HDTV is the highest digital form of television also known as “High-Definition television”. It has a 16:9 aspect ratio, whereas an SDTV has a 4:3 ratio. For example, its ratio is the same as a movie theater screen. Having the same aspect ratio as a movie theater screen is one of the biggest selling points. HD has three different types of resolution: 720p, 1080i and 1080p. These three types of resolution represent how many pixels each contains, the more pixels, the better the image. 1080 is the best right now. Besides different types of resolution there are also different types of HDTV (Torres).
The first type of HDTV is direct view CRT. It’s the same design as older TVs but still has the 16:9 ratio and is capable of displaying HD resolution. The typical size of a CRT ranges between 27 and 30 inches (Grant). The second type of HDTV is plasma which is a flat panel screen. It’s called plasma because each pixel contains three cells typically ranging between 37-71 inches. Another type of HDTV is LCD. LCD is a flat panel and its size typically ranges 13-65 inches (Katzmaier). “LCD” stands for “liquid crystal” and has three pixels subparts of RBG. DLP, the fourth type, is a rear projection TV that uses digital light processing technology with the typical size anywhere from 37-73 inches. The process consists of a bulb that shines light through a spinning color wheel onto thousands of tiny mirrors and reflects light onto the screen (Grant). Despite the fact there are several types of HDTV its popularity is rapidly growing.
In 2003 HDTV sales were around 3.2 million. In 2004 Americans bought between 6 and 7 million HDTVs. This was an increase of more than 50% compared to the numbers in 2003. In 2003 it was predicted that the number of HDTVs sold would be around 20.2 million in 2008 (Latest High-Definition). Interestingly enough, in U.S households in 2008 it was recorded that there were 28 million HDTVs currently in possession. A recent survey shows that 5.5 of that 28 million purchased their first HDTVs during the 2007 holiday season. Of these 5.5 million 3 million bought their second HDTV within less than a year of purchasing their first HDTV (Hughes). After being interviewed Senior Vice President of Newswires said that their company believes that there will be a jump in HDTV demands” (Library Research Database).
As of right now the future of HDTV is Sony’s OLED. OLED stands for “organic light-emitting diode”. This type of HDTV is powered by organic compounds that emit their own light therefore it requires no backlight. This allows the TV to last longer than any other TV. It is the tinniest TV because it is only 3mm in width (the size of three credit cards). It is expected to be shipped out in the next year (McKnight).
