Abstract

A terminal display assembly may include a display screen, a light-transmission cover plate, optical means and a seal ring. The display screen may define a through hole penetrating the display screen in a thickness direction of the display screen. The light-transmission cover plate may be disposed on the display screen and cover the through hole. A least part of the optical means may be disposed in the through hole. The seal ring may be disposed on the optical means, sandwiched between the optical means and the light-transmission cover plate, and contact with the light transmission cover plate.
