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 digital independent gamma
from the TCON, and minimizes required 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 overall 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.
