Graphical LED Displays
Graphical LED displays employ a state of the art technology to broadcast
high-resolution graphics and video. Nearly any type of data feed can be
connected to these displays. For this reason, you will see these
impressive electronic signs towering over the streets of the world's great
cosmopolitan cities.
While some of the bigger displays feature characters over six feet tall
and whose length measures over 100 feet tall, there are smaller sizes to
fit any budget. These displays come in one, two, or multiple-line
displays. They also come in variable colors, and the most common include
red, green, yellow, or a tri-color version of all three.
Graphical LED displays also come in blue and white. Interestingly though,
white has proved the most difficult color to produce under LED technology.
LED stands for light-emitting diodes, and is considered the most efficient
form of lighting today. . They don't get hot when in use, which is why
they are called a "cold-light technology."
LEDs don't burn off heat as a wasted byproduct like incandescent lighting.
Instead, graphical LED displays convert all the energy they use in
electricity into light. It thus comes as no surprise to see LED lighting
supplant other more conventional forms of lighting in some of the world's
most impressive outdoor signs.
