Embodiments of the present application provides a prism film, a light guide plate, a backlight module and a display apparatus. The prism film includes a sheet and an array of prisms arranged on a side of the sheet and vertex angles of the prisms in the array increase or decrease in magnitude sequentially from one end of the array of prisms to the other end of the array opposite to the one end.

Prism film, light guide plate, backlight module and display apparatus

A light guide plate, a fabricating method thereof, a backlight source, and a display device. The light guide plate comprises a light guide plate main body, with the surface of the light guide plate main body being provided with a blue coating. The blue coating mixes with yellow light strengthened gradually from a light entrance end to a light remote end of the light guide plate main body to form white light. The fabricating method of the light guide plate comprises: providing a light guide plate main body; forming a blue coating on a surface of the light guide plate main body; and curing the light guide plate main body provided with the blue coating. The present disclosure further provides a backlight source and a display device. The backlight source comprises the above light guide plate, and the display device comprises the above backlight source.

Light guide plate and fabricating method thereof, backlight source, display device

The present disclosure relates to the field of display technologies, and discloses a light guide plate, a backlight module and a display device, for improving light exit uniformity of the light guide plate and reducing occurrence of phenomenons such as brightness non-uniformity and intersecting light beams of the display device. A plurality of first light-diffusing units is disposed on a light incident surface of the light guide plate. At least one light-diffusing structure is disposed in a set region within the light guide plate in a direction facing away from the light incident surface. In the light guide plate, by disposing a plurality of first light-diffusing units and at least one light-diffusing structure on the light incident surface, light emitted from a light source can be better diffused after passing through the light guide plate and become more uniform before entering the display panel.

Light guide plate, backlight module and display device

The present invention relates to the technical field of display, and discloses a light guide plate, a backlight source and a display apparatus, for solving the problem of the exit light non-uniformity of the backlight source. The light guide plate comprises a light guide plate main body and at least one boss, the light guide plate main body comprises a first light entrance surface, a first light exit surface intersecting with the first light entrance surface, and a first bottom surface opposed to the first light exit surface; the boss is located on the first light entrance surface and comprises a second bottom surface adjoining the first light entrance surface, a top surface opposed to the second bottom surface, as well as two end faces and two side surfaces respectively intersecting with the top surface and the second bottom surface at two ends, wherein the area of the top surface is less than that of the second bottom surface, the two end faces are respectively flush with the first bottom surface and the first light exit surface, and the two side surfaces are respectively slope surfaces which may be used as a second light entrance surface. The light guide plate mentioned by the present invention is used to improve the exit light uniformity of the backlight source.
