  • Patent number: 12044376
    Abstract: A reflecting device includes at least one reflecting cavity corresponding to at least one light source. A first reflecting cavity located at an extremity of the reflecting device includes a first reflecting part, able to receive incident light from the light source corresponding to the first reflecting cavity, and reflect this light towards the second reflecting part. A second reflecting part adjoins the first reflecting part is able to reflect the reflected light from the first reflecting part towards the outside of the first reflecting cavity. The first reflecting cavity at the extremity of the reflecting device may include a first reflecting part and a second reflecting part, which are able to subject light rays from the light source to double reflection. This can considerably increase the design flexibility of the first reflecting cavity.

  • Patent number: 11862084
    Abstract: A pixel circuit, a driving method, a display substrate, and a display device are provided. The pixel circuit includes a driving circuit, a first light-emitting control circuit, a light-emitting element, a first initialization circuit, and a second initialization circuit. The first initialization circuit writes, under the control of a first initialization control signal, an initialization voltage provided by an initialization voltage line, to a control terminal of the driving circuit; the second initialization circuit writes, under the control of a second initialization control signal provided by a second initialization control line, an initial data voltage provided by an initial data line, to an anode of the light-emitting element. Light emission of the light-emitting element from a leakage current and lateral leakage at low gray scales caused when initializing the anode of the light-emitting element can be prevented.
