Connect to a two-lane DSI host

Required

Use a carrier designed for this FPC and a host with a two-lane DSI PHY. Check both supply rails and connect the separate constant-current backlight driver before the first display test.

Bench checks

  • Match FPC contact 1 to the carrier and verify the power rails before releasing reset. Confirm DSI clock and both data-pair polarities.
  • Start the host with the initialization sequence and DSI timings supplied for WF70D4SYAUMNN0, then display solid colors. If the panel remains dark, verify backlight current and DSI initialization separately.
