FPD03784
Low Power, Low EMI, TFT-LCD Column Driver with Dual,
TTL Bus Inputs, 64 Grayshades, and 384 Outputs for
XGA/SXGA Applications
General Description
The FPD03784 Column Driver is a direct drive, 64 gray level,
384 output, TFT-LCD column driver with a dual bus, TTL
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 FPD03784 column drivers, the FPD03784 can support
both XGA (8 drivers) or SXGA (10 drivers) applications.
Output voltages are gamma corrected programmably to pro-
vide a direct mapping between digital video and LCD panel
brightness.
The FPD03784 offers a low power, low EMI column driver
solution with programmable output drive current and
direct-drive dynamic range, and dot-inversion addressing.
