Frequently asked questions
What is the TBS5267A LED driver IC?
The TBS5267A is an LED display driver chip made by TB Silicon. 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 TBS5267A?
Yes — the TBS5267A 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.
