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

摘要： A first embodiment of the invention permits an extension of battery life through detection of the display synchronization signals of a computer and a power management system. The power management system also eliminates need for batteries through use of a 5V power source from pin 9 of the VGA port. A second embodiment improves the ease of use and the utility of the 3D system through removable glasses with improvements over the previous design. These embodiments have improved manufacturability through the use of design that is tolerant of poor quality, low cost components with low electrical tolerances
