Abstract
Active control of light emitting diodes (LEDs) and LED packages within LED displays is disclosed. LED packages are disclosed that include a plurality of LED chips that form at least one LED pixel for an LED display. Each LED package may include an active electrical element that is configured to receive a control signal and actively maintain an operating state, such as brightness or grey level while other LED packages are being addressed. Active electrical elements may include active circuitry that includes one or more of a driver device, a signal conditioning or transformation device, a memory device, a decoder device, an electrostatic discharge (ESD) protection device, a thermal management device, and a detection device, among others. In this regard, each LED pixel of an LED display may be configured for operation with active matrix addressing.
