A little 'history
Texas Instruments engineer, Dr. Larry Hornbeck was the primary inventor of the Digital Micro-Mirror Device (DMD). The further development of this 1987-1993 until he brought about his present condition as Digital Light Processing (DLP) chip set for what is best known as TV Rear Projection TV and DLP design known. Currently, the world's largest manufacturer of projection DLP TV Mitsubishi Electric, which include specialistsArea of the large TV screen.
How DLP televisions work
A rear-projection TV uses a set of over a million microscopic mirrors (DMD) is to be measured individually by 0.02 mm wide. The DMD is individually controlled by a hinge and spatial light modulator and semiconductor optical devices. When the digital processor chip of the light it receives a digital video or graphic signal input, is transformed into a light black and white video signal. The light signal is then passed through theProjection lens is enhanced by the projection lamp and then synchronized with the rotating color filter wheel. The pictures are on the back of the screen, which is seen as opposed to projects outside.
Advantages and disadvantages of DLP TV
DLP rear projection TVs have a fairly loyal customer base with most, they say, are a great TV would do. Given the image quality, sharpness, clarity and screen refresh rateSize value for the money, many would agree. But the DLP during their time not without drawbacks, which unfortunately is forcing an indelible impression of him criticism among his peers, seems to lose its place among the shelves of most television and electronics stores around the world are been abandoned.
Some of these disadvantages are:
After a blown lamp dimming or replaced every few years is probably one of the biggest knock again. However, it is a TV projection, and their bulbs finally burnlike any other video-projector lamp. Another thing that would be the average punter does not deter a true successor is airy glow that the DLP with the constant switching of the lamp within the housing enclosure of the DLP TV have. This problem is similar to that used for backlighting LCD TV with traditional backlighting. Produces a lower contrast ratio, where the colors true blacks are not blacks in dark scenes, but very dark blue-violetNuances. Then there is their physical footprint, which is usually attributed to the fact that they are unique in television, moving mechanical parts, may require a size appropriate to the mass of the chassis in the house. While they are relatively light weight compared to a plasma screen TV or LCD with a similar, but take a piece lot of space on the floor.
Value for Money
At the price, is a new 73-inch Mitsubishi 1080p DLP HD-Ready 3D TV for just over $ 1,200. During a 60-inch 1080p LGPlasma HDTV is priced at $ 1300 + price. Put it next to a Samsung 60-inch 1080p LED / LCD HDTV will bring you back only a couple of dollars just $ 2,500, which is more than double the price of the DLP TV in the even smaller screen size. Mitsubishi rear projection TV series usually the screen size of 65 inches, 73 inches and 82 inches, and not break the bank either. But before you rush to the door and buy a DLP TV, you have the cost of maintaining one. Replacing the projection lamp 2or it can mount three times during the life of a new rear projection TV to more than a few hundred dollars. Of course, the lamp life depends on what the TV settings in terms of "brightness", "Saturation" and "Contrast" and for how long and how often you set up on a daily basis. In essence, the key to a longer-lasting light "all the settings in moderation."
Any words last piece of advice if you are considering buying a DLP rearTelevision projection would be to read on a second opinion and go see one for you, check it out and then make your opinion. However, if you are already with the Mitsubishi DLP set, and nothing against it with its little quirks you are interested and excited about the Laser TV to know. A new generation of completely revised and updated DLP TV that uses laser technology as the main source of light in a few stepsQuality in the class of big screen HD TV.
