Patent ID: 8884855

Claim:
A method of operating an electro-optic display apparatus, the display apparatus including a display device having image regions and a display driving system connected to the image regions by signal lines, the display driving system having a distributor for providing signals for driving the image regions via the signal lines, and the display driving system having a data input for selecting image regions, which data input is connected to an input of the distributor, each image region having an active display state in which the image region is driven with an active voltage signal, wherein 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 comprising: applying said first signal level to one of said image regions in response to receiving data on said data input of the display driving system, the data indicating that said one of said image regions is to be set to the active display state, applying the second signal level to said one of the image regions after said first signal level has been applied; and reapplying said first signal level to said one of the image regions, on the basis of said data which was received on the data input of the display driving system before applying the second signal level to said one of the image regions, and before receipt on said data input of the display driving system of further data indicating a further signal level to be applied to said one of the image regions.
