This section shows information about the Newhaven LVDS Capacitive Display Set. The iMX8M Industrial Development Kit in this configuration is equipped with Yocto dunfell, kernel 5.4 to support LVDS display with a touchscreen layer. In this case the display is installed on the top of the iMX Development Baseboard.

Mechanical connection

When combined with the complete iMX8M Industrial Kit, the Display Set creates a compact, ready-to-use solution. To assemble them together, the following mechanical and electrical accessories were designed and selected to be part of the Display set:

  • TFT LCD 1024x600 Pixels display with LVDS interface and Capacitive Touch with SiS9509 controller
  • 4x Hex Standoff Threaded M3 30.00mm long [Manufacturer PN: 971300321]
  • 40 Position flat flex cable 50.80mm long [Manufacturer PN: 0150200427]
  • 6 pin touchscreen flat flex cable
  • necessary spacers

Voipac NHD LCD Fastener.png

Hardware connection

To enable smooth communication between the board and the display, connect the 40 Position FFC cable for LCD and 6 pin touchscreen FFC cable. To implement the display capabilities, following connections need to be made:

  • connection between LVDS Display and iMX Development Baseboard connector LVDS0 NHD (J12) using a 40 Position FFC cable
  • touchscreen connection between iMX Development Baseboard connector NHD Touch (J13) and Touchscreen 6 pin FFC cable
