Light-emitting apparatuses are disclosed for use in an Light Emitting Diode (LED) printer or the like that include an LED array and a LED array driver integrated circuit (IC). The LED driver IC includes register and latching means for receiving and storing externally provided LED array drive signals, strobe signal generating means for sequentially generating strobe signals with mutually different time delays, and strobing circuitry. The strobing circuitry is used to control the operation of the LEDs of the LED array by generating a logical product (AND) of the LED array drive signals from the register and latching means and the strobe signals from the strobe signal generating means to provide sequential drive signals to different sections of the LEDs of the LED array that are based on the strobe signals from the strobe signal generating means. Clock generating circuitry is included in certain embodiments of the present LED array driver ICs for providing the strobe signal generating means with clock signals of a predetermined controllable frequency.
