FPD33584
Low Power, Low EMI, TFT-LCD Column Driver with
RSDS Inputs, 64 Grayshades, and 384 Outputs for
XGA/SXGA Applications
General Description
The FPD33584 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
FPD33584 column drivers, the FPD33584 can support XGA
(8 drivers) or SXGA (10 drivers) applications. Output volt-
ages are gamma corrected to provide a direct mapping
between digital video and LCD panel brightness. The 85MHz
operating frequency allows the FPD33584 to meet the re-
quirement of high refresh rate applications (i.e. XGA moni-
tors with a 75Hz refresh rate).
An RSDS (Reduced Swing Differential Signaling) interface is
used between the timing controller and the column driver to
minimize EMI and reduce power.
Features
n RSDS (Reduced Swing Differential Signaling) data bus
for low power, reduced EMI and small PCB foot print
n 85MHz maximum operating frequency at VDD1=3.0V
(70MHz at VDD1=2.7V)
n Pin compatible with Samsung S6C0666
n Ideal for XGA and SXGA applications
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 Four externally programmable gamma curves
n Low offset, High voltage outputs for high contrast in a
large range of display panel applications
n Optional, high current, repair amplifiers
