Televisions are one of the most common electrical appliances found in homes and most people will have at least one available. While other forms of entertainment such as video games, internet and computers have become popular in recent years, most people will still watch television on a daily basis. Television technology has advanced over the years and there are a few different types used these days. This includes a DLP projection TV and these can be commonly found on the market.
DLP technology has been around for more than 20 years now and many of the major electrical manufacturers now produce televisions using the technology. At the heart of the technology is the DLP chip which was first developed in 1980’s by Texas Instruments. The chip contains around 2 million microscopic mirrors and when this is included in a system with a digital signal, a light source and a projection lens, the small mirrors can reflect a digital image onto a screen. Using this technology a DLP projection TV can produce a picture of extremely high definition and quality.
There are a few things to consider when considering a DLP projection TV. There are three different types of light source available. The most commonly used is a mercury vapor halide metal halide lamp. These tend to have a useful lifespan of around 2 years and they will eventually start to deteriorate which will affect the quality of the picture or the TV may stop working altogether. When purchasing this type of DLP TV you will need to factor in the cost of replacing the lamp every so often to ensure that the picture quality is maintained and this can cost around $100 to $200 each time.
Since around 2006 a couple of other light source methods have been developed and these comprise LED-based DLP televisions and Laser-based DLP televisions. Using these eliminates the need to change the lamp and they can also provide a more vibrant on-screen color. They are therefore an option to consider when buying a DLP projection TV.
Most of the major electrical manufacturers produce DLP projection TV models. This includes companies such as Mitsubishi, LG Electronics, Samsung, Philips and JVC. However these are only a few of the many manufacturers that produce televisions using DLP technology and there is a wide selection from which consumers can make a choice. A couple of the DLP televisions that get some of the best reviews include the Mitsubishi WD-65837 which has a 65 inch screen and the Samsung HL56A650 which is a 56 inch screen TV. In terms of cost, this will typically be dependent on the size of the TV. The largest screen sizes of up to 80 inches or greater can cost around $3,000 to purchase although smaller screen sizes of around 40 to 50 inches can be found for around $1,000 or less.
If you are looking for excellent picture quality then a DLP projection TV is one to consider for your home. The technology produces stunning images and with the advent of LED and Laser-based technology this is continuing to improve. It can therefore be a good choice to make when you are in the market for a new television.
