摘要： The present disclosure relates to a TFT including a gate on a substrate; a gate insulation layer on the substrate and the gate, and a surface of the gate insulation layer being applied with a flattening process; an oxygen-rich layer on the gate insulation layer; an active layer on the oxygen-rich layer; a source and a drain on the active layer; and a passivation layer on the active layer, the source, and the drain. In addition, the present disclosure also relates to a manufacturing method of the TFTs and the array substrate having the TFTs. By applying the flattening process to the surface of the gate insulation layer and by forming the oxygen-rich layer on the gate insulation layer, the surface of the gate insulation layer is smooth so as to eliminate the oxygen vacancy defects on the surface of the gate insulation layer. Thus, the surface state of the gate insulation layer is stable.

摘要： A manufacturing method of carbon nanotube conductive microspheres, which can simplify the process, reduce the process, save cost, and reduce the impact of thermal mismatching, to ensure the conductive properties of conductive microspheres, and not pollute the environment. The carbon nanotubes are mixed in the polymer microspheres when the styrene monomer, the crosslinking agent and the initiator have a crosslinking reaction to form the polymer microspheres with a method of spray-granulation. Only one step is needed to prepare the conductive microspheres with carbon nanotube as the conductive medium, which can simplify the process, reduce the process, save cost. With mixing the carbon nanotube inside the polymer microspheres, the thermal mismatching between the carbon nanotubes and the resin can be illuminated, to ensure the conductive properties of conductive microspheres. Furthermore, the entire preparing process has no heavy metal salts; the bio-toxicity is reduced and no environmental pollution.

摘要： The present invention provides an alignment method of an FFS liquid crystal display panel. The method includes adding a light-sensitive small-molecule compound in a rubbing alignment material, carrying out rubbing alignment after formation of an alignment film, and afterwards, conducting boxing of the FFS liquid crystal display panel, and then applying an electrical voltage to cause liquid crystal molecules to rotate to a position substantially parallel to a substrate, and carrying out UV irradiation to cause polymerization of the light-sensitive small-molecule compound to form polymer bumps so as to keep the liquid crystal molecules in parallel to the substrate. The liquid crystal molecules, after the alignment, show a pre-tilt angle having a zero angle value and can, under the condition of providing a strong anchoring force of the alignment film, reduce the pre-tilt angle of the liquid crystal molecules and improve quality of displaying of the FFS liquid crystal display panel.
