Flat panel autostereoscopic display with wide viewing zone using time-division multiplexing backlight

In this paper the authors attain a flat panel autostereoscopic display with time-division multiplexing directional backlight that can be seen by multiple viewers at the same time. The proposed system realizes thin directional backlight system by combining dot-matrix light source, hexagonal convex lens array with delta alignment, and a directional diffuser. Directional diffuser can blur the seam of lens array and can smooth the uneven light intensity in each elemental lens, which leads to better quality of presented image. © 2013 Society for Information Display.
