Abstract
Light-emitting diode (LED) packages and more particularly error detection in LED packages is disclosed. LED packages are arranged for cascade communication as part of a larger LED display. A separate active electrical element is integrated with each LED package for facilitating active matrix addressing from a data stream, checking input error detection codes, and generating new output error detection codes to the data stream. Each electrical element within each LED package is separately capable of changing one or more portions of received data in the data stream, transmitting the changed data to the next downstream LED package, and generating output error detection codes based on the changed data. When the active electrical element identifies corrupted data based on input error detection codes, the generated output error detection codes may be intentionally corrupted so downstream LED packages will also identify the respective data as being corrupted.
