Transparent roof panel having an isolated center unit

A transparent panel for use in a vehicle roof of a vehicle, the transparent panel comprising:

• a layered stack comprising:
• a first transparent pane comprising a first main surface and a second main surface, opposite the first main surface;
• a second transparent pane comprising a third main surface, facing the second main surface, and a fourth main surface, opposite the third main surface, the second transparent pane comprising a through hole extending between the third and the fourth main surface;
• and
• an electrically conductive assembly arranged between the second and the third main surface, the electrically conductive assembly comprising:
• a first terminal arranged in a first area of the layered stack, the first area being adjacent to a circumferential edge of the through hole;
• a second terminal arranged in a second area of the layered stack, the second area being adjacent to a circumferential edge of the transparent panel;
• a third terminal arranged in a third area of the layered stack;
• a fourth terminal arranged in a fourth area of the layered stack, the fourth area being adjacent to the circumferential edge of the transparent panel;
• and
• a visually-transparent conductive layer comprising a first conductive layer section and a second conductive layer section, the first and the second conductive layer sections being electrically isolated from each other, wherein
• the first conductive layer section electrically couples the first terminal and the second terminal and is arranged in a first intermediate subarea;
• and
• the second conductive layer section electrically couples the third terminal and the fourth terminal and is arranged in a second intermediate subarea,
• thus providing an anode connection and a cathode connection;
• wherein each of the first and second intermediate subareas has an optical transmissivity higher than an optical transmissivity of each of the first and third areas, and optionally higher than an optical transmissivity of each of the second and fourth areas;
• and
• an electric apparatus mounted on the fourth main surface covering the through hole and first area, the electric apparatus being electrically coupled to the electrically conductive assembly through the through hole.
