Method of reducing artefacts in an electro-optic display by using a null frame

摘要

We describe a method of reducing artefacts in an image displayed by an active matrix electro-optic display and display driver, the electro-optic display driver comprising a plurality of active matrix pixel drivers each driving a respective pixel of the electro-optic display, each active matrix pixel driver having an associated storage capacitor coupled to a common backplane connection of the display driver, pixels of the electro-optic display having a common pixel electrode, the method comprising: driving the electro-optic display with a null frame during a power-down procedure of the display.
