Abstract

The invention provides a backlight module. The backlight module comprises a back plate and a backlight part installed on the back plate. The plurality of backlight parts are arranged on the back plate; an abutted seam is arranged between every two adjacent backlight parts at intervals; an adjusting piece is mounted at each abutted seam; the adjusting piece comprises a connecting part and a connecting part, wherein one end of the connecting part penetrates through the abutted seam to be installed on the back plate; the depth of the connecting part mounted in the back plate is adjustable; the adjusting part is arranged at the end, away from the back plate, of the connecting part, and the outer diameter of the adjusting part is gradually reduced in the direction towards the back plate; one end of the adjusting part enters the abutted seam; the width of the abutted seam is adjusted by adjusting the degree of the adjusting part entering the abutted seam; compared with the prior art, the backlight module is provided with the adjusting part, an operator can finely adjust the width of the abutted seam between the backlight parts through the adjusting part, and all the abutted seams of the backlight module meet the standard requirement.

Description

technical field [0001] The present application relates to the field of display, and in particular, to a backlight module and a display. Background technique [0002] For medium and large size Mini LED display modules, thousands of Mini LEDs are generally welded and evenly distributed on the glass substrate or PCB substrate; if the backlight assembly is welded with Mini LEDs on a whole substrate, it will cause high cost problems. Therefore, in the prior art, a large-sized backlight assembly is generally formed by splicing a plurality of the glass substrates or PCB substrates. In the actual production process, in order to reserve space for the thermal expansion and contraction of the substrate, a seam is generally reserved between two adjacent substrates. [0003] In the actual production process, due to the size tolerance of the backplane and the substrate of the backlight unit, after the backlight module is assembled, the size of the seam of the Mini LED backlight unit will...
