Abstract: A backlight module and a display device are provided. The backlight module includes a light-emitting substrate and a reflective film layer disposed on a light-exiting surface of the light-emitting substrate. The light-emitting substrate includes a base substrate and light-emitting elements and light-scattering members disposed on one same surface of the base substrate. The reflective film layer includes a plurality of light-exiting holes for light passing through. A part of the light emitted by the light-emitting elements is reflected to the light-scattering members by the reflective film layer and is scattered by the light-scattering members. Therefore, light intensity of regions between the light-emitting elements is enhanced.

Abstract: A die-bonding method and a spraying device for an LED include: providing a substrate provided with a pad and a white oil layer covering wiring, placing a steel mesh on the substrate, and then spraying suspension containing solder paste on the pad by the spraying device, to form a solder paste film layer. Finally, a reflow process for the solder is performed. The solder paste is prepared on the pad by spraying, so that a crystal wafer is prevented from being tilted or short-circuited due to pulling or dragging of the solder paste during the reflow process for the solder, thereby improving uneven brightness of the surface light source.
