What display do I have CCFL or LED? T400 1440x900

I have a T400 with a 1440x900 display (according to device manager).  Unfortunately I scuffed the screen and I would like to repalce it.  My screen has the Matte finish, not glossy.  How do I tell if I have a CCFL or LED screen?  I searched the forum and I don't find any information on how I can tell.  Thanks.

Do you know if this works for a refurbished Laptop as well? Or is it possible that they used a different screen and didn´t change the number?

I happen to be on my old T400 at the moment and my machine has LED back light, CCFL would have faded away years ago

 

Lenovo has used LED for a long time and I have seen DIY for earlier models to retrofit them with LED which does take some amount of work to do

 

The back light is along the bottom edge of the LCD, which has to be swapped, then the controller board has to be changed too, not easy but its been done

 

Considering a T41 is how old, cheaper to buy a newer machine on eBay.

 

I own: T400 T500 X220 X230 all running Windows 10 Professional
