We developed two mobile-device size autostereoscopic integral videography (IV) displays with field sequential color (FSC) liquid crystal displays (LCDs) and micro lens arrays. IV is an autostereoscopic video technique based on integral photography. The FSC-LCD has a different backlight from that of conventional LCDs. The backlight is produced by red, blue, and green light emitting diodes (LED) instead of by cold cathode fluorescent lamps, and each LED emits light sequentially. IV based on FSC-LCD doesn't cause color moires because the FSC-LCD does not require color filters. One FSC-LCD IV display is 5-inch diagonal with 256×192 lenses and 20 ray directions. Its base FSC-LCD is 300ppi with 1280×768 pixels. The other FSC-LCD IV display is 4.5-inch diagonal with 192×150 lenses and 80 ray directions. Its base FSC-LCD is 498ppi with 1920×1200 pixels. In this paper, we first describe the problems of a previous conventional LCD-based IV displays, and then describe the principle of the IV displays based on the FSC-LCDs. Next, we analyze the IV displays by a plenoptic sampling theory. Lastly, we compare three versions of the IV displays, two based on the FSC-LCDs and one based on the conventional LCD.
