1. An LED module comprising:
- a rear wall with sidewalls extending outwardly therefrom;
a plurality of LEDs secured between said sidewalls;
driver means, including processing circuit means, secured between said sidewalls in communication with said plurality of LEDs, said processing circuit means including input means for receiving data from a preceding similar LED module, output means for transmitting data to a subsequent similar LED module, and memory means;
an electrical jack in communication with said processing circuit means, said electrical jack providing power and bi-directional communication of data to said processing means via said input means and said output means from a preceding similar LED module and to a subsequent similar LED module, respectively;
an aperture within said rear wall providing access to said electrical jack; and
means on at least one of said rear wall and said sidewalls for attaching the LED module to an external surface.

Abstract
The apparatus is a detachable LED module which is used to display a pixel on a display. The LED module includes a rear wall and side walls. A plurality of LEDs along with a processor with input and output capabilities are contained within the LED module. The rear wall includes an aperture to receive an electrical jack from the display so as to communicate data, power and commands to the LED module. The input and output capabilities of the processors along separate data paths allow modules to be "daisy-chained" together with data intended for a single module to be passed through a succession of modules while commands are monitored from the ribbon cables and power is drawn therefrom.
