The present invention relates to a dispersion of hybrid organic-inorganic nanocomposite molecules comprising discrete inorganic silica nanoparticles that are covalently bonded to organic polymers, wherein the dispersion has a high solid content and high silica content with low coagulum. And b) performing a lit-up test by establishing an electrical coupling between the probes and a plurality of contacts on the liquid crystal display panel. Information relating to services provided in a building may be displayed to a user, and the user’s selection may be received by the mobile device. The two-dimensional projected images are assigned the index information corresponding to the index information assigned to the relevant three-dimensional graphics.
