abstract = "An addressing technique allowing continuous-tone color
images to be rendered on thin-film-transistor/liquid
crystal displays having bilevel drivers is described.
The technique uses multiple subfields per frame, with
driver voltages changed synchronously with the field
data. By using N bits of data per pixel, excitation is
applied to the display one bit-plane per field for N
consecutive fields. The technique is analyzed, its
benefits and limitations discussed, and experimental
results presented. Up to 16 gray levels have been
demonstrated with good image quality.",
