The utility model discloses a lamp outer frame has four first and last joint section bars, and the section bar is L type, and is formed by the bending of the sheet material, and the lower half portion end inner side portion of section bar is bent and forms the convex, compared with the scheme that diffuser plate is laid flat on the lower half portion inner side wall of section groove, the utility model is through the convex and props up diffuser plate, makes the opening end of the light -reflecting cover can extrude the circumference of diffuser plate downward, makes the middle portion of diffuser plate and is convex downward and even crosses the lower half portion inner side wall of section bar or even crosses the lower half portion of section bar, under the condition that the light -emitting distance of fixed light plate and diffuser plate is considered, makes the whole sinking of both, utilizes the space of the lower end opening of lamp outer frame, thereby reduces the occupation of diffuser plate thickness to lamp outer frame height space, so as to make section bar height or the height of lamp outer frame smaller, realizes the light and thin design of lamp.

This utility model belongs to the field of electronic technology and provides a notebook computer. To solve the problem of electrical connection between the chassis and display screen of a thin and light notebook computer, this utility model designs the notebook computer as a structure including a chassis, a display screen, and an electrical connection unit. The chassis has a first cable outlet; the display screen has a connecting part with hinged ends at both ends along the length of the display screen, which are hinged to the chassis; a second cable outlet is located between the two hinged ends and mates with the first cable outlet; the electrical connection unit passes through the first cable outlet and is electrically connected to the chassis, and passes through the second cable outlet and is electrically connected to the display screen. This design helps reduce the size of the connecting part, thus facilitating the thin and light design of the notebook computer.

This application provides a light filter, a display component, and an electronic device. The light filter includes a substrate and a filter stack located on one side of the substrate. The filter stack includes at least three stacked dielectric layer groups, each dielectric layer group consisting of one or more refractive dielectric layers. One of the refractive dielectric layers in at least one dielectric layer group includes a first refractive dielectric layer. The refractive index of the first refractive dielectric layer is greater than 1.1 and less than 1.35, or equal to 1.1, or equal to 1.35. The low refractive index of the first refractive dielectric layer can compensate for the transmittance and color purity of light incident at large angles. The dielectric layer groups in the filter stack constitute a Fabry-Perot cavity. Incident light of a specific wavelength band undergoes constructive interference in the Fabry-Perot cavity, increasing the transmittance of the incident light in that wavelength band. The filter provided by this application can increase the overall transmittance and color purity of incident light, thereby improving the brightness and color gamut of the electronic device and enhancing the display effect.
