Abstract: An organic light-emitting diode (OLED) includes: a first electrode, a first light-emitting layer disposed on a side of the first electrode, a charge generation layer disposed on a side, away from the first electrode, of the first light-emitting layer, a second light-emitting layer disposed on a side, away from the first light-emitting layer, of the charge generation layer, and a second electrode disposed on a side, away from the charge generation layer, of the second light-emitting layer. The OLED further includes: a process conversion layer, disposed between the first electrode and the second electrode, and configured to fill an uneven region between the first electrode and the second electrode.

Abstract: A pixel unit, a display panel, a display device and a method of manufacturing a pixel unit. The pixel unit includes a first sub-pixel unit and a second sub-pixel unit, each sub-pixel unit includes a first electrode, an emission layer, and a second electrode stacked on a substrate. An emission lifespan of the emission layer of the first sub-pixel unit is smaller than that of the emission layer of the second sub-pixel unit. An area of an orthographic projection of the emission layer of the first sub-pixel unit on the substrate is equal to that of the emission layer of the second sub-pixel unit on the substrate. An area of an orthographic projection of the first electrode of the first sub-pixel unit on the substrate is greater than an area of an orthographic projection of the first electrode of the second sub-pixel unit on the substrate.

Abstract: A crucible. The crucible includes a crucible body having an opening formed at the top thereof. The crucible further includes a sealing cover and an elastic element. The sealing cover is configured to seal the crucible in a first position and open the crucible in a second position. In the first position, the sealing cover forms a detachable sealed connection with the crucible body. The elastic element is arranged between the sealing cover and the crucible body, where the elastic element is in a compressed state when the crucible is sealed by the sealing cover in the first position. Correspondingly, the present disclosure also provides an evaporation preparation device, evaporation equipment and an evaporation method. The present disclosure can reduce the deterioration of the material to be evaporated and the direct contact between human body and the material.
