  • Publication number: 20240107606
    Abstract: Provided in the embodiments of the present application are a wireless communication method and device. For NSTR characteristics of a mobile AP MLD, it is designed that uplink simultaneous transmission between a plurality of independent non-access-point devices is triggered in a mobile AP MLD scenario. By means of the embodiments of the present application, an uplink access restriction is relaxed, and under the condition of not affecting the transmission quality of a single-link device on a main link, the success rate of uplink simultaneous transmission between mobile AP MLDs is increased, and a transmission service having a high throughput is also provided.

  • Publication number: 20240093345
    Abstract: The present disclosure provides a fixed-position defect doping method for a micro-nanostructure based on a self-alignment process, including: S1, sequentially forming a sacrificial layer and a photoresist layer on a surface of a crystal substrate; S2, performing a lithography on the photoresist layer to form a mask hole according to a micro-nano pattern; S3, performing an isotropic etching on the sacrificial layer through the mask hole, and amplifying the micro-nano pattern to the sacrificial layer; S4, performing an ion implantation doping on an exposed crystal surface below the mask hole; S5, removing the photoresist layer, and depositing a mask material; S6, removing the sacrificial layer, and transferring a micro-nano amplified pattern in the sacrificial layer to a mask material pattern; and S7, etching an exposed crystal surface, and removing the mask material on the surface and forming a specific defect by annealing.

  • Patent number: 10216038
    Abstract: The present invention relates to the display technology field, and provides a backplate, a plastic-iron integrated structure, a backlight unit, and a display device. The backplate is provided with a first through hole, and the first through hole has an inner wall and an outer wall which form a projection structure on the backplate. When the backplate is bonded with a plastic frame to form the plastic-iron integrated structure, the plastic frame not only contacts the inner wall of the first through hole, but also contacts the surface of the projection structure, thus increasing the contact area between the plastic frame and the backplate, and increasing the bonding force between the plastic frame and the backplate. Even when the plastic frame shrinks in case of fluctuations in temperature and/or humidity, the plastic frame is not easily separated from the backplate, and the stability of the formed plastic-iron integrated structure is improved.

  • Publication number: 20180249145
    Abstract: Automultiscopic displays enable glasses-free 3D viewing by providing both binocular and motion parallax. Within the display field of view, different images are observed depending on the viewing direction. When moving outside the field of view, the observed images may repeat. Light fields produced by lenticular and parallax-barrier automultiscopic displays may have repetitive structure with significant discontinuities between the fields of view. This repetitive structure induces visual artifacts in the form of view discontinuities, depth reversals, and extensive disparities. To overcome this problem, a method modifies the presented light field automultiscopic image content and makes it more repetitive. In the method, a light field is refined using global and local shearing and then the repeating fragments are stitched. The method reduces the discontinuities in the displayed light field and leads to visual quality improvements.
