Punch data and ODI start production 1200dpi small LED print head

OKI data and its engaged in LED business Oki digital image (ODI) Co developed a long and wide and 600dpi paragraph the same, but the size of the 1200bpi of the LED print head, and has begun mass production. By adopting the bonding technology developed by ODI (epifilm), the miniaturization is realized. The technique is to remove the epitaxial layer of the light from the compound semiconductor, and then use the intermolecular bonding force to bind to the silicon driving IC. LED print head the development drive wiring diagram in IC, in addition to reducing the size of the IC driver, the company also plans to two by using wire bonding (wire bonding), reduce the cost and reduce the installation chip and other measures to improve LED materials.
