  • Advanced LCD packaging for military and severe environments
    Patent number: 7868983
    Abstract: The invention relates generally to a modular display panel for enclosing Commercial-Off-The-Shelf (“COTS”) display technologies. More particularly, the invention relates to a modular display panel for housing COTS light emitting or transmitting display subassemblies such as Liquid Crystal Displays (LCD) for military and other severe environments. The modular display assembly can comprise a base plate, a first frame, a window, a second, a circuit located, and a plurality of light emitting diodes mounted on the circuit board. The COTS light emitting or transmitting display subassembly can be connected to the second frame.
    Type: Grant

  • Optical compensation of cover glass-air gap-display stack for high ambient lighting
    Patent number: 7167309
    Abstract: Apparatus and methods relating to display stacks wherein one or more index matching layers are utilized to minimize reflectance at the boundaries of otherwise adjacent layers. More particularly, the present invention is directed to methods and apparatus relating to a multilayer display stack comprising a glass layer, a first index matching layer, a first intermediate layer, a second index matching layer, a second intermediate layer, and a light emitting display panel wherein: the glass layer, first index matching layer, first intermediate layer, second index matching layer, and second intermediate layer are each transparent or translucent, and comprise an index of refraction; the index of refraction of the first index matching layer is between the index of refraction of the glass layer and the first intermediate layer; and the index of refraction of the second index matching layer is between the index of refraction of the first intermediate layer and the second intermediate layer.
