  • Publication number: 20220221758
    Abstract: A display apparatus, comprising: a plurality of light sources arranged into an array, angle selection sheets on the light emitting sides of the light sources, and reflective layers on the sides of the light sources away from the angle selection sheets. The angle selection sheets are used for reflecting light rays of a first incident angle range and transmitting light rays of a second incident angle range, wherein an incident angle value corresponding to the first incident angle range is smaller than an incident angle value corresponding to the second incident angle range. The reflective layers can conduct diffuse reflection on the light rays reflected by the angle selection sheets and the light rays re-enter the angle selection sheets, so that light rays of a second incident angle subjected to the diffuse reflection are transmitted while light rays of a first incident angle repeat the described reflection operation.

  • Patent number: 11374411
    Abstract: The invention relates to an island converter overload limit method and device for a bipolar flexible DC transmission system, and belongs to the field of DC transmission. During stable island operation, both bipolar converters adopt a voltage-frequency droop control strategy; and once it is detected that one converter is overloaded, the control mode of the overloaded converter is automatically switched to active-wattless power control from voltage-frequency droop control to fulfill an overload limit function. The method effectively avoids an overload of the bipolar flexible DC transmission system under island operation, effectively maintains the AC voltage and frequency stable, and has important guiding significance for applying island systems to DC power grids.
