The sub-pixels are on the base substrate, each of at least part of the plurality of sub-pixels includes a light-emitting element, the pixel-defining pattern includes a plurality of openings and a defining portion that surrounds the plurality of openings, the defining portion includes at least one cavity surrounding at least one opening, and the first filling structure is in the cavity, and a surface, away from the base substrate, of the first filling structure is farther away from the base substrate than a surface, away from the base substrate, of at least a portion of the light-emitting functional layer in the opening.

Abstract: A power transmission and transformation project acceptance method based on building information modeling (BIM) and point cloud measurement includes: S1: constructing a BIM model based on a design drawing, where the BIM model includes standard parameters of key components of a power transmission and transformation project; S2: obtaining point cloud data, and constructing a point cloud data model based on the point cloud data, where the point cloud data model includes actual parameters of the key components of the power transmission and transformation project; S3: comparing the BIM model with the point cloud data model to obtain construction acceptance data; and S4: visualizing the construction acceptance data and outputting an acceptance report to complete acceptance of the power transmission and transformation project. The BIM model and the point cloud data model are compared to implement rapid and efficient acceptance of the power transmission and transformation project.

Abstract: A display device is provided in embodiments of the disclosure relating to the field of display technology, the display device including: a liquid crystal display panel; and an organic electroluminescent display panel provided opposite to the liquid crystal display panel and configured to function as a backlight source for the liquid crystal display panel; the liquid crystal display panel has a display region defined therein, and comprises a plurality of pixel units arranged in an array and located in the display region, each of the plurality of pixel units comprising a plurality of sub-pixel units; the organic electroluminescent display panel has a light-emitting region defined therein and opposite to the display region, and comprises a plurality of light-emitting units arranged in an array and located in the light-emitting region, each of the plurality of light-emitting units comprising a plurality of light-emitting sub-units; and an area of each of the plurality of sub-pixel units is smaller than an area of

Abstract: An organic light-emitting diode (OLED) component includes a substrate; a pixel defining layer and a plurality of first electrodes over the substrate; an insulating layer correspondingly disposed over the pixel defining layer; a first light-emitting layer over each first electrode; and a charge generation layer over the first light-emitting layer. The plurality of first electrodes are physically separated from one another by the pixel defining layer. The insulating layer is configured to facilitate manufacturing of the OLED component, such that after formation of the charge generation layer without a mask, portions thereof positionally corresponding to any two adjacent first electrodes are physically separated by the insulating layer. The OLED component can be a white light organic light-emitting diode (WOLED) component including at least one other light-emitting layer in addition to the first light-emitting layer.
