RT5927 Scan/Decode Chip

Q: What is the RT5927 chip?

The RT5927 is a row/scan decode chip made by Risetek used on LED display modules. It is not a pixel driver IC — instead of setting pixel grayscale, it handles the panel's multiplexed scan addressing (selecting which row group is lit). A scan LED panel uses a decode/scan chip like this together with a pixel driver IC.

The RT5927 is an LED display row/scan decode chip from Risetek recognized by NovaStar's control system. This page covers what it does, datasheet, and which NovaStar receiving cards and firmware support it.

Does NovaStar support the RT5927?

Yes — the RT5927 is in NovaStar's recognized decode/scan-chip library. Because a firmware version supports a specific group of driver ICs paired with a specific group of decode chips, exact support depends on your receiving card and firmware version. Upload your config to our RCFGX viewer to confirm, or call 321-747-3220.

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

Open your receiving card configuration file (.rcfgx) — it records both the pixel driver IC and the scan/decode chip plus the firmware version. Our free online RCFGX viewer reads this for you without installing NovaLCT.
