When it comes to HD TVs and Plasma televisions, you have to look into more than the outer appearance of each to understand the differences between the two types of televisions. They both utilize different technology to deliver nearly the same results.
Plasma TV technology is based in part on the fluorescent light bulb. The display of the Plasma TV is composed of cells and within each cell there are two glass panels that are separated by a thin gap where during the manufacturing process the neon-xenon gas is injected and sealed in plasma form. The gas is electrically charged at certain intervals when the Plasma set is being used and the charged gas then hits green, red, and blue phosphors which in turn produce the TV image you see. Each group of green, red, and blue phosphors is referred to as a pixel.
Getting a plasma TV means you do not have to have the electron beam scanning and bulky picture tube of the traditional television since this TV uses the burning of phosphors to produce the image. However, plasma televisions are susceptible to heat generation and screen-burn of static images. The benefits of plasma TVs are the larger screen sizes, better contrast ratio and deeper blacks, improved color accuracy and saturation, and improved motion tracking. As well, Plasma TVs display up to 16.77 million colors to provide a highly lifelike picture. Another advantage of the Plasma TV is its thin, flat-panel design and they are very light. The Plasma TVs space-saving design allows you to move it easily as well as placed in areas that no other type of TV would fit. Plasma TV prices have fallen and are now very affordable.
HDTV is the next step up from digital television. HDTV stands for High Definition Television. HD TVs provide clearer image signals. There are about two million pixels being delivered through this digital signal. You will receive more precise and sharp images. HDTV has a higher resolution and this enhances the image sharpness. HDTV offers a wider image than traditional televisions which enhances the experience of watching movies and other specials. HDTVs have excellent sound as a result of the digital signals present in HDTVs referred to as Dolby Sound. This is beneficial for users as the sound quality is enhanced and refined which is ideal as most CDs and movies are created using this particular sound.
HDTV transmits more than six times the information resulting in an enormous improvement in sound and quality. HD programming and films will be presented in 16:9 wide-screen format. The colors will generally look more realistic due to their greater bandwidth. Through using a HDTV, users can watch numerous programs on one channel. They can also check the program guide while watching a show and change subtitles. HD’s greater clarity means the picture on screen can be less blurred and less fuzzy. Recently, prices have decreased for HDTV-ready TV sets, and most likely will continue to decrease. The question of whether you should get high definition television (HDTV) or Plasma TV will depend on your budget and television needs.
