Plasma TVs have bright colours, rapid update rates, and lots of contrast. It’s possible that plasma TVs are what catch your eye as you walk down the lane at Best Buy. Plasma TVs have colours that are very clear, bright, and vivid. But, like most beneficial things in life, there is a negative side to think about. Plasma televisions use a lot of power and don’t last very long. However, you may buy a better, more high-tech TV in the future. To be sure, many, if not most, middle-class American homes feel more important when they have the newest TV technology. If all you wanted was a television, you could have bought a nice-looking older CRT TV at Wal-Mart or Costco for a very reasonable price. Some tests have shown that in the first four weeks, a plasma screen’s ability to show true black drops by 13%.
Over a few years, this could make blacks look like light greys in your picture. If you’re willing to pay a slightly higher electricity bill, you might not mind that it consumes a significant amount of power. However, the real issue, similar to laptops, lies in the significant amount of heat it generates and the potential damage it can cause to electronics, including your high-priced plasma TV screen. Millions of tiny light tubes stacked on top of a heavy glass base create the picture. This is where the heat comes from. This shape also contributes to the short lifespan of the display. The small area generates a lot of heat, causing the phosphors to burn out faster than on a regular CRT.
This can also cause picture burn-in to tie everything together, especially on channels that keep their name in the bottom right spot. LCD TVs are a lot less expensive than plasma TVs, but the pictures on them aren’t always as clear or bright. One major problem with LCD screens is that the pixels take a while to change states. Smooth-moving things like a hockey puck or baseball bat might look better on a plasma or high-quality CRT, but they get hazy on LCD screens. A projection TV is another option. The pictures on projection TVs are now much clearer and brighter than they used to be, and the black levels are deeper than on CRT TVs and better than on most plasma and LCD TVs.
For screens 50 inches or bigger, this is the way to go. The bulb that emits bright light during the day is the major problem with all projector technologies. A lot of the metal-halide projector lamps have a lifespan of only 1000 to 2000 hours per hour, necessitating replacement at a cost of several hundred dollars. Ultra-high-performance (UHP) lights with longer life spans have just hit the market. They use mercury vapour instead of argon, and they last between 3,000 and 10,000 hours. A lot of people watch TV every year—about 1,000 hours on average. If the bulb costs between $300 and $500, it will cost a few hundred dollars a year to run the projection TV for about 1,000 hours per bulb. We usually guess how long a bulb will last based on perfect conditions, not real-life situations where the homeowner might accidentally block heat flow because of the TV or the wife’s preference for looks over durability.
From an abstract point of view, it looks like the company that makes projection TVs offers lights that are very specific to their products. I understand that no other company or organisation produces or sells projection TV lights as well as a reputable company like Sony. Truth be told, there might be a cheaper light available, such as one from Hitachi. Having said that, the choice ultimately comes down to personal preference. Sony lights are more popular and easier to find on eBay, despite their higher cost. But fragile projection TV bulbs may not make it through the mail. Companies are switching to high-intensity LED technology to replace lamps. These LEDs will last for years, just like LCD screens. That tech isn’t cheap, but as more people get access to it over the next few years, prices should go down. We can look forward to SESEDs, the next big thing in high-tech TVs. What does SED mean? Surface-conduction electron-emitter display (SENDS) is an acronym.
By the end of 2007, Japan is likely to start seeing them. They are flat-panel displays, like LCD screens today, but their brightness and picture quality are more similar to those of CRT screens. The system’s construction essentially functions as a miniature CRT for each image. It consumes less power than plasma because it is easier to make an electron beam (like a CRT) than to get photons excited in a gas (like a plasma display). Currently, there is no display in production for SED TVs. No information is available about other efficiency or dependability factors. Finally, have fun with your You could buy a plasma TV now, pay it off, and then admit that you really liked it. Then you could buy a newer SED TV for your home, which has a better picture and is a sign of wealth.
