This is the most critical step. The model number is almost always printed on a sticker on the back of the display panel. Examples include LC470EUF , DV430FHM-NN1 , or LD420WUB . Write it down exactly as it appears.
The 51-pin interface standard features a : 51 pin lvds pinout datasheet
The 51-pin connector is a high-density interface designed to transmit large amounts of video data with minimal electromagnetic interference (EMI). Unlike smaller 30-pin connectors used for HD (720p) panels, the 51-pin layout typically supports "Double Channel" 8-bit or 10-bit color depths, which are required for 1920x1080 resolutions.
