ABSTRACT:
An accessory device for use in connection with a video terminal comprises an attachment mechanism for mounting a display board on either or both sides of a video terminal. The display boards are pivotable about both horizontal and vertical axes. The accessory includes a lighting fixture for illuminating the surface of each display board and a circuit for automatically adjusting the intensity of light produced by each ligthing fixture to maintain a constant predetermined level of illumination on the surface of each display board. The video accessory increases the vertical work surface available for use by a video terminal operator and results in a work station area which is more comfortable for the video operator.
