    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: A display device, including a display module and a peep-proof light source module, is provided. The display module is used to provide a display beam. The peep-proof light source module is disposed on a transmission path of the display beam and includes at least one light emitting element, a light guide plate, and optical microstructures. The light emitting element is used to provide a privacy light. The light guide plate has at least one light incident surface. Each optical microstructure has an optical surface facing the light incident surface. At least part of the privacy light is reflected by the optical surface and then exits the light guide plate. The distribution density of the optical microstructures on the light guide plate close to the light incident surface is substantially the same as the distribution density away from the light incident surface and close to the center.

    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: The invention provides a display device including a panel module, a reflection module and a light guide module. The panel module has a display area for displaying an image and a perspective area for displaying a background. The reflection module is disposed at a side of the panel module. A reflective sheet on the reflection module faces the panel module. The shape and position of the reflective sheet correspond to the shape and position of the display area, respectively. The light guide module includes a light guide plate and a light source. The light guide module is disposed between the panel module and the reflection module. The light guide plate has a plurality of optical microstructures, and light emitted by the light source is at least partially directed away from the panel module by the optical microstructures and is transmitted to the reflection module.
