A print head, including: a plurality of chips disposed in a linear array; respective pluralities of first and second matrix drivers on each the chip connected to first and second channels, respectively; and for each chip, first groups of light-emitting diodes (LEDs). Each first group of LEDs includes: a second group of LEDs, with a first number of LEDs, connected to a respective first matrix driver; and a third group of LEDs, with the first number of LEDs, connected to a respective second matrix driver. LEDs in each first group of LEDs are disposed in a staggered arrangement; and the respective pluralities of first and second matrix drivers are for activating in sequence the LEDs in the second and third groups of LEDs, respectively. |
