Abstract

The invention relates to a phototropic mold train, which comprises a light inlet side. The light source is positioned on one side of light inlet side of the light driving plate. The phototropic mold train also comprises a rotated light-driving pipe which is positioned on one side of light inlet side and which comprises a light inlet end and a light outlet end. The light outlet end transmits the light form light source to the advanced direction.

Description

【Technical field】 [0001] The invention relates to a backlight module, in particular to a backlight module for digital image products. 【Background technique】 [0002] Since the liquid crystal in the panel of the liquid crystal display device cannot emit light itself, in order to achieve the display effect, it is necessary to provide a light source device, such as a backlight module, for the panel of the liquid crystal display device. The function of the backlight module is to provide planar light with sufficient brightness and uniform distribution to the panel of the liquid crystal display device, so that it can display images normally, and thus becomes one of the key components of the liquid crystal display device. [0003] With the continuous expansion of the application field of liquid crystal display devices, especially the application of digital imaging products, such as mobile phones, digital cameras for mobile phones, digital video cameras, etc., the requirements for b...
