Therefore, it has been widely used in communication and information for several decades. And in the field of home life, such as mobile phones, wireless phones, fax machines, industrial instruments, machines = and audio and video appliances. Since the liquid crystal itself does not emit light, it is necessary to provide the brightness required for the panel by the backlight, so the backlight module is a key component of the liquid crystal display panel. The structure of the moonlight module can be divided into two types: an edge-light structure and a direct-type structure. The light source of the edge-light structure is a single light source on the side, and the light beam is used to reflect the side light to the front side of the panel, and has the characteristics of light weight, thin shape, narrow frame, low power consumption, etc., and is suitable for providing small and medium size. Display devices, such as mobile phones, personal digital assistants (PDAs), and light sources for notebook computers. Larger-sized multimedia playback devices, such as LCD TVs, require an oversized moonlight module for straight-down structures that do not contain a light guide and that have a light source placed directly below, which can be advantageous in terms of brightness and weight. At present, in the application of large-sized panels, since the cold cathode fluorescent lamp (CCFL) has a price advantage over the light-emitting diode (hght-emitting diode), the cold cathode lamp 200807097 tube Still the main light source for large LCD panels. In the trend of large size and low price, the backlight module must have a large surface, light weight, thinness, low power consumption, redundancy and low cost.
