Abstract: The invention relates to a method for preparing a composite metal oxide hollow fibre. A certain stoichiometry of composite metal oxide raw material and a polymer binding agent are added to an organic solvent, and mixed mechanically to obtain an evenly dispersed spinning solution having a suitable viscosity. After defoaming treatment, the spinning solution is extruded through a spinneret and, after undergoing a certain dry spinning process, enters an external coagulation bath; during this period, a phase inversion process occurs and composite metal oxide hollow fibre blanks are formed. The blanks are immersed in the external coagulation bath and the organic solvent is displaced; after natural drying, the blanks undergo a heat treatment process; during this period, polymer burn off, in situ reaction, and in situ sintering processes occur to obtain the composite metal oxide hollow fibre.

Abstract: A lighting apparatus includes a driver, a bottom cover, a light source module, a lens module, a light passing cover and a base plate. The bottom cover has a first central opening a driver container for storing the driver. The light source module has multiple LED modules and a second central opening. The lens module has a third central opening and multiple diffusion lenses respectively placed above the multiple LED modules. The lens module is fixed to the bottom cover to make the light source module, the driver, the lens module and the bottom cover as a portable module. The first central opening, the second central opening and the third central opening together form a main central opening. The base plate may be fixed to an installation platform.

Abstract: The present disclosure provides an alignment film manufacturing method, a liquid crystal display panel, and a liquid crystal display. The alignment film manufacturing method includes: providing a substrate; defining an active display area and a sealant area on the substrate, wherein the sealant area is a strip area arranged around the active display area, and there is a predetermined distance between the sealant area and the active display area; arranging an alignment film on the substrate, wherein the alignment film covers at least a part of the active display area; and etching the alignment film, so that an edge of the alignment film is located between an edge of the active display area and the sealant area. By the above-mentioned one or more implementations, the present disclosure may improve an adhesion force between the sealant and the substrate.
