Abstract: A backlight module includes a substrate, light-emitting elements, circuit elements and a reflective sheet. The light-emitting elements are bonded onto the substrate. The circuit elements are bonded onto the substrate and electrically connected to the light-emitting elements. At least four of the light-emitting elements are disposed around one of the circuit elements. The reflective sheet is disposed on the substrate and has first openings exposing the light-emitting elements and protrusions. The protrusions corresponds to the circuit elements and cover the circuit elements. One of the protrusions has an opening formed of two crossing slits. Extending directions of the two crossing slits do not cross the at least four of the light-emitting elements. The one of the protrusions corresponds to the one of the circuit elements. The at least four of the light-emitting elements are closer to the one of the circuit elements than other of the light-emitting elements.

Abstract: The disclosure provides a backlight module and a display device. The backlight module includes a substrate, a light-emitting element, a circuit element, and a reflective sheet. The light-emitting element is bonded onto the substrate. The circuit element is bonded onto the substrate and electrically connected to the light-emitting element. The reflective sheet is disposed on the substrate and has a first opening. The first opening at least exposes the light-emitting element. At least a portion of a surface of the circuit element is made reflective. The display device includes the backlight module and a display panel disposed on the backlight module. The backlight module and the display device of the embodiment of the disclosure may improve the mura or exhibit a more uniform brightness.

Abstract: The disclosure provides an optical device including a diffusion layer, a light-emitting device, and a first photoluminescent film. The diffusion layer is disposed opposite to the light-emitting device, and the light-emitting device includes a plurality of light-emitting units. The first photoluminescent film is between the diffusion layer and the light-emitting device. A first distance between the first photoluminescent film and the diffusion layer is greater than a second distance between the first photoluminescent film and one of the plurality of light-emitting units. The optical device of the disclosure may improve brightness efficiency.
