What You Should Know About Projectors—DLP vs LCD vs LED

As technology advanced, projectors became more and more easily available and budget friendly. What was once used in cinemas can now accommodate classrooms, corporate meetings or even home cinemas. However, as with any purchase, it is important to know of a few factors before venturing out to buy a new projector. There is a wide variety of them on the market, but maybe some would be better suited to your needs than others, as there is no “one size fits all” and each projector comes equipped with different features that you may or may not need.

After you figured out a few things in order to make a confident buy, such as your budget, the room size, the kind of lighting the room has, and what extra features you might want the projectors to have, then it’s time to delve deeper and understand some technicalities when it comes to the gadgets. In addition, if you’re looking to get a projector only for a short amount of time or you have a single project that you need it for, then instead of buying one maybe renting a projector would be better for you. Projectors are available to rent, such as those offered by Hartford Rentals.

Nowadays, projectors come in three types: LCD, LED and DLP, each coming with different advantages. Back in the day, CRT projectors were common, but they were bulky and had low light output, among other issues, and are no longer commonly used. The technology that projectors use can be either transmissive or reflective. A DLP projector has mirrors in order to direct the light in an image, thus it is considered to be reflective. On the other hand, LCD projectors are passing light through the panels, as opposed to bouncing it away, and are considered to be a transmissive medium. Lastly, LED projectors are named for the light source, and not for the type of technology they use.

The technology that LCD projectors use is more reliable and established than film projectors. They have no moving parts (as opposed to DLP projectors) and are generally more budget friendly. They support setups in large rooms where a bigger projection distance might be needed, as they are compatible with lens shifts and zoom lenses. Thus, LCD projectors are suited for home cinema projects.

DLP Projectors need less maintenance than LCD, as they have a sealed and filter-free chip design, meaning that dust won’t settle on it and it won’t cause an image spot. In addition, the projectors are virtually immune to color decay. They are not subject to misalignment, which is something that can occur in LCD projects that have a three-panel design.

The LEDs within an LED projector have a longer life-span that traditional projector lamps, lasting up to 10 or even 20,000 hours, compared to the 1 to 5,000 hours. This can be an advantage in multimedia setups, as replacing lamps can be quite an expense. They are energy efficient and don’t need to warm-up or cool-down, and they are also much quieter.
