Problems solved by technology

However, there are problems such as warping and black border cutting at the splicing position of adjacent light panels, which will cause dark lines at the splicing position of the large-size backlight formed by splicing, and cause the brightness of the splicing position to be inconsistent with the normal light-emitting area, which is serious. Affect the light quality of the backlight module

Abstract

The invention discloses a spliced backlight module and a display device, and relates to the technical field of display, the spliced backlight module comprises at least two lamp panels adjacently arranged in a first direction, each lamp panel comprises a first light-emitting area and a second light-emitting area, and the first direction is parallel to the light-emitting surface of the backlight module; wherein the first light-emitting area comprises a first light-emitting element, the second light-emitting area comprises a second light-emitting element, and the light-emitting direction of the first light-emitting element is different from the light-emitting direction of the second light-emitting element; an optical film; and the orthographic projection of the light supplementing area on thelight emitting surface covers the orthographic projection of the second light emitting area on the light emitting surface in the direction perpendicular to the light emitting surface of the backlightmodule. Due to the fact that the first light-emitting element serves as the backlight source, and the second light-emitting element serves as the light supplementing light source, the emergent lightof the second light-emitting element emitting light laterally can irradiate the light supplementing area, the brightness of the abutted seam of the lamp panels is improved, dark lines are eliminated,and the light emitting quality of the backlight module is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a spliced ​​backlight module and a display device. Background technique [0002] Mini LED chip is an LED chip with a chip size of about 100μm×100μm. Because of its advantages of high brightness, energy saving, and local dimming, more and more manufacturers choose Mini LED as the backlight source in display devices. [0003] At present, limited by the manufacturing process, Mini LED products are all packaged into small-sized light panels. In order to realize the large-size Mini LED backlight, multiple small-size light panels can only be spliced ​​together. However, there are problems such as warping and black border cutting at the splicing position of adjacent light panels, which will cause dark lines at the splicing position of the large-size backlight formed by splicing, and cause the brightness of the splicing position to be inconsistent with the normal light...
