Confirm the electrical interface

Name the interface and provide the controller or host details. Similar interface labels do not guarantee identical timing, voltage or command behavior.

  • RGB, LVDS, MIPI, SPI, MCU or custom drive
  • Logic and backlight voltage
  • Timing, frame rate and initialization
  • Driver IC and controller compatibility

Define the connector and pinout

Use one drawing that shows the viewing side, pin-one reference, contact side and connector orientation. This prevents mirrored pinouts and assembly mistakes.

  • Connector manufacturer and part number
  • Pitch, pin count and contact direction
  • Pin assignment and unused pins
  • Grounding, shielding and backlight connections

Review the FPC as a mechanical part

The FPC must reach the board without interference or excessive stress. The routing should be reviewed with the enclosure, connector height and assembly sequence.

  • Exit position and routing path
  • Bend radius and keep-out zones
  • Stiffener thickness and component clearance
  • Tolerances and assembly access

Build a focused sample test

The first sample test should confirm communication, image stability, backlight control, touch when applicable and repeatable assembly—not only whether the display turns on.

  • Power-up and initialization
  • Full-pattern and color checks
  • Temperature and cable-movement checks
  • Final drawing and pinout sign-off
