Consumer Electronic Information: The Basics of the DLP Projector

Consumer Electronic Information: The Basics of the DLP Projector
By Simon Canfield

Projectors have come a long way in the past few decades. The desktop fossils that were once used to show home moviesor classroom filmstrips are a thing of the past. With todays technology, you can now experience a projected movie that emulates a full-blown theater flick, without thetime, effort and hassle of standing in line at the local cinema.

DLP projectors also known as Digital Light Processing projectors have brought the proverbial silver screen to the home front. The fact that some theaters actually use this type of technology for feature movie projection makes this truer than you might imagine. After being digitally converted and placed on an optical disk much in the same way as DVD technology is produced the images are fed intothe projector and sent to the movie screen. The main difference is that DLP projectors offer a high definition experience, as opposed to that of a DVD. The result is a picture that very nearly rivals the quality of a 70mm projection, but without the imperfections.

The color accuracy of the DLP system is outstanding, with an end result that beats LCD technology. Some of the advantages that make a DLP the projector of choice are its low power consumption, compactness, micro-mirror construction (which is responsible for the high level screen resolution), high contrast and brightness. All in all, this is the closest that anyone can come to having a bona fide cinema within the confines of their home.

With every set of pros, youll always find some cons lurking in the shadows. Such is the case with the DLP projector. For those who are particularly sensitive to certain visual effects, the DLP design produces a type of rainbow effect, which could serve as a distraction when looking from one side of the screen to the other during viewing. This will play out as a brief splash of colors, which is simply a result of the type of technology thats used in the production of the DLP. Most people dont even notice this color display, but those who are in tune to that sort of thing may see it as an annoyance.

While this is also true for LCD projectors, consumers mightbe disappointed to know that DLP projectors need to have their light source changed after every 1,000 to 2,000 viewing hours. All in all, though, this is nothing new and, when you consider the higher quality that this type ofsystem offers, it shouldnt be seen as much of an inconvenience at all.

Perhaps the most inhibitive aspect to the acquisition of a home theater system, such as the DLP, is that the cost willtypically fall within the range of $5,000 to $10,000 for the mid-range systems, once you purchase everything that youll need in order to complete the set-up. In addition to that, youll have to consider the cost of the rest of your home theater system, since these figures only factor in the DLP expenses.

For those who can afford to do so, the DLP projector is an excellent investment, despite its few downfalls. While no projection system is perfect, DLP is currently the most popular set-up on the market and provides a powerful theater experience for those who arent inhibited by space or finances.

Home Theater Video Projectors

Home Theater Video Projectors
By Jason Gluckman

A home theater enables us to view films in the comfortable ambience of our homes. The unique ambience of movie halls can be recreated completely, minus the crowds, and favorite movies can be watched with friends and relatives in comfort. Home theater video projectors are the main component around which the home theater system runs.

At present, there are three kinds of video projector technology in use. They are CRT, LCD, and DLP. Apart from these, there are certain modifications also available based on the technology used for the above three.

During the early years of video projectors, television expertise was centered on Cathode Ray Tube technology, or CRT. Cathode ray tubes are used for the generation of a television image. Three small CRTs with a single unit meant for every principal color, and a light-magnifying lens, helps in the projection of a color representation against a big screen in a dimly lit room. A CRT projector is capable of creating superior high-resolution images. This can be achieved with the help of the right combination of video processing circuitry, CRT size, and lens combination.

The second sort of video projector is the LCD projector, or Liquid Crystal Display. This is different from a CRT projector in the sense that it is not based on the conventional projection tube. An LCD projector primarily operates by delivering a strong light source through a transparent LCD chip comprising of individual pixels, which exhibits the moving video image. This image is subsequently projected through a lens to a big screen.

The rapid developing sort of video projector with respect to sales is the DLP, or Digital Light Processing projector. This type of projector is very similar to the LCD as in this also the real image is exhibited on a chip.

Computer Projector Rentals: A Guide

Computer Projector Rentals: A Guide
By Marcus Peterson

Any meeting or conference requires a computer to handle inputs like data, graphics, video and audio. Computer as a multimedia application has properties comparable to standalone players for VCD or DVD. With the integration of IT and the Internet into the audio visual industry, computers have become an indispensable item of equipment. They are a common product line in the inventory of a/v rental companies.

To have a meeting with computer aided presentation of data, graphics and video, one needs to have a projector that is compatible with different makes of computers such as IBM and Mac. For instance, an iMAC computer has different requirements than other systems. The accessories that come with computer projectors are audio and video cables, speakers and screen.

The type of screen is decided by the number of members in the audience. If it is a small gathering, a 27 monitor may be used. For large gatherings, a flat screen display or a plasma monitor with 50 monitor may be used. If it is a notebook computer, the laptop must be activated to have the output to the projector. Depending on the number of the people, importance of brightness, contrast and resolution, an LCD projector would be a good fit for the occasion.

The important factors an event manager must consider before choosing the a/v system are the room size, lighting conditions, the inputs that will be displayed, the resolution and clarity of the visual images and screen size. Depending upon the requirements, the rental rate may vary from $300 to $500. Also, the rental companies provide value added services such as complete solutions to manage the event.

Computer projectors are used by corporate houses and universities for business presentations and seminars. They can be booked by phone or online. Most rental companies deliver the systems the previous day. The major manufacturers of computer projector systems are Hitachi, 3M, Compaq and Canon.
