You might remember your teachers using projectors to illustrate diagrams or write math equations back in high school. But today, projectors are used for so much more than that. The technology has advanced rapidly, and projectors are frequently used in audio-visual (AV) setups for corporate gatherings ranging from trade shows and product launches to shareholder and sales meetings.
Projectors work by projecting visual content from input sources onto larger screens. They’ve become indispensable tools for putting on corporate events, turning any venue into a dynamic visual experience.
In this article, we answer the question: how does a projector work? We’ll also compare three leading projection technologies—DLP, LCD, and LED—highlighting how each transforms source data into larger-than-life visuals.
Projectors use light to magnify and cast visual signals from a laptop, media player, or other input source onto a surface like a screen or wall. They’re frequently used in large venue presentations, projection mapping for corporate events, hybrid meetings, and digital signage.
Let’s take a look at the internal components of projection technology.
At the core of projector technology is a high-powered lamp that shines a bright white light. This light passes through filtering elements to create vivid images or video content.
Projectors use either DLP or LCD chip technology to process a source signal and transform light into visual images. These chips use millions of microscopic mirrors (DLP) or liquid crystal shutters (LCD) to control the light pixel-by-pixel.
A projection lens gathers newly created image beams and projects an expanded image onto a screen or wall. This lens can be adjusted to alter the image size or sharpen the focus.
Projectors can transform white light into vibrant, colorful images via a spinning color wheel. This wheel filters white light into red, green and blue flashes that perfectly synchronize with the imaging system.
Working in tandem, these components allow modern projectors to transform tiny electrical signals into dynamic big-screen visuals at major corporate and entertainment events.
There are three main technologies used in modern projectors, and each creates images in a unique way, providing specific benefits:
Let’s take a look at each of these technologies and their applications.
Crisp, Dynamic Visuals
A DLP chip displays images by reflecting light through the projector lens via an array of microscopic mirrors, with each mirror representing an individual pixel. Popular DLP projector brands include Optoma, ViewSonic and BenQ.
Vibrant Colors, Ideal for Static Displays
LCD projectors create images by shining light through liquid crystal panels. Each pixel in the panel acts as a shutter, either blocking light or allowing it to pass through. Popular brands include Epson, NEC and Panasonic.
Compact, Energy-efficient Design
LED projectors differ from traditional DLP and LCD models in that they use light-emitting diodes as their light source. But LED technology can be paired with either DLP or LCD technology to create image and video projections.
When selecting projectors for your event, you should take into account a variety of factors, including the type of corporate event, your goals and vision, the venue, and your other AV equipment.
Larger venues like ballrooms and arenas require a higher level of brightness to process images clearly and be visible to your audience. A high-brightness LCD projector with at least 4,000 lumens is ideal.
The lighting in your venue space can also affect brightness requirements. An outdoor venue or a large ballroom with ambient lighting will require a brighter projector to ensure image quality, while a low-lumen LED projector will typically work well in a dark breakroom.
Traditional projectors are most effective on smooth, even surfaces such as walls and screens. Projecting onto irregular surfaces usually results in significant image distortion. However, 3D Projection mapping software can process input in real time and digitally adjust images and video to fit the intended surface. This allows you to display fast-moving visuals onto buildings, landscapes, and even water.
Throw distance refers to how far the projector is from the projection surface. Choosing the best projector for your event depends on the throw distance as it relates to the size of your image.
Simply divide the throw distance by the width of the image to determine the ideal throw ratio for your projector. For example, if your throw distance is 20 feet and your image is 10 feet wide, you would need a projector with a throw ratio of 2:1 to ensure the best possible quality.
Small, lightweight projectors that are easy to set up are essential for mobile events. LED projectors tend to be lighter and more portable, making them ideal for pop-ups and meeting rooms.
Consider the scale of your event and the variability of your needs. Does your projector need to integrate with a complex AV system, or can it work effectively through a single source?
There are two main options when it comes to connectivity and control:
Lasers represent the cutting-edge in projection technology. They’re poised to become the new benchmark for image quality and versatility across applications, including AV event production.
These innovative devices use laser diodes, rather than traditional lamps, to generate light. These diodes emit colorful beams of red, green, and blue laser light through a DLP or LCD imaging system. Chips modulate these laser beams pixel by pixel, and the projection lens casts vibrant, sharp images onto a larger display.
Key advantages of laser projectors include:
Laser models currently cost more than lamp-based devices, but their unparalleled performance makes them the undisputed future of projection technology when it comes to demanding applications like museum exhibits, medical imaging, simulation systems, and more. As costs decline, lasers will become the gold standard for both home and professional AV setups.
When choosing a projector, it's crucial to consider the specific needs of your environment:
