LED-backlit LCD

A flat panel display that uses LED backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting.

A LED-backlit LCD is a flat panel display that uses LED backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting. LED-backlit displays use the same TFT LCD (thin-film-transistor liquid-crystal display) technologies as CCFL-backlit displays, but offer reduced energy consumption, better contrast and brightness, greater color range (using more expensive RGB LEDs, blue LEDs with RG phosphors, or a quantum dot enhancement film (QDEF), more rapid response to changes in a scene (with dynamic backlight dimming), and photorefractive effects.

While not an LED display, a television using such a combination of an LED backlight with an LCD panel is called an LED TV by some manufacturers and suppliers.

Advantages

  • Wider color gamut (with RGB-LED or QDEF) and dimming range
  • Very slim (some screens are less than 0.5 inches (13 mm) thin in edge-lit panels)
  • Significantly lighter and cooler, as much as half the total chassis and system weight of a comparable CCFL
  • Typically 20–30% lower power consumption and longer lifespan
  • More reliable
