Abstract
A light bar, a backlight module and a liquid crystal display are provided. The backlight module includes the light bar and a backplane, the light bar includes a PCB, a plurality of LED chips arranged on a surface of the PCB and a protrusion arranged on the other surface of the PCB, and the backplane includes a baseboard defining a through groove. The protrusion on the PCB is inserted into the through groove of the backplane to facilitate heat conduction. In this way, heat generated by the LED chips could be conducted out quickly.

A light bar applied to a backlight module comprising a backplane, the light bar comprising:
- a PCB defining first and second surfaces;
- and
- a plurality of LED chips arranged on said first surface of the PCB, whereby said second surface of the PCB defines a protrusion that penetrates through the backplane to facilitate heat conduction.
A backlight module, comprising:
- a light bar, comprising a PCB defining first and second surfaces;
- a plurality of LED chips arranged on said first surface of the PCB, whereby the second surface of the PCB defines a protrusion;
- a backplane, comprising a baseboard defining a through groove, wherein said protrusion of the PCB is inserted into the through groove to facilitate heat conduction.
A liquid crystal display (LCD), comprising a backlight module comprising:
- a light bar, comprising a PCB, a plurality of LED chips arranged on a first surface of the PCB, a second surface of the PCB having a protrusion;
- a backplane, comprising a baseboard defining a through groove, wherein the protrusion is inserted into the through groove to facilitate heat conduction.
