A DLP (Digital Light Processing) projector is a step up from the classic lamp model. Most of the digital movies shown in theaters use DLP projectors. These produce images with a color wheel and microscopic mirrors. A “one-chip” DLP uses a single light source, while a 3-chip DLP dedicates one light to each primary color.
A very common illumination technique used with the stereomicroscope is oblique illumination, usually achieved by using two fiber-optic light guides or ...

OLED screens work differently. Each pixel in an OLED (Organic Light Emitting Diode) display produces its own light. This makes it thinner and more power-efficient with better image quality than an LED. The way OLED works means it can’t be used in projectors.
Picture a typical classroom or office space circa 20 years ago. It likely has a lamp projector hung from its ceiling or propped up on a cart. These models use a halogen bulb to create light, which shines through a slide then up through a glass bed.
The downside is simple. Laser projectors currently represent the cutting edge of the field. That makes them relatively expensive. High-end models also tend to be heavy. If you need to travel with a projector, your most convenient options will likely be LED.

DLP projectors originally ran off a single halogen bulb, but are now just as likely to use a laser or LED. To contrast a DLP vs laser projector, the DLP is primarily intended for auditoriums. For typical business applications, a DLP is more than you need — but it could be worth a look for your home theater.

It’s easy to take your projector for granted. It’s a faithful tool for office presentations and video conferences. But advancements in projector technology have come a long way even in just the last few years. They last longer, run cooler, and use less power. All while displaying a sharp and easy-to-read image in a variety of lighting conditions.

When you compare a laser projector vs lamp, it’s a night-and-day difference. A laser projector uses three separate colored lasers. These provide a crisp picture at almost any range and don’t require bulbs or filters. They also don’t need much maintenance and can last for years.
If you put a laser projector vs OLED, head to head, you get a clearer image from an OLED display. Yet projectors’ images are often easier on the eyes, since you don’t have to look right into a light source. For long-term use, a laser projector has an edge for business applications.

The Compact Laser Projector WXL5860 is a great all-around performer. It has the flexibility, long lifespan, and crisp picture to handle a range of applications. It’s bright enough to work almost anywhere, including well-lit spaces. It’s also likely light enough at 10.1 pounds to carry with you. If you’d rather mount your projector on a table or ceiling, it even supports 360-degree installation.
There are also more options to consider and questions to answer than ever before. For example, what are the benefits of a laser projector vs lamp? What’s the difference between an LED, an OLED, and a DLP projector? Let’s go through it step by step so you can decide what you want and how to get it.
The laser projector vs lamp question also comes down to a matter of cost. The lamp projector might save you money up front, but it needs new parts and regular maintenance. In the long term, you will likely save money with a laser projector.
