The present application provides a comfortable lightweight bullet-proof and stab-resistant suit and a preparation method thereof. A first aspect of the present application provides a comfortable lightweight bullet-proof and stab-resistant suit, including a sheath and a protection core sheet disposed in the sheath, and the protection core sheet includes a first protection layer, a second protection layer, a third protection layer and a buffer layer which are sequentially stacked together. The bullet-proof and stab-resistant suit provided in the present application has better response protection characteristics in the process of bullet penetration or knife tip stab, and the prepared aramid unidirectional cloth has low areal density, apparent flatness, no bubbles, and excellent softness, so that any bending within 180° can be realized.

Comfortable lightweight bullet-proof and stab-resistant suit and preparation method thereof

A quick-release assembly includes an installation main body and a quick-release clamping plate, the installation main body is provided with a groove structure, the groove structure is provided with a first clamping hole and a second clamping hole that are oppositely arranged, and a portion of the second clamping hole is located on a side wall of the groove structure; the quick-release clamping plate matches the groove structure, and a first clamping hook and a second clamping hook are provided on the quick-release clamping plate; the installation main body is provided with a sliding block installed on the installation main body in a sliding manner; an elastic member for providing a driving force for the sliding block is also arranged in the installation main body; and a quick-release button for releasing a locking state of the sliding block is also arranged in the installation main body.

Quick-release assembly and virtual reality device

A curved optical plate includes a curved light exit surface including at least one curved edge and at least one uncurved edge, and at least one first side surface connected to the at least one uncurved edge of the light exit surface; a first side surface includes a first surface, and the first surface extends toward an interior of the curved optical plate.

Curved optical plate and method of manufacturing the same, backlight module and display device

A display device and a control method therefor are disclosed. The display device includes: a first backlight module; a second backlight module located at a light emergent side of the first backlight module; and a display panel located at a side of the second backlight module facing away from the first backlight module; where the first backlight module includes a first light board, and the first light board emits light to a side of the second backlight module; the second backlight module includes at least one second light board, second light boards of the at least one second light board are stacked, and the second light boards transmit the light emitted by the first backlight module and emit light to the display panel; the first light board includes a plurality of first light sources, each second light board of the second light boards includes a plurality of second light sources.

Display device and control method therefor

A display module includes a back plate, a light guide plate, a rubber frame and a display panel, the light guide plate is fixed on a bearing surface, a connecting line between two end portions of the bearing surface forms a first curve. The first curve includes a circular arc segment and a transition curve segment, and bends in a direction away from the display panel; the circular arc segment is located at the middle, at least one end of the circular arc segment is provided with the transition curve segment; the transition curve segment is located at a first position, the first position being a position of the bearing surface opposite to a second position, the second position being a position where light leaks from the display panel, the radius of curvature of the transition curve increases along a direction close to an end portion of the first curve.

Display module, display device and calculation method

A dimming assembly includes a first prism having a first surface and a second surface opposite to each other, and a second prism disposed on a side where the second surface of the first prism is located. The first surface includes first dimming portions, each of which includes two first side surfaces. Edges of the two first side surfaces away from the second surface intersect at a first intersection line. A surface of the second prism proximate to the second surface includes second dimming portions, each of which includes two second side surfaces. Edges of the two second side surfaces proximate to the second surface intersect at a second intersection line. A distance between orthographic projections of two adjacent first intersection lines on the second surface is less than a distance between orthographic projections of two adjacent second intersection lines on the second surface.
