[Prior Art] The backlight module refers to an optical component that can provide a surface light source, and is currently widely used in liquid crystal displays (LCDs) of various information, communication, consumer products and the like. Generally speaking, the backlight module is mainly composed of three parts: a lampshade, an optical film and a light source.

Taking a direct-lit backlight module as an example, a cold cathode fluorescent lamp (CCFL) is generally used as a light source. However, as the size of the display increases, the tube and the optical film located inside the backlight module are prone to distortion of the curve due to gravity, heat, and internal stress, thereby affecting the display quality of the display. In order to solve this problem, the prior art uses a lamp holder to fix both ends of the tube and to provide a lamp carrier on the reflector of the backlight module to avoid warpage of the tube. Another design is to provide a plurality of support members between the reflector and the other optical film for carrying and fixing the lamp tube while supporting the optical film to prevent the lamp S and the optical film from being subjected to gravity, heat, and internal stress. Insufficient rigidity results in warping deformation.
