Active control of light emitting diodes and light emitting diode displays |
| abstract |
Synchronization is provided for the LED display LED pixels so that the operation of one or more of all light emitting diode (LED) pixels can be initiated simultaneously or within milliseconds. LED displays and corresponding systems can include a controller configured to send communication signals to one or more strings of LED pixels. Active electrical elements within each LED pixel can be configured to receive communication signals, generate corresponding synchronization signals, and respond in a coordinated manner with all other LED pixels within a particular LED display. Mitigation of LED pixel failures within a LED string is provided where the controller is configured with bi-directional communication ports for communication with the LED string. In the fault mitigation process, the bidirectional communication ports can switch directions to provide communication signals to both sides of the LED string. |
