30 lane eDP have varying signal types you need to check the stock panel specs against the new one. The things that need to match exactly are
- panel size
- whether its touch or not
- interface type eg eDP number of pins etc
- shape style (otherwise it might to too thin to too fat)
- signal interface position (if the 30 pin is on the opposite side ur shit outa luck without some ribbon cable hack)
- resolution apparently but this wasn't my experience upgrading an x240 with an x250 1080p IPS panel
That panel is eDP 1.4b and the stock is 1.2 hbr1 I'd wager it won't work.
You could just play it safe and get a stock IPS panel which I do with all my thinkpads.
