Abstract: Disclosed are a viewing angle adjustment film structure, a manufacturing method thereof, and a display device, including a base, an isotropic optical material layer, and a liquid crystal layer stacked in sequence. The isotropic optical material layer is provided with grooves, the liquid crystal layer fills the grooves, and light enters from the liquid crystal layer and then exits through the isotropic optical material layer. Director of liquid crystal molecules in the liquid crystal layer is changed according to an external applied voltage or a change of an electric field, so as to adjust a viewing angle of the light emitted from the isotropic optical material layer.

Abstract: The present invention provides a viewing angle diffuser film and a display panel, including a base substrate and refractive protrusions. By setting space ratios of adjacent refractive protrusions in a first direction and a second direction, refraction directions of the viewing angle diffuser film can be controlled, and therefore light diffusion effects can be controlled. In the display panel of the present invention, the space ratios of the refractive protrusions in different directions are adjusted according to different usage scenarios to improve display brightness and reduce color shifts.

Abstract: A method for manufacturing a light guide plate (LGP) positioning block thereof includes providing a positioning block body of a LGP positioning block and filling and sealing a liquid in a receiving compartment formed in the interior of the positioning block body. The liquid is expandable with a drop of temperature so as to increase a volume thereof and thus enlarge a size of the positioning block body through elasticity of the positioning block body. In this way, the LGP positioning block is adjustable with the variation of the surrounding temperature so as to achieve effective positioning of the light guide plate and providing high reliability of a liquid crystal display device including the light guide plate.
