1.3 Product Overview
The Daktronics DistaView LED scoreboards are part of a family of scoring and
timing displays designed to offer easy installation, readability and reliability.
Microprocessor control assures consistent operation and accuracy.
Featuring large, highly visible DistaView digits, the boards use light emitting diodes,
or LEDs, to illuminate the display. LEDs are tiny, solid-state components that use a
semiconductor chip to transform electrical current into light; they are high-intensity,
low-energy lighting units. Scoreboards in this series only use red LEDs for optimum
outdoor readability.
Because of their LED technology, the scoreboards consume little power – barely
more than a single household lamp. Power usage for displays in this series equals
100 watts.
