Abstract

The invention provides a backlight module and a display device. The backlight module comprises a backboard, a light source, a light guide member, a diffusion sheet and a prism sheet, the light sourcecomprises a first light bar and a splicing unit, which are disposed on the backboard in a splicing manner, the light guide member is disposed in a splicing area, the diffusion sheet is disposed on thelight guide member for uniformly emitting light, and the prism sheet is disposed on the diffusion sheet, wherein, the light guide member is used for transmitting the light, which cannot be transmitted by the light source to the diffusion sheet in the splicing area, to the diffusion sheet in the splicing area; and by disposing the light guide member in the splicing area, the light guide member transmits the light, which cannot be transmitted by the light source to the diffusion sheet in the splicing area, to the diffusion sheet in the splicing area, in this way, the light intensity on the diffusion sheet in the splicing area is enhanced, so that the splicing area can achieve normal display, and the technical problem that the existing display device using spliced miniLED has splicing dark lines at the splicing location is alleviated.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] The existing miniLED is used as a direct-lit display backlight, which has the advantages of high brightness, high contrast, partial display, and narrow frame. When splicing mini LEDs, there will be obvious splicing gaps at the splicing place, and when displaying, there will be splicing dark lines, which will affect the display effect. [0003] Therefore, the existing display devices using spliced ​​mini LEDs have the technical problem of splicing dark lines at the splicing places. Contents of the invention [0004] The present invention provides a backlight module and a display device, which are used to solve the technical problem of splicing dark lines at splicing places in existing display devices using spliced ​​miniLEDs. [0005] In order to solve the above problems, the technical solutions provided b...
