"3D LCD technology has existed since the very first commercial monitors were on sale, but they were prohibitively expensive and lacked the image quality of the current panel generation. The most popular form of 3D LCD technology is called autostereoscopic technology? and is able to provide a 3D image without any glasses!

This technology works by diverting each column of pixels to an individual eye, essentially halving the vertical resolution but providing a unique image to each eye. By displaying a correctly rendered image on the monitor it is then possible to trick the brain into believing that the two 2D images are a single 3D scene."
