Liquid-crystal display televisions (LCD TV) are televisions that use LCD technology to produce an image. The technology used is generally TFT, because this allows for reduced size, especially depth reduction. Benefits also include lower weight and reduced energy consumpton when compared to other display types. LCD televisions by nature can be and are often used as computer monitors.
It had been widely believed that LCD technology was suited only to smaller sized flat-panel televisions at sizes of 40" or smaller. Early LCDs could not compete with plasma technology for screens larger than this because plasma held the edge in cost and performance. However, LCD TVs can now offer essentially the same performance.
Current seventh-generation panels by major manufacturers such as Samsung, Sony, LG.Philips LCD, and the Sharp Corporation have announced larger sized models:
In October 2004, 40" to 45" televisions became widely available, and Sharp had announced the successful manufacture of a 65" panel.
In March 2005, Samsung announced an 82" LCD panel.[1]
In August 2006, LG.Philips Consumer Electronics announced a 100" LCD television[2]
In January 2007, Sharp displayed a 108" LCD panel branded under the AQUOS brand name at CES in Las Vegas.[3]
Manufacturers have announced plans to invest billions of dollars in LCD production over the next few years, with televisions expected to be a key market.
Improvements in LCD technology have narrowed the technological gap, allowing producers to offer lower weight and higher available resolution (crucial for HDTV), and lower power consumption. LCD TVs are now more competitive against plasma displays in the television set market. It is noted that LCDs are now overtaking plasmas, particularly in the important 40" and above segment where plasma had enjoyed strong dominance.[4][5]
