The invention proposes a motor-vehicle headlamp, of the type including a main optical system which comprises, arranged from back to front overall along a main optical axis, a main light source, a main reflector of the elliptical type, and a converging main lens,. A driver circuit produces first and second differential currents from a digital signal that drive first and second transmission lines. As the user scrolls or moves off of the originally displayed window, information related to the unrealized tiles that were once realized is stored so that selection of unrealized tiles is possible. A layer of substantially boron free silicon oxide material has a first thickness over the substrate within the gap and has a second thickness less than the first thickness over the wordline constructions.
