1. A light emitting assembly comprising:
an array of light emitting diode (LED) devices and an array of micro controller chips arranged in an array of micro-matrices, each micro matrix including a matrix of LED devices electrically connected with a micro controller chip, and each micro controller chip is to switch and drive a corresponding matrix of LED devices;
distribution lines to electrically couple a plurality of microcontroller chips of the array of microcontroller chips to one another to form a microcontroller network; and
wherein at least one microcontroller chip is configured to:
receive a digital input with a digital input pad;
drive an associated matrix of LED devices at a standard frame rate, or a content dependent frame rate; and
function as a repeater device within the microcontroller network, wherein the repeater device is to:
relay or retransmit the digital input from a first relay output pin or pad to one or more first additional microcontroller chips; and
relay or retransmit the digital input from a second relay output pin or pad to one or more second additional microcontroller chips.
