Abstract

The application discloses a backlight module, a preparation method thereof, and a display device. The backlight module includes an array substrate and a plurality of light emitting devices arranged on the array substrate, the array substrate includes: a base substrate, and a first metal layer and a second metal layer arranged on the base substrate two metal layers; a planar layer covering the first metal layer and the second metal layer and exposing a portion of the first metal layer and a portion of the second metal layer; and, a metal stack, The portion of the first metal layer and the portion of the second metal layer that are disposed on the flat layer and contact the exposed flat layer; the metal stack includes at least one layer of the first metal, at least one layer a second metal and at least one layer of metal oxide, and the first metal is molybdenum. The second metal has high reflectivity and better conductivity than the metal oxide, which can effectively reduce light loss and achieve better conductivity.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a backlight module, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, Micro-LED (Micro-Light Emitting Diode, miniature light-emitting diode) has developed into one of the hot spots of future display technology, and the current LCD (Liquid Crystal Display, liquid crystal display), OLED (Organic Light Emitting Diode, organic Compared with light-emitting diode) display devices, it has the advantages of fast response, high color gamut, high PPI (Pixels Per Inch, pixel density), low energy consumption, etc.; but its technical difficulties are many and complex, especially its key technology mass transfer technology , LED (Light Emitting Diode, light-emitting diode) particle miniaturization has become a technical bottleneck, and Mini-LED (Mini-Light Emitting Diode, mini light-emitting diode), as the...
