Abstract

The invention provides a backlight module and a display device. The backlight module comprises: a plurality of lamp panels which are spliced with one another; and light reflecting pieces which are arranged corresponding to the splicing seams of the two adjacent lamp panels. By arranging the light reflecting pieces at the splicing seam of every two adjacent lamp panels, the reflecting effect of light at the splicing seam is improved, and the shadow problem at the splicing seam is solved.

Description

technical field

[0001] The present application relates to the field of display technology, in particular to a backlight module and a display device. Background technique

[0002] At present, for large-sized sub-millimeter light-emitting diode (mini-LED) backlight modules in vehicles, the light boards of sub-millimeter light-emitting diode backlight modules usually use spliced ​​light boards, that is, multiple light boards are spliced ​​into a whole lamp. board as a backlight. Due to the limitation of the light path propagation path of the direct-type backlight, when the large-size sub-millimeter light-emitting diode backlight module adopts the panel design, the treatment of the seam generated by the splicing between two adjacent light panels is currently encountered. One problem is that due to the existence of the seam, the light of the direct-lit backlight at the splicing position is relatively dark, which appears as a dark shadow or dark area optically on the product, whi...
