Abstract: A glitter module and an electronic product are provided. The glitter module includes a base material and a reflective graphic located on a surface of the base material. The reflective graphic includes multiple first-level regions. Each first-level region has multiple second-level regions. The second-level region is provided with a plurality of strip-shaped grooves. Each first-level region has a specified direction. An angle between an extension direction of a strip-shaped groove of a plurality of second-level regions in a same first-level region and a specified direction of a corresponding first-level region ranges from −20° to 20°. Along a preset direction of the reflective graphic, angles between specified directions of the plurality of first-level regions and the preset direction are in a gradient change relationship.

Abstract: A decorative substrate includes a base material and multiple texture units sequentially arranged in a first direction. Each texture unit includes a protruding part. The cross section of the protruding part in a third direction transitions from an arc segment to a straight line segment in a second direction. The second direction is perpendicular to the first direction, and the third direction is perpendicular to the first direction and the second direction. The highest points of the cross section of the protruding part in the third direction meet at least one of the following relationships: the distance between the highest points and the surface of the base material changes in the second direction; or the connecting line between the orthographic projections of the highest points on the base material is an arc segment or a straight line segment, the straight line segment being not parallel to the second direction.
