No universal "51-pin LVDS standard" exists. Search the (e.g., AUO G185XTN01.0 , BOE HT185WX1 ). Useful resources:
Always verify if the pin numbering is "1-to-51" straight across or "Zig-zag" (Top row left to right, then bottom row right to left). Check the connector's mechanical datasheet before designing a PCB.
