Abstract
The described embodiments relate generally to liquid crystal displays (LCDs), and more particularly to methods for extending a glass portion of a display to an edge of a display housing. In one embodiment, a thin cover glass layer is provided between a color filter glass layer and an upper polarizer. The thin cover glass layer is supported along an edge of the display by a filler material that can include a foam dam and a glass spacer or adhesive filler. The filler material allows the cover glass layer to be supported without damaging any drivers or circuits located on an underlying thin film transistor glass layer. In another embodiment, a glass spacer circuit with integrated drivers and circuitry on its lower surface can support the cover glass along the edge of the display.
