Abstract
An electronic display includes a controller transmitting display data from a data communication port. Modules are electrically connected to each other in a series connection. Each of a first module and a last module in the series connection receives the display data directly from the controller and transmits the display data to intermediate modules in the series connection. The intermediate modules pass the display data along the series connection in a first direction until the display data is received for a second time by the last module, and in a second direction until the display data is received for a second time by the first module. Each of the modules controls activation of a respective plurality of lighting elements based on the received display data.
