Abstract

The invention provides a backlight module which comprises a light guide plate and a light source assembly. The light guide plate has a light-in surface and a light-out surface adjacent to each other. The light source assembly comprises a flexible circuit board and a light-emitting element. The flexible circuit board comprises a main body and a bearing part. The main body is provided with an open hole, the bearing part is arranged in the open hole and provided with a connecting edge, and the connecting edge is connected to the edge of the open hole so that the bearing part can swing relative to the main body. The light-emitting element is arranged on the bearing part and is provided with a light-emitting surface and a back surface opposite to the light-emitting surface. The light-emitting surface faces the light-in surface of the light guide plate. The invention further provides a display device comprising the backlight module. The backlight module provided by the invention is beneficial to improving the light utilization rate and brightness performance, and the display device provided by the invention can improve the display quality.

Description

technical field [0001] The present invention relates to a light source module and a display device, in particular to a backlight module and a display device with the backlight module. Background technique [0002] The liquid crystal display device includes a backlight module and a display panel, and the backlight module is used to provide a display light source to the display panel. The backlight module includes a direct-type backlight module and a side-type backlight module. The side-type backlight module has the advantage of being thinner because the light source is arranged next to the side (light incident surface) of the light guide plate, which is conducive to reducing the size of the entire liquid crystal display. The thickness of the device. [0003] Existing side-type backlight modules widely use light-emitting diode strips as light sources. The LED light bar includes a circuit board and a plurality of LEDs, wherein the LEDs are arranged on the carrying surface of ...
