1. A substrate for use in a light modulator, the substrate comprising
at least one driving electrode applied to the substrate, the driving electrode being arranged in a pattern across the substrate, the pattern of the driving electrode across the substrate comprising multiple repeated building blocks, the building block comprising
one or more electrodes extending in at least 2 different directions across the building block, the electrodes in the building blocks forming the at least one driving electrode, wherein an electrode in a building block comprises multiple nodes where the electrode branches, the nodes being electrically connected through electrode lines, the multiple nodes and connecting electrode lines forming a tree, the electrode comprising at least a first node where the electrode branches into at least three electrode lines, the first node being directly connected through an electrode line to a second node and to a third node, the electrode branching into at least three electrode lines at the second node and at the third node.
