Kai Schleupen, Steven Wright, "High Resolution TFT LCDs: The wave of the future?"

Tuesday, February 26, 2002, 1:30 PM-2:30 PM EST

MIT Media Lab, Room E15-054

David Boor

Recent advances in TFTLCD technology have allowed the development of ultra-high information content displays, far beyond common formats, such as UXGA 1600x1200. Recent display product offerings from IBM include 3.1 Mpixel 2048x1536 and 9.2 Mpixel 3840x2400 using dual-domain IPS liquid crystal mode. For many applications, the increased information content will significantly increase user productivity. At the same time, new technology developments have allowed the pixel density to be increased by a factor of two to three over present 100 ppi displays. For the first time, display image quality can match what the eye can resolve and can reach the quality of print. For this technology to gain acceptance and grow in the marketplace, a number of infrastructure issues must be overcome. One part of this talk will discuss the development of digital drive electronics architecture required for these displays. At 60 Hz data refresh, a 9.2 Mpixel display with 24-bit color requires a data rate over 1.7 GByte/sec, well beyond what can normally be accomplished with analog methods. Such high data rates place new demands on various components in the DVI and LVDS portions of the system and also challenge the capabilities of graphics card hardware. A second part of this talk will discuss other aspects of this display technology concerning the glass module, front of screen characteristics, human factors and application issues.

Kai Schleupen received his MS degree in 1989 and his PhD degree in 1995 for flat panel displays at the University of Stuttgart, Germany. His PhD thesis was on active matrix displays with fully integrated drivers on glass. From 1995 to 1996 he worked in the Display Research Department at AT&T Bell Labs in Murray Hill, New Jersey. In 1996, he joined the IBM T.J. Watson Research Center in Yorktown Heights, New York, where he is currently the manager of the Display Design and Electronics Department of the Advanced Display Technology Laboratory. His major focus of work is in all design aspects of high resolution direct-view displays for desktop and portable applications.

Steven Wright obtained his PhD at the University of California at Santa Barbara under Nobel Laureate Herbert Kroemer. He joined IBM Watson in 1982, working on high speed GaAs device materials and physics, and in 1991, he joined the flat panel display group. He presently serves on program committees for SID, the Color Imaging Conference, and shares responsibility for representing IBM for USDC.
