A light guide plate, a backlight module and a display device are provided. The light guide plate includes a main body, plural first strip structures and second strip structures. The main body includes a light incident surface, an end portion and a light guide portion. The end portion has at least one inclined surface. The light guide portion is connected to the end portion. The light guide portion has a first optical surface and a second optical surface. At least one portion of each of the first strip structures is disposed on the first optical surface. At least one portion of each of the second strip structures is disposed on the second optical surface. An inherent type, an arrangement manner or an arrangement position of the first strip structures is different from an inherent type, an arrangement manner or an arrangement position of the second strip structures.

Light guide plate, backlight module and display device

A light guide plate, a backlight module and a display device are provided. The light guide plate includes a main body, plural first stripe structures and plural second stripe structures. The main body has at least one light-incident surface and a main surface connected to the at least one light-incident surface. The first stripe structures are arranged on plural first regions of the main surface, in which each of the first stripe structures has a first tapered portion. The second stripe structures are arranged on a plurality of second regions of the main surface, in which each of the second stripe structures has a second tapered portion. The first areas and the second areas of the main surface are alternately disposed, and an inherent type of the second stripe structures is different from an inherent type of the first stripe structures.

A light guide plate, a backlight module and a display device are provided. The light guide plate includes a main body, first stripe microstructures, second stripe microstructures and third stripe microstructures. The main body includes a light incidence surface and an optic surface having a first area and a second area. The first area is disposed nearer the light incidence surface. The first stripe microstructures and the second stripe microstructures are respectively disposed on the first area and the second area. Each of the first stripe microstructures and the second stripe microstructures extends along the direction vertical to the light incidence surface. A width of one end of each second stripe microstructure near the light incidence surface is smaller than a width of the other end away from the light incidence surface. The third stripe microstructures are distributed on a partial or the whole region of the optic surface.

A light guide plate includes a main body and trapezoid-like structures. The main body includes a light-incident surface, a first main surface and a second main surface opposite to the first main surface. The trapezoid-like structures are disposed on at least one of the first main surface and the second main surface. The trapezoid-like structures extend along a direction from one side of the main body near the light-incident surface to the other side of the main body away from the light-incident surface. Each of the trapezoid-like structures has a width gradually increasing from one end of the trapezoid-like structure near the light-incident surface to the other end of the trapezoid-like structure away from the light-incident surface. Each of the trapezoid-like structures comprises a flat surface and two side surfaces, and the side surfaces are respectively connected to two sides of the flat surface.

Light guide plate

A light guide plate with multi-directional structures includes a main body, a plurality of first microstructures and a plurality of second microstructures. The main body includes a light-incident surface, a light-emitting surface and a reflecting surface. The light-incident surface connects the light-emitting surface and the reflecting surface. The first microstructures are disposed on the light-emitting surface or the reflecting surface and arranged along a first extending direction. The second microstructures are disposed on the light-emitting surface or the reflecting surface and arranged along a second extending direction. The second microstructures and the first microstructures are disposed on the same plane and intersect with each other. Each of the second microstructures is a single stripe pattern, and has a width which becomes gradually smaller from one end of the second microstructure near the light-incident surface to the other end of the second microstructure away from the light-incident surface.
