An automated tilt head assembly for tilting of an electronic display screen from a vertical plane and for rotation of the tilt head assembly about a vertical axis of rotation. The automated tilt head assembly generally includes a mobile carrier surface to which an electronic display device is mounted, a guide system for defining a range of tilt motion about a tilt axis, and a power-driven unit having a motor and gear assembly for automatically and selectively controlling the tilt motion. The motor drives a worm member, which by means of a gear, mates with a toothed sector of the mobile carrier surface, to thereby control the tilt motion of the mobile carrier surface. The tilt head assembly further includes a second power-driven unit having a motor and gear assembly to control rotation of the head assembly about a vertical axis.
