US Patent 10912207 Display apparatus

A display apparatus includes a base unit, a monitor and a rotating member. The base unit includes a base seat, and a support member adapted to be in contact with a reference surface. The monitor is secured to the base unit. The rotating member is mounted to the base seat and has an annular surrounding surface surrounding a substantially-horizontal rotational axis, protruding outwardly of the top and bottom walls, and adapted to be in frictional contact with the reference surface. The rotating member is rotatable about the rotational axis to result in rotation of the base seat about the support member relative to the reference surface.
