FPD33684A/ FPD33684B

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

™

RSDS Inputs, 64 Grayshades, and 384 Outputs for

XGA/SXGA Applications

General Description

Features

™

n RSDS (Reduced Swing Differential Signaling) data

bus for low power, reduced EMI and small PCB foot

The FPD33684 Column Driver is a direct drive, 64 gray level,

384 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. When used in a bank with other

FPD33684 column drivers, the FPD33684 can support both

XGA (8 drivers) or SXGA (10 drivers) applications. Output

voltages are programmably gamma corrected to provide a

direct mapping between digital video and LCD panel bright-

ness.

n Up to 85MHz clock

n Supports both XGA and SXGA timing

n Supports notebook and monitor applications

n Smart Charge Conservation for low power consumption

n 64 Gray levels per color (18-bit color)

n Supports both Dot and N-Line inversion

n Externally programmable gamma characteristic

n Very low offsets for artifact-free images

n High voltage outputs for high contrast in a large range of

display panel applications

™

An RSDS (Reduced Swing Differential Signaling) interface

is used between the timing controller and the column driver

to minimize EMI and reduce power.

The FPD33684 offers a low power, low EMI column driver

solution with direct-drive dynamic range and dot-inversion

addressing.

n Optional, high current, repair line buffers

n Available in 2 common gamma reference curves
