Popular Television Terms
Television technology is advancing faster now more than ever. With many end of the year sales happening soon, now is a great time to purchase a new model. Here are some popular terms regarding these devices.
Rear Projection – This type of technology uses a picture that is created from a video signal and, using a bright beam of light, magnifies it onto the display. This system is wholly contained inside the device and is only found in big sets. These were very popular and, up until the mid 2000s, used in many homes. They still offer a very cost effective alternative to newer model liquid crystal displays.
HDTV – HDTVs have video resolution that is much clearer and higher than ordinary devices. Compared to standard displays, it has five times the pixels per frame.
LCD – This is a type of flat screen or electronic visual display that consists of liquid crystals. The liquid crystals use light modulating properties, though they do not emit light directly. They have replaced cathode ray tube displays in things like video players and telephones, and are used frequently in televisions. They are more efficient and use less power than traditional methods, making them a perfect option for bigger devices.
Plasma – This is a type of display common in large sets. Electronically charged ionized gases are utilized in this type of technology. Essentially, these are tiny fluorescent lamps inside tiny chambers. The picture quality is very clear.
Panel – These devices can be as thin as 3 inches and are a very popular option with many households. Most modern models come designed this way because they are lighter and thinner than traditional models.
New and used televisions are sold in various stores across America, as well as online. Ever since the first TV was invented back in 1923, these unique electronic devices have been supplying the world with daily entertainment. Televisions continue to improve with bigger screens, higher resolution pictures, better audio, and more digital channels. Today there are HD or high definition TVs, as well as televisions with LED screens, which provide images using light emitting diodes.
With so many new and used TVs on the market today, things can get confusing if you are not up to date on HDTV features, plasma screens, projection devices, and satellite signal connection options. There are wide panel LCD TVs now, which offer liquid crystal display for a better picture. While some people use satellite service to get various channels, others take advantage of cable. Regardless, there are plenty of sales on HDTVs that mount on the wall, small portable units, and televisions that use less energy to assist the environment. Many people buy flat panel TVs these days for the excellent image resolution, and small amount of space they take up. Many big screen LCD TVs can be purchased at great value, and some even offer 3D or three dimensional picture features.
By getting in touch with your local electronics store or supercenter, you can get more information on new and used televisions. In fact, this is a great way to get all of the answers you need to questions about satellite connections, flat panel units, and wide screen TVs.
