  • Publication number: 20210280824
    Abstract: The present invention discloses an organic light-emitting display panel, a manufacturing method thereof, and an encapsulation film thereof. In this invention, an auxiliary encapsulation layer is disposed on an outer side of an inorganic layer, and the auxiliary encapsulation layer at least covers a bending region of the inorganic layer and a boundary region of the inorganic layer. Even if the inorganic layer cracks or peels in the bending region and the boundary region, a channel of water and oxygen generated at a cracked place or a peeling place is blocked by the auxiliary encapsulation layer, thereby ensuring an ability of the encapsulation film to block water and oxygen into an organic light-emitting device.

  • Publication number: 20210233247
    Abstract: This application relates to a medical image segmentation method, a computer device, and a storage medium. The method includes: obtaining medical image data; obtaining a target object and weakly supervised annotation information of the target object in the medical image data; determining a pseudo segmentation mask for the target object in the medical image data according to the weakly supervised annotation information; and performing mapping on the medical image data by using a preset mapping model based on the pseudo segmentation mask, to obtain a target segmentation result for the target object. Because the medical image data is segmented based on the weakly supervised annotation information, there is no need to annotate information by using much labor during training of the preset mapping model, thereby saving labor costs. The preset mapping model is a model used for mapping the medical image data based on the pseudo segmentation mask.

  • Publication number: 20210164965
    Abstract: A method of characterizing a serum or plasma portion of a specimen in a specimen container includes capturing a plurality of images of the specimen container from multiple viewpoints, stacking the multiple viewpoint images along a channel dimension into a single stacked input, and processing the stacked input with a single deep convolutional neural network (SDNN). The SDNN includes a segmentation convolutional neural network that receives the stacked input and outputs multiple label maps simultaneously. The SDNN also includes a classification convolutional neural network that processes the multiple label maps and outputs an HILN determination (Hemolysis, Icterus, and/or Lipemia, or Normal) of the serum or plasma portion of the specimen. Quality check modules and testing apparatus configured to carry out the method are also described, as are other aspects.

  • Publication number: 20210133971
    Abstract: A method of characterizing a serum or plasma portion of a specimen in a specimen container provides a fine-grained HILN index (hemolysis, icterus, lipemia, normal) of the serum or plasma portion of the specimen, wherein the H, I, and L classes may each have five to seven sub-classes. The HILN index may also have one un-centrifuged class. Pixel data of an input image of the specimen container may be processed by a deep semantic segmentation network having, in some embodiments, more than 100 layers. A small front-end container segmentation network may be used to determine a container type and boundary, which may additionally be input to the deep semantic segmentation network. A discriminative network may be used to train the deep semantic segmentation network to generate a homogeneously structured output. Quality check modules and testing apparatus configured to carry out the method are also described, as are other aspects.

  • Patent number: 10930892
    Abstract: An organic light-emitting diode (OLED) display panel and a method of manufacturing the same are disclosed. The OLED display panel includes a phase-compensated liquid crystal layer and a linear polarizer disposed on an organic light-emitting device layer. The phase-compensated liquid crystal layer is disposed between the organic light-emitting device layer and the linear polarizer. Polarized light is generated after external light passes through a linear polarizer and the phase-compensated liquid crystal layer and is reflected to go through again the phase-compensated liquid crystal layer in a direction perpendicular to a polarization direction of the linear polarizer. By providing a liquid crystal layer to achieve compensation for phase difference, the present application can overcome a problem of visual interference and glare effects brought about by the display panel due to external light.
