There are several formats for time-shared stereoplexed electronic displays. A stereo-vision format is the technique used for assigning pixels (or lines, or fields) for the left and right images, enabling them to be available at the display screen as an image with true binocular stereopsis. These days most graphics workstations intrinsically output a high field rate, and don't require the above-and-below solution once used for workstations and now more commonly used on PCs. Another approach uses spatial multiplexing of rows or columns, either for individual selection devices or autostereoscopic displays. A new format, the white-line-code (WLC) system, was developed for PCs and offers a low cost but high resolution. This format doesn't care if the left and right fields are in interlace or progressive scan modes, and it doesn't care about field rate.
