HD News: With the arrival of mature LED TV technology, the purest deepest blacks may no longer be the preserve of Plasma screens.
LED TVs are actually LCD TVs that no longer use the traditional always-on single backlight but replace it with a myriad of individual LED backlight arrays.
The advantage of this approach is that individual LED segments can be turned on or off for improved screen performance and ultimately better black levels.
LED technology also improves the motion handling capabilities of LCD’s, in particular their problems with “motion blur” as well as providing a much richer and greater range of colour.
LCD TV’s with LED are nothing new, but a refinement of the technology, RGB LED backlighting is under development by a number of manufacturers. RGB backlighting uses controllable LED lights which offer full-colour RGB LED dimming rather than ‘black & white’ only dimming.
