<p>A method of changing the liquid crystal phase of bistable, cholesteric liquid crystals in a display is provided. In the display there is provided at least two active display areas with inactive display areas lying between said active display areas, and a D.C voltage is applied for a predetermined period of time to neighbouring active display areas, thereby causing the liquid crystal phase of the inactive display areas between the active areas to changed to a predetermined state. In such way, mechanical pressure marks in cholesteric liquid crystal displays can be removed. A display adapted for this method is also disclosed.</p> |
