Abstract
A charge storage circuit for a pixel comprises a charge storage node. First and second series-connected transistors () are provided for selectively isolating the charge storage node from a first voltage input (,SL) for supplying a data voltage. The circuit is provided with a voltage follower circuit for replicating a voltage at the charge storage node () at another node in the circuit thereby to reduce the drain-source voltage across the second transistor (). The first transistor forms part of the voltage follower circuit.
