Problems solved by technology

[0003] In a traditional Mini LED backlight module, besides the LED array, other electronic devices are usually placed on the circuit surface of the substrate. Since other electronic devices will absorb light in the backlight, if the area occupied by other electronic devices is too large, shadows will be formed. Seriously affect the technical performance of Mini LED, and other electronic devices occupy too much area, making it impossible to place large components such as connectors
Therefore, the traditional Mini LED backlight module has the technical problem that connectors and other electronic components cannot be placed on different surfaces of the light board

Abstract

The invention relates to a backlight module and a display device with the backlight module. The backlight module is used for a Mini light emitting diode. The backlight module comprises a side edge wiring layer, the lamp panel comprises a circuit surface and a non-circuit surface which are opposite in position, the back plate is arranged adjacent to the non-circuit surface, a plurality of electronic devices are arranged on the non-circuit surface, a plurality of light-emitting element arrays are arranged on the circuit surface and electrically connected with the circuit surface, and the side edge wiring layer extends from the circuit surface to the non-circuit surface. The plurality of light-emitting elements and the plurality of electronic devices are electrically connected. According to the backlight module, the light-emitting element and the electronic device are arranged on the different surfaces of the lamp panel through the side edge wiring layer, meanwhile, the situation that shadows are formed on the lamp panel due to the fact that the electronic device absorbs light is avoided, and the optical uniformity, efficiency and use performance of the backlight module are improved.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a backlight module for Mini light-emitting diode (Light-Emitting Diode, LED) and a display device with the backlight module. Background technique [0002] In the technical development of liquid crystal display, the backlight module is an indispensable part. Among them, the advantages of Mini LED backlight technology are very obvious. Its ability to control the backlight area and reduce the optical distance of the backlight has been improved, thereby achieving high dynamic contrast, and has the significant advantage of weakening self-illumination technology. [0003] In a traditional Mini LED backlight module, besides the LED array, other electronic devices are usually placed on the circuit surface of the substrate. Since other electronic devices absorb light in the backlight, if the area occupied by other electronic devices is too large, shadows will be for...
