How to Compare LCD and DLP Projection TVs

LCD and DLP are two common types of HD televisions.

There are many choices when it comes to high-definition television. Plasma, LCD, DLP and LED all have their strengths and weaknesses. Knowing the differences between these televisions and how they work will allow you to choose the HD TV that is right for you.

DLP

Digital light processing or DLP televisions are a new technology created by Texas Instruments. These are more common in educational and business settings. DLP works by sending your signal to a microchip that houses tiny mirrors. The mirrors then in return project the signal onto your television's screen. This results in a clear, crisp picture full of detail. DLP televisions produce more heat and use more electricity than LCD televisions.

LCD

Liquid crystal displays use two sheets of polarizing material such as glass. A liquid crystal solution is then injected between the two sheets of glass. LCD then electrically charges this solution so that light can either pass through them or the light is blocked, the result is your picture. LCD televisions produce little to no heat and can save you money on your electric bill.

Television Maintenance

Research the type of maintenance your DLP or LCD television require. Usually the LCD television will last longer than the DLP television because there are less parts that make it work. The DLP televison utilizes an optical engine that may need to be replaced over time. The cost of these engines can be expensive. The LCD television does not have a lot of extra parts that need to be replaced.
