones.
- The black levels on the best new LED TVs has improved to plasma like black levels while contrast levels still lag the best plasmas buy hundreds of post calibration points
- Brightness on LED based LCDs is better than the traditional flourescent bulbs
- LED TVs will have better consistency of color information over time than traditional LCDs
- LED backlit Televisions should in theory have a better lifespan than traditional LCD TVs or plasmas.
- LED TVs with local dimming use more energy than traditional LCDs. It's not much, about 100W for a particular size range.
- LED Televisions with discreet backlighting can have lots of dimensional depth to the cabinet. We recently reviewed one with a 6" depth to the cabinet – making it less wall mount friendly.
- LED TVs are quite a bit more expensive than traditional LCD TVs. See our article titled "LED TV – Is it worth it?" or our "LED vs LCD" coverage.
