Abstract: Provided are a set and a display device. The set includes a display module including a display panel, a module mold frame, a front housing and a backplane. At least part of front housing is located on a light-emitting side of display panel and is disposed opposite to at least one side edge of module mold frame; front housing is provided with first and second connecting structures, the module mold frame has a first module mold frame side edge where a third connecting structure is disposed, the backplane of display module is provided with a fourth connecting structure. First and third connecting structures cooperate to limit the position of front housing in a plane parallel to a light-emitting surface of display module; second and fourth connecting structures cooperate to limit the position of front housing in a direction perpendicular to light-emitting surface.

Abstract: A front light source and a display device are disclosed, and the front light source includes a housing extending along a first direction, and a side wall of the housing having an opening extending along the first direction; a supporting frame, located inside the housing and extending along the first direction, where the supporting frame includes a supporting surface; a light bar, where the light bar extends along the first direction and is attached to the supporting surface; and a side of the light bar far away from the supporting surface has a plurality of light-emitting units arranged along the first direction; a polarizing lens located between the light bar and the opening and extending along the first direction; where the polarizing lens includes: a light incident surface, a light exiting surface, a first reflective curved surface and a second reflective curved surface, extending along the first direction.

Abstract: The present disclosure provides a curvature determination method, a curved display panel, and a display device. The curvature determination method includes: establishing a first association relationship between deflection and a shear stress of the curved display panel in a first direction, the first direction being a bending direction of the curved display panel; determining a constraint condition for the shear stress in accordance with an influence of the shear stress on a light leakage of the curved display panel; and generating a curvature change relationship of the curved display panel in the first direction in accordance with the first association relationship when the constraint condition has been satisfied.
