Integrated Systems Europe (ISE) 2025, held in Barcelona, Spain, recently concluded. ISE brings corporate giants and emerging stars together across technology categories, including audio, broadcast, lighting, and communication. It also showcased commercial display systems that competed for attendees’ attention with a wider variety of sizes, enhanced performance, and a more appealing cost of ownership.
Electronic Paper
Electronic paper (e-paper) is an eye-friendly reflective display technology that strives to mimic the visual qualities of a printed page, including excellent readability outdoors or in brightly lit environments. The pixel technology of an e-paper display can require several seconds to update, making it better suited for static imagery – think e-reader devices like the Amazon Kindle or digital signage applications. However, once an e-paper display establishes an image, little to no additional power is required to maintain its appearance. These highly efficient display devices can be front-lit for increased readability in darkened environments, and some smaller e-paper screens offer up to 300 PPI resolution.

One challenge for e-paper display designs has been increasing screen size beyond handheld devices or something akin to a smaller computer monitor. On display (pun intended) at ISE 2025 was the largest e-paper display yet offered by E Ink, which pioneered many of the most popular e-paper technologies. The 75-inch display is part of the company’s Kaleido 3 series and was demonstrated in prototype products on the show floor at several company booths, including Agile Display Solutions, DynaScan, LG Electronics, and Samsung Electronics.

The extreme energy efficiency of e-paper displays had me excited to see Agile Display Solutions earn some ISE best-of-show nods for its upcoming 32-inch Forever Display (EPD32-FD) featuring E Ink’s Spectra 6 color display module. The Forever Display is designed with a solar panel array along the top edge of its aluminum frame, allowing it to recharge its lithium-ion battery using standard store lighting. Equipped with an ARM processor, 16GB of storage, and Wi-Fi connectivity, the EPD32-FD can be set up quickly without cables or additional maintenance. Forever Display owners can adjust content programming and apply updates through a dedicated mobile app (available on iOS and Android) or a cloud service website.

Direct View LED
Direct-view LED (DVLED) displays dominate the commercial display industry with their impressive brightness, vibrant colors, and near-perfect picture contrast. Each DVLED display consists of smaller modules that house arrays of individual LEDs. These modules simplify installation and maintenance, offering large-format options that can be scaled to nearly any size while maintaining durability for indoor and outdoor applications.
Samsung’s ISE 2025 booth attracted crowds who admired a large-scale demonstration of the company’s The Wall micro-LED display technology. Visitors gazed at a “media facade” that combined a 462-inch screen configuration of The Wall (IWC series) with smoke machines and projectors, extending the presentation beyond the pixels and into the surrounding floor space. Another demonstration of The Wall at the booth showed it operating as the centerpiece of a command and control room. These Samsung DVLED products featured a 1.26mm pixel pitch, 1000 nits of brightness, and 95% coverage of the DCI-P3 color space. Additional pixel pitch options for The Wall IWC series include 0.8mm and 1.6mm spacing options.

The Philips booth at ISE showcased the company’s latest additions to its L-Line series of DVLED display modules, introducing a new outdoor signage line named Urban LED. The 7000, 6000, and 5000 series modules have IP66/65 (front/rear) ratings and can operate in temperature ranges from -30 to 50°C. These modules provide various size and pixel performance options for creating vibrant outdoor signage, featuring impressive LED lifetime specifications of 100,000 hours to half brightness.
The Urban LED 6000 series boasts an impressive 10000 nits of peak brightness, ensuring its images remain well-defined even in direct sunlight. Available cabinet sizes include 1200x1200mm, 800x1200mm, and 800x900mm panels, with pixel pitch options of 6.67mm, 8.33mm, and 10.0mm – optimized for viewing distances from 10 to 30 meters. With a display refresh rate of 7680Hz, the 6000 series provides artifact-free imagery when captured by the latest professional broadcast cameras – an essential feature for digital signage in sports arenas or environments that regularly capture digital video. With similar pixel pitch options and peak brightness as the 6000 series, the Urban LED 5000 series will offer additional panel size options of 1600x900mm and 2000x900mm.

The Urban LED 7000 series offers a peak brightness of up to 6000 nits and finer pixel pitch options of 2.9mm, 3.9mm, and 4.8mm, making for more seamless viewing at closer distances than the 5000 or 6000 series. The cabinet size options for the 7000 series include 500x500mm and 500x1000mm, which are also better suited for space-constrained applications.

Hybrid Projection
Laser phosphor light engines for video projectors are not a new concept. The first laser projector utilized a two-color laser system to excite phosphor material, creating RGB (red, green, and blue) for a full-color image. The projection specialists at Christie Digital introduced a new product at ISE 2025, tailored for professional installations that demand efficient and dependable bright imagery with broad video format support. The Christie Sapphire 4K40-RGBH showcases the company’s first high-bright design, which integrates a “…hybrid RGB pure laser and laser phosphor…” into the light engine. This engine can achieve the DCI-P3 color gamut at up to a claimed 36400 ANSI lumens (depending on the lens option). For operation at 100% brightness, Sapphire’s self-contained liquid cooling system facilitates a 25000-hour to half-brightness rating with its RGB laser light source and 20000 hours for the laser phosphor light source.
Christie Sapphire 4K40-RGBH hybrid laser phosphor projector
Sapphire’s dust-sealed 3-chip DLP (1.38-inch DMDs) pixel engine delivers 4096 x 2160 resolution and supports all active and passive 3D formats. The projector is compatible with every screen type, including rear projection and gain-enhancing designs, and its 202.8-pound (92kg) chassis can be mounted and operated in any desired orientation. The Sapphire’s extensive video connection options include DisplayPort, HDMI, and Quad 12G-SDI. Sapphire’s video output includes 4K at 60Hz imaging, and high frame rate options are available for up to 4K120 or 2K480.
With its dual laser phosphor system, Sapphire’s hybrid light engine enables efficient light output at a lower price than generating the same amount of light using RGB lasers alone. The projector’s phosphor illumination can also be blended with the laser output to minimize common artifacts like laser speckle. While Christie’s RGB laser-only projector designs can achieve color gamut coverage approaching the all-encompassing BT.2020 standard, Sapphire’s solid coverage of DCI-P3 makes it well-suited for accurately representing most video content.
Commercial Benefits
ISE 2025 showcased today’s visually stunning display technologies and their capacity to transform public spaces and business environments with customized messaging, data visualization, and artistic flair. Although many of these technologies may not be entirely suitable for residential use, they inspire imagination and fuel innovation for consumer products that offer similar efficiencies, functionality, and longevity.
