23 inch HDTV televisions are monitors that support HD, or high definition, technology. The television’s screen measures 23 inches diagonally across the screen. The ‘HD’ refers to high definition, a video resolution substantially higher than that of standard definition (SD) televisions. High definition has nearly five times the pixels per frame than standard definition, at around 1 to 2 million pixels. http://www.howstuffworks.com/hdtv.htm
HDTV technology was first introduced to the US market in the 1990’s. Testing on HD technology in the US was completed in August of 1994, and the first public HD broadcast occurred on July 23, 1996. http://www.hidefster.com/history/
LCD versions of HDTV use liquid crystal displays to allow thinner and lighter televisions and monitors. Plasma TVs provide a higher level of contrast than LCD versions. LCD televisions tend to be less expensive than Plasma. http://www.howstuffworks.com/hdtv.htm
In 2009, the state of California banned the sale of Plasma television sets, alleging that they consumed too much energy and that their LCD counterparts were much more energy efficient. The first wave of the regulations will begin in 2011. This announcement caused retailers to sell Plasma television sets at highly discounted prices during the Christmas shopping season, and to continue to offer them at discount prices in an attempt to liquidate inventory. http://news.yahoo.com/technology/
