Light modulator and substrate having an energy conversion layer

A transparent substrate for use in a light modulator, the light modulator having an optical layer, the transparent substrate having at least one electrode system applied on the substrate, the electrode system comprising a stack of a substrate-side electrode, an energy conversion layer, and an optical layer-side electrode, the optical layer-side electrode being arranged to modulate an electric field in the optical layer, the energy conversion layer being configured to convert between energy external to the substrate and a voltage difference between the substrate-side electrode and the optical layer-side electrode,

• wherein the electrode system is arranged across the substrate in multiple lines, the substrate-side electrode and the optical layer-side electrode being arranged in multiple electrode lines,
• wherein the multiple electrode lines in the substrate-side electrode of the at least one electrode system and the multiple electrode lines in the optical layer-side electrode of the at least one electrode system align when projected orthogonally on the substrate,
• wherein the energy conversion layer is arranged across the substrate in multiple lines, a dielectric being arranged between the multiple lines of the energy conversion layer
• the energy conversion layer of the at least one electrode system extends beyond the borders of the multiple electrode lines in the substrate-side electrode and beyond the borders of the optical layer-side electrode when projected orthogonally on the substrate.
