Abstract

The embodiment of the invention provides a backlight module and a display panel, wherein the backlight module comprises a substrate, a reflection layer, a light-emitting device layer, and a packaginglayer; the substrate is provided with a plurality of bonding pads which are arranged in an array, the reflecting layer is arranged on the substrate, and via holes for exposing the bonding pad are formed in the reflecting layer; the light-emitting device layer is arranged on the reflecting layer and comprises a plurality of light-emitting devices, the light-emitting devices are electrically connected with the bonding pads through the via holes, the area of the via holes are in positive correlation with the brightness of the light-emitting devices, and the packaging layer is arranged on the light-emitting device layer. According to the scheme, the problem of uneven brightness of the backlight module can be solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a backlight module and a display panel. Background technique [0002] With the development of liquid crystal display panel technology, consumers have higher and higher requirements for image quality. Mini-Light Emitting Diode (Mini-Light Emitting Diode, MiniLED) backlight technology is a new type of backlight technology that can provide local light control for multiple partitions. , greatly improving the dynamic contrast of the liquid crystal display panel, thereby enhancing the consumer experience. [0003] At present, one of the MINI LED backlight implementation schemes is the AM-Mini-LED backlight module, which realizes lighting by voltage driving. Since there is a certain resistance in the power line of the light board, and the driving current of all pixels is provided by the power supply VDD, the power supply voltage in the area close to the power supply position...
