For many consumers these days, HD TVs are the popular choice. Short for high-definition television, they use digital signals instead of the usual analog ones. They were first introduced in the market back during 1990′s later parts. Since then they have changed the way people enjoy home viewing.
The images you see on the display panel carry a resolution of 1920 x 1080 pixels. With this resolution, everything you see boasts of up to twice the clarity of images displayed on a CRT counterpart. Also, the screen aspect ratio or the length-to-height ratio is equivalent to 16:1 instead of the usual 4:3. Such is superb for widescreen movie viewing.
In choosing one for your home, there are plenty of things to consider. So many of them are available in the market today, all seemingly alike; getting the right one for your needs can prove to be a tricky task. However, not all of them are cut from the same fabric. One of the first few things you have to decide on is picking the type of display panel. Currently, the two most popular types are LCD and plasma.
LCD stands for liquid crystal display. Basically, there are liquid crystals sandwiched between two glass panes, making the images. Then a backlighting source, often LED of CCFL, illuminates the images formed. In contrast, plasma utilizes gases trapped within tiny glass cells. When an electric current passes through them, the image is formed on the screen.
Both LCD and plasma come with their own set of advantages and disadvantages. An LCD unit consumes energy more efficiently, is suitable for use even in brightly-lit rooms, and is lighter so it’s superb for wall mounting. But it’s susceptible to motion blurs and judders. A plasma unit is usually cheaper, offers better contrast, and yields sharper images. However, it emits more heat and is prone to glare on its screen.
Other than the display used, they share some of the other technologies which you may want to consider. For instance, ask the sales personnel about how many HDMI (high definition multimedia interface) a unit offers. This will allow you to come up with your ideal entertainment system at home easily, connecting your favorite HD components.
In choosing one from among HD TVs today, it’s important that you know exactly what you want. There are models which come with innovations like TV-based web browsing, 3D viewing, video calling and others. All of these features show up in the unit’s price tag.
