It has been my experience that LCDs do not emit much energy in themselves
but their
driving electronics might. I just tested a thin film transistor liquid
crystal display on Tuesday.

hello Group:
My question is kind of general but i would appreciate any input /
experience.
typical, TFT-LCD is enclosed in a metal enclosure and there is a shielded
window to prevent any emi from front. Is LCD (video signal) big source of
emi? if LCD unit not properly isolated (shielded) within a system, does it
immune to emi (intra-system interference)?
thank you in advance.
