Abstract
A display apparatus includes a display device and a display driving system having a data input connected to a distributor for providing signals for driving image regions. Each image region has an active display state in which it is driven with an active voltage signal including a first signal level which sets the image region to the active display state and a second signal level applied for a shorter duration than the first signal level. Operation includes (1) applying the first signal level to an image region in response to receiving data on the data input indicating that the image region is to be set to the active display state, (2) applying the second signal level to the image region after said first signal level has been applied, and (3) reapplying the first signal level before receipt of further data for said image region on the data input.
