LED susceptibility to ESD?

How susceptible is a LED to ESD; specifically, the backlight LEDs in a
liquid crystal display?

I've taken out drivers and hosed systems, zapping LCDs but never a backlight.
Don't know if there was any latent damage, though. If you're worried, put an
anti-parallel diode across them.

If you are zapping an LED display, you are likely going to fail drive
circuitry before you fry any of the LEDs. As you zap an LED, the driver
circuit for it likely gets worse damage.

Nowhere near as sensitive as diode Lasers. Now, those are sensitive.

Thanks for all the comments.

That is because they get modulated. The gate is what gets fried.

Diode lasers don't have a gate.

Boris, I'd like you to meet the resident SED expert on absolutely nothing,
AlwaysWrong. I don't know what he does other than breathing other people's
air and making a fool of himself on Usenet. As usual.

How do they get switched at 10Gb/s then? Certainly more susceptible
than a simple continuous laser diode for a 'laser pointer'.

I don't know what he does...

You do not know ANYTHING about me, you pathetic, cringing milksop!

I only need to know one thing. That you're AlwaysWrong.

No, but your retarded slut mother was.
