We have characterized the MLC00089 antiferroelectric liquid crystal (AFLC)
mixture in terms of tilt angle, reflectance, and response time as a functio
n of applied voltage. The derived highest contrast ratio was about 700 to 1
. We also applied the simulated thin-film-transistor (TFT)-type circuit to
direct drive a hardwired Si-based chip filled with the AFLC mixture by vary
ing the values of storage capacitor and gate on-time. We found that adding
a storage capacitor is effective to increase the signal if the gate on-time
of the TFT is shorter than the AFLC response time. We also used quasi-DC d
riving with a short gate on-time on the hardwired chip as well as a Si-base
d reflective 1024 x 1280 (SXGA) microdisplay. We have accomplished the effe
ctive operation of the microdisplay using 5-frame quasi-DC driving with ext
rapolated polarity-frame inversion at 360 Hz suitable for field-sequential
color displays using pulsed-light sources (light-emitting diodes) as well a
s optical storage applications.
