May 24, 2004 — National Semiconductor Corp. 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 chipset will go into production in the fourth quarter of 2004 and [will] be used in Samsung’s next-generation notebook panels,” said Brian Berkeley, VP for the LCD Business at Samsung Electronics.
Utilizing a point-to-point architecture with a 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,” said Jeff Andersen, business director for National Semiconductor’s Flat Panel Displays Division.
