A critical development was the blue LED. Background article, "True Boo-Roo":

As far back as the 1950s, even before the first practical LEDs were produced, scientists understood that if a semiconductor diode could be made to produce usable quantities of visible light, then they would have a kind of ideal lamp. In terms of conversion efficiency, of economic use of power, of longevity, and of size and weight, such a lamp would be to conventional tungsten lamps what the transistor was to vacuum tubes.

That is the vision. Well-put by Mr. Johnstone.
