If you are planning to buy a projector, then you must be seeing so many options such as Gaming, Office, High Performance, Value, Premium, Education, Next Gen etc. Basically there are only 3 technologies widely used for the making of consumer projectors. They are LED, LCD and DLP. Just imagine our TV technologies LED, LCD, Plasma and CRT etc. Then the question is can't we use the LED TV for education purpose? Or can't we use the LCD TV for office purpose? We can use any technology or any type of projectors for any purpose. Same logic applies on projector as well. There are few specially designed for certain purpose. Say for example, a gaming TV. What does it mean? A gaming TV is a normal TV with the a little higher picture refresh rate than other consumer TVs. This doesn't mean that a gaming TV cannot be used for any other purposes or any other type of TV cannot be used for gaming purpose. The same applies for the projectors as well. Just know little more about LED, LCD and DLP. Then jump into your projector selection leaving other marketing techniques away.
Also, although the chip is sealed, other components are not, so dust can settle on the color wheel and affect image quality. Another disadvantage may be the poor viewing range. Most DLP projectors are not readily compatible with zoom lenses or lens shift functions, which means they are best suited to smaller environments. This would likely not be the best choice for a large home theater projector.
DLP, LCD, and LED Technology
The technology used in projectors can generally be broken down into two types: transmissive or reflective. Because LCD projectors pass light through the LCD panels rather than bouncing it away, they are considered a transmissive medium. A DLP projector uses mirrors to direct the light in an image, so it is considered to be reflective.The third type of projector discussed, an LED projector, is named for the light source, not the type of projection technology.How DLP Projectors Work
DLP projectors first appeared on the market in the 1980s, and they rely primarily on a DLP chip (called a digital micromirror device, or DMD), comprised of up to 2 million tiny mirrors, no wider than one-fifth the width of a human hair. Each mirror in this chip is capable of independent adjustment, moving toward or away from the light source to create a dark or light pixel. At this point, however, the image is in grayscale. Color is fed to the DMD by a beam of light that passes through a spinning color wheel before it reaches the chip. Each segment of the color wheel delivers one color. Basic color wheels support red, blue, and green, whereas more advanced color wheels support cyan, magenta, and yellow. While these chips can create up to 16.7 million colors, a DLP projector with a three-chip architecture can deliver up to 35 trillion colors. After color reaches the DMD, the image is fed through the lens and onto the projection screen.Advantages and Disadvantages to DLP Projectors
DLP projectors require less maintenance than LCD projectors because they have a filter-free and sealed chip design, which means dust cannot settle on the chip and cause an image spot. They are effectively immune to color decay. Furthermore, they are not subject to the misalignments that can occur in LCD projectors with a three-panel design, which require each panel to be in perfect position to combine the image at the proper angle. However, DLP projectors with slower color wheels may give off a rainbow effect, which is when bright flashes of color appear on the screen, like rainbows.Also, although the chip is sealed, other components are not, so dust can settle on the color wheel and affect image quality. Another disadvantage may be the poor viewing range. Most DLP projectors are not readily compatible with zoom lenses or lens shift functions, which means they are best suited to smaller environments. This would likely not be the best choice for a large home theater projector.
