3M Optical Film Cuts LCD TV Energy Consumption 20-30 Percent.SAN FRANCISCO San Francisco (săn frănsĭs`kō), city (1990 pop. 723,959), coextensive with San Francisco co., W Calif., on the tip of a peninsula between the Pacific Ocean and San Francisco Bay, which are connected by the strait known as the Golden -- Today 3M announced that one of its optical films could save as much as 57.5 billion kilowatt-hours (kWh) of energy for LCD TVs sold over the next five years. The film -- Vikuiti Dual Brightness Enhancement Film D400 (DBEF (Dual Brightness Enhancement Film) A film from 3M that increases the brightness of LCD screens. The film recycles most of the light that is normally lost in the rear polarizer. D400) recycles light, reducing the number of light bulbs required and increasing the overall energy efficiency of LCD TVs 20 to 30 percent. "This is good news for the industry," says Andy Wong Andy Wong can mean the following people:
With the market for LCD TVs growing as much as 70 percent per year, 315 million LCD TVs over 21 inches in size are expected to be sold worldwide between 2006 and 2010, according to estimates from DisplaySearch, a leading flat panel display A thin display screen for computer and TV usage. The first flat panels appeared on laptop computers in the mid-1980s, and the LCD technology became the standard. Stand-alone LCD screens became available for desktop computers in the mid-1990s and exceeded sales of CRTs for the first time (FPD (1) (Flat Panel Display) See LCD, plasma display, EL display, FED and flat panel display. (2) (Field Programmable Device) An umbrella term for all chips that can be programmed by the customer including SPLDs, CPLDs and FPGAs. See PLD. ) market research firm. By saving an average of 36.5 kWh per year for each LCD TV, 3M's film could potentially save 57.5 billion kilowatt-hours of energy over the life time(a) of the LCD TVs sold from 2006 to 2010. That is equal to the energy produced by 33 million barrels of oil or 23 million tons of coal. 3M makes a range of Vikuiti brightness enhancement films that maximize the light efficiency of liquid crystal displays (LCDs) in computer monitors, notebook PCs, cell phones and PDAs as well as televisions. It developed the world's first brightness enhancement film for LCDs in 1993. Called Vikuiti Brightness Enhancement Film (BEF BEF The ISO 4217 currency code for Belgian Franc. ), the unique substrate enables bright, readable notebook computer screens that require less battery power to operate.
