    摘要： Example embodiments presented herein may be directed towards an antiferroelectric liquid crystal (AFLC) device and a method for writing greyscale in the AFLC device. The device may comprise two electrode substrates confining an antiferroelectric liquid crystal (AFLC) material. The method may comprise driving the AFLC device with an electrical signal, where the electrical signal does not comprise a direct current holding voltage for a writing of at least a portion of written levels of grey. The method may also comprise inducing a greyscale configuration in the AFLC device as a function of the driving, wherein the inducing is temperature independent. The method may also comprise applying a high-frequency signal, to stabilize a well-defined horizontal tilt plane of the antiferroelectric or, in particular, of the orthoconic antiferroelectric. The examples embodiments presented herein provide for fast and precise writing of greyscales in orthoconic antiferroelectrics.
