Managing Light to Increase Efficiency in LCDs
Brightness-enhancement films are used in novel ways to overcome challenges posed by larger, brighter displays.
by William K. Smyth, 3M Optical Systems Division
Consumers plan to purchase 72 million LCD TVs in 2007 and 98 million in 2008, when sales will surpass cathode-ray tube TV unit sales for the first time, according to the research firm DisplaySearch of Austin, Texas. The industry is racing to build appliances to meet the demand and to deliver the stunning picture quality that buyers expect.
Today, consumers want large LCD TVs with full-high-definition progressive scan, wide color gamut and fast response times. Full high definition is defined by a resolution of 1920 × 1080 pixels. There are two types of full high definition: interlace technology, or 1080i, which creates a picture on an every-other-line basis, and progressive scan, or 1080p, which paints the picture on a line-by-line basis. Most full-high-definition LCD TVs are progressive scan.
