  • Publication number: 20120019760
    Abstract: Method of preparation of surface coating of variable transmittance and an electro-optical layered appliance including the same comprises dispersing of liquid crystal microdroplets in hydrolyzable and polymerizable precursors and applying obtained mixture on a surface by spraying. Applying the material to the surface by spraying is intrinsically related to the synthesis processes because the properties of the surrounding environment (i.e. content of water and acidity, UV radiation) and the chemical reactions that take place during spraying have considerable influence on the properties (i.e. driving voltage, thickness of obtained layer). Obtained layered appliance comprises of a matrix material with dispersed microdroplets of liquid crystal obtained by the described method, electrically conductive transparent electrodes with contacts, a dielectric material, substrate and covering layers.

  • Patent number: 8098351
    Abstract: According to an exemplary embodiment, a liquid crystal on silicon (LCoS) structure includes a number of pixel electrodes overlying an interlayer dielectric, where diagonally adjacent pixel electrodes are separated by a gap. The LCoS structure further includes a self-planarizing passivation dielectric situated over the pixel electrodes and in the gap, where the self-planarizing passivation dielectric has a selected thickness. The self-planarizing passivation dielectric can be an Oxide-Nitride-Oxide (ONO) stack. The selected thickness of the self-planarizing passivation dielectric causes the self-planarizing passivation dielectric to have a substantially planar top surface. In one embodiment, the thickness of the self-planarizing passivation dielectric can be approximately equal to twice a width of the gap.
