Abstract

The present invention relates to one kind of back light module for digital image product. The back light module includes one light source, one light guiding board and one light reflecting element. The light guiding board includes one light incoming plane, the light source is set oppositely to the light incoming plane, and the light reflecting element is set between the light source and the light guiding board. When the back light module is converted from the flash operation state to the back light operation state, the light reflecting element moves between the light source and the light guiding board.

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...
