Abstract: Ferroelectric liquid crystal compositions including organic ion pair compounds wherein image sticking is reduced or eliminated. Use of the ferroelectric liquid crystal compositions in a ferroelectric liquid crystal display device allows for rapid image refresh rates without required a DC-balancing algorithm. The organic ion pair compounds provide electrical resistivity values for the compositions that result in reduced image sticking when the compositions are used in FLC display devices.

Abstract: Devices and methods are disclosed for improving image quality in a display system. The devices and methods adjust the display optical states based on the input image data. The devices and methods may compensate for temporal variation of the optical states in a display panel arrangement having a liquid crystal and an insulating layer due to a net DC field across the liquid crystal. The variation in optical states may be variation between the position of the optic axis of the liquid crystal for a zero net DC field drive waveform and a drive waveform with a net DC field across the liquid crystal. The variation of the optic axis of the liquid crystal may be due to ionic charge movement through the liquid crystal. The display panel arrangement may have a decay time constant of the liquid crystal and the insulating layer less than a maximum time that is visually acceptable for image sticking to persist on the display panel.
