Claim:
1. A method comprising: producing a control component for lamination to an optical media component comprising an optical active layer, the control component comprising an array of pixel electrodes and an array of electronic switching devices for controlling the electric potential at said array of pixel electrodes, and a contact element for an electrically conductive connection to a common electrode of said optical media component; wherein said control component comprises lower and upper conductor layers defining electrodes of said array of electronic switching devices, and said lower layer defines said contact element; depositing one or more insulating layers over said array of electronic switching devices and said contact element; forming, at least through the one or more insulating layers, via-holes (a) for electrically conductive connections between the electronic switching devices and the respective pixel electrodes of the pixel electrode array, and one or more via-holes (b) disposed laterally beyond a lateral edge of said optical active layer and extending down to the lower conductor layer for an electrically conductive connection between said contact element and a part of said common electrode beyond said lateral edge of the optical active layer of said optical media component; and thereafter depositing conductive material to fill said via-holes (a) and said one or more via-holes (b) down to said contact element.
