Flat Panel Display Interface

The Flat Panel Display Interface product family is composed of two classes of chipsets. The first is FPD-Link which provides a narrow high speed interface between graphic controllers on the motherboard and the TFT-LCD panel in Notebook applications. The second class is LDI (LVDS Display Interface) which is enhanced from FPD-Link by supporting long cable drive for flat panel desktop monitor applications. Each class of product is described below. 

FPD-Link

The FPD-Link chipset is a family of interface devices specifically configured to support data transmission from the graphics controller to LCD Panels. The chipset employs LVDS, which is ideal for high speed, low power data transfer. With the use of MUX/DEMUX circuitry the overall size of the bus is reduced. This enables high resolution panels to be supported over a smaller interface, simplifing notebook hinge design while supporting larger classes of panel resolutions. The chipsets support SVGA, XGA, and SXGA panels primarily in Notebook applications. 

LVDS Display Interface (LDI)

The LDI chipset is a family of interface devices specifically configured to support data transmission from the graphics controller to LCD Panels in Desktop Monitor applications. To support long cable applications (>10m), an enhanced version of LVDS is employed. The enhancements include in the transmitters: selectable pre-emphasis and a simple low power DC Balancing scheme to open the eye pattern. The Receiver also offers a cable deskew function, that enables standard twisted pair cables to be used. LVDS delivers high speed, low power, low noise data transfer. 5.38Gbps of bandwidth is provided by the chipset at a 112MHz clock rate. With the use of MUX/DEMUX circuitry the overall size of the bus is reduced. This enables high resolution panels to be supported over a small cabled interface. The chipset supports SVGA, XGA, SXGA, UXGA, HDTV, and QXGA panels for high-resolution desktop displays and other image applications.
