  • Publication number: 20180182895
    Abstract: The present disclosure discloses a thin film transistor, an array substrate and their manufacturing methods, and a display apparatus. The method for manufacturing the thin film transistor of the present disclosure comprises a step of forming an insulation layer, wherein the step of forming the insulation layer further comprises forming a siloxane material layer, oxidizing the siloxane material layer such that an inorganic silicon film is formed on a surface of the siloxane material layer, and curing the oxidized siloxane material layer to obtain the insulation layer. In this disclosure, the outer layer of the insulation layer is an inorganic silicon film which is a commonly-used material for making the insulation layer in prior art, and the inner layer of the insulation layer is made of the siloxane material having a low dielectric constant and high chemical stability.

  • Patent number: 9905793
    Abstract: Disclosed are an organic light-emitting device and a method of manufacturing the same, and a display device. The organic light-emitting device includes: a first electrode layer, a second electrode layer, and an organic light-emitting layer sandwiched between the first electrode layer and the second electrode layer, wherein the first electrode layer includes a first transparent conductive layer, a nanostructured layer and a second transparent conductive layer sequentially, and the second transparent conductive layer is closer to the organic light-emitting layer than the first transparent conductive layer. In the organic light-emitting device, silver nanowires or carbon nanotubes can be introduced between the two transparent conductive layers of the first electrode layer, which facilitates the injection equilibrium of electrons-holes, thereby improving the quantum efficiency. Therefore, the organic light-emitting device has a high luminous efficiency.
