A host microcontroller communicates with them through I2C interface and uses a command set to configure and control the LED drivers, cap-sense touch buttons, GPIO pins and other embedded functions.

Additional analog and digital dimming capabilities such as 8-bit dot correction will help compensate for LED luminous mismatch and PWM control will adjust the display brightness.
