Abstract
A passive-matrix controller provides a control signal to each column of multiple columns of components, a driver for each column wire, and a multiplexer. Each column of components is connected to a column wire. The driver provides a drive signal in response to the control signal and the multiplexer comprises an output connected to each column wire and an input connected to each driver and connects the inputs to the outputs in response to a multiplex signal from the passive-matrix controller. The components can be inorganic micro-light-emitting diodes.
