There are so many types of manufacturers of projectors and slide projectors to choose from, choose one seems to be an impossible task is correct, but it did not happen. With a little 'research, a little known, and with the help of this whole article, you know what you're buying a slide projector is right for you trust.
Most projectors currently on the market today, one of two main features of LCD and DLP projection technology. Representative of the liquid crystal display liquid crystal is the oldest and most widely used projection technology. In this type of projector, LCD projector 3 is separated into a spectrum of colors of red, green, blue, and through these groups in the past form the image on the screen.
With LCD technology, usually have better color saturation, that is, the color is more active, more clearly. These images and data re usually more than one, rather than a DLP projector and LCD in detail, but it should be noted that the DLP display technology is a relatively new technology, constantly improving and updating the requirements.
Representative digital light processing projection, is a relatively new technology, which reflects the small projector lamp spinning mirror, and through the color wheel, producing the image displayed on the screen, thousands of light. DLP display technology is a patented technology developed by Texas Instruments.
With DLP technology, there are fewer pixels are generally available, the projection of video projection, which is the reason many home theater enthusiasts prefer a LCD projector to make a better choice. DLP technology is also capable of producing more than the average high-contrast LCD projector. The contrast is used to describe the video black on black measuring the level of terminology.
A major weakness was observed with DLP technology, the tendency to produce the color wheel projector is commonly known as the rainbow effect on this as a product of the screen. Not everyone, however, this effect can be seen, and as technology improved and now, six sub-series color wheel DLP projector, this problem is gradually reduced.
To replace the silicon-based liquid crystal on silicon is a very high resolution, the prices generally higher, on average, compared to LCD and DLP projector of the type of product. LCOS projector using three liquid crystal on silicon chip, a modulated red, green and blue channels. There is no color wheel, no rainbow effect or due to high E. coli Island visible pixels SXGA 1365×1024 resolution or higher grade.
The disadvantage is that the technology LCOS, low contrast, lamp life is limited, but if you need the highest resolution, that this type of projector can be the right choice for you.
Now, your headlamps existing technologies for different types of knowledge, the next step is to determine the use of your projector needs.
