FPD33684 Low Power, Low EMI, TFT-LCD Column Driver with RSDS Inputs, 64 Grayshades, and 384 Outputs for XGA/SXGA Applications May 2002 FPD33684A/ FPD33684B Low Power, Low EMI, TFT-LCD Column Driver with RSDS™ Inputs, 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 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 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 FPD33684 offers a low power, low EMI column driver solution with direct-drive dynamic range and dot-inversion addressing.
