Abstract

A light strip assembly (30) comprises a light source (301), a circuit board (302), and a connector (303). The circuit board (302) comprises a first support portion (3021) and a bent portion (3022) that is bent relative to the first support portion (3021). The light source (301) is disposed on the first support portion (3021). The connector (303) is electrically connected to the light source (301), and the connector (303) is disposed on the bent portion (3022). A backlight module (300) comprises the light strip assembly (30). By disposing the bent portion (3022) on the circuit board (302) and disposing the connector (303) on the bent portion (3022), it is avoided that a light-guiding plate (705) is cut at the corresponding connector (303), so that the risk of light leakage of the backlight module (300) is reduced and the reliability of the backlight module (300) is increased.

Description

technical field [0001] The invention relates to the technical field of liquid crystal backlights, in particular to a light bar assembly and a backlight module. Background technique [0002] At present, the light strip components used in the current mass-produced LCD backlight modules are all straight strips, such as figure 1 A light bar assembly in the prior art shown mainly includes a light source 101, a circuit board 102 and a connector 103, wherein the light source 101 and the connector 103 are located on the same side of the circuit board 102, and the circuit board 102 is strip-shaped, The plane where the upper surface of the connector 103 is higher than the plane where the upper surface of the light source 101 is located. When the light source of this structure is used in the backlight module, such as figure 2 As shown, since the upper surface of the connector 103 protrudes from the plane where the upper surface of the light source 101 is located, the light guide pla...
