Full-Ar­ray vs Edge-Lit

Gadgets and Gizmos (India) - - KNOW TECH -

Not all LED TVs utilise LEDs in the same way. Now, there are two pri­mary forms of LED light­ing tech­nol­ogy that LED TVs can utilise: full-ar­ray LED back­light­ing and edge-lit LED back­light­ing. Also known as lo­cal-dim­ming tech­nol­ogy, full-ar­ray tech­nol­ogy em­ploys ar­rays or banks of LEDs that cover the en­tire back sur­faces of LED TV screens. In con­trast, edge-lit tech­nol­ogy em­ploys LEDs only around the edges of LED TV screens. Un­like an edge-lit LED TV, an LED TV with full-ar­ray tech­nol­ogy can se­lec­tively dim spe­cific groups of LEDs, al­low­ing for su­pe­rior con­trast ra­tio and su­pe­rior over­all pic­ture qual­ity.
