FPD33680

Low Power, Low EMI, TFT-LCD Column Driver with

RSDS Inputs, 64 Grayshades, and 480 Outputs for

SXGA/UXGA Applications

General Description

The FPD33680 is a direct drive, 64 gray level, 480 output,

TFT-LCD column driver with an RSDS™ data interface. It

provides the capability to display 262,144 colors (18-bit

color) with a large dynamic output range for twisted nematic

applications. It is targeted to support SXGA applications up

to a 75Hz refresh rate and UXGA applications up to a 60Hz

refresh rate. Output voltages are gamma corrected to pro-

vide a direct mapping between digital video and LCD panel

brightness.

An RSDS (Reduced Swing Differential Signaling) interface is

used between the timing controller and the column driver to

minimize EMI and reduce power.

The column driver with its interface offers a low power, low

EMI column driver solution with direct-drive dynamic range

and dot-inversion addressing.
