    Abstract: Embodiments of the present disclosure provide a transparent display assembly, including a transparent display panel which has a light emitting face for displaying an image and a back face opposite to the light emitting face. The transparent display assembly further includes a light adjustment structure arranged on a side of the back face of the transparent display panel; in a display mode, the light adjustment structure blocks an background light and prevents the background light from entering the transparent display panel through the light adjustment structure; in a non-display mode, the light adjustment structure allows the background light to enter the transparent display panel through the light adjustment structure.

    Abstract: The present disclosure provides an organic light-emitting diode device (OLED) structure for compensating blue light emission. The OLED structure includes a substrate with a thin-film transistor layer, the substrate being substantially transparent; and a first electrode layer on the substrate, the first electrode being substantially transparent; a first light-emitting layer on the first electrode layer with one or more light-emitting portions for emitting light for compensating blue light. The OLED structure also includes a charge generation layer (CGL) with a reflective portion, the CGL on the first light-emitting layer, the reflective portion having a transmission rate for light emitted by the first light-emitting layer; a second light-emitting layer on the CGL with one or more light-emitting portions for emitting the blue light; and a second electrode layer with a reflectivity on the second light-emitting layer.

    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.
