Problems solved by technology

After the backlight forms the display module, the FPC lead-out of the light bar needs to be folded 180°, and the refraction force acts on the light bar, causing pull on the light bar, which will cause separation between the light bar FPC and the light guide plate, resulting in display Inhomogeneity

Abstract

The invention discloses a backlight, a display screen module and a display device, wherein the backlight comprises a light guide plate; a light bar FPC, comprising a main body part and a leading-out part. The main body part mentioned above is attached to one side of the light guide plate and positioned at the edge of the light guide plate. The leading-out part mentioned above includes a pluralityof leading-out ends, which are connected with the main body part. And an interval is arranged at the joint between the main body parts and a plurality of leading-out ends. According to the backlight of the invention, when the leading-out part is bent, the bending force can be dispersed to multiple leading-out ends, which can relatively reduce the bending force on each leading-out end and reduce the risk of separation of the light bar FPC and the light guide plate, thereby reducing the risk of uneven display of the light guide plate by making the leading-out part be provided with multiple intervals and leading-out ends connected with the main body part.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a backlight source, a display screen module and a display device. Background technique [0002] In related technologies, display devices such as mobile phones are rapidly developing toward full screens. The upper and lower borders of display devices such as mobile phones are becoming narrower and narrower, and the design requirements for liquid crystal display screens are getting higher and higher. Design requirements are getting closer and closer to the limit. In order to achieve a full screen effect and pursue a larger screen-to-body ratio, the design space left for the backlight strip in the backlight is squeezed very narrow. In this context, the adhesive area of ​​the light strip is also squeezed to a small size . After the backlight forms the display module, the FPC lead-out of the light bar needs to be folded 180°, and the refraction force acts on the light bar, c...
