Frequently asked questions

What is the CFD977B LED driver IC?

The CFD977B is an LED display driver chip made by Chipfountain. It is a PWM (constant-current, pulse-width-modulated) driver used on the LED module to control each pixel's grayscale.

Does NovaStar support the CFD977B?

Yes — the CFD977B is in NovaStar's recognized driver-IC library, and NovaLCT can auto-configure it with Smart Settings. Exact support depends on your receiving card model and firmware; upload your config to our RCFGX viewer to confirm.

How do I find out which driver IC my LED panel uses?

Open your receiving card configuration file (.rcfgx) — it records the driver IC type and firmware version. Our free online RCFGX viewer reads this for you without installing NovaLCT.
