National Semiconductor Develops Intra-panel Interface and Chipset for Samsung’s Next-Generation Chip-on-Glass Notebook Panels

National’s Advanced Bus System Interface and Chipset for Samsung Reduces System Cost and Enables Quick Gamma Changes

May 24, 2004

Society for Information Display (SID) Conference, Seattle, WA - May 24, 2004 - National Semiconductor Corporation (NYSE:NSM) and Samsung Electronics Co., Ltd. today announced the development of an advanced bus system interface (ABSI) and chipset for chip-on-glass (COG) notebook and monitor panels. National will license and sell the ABSI design and chipset exclusively to Samsung Electronics for one year. The ABSI design and chipset will be available to other panel manufacturers in early 2006.

"The ABSI design is a significant advancement in COG column driver technology. With the ABSI link and the serial gamma interface, National has made significant advancements in the state-of-the-art of timing controller and column driver system design," said Brian Berkeley, Vice President for the LCD Business at Samsung Electronics. "The chipset will go into production in the fourth quarter of 2004 and be used in Samsung’s next-generation notebook panels."

Utilizing a point-to-point architecture with a unique, current based, single-ended data link, ABSI efficiently transmits red, green and blue (RGB) data from the timing controller to the column drivers with low power and low electromagnetic interference (EMI). In addition, the column driver employs internal gamma references controlled by a serial voltage link to reduce the wire count connecting to the column driver.

"National and Samsung Electronics have a long history of collaborating on pioneering display electronics. We are delighted with the achievements of ABSI and with the effort Samsung has made in supporting this development," said Jeff Andersen, business director for National Semiconductor’s Flat Panel Displays Division.

The ABSI data link together with a serial gamma reference system significantly reduces the number of interconnect wires required enabling a space-efficient, low-cost, COG solution. The serial gamma feature not only reduces wire count but because each voltage reference value is digitally stored in the timing controller, it enables quicker development time for gamma changes. The ABSI product family supports both and 6- and 8-bit notebook and monitor panels.
