## Abstract

A backplate assembly is provided. The backplate assembly comprises a backplate and a reinforcing assembly, the reinforcing assembly comprises a peripheral reinforcing member connected to a peripheral portion of the backplate, and a wiring channel is provided at inner side of the peripheral reinforcing member. Preferably, the reinforcing assembly further comprises at least one intermediate reinforcing member connected to the back side of the backplate. The present invention further discloses a backlight module comprising the backplate assembly, and a display device comprising the backlight module.

## Claims

### Claim 1
