[Elecraft] LED vs LCD PC Monitor: RFI?

[Bruce Beford]

"LED" monitors are still LCDs. they just use LEDs for the backlight, instead
of fluorescent lamp. In general the LCD monitors are "quieter" than the CRT
type. I have not heard of any data indicating that LED backlights for LCDs
are RFi-quieter that CCFLs. (cold cathode fluorescent) as a breed.

 

it will be interesting to see if anyone can indicate an RFI problem from an
LCD that was resolved by replacing with an LED-backlit model/. Still, that
would not be definative. Simple differences in other parts of the
design/construction may be a factor. Still, the LED does not need a
high-voltage supply- that is a design point in it's favor.

 

The primary advantages of the newer LED backlights are longer life (the LED
does not lose its brightness over time), and reduction of hazardous
substances (notably, mercury in the CCFLs)
