Electrostatic Discharge Protection Structures for Liquid Crystal Displays

摘要

A liquid crystal display having an outer layer such as a thin-film transistor layer and an inner layer such as a color filter layer may be mounted in a metal device housing. Transparent conductive coating material may be formed on display layers. The transparent conductive coating material may include a layer on the upper surface of the thin-film transistor layer, a layer on the lower surface of the color filter layer, and an edge coating that extends between the upper surface layer and lower surface layer. Electrostatic discharge protection structures for the display may include a conductive elastomeric gasket that couples the upper surface layer to an inner surface of the housing, a conductive tape that couples the lower surface layer to the inner surface, and a conductive material on the inner surface that contacts the edge coating.
