Article Summary
Many of us still keep old LCDs that should have been discarded long time ago. There might be a good reason, however, to refrain from disposing of this obsolete equipment. By following a few simple steps, anyone can turn an old LCD into a privacy monitor with contents visible only to the person wearing a pair of special glasses (also home-built), while anyone else can only see a white surface.
