Such displays are made up of number of LEDs. There may be single colour (mostly RED) or multi colour LEDs and there are very nice text animation effects like appearing-disappearing text, left-right scrolling, top-bottom scrolling etc. But have you seen such animation effects on text LCD?  It is possible to give such text animation effects on LCD also.
