A curved surface backlight unit, a display device and a manufacturing method. The curved surface backlight unit includes a light guide plate and one or more arc-shaped positioning members; the light guide plate is a curved light guide plate formed by extending from its middle position to both sides along the first direction, including an inner arc surface and an outer arc surface; The second direction perpendicular to the first direction in the plane of the inner arc surface and the outer arc surface of the light guide plate is a straight line direction; at least the middle position of the light guide plate and each side of the middle position At least one position is fixedly connected to at least one arc structure of the arc positioning member, and the arc bending direction of the light guide plate is consistent with the bending direction of the arc structure of the arc positioning member.
Description
technical field [0001] The invention relates to the technical field of curved surface display, in particular to a curved surface backlight unit, a preparation method thereof and a display device comprising the curved surface backlight unit. Background technique [0002] Curved display has the advantages of low screen reflection and high contrast. At present, curved surface display technology is more and more widely used in fields such as monitors and large-screen TVs. The design and molding of the curved backlight unit in the curved display is relatively difficult, and it is also the key to the production of the curved display. In the prior art, the curved surface backlight unit is produced by first forming the curved surface backlight unit monomers, and then assembling the individual monomers, which is not only complicated in process, but also high in cost. Contents of the invention [0003] One aspect of the present invention provides a curved backlight unit, including...
