n Supports digital independent gamma from TCON

n 256 Gray levels per color (24–bit color)

n High voltage dynamic range 9.6V to 14.1V Analog

supply voltage : VDDA = 10.0V to 14.5V

n Digital supply voltage : VDDD = 2.25V to 2.75V

n 125MHz maximum differential interface operating

frequency

n LCD TV interface protocol controls column driver

configuration

n Available in TCP or COF

n Internal pattern generation for panel self-test

n Supports both Dot and N-Line inversion

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.
