OKI Digital Imaging has developed a 1.1 inch QVGA LED display while reducing power consumption to one-tenth that of conventional LCDs.
This is the direct result of development in its LED print head technology that enhances luminance efficiency using an extension of its proprietary Epi Film Bonding technology into a two-dimensional array.
This array has the world’s first 65-micrometer pitch between LED chips to give a high definition image and, as it is self-illuminating, the new display has a faster response, smaller size and lower power than LCD displays that require a separate light source. It also features high contrast (over 5000:1) for high visibility even in bright daylight.
OKI Digital Imaging will manufacture the LED display at the LED manufacturing facility in Gunma prefecture, Japan, that it acquired from Reneasas back in July. Shipments of samples are expected to begin by the end of fiscal year 2010.
“The new technology has made it possible for us to develop a groundbreaking LED display that provides high definition images while maintaining compact dimensions,” said Hiroshi Kikuchi, President of OKI Digital Imaging. “The development of the world’s first thin-film-bonding technology in 2006 marked a significant milestone for the OKI Group. As shown by today’s announcement, that technology laid the foundations for continuing developments in LEDs. The OKI Group plans to leverage the expertise and technical knowledge accumulated over 20 years of experience with LED printing to develop new technologies in other areas and to expand its LED-related businesses.”
