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 method for manufacturing a light guide plate (LGP) positioning block thereof includes providing a positioning block body of a LGP positioning block and filling and sealing a liquid in a receiving compartment formed in the interior of the positioning block body. The liquid is expandable with a drop of temperature so as to increase a volume thereof and thus enlarge a size of the positioning block body through elasticity of the positioning block body. In this way, the LGP positioning block is adjustable with the variation of the surrounding temperature so as to achieve effective positioning of the light guide plate and providing high reliability of a liquid crystal display device including the light guide plate.

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.

Abstract: A backlight module and a method of manufacturing the backlight module are disclosed. The backlight module includes a substrate including a first end and a second end opposite to the first end. An ink layer is disposed on the substrate and has a reflectivity gradually increasing from the first end to the second end. At least two of light-emitting units are arranged in an array on the ink layer.
