摘要： A control module (28) for driving an LED array including N > 2 number of LED current drivers (34A-34H) connected to N number of electrical terminals (30A-30H), and Y > 2 number of transistor switches (36A-36C) connected between Y number of electrical terminals (32A-32C) and a common voltage point (38). An N number of column conductors (40A-40H) and a Y number of row conductors (42A-42C) are respectively connected to the N and Y number of electrical terminals, and at least one of the N x Y number of LEDs is connected between each pair of the column and row conductors. The control module includes a controller (50) for controlling the states of the LED current drivers and 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 provide a selected row conductor so that only those LEDs connected to a selected row conductor are activated.
