Full-Array vs Edge-Lit
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.
