Search on here there are hundreds of OEM screens that give a white screen because the driver is missing or misconfigured.

The photo doesn't show enough detail to be 100% sure, but it looks like one of the waveshare 3.5" compatible ones.

Got that card as a gift 3 days ago. Tried loading just the driver and wiped the SD card of its working rasbian and retropie install? Got kernel panic errors and no boot after. Recovery screen is only accessible thing. Not even sure what I did wrong.
Just a heads up. Backup any data that's important to you and or test on a random SD card first. GL
