Abstract
The present disclosure provides a backlight module and a display device. The backlight module includes a substrate, mini LEDs, and at least one conductive reflective layer. The substrate includes a light-emitting area and a non-light-emitting area surrounding the light-emitting area. The mini LEDs are disposed in the light-emitting area of the substrate. The conductive reflective layer covers the whole non-light-emitting area, and the mini LEDs are electrically connected to one conductive reflective layer.
Claims9
A backlight module, comprising:
- a substrate comprising a light-emitting area and a non-light-emitting area surrounding the light-emitting area;
- a plurality of mini light-emitting diodes (LEDs) disposed in the light-emitting area of the substrate;
- and
- at least one conductive reflective layer covering whole non-light-emitting area, wherein the mini LEDs are electrically connected to the at least one conductive reflective layer;
- wherein the at least one conductive reflective layer comprises:
- a first conductive reflective layer disposed on the substrate;
