Problems solved by technology

However, in actual situations, if the side-type light source is not fixed firmly enough, it will cause the side-type light source to tilt and cause light leakage, which will eventually reduce the display effect of the display.

Abstract

The invention discloses a backlight module and a display device, and relates to the technical field of display. According to the embodiment, a fixed welding foot structure is arranged at the surface of one side, facing to a flexible printed circuit board, of a side-incident light source; a non-electrode welding foot structure corresponding to the fixed welding foot structure is arranged at the surface of one side, facing to the side-incident light source, of the flexible printed circuit board; and the positions of the fixed welding foot structure and a first electrode welding foot structure are set. The stability of the side-incident light source can be greatly improved; the light leakage phenomenon caused by inclination is relieved, so that the quality of a backlight source provided by the backlight module is improved; and the display effect of the display device is improved.

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] A liquid crystal display is a non-self-illuminating display, and requires a backlight source provided by a backlight module to realize a display function. Wherein, the backlight module generally includes a backlight, and the backlight can be divided into a direct-type light source and an edge-type light source. For side-entry light sources, a light guide plate is usually provided on the light-emitting surface of the side-entry light source, and the light guide plate can adjust the propagation direction of the light emitted by the side-entry light source to form a surface light source, thereby providing the liquid crystal display panel with all The required backlight is used to realize the display function. [0003] In order to control the light emission of the side-type light source, a flexible circuit boar...
