Abstract: A viewing angle controller, a display panel, and a display device. The viewing angle controller includes at least one liquid crystal controlling box. The liquid crystal controlling box includes a first liquid crystal controlling box including a first substrate, a second substrate, and a first liquid crystal layer arranged between the first substrate and the second substrate. The first liquid crystal controlling box operates in a first state or in a second state. A transmittance of first light passing through the first liquid crystal controlling box in the second state is lower than one or both of a transmittance of the first light in the first state and a transmittance of second light passing through the first liquid crystal controlling box in the second state. An inclination of the first light is greater than that of the second light relative to the front-viewing direction of the viewing angle controller.

Abstract: A display module, a display apparatus, and a vehicle are provided. The display module includes a backlight component, and a display component located at a side of the backlight component facing toward a light-emitting direction of the display module. The backlight component includes a first light guide structure, a light regulating structure, and a polymer liquid crystal film. The first polarizer is located at a side of the polymer liquid crystal film facing away from the backlight component. The polymer liquid crystal film is located at a side of the light regulating structure facing away from the first light guide plate and includes a polymer liquid crystal layer, and an electrode layer located at each of at least one side of the polymer liquid crystal layer. The display module has a sharing mode where the electrode layer is not energized and an anti-peeping mode where the electrode layer is energized.

Abstract: Embodiments relate to a modified cell comprising a polynucleotide encoding an antigen binding molecule and a polynucleotide encoding an agent targeting one or more extracellular matrix (ECM) molecules. In embodiments, the polynucleotide encoding the agent comprises at least a nucleic acid encoding Cathepsin K (CK), a nucleic acid encoding Neutrophil Elastase (NE), or a nucleic acid encoding MMP7. In embodiments, the nucleic acid encoding NE comprises a nucleic acid encoding NE and a nucleic acid encoding a signaling domain of IL2. In embodiments, expression of the polynucleotide encoding the agent is regulated by hypoxia-inducible factor 1-alpha (HIF1?), nuclear factor of activated T-cells (NFAT), forkhead box P3 (FOXP3), or nuclear factor kappa B (NF-?B).

Abstract: A display module and a display apparatus. The display module includes a display panel and a first light control panel. The first light control panel includes a first base and a second base arranged opposite to each other and a first light control liquid crystal layer arranged between the first base and the second base. The first base includes a first substrate, a first electrode, a first alignment layer, and a first polarizer. The second base includes a second substrate, a second electrode, a second alignment layer, and a second polarizer. A polarization axis of the first polarizer is perpendicular to a polarization axis of the second polarizer. An alignment direction of the first alignment layer is parallel to an alignment direction of the second alignment layer. An angle between the alignment direction of the first alignment layer and the polarization axis of the first polarizer is ?, 90°>?>0°.
