Better Improvements and benefits for LED backlighting
By Phil Conner
LCD TVs traditionally have used CFL fluorescent lighting as the back lighting source to illuminate the front LCD twisting crystal panel. These lights have come with many challenges over the years such as side angle viewing issues, hazy black levels, and low contrast. All of these challenges have been typically improved upon by LED back lighting though manufacturer model and make still have a lot to do with quality performance of the TV.
LED backlighting in TVs presents many potential advantages over incandescent flourescent light sources including lower energy consumption, longer lifetime, improved robustness, smaller depth size, quicker switching, and stronger durability and reliability. LEDs powerful enough for room lighting are relatively expensive and require more precise current and heat management than compact fluorescent lamp sources of comparable output.
Advantages over plasma TV technology have typically been in the energy usage department and the thin design area while at the same time matching or coming close to plasma performance in contrast. Peak whites are another advantage over both LCD and Plasma.
These potential advantages are the reason so many manufcturers of TVs have latched on to the technology as prices for LED lamp lighting has decreased. More and more LCD TVs have LED based backlighting. Check out these links for a couple of very good value oriented sources for the Best LED TVs ratings and LED TV Reviews.
