    Abstract: A display back panel may include a substrate, an insulating layer disposed on one side of the substrate and including a plurality of recesses, the plurality of recesses including a bottom surface, a first electrode disposed on a surface of the insulating layer away from the substrate, a pixel defining layer disposed on a surface of the first electrode away from the substrate and including a plurality of openings, a light-emitting layer disposed in the plurality of openings and covering the first electrode, and a second electrode disposed on a surface of the light-emitting layer away from the substrate. Therein, the first electrode may reflect waveguide light laterally propagated by the light-emitting layer, thereby improving a light-emitting efficiency of the light-emitting layer. Further, the reflected waveguide light may not be absorbed by the second electrode, thereby enhancing an external quantum effect of the light-emitting layer.

    Abstract: A pixel structure. The pixel structure includes a base substrate; an insulating island on the base substrate; a light emitting element on a side of the insulating island away from the base substrate; an insulating layer on the base substrate and surrounding the insulating island, the insulating layer spaced apart from the insulating island by a groove; and a reflective layer on a lateral side of the insulating layer surrounding a periphery of the light emitting element, and configured to reflect light laterally emitted from the light emitting element to exit from a light emitting surface of the pixel structure. The insulating layer has a height relative to a main surface of the base substrate greater than a height of the insulating island relative to the main surface of the base substrate.

    Abstract: A sub-pixel structure including: a light emitting device including a first electrode layer and a second electrode layer arranged opposite to each other, the first electrode layer and the second electrode layer together defining an optical microcavity. A first refractive layer is provided at a light exit surface of the light emitting device, the first refractive layer operable to reflect a portion of light emitted by the light emitting device back into the optical microcavity for interference. A second refractive layer is provided at a side of the first refractive layer facing away from the light exit surface, the second refractive layer operable to reflect a portion of the light emitted by the light emitting device and transmitted through the first refractive layer back into the optical microcavity for interference.

    Abstract: This disclosure relates to an organic electroluminescent device, comprising: a light emitting layer comprising a plurality of light emitting regions arranged in an array, each light emitting region being an organic electroluminescent region; an electron transport layer, a cathode and a transflective layer successively disposed in a first direction from the light emitting layer towards a light emergent side of the organic electroluminescent device starting from the light emitting layer; and a hole transport layer, an anode and a reflective layer successively disposed in a second direction opposite to the first direction starting from the light emitting layer. In addition, in a projection region of at least one light emitting region on the hole transport layer, the hole transport layer has at least two portions of different thicknesses for selecting a wavelength range of light emitted by the at least one light emitting region and/or enhancing the emitted light.
