A USB C cable maybe used to drive the display for demonstration purposes from interfaces such as laptop/computer, these power source origins do not supply the required current (assuming 5V 500mA)
The microcontroller to detect VBUS connection, this will indicate a low energy power source, if this is the case the brightness of the display must be driven at a lower brightness to prevent overload at the origin
