Abstract

The invention discloses a backlight source, a backlight module and a display device. The backlight source comprises at least two substrates correspondingly arranged on the same plane and a plurality of first light-emitting elements, wherein the first light-emitting elements are arranged on the same side surfaces of the at least two substrates; the backlight source further comprises a second light-emitting element, the second light-emitting element is arranged in a gap between the two adjacent substrates and clamped by the two adjacent substrates, and the first light-emitting element and the second light-emitting element are both electrically connected with circuits on the surfaces of the substrates. A first chip on film is further arranged on the face, back on to the first light-emitting element, of the substrate, the first chip on film is electrically connected with a circuit on the surface of the substrate through the wiring hole, and the first light-emitting element and the second light-emitting element are driven through the first chip on film. According to the invention, the second light-emitting element is added at the position of the splicing section of the splicing substrate, and the second light-emitting element is used for light reinforcement, so that the problem of brightness and darkness formed by splicing the substrates is solved, and the existence of black lines in partial areas is improved.

Description

technical field [0001] The present application relates to the technical field of display device fabrication, and in particular, to a backlight source, a backlight module and a display device. Background technique [0002] With the continuous impact of OLED (Organic Light-Emitting Diode, organic light-emitting diode) technology, LCD (Liquid Crystal Display, liquid crystal display) backlight technology is also constantly expanding innovation. Therefore, a mini LED (miniature light-emitting diode) backlight source with better contrast and picture expression was developed. [0003] As a backlight source, mini LED is composed of multiple partitions, which can individually control the brightness of each small area, greatly improving its display effect. Compared with traditional edge-lit backlight modules, mini LED backlight modules are currently attracting more attention due to their high brightness, ultra-narrow bezels, and the ability to control light in zones and special shape...
