FPD48084
LCD TV TFT-LCD Timing Controller with PPDS
Interface
General Description
The FPD48084 Column Driver is a direct drive, 256 gray
level, 384 output, TFT-LCD column driver. This device is
ideally suited for LCD TV applications, supporting WXGA
resolution. It provides the capability to display 16,772,26
colors (24-bit color) with a large dynamic output range for
wide viewing angle technologies. This scheme supports digi-
tal independent gamma from the TCON, and minimizes re-
quired trace routing and PCB size.
The FPD48084 uses National’s PPDS
interface (Point to
Point Differential Signaling) to reduce wire count, increase
driving distance, enable advanced features, and lower over-
all system cost. Coupled with an FPD8020x timing controller,
the FPD48084 is capable of providing independent color for
each of the three subpixel colors (red, green, and blue),
enabling the color temperature and balance control that is
needed to provide cinema quality video performance for
advanced LCD TV applications.
