A current-selectable light-emitting-diode (LED) display includes pixels distributed in an array of rows and columns. The pixels are grouped in mutually exclusive clusters and cluster controllers are connected to each pixel in a cluster of pixels to control the pixels in the cluster to emit light. Each cluster controller comprises a selectable current source. Each of the selectable current sources can include cluster current sources that are responsive to a current-select signal to enable one or more of the cluster current sources. The pixels can include micro-LEDs and the cluster controller can be disposed between the micro-LEDs. The display can be disposed on a display substrate with signal wires. The signal wires can include separate wire segments that are electrically connected through regeneration circuits that regenerate the signals. The display can be an information display or a backlight.
