    摘要: A method of operating an electro-optic display apparatus, wherein the display apparatus includes a display device having image regions and a display driving system having a data input for selecting image regions. The data input is connected to the input of a distributor for providing signals for driving the image regions. Each image region has an active display state in which the image region is driven with an active voltage signal. The active voltage signal includes a first signal level which sets an image region to the active display state and a second signal level different from said first signal level and which is applied for a shorter duration than said first signal level. The method comprises the following three steps: (1) applying the first signal level to one of said image regions in response to receiving data on said data input indicating that said image region is to be set to the active display state, (2) applying the second signal level to said image region after said first signal level has been applied; and (3) reapplying said first signal level before receipt of further data for said image region on said data input.
