3. The matrix panel shall consist of three-color options: Red, Green, and

Amber (Yellow).

4. The Amber (Yellow) color shall be achieved by turning on the Red and

Green LEDs in sequence.

5. The matrix panel background shall be black.

6. Each display pixel shall be comprise of Red (660 nm dominate

wavelength) and Green (565 nm dominate wavelength) LEDs within a

single chip.

7. LED pixel size shall maintain a consistent diameter of 0.2 inches or

0.05 centimeters

8. LED pixel spacing is required to maintain a minimum center-to-center

spacing of 0.3 inches (0.8 centimeters) for 2.1-inch character height.

9. The LEDs shall maintain intensity greater than 80% for a minimum of

three years.

10. All LED chips shall have a minimum of 120-degree (180 degree

preferred) horizontal (x-axis) viewing angle in low ambient light

conditions and/or 35 degrees in sunlight conditions.

11. Pixels shall be constructed with chip-type (surface mount) LEDs. Chip-

type (surface mount) LEDs shall conform to the following

specifications:

i LEDs shall be high-bright, 70 mcd minimum, solid-state light

emitting diodes for in-door applications.

ii LED use in direct sunlight conditions requires ultra-bright, 300 mcd

minimum, and solid-state light emitting diodes for in-door

applications.

iii LEDs of the same color shall be from the same manufacturer and

of the same part number.

iv Maximum LED wavelength variance shall be +/- 2 nanometers

(nm).

v LED half-life shall be a minimum of 100,000 hours of continuous

use.

vi Letter of certification from the LED manufacturer is required for

proper testing and binning according to International Commission

on Illumination (CIE 127 (1997) standards).

B. LED Module:

1. The failure of a single pixel shall not cause the failure of any other pixel

in the display.
