Abstract

An angle adjusting device for a display includes a base, a joint disposed between the base and the display. The joint changes an angle of the display. The device includes a first driving motor providing power to one side of the joint, and a second driving motor providing power to the other side of the joint. The joint includes a connecting core, and a first rotating member, a second rotating member, a third rotating member and a fourth rotating member rotatably connected to the connecting core respectively in four directions of the connecting core. The first rotating member and the second rotating member are disposed along a first axis, and the third rotating member and the fourth rotating member are disposed along a second axis perpendicular to the first axis. The third rotating member is rotated based on driving of the first driving motor, and wherein the fourth rotating member is rotated based on driving of the second driving motor.
