## Abstract

A method for bonding a housing and a screen, a housing assembly, and a mobile terminal, where the bonding method includes bonding, to an inner surface of the housing, a polymer layer including a plurality of vias, dispensing glue on the polymer layer bonded on the inner surface of the housing, and bonding the glued polymer layer with the screen. Therefore, the method for bonding the housing and the screen, the housing assembly, and the mobile terminal can expand a specific surface area of glue and enhance bonding strength between the housing and the screen.
