We are succeeded in developing new LED printheads using new LED arrays integrated with IC drivers. The LED arrays consisting of epitaxial layer of about 2 μm thick are bonded on the IC drivers. The performance test of the LED printhead has shown very promising characteristics in higher printing resolutions and higher printing speeds.
