We have developed a new 1200 dots-per-inch (dpi) light emitting diode (LED) print head for high-quality digital color printers in the next generation. The LED print head is suitable for high-speed color printer print heads. In order to achieve the high performance of the LED print head, we have developed an original 1200 dpi LED array chip with matrix structured wiring. Moreover, the LED array chip realizes a “Low cost LED print head” in which the number of bonding wires and driver integrated circuit (IC) chips on the LED print head has been decreased to less than half, compared to the conventional 1200 dpi print head.
