Abstract

Present disclosure discloses a display screen module and a display screen, which includes a front panel, a rear panel and a circuit module. The circuit module includes a driving device, a plurality of display assemblies and a substrate located between the front panel and the rear panel. The substrate includes a first mounting plate and second mounting plate which are integrated. The second mounting plate is formed by extension from one end of the first mounting plate along a horizontal direction. Each of the plurality of display assemblies includes a plurality of lamp beads provided at intervals on the substrate along an extension direction of the second mounting plate and facing the front panel. The driving device is arranged on the first mounting plate and partially protrudes from the rear panel. A size of the driving device is less than or equal to a size of the first mounting plate.
