Abstract: A mini-LED backlight structure and a backlight module are provided. The mini-LED backlight structure includes a backplate, a glass substrate, and reflective sheets. The glass substrate includes a line surface and a lineless surface close to a side of the backplate. Light emitting diodes and a connector are disposed on the lineless surface. Furthermore, a gap is between the backplate and the glass substrate for disposing the light emitting diodes and the connector. The connector is electrically connected to an external circuit through a conducting wire. Disposing a plurality of elements, the connector, and the light emitting diodes on a same surface of the lineless surface is unlikely affecting backlight effect and saves materials at a same time.

Abstract: A display panel and a display device are provided. The display panel includes a driving backplate, a plurality of light-emitting diode (LED) chips disposed on a side of the driving backplate, and an adhesive. The adhesive includes a first state and a second state. Viscosity of the adhesive in the second state is less than viscosity of the adhesive in the first state. The driving backplate and the LED chips are fixedly connected to each other by the adhesive in the first state. The adhesive can be converted from the first state into the second state by laser irradiation, and power of the laser is less than 10 w. The driving backplate and the LED chips are attached to each other by the adhesive in the first state, and viscosity of the adhesive in the first state can be reduced by irradiation with a low-power laser.

Abstract: The embodiments of the present application provided a backlight module and a display panel. By disposing a reflective layer on the substrate and disposing vias, whose areas gradually decrease from the side close to an electric current input side to the side away from the electric current input side, on the reflective layer, the backlight module reduces the brightness of a light emitting device layer close to the electric current input side and increase the brightness of the light emitting device layer away from the electric current input side. Thus the brightness of both sides of the light emitting devise layer is uniform, and thus the backlight uniformity of the backlight module is increased.
