A 17-in.video rate full color Ferroelectric Liquid Crystal Display(FLCD)with 720×916 dots, using τ-Vmin mode was developed. The full color moving images with 256 gray levels for each color was displayed by the digital gray scale method combining 2 bits spatial dither and 4 bits temporal dither. The response speed of FLC material is very fast(12μs/line)and the 4 bits temporal dither with video rate scanning was realized. The FLCD shows a contrast ratio of 60 : 1, a wide viewing angle due to the in-plane switching, and strong shock stability(20 kg/cm^2)due to the spacer walls structure. This paper presents a high potential of FLCD for the large-size direct-view video-rate full-color simple-passive-matrix flat panel display.
