Rear Screen Projection Screen TVs – Different Types Of Projection TVs

The cheapest type of TV you can buy for the size is a projector based TV. These types of TVs are larger than plasma or LCD TVs and usually sit on the floor or a special type of stand. They are also usually about 1 or 2 feet in thickness and pretty hefty in weight. One other downside is that projection TVs require the bulb inside them to be changed periodically. The interval at which the lights need to be changed differs with each make and model of TV and also varies in price. Some last for a few thousand hours and cost under $100. Others may last tens of thousands of hours and cost a few hundred dollars. But they provide a very large screen area for the price so if you want the absolute biggest TV you can buy and still get a very clear and crisp picture. Projection TVs use a very bright light that shines against a screen to display the TV image. The difference in the many types of projector TVs is how they produce an image for the light to be shone through. There are a few different types of projection based TVs on the market today. There is a standard type of projection TV called LCD projection; this is the oldest type of projection technology that you can buy, but also the cheapest. These usually have basic features but all projection TVs on the market today are HD so they still provide a pretty good picture for the price. They use a small LCD screen similar to the screen on a laptop computer or a cell phone or even large LCD TVs. However this LCD screen is only a few inches big but the pixels are extremely small so when a light is projected through it, the image displays onto the screen of the TV for you to see.

Another type of projector TV is called DLP, which stands for Digital Light Projection. This type uses a small microchip with over a million tiny little mirrors on it that reflect the light either towards the screen or away from it. Similar to LCD projection TVs, a small but very bright light shines towards the small silicon chip to project images onto the screen. With standard DLP projector TVs, the light first goes through what is called a color wheel. This is a small wheel with at least 3 different panels for each of the primary colors: red, green, and blue. This wheel spins at least 90 times each second, allowing every color of the rainbow to be reproduced. However one major drawback to this is that the motor for the color wheel often goes out and needs to be replaced, which can sometimes be a costly repair. Some newer DLP TVs allow the wheel to be changed easily, but usually this is not the case and needs to be changed by a professional.

An improvement on DLP TVs is called 3DLP and instead of a color wheel to produce the different colors, it uses 3 different DLP chips with one for each primary color. This allows smoother moving images and totally gets rid of the problem of the color wheel burning out. 3DLP TVs are often the most expensive of all projection based TVs, but they provide the brightest and clearest picture of all projection based TVs.

As with all types of TVs, the more the TV costs, the more features it usually packs, meaning that a basic projector TV will usually have a few connections for various devices such as cable box and video game console, etc. But the more a TV costs, the more connections and other features it will have. This means that it will you can connect more devices and support pretty much any type of connection you have. So if you have multiple video game consoles, a cable box, DVD player, Blu-Ray player, and want to be able to hook up your laptop or computer then you may want to get a TV that has more connections for more devices. Also make sure that it has all necessary connectors for the equipment that you will want to connect. So if you want to be able to plug in your old VCR as well as multiple High Definition devices through HDMI then make sure the TV will allow you to do so. More expensive models also contain more high tech features, such as 3D TV which lets you watch shows and movies in 3D with special glasses, and internet connectivity and streaming which allows you to do things like stream videos from online services like YouTube, Netflix, and Hulu. Internet connected TVs can also do things like check and update your Twitter or Facebook feeds or even show you the current weather and future weather forecasts. If these things are important to you then you should go ahead and get a slightly higher end model that will have everything that you want. Because TVs are a large investment that you will not want to have to replace in a year or two just because the latest and greatest TVs have all the cool features that you skimped on to save a little bit of money. But it all depends on you and your own needs and wants as well as your budget so take everything into consideration before you go shopping and pick out which TV to buy.
