MacBook Air Spurring LED Use in Screens: DisplaySearch

The MacBook Air has become the best advertisement for why companies should use LED (light-emitting diode) backlights in notebook screens, and is driving adoption, according to market researcher DisplaySearch. LED backlights in display screens are an improvement over old CCFL (cold-cathode florescent lamps) technology for several reasons, including a stunning picture due to more vibrant contrasts, better power savings, and they're easier on the environment because they contain no mercury and last longer.

Once Bright Future Beginning to Dim, LED Lighting is Partly to Blame for Neon's Decline

Approaching Light Design Neon in Chelsea, it's hard to tell whether it's still in operation. A glowing pink and turquoise sign reading "Neon" hangs in the window, but lower down, so does a more sober "For Sale" notice. Inside, a colossal Marilyn Monroe fixture smiles down from the back wall, alongside images of Mufasa and Simba from "The Lion King." Out-of-service signs from a money-transfer shop and the nearby Katz Bagel Bakery lean against the shelving below.

On Hight Power LED Flashlight

LED flashlight is a new type of illumination instrument that uses light emitting diode as light sources, with merits of power-saving, long lifespan and high brightness. Immediately after White LED was invented, LED flashlight came into the market. Initially, WLED was only applied on part of military materials, daily uses of it were not widespread as it is expensive and with low brightness. Along with the improvement of its brightness and the lowering of its cost, WLED becomes more and more popular.
