There is no universal standard 51-pin LVDS pinout.
The 51-pin configuration is rare and typically found in:
Most standard LVDS panels use 20, 30, 40, or 41 pins (e.g., 41-pin for 2-channel LVDS with backlight control). A 51-pin connector often combines LVDS video + backlight + touch + I²C or SPI control on one connector. 51 pin lvds pinout datasheet
A true 51-pin LVDS connector does not use 51 signal pins. Instead, the pins are allocated across Power, LVDS Data Pairs, Control, and Auxiliary buses. Technical Write-up: 51-Pin LVDS Interface Pinout ❗ First
The table below represents the most widely adopted de facto standard for 51-pin LVDS (used by Sharp, NEC, Mitsubishi, and AU Optronics industrial panels). Custom industrial LCD panels (e
