Is my friend's display on my HP Spectre X360 Convertible 15-eb0043dx LED, or OLED?

Hello - I have a friend who is remote and I would like to repair his screen. How do I know if this laptop has a LED, or OLED display? I have the serial number, but HP's website doesn't provide the type of display associated with his laptop. Any help would very much be appreciated. Thank you. He sent me a snapshot of his laptop info: 15 - EB0043DHP X360 15.6 IN ULTRA HD TOUCH-SCREEN L.

FROM HP SPECS: 15.6" diagonal 4K UHD, IPS, micro-edge, WLED-backlit, multitouch-enabled, edge-to-edge glass with anti-reflection Corning® Gorilla® Glass NBT™, 340 nits, 72% NTSC (3840 x 2160)

Thank you!

I wish HP simply stated that it was an LED.  From the link you provided it shows LCD, but also does show WLED. Of the three types of displays listed within the link you provided, the nits from the bottom description match the HP specs for the HP model I am referring to, so this must be the one, but, again, how do you know this is an LED?

@supercell 

LED or WLED (White LED) is not a panel itself, but a backlighting technology for LCD monitors, one of the differences is that the WLEDs are bright immediately and the LEDs take a few seconds longer.

Ok. So it's actually a WLED(?)

Yes,this is what is used in high-end laptop displays usually.
