To setup the LCD, you need the components below:
1. A panel (support up to 24-bit dual channel) with LVDS interfaces.
2. An inverter for panel’s backlight power.
3. A LCD cable and an inverter cable.
For the cables, please follow the pin assignment of the connector to make a cable,
because every panel has its own pin assignment, so we do not provide a standard cable;
please find a local cable manufacture to make cables.
