Unlike liquid crystal displays (LCDs), μLEDs are current driven devices. However, they may be similarly arranged in a two-dimensional array (matrix) of elements to form a display. Active-matrix μLED displays typically use current control circuits integrated with the display itself, with one control circuit corresponding to each individual element on the substrate, to create high-resolution color graphics with a high refresh rate. Such a structure results in a matrix of devices, where one (or more) device is formed at each point where a row overlies a column. There will generally be at least M×N devices in a matrix having M rows and N columns. Typical devices function like light emitting diodes (LEDs), which conduct current and luminesce when voltage of one polarity is imposed across them, and block current when voltage of the opposite polarity is applied. To control such individual μLED devices located at the matrix junctions, it may be useful to have two distinct driver circuits, one to drive the columns and one to drive the rows. It is conventional to sequentially scan the rows (e.g., conventionally connected to device cathodes) with a driver switch to a known voltage such as ground, and to provide another driver to drive the columns (which are conventionally connected to device anodes). In operation, information is transferred to the matrix display by scanning each row in sequence. During each row scan period, each column connected to an element intended to emit light is also driven.
