Provided is a support bracket for supporting a diffuser, including: a support post and a mounting part arranged in a first direction. The mounting part includes: an elastic connection part and a base arranged opposite to each other along the first direction, the elastic connection part is connected to the base, the support post extends in the first direction and an end of the support post close to the mounting part is fixed to the elastic connection part, and the elastic connection part is configured to be elastically deformable in the first direction to change a distance between the end of the support post close to the mounting part and the base in the first direction. Further provided are a sub-backlight module, a display device and a splicing display module.

The present invention relates to a holding device (100) for a light source (200), comprising a first portion (110) and a second portion (120). The first portion and the second portion extend at least partly in a common plane. The second portion is movable relative to the first portion from a first position, before insertion of the light source, in which the first portion and the second portion form a slit (130) for receiving the light source, and to a least a second position, after insertion of the light source, in which the second portion clamps the light source in the slit. Further, a lighting assembly and a display unit comprising such a holding device and a light source is disclosed. The holding device comprises fewer parts and is easier to manufacture as compared to prior art devices.

Disclosed are a backlight module and a display apparatus. The backlight module includes an infrared light source, an optical fiber and a conversion component. The infrared light source is connected with an input end of the optical fiber and configured to provide infrared light to the input end of the optical fiber. An output end of the optical fiber is connected with the conversion component and configured to transmit the infrared light to the conversion component. The conversion component includes a tube body, and a plurality of light emitting elements are arranged along an extending direction of the tube body successively in the tube body. The light emitting elements are configured to emit visible light under the irradiation of the infrared light.

A lighting device includes light sources, a light source board, and a casing. The light source board includes a board body portion having a substantially circular outer edge where the light sources are arranged at intervals in a substantially annular shape such that each light source emits light toward a center, an extended portion extending inward from the board body portion, and a trace portion electrically connected to each light source. The casing includes a tubular-shaped side wall portion surrounding the light sources, and a bottom portion disposed opposite the board body portion and having an exit hole therethrough through which the extended portion is inserted and the distal end of the extended portion is extended outside.

The present disclosure relates to the field of display technologies, and discloses a light guide plate, a backlight module and a display device, for improving light exit uniformity of the light guide plate and reducing occurrence of phenomenons such as brightness non-uniformity and intersecting light beams of the display device. A plurality of first light-diffusing units is disposed on a light incident surface of the light guide plate. At least one light-diffusing structure is disposed in a set region within the light guide plate in a direction facing away from the light incident surface. In the light guide plate, by disposing a plurality of first light-diffusing units and at least one light-diffusing structure on the light incident surface, light emitted from a light source can be better diffused after passing through the light guide plate and become more uniform before entering the display panel.

A pixel electrode or a common electrode is a light-transmissive conductive film; therefore, it is formed of ITO conventionally. Accordingly, the number of manufacturing steps and masks, and manufacturing cost have been increased. An object of the present invention is to provide a semiconductor device, a liquid crystal display device, and an electronic appliance each having a wide viewing angle, leas numbers of manufacturing steps and masks, and low manufacturing cost compared with a conventional device. A semiconductor layer of a transistor, a pixel electrode, and a common elect rod of a liquid crystal element are formed in the same step.

Dynamic, color-changing surfaces have many applications including but not limited to displays, wearables, and active camouflage. Plasmonic nanostructures can fill this role with the advantages of ultra-small pixels, high reflectivity, and post-fabrication tuning through control of the surrounding media. However, while post-fabrication tuning have yet to cover a full red-green-blue (RGB) color basis set with a single nanostructure of singular dimensions, the present invention contemplates a novel LC-based apparatus and methods that enable such tuning and demonstrates a liquid crystal-plasmonic system that covers the full red/green/blue (RGB) color basis set, as a function only of voltage. This is accomplished through a surface morphology-induced, polarization dependent, plasmonic resonance and a combination of bulk and surface liquid crystal effects that manifest at different voltages. The resulting LC-plasmonic system provides an unprecedented color range for a single plasmonic nanostructure, eliminating the need for the three spatially static sub-pixels of current displays. The system's compatibility with existing LCD technology is possible by integrating it with a commercially available thin-film-transistor (TFT) array. The imprinted surface readily interfaces with computers to display images as well as video.

One end of the vertical portion is inserted into the second groove. The rear cover includes a body covering a back surface of the horizontal portion, and a hook protruding from the body in the first direction and inserted into the first groove.
