A liquid crystal display panel includes a color filter, a thin film transistor substrate in opposition to the color filter, a liquid crystal layer provided between the color filter and the thin film transistor substrate and a sealant provided corresponding to the mark regions and surrounding the liquid crystal layer. The invention further provides methods for preparing the redispersible powder and the aqueous dispersion, wherein the methods include preparation of an oil-in-water nanoemulsion or microemulsion and solvent removal. The service module transfers messages between connectors and the application collaboration module. It further correlates the set of consistent ICs thus obtained with an equivalent circuit and simultaneously provides an input for future use.
