US 2017/0285391 A1 · CURVED BACKLIGHT UNIT, MANUFACTURING METHOD THEREOF AND DISPLAY DEVICE

Abstract

A curved backlight unit, a display device and a manufacturing method are disclosed. The curved backlight unit includes a light guide plate (LGP), one or more cambered positioning pieces. The LGP is a curved LGP formed by extending from a center position of the LGP to both sides along a first direction and includes an inner cambered surface and an outer cambered surface. A second direction, perpendicular to the first direction, in the inner cambered surface or the outer cambered surface of the LGP is a linear direction. At least the center position of the LGP and at least one position on each side of the center portion are fixedly connected with a cambered structure of at least a same cambered positioning piece; and a bending direction of the cambered surfaces of the LGP is consistent with a bending direction of the cambered structure of the cambered positioning piece.

A curved backlight unit, comprising a light guide plate (LGP), one or more cambered positioning pieces, wherein the LGP is a curved LGP formed by extending from a center position of the LGP to both sides along a first direction and includes an inner cambered surface and an outer cambered surface;

a second direction, perpendicular to the first direction, in the inner cambered surface or the outer cambered surface of the LGP is a linear direction;
at least the center position of the LGP and at least one position on each side of the center portion are fixedly connected with a cambered structure of at least a same cambered positioning piece;
and a bending direction of the cambered surfaces of the LGP is consistent with a bending direction of the cambered structure of the cambered positioning piece.

A method for manufacturing a curved backlight unit, comprising:

providing a light guide plate (LGP) and cambered positioning pieces, wherein the LGP is a flat LGP and includes a first plane and a second plane which are opposite to each other, two side faces which are intersected with the first plane and the second plane and opposite to each other, and two end faces which are intersected with the first plane and the second plane and opposite to each other;
allowing the LGP to be bent, along a direction from the first plane to the second plane, to form an LGP with a curved structure in which the first plane becomes an inner cambered surface and the second plane becomes an outer cambered surface, and meanwhile, allowing the two end faces to be also bent into two cambered end faces;
and
fixing the LGP with the curved structure through the cambered positioning pieces, and obtaining a curved LGP.
