Leaky lightguide/LED row-backlight, column-shutter display

The authors arrayed leaky fused-quartz lightguides, each illuminated by GaAlAs light-emitting diodes, to make a row-addressable backlight. It was much more efficient than a DC-plasma row-backlight that was also made. Test patterns were displayed by operating the backlight with a ferroelectric liquid-crystal shutter array, and gray-scale capability was demonstrated.<
