Wouldn’t doubt it. They generage ubelievable amounts of broadband noise. If you figure out how to suppress it I would love to know how. From what I can tell it’s mainly coming from the lines that connect the FPGA to the SRAM. There is a very large spike at 375 MHz and harmonics all the way up through microwave. One spike is right at 1545 MHz (GPS).
If you download one of the GPS apps to your phone that show the dots where the satellites are and lay the phone on the back side of a running display you can watch them all go out of view and the phone loses GPS lock.
Hi, I did some lab emc testing on the LCD (fitted to a product) and found a lot of noise, but I see another mention to add a 470 uf Electro on the LCD power and Gnd,
.
as said not tested that yet, but will soon as need to retest another product ,
may be worth a try… cant hurt anyway. (unless you scare the cat by putting the wrong way.)
