Parallel RGB TTL and panel-link LVDS transport pixel data differently and are not directly interchangeable. RGB uses multiple single-ended data and timing lines; LVDS serializes pixel information onto differential pairs. A bridge is required when the host and panel interfaces do not match.
Key differences
| Item | RGB TTL | LVDS |
|---|
| Signal form | Parallel single-ended data and timing | Serialized differential pairs |
| Wire count | Higher | Lower |
| Typical reach | Short board/FPC connections | Longer internal cable connections |
| EMI/noise | Layout and simultaneous switching require care | Differential signaling improves common-mode rejection |
| Compatibility | Pinout, voltage, timing and mapping remain model-specific |
Selection checklist
- Confirm host output and panel input from datasheets.
- Match native resolution, refresh, color depth and timing.
- For LVDS, verify channel count and JEIDA/VESA color mapping.
- For RGB, verify bus width, DE/sync mode and signal voltage.
- Check connector, pinout, cable length and grounding.
- Validate signal integrity, EMI, boot and temperature in the final system.
A passive cable cannot convert RGB to LVDS. An active bridge/controller adds firmware, power, latency and lifecycle considerations.
Use the RGB TTL guide, LVDS category and controller matching inquiry.
