| 摘要 |
In a method of operating a liquid crystal device having a liquid crystal composition with smectic-A properties, a first waveform is applied to optically clear the device so that it is substantially transparent to visible light and a second waveform is applied to disorder the material of the liquid crystal composition to afford a strongly light-scattering state. The first waveform has a higher frequency than the second, waveform, and the method comprises applying a modified waveform to partially clear at least a portion of the device from the light-scattering state |

1. A method of operating a liquid crystal device having a liquid crystal composition with smectic-A properties, in which a first waveform is applied to optically clear the device so that it is substantially transparent to visible light and a second waveform is applied to disorder the material of the liquid crystal composition to afford a strongly light-scattering state, wherein the first waveform has a higher frequency than the second waveform, the method comprising applying a modified waveform to partially clear at least a portion of the device from the light-scattering state. |
