Abstract: A display panel includes a display area and a frame area adjacent to the display area. The frame area includes a substrate, and a signal wiring, a planarization layer, a leading wiring, and an encapsulation layer sequentially disposed on the substrate, and the encapsulation layer includes a first inorganic layer disposed on the leading wiring. The display area includes the substrate, the planarization layer, and an anode disposed on a side of the planarization layer away from the substrate, and the leading wiring extends from the side of the anode to the frame area and is connected to the signal wiring. The display panel further includes a barrier layer disposed between the leading wiring and the first inorganic layer, and an orthographic projection of the barrier layer on the substrate covers an orthographic projection of the leading wiring on the substrate.

Abstract: A flexible display panel is provided, which includes a base substrate, a thin film transistor (TFT) array layer, and an encapsulation layer. The TFT array layer includes an inorganic layer. An organic layer is disposed on the TFT array layer in a non-display region. The organic layer is defined with a hollow structure at least penetrating the organic layer and the encapsulation layer covers the hollow structure. The organic layer includes a planarization layer, a pixel definition layer, and a support layer. The hollow structure includes grooves with different groove levels, which improves a bending resistance of the flexible display panel and prevents cracks from extending to a display region.

Abstract: The present invention belongs to the technical field of analysis and detection and provides a method for detecting a selenoamino acid in a selenoprotein. The detection method includes: (1): mixing 10-30 mg of a selenoprotein sample with hydrochloric acid, and hydrolyzing with microwaves at 140-170° C. for 10-40 min to obtain a hydrolysate; (2): adjusting pH of the hydrolysate to 6-8 to obtain a pretreated solution; and, (3): detecting a selenoamino acid in the pretreated solution with high performance liquid chromatography-hydride generation-atomic fluorescence spectrometry (HPLC-HG-AFS) to obtain a content of the selenoamino acid. The method is simple in operation and provides an accurate and reliable result, and also reduces time and cost.

Abstract: A display panel, a mask, and a display device are provided. The display panel includes a substrate, a first flexible layer, a first inorganic layer, and a second inorganic layer stacked from bottom to top. A crack blocking structure is disposed on the first flexible layer, and the crack blocking structure includes a cutting portion and a concave portion located at two sides of the cutting portion. The first inorganic layer and the second inorganic layer are disconnected at an opening of the concave portion. The concave portion is configured to block cracks of the first inorganic layer and the second inorganic layer from extending to two sides of the crack blocking structure when the cutting portion cuts the display panel.

Abstract: A flexible packaging structure and a flexible display panel are disclosed. The flexible packaging structure of the present application adds an additional organic layer over an original organic layer at a position of a non-display area corresponding to the flexible display panel, thereby enhancing a coverage of contaminant particles in the non-display area and improving a packaging yield. In addition, the flexible packaging structure does not add the organic layer at a position corresponding to a bending area of the flexible display panel. An inorganic layer is directly deposited on the original organic layer, so that a groove structure is formed in the bending area of the flexible packaging structure, thereby improving bending performance.
