With so many new innovations in televisions today, it’s hard to keep up with all of the popular technologies. Each of these technologies have advantages and disadvantages. It can be confusing as to what these technologies mean and if you really want or need what they have to offer. There are many people who have a wonderful understanding of all of this, but to the vast majority of us this is almost like mastering a new language. Many of us remember how easy it once was to buy a television. In the past, all you needed to consider was the size of the screen and if you could afford it. Technology has its advantages because the picture and sound quality have advanced dramatically in recent years and continues to advance, along with the addition of numerous new features. This article is the result of quite a bit of research. In this article, I have attempted to put in the most basic terms what these technologies are and how they differ from each other. It is my hope that with this information you will be able to make a better decision about which TV is best for you.
LCD, Plasma and DLP are the most popular technologies behind displaying pictures on HDTV today. Every shopper buying a TV today needs to know what these terms mean in order to make an intelligent decision about the best TV to buy.
What is LCD? LCD stands for Liquid Crystal Display. There is a lot of technical jargon out there that explains the science behind this in very exacting and complicated terms. For the purposes of buying a TV, all you need to know is that LCD is a television display type that uses a viscous liquid and a mesh of transistors to turn pixels on and off. Direct-view and projection television both use this technology and in both, the LCDs require a light to generate brightness.
What are the advantages of LCD TVs?
(1) Low energy consumption. LCD TVs use very low amounts of power.
(2) Cooler running temperature. The light source (fluorescent bulb) in an LCD television generates less heat than a Plasma or traditional television.
(3) Low amounts of glare.
(4) Quality LCDs have excellent brightness level TCL Smart TV pictures and offer more contrast. Compared to Plasma TVs, LCD TVs have an increased image brightness.
(5) LCD flat panels can be mounted on walls and don’t take up much room. They are typically slightly lighter than Plasma TVs.
(6) Fairly long display life. The display life of quality LCDs is approximately 60,000 hours, after which you may only have to replace the light source.
What are the disadvantages of LCD TVs?
(1) LCDs are not good for fast moving images because when objects move quickly across the screen, the image “delays” and has a tail following it on the screen when it shouldn’t. There are two ways to avoid this issue. By purchasing LCDs that are 37″ or smaller you will have a better image quality since the delay is less noticeable than on the larger LCD TVs. Another way is to buy a 120hz LCD, but those models are higher in price than the 60hz models.
(2) LCD reviews indicate that brightness levels aren’t as good as Plasma. Although black levels have improved, they also are still not quite up to the level of Plasma.
(3) The viewing angle of an LCD is not as good as a Plasma. If you are watching an LCD from a slanted view, the quality of the image can diminish. However, this difference between LCD and Plasma is not that significant.
(4) LCD TVs over 35″ are very expensive.
What is Plasma? Sometimes all flat-panel HDTVs are referred to as Plasma screens. This is a misnomer. Plasma screens have more in common with Cathode Ray Tube (CRT) TVs than with LCDs. The plasma gas strikes specific pixels at the front of the TV and the pixel then turns to a specific color. Backlights are not needed with Plasma screens because the plasma varies the intensity of light which then produces a full range of colors which typically have an advantage over LCDs because they have deeper blacks.
What are the advantages of Plasma TVs?
(1) Great life span. Typically, at an average use of six hours per day, they will last about 20 years.
(2) Better viewing angles. Unlike LCDs, a Plasma screen has about 180 degrees field of vision without loss of picture quality, so you can watch from any angle.
