Problems solved by technology
[0005] The present invention provides a backlight module. The light source and the main flexible circuit board are contacted and connected through metal contacts to solve the existing backlight module. The light source is welded to the main flexible circuit board. The welding and desoldering need to increase the machine process and manpower. And it will damage the components, which will increase the production cost and affect the technical problems of product quality.

Embodiment Construction
[0044] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.
[0045] The present invention is aimed at the small-sized backlight module of the prior art. The light source and the main flexible circuit board are connected by welding. The welding and desoldering need to increase the machine process and manpower, and damage the components, which will increase the production cost and affect the product quality. technical problem, thi...

The invention provides a backlight module which comprises a back plate, a plastic frame, a light source, a light guide plate, a reflective sheet and an optical film. The edge of the back plate extends upwards to form a retaining wall, a pin exposure gap is formed in one side of the retaining wall close to the light source, a secondary flexible circuit board is attached to the surface of the plastic frame, a connecting portion is arranged on one side of the secondary flexible circuit board, a metal pin is arranged on the surface of the connecting portion and positioned in the pin exposure gap, and the secondary flexible circuit board is in contact connection with an elastic contact on a primary flexible circuit board through the metal pin. Compared with an existing backlight module, the backlight module has the advantages that the metal pin is led out of the light source, extends into an avoidance gap and is exposed to the back plate, the secondary flexible circuit board is in contact connection with the primary flexible circuit board through the metal pin, increase of machine processes and labor cost caused by welding is avoided, and the technical problem of possible damage to components is solved.
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 with the backlight module. Background technique [0002] At present, liquid crystal display devices, as display components of electronic equipment, have been widely used in various electronic products, and a backlight module is an important part of the liquid crystal display devices. [0003] Such as figure 1 As shown, it is a small and medium size backlight module (different from large size) in the prior art, including: a plastic frame 101, a reflector 102, a light guide plate 103, an optical film set 104, and a light source flexible circuit board 105 , LED106, main flexible circuit board 107, display screen 108, etc., the light source flexible circuit board 105 and LED106 are fixed on the light guide plate 103 and the plastic frame through the light-shielding tape, and the optical film group 104 is fixed on the lig...
