QLED
Quantum dot screen
QLED is a display technology using quantum dots—microscopic semiconductor particles that emit precise colors when illuminated by a backlight.
Samsung trademarked the term for its premium televisions, though the underlying technology appears in other brands.
QLED screens typically offer brighter, more vivid colors than standard LED displays: The QLED TV made the nature documentary look stunning.
