For every 50 feet of viewing distance,
you need a 1-inch character height.

Say your outdoor sign comes into view of traffic at 300 feet. You will need to display a 6-inch or larger character.

You can figure it this way:

300 feet (your sign comes into view)
÷50 feet (per 1-inch character)
--------------------------------------------------
Totals 6 inch characters

If you were in a vehicle going 30 mph,
you would need a minimum of a 4-inch
character height at a 200 feet viewing
distance for your outdoor sign.

Your viewing time can be affected by obstructions,
traffic speed, character size and character style.

The chart on the right will give you an idea of your
viewing time or try the formula below.

Viewing Time Formula

1. Feet in a Mile X Travel Speed = Feet Traveled in an Hour
   5280 feet/mile X 30 mph = 158,400 feet
   
   
2. Feet Traveled in an Hour ÷ Number of Minutes in One Hour = Feet Traveled per Minute
   158,400 feet ÷ 60 minutes/hour = 2640 minutes
   
   
3. Minutes Traveled ÷ Number of Seconds in One Minute = Feet Traveled per Second
   2640 minutes ÷ 60 seconds/minutes = 44 feet
   
   
4. Viewing Distance in Feet ÷ Feet per Second = Number of Seconds to View Display
   200 feet ÷ 44 feet = 4.5 seconds

Provides more detail than standard solid color displays.

Smart Pixels™ can best be explained by
thinking in terms of a 'dot of light'.

These dots are made of a cluster of Light-Emitting Diodes (LEDs) to make a single pixel or light.

Spectrum's Smart Pixels™ come in a cluster of 2 to 5 LEDs per pixels in either RGB full color, Red or Amber.

How are Pixels used to determine the size
of an Electronic LED Display?

If you needed an 8032 display, you are actually saying you need:

Now, if your pixel cluster has 5 LEDs per pixel, then your pixel density is actually:

Formula:

The total number of LEDs per pixel X the number of LEDs per square meter = the total LED Density.

High density electronic displays create sharper images.

The value or cost of your display is determined by the density or number of LEDs. The higher the number of LEDs, the more value you add.

Advantages of having more LEDs per pixel:

• Whiter White
• Less Pixelation
• Better Contrast
• Truer colors
• Longer Life

Horizon™ Electronic LED Displays have a very high LED density when compared to most other manufacturers.

Resolution is how clear your message displays.

To determine your resolution, you need to know the size of your electronic sign cabinet and number of pixels.

See "What is a Smart Pixel™?" question above to figure your total number of pixels.

Next, you need to know the Pitch, or distance between the pixel centers.

See "What does the pitch have to do with electronic displays?" question below.

Pitch is the distance (usually in millimeters) between pixels.

Our electronic displays are bright enough to be seen in any given light condition, while at the same time, not so bright that it blinds people.

The brightness of full color animation screens are measured in NITs because each pixel uses several different colored LEDs of varying brightness.

NIT is a method of measuring the brightness of a surface area which means that it gives a true measurement of impact and also allows comparison to other display types, such as: plasmas, computer monitors, incandescent bulbs, etc.

The actual definition of NIT is candelas (not milliCandelas) per square meter.

Spectrum's Horizon Electronic
Message Displays cut through direct
sunlight using up to 11000 NITs.

An important subject related to brightness is contrast ratio.

This is defined as the ratio between the brightness of an electronic display when lit and un-lit. The higher the contrast ratio, the better the display. The main factor that affects the contrast ratio is natural light reflecting off both the electronic display fascia and the actual LEDs themselves.

Horizon™ Electronic Displays enhance the contrast with:

• sun visors over individual pixels
• fascias coated with diffuser
• LEDs / boards angled slightly downwards
• LED boards treated with a proprietary matt surface

Formula to Figure Your Active Area

Based on a 20mm, 112x32 pixel display

First: Convert inches to mm (1" = 25.4 mm)

Next: To figure Width X Height = Active Area

Total active area = 7.35 feet wide X 2.09 feet height
