Abstract
A light emitting diode (LED) print head arranged to receive a set of raw print data. The print head includes a plurality of LED array chips each having a plurality of LEDs, wherein each LED of the plurality of LEDs includes a process direction position. The print head further includes at least one matrix drive circuit arranged to control activation of the plurality of LEDs in response to the set of raw print data and at least one real-time print data compensation circuit, wherein the at least one real-time print data compensation circuit receives the set of raw print data and delays transmitting the set of raw print data to the at least one matrix drive circuit based on a relative relationship between the process direction position of each LED.
