Abstract: A stacked organic light-emitting diode, a display device and a manufacturing method of a stacked organic light-emitting diode are disclosed. A stacked organic light-emitting diode includes at least two light-emitting units in a stacked arrangement and a charge generation layer disposed between the adjacent light-emitting units, wherein the charge generation layer includes a first material layer, an electron injection layer disposed on the first material layer and a second material layer disposed on the electron injection layer. By means of said stacked organic light-emitting diode and manufacturing method thereof, it can achieve excellent electron injection effect, even in the case of manufacturing an inverted-type stacked organic light-emitting diode (the lower electrode is a cathode).

Abstract: An OLED device and a preparation method thereof, and a display device are provided. The OLED device comprises a substrate and a plurality of functional layers disposed sequentially on the substrate. One functional layer of the plurality of functional layers is a transition functional layer, the transition functional layer comprises a first sub-layer and a second sub-layer provided on the first sub-layer, the first sub-layer and the second sub-layer are made of a same material; and the first sub-layer is prepared by using a first process, and the second sub-layer is prepared by using a second process different from the first process.

Abstract: A composition for photosensitive dielectric material is provided. The composition includes 4 to 10 percent by weight of a polymer material, 1.5 to 10 percent by weight of a crosslinking agent, 0.32 to 2 percent by weight of a photoacid generator (PAG) and 78 to 94.18 percent by weight of solvent, based on a total weight of the composition.

Abstract: A miniature generator includes a carrier having a tubular shaft on the inside, a substantially C-shaped permanent magnet mounted on the tubular shaft inside the carrier, a match mounted on the tubular shaft inside the carrier and joined to the permanent magnet to keep the permanent magnet in a slightly unbalanced condition for allowing rotation of the permanent magnet upon movement of the carrier by an external force, and a winding holder sleeved onto the carrier and having wound thereon multiple windings for inducing an induction current upon rotation of the permanent magnet in the carrier.

Abstract: This invention provides a method for manufacturing a patterned metal layer, which forms a metal layer on a sacrificial layer having light-thermal conversion characteristic on a first substrate. The metal layer is patterned onto a second substrate by a laser transfer printing method to form a patterned metal layer on the second substrate. The sacrificial layer between the patterned metal layer and the first substrate can absorb laser light to protect the patterned metal layer from absorbing laser light and being heated. The oxidation of the patterned metal layer is prohibited.

Abstract: An aluminum hair curler comprises: a hollow aluminum tube having a plurality of trenches on the outside thereof; and two terminals having a plurality of dowel pins and a plurality of notches on the outer periphery thereof. The aluminum hair curler is characterized in that the terminals are inserted into the openings of the hollow aluminum tube, respectively. By using the high heat-conductivity aluminum metal, the hair can be shaped rapidly. In addition, the aluminum hair curler can be cleaned easily and used repeatedly, thereby providing easy maintenance and cleanness.
