  • Patent number: 10921672
    Abstract: A switchable window includes an electro-optical layer of or including an anisotropic gel of polymer stabilized highly chiral liquid crystal, for example, blue phase liquid crystal, encapsulated in, for example, a mesogenic polymer inclusive shell, that forms a self-assembled, three-dimensional photonic crystal that remains electro-optically switchable under a moderate applied voltage (e.g., electric field). The liquid crystal (LC) arrangement may be achieved via a polymer assembled blue phase liquid crystal system having a substantially continuous polymer structure case surrounding well-defined discrete bodies of liquid crystal material arranged in a cellular manner. These assembled structures globally connect to form a matrix. This provides for reduction of angular birefringence of highly chiral LC systems, which advantageously reduces haze in applications such as switchable windows.

  • Patent number: 10067370
    Abstract: A polymeric dispersed liquid crystal light shutter device and system and method for forming the same are disclosed. In one embodiment of the system, a catoptric form having a shape is subjacently positioned below a pre-cure or un-cured polymer dispersed liquid crystal (PDLC) light shutter device having liquid crystals dispersed in a polymer binder system between two substrates. Light is applied during curing. The liquid crystal microdroplet sizes vary according to the shape of the catoptric form such that domains of smaller liquid crystal microdroplet sizes correspond to the shape and domains of larger liquid crystal microdroplet sizes correspond to negative space relative to the shape. Upon tuning an electric field, the PDLC light shutter device changes states from presenting a surface having an image formed by non-scattering regions contrasted against opaque scattering regions, to a surface characterized by mostly or entirely clear, non-scattering light transmittance.

  • Patent number: 9929377
    Abstract: A light emitting device having a structure in which oxygen and moisture are prevented from reaching light emitting elements, and a method of manufacturing the same, are provided. Further, the light emitting elements are sealed by using a small number of process steps, without enclosing a drying agent. The present invention has a top surface emission structure. A substrate on which the light emitting elements are formed is bonded to a transparent sealing substrate. The structure is one in which a transparent second sealing material covers the entire surface of a pixel region when bonding the two substrates, and a first sealing material (having a higher viscosity than the second sealing material), which contains a gap material (filler, fine particles, or the like) for protecting a gap between the two substrates, surrounds the pixel region. The two substrates are sealed by the first sealing material and the second sealing material.
