there is no controller needed, every single laptop LCD panel from ~10 years old was parallel. Then we got LVDS. Laptop screens from ~7(?) years ago have LVDS deserializer chip on the Tcon pcb (DS90C562/SN75LVDS86), you can desolder that and connect directly to parallel bus. Never screens integrated Flatlink(lvds) receiver inside main lcd driver chip.

LVDS is just serialized parallel video. Serializer chips are ~$5 in singles on Mouser. Combining Pee DPI output with SN75LVDS84 ($2.5 if you order 10 from china) will allow you to connect any modern <=1366x768 resolution (single lvds channel limit) Laptop LCD screen. Those can be free if you have a broken laptop. You could even drive older "HDReady" 32' TV LCD with pee this way.
