Problems solved by technology

[0007] An object of the present invention is to provide a backlight module to solve the problem that in the prior art, the light bar is bonded to the backboard by heat-conducting glue, and the bonding position cannot be accurately controlled; and the heat emitted by the light bar during operation causes heat conduction The softening of the glue causes the position of the light bar to move down and cause misalignment, which affects the centering effect of the light bar and the light guide plate, and reduces the incident efficiency of the light bar.

Abstract

The invention discloses a backlight module and a liquid crystal display. The backlight module comprises a back plate, wherein the back plate comprises a back plate main body and a side wall which projects at the two ends of the back plate main body and is integrally molded with the back plate main body; the inner side of the side wall is provided with a luminous part; and a supporting and fixing part is arranged between the luminous part and the back plate main body, and is used for supporting and fixing the luminous part. According to the backlight module and the liquid crystal display, the luminous part can be accurately fixed on the side wall of the back plate, the luminous part is prevented from being staggered even though heat conducting glue for bonding the luminous part is softened by heat dissipated by the luminous part in a working process, the centering effect of the luminous part and a light guide plate is ensured, and the incidence efficiency of the luminous part is increased.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a liquid crystal display. 【Background technique】 [0002] With the continuous development and popularization of liquid crystal display panels, the requirements for components in the liquid crystal display panels are getting higher and higher. [0003] Take the backlight module as an example, please refer to figure 1 , figure 1 It is a schematic structural diagram of a side-illuminated light emitting diode (Light Emitting Diode, LED) backlight module in the prior art. The side-illuminated LED backlight module includes a front frame 11 , a plastic frame 12 , a light bar 13 , a back plate 14 , a light guide plate 15 , and a heat-conducting adhesive 16 . [0004] Wherein, the light bar 13 is fixed on the backboard 14 by the heat-conducting adhesive 16 , and it is generally difficult to ensure that the light bar 13 can be bonded to an accurat...
