Technically its a LED driver board not an inverter. Inverters are used with CCFL backlights.
The 2011 iMac came with either a four pin version iMac 27" LED Backlight Board V1 (4-Pin) or an eight pin unit iMac 27" LED Backlight Board V2 (8-Pin). To complicate things a bit both use the same P/N 923-0047. You’ll need to inspect what you have before you order the part.
As far as using a 2010 board I wouldn’t.
这个答案有帮助吗？
Hi dan, thank you to clarify.
the lcd board that I have came from a non working iMac 27 mid 2010.
this board has four pin just like the one in the iMac 2011.
it will be Work in that iMac? Is there any risk to test?
thank you to take your time
It's not the same part, see for your self a very different P/N 661-5576 iMac 27" LED Backlight Board
Again, I wouldn't chance it.

@oldturkey03 - Please re-read my posting. There are two versions! The lower NITS display is the four conductor version.
