Abstract: An anti-peep light source module and an anti-peep display device having an anti-peep function and good image quality are provided. The anti-peep light source module includes a light guide plate, a first light emitting element, a second light emitting element, a plurality of optical microstructures and a first surface. The light guide plate has a first light incident surface and a second light incident surface. Each of the optical microstructures has a first optical surface facing the first light incident surface and a second optical surface facing the second light incident surface. A magnitude of a first included angle between the first optical surface and the first surface and a magnitude of a second included angle between the second optical surface and the first surface gradually change as getting farther away from the first surface.

Abstract: A light guide module and a light source module are provided. The light guide module includes a light guide plate (LGP) and a first reflective component. The LGP includes a plate body and first microstructures. The plate body has a first light incident surface, a first side surface and a first surface connected thereto. The first microstructures are located on the first surface, and each of the first microstructures has a first optical surface facing the first side surface and the first microstructures are arranged in a first microstructure pattern. The first reflective component is located beside the first side surface, wherein the first microstructures are adapted to cause a light beam reflected by the first reflective component to present a first pattern through the first optical surfaces.

Abstract: A light source module includes a light source and a reflective element. The light source has a light emitting surface. The reflective element is disposed on a transmission path of an illumination light beam emitted from the light source. The illumination light beam reflected by the reflective element is irradiated on a target plane. The reflective element includes a first reflective surface and a second reflective surface. The first reflective surface is disposed towards the light emitting surface of the light source, and is a plane. The second reflective surface bendably extends from the first reflective surface.

Abstract: The invention provides a light source module including a light guide plate and light emitting elements. The light guide plate includes a main plate body and a plurality of optical microstructures. The main plate body has a light emitting surface and a back surface opposite to each other, and a light incident surface connected therebetween. The optical microstructures are formed on the back surface. Each optical microstructure includes at least two sections connected to each other, each section having a reflective surface. The light emitting elements are disposed on the light incident surface, and light emitted by each of the light emitting elements is reflected by at least some of the reflective surfaces and transmitted to the light emitting surface. In any optical microstructure, the reflective surfaces are not parallel to each other.

Abstract: A multi-screen display device includes a plurality of display screens and a prism structure optical element disposed between two adjacent display screens. The prism structure optical element includes a substrate and a plurality of prism columns. The substrate includes a first region and a second region adjacent to each other, and the lengths of the first and second regions are respectively La and Lb, and La≥Lb. The prism columns include a plurality of first and second prism columns in the first and second regions respectively. Each first prism columns has two interior angles θa1, θa2, a first surface and a second surface. Each second prism columns has two interior angles θb1, θb2, a third surface and a fourth surface. The second and/or fourth surfaces are light absorbing surfaces, or a roughness of the second and fourth surfaces is greater than that of the first and third surfaces.
