FPD03784 Datasheet | National Semiconductor

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 provide 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.
