Certified payroll documentation shall be submitted with final application for payment at completion of the projectSpecification Requirements for Outdoor LED Display Panels 1. Scope and Intent This specification outlines the minimum requirements for a full-color, outdoor-rated LED video display panel intended to be integration into an existing monument sign structure. The primary objective is to ensure high visibility, superior image quality, and robust performance in extreme outdoor conditions, while meeting specific dimensional and pixel density targets. The project will require the replacement and integration of both the east and west facing display panels. 2. General Performance Requirements a. Viewable Area Nominally shall be 14' - 0" High x 28' - 0" Wide. The final dimension shall be within +/- 2 inches of nominal but must fit within the prescriptive monument sign box. b. Maximum Power Consumption To be calculated based on pitch, but not to exceed 120W/sq. ft. (typical). Vendor to provide comprehensive electrical load calculations. c. Operating Lifespan 100,000 hours minimum. After which luminous output degrades to 50% of initial level. d. Service Access Front or Rear Serviceable is required for ease of maintenance and minimized sign disruption. e. Color Depth 16-bit processing minimum. Required for smooth color transitions and video performance. f. Refresh Rate 3,840 Hz minimum. Required to prevent flicker on camera and for superior motion handling. g. Display Panel manufacture must have 15 years in the LED industry producing display panels. Panel manufacture shall be capable of sourcing replacement LED modules for a period of 10 years following the final completion date of this installation. 3. Display and Pixel Specifications a. Resolution and Pixel Pitch are critical for content ratio and viewing distance. The physical size and target pixel count are vital requirements. i. Pixel Resolution (Height) 250 Pixels is the minimum requirement ii. Pixel Resolution (Width) 865 Pixels is the maximum requirement iii. Overall Pixel Count Height >= 250 and Width <=865. Final count depends on vendor's selected resolution and module configuration. iv. Effective Pixel Pitch Range 12mm to 16mm (Square). Vendor must select a standard square pitch (12mm, 15mm, 16mm) that meets the required resolution within the specified physical dimensions. (Note: Achieving 865W in 28' requires an effective pitch of approximately 9.85mm. The Vendor shall detail how the W resolution is achieved if a 12mm + pitch is used.) v. Minimum Horizontal Viewing Angle 140 degree. Off-axis uniformity is critical. b. Brightness (Luminance) i. Required Luminance Range (Outdoor) for readability in direct sunlight 10,000 to 12,000 NITS ii. Luminance Control is required for ambient light adjustment and energy savings. Should be automatic 256-level sensor control c. Components i. LED Type should be DIP or SMD (Preference for high-brightness, high-reliability BlackBody SMD). Must be fully encapsulated in front and back of the module. Includes protective coating (conformal coating/gasket) against environmental ingress. ii. LED Manufacturers: Nichia, Cree, or equivalent Tier 1 manufacturer. Required for consistency and lifespan. iii. Contrast Ratio should be 3000:1 minimum. Required for clear visibility of dark content during daytime. 4. Environmental and Physical Requirements The display must be engineered to withstand continuous outdoor exposure, including harsh weather, temperature fluctuations, and UV exposure. a. Ingress Protection (Front/Display Face) IP65 minimum for protection against dust and highpressure water jets. b.
