LVX displays show live and recorded video clips, real-time scores/stats, animations, graphics, and text messages. Modules feature SMD (3-in-1) LED packages with 10 mm row and column spacing. 2.03 Display A. General information 1. Cabinet Dimensions: 19.69' (6.00 m) high, 36.00' (10.97 m) wide, 11.0625" (281 mm) deep 2. Matrix size: 600 x 1080 3. Weight: 7200 lb (3266 kg) 4. Power requirements: 43509 W 5. Ad panel width: 0.28 (0.09 m) @2 – not offered with logo/sponsor graphics B. Cabinet Paint Color 1. Standard: Semi-gloss black on sides only C. Construction 1. All-aluminum construction for light weight and corrosion resistance 2. Service Access: Front or Rear D. Display Capabilities 1. Color Capacity: 16 bit (281 trillion colors) 2. LED Refresh Rate: 4800 Hz as defined by the number of times per second the LED image is repainted in intensity 3. Display has signal redundancy allowing for signal path both forward and backwards through modules allowing for loss of only 1 module vs. rows or blocks of multiple modules or panels in case of failure. E. Viewing Characteristics 1. Module Intensity: 8000 nits (adjustable) 2. Brightness Control: 256 levels (manual, scheduled or automatic) 3. Suggested Viewing Angle: 160° horizontal and +10°/-65° vertical F. Pixel Characteristics 1. Each pixel consists of one RGB 3-in-1 surface-mount device LED. 2. Pixel spacing measurement must be measured from the center points of neighboring physical pixels, rather than neighboring physical and virtual pixels. G. LED Module Characteristics 1. Module shall be for outdoor use. 2. Module shall have anti-reflective paint or coating applied to display face. Black state across all modules shall exhibit a Delta E color variation of no more than .4. 3. Modules shall have horizontal louvers running between LEDs or pixels. 4. Modules shall be able to be removed and installed from both the front and rear of the display. 5. It is not necessary to remove or insert screws to remove or install modules. 6. Module shall be silicon potted on face beneath louver and rear, providing a 100% waterproof seal, regardless of module, cabinet or panel construction. H. Video Processing 1. Video Frame Rate: 50/60 frames per second 2. Graphic Frame Rate: 30 frames per second 3. Processing Architecture: 22-bit distributed 4. System Architecture: 100% digital 5. Video Enhancement: Color space conversion, adjustable gamma correction, proprietary sharpening technology and enhancement algorithms for optimal picture quality I. LED Quality 1. Quality Control: Sorted by intensity and color wavelength 2. LED Lifetime: 100,000 hours of operation as defined by time at which display intensity has decreased to 50 percent of the original intensity J. Calibration 1. Pixel-to-pixel and module-to-module optical color calibration must be performed at the factory. The manufacturer must also provide easy-to-use calibration software that allows individual modules and pixels to be independently adjusted while in the display. 2. If modules should need replacement during the life of the display, the calibration software must match newer modules’ brightness levels to older modules’ levels to preserve picture quality and maintain a uniform display appearance. K. Display Interface 1. The full-color video display must be able to interface and display real-time data from the control system without the need for a duplicate or redundant input.
