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.

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.

Abstract: An optical assembly, a vehicle lamp and a motor vehicle are disclosed. The optical assembly includes a light guide, the light guide at least having a first light guide section, a second light guide section and a bridging light guide section. The first light guide section and the second light guide section are connected together at one end to form an end region and bifurcating from the end region, the end region having an end face for the in-coupling of light. The bridging light guide section is arranged between the first light guide section and the second light guide section. The bridging light guide section is spaced apart from a bifurcation position of the first light guide section and the second light guide section, and the bridging light guide section has a light in-coupling face facing the bifurcation position, and a light out-coupling face.

Abstract: The present utility model discloses a light guiding device and a vehicle lamp. The light guiding device includes a light guide medium component configured to allow light to be transmitted through it from one end thereof to another end thereof. A light guide fixing component is arranged on the light guide medium component and configured to fix the light guide medium component, wherein the light guide medium component and the light guide fixing component are both at least partly made of a transparent material. The light guide fixing component has a light directing portion configured to direct the light leaked from the light guide medium component into the light guide fixing component to exit the light guide fixing component away from a predetermined direction. Using the light guiding device and the vehicle lamp according to the present utility model can prevent light exiting the light guide fixing component from forming undesirable light spots in an undesirable direction.
