Stereoscopic LCD shutter glass driver system

摘要: The preferred embodiment a stereoscopic LCD shutter glass driver system requires only total of 3 CMOS integrated circuit chips in order to convert horizontal and vertical sync signals into drive signals. A negative charge pump is used increase the voltage thereby reducing 3D crosstalk image. video signal input shown with passthrough connection intended for direct hook-up television or CRT monitor. first flip flop detects pump. stable, predictable field ID produced by whose two complimentary outputs act as inputs second chip which produces glasses. third “common” that sent both shutters. each shutter. swap between shutters implemented switch located at output flop.
