Live events, one of the verticals hit hard during the pandemic, are starting to see people come back. A lot of people. As COVID-19 restrictions continue to be lifted, guests and attendees are excited to be back in their element, whether it is a house of worship, music festival, or conference.
The resurgence in attendance at these large venues is clear. And now, integrators are looking to new, innovative ways to enhance that experience.
“Integrators and technology professionals are turning toward large-venue projectors to create engaging displays," said Ramzi Shakra, product manager, Epson America. "While this includes concerts and live events, we’re also seeing a lot of interest in theater production, corporate events and spaces, across school campuses, and tradeshows and conventions.”
“As we’ve seen with the popular 'Van Gogh: The Immersive Experience' exhibition—which has drawn in millions of global visitors—large venues, such as museums, are adopting technologies to create larger-than-life digital experiences and experiential events to attract consumers,” added Brian Soto, director of product management, Optoma Technology.

The larger the venue, the more oomph is required from the projector. At the same time, projectors need to be nearly invisible—a quiet, unobtrusive piece of equipment that keeps the focus on the content. That’s why manufacturers continue to design more compact and lightweight projectors, creating flexibility and easier setup.
“The weight and dimension for large- venue projectors have been considerably reduced over the last decade,” explained Soto. “In the past, a 10,000-lumen projector easily weighed 50-60 pounds without a lens. Today, however, high-lumen projectors on the market weigh far less, even with a lens, and offer a much smaller footprint.”
The Great LCD/DLP Debate
Most venues are looking for very high brightness levels that manage a diverse range of content. Over the years, one of the larger considerations in projectors, especially when looking to maintain the same quality with higher lumens, was whether to go LCD or DLP.
“Both LCD and DLP offer their advantages,” explained Sander Phipps, senior solutions engineer, Sony Electronics. “Three-chip DLPs are well suited for high-brightness applications above 20,000 lumens, while LCD offers an excellent visual performance at an economical price point for applications with lesser brightness needs.”

Making the case for DLP projectors, Soto offered several advantages. “Since DLP technology is based on reflective mirrors rather than an organic material (liquid crystal display), its image quality does not degrade over time,” he explained. “DLP also minimizes the ‘screen door’ effect when producing images, whereas LCD has space between the liquid crystal pixels, so users can more readily see that spacing. Additionally, DLP technology allows a compact architecture for virtually maintenance-free designs, requiring no filters and, for laser projectors, no lamp replacements.”
Conversely, Shakra feels LCD, specifically the 3LCD technology that Epson uses, may provide more advantages. “The 3LCD three-chip architecture dedicates an entire chip to process each primary color continuously, resulting in vibrant, realistic content with true-to-life color and equal brightness," he noted. "While available on premium higher lumen projectors with three-chip technology, the majority of DLP projectors use single-chip technology that delivers color sequentially.”
So, the debate has not only shifted to consider LCD or DLP, but which chip technology is best. According to Soto, one-chip technology leverages one color wheel for color performance, so it is more affordable and compact, but others feel that three-chip technology is more advantageous in today’s market.
“One-chip projectors are, to an extent, a design compromise,” Phipps said. “They can be made smaller and less expensive, but at the sacrifice of picture quality. 3LCD offers picture quality at a one-chip cost.”
In today’s world of entertainment and services—one which relies on dynamic visuals that try to provide immersive environments for consumers—there are more factors to look for when selecting the right projector for the job.
“Important considerations for large-venue projectors include flexibility of use—for instance, large lens shift ranges and a full set of lens options,” Phipps explained. “These allow flexibility in placement. Additionally, low maintenance designs like filter-less or self-cleaning filter systems are beneficial. Typically, large-venue projectors may not be easily accessible.”
"The compatible, interchangeable lens family should cover the full range, from ultra-short-throw to long-throw with minimal gaps," Shakra added. "Ensuring compatibility and consistency across projector platforms and different chassis will help with efficiency and cost savings over the long term for end users.”
Let’s not forget about edge blending. Large, high-quality images are easier to create with dvLED displays and video walls, but the process is a little trickier with projectors. For a seamless image, multiple projectors must align perfectly to overlap in the respective regions for content, brightness, and detail.
“Edge blending technology has advanced over the years, with projector manufacturers introducing new tools and software that are built directly into a projector’s interface to help automate edge-blending and create a seamless image from multiple projectors,” Soto said. “With these new features, integrators have more control over image alignment with the help of guided displays and built-in cameras, for example, ensuring images are weaved seamlessly together with ease.”

With those advances and added control in projector technology, has edge blending become as easy as one-touch technology?
“A touch of a single button may be a bit of an oversimplification," Shakra said. "However, with advanced tools available today, we have been able to reduce the complexity and time required to create a large, blended image with multiple projectors. Epson’s automated tools take care of the alignment between the projectors’ overlapping image as well as the gradation in brightness in the blended area to ensure there is no hot spot, creating a seamless, ultra-large, and stunning display to impress audiences.”
“One key here is that the projector needs the ability to project deep blacks and have an accurate gamma response,” Phipps added. “With this, the blend zone will be very smooth and minimize the 'bright stripe' so often seen when projectors are blended.”
Lamps or Laser?
Simply put, projectors, especially for larger venues, have changed. There are more use cases and higher lumens needed than ever before. Chances are that large-venue projectors are being used more frequently and longer during performances or events.
Which makes the lamp projector a dying breed.
“Laser projectors are preferred for numerous reasons, including the ability to lower your overall total cost of ownership,” Phipps explained. “With laser projection, there’s no costly, inconvenient, or dangerous lamps to replace, as laser systems usually run much cooler. They also provide a light source that allows the projector imager to last longer. And, with instant on/off features, users no longer wait for lamps to warm up or cool off. Time is money.”

“There is no denying that laser technology in projectors is on the rise,” Shakra agreed. “When choosing lamp or laser, there isn't a specific feature set to look for per se—it really depends on the application of the projector. Pending the exact application and setting for the projectors, a few things worth looking for are brightness level, size, weight, and fan noise.”
