Abstract

The embodiment of the invention provides a backlight module, a manufacturing method thereof and a display device, and relates to the technical field of display. The backlight module can reduce the probability of relative displacement of part of optical films. The backlight module comprises a composite layer, and the composite layer comprises a light guide layer and a first substrate which are oppositely arranged, and a plurality of first microprisms and a plurality of second microprisms which are located between the light guide layer and the first substrate. The multiple first microprisms arelocated on the surface of the side, close to the first substrate, of the light guide layer, and the extending directions of the multiple first microprisms are all parallel to the first direction. Thesecond microprisms are located on the surface of the side, close to the light guide layer, of the first substrate, and the extending directions of the second microprisms are parallel to the second direction. And the first microprism is fixedly connected with the second microprism.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module, a manufacturing method thereof, and a display device. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, thin film transistor-liquid crystal display device), as a flat panel display device, has become more and more popular because of its small size, low power consumption, no radiation and relatively low production cost. It is widely used in the field of high-performance display. [0003] The TFT-LCD has a backlight module (Back Light Unit, BLU) for providing backlight to the display panel. The backlight module includes multiple optical films stacked in layers. When the display device is in use, tested or transported, some optical films will be relatively displaced, resulting in wrinkles, resulting in defects such as Newton rings and moiré patterns in the displayed image. .
