Since the liquid crystal itself does not emit light, the function of the backlight module is to supply sufficient brightness and a uniformly distributed light source to enable normal display of images. Liquid crystal displays are now widely used in electronic products with growth potential such as monitors, notebook computers, digital cameras and projectors. The demand for backlight modules and related components continues to be long: The lamp tube in the conventional backlight module utilizes a lamp holder structure for the back bezel. Where the lamp holder structure is combined with the f-plate, a corresponding hook is formed to hold the lamp holder structure on the back plate. It is easy to burn and cause damage. The fixing is poor. When used, the hook of the lamp holder structure is protruding from the back plate and is bad. Moreover, the contact area between the hook and the back plate is small, and a resonance problem occurs in fixation, and noise is generated. In addition, the traditional method of holding the lamp holder structure on the back plate is only suitable.
