Disclosed are a backlight module and a display device. The backlight module includes: a driving backplate; and an optical film disposed on a side of the driving backplate light taking-off. The driving backplate includes a substrate, a plurality of electronic elements and an adhesive layer. The plurality of electronic elements are disposed on a side of the substrate close to the optical film, and the adhesive layer is disposed on the plurality of electronic elements. The adhesive layer includes a plurality of first adhesive-dispensed portions arranged at intervals, the plurality of first adhesive-dispensed portions contact and support the optical film. At least one edge of a support region formed by every four adjacent ones of the plurality of first adhesive-dispensed portions is at an angle with a row direction or a column direction of the plurality of electronic elements.

Backlight modules and display devices

Disclosed are a backlight module and a display device. The backlight module includes a driving backplate and an optical film on a side of the driving backplate light taking-off. The driving backplate includes a substrate, electronic elements, and an adhesive layer. The electronic elements are disposed on a side of the substrate close to the optical film. The adhesive layer covers the electronic elements and includes first adhesive-dispensed portions. The first adhesive-dispensed portions are in contact with the optical film.

A drive backplate and a display device are provided. The drive backplate includes a substrate, a wiring layer arranged on one side of the substrate, and a reflective layer. The reflective layer and the wiring layer are arranged on the same side of the substrate. The wiring layer includes at least one first type line, and the reflective layer covers the first type line. Each first type line includes at least one first recess, and the reflective layer is partially inside the first recess, so the present application increases a contact area between the reflective layer and the first type line, increases a bonding force between the reflective layer and the wiring layer, reduces a risk of detachment of the reflective layer from the wiring layer, and improves product quality of the display device having the drive backplate.
