Beschreibung
Zusammenfassung:	The backlight module comprises a back plate, a light source, a diffusion plate and a supporting assembly, the light source is arranged on the back plate, the diffusion plate is located on the light emitting side of the light source, the supporting assembly is connected between the back plate and the diffusion plate, the supporting assembly comprises a supporting base and an elastic supporting piece, and the elastic supporting piece is arranged on the supporting base. The supporting base is fixedly connected with the back plate, the elastic supporting piece is arranged on the side, close to the diffusion plate, of the supporting base, a plurality of concave dimming grooves are formed in the elastic supporting piece, and the dimming grooves are used for reflecting or refracting part of light emitted by the light source to the diffusion plate. The supporting column has the advantages that the problems that an existing supporting column is prone to damaging a light source diaphragm, brightness distribution of a l
