VIEWING ANGLE
__________________
Diodes can put out a single, narrow beam of light like a flashlight, or they can output a wide array across a room like a light bulb. Diodes output about the same amount of light no matter what type they are - but the “high-beam” diodes with a narrow angle focus more light into one small spot, whereas the “wide angle” diodes spread their light across the horizon. So, if you were to stand in front of a sign made from “high-beam” diodes with narrow viewing angles, you would see an extremely bright sign if you stood directly in front of it, but the minute you walked away from the small spot light of its focus, you would see nothing but black.
With wide viewing angle LEDs, the image is visible in consistent brightness and uniform colors throughout the entire viewing range of the display. Optec Digital Billboards only uses wide angle 1400 LEDs to maximize audience exposure, maintain the highest color accuracy and extend reading times. Maintaining brightness across a wide spectrum also requires greater light output, which is why Optec Digital Billboards uses a higher LED diode density than any other manufacturer in the industry.
