LED-backlit LCD - online puzzles

A LED-backlit LCD is a flat panel display which uses LED backlighting instead of the 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 quantum dot enhancement film (QDEF)), more rapid response to changes in 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.
