Figure 3. Block Diagram
Note:
HEG=High Ef
fi
ciency Green LED.
HER=High Ef
fi
ciency Red LED.
The pixels are not bit addressable.
A stream of 48 bits must be clocked in.
The
fi
rst or LSB (the least signi
fi
cant bit) will control LED
number 48 in pixel 24.

The last or MSB (the most signi
fi
cant bit) will control LED number
1 in pixel 1.
The LEDs are direct current driven. It is not recommended that
more than 24 LEDs are kept ON continuously. If more LEDs need
to be ON then reduce brightness by modulating the V
B
pin.
