Abstract: A direct type backlight module includes a back plate, a light emitting element, and a frame body. The light emitting element is disposed on the back plate and configured to provide an illumination beam. The frame body is disposed on the back plate to surround the light emitting element. The frame body includes a light transmitting portion and a reflecting portion. The light transmitting portion is located at an edge of a light emitting side of the direct type backlight module. The reflecting portion is located between the light transmitting portion and the back plate. The light transmitting portion has a carrier portion, wherein the illumination beam is configured to be transmitted into the light transmitting portion, transmitted to the carrier portion of the light transmitting portion by reflection of the reflecting portion, and then emitted. A display device including the direct type backlight module is also provided.

Abstract: A reflective sheet includes a first reflective layer and a second reflective layer. The first reflective layer has a first index of refraction, and the second reflective layer has a second index of refraction. The first reflective layer and the second reflective layer are in contact with each other to form a contact interface, and the first index of refraction is different from the second index of refraction so as to make the contact interface be a reflective surface. A top surface of the first reflective layer opposite the contact interface serves as a light incident surface for the reflective sheet, the reflectance of the first reflective layer is larger than the reflectance of the second reflective layer, and the mechanical strength of the second reflective layer is larger than the mechanical strength of the first reflective layer.

Abstract: A light source module includes a light source, a light guide unit, an opaque reflective element, a reflective unit, and a patterned light-absorbing element. The light guide unit has first and second surfaces, a light incident surface, and third and fourth surfaces. A beam from the light source enters the light guide unit through the light incident surface and is transmitted to outside through the first surface. The opaque reflective element covers a portion of the first surface adjacent to the light incident surface. The patterned light-absorbing element is disposed on a surface of the reflective unit. A portion of the patterned light-absorbing element is between a portion of the third surface adjacent to the light incident surface and the reflective unit. Another portion of the patterned light-absorbing element is between a portion of the fourth surface adjacent to the light incident surface and the reflective unit.
