Replacing a Laptop OLED screen with a different IPS one

[kinsi]

Curious if somebody has tried this before, originally this laptop uses a Samsung 4K OLED Panel - That one is broken and a replacement is pretty costly, also I think 4K at this size isnt really necessary to begin with, so my idea is to swap it for a much less costly FHD IPS panel.

 

I've researched the feasability of this quite a bit and generally it seems like it might work, the main issue being that they are wired differently. Unfortunately getting Datasheets / Pinouts to confirm this seems impossible as they are locked behind Panelook but based off publicly accessible Datasheets I've found for similar Panels it seems like I'd just need to rewire the voltage supply pins.

Is there a variant of that laptop that came with an FHD IPS panel? If so you might be able to swap the entire screen assembly.

I dont believe so, the Model is Acer Swift Edge SFE16-42 - I believe all the Swift Edges are OLED

Then chances of it working are basically 0. Even if the connector aligns theres many things that can cause it to just not work.

If I just plugged it in as is that would definitely be the case and would probably blow up, but even if I rewire the pins to where they belong? eDP is essentially just Displayport, in my mind its primarily about getting the correct voltages to the pins on the display where it expects them which differs between both displays - The voltages are compatible tho.

eDP is eDP, but there is no EDID here so the laptop will be sending a 4K signal appropriate for its original panel and that probably can't be changed, and the lower res panel won't know what do do with it.

 

Not to mention that the backlight needs appropriate power that may or may not be available in the laptop, and a signal to control the backlight that the laptop won't provide since OLED doesn't use one so you'd have to hack something for that too.

Are you certain about there not being EDID? The document I found for the other Samsung OLED (Screenshot of the Pinout originates from that) mentions EDID, furthermore there are breakout boards for bare panels like this - Checking those, the DP lanes are literally just wired 1:1 to the input jack, at that point I figure there would *have to be* EDID (I believe that communicated via the AUX Channel / Pins which are available here and also seeminlgy just passed through on the breakout, 4x2 Data and 1x2 for AUX). I have definitely seen people swapping eDP displays with different resolutions before, just not between different display types with different pinous.

 

As for the Backlight, there indeed would be no brightness control by default, I was gonna add a simple PWM signal generator and a potentiometer for controlling that since I probably would need a custom PCB anyways to accomplish the rewiring in a clean fashion.
