How do LED display boards work?

Complex integrated electronic circuits and software send pulsating electronic signals to each LED and when activated, they illuminate the individual LED (light emitting diode) lamp.  Each LED lamp (pixel) is built up in a matrix, thus making up the length and height of the illuminated LED display boards.

The resolution of the display is determined by how many pixels are in the matrix.  When the LED display boards is programmed and turned on, each pixel can illuminate independently and appear to 'glide' along the LED display board panel.  In reality, it is a case of each pixel (LED lamp) being charged with electricity in an on-off fashion.

For example, if pixel A sits next to pixel B and is alternatively turned on-off it would appear as if the dot moves.  This is how our scrolling LED display boards work.
