The invention relates to a backlight module and a liquid crystal display module. A light guide plate of the backlight module is provided with a top surface and a first bottom surface opposite to the top surface; a light source module is arranged beside the light guide plate; the light source module comprises a printed circuit board and a light-emitting element; the printed circuit board is provided with a loading surface and a second bottom surface opposite to the loading surface; the light-emitting element is arranged on the loading surface of the printed circuit board; one end of the light guide plate abuts on the loading surface of the printed circuit board by means of the first bottom surface; a fixing frame is wound around the light guide plate, and the fixing frame simultaneously abuts on the top surface of the light guide plate and the loading surface of the printed circuit board, so that the fixing frame and the printed circuit board can jointly clamp the end of the light guide plate; and a first adhesive tape is pasted on the outer side of the fixing frame and the second bottom surface of the printed circuit board so as to combine the fixing frame and the printed circuit board. The invention also provides a liquid crystal display module using the backlight module. The invention can save the manufacturing costs of the backlight module and the liquid crystal display module using the backlight module, and is beneficial to improving the assembling efficiencies of the both.
Description
technical field [0001] The invention relates to a light source module and the structure of a display device, and in particular to a backlight module and a liquid crystal display module using the backlight module. Background technique [0002] With the increasing maturity of optoelectronic technology and semiconductor manufacturing technology, flat panel display devices are developing vigorously. Among them, the liquid crystal display has gradually replaced the traditional cathode ray tube display due to its advantages of low voltage operation, no radiation scattering, light weight and small size, and has become the mainstream of display products in recent years. [0003] Generally speaking, a liquid crystal display module includes components such as a backlight module, a liquid crystal display panel, and a front frame. Location. In addition, the backlight module generally includes components such as a light guide plate, an LED light bar as a light source, and a holder. Th...
