Frequently asked questions
What is the TBSA1664 LED driver IC?
The TBSA1664 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.
Can a NovaStar receiving card drive the TBSA1664?
The TBSA1664 is not in NovaStar's default driver-IC library, but many NovaStar receiving cards can still drive it depending on the card model and firmware. The reliable way to confirm is to upload your receiving-card config to our free RCFGX viewer, or call us at 321-747-3220.
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.
