FPD33684A/ FPD33684B
Low Power, Low EMI, TFT-LCD Column Driver with
RSDSInputs, 64 Grayshades, and 384 Outputs for
XGA/SXGA Applications
General Description
The FPD33684 Column Driver is a direct drive, 64 gray level,
384 output, TFT-LCD column driver with an RSDSdata
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.
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.
