Designed to provide high-quality video images in an outdoor, high-ambient-light environment, the TF-16BK module from Barco uses a flat black matrix background for high-contrast output and 16mm pixel pitch to deliver fine detail with a three-black-lamp LED configuration. Each tile is 60"x60" with a density of 3600 LEDs, producing a typical calibrated brightness of 6000 nits and a contrast ratio of 7000:1. The unit has 16-bit color processing and a 110-degree horizontal viewing angle to 50 percent brightness. It also features an 800Hz refresh rate and maximum power consumption of 400W with an average consumption of 120W. The tile is 37.8in. square, weighs 106lbs., and has a rated operating life of 100,000 hours. This is a vital specification on such equipment due to the high ticket investment made in these display systems. Each TF-16 tile is rain-rated (IP65 front, IP54 back) with clickable shaders, and each has an operating range spec of -31 degrees to 122 degrees Fahrenheit with a choice for maintenance access from the front or rear. The tiles can be mounted in flat, convex, or concave shaped frames to suit existing architecture.
For a small-footprint, lightweight-module design, D3 LED (Dynamic Digital Displays) offers the TrueElement Gigabit Ethernet-based outdoor LED display module with 16-bit color processing, diagnostic features, and diode level color calibration provided by its Windows-based control system. Each 14.9in.-square tile weighs less than 20lbs. and is weather-sealed by two vacuum-molded rear cover panels. Each unit has its own temperature-sensing, forced-air cooling with auto-high-temp shutoff, a data distribution system, and onboard memory. When one module is substituted for another, the replacement automatically imports its address and calibration data from those around it through the bottom-mounted RJ-45 port. Each module is installed into a steel frame by way of a spring-loaded four-point latching system with adjustment pins, allowing access from front or rear using no special tools. The TrueElement Smart Module is designed with a recessed area on the bottom that includes connection ports for power, data, and ventilator. Pixel pitch availability ranges from 8mm to 24mm, and the TrueElement Front End Video System accepts high-def signals including uncompressed HD-SDI, HDMI, and Blu-ray.
Daktronics fields a wide variety of LED signage products including indoor/outdoor tile modules and ribbon board displays. Among the outdoor LED display modules offered is the DVX line with sealed inputs and outputs along with a louvered face to increase contrast in high ambient light and mask the seams between panels. The DVX products range in pixel pitch from 10mm, with a minimum viewing distance of 22ft., to the 26mm module, with a minimum viewing distance of 59ft. The smaller 10mm and 12mm resolution modules use three-in-one SMD pixels providing a viewing angle of 140 degrees horizontal and 75 degrees vertical. The larger-pitch modules use discrete red, green, and blue LEDs. The modules use adaptive cabinet mounting for a range of available display shapes and allow LED-level (sub-pixel) processing for smooth motion and sharp lines. The displays are rated at 100,000 hours, and system health monitoring is done through Intelligent Device Management (IDM). The Venus 7000 display controller can be used for video, fascia, and message center displays, and with its Quick Display feature, it can launch synchronized presentations with background audio. A calibration feature allows newer, brighter LED modules to be matched to older ones to avoid a patchwork appearance.
One of the newest and most advanced integrated LED video displays has been provided by Lighthouse Jumbovision for the Bradley Center, home of the NBA's Milwaukee Bucks. Designed by Anthony James Partners and integrated by TS Sports, the Bradley Center's new center-hung video board features more than 1,000 square feet of Lighthouse Pi6-S 6mm-pitch LED video distributed across four main screens, plus 300 linear feet of Lighthouse Pi10-FA 10mm-pitch entertainment strips encircling both the top and bottom of the center-hung videoboard. In addition to a scoring matrix and four LED video corner wedges that feature the home team's logo, the center-hung videoboard boasts a world's first underside LED video display featuring a Lighthouse P16i/o (16mm) screen, which is capable of displaying video, logos, and animations. The Bradley Center's one-of-a-kind center-hung video display features more than 2,500 square feet and nearly 3.5 million pixels of LED video. The new video system is 29ft. tall and 32 ft. wide, and it weighs approximately 50,000lbs. One of the most beneficial aspects of the all-LED video system is its versatility. In addition to the Bucks, the Bradley Center hosts Milwaukee Admirals hockey, Marquette University basketball, and Milwaukee Iron arena football. The new scoreboard can be customized to provide a true home court or field for each team.
