A video display stand having dual panning axes suitable for controlling a screen direction of appliances such as a TV set or a personal computer without bumping against a wall even in a state that it is positioned very closely to the wall, and its controlling method for automatically controlling screen directions by using a driving force, including two motors being installed having gear driving shafts at one side of either a rotational base or a rotation support member of the TV set; two movement guide toothed slots each being formed along a circular arc centering a mutually opposite gear driving shaft with a predetermined width and depth, at the opposite side corresponding to the position of each motor, and having a gear portion to be engaged with the gear driving shaft at one side of each wall; and a controller for controlling driving of the motors.

1. A method for controlling screen direction of the video display stand having dual panning axes for which two motors are selectively driven in a normal direction (clockwise) and in a reverse direction according to a key operation by a user so that a TV set can be turned in the rightward direction or in the leftward direction centering driving shafts of each motor, comprising the steps of:judging whether the key input by the user is a left turn command or right turn command, and the current screen direction of the TV set; driving a motor positioned at the opposite side to the key input command, of the two motors, in the normal direction or in the reverse rotation direction until the key input is released, in case that the current TV set is directed to the front side or is placed in the same direction as the judged turn command; and rotating a motor positioned at the side corresponding to the key input command, of the two motors, in the normal direction or in the reverse direction until the key input is released, in case that the TV set is placed in a different direction to the judged turn command.
