admin — Sun, 21 Sep 2008 23:59:18 +0000

LCD TV screens do not have a problem with high altitudes. These are all made with similar specifications, which mean no LCD TV is better than the other one, disregarding the brand names.

LCD technology is able to produce screen sizes up to 37 inches. However, larger sizes are still in study along with making the LCD technology better.

LCD TV’s are lighter so the LCD TV wall mount bracket does not have to support as much weight.

LCD TV screens are not prone to burn in. There might be a few “ghosting” occurrences, but no picture burn in. A ghosting is the retaining of the images in a shadowy form, which is different from burn in which is the picture retaining down to pixels. However, LCD TV screens are prone to have satellite and cable signals related problems. LCD TVs do have many universal flat screen tv wall mounts.

LCD technology has contrast ratio lower than the plasma technology.

LCD technology has a problem with the pixels of their screens. When one pixel is used up, it will be noticed in the screen with missing areas of black and white. This is one huge disadvantage as when missing pixels becomes noticeable, one will need to replace his or her whole screen.

These are also lighter and less expensive.
They do not reflect too much light, which makes them great even in a well-lit room. They are also not as prone to overheat as plasma.

DLP technology also has its own advantages and disadvantages.

DLP TV screens are much expensive compared to LCD or plasma.

DLP technology can also produce the best picture quality. It is able to provide high-definition television with its fine resolution. These require less maintenance.

However, the screen is prone to rainbow effects.

DLP technology does not also cover a wide range of viewing angle.

Not everyone knows the differences of Plasma, DLP and LCD TV screens. After all, all of these are flat screen displays. There are pros cons of LCD, Plasma, DLP, technologies of flat TV screens that are needed to be weighed against each other to know which one is best suited to one’s wants in a flat panel screen. We will also look at the difference between flat panel tv wall mounts and lcd tv mounts.

The following are the advantages and drawbacks of plasma TVs.

•    Automatic pixel shift technology is used in plasma TV screens. This technology prevents damages due to burn in, which occur and has a high possibility when a picture stays on the screen for a period of time.
•    Plasma TV screens have an advantage in their color management that allowed these flat screens to be available in larger sizes that other flat screen technologies cannot render. Also, plasma TV screens also have the ability to create better contrast and deeper blacks. As such, customization of color management comes in more options to address the different preferences of people.
•    Plasma TVs are more prone to overheat, and thus have higher risks of having dysfunctional problems in display, especially when there are sudden changes in temperature. As such, some plasma TVs are made to be compatible with high altitudes, but these are more expensive.
•    To maximize that appreciation of the technology, plasma screens are usually available in 32 inches to 63 inches. With its ability to support wider angle of viewing, plasma TVs are also heavier. Because of these, the flat panel wall mount needs a strong wall as a support.

Televisions are very important means of getting enough information of important events from all over the world. This piece of entertainment technology also made it possible for people to enjoy life in a new way. As change is inevitable, people did not stop with what we used to have generations ago.
Not long after, flat panel screens were born. Nowadays, there are plasma, LCD, and DLP TV screens. While a lot of thing about them differ in many ways, there are common things about them. As for example, the brands themselves hold a certain difference, not only in the impact and credibility of the brand names but also to the features that were made limited to these brands. Another example is the add-ons provided to their products. The following are the general information about LCD, plasma, DLP TVs, and also the regular CRT televisions.
•    Picture Quality. Each of the flat panel screens includes a high contrast ratio. However, the range also differs according to the technology. Plasma televisions have the highest contrast ratio. The proof for this is the ability of this technology to produce larger sizes, almost double of the biggest size of the other flat panel screens.
Brightness is another factor that affects the picture quality of the screen. If the brightness does not conform to the normal visual perception of brightness of a person, that person might eventually have his or her eyes adjust to the brightness capability of the television. Indeed, in short, this also affects the eyesight condition of the person.
•    Viewing Angle. Most flat panels have wide viewing angle range. The wider the viewing angle is, the better, especially for those who have potentially large number of viewers.
•    Motion Response Time. This is also another common among the flat panel screens. Higher motion response time allows the screen to address fast picture changing, thus ghosting and burn in are prevented.
•    Tuner and Connections. It is also common to flat panel screens to have the ability to adapt to the latest technology nowadays.
The above are some of the good points of flat panel TVs. There are also the not so good ones, and below is of these.
•    Flat panels are more prone to overheating compared to the CRTs. Plasma for example is not able to withstand frequent sudden weather changes and high altitudes. This is the reason why there are special plasma televisions intended for high altitudes. While LCD TV screens are not as prone to overheating, it still is when compared to the traditional tube TVs.
Aside from the fact that flat panels are indeed quite expensive, with careful choosing, these can actually last for a long time. While taking care of them depends on the owners, the functionality and usefulness of each television are also factors to the lifetime of a TV.

The popularity of flat screens did a great job in preparing the people to get used to seeing only flat screens being sold. As such, the options of people were also diverted to the beautiful designs of flat screens.

The sales history of flat screens shows a great increase during the first years, and sudden decrease nowadays. This is after the general analysis of sales weight against the demand throughout the years. It was 1936 when the principle of flat television, of plasma technology, was described by Kalman Tihanyi. It was until the 1960s that the plasma technology was better researched.
After this new sleek design, flat panel screen was introduced to the market, the demand for television boomed. While issues regarding the flat designs were first raised as questions, these became the markets of these products. By providing answers to these questions, the advantages of a flat panel TV are realized.
The first decades of flat screens in the market were great, but not smooth.

People who by that time were able to afford the “new” television seemed to have the opportunity to enjoy it. While as for the others who were also shocked with the prices then, they were able to simply accept that something new has come to take over the place of color tube televisions. As at that time, it was also the era when a lot of things seemed to be being replaced by new products of technology. As for example, it was also the decade that cellular phones were introduced to take over the position of land lines and first models of cellular phones.
