A control module for driving an LED array, with the array including N number of LED current drivers connected to N number of electrical terminals of the module, and Y number of transistor switches connected between Y number of electrical terminals of the module and a common voltage point. N and Y are each at least three. An N number of column conductors and a Y number of row conductors are to be connected to the respective N and Y number of electrical terminals. At least one of the N×Y number of LEDs is connected between each pair of the column and row conductors. The control module further includes a controller for controlling the states of the N number of LED current drivers and the Y number of transistor switches so that, during a given LED drive period, all of the LED current drivers are activated and only one of the transistor switches is turned ON to provided a selected row conductor in which case only those LEDs connected to a selected row conductor are activated.
