Dual LED is a Samsung-developed technology that combines edge-lit and back-lit backlighting technologies to enhance contrast and color reproduction in their television. This mid-range feature combines warm and cool LED backlights and can balance color and brightness more accurately than a standard edge-lit screen. Dual LED also produces a wider viewing angle and varied color temperatures that can be matched to the content. This backlighting technology also has reduced light leakage for a more efficient and adaptable screen.
