Key questions and answers

How to switch the color bit count and scanning direction of this module?

Answer: Color switching through FRC pin: High level is 8-bit 16.77 million colors, low/floating is 6-bit 260000 colors; Switching scanning through DPS pins: low/floating is normal scanning, high level is reverse scanning.

What are the core parameters and lifespan of backlight drivers?

Answer: The backlight consists of 4 LED channels, with a typical current of 50mA and voltage of 21V per channel. The lifespan of the LED is 70000 hours at 25 ℃ and 60000 hours at 80 ℃, and constant current driving must be used.

What does the quality level Standard of this product mean and in which scenarios cannot it be used?

Answer: Standard level is applicable to equipment without life safety risks (industrial, car entertainment, home appliances, etc.); Not suitable for safety critical scenarios such as vehicle control, medical surgery, aerospace, nuclear control, etc. Such scenarios require prior application for Special/Specific level.
