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
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. FEATURES
n RSDS™ (Reduced Swing Differential Signaling) data bus for low power, reduced EMI and small PCB foot print n Up to 85MHz clock n Supports both XGA and SXGA timing 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 Externally programmable gamma characteristic n Very low off...
