Abstract: A method of operating a device comprising: a first conductor layer defining a plurality of source conductors each associated with a respective group of transistors, and a plurality of drain conductors each associated with a respective transistor; a semiconductor layer defining semiconductor channels between said source and drain conductors; a second conductor layer defining a plurality of gate conductors each associated with a respective set of transistors, and one or more storage capacitor conductors capacitively coupled to the drain conductors for a respective set of transistors; the method comprising: using the gate conductors to switch the transistors between on and off states; and using the storage capacitor conductors to reduce the conductivity of one or more semiconductor layer connecting the drain conductor of each transistor in the on state to source and/or drain conductors other than those associated with that transistor.

Abstract: 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.
