Ah, but originally I was a Communications Engineer, so I had to learn maths to do with QAM. Thus given time and money I could make a modem, or Digital TV transmitter or receiver (for s, t or c).
An LCD panel or OLED panel is easier in terms of theory. LCD needs very flat glass, thin tin plating, a funky organic liquid, polariser and spacing so accurate that they developed special glass balls to go in the "glue" on the panel edges. OLED aren't real LEDs, but screenprinted or inkjet sprayed organic* electroluminescent chemicals with phosphor coating. Harder. Real LED panels are simplest if you use RGB 4 pin LEDs and make it the size of a billboard. Sony had a real LED monitor about $10,000 which makes OLED look poor.

I don't exactly know enough about Mirasol, but would seem to be amenable to the technique of a DLP chip (nano mirrors) if you wanted a projector. DLP needs a fabrication lab. I did some student experience in one, once. We have some near here, Analog Devices, where I have two relatives working. Though real Engineers and there years, they are not allowed into Fab.
