  • Publication number: 20250126965
    Abstract: The present disclosure provides an organic light-emitting diode, a display panel and a display device, relating to the field of display technologies. The organic light-emitting diode includes a first electrode, at least two emission layers, an optical modulation layer, and a second electrode. A thickness of the optical modulation layer has a relatively bigger range. Therefore, in the case that the thicknesses of other film layers between the first electrode and the second electrode vary, an optical modulation layer having a different thickness can be provided to adjust the microcavity length of the organic light-emitting diode, thereby ensuring the optical performance of the organic light-emitting diode and the display effect of the display panel.

  • Publication number: 20250049431
    Abstract: A tissue suturing device includes a body and a plurality of suture needles. The body includes a guide segment and a tube segment. The guide segment contains a suture needle channel. The tube segment has an accommodating cavity communicated with the suture needle channel. Each of the suture needles includes a main needle segment and a puncture needle segment connected with and spaced apart from the main needle segment. Two of the suture needles, together, connect a suture thread releasably between the puncture needle segments of the two suture needles. The main needle segments are arranged in the suture needle channel. The puncture needle segments carry the suture thread and are located in the accommodating cavity. Each of the suture needles moves along the suture needle channel such that the puncture needle segment returns to the accommodating cavity alone after passing with the suture thread through a tissue wall.
