    Abstract: An electronically switchable privacy device suitable for use in display devices is described. The electronically switchable privacy device comprises a first transparent electrode layer, an electronically switchable layer disposed adjacent to the first transparent electrode layer, and a second transparent electrode layer disposed adjacent to the electronically switchable layer and opposite the first transparent electrode layer. The second transparent electrode layer comprises a transparent substrate layer having a plurality of microstructured ribs extending across a major surface of the transparent substrate layer such that the microstructured ribs form an alternating series of ribs and channels, each channel having channel walls defined by adjacent ribs. A plurality of transparent electrode members comprising a transparent electrode material are disposed on at least one channel wall in a corresponding plurality of the channels; and a bus member provides electrical connectivity across the plurality of transparent electrode members. A spacer element disposed in the electronically switchable layer keeps the first transparent electrode layer spaced apart from the second transparent electrode layer. A portion of the electronically switchable layer at least partially fills the plurality of channels and makes electrical contact with the plurality of transparent electrode members. The electronically switchable layer comprises an electronically switchable material capable of modulation between high and low light absorption states upon application of a direct current voltage across the first and second transparent electrode layers.

    Abstract: Light sources are disclosed. A disclosed light source includes an optically reflective cavity that includes an input port for receiving light and an output port for transmitting light, a lamp that is disposed at the input port, and an optical stack that is disposed at the output port. The optical stack includes a forward scattering optical diffuser that is disposed at the output port and has an optical haze that is not less than about 20%, and an optical film that is disposed on the optical diffuser. The optical film enhance total internal reflection at the interface between the optical film and the optical diffuser. The optical film has an index of refraction that is not greater than about 1.3 and an optical haze that is not greater than about 5%. The optical stack also includes a reflective polarizer layer that is disposed on the optical film. Substantial portions of each two neighboring major surfaces in the optical stack are in physical contact with each other.
