Description

【Technical field】 [0001] The invention relates to a backlight module and a liquid crystal display using the backlight module. 【Background technique】 [0002] Liquid crystal display is a kind of non-self-luminous display device, and its display is mainly realized by controlling the passage or non-passage of the light beam emitted by the external light source. Therefore, an external light source and a corresponding light guide device, such as a backlight module, are usually required. The light beam emitted by the external light source can be directed to the display panel. [0003] Usually, a backlight module mainly includes a light source, a light source cover, a light guide plate, a flexible printed circuit board (Flexible Printed Circuit Board, FPC) and other optical components. fixed. [0004] A prior art backlight module is shown in FIGS. 1 and 2 . The backlight module 10 includes a flexible circuit board 11 , a frame 13 , a light emitting element 15 and a light guide pl...
