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 provide
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.
