SAMSUNG Electronics Agrees to Use National`s Reduced Swing Differential Signaling (RSDS) Technology in Display Panel Products

on Jul 30, 1999

- RSDS Gaining Momentum as Technology of Choice for Building Next - Generation, High-Resolution Digital Display Interfaces

SANTA CLARA, Calif. - July 30, 1999 - National Semiconductor Corporation and Samsung Electronics Co. Ltd. today entered into a technology licensing agreement for the use of National`s power-saving, low-noise, Reduced Swing Differential Signal (RSDS) digital interface technology. Samsung will provide column drivers for Thin-Film-Transistor (TFT) Liquid Crystal Display (LCD) panels using National’s RSDS technology. A typical TFT-LCD chipset consists of National`s universal interface XGA panel timing controller and Samsung`s XGA column driver.

`RSDS effectively resolves the problems we have encountered supporting higher-resolution displays without increasing power usage, bus interconnect and overall cost,` said Oh-Hyun Kwon, Sr. VP & General Manager at Samsung Electronics. `By partnering with National, Samsung can offer its customers an optimal TFT-LCD solution and significantly strengthen our presence in the LCD driver market of the future.`

`Another win for National in the flat panel display interface market, we`re anticipating that the adoption of RSDS technology will track the widespread success of the LVDS technology upon which RSDS is based,` said Mitchell Abbey, product marketing manager at National Semiconductor. `National and Samsung`s collaboration addresses a real problem for customers designing display applications where TFT LCDs are commonly used. These devices are designed to work at new lows with regards to both power consumption and EMI-radiated noise-essential qualities for systems with extended battery life, reduced weight and lower cost.`

The bus interface between the panel timing controller and column drivers has historically been a major source of EMI and power dissipation inside the panel, due to the common use of TTL-level signaling on this bus. However, with National`s timing controller and Samsung`s column drivers, RSDS interface signals replace TTL signals on the bus. By reducing the signal swing level and implementing a differential signaling technique, RSDS results in significantly lower power consumption and EMI levels compared to the TTL bus interface.

RSDS is a derivative of the Low Voltage Differential Signal (LVDS) technology used in National`s FPD-Link interface chipset, a widely-used standard for notebook motherboard to flat panel display (FPD) interface.
