  • OKI Develops Industry’s First 1.1 Inch QVGA High Brightness LED

    OKI Digital Imaging, a subsidiary of OKI Data Corporation (a subsidiary that develops, manufactures, and markets LEDs), announced it has succeeded in developing a 1.1 inch QVGA (Quarter Video Graphics Array) LED display while reducing power consumption to one-tenth that of conventional LCDs.

    According to OKI, this achievement is the direct result of a new company technology that enhances luminance efficiency, based on refinements of its proprietary Epi Film Bonding technology that permit two-dimensional deployment.

    This new technology applies the Epi Film Bonding technology to mount thin-film LEDs onto a metal board in a manner permitting high reflection and radiation.

    “Featuring the world’s first 65-micrometer pitch between LED chips, this LED display also realizes high density to deliver high-definition images while maintaining diminutive dimensions,” the company says.

    OKI claims that since it is self-illuminating, the new display features faster response, more compact dimensions, and lower power consumption than LCD displays that require a separate light source. It also features high contrast (over 5000:1) for high visibility even in bright daylight.

    “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.

    Ha added that the firm 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.

    OKI informed they will manufacture the LED display at the newly-acquired LED manufacturing facility in Gunma prefecture, Japan. Shipments of samples are expected to begin by the end of fiscal year 2010.

  • Japan to use audience rating system to discover IPTV programme preferences

    A viewer rating system developed by Oki Electric Industry is to be used in Japan to collect information on the viewing habits of IPTV users.
    Existing ground-based broadcasting systems have the means to gather viewership data, such as user preference and viewer history.
    Broadcasting companies say this information is important in enabling them to improve services.
    However, until now there has been are no equivalent user information collection functions for IPTV services.
    OKI’s IPTV Audience Rating Information System allows service providers, with the authorisation of users, to obtain information about when and which channel and programs the users watched.
    The system will collect the viewership data in the form of an “audience rating library” on the user’s device, which will then be encrypted, sent to and registered in the database server at the IPTV distribution centre.
    This information will then be printed out as viewership reports which service providers can offer to programme producers.
    Masa Saito, general manager of IP Systems Division at OKI, said the system, which uses the company’s eVideo technology, would ensure the efficient delivery of high quality video over IP networks.
    “We have been proposing the technology to handle audience rating information to ASTAP, Asia’s communication standard organisation and FG-IPTV in ITU, the UN’s agency for information and communication technologies, as we believe open standards are important in improving IPTV service and technologies,” he said.
    “We will continue our activities within IPTV-GSI, the IPTV standardisation initiative, to promote international standardization to enrich IPTV services.”
    Telecom carriers in Japan are expected to increase their IPTV service provisioning with the start of next-generation network (NGN) services, and as the ITU works on setting international standards.
