Layout & dimensional drawing of HXD256HU-V1 LCD display driver board shown below for your reference:
HXD256HU-V1 LCD screen control board adopts a shared LVDS/eDP dual-mode interface, supporting two mainstream industrial display output protocols. It is a composite panel interface that balances compatibility and versatility. The single interface supports both LVDS and eDP protocols, eliminating the need for additional reserved interface space on the driver board. One single board is compatible with the vast majority of industrial LCD display panels on the market, significantly reducing selection costs. The detailed pin definitions for the 40-pin LVDS/eDP output interface are listed in the table below. Please refer to the product datasheet for further information.
