The edge of the cover plate 111 may be covered on the middle frame 121 and sealed with the middle frame 121. So that the display module 112 can be enclosed in the casing 120 . Referring to FIG. 3 , which is a partial sectional view of A-A in FIG. 1 , the display module 112 may include a display layer 1121 and a circuit board 1122 laminated with the display layer 1121 .
