Abstract
A trim panel assembly includes a printed foil extending for a first area, a printed circuit board disposed overtop the foil, the printed circuit board extending for a second area smaller than the first area, and a light guide disposed overtop the printed circuit board and having a perimeter. The perimeter is inset from the printed foil, and surrounds the printed circuit board, forming a sealed interface with the printed foil. At least a portion of the perimeter of the light guide is beveled. A reflector is disposed overtop the light guide. In an electronic assembly the reflector, the light guide, the printed circuit board, and the printed foil are disposed at least partially in a cavity of a molded support panel. The molded support panel is substantially planar, and a semi-transparent material is overmolded directly onto and overtop the electronic assembly and the molded support panel.
