Abstract

The invention relates to the technical field of display, and provides a backlight module, a manufacturing method of the backlight module, and a display device. The backlight module comprises a liningsubstrate, a collimation layer and a plurality of light-emitting elements, wherein the collimation layer is arranged on one side of the lining substrate, a plurality of through holes are arranged in the collimation layer in an array distribution manner, and the inner side faces of the through holes can reflect light rays; and the plurality of light-emitting elements are arranged on the lining substrate and positioned in the through holes. For the backlight module provided by the invention, the lighting effect of the backlight module can be improved under the premise that the collimation is guaranteed, and meanwhile, the backlight module is simple in structure and easy to process.

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] With the rapid development of flat panel display technology, its display range and application scenarios are constantly expanding. The application scenarios of holographic display and light field display came into being. In this scenario, holographic display, light field and AR display can improve the dizziness caused by ordinary parallax 3D display and restore all the information of objects to a great extent. It is a future Show trends. The collimated backlight is a necessary condition and core technology of these stereoscopic display technologies. [0003] In related technologies, the collimated backlight module technology is generally divided into three categories: baffle shading, waveguide grating directional light collection and microlens collimation technology. [000...
