What Is A DLP & Laser Projector?

A DLP projector is a projector that is using the DLP technology which is short for Digital Light Processing. This technology is developed by Texas Instruments which is used to project images from a monitor to a large screen for presentation or for movies. The way a DLP projector works is by creating an image using microscopic mirrors laid out in a matrix on a semiconductor chip that is known as Digital Micromirror Device (DMD). These mirrors reposition rapidly so it can reflect light through the lenses or onto a heatsink. These chips can process and decode a bit-streamed image code as it enters the semiconductor at a rapid rate and adjusting everything from the contrast to brightness as needed. The craziest part is all of this is done in sixteen microseconds. The DLP projector can also produce close to 35 trillion colors due to its three-chip system.

Laser Projectors are projectors that use laser technology which was once considered science fiction. More of the projectors being made nowadays have started using laser-based technology for several different reasons. Such as efficiency, heat, color, size, and even lifespan. Laser projectors work the same way as any other application does.

Pros & Cons of Laser & DLP Projectors

One of the biggest advantages of a laser projector is they last much longer than a lamp or DLP based projectors. For example, most Laser projectors can last for over thirty to forty thousand hours meaning if you use the project for eight hours a day it should be able to last you approximately ten to fifteen years before you need to buy another one. The benefit is the laser projector tends to be much cooler when running compared to a DLP projector. This is because there are so many moving parts the DLP projector needs to keep everything cool and because of that it can get very noisy. Another advantage is unlike DLP projectors there is no need to wait for the projector to boot up and get bright, it is instantaneous since it is laser-powered. Laser projectors also tend to be much brighter and vibrant compared to DLP projectors. A disadvantage of the laser projectors is it can be significantly more expensive compared to a DLP projector (Possibly double or even triple the amount). The other disadvantage of the laser projector compared to the DLP projector is if you need to replace the projector you have to replace the entire thing not just the laser itself, whereas, with the DLP you can replace the bulb itself as needed.

Final Thoughts & Recommendations

If we were recommending or advising someone to get a projector, we would tell them to look into a laser projector. Yes, there are some cons due to expensiveness, however, we feel in the long run you would end up saving money. Think about it, if you had to replace your bulb every year or every two years on a DLP projector that’s five to ten bulbs in ten years and each bulb can run about two hundred plus dollars meaning in the span of ten years you could spend anywhere from $1,000 to $2,000 or even more based on how expensive the bulbs are. In that same respect if you get a $2,000 projector that lasts you 10+ years you won’t need to worry about replacing anything till the end of the life of the projector. One other thing we would recommend is making sure you get a projector that is short-throw capable. What that means is you can set the projector a few inches away from the wall and project a large image onto the screen/wall instead of needing to mount a projector to the ceiling or put it on the other side of the room to get a big image. Nowadays, you can find short-throw projectors that can project up to 150+ inches from only 10-15 centimeters from the wall. Not only will the save time and space from drilling and mounting TVs but it can also be something that can easily be moved around from one location to another and you can have a TV as big as your wall.
