Abstract

The invention discloses a backlight module, a preparation method of the backlight module and a display device. The backlight module comprises a back plate, a plurality of lamp panels and a first reflector plate. Wherein the plurality of lamp panels are spliced and fixed on the back plate, and a splicing seam is formed between every two adjacent lamp panels; the first reflector plate is arranged in the abutted seam to reflect light irradiated to the abutted seam by the lamp panel; each lamp panel comprises a substrate, a plurality of light-emitting chips and a packaging layer; the plurality of light-emitting chips are arranged on one side of the substrate; the packaging layer is arranged on one side of the substrate, the orthographic projection of the packaging layer on the substrate completely covers the substrate, the packaging layer covers each light-emitting chip, the packaging layer can conduct light emitted by the light-emitting chips, and the side, close to the abutted seam, of the packaging layer is a cambered surface. According to the embodiment of the invention, the problem that the brightness at the splicing seam is relatively dark can be solved, and the brightness at the splicing seam can be prevented from being too bright, so that the problem that the display brightness of the backlight module is not uniform is solved, and the display effect of the display device is ensured.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular, relates to a backlight module, a preparation method thereof, and a display device. Background technique [0002] With the rapid progress of liquid crystal display production technology and its advantages of lightness, thinness, power saving and no radiation, liquid crystal displays are widely used in notebook computers, digital cameras, digital camcorders, mobile phones, computer screens and liquid crystal displays. TVs and other electronic products. However, since the liquid crystal display panel in the liquid crystal display is a non-self-luminous display panel, the display function can only be generated by the light source provided by the backlight module. [0003] In the related art, the current LCD TV backlight module is formed by splicing a plurality of lamp panels. Since the lamp panels will generate a certain expansion due to heat during operation, an expans...
