Digital Signs Services

The Vendor is required to provide digital signs services to remove and replace led panel display (digital display sign) that meets or exceeds the performance of the current.
- Existing digital display sign
• Brand: Samsung
• Screen dimensions: 4.5’ x 7’ 7.5” x 8” per side
• Power:
• Ul listed
• 6.26 regular operating amps
• 21.6 “boot up” amps
• 110vac
• Led load (@ .077w/pix): 2,208w per face
• Total connected load: 2,376w per face
• Input voltage: 120v
• Input configuration: 2-20 cct per face
• Communication type: secure wireless Ethernet bridge
• Cooling: top mounted fans, lower front ventilation
- Guidelines for new digital display sign
• Should fit existing power and dimensions with minimal overlap or border
• Pitch: 10mm (p10) minimum, 8mm (p8) ideal
• Leds: smd 3-in-1 rgb, common cathode, matte black face, 1/8 scan minimum (1/6 or ¼ preferred), 70%-80% drive current at max brightness, anti-corrosion treatment, coated PCBs
• Brightness: 6,500 nits or higher (higher for sunny days-7,000:1 or better, ideal)
• Auto brightness adjustment
• Contrast: 3,000:1 or higher (the higher the better, in general)
• Viewing angle: minimum 140 degrees horizontal, 160 would be better, might allow west bound traffic to see the sign better. 120% vertical
• Color depth: 16-bit
• Refresh rate: 3,840 or higher (cuts flicker)
• Environmental protection: ip65 minimum, ip67 better
• Safe temp range: -40f – 140f or broader
• 5+ year color stability guarantee
• 120 mph wind resistance
• Power consumption: less than or equal to the current sign, 92%-94% driver power consumption efficiency
• Communication: secure wireless Ethernet bridge to match current
• Preference will be given to vendors who offer to include an appropriate, outdoor rated underground line.
• Aluminum cabinet with UV coating.
