    摘要: Embodiments of the present disclosure provide an OLED device, a method of manufacturing the OLED device, and a display panel. The OLED device comprises: a substrate, a first electrode layer, a color filter layer, a light emitting layer and a second electrode layer. The first electrode layer is one of an anode layer and a cathode layer and comprises: a first sub-electrode layer disposed on the substrate; and a second sub-electrode layer electrically connected with the first sub-electrode layer. The color filter layer is disposed on the first sub-electrode layer and the second sub-electrode layer is disposed on the color filter layer. The second electrode layer is the other of the anode layer and the cathode layer and the light emitting layer is disposed between the second electrode layer and the second sub-electrode layer of the first electrode layer.

    摘要: Embodiments of the present invention disclose a display back plate. The display back plate comprises: an array substrate; and a pixel define layer formed on the array substrate and for defining an organic light emitting unit. An accommodation space is provided in the pixel define layer and a water absorbent material is provided within the accommodation space; the accommodation space has an opening formed in an upper surface and/or a lower surface of the pixel define layer; and the accommodation space is separated from the organic light emitting unit such that the water absorbent material within the accommodation space is spaced away from the organic light emitting unit. Embodiments of the present invention enable absorption of water vapor inside the organic light emitting display device, to prevent the adverse affection of water vapor on performance of the organic light emitting display device, so as to prolong service life of the organic light emitting display device.

    摘要: A light emitting element, includes a first light emitting layer and a second light emitting layer sequentially stacked; and an intermediate layer between the first light emitting layer and the second light emitting layer, and being in direct contact with the first light emitting layer on one side and in direct contact with the second light emitting layer on another side. Each of the intermediate layer, the first light emitting layer, and the second light emitting layer includes a same host material. The intermediate layer is a non-light emitting layer, and is an undoped layer absent of a dopant for emitting light. The light emitting element is configured to emit a composite light including the first light of the first wavelength range and the second light of the second wavelength range. The first wavelength range includes wavelength longer than the second wavelength range.
