Abstract: An electronic device includes a backlight module. The backlight module includes a light guide plate and a light pattern adjustment component disposed on the light guide plate. The side of the light pattern adjustment component that is adjacent to the light guide plate has a plurality of prismatic structures, and the side of the light pattern adjustment component that is away from the light guide plate has a plurality of structural unit rows. Each of the structural unit rows includes a plurality of structural units, and the angle between the arrangement direction of the structural units in one of the structural unit rows and the extension direction of one of the prismatic structures is within a range of 10-80°.

Abstract: An electronic device includes a substrate, a plurality of first retaining walls, a second retaining wall, and a light emitting element. The first retaining walls are arranged on the substrate. The second retaining wall is arranged on the substrate and disposed within one of the first retaining walls. The light emitting element is arranged on the substrate and disposed between the second retaining wall and one of the first retaining walls adjacent to the second retaining wall. In a cross section, there are a first distance between the light emitting element and the one of the first retaining walls, and a second distance between the light emitting element and the second retaining wall, wherein the second distance is smaller than the first distance.

Abstract: A backlight module includes a substrate, a plurality of light emitting elements, a light guide device and a plurality of reflective elements. The light emitting elements are arranged on the substrate. The light guide device includes a plurality of light guide portions arranged to respectively correspond to the light emitting elements, wherein each of the light guide portions is provided with a first through hole, and the first through holes of the light guide portions respectively expose the light emitting elements. The reflective elements are respectively arranged on the light emitting elements, wherein, in a normal direction of the substrate, the reflective elements respectively overlap with the first through holes of the light guide portions.
