Description

【Technical field】

[0001] The invention relates to a backlight module, in particular to a backlight module used in digital video products. 【Background technique】

[0002] Since the liquid crystal in the panel of the liquid crystal display device does not emit light itself, in order to achieve the display effect, it is necessary to provide the panel of the liquid crystal display device with a light source device, such as a backlight module, whose function is to provide the panel of the liquid crystal display device with sufficient brightness and uniform distribution. Planar light enables it to display images normally, so it becomes one of the key components of liquid crystal display devices.

[0003] With the continuous expansion of the application field of liquid crystal display devices, especially the application of digital imaging products, such as digital cameras for mobile phones, digital video cameras, etc., the requirements for the backlight module of liquid crystal dis...
