Abstract

The present invention provides a light bar and a backlight module using the light bar. The light bar includes: a circuit board (2), a quantum dot rail (4) mounted and fixed to the circuit board (2), and a light source (6) mounted to the circuit board (2) and located between the circuit board (2) and the quantum dot rail (4). The light source (6) is electrically connected to the circuit board (2). In the light bar and the backlight module using the light bar according to the present invention, the retention members are mounted to the circuit board of the light bar to allow the quantum dot rail to be directly mounted to the circuit board through snap engagement so as to enhance color saturation and at the same time simplifying the mounting structure and effectively reducing the manufacturing cost. Further, the retention members are made elastic components that can effectively protect the quantum dot rail from being damaged by external forces acting on the quantum dot rail and can simplifying the process of mounting thereby further reducing the manufacturing cost.
