Abstract

The invention discloses a backlight module and a liquid crystal display applying the same. The backlight module at least comprises a backboard, a light source arranged on the backboard, a glue frame which is arranged on the periphery of the backboard and positioned outside the light source, and at least one optical diaphragm arranged on the glue frame. The glue frame at least comprises a main body and at least one supporting part spliced with the main body, wherein the main body and the supporting part form a supporting surface and the supporting part allows light to be transmitted. The optical diaphragm is supported on the supporting surface. According to the invention, under the condition of not making the backlight module generate dark bands, the supporting surface of the optical diaphragm can be effectively enlarged to further stabilize and support the optical diaphragm.

Description

technical field [0001] The invention relates to a plane display technology, and in particular to a backlight module and a liquid crystal display using the same. Background technique [0002] Liquid crystal display technology is the most attention-grabbing and fastest-growing display technology among flat-panel display technologies today. With the vigorous development of liquid crystal display technology, next-generation technologies have been developed successively, and the size of liquid crystal displays is also increasing day by day. [0003] Please refer to figure 1 , which is a schematic diagram showing a device of a liquid crystal display panel and an optical film of a known liquid crystal display. The liquid crystal display 100 is mainly composed of a backlight module 108 and a liquid crystal display panel 106 . In the liquid crystal display 100, the optical film of the backlight module 108, such as the diffusion plate 102, and the liquid crystal display panel 106 a...
